Abstract

Apparatus and related methods relate to an alignment system including an alignment source module (ASM) and an alignment indicator module (AIM), the AIM and ASM configured to releasably couple to first and second units of a pair of optoelectronic arrays, respectively. In illustrative examples, when coupled, the ASM can be oriented to emit a light beam that substantially aligns with a first optical axis of the first unit. For example, when coupled, the AIM can be configured to provide a visible indication when the light beam is within a predetermined close-to-alignment orientation range relative to a second optical axis of the second unit. For example, each of the AIM and ASM can be configured for axial coupling along respective longitudinal axes of the first and second units. Various embodiments can advantageously facilitate maneuvering the pair of optoelectronic arrays into close-to-alignment with one another.

[0012] background

[0013] Manufacturing facilities produce useful articles by processing parts into finished products. The operations used to process parts may involve transformation steps that change the article from one state to another. Some of these transformation operations employ machinery, such as presses, cutting tools, conveyor systems, ovens, or chemical applicators.

[0014] Some manufacturing facilities use machinery that can pose a danger to humans. For example, a worker entering the operating area of ​​a large robotic arm risks serious bodily injury if the arm's trajectory intersects with the worker's body or clothing. In another example, a worker placing a workpiece into a press and reaching their hand inside while it is activated could suffer serious injury.

[0015] To enhance operator and machine safety, many manufacturing machines are protected, partially or entirely surrounded by light curtain systems. A light curtain safety system can deactivate a machine when an object interrupts any part of the light curtain's sensing area. For example, a hand extending through the light curtain might block one or more beams, which the light curtain might interpret as a potential hazard. The light curtain can typically respond by deactivating the machine, for example, by engaging a braking system and / or interrupting power to the motor drive that moves the press. A light curtain safety system can also prevent machine activation when an object is present in any part of the light curtain's sensing area. For example, an operator standing too close to the machine or in a hazardous area near the machine before it is started might block one or more beams of the light curtain. The light curtain might interpret this as a hazard and prevent the machine from starting. European patent application serial number EP 0964273 A2 filed by Kiyoshi Hama et al. discloses an area sensor comprising a light emitter with multiple light-emitting devices. International application WO 2017 / 023942, filed by Matthew Gelineau et al., discloses apparatus and associated methods related to modular plug-in attachments. U.S. patent application 2016 / 0043801A1, filed by Hans Grimm et al., discloses a method for aligning a sensor system.

[0016] Overview

[0017] The apparatus and related methods relate to an alignment system including an alignment source module (ASM) and an alignment indicator module (AIM), configured to be releasably coupled to a first and a second unit of a pair of optoelectronic arrays, respectively. In an illustrative example, when coupled, the ASM can be oriented to emit a beam substantially aligned with a first optical axis of the first unit. For example, when coupled, the AIM can be configured to provide a visible indication when the beam is within a predetermined proximity alignment orientation range relative to a second optical axis of the second unit. For example, each of the AIM and ASM can be configured to be axially coupled along a respective longitudinal axis of the first and second units. Various embodiments can advantageously facilitate manipulating the pair of optoelectronic arrays to bring them close together for alignment.

[0018] Various embodiments can achieve one or more advantages. For example, some embodiments can advantageously facilitate operator manipulation of a first and / or second unit in a pair of photoelectric arrays into a (proximity) alignment state, in which a light curtain can be generated and / or an automatic alignment system can be advantageously employed. For example, some embodiments can advantageously actively generate one or more visual markers, such as, for example, to guide the user in aligning one or more units. Many embodiments can advantageously provide rapid, guided alignment of two photoelectric units without the excessive and / or frustrating "guesswork" manipulation that attempts to achieve a (predetermined) alignment level suitable for alignment and / or for performing a final (precise) alignment method.

[0019] In various embodiments, for example, the alignment module can be advantageously pluggably and releasably coupled to a desired orientation for alignment. For example, various embodiments can advantageously provide axial coupling between the pluggable alignment module and the end of the optical rod. For example, such embodiments can advantageously prevent obstruction of one or more elements of the optoelectronic array of the optical rod.

[0020] For example, a light bar may include an array of optical emitting elements. For example, the light bar may extend along a longitudinal axis. For example, the optical emitting elements may be distributed along an array axis parallel to the longitudinal axis. For example, the optical emitting elements may emit light in at least one plane substantially orthogonal to the array axis. For example, the light bar may be equipped with one or more optical receivers. For example, the receivers may be distributed along a second array axis substantially parallel to the longitudinal axis. For example, the receivers may be configured to detect light incident in one or more planes substantially orthogonal to the second array axis.

[0021] For example, various embodiments can advantageously disable the touch input terminal, thereby advantageously preventing accidental activation of the transmitter. For example, some embodiments can advantageously provide pluggable cascading of optoelectronic units.

[0039] Detailed Description of Illustrative Embodiments

[0040] To aid understanding, this document is organized as follows. First, to facilitate the discussion of various embodiments, refer to... Figure 1 An exemplary pluggable alignment system is described. Next, the description leads to a reference. Figures 2-3 Description of exemplary system embodiments. Third, refer to Figures 4-12 An exemplary pluggable alignment module is depicted. Fourth, refer to... Figures 13-14 The document discusses exemplary methods related to operating the pluggable alignment module. Finally, it discusses additional embodiments, exemplary applications, and aspects related to the pluggable alignment system.

[0041] Figure 1 An exemplary pluggable alignment module (PAM) is depicted in an illustrative use case scenario. In the depicted exemplary scenario 100, a machine 105 (e.g., a hydraulic press) is deployed (e.g., on a shop floor). For example, machine 105 may require safety protection. For example, machine 105 can be protected to avoid injury to workers using machine 105. In this example, an opto-safety device (e.g., a pair of light bars) is installed to protect machine 105. The opto-safety device includes a first unit 110 and a second unit 115. The first unit 110 and the second unit 115 are configured to generate a light curtain 120. After successful installation, the light curtain 120 can be configured, for example, to stop operation of machine 105 if the light curtain 120 is interrupted.

[0042] For example, the operation of the photoelectric safety device may depend on the proper alignment of the first unit 110 and / or the second unit 115. For example, the light curtain 120 may be generated only when the photoelectric array (e.g., sensor, transmitter) of the first unit 110 is registered with the photoelectric array of the second unit 115. For example, the first unit 110 and / or the second unit 115 may be pre-aligned by an operator. By way of example, and not limitation, pre-alignment may include using a level, visual alignment of the first unit 110 and / or the second unit 115 with each other (e.g., by the human eye), or some combination thereof. By way of example, and not limitation, the first unit 110 and / or the second unit 115 may include an automatic alignment system to precisely align the first unit 110 and / or the second unit 115 with each other. For example, the automatic alignment system may require a minimum threshold alignment for successful application. For example, the automatic alignment system may require the first unit 110 and / or the second unit 115 to be within a (predetermined) angular range (e.g., "proximity alignment") about the longitudinal axis of the corresponding photoelectric array. For example, an automatic alignment system may require alignment of a minimum angle between the longitudinal axes of the first unit 110 and the second unit 115 (e.g., relative to a parallel direction). For example, minimum alignment may be difficult to achieve by unassisted visual alignment of the first unit 110 and / or the second unit 115 (e.g., by "visual" alignment) and / or by external alignment tools.

[0043] In the depicted exemplary scenario 100, a first unit 110 is equipped with a first pluggable alignment module 125. The first pluggable alignment module 125 is coupled (pluggably and / or releasably) to an end of the first unit 110 along its longitudinal axis. The first pluggable alignment module 125 is equipped with a touch input and indication module 130. An emitter 135 emits a light beam 140 (e.g., a laser beam). The first pluggable alignment module 125 is coupled to the first unit 110 such that the emitter 135 emits a light beam 140 substantially parallel to the optical axis of the photoelectric array of the first unit 110.

[0044] A second pluggable alignment module 145 (releasably and pluggably) is coupled to the second unit 115. In the depicted example, the second pluggable alignment module 145 includes an indicator module 150. For example, the indicator module 150 may be made at least partially of a material having a reflective surface. As shown, the first unit 110 is rotating, thereby rotating the light beam 140. For example, the reflective surface may generate at least one visual mark when the light beam 140 illuminates the indicator module 150. For example, the visual mark may indicate that the first unit 110 and / or the second unit 115 are close to each other in alignment. For example, the visual mark may indicate that the respective longitudinal axes of the first unit 110 and the second unit 115 are close to parallel alignment and / or indicate that the optical axes of the first unit 110 and the second unit 115 are close to parallel alignment. Thus, the operator can advantageously manipulate the first unit 110 and / or the second unit 115 into an alignment state in which a light curtain 120 can be generated and / or an automatic alignment system can be advantageously employed.

[0045] In the depicted example, the first pluggable alignment module 125 also includes a coupling module 155 having a plug module 160. The coupling module 155 can be configured to align the first pluggable alignment module 125 along the longitudinal axis of the first unit 110 and releasably couple it to an end of the first unit 110. For example, the coupling module 155 can be configured to rotatably orient the first pluggable alignment module 125 about the longitudinal axis. The plug module 160 can electrically couple the first pluggable alignment module 125 to the first unit 110. For example, the plug module 160 can operatively couple a transmitter 135 to a power source of the first unit 110.

[0046] As shown, the first pluggable alignment module 125 also includes an indicator module 150. For example, the indicator module 150 may be configured to generate at least one visual mark in response to illumination light (e.g., a laser beam) from the opposing alignment module. For example, in some embodiments, the second pluggable alignment module 145 may be equipped with an emitter 135 (not shown in the depicted example). For example, such embodiments may advantageously allow for more accurate alignment of the second unit 115 with the first unit 110. For example, the first unit 110 and the second unit 115 may each be sequentially and repeatedly aligned until the beam 140 and the beam emitted from the second pluggable alignment module 145 are each aligned with a (predetermined) target (e.g., the center, the visible aperture of the emitter 135) of the opposing alignment module.

[0047] In the depicted example, the second pluggable alignment module 145 is equipped with a coupling module 165. As shown, the coupling module 165 is not equipped with a plug module 160. For example, an embodiment without a plug may not have a transmitter 135. For example, an embodiment without a plug may have another power source. By way of example and not limitation, such an embodiment may have an internal power source (e.g., a rechargeable and / or replaceable battery), solar energy, external electrical couplings (e.g., wires and plugs), or some combination thereof.

[0048] Figure 2 An exemplary block diagram of an exemplary PAM is depicted. An exemplary pluggable alignment system 200 includes an alignment unit 205 coupled to an optoelectronic unit. In the depicted example, the optoelectronic unit is a first unit 110 (labeled "light bar"). The alignment unit 205 includes a transmitter 215. The transmitter 215 is operatively electrically coupled to an operator control input receiver 220. For example, the operator control input receiver 220 may include a switch. For example, an operator can operate the operator control input receiver 220 to enable and / or disable the transmitter 215.

[0049] The first unit 110 includes a power source 225. For example, the power source 225 may include an internal power source (e.g., a battery). For example, the power source 225 may include an external power source (e.g., a building power source accessed via a pluggable connection to an electrical outlet in the building). For example, the first unit 110 may include power control circuitry configured to modify, regulate, and / or distribute power from internal and / or external power sources.

[0050] Alignment unit 205 is mechanically (e.g., releasably, pluggably) coupled to first unit 110, as indicated by the double lines. Operator control input receiver 220 operatively (electrically) couples power supply 225 of first unit 110 to transmitter 215. Thus, transmitter 215 can selectively receive power from power supply 225.

[0051] Figure 3 An exemplary block diagram of an exemplary PAM equipped with a through connector module and a touch input module is depicted. An exemplary pluggable alignment system 300 includes an alignment unit 305 coupled to two optoelectronic units.

[0052] Alignment unit 305 includes controller 310. For example, controller 310 may include control circuitry. Controller 310 includes a microprocessor 311 (labeled "μP") operatively coupled to a non-volatile memory module 312 (labeled "NVM") and a random access memory module 313 (labeled "RAM"). For example, non-volatile memory module 312 may store at least one instruction program. For example, microprocessor 311 may be configured to execute at least one instruction program to perform operations for photoelectric array alignment.

[0053] Controller 310 is operatively electrically coupled to transmitter 315 and operator control input receiver 320. Controller 310 can be configured to selectively activate and / or deactivate transmitter 315 in response to input from operator control input receiver 320. For example, an operator can manipulate operator control input receiver 320 to generate at least one signal configured to cause controller 310 to operate transmitter 315.

[0054] Controller 310 is operatively electrically coupled to touch input terminal 325. For example, touch input terminal 325 may be configured to operate operator control input receiver 320. By way of example, and not limitation, in some embodiments, operator control input receiver 320 may be integrated with touch input terminal 325, such that operation of touch input terminal 325 can operate operator control input receiver 320. By way of example, and not limitation, in some embodiments, touch input terminal 325 may be configured as operator control input receiver 320. By way of example, and not limitation, in some implementations, touch input may correspond to a part of the user's body touching (e.g., contacting) touch input terminal 325. For example, a transducer (e.g., touch input terminal 325) may respond to touch input without translation (e.g., no translation at all, or minimal translation). For example, such embodiments may advantageously reduce the number of moving parts and / or provide easy access (e.g., to a large portion or the entirety of the dome) for input to the user without the need for specialized manipulation of moving parts.

[0055] In some implementations, for example, the transducer can be configured as a "button", toggle, slider, knob and / or joystick, which can move, bend, rotate and / or shift in response to user input (e.g., pressing a button, manipulating the transducer).

[0056] The controller 310 is operatively electrically coupled to the receiver 330. For example, the receiver 330 may include one or more circuits configured to convert incoming electromagnetic signals. For example, the receiver 330 may be configured as an optical sensor. For example, the optical sensor may be configured to generate at least one signal received by the controller 310 in response to an incoming optical signal (e.g., a laser beam).

[0057] Controller 310 is operatively electrically coupled to indicator module 335. For example, indicator module 335 may generate one or more visual markers in response to one or more electrical signals from controller 310. By way of example and not limitation, controller 310 may generate electrical signals such that indicator module 335 generates one or more visual markers in response to one or more signals from receiver 330, which in turn are generated in response to an incoming electromagnetic signal. Thus, various embodiments may advantageously generate one or more visual markers actively, for example, to guide a user to align first unit 110 and / or an opposing unit (e.g., second unit 115). For example, (active) visual markers may indicate to the user the direction required for alignment of the operating unit. For example, visual markers may indicate the position of an optical being being illuminated. For example, visual markers may indicate the level of alignment achieved (e.g., misaligned, roughly aligned, almost aligned, perfectly aligned, ready to activate the automatic alignment system).

[0058] Alignment unit 305 is mechanically coupled to first unit 110 (labeled "light bar"), as indicated by the double lines. Alignment unit 305 is electrically coupled to first unit 110 such that controller 310 is electrically coupled to power supply 225 of first unit 110. Alignment unit 305 is also equipped with through connector module 340. Power supply 225 is operatively electrically coupled to through connector module 340.

[0059] The connected optoelectronic unit 345 (labeled "light bar") is coupled to the first unit 110 via alignment unit 305. As shown, the connected optoelectronic unit 345 includes a power circuit 360. The power circuit 360 is electrically coupled to a through connector module 340. Thus, the power circuit 360 is operatively electrically coupled to a power source 225 via the through connector module 340. For example, the connected optoelectronic unit 345 can be "daisy-chained" to the first unit 110 via alignment unit 305. Thus, for example, power can be advantageously supplied to the connected optoelectronic unit 345 via the first unit 110 using shorter cables (e.g., only from alignment unit 305 to the connected optoelectronic unit 345, rather than directly from a central power source to the connected optoelectronic unit 345). For example, various such embodiments can advantageously simplify wiring. Such embodiments can reduce the cost of laying cables. Various such embodiments can reduce tripping hazards.

[0060] The first unit 110 is equipped with an optoelectronic array 350. The optoelectronic array 350 is electrically coupled to a power supply 225. A connected optoelectronic unit 345 is equipped with an optoelectronic array 355. The optoelectronic array 355 is electrically coupled to a power circuit 360. Therefore, the optoelectronic array 355 is operatively electrically coupled to the power supply 225 via a pass-through connector module 340. For example, in some embodiments, the optoelectronic arrays 355 and 350 may be coupled via the pass-through connector module 340 (e.g., via a data signal conduit). For example, in various embodiments, the pass-through connector module 340 may include one or more ports. For example, the pass-through connector module 340 may include one or more individual wires. In some embodiments, the pass-through connector module 340 may include multiple sets of wires (e.g., cables with bundled wires, for example, for data and / or power).

[0061] Figure 4 An exemplary PAM with a reflective module and an optical emitter is depicted. The exemplary pluggable alignment module 400 includes a housing 405. The housing 405 is equipped with an emitter 135 and an indicator module 150. The housing 405 is also equipped with an alignment member 410. As shown, the alignment member 410 extends from the housing 405 substantially parallel to the photoelectric unit (e.g., at least relative to...). Figure 1 The longitudinal axis of the disclosed first unit 110 extends downward. An exemplary pluggable alignment module 400 is equipped with a coupling module 155, as at least as referenced... Figure 1 As disclosed in the first pluggable alignment module 125. The coupling module 155 is equipped with two alignment members 415.

[0062] For example, alignment member 410, coupling module 155, and / or two alignment members 415 can be configured to be (releasably) received into corresponding mating cavities in the photoelectric unit, such that the exemplary pluggable alignment module 400 is (releasably) fixed in a (predetermined) orientation. For example, the exemplary pluggable alignment module 400 can be oriented such that electromagnetic signals emitted from transmitter 135 (e.g., laser beams, such as beam 140) are (a) orthogonal to the longitudinal axis of the photoelectric unit, and / or (b) parallel to the optical axis of the photoelectric array (e.g., transmitter and / or receiver) of the photoelectric unit. Thus, the exemplary pluggable alignment module 400 can be advantageously pluggably and releasably coupled to a desired orientation for alignment.

[0063] The coupling module 155 is also equipped with a plug module 160 (e.g., as at least refer to...). Figure 1 (As disclosed in the first pluggable alignment module 125). For example, when releasably and pluggably coupled to the optoelectronic unit, the plug module 160 can operatively electrically couple the transmitter 135 to a power source.

[0064] Figure 5 An exemplary PAM is depicted that is releasably and pluggably coupled to an exemplary light rod. The exemplary pluggable alignment system 500 includes an exemplary pluggable alignment module 400 that is pluggably and releasably coupled to a light rod 501. The light rod 501 includes an upper module 505 and a lower module 510. By way of example and not limitation, the light rod 501 may be configured as described in at least the following documents… Figure 2 A- Figure 3 As disclosed: U.S. Application No. 15 / 494,415, entitled “Field Installable Light Curtain Status Module,” filed April 21, 2017, and published on January 16, 2018, under U.S. Patent No. 9,870,681; and U.S. Application No. 14 / 819,264, entitled “Field Installable Light Curtain Status Module,” filed August 5, 2015, and published on June 6, 2017, under U.S. Patent No. 9,671,523, the entire contents of which are incorporated herein by reference.

[0065] In the depicted example, the light rod 501 is equipped with a first photoelectric array 515, which includes a (linear) array of receiver elements (e.g., optical sensors). The light rod 501 is also equipped with a second photoelectric array 520, which includes a (linear) array of emitter elements (e.g., laser emitters). As shown, the first photoelectric array 515 and the second photoelectric array 520 are oriented along a longitudinal axis 525. The longitudinal axis 525 is (substantially) parallel to the longitudinal axis 530 of the light rod 501. Each emitter of the second photoelectric array 520 is configured to emit along an optical axis parallel to an optical axis 545. The optical axis 545 may be substantially orthogonal to the longitudinal axis 525. For example, the receivers of the first photoelectric array 515 may be configured to receive along a corresponding optical axis parallel to the optical axis 545. Therefore, the optical plane may be defined, for example, by a plane comprising the longitudinal axis 525 and the optical axis 545. For example, orientation can be induced and / or maintained by coupling module 155, alignment member 410, two alignment members 415, plug module 160, or some combination thereof.

[0066] An exemplary pluggable alignment module 400 is pluggably assembled to the end of a light bar 501 along a longitudinal axis 530. The emitter 135 is thus oriented to emit along an optical axis 540. The optical axis 540 is (substantially) parallel to the optical axis 545. For example, the optical axis 540 may be in an optical plane. For example, the indicator module 150 may be configured to generate at least one visual mark in response to an irradiated optical signal within a (predetermined) range relative to the optical plane (e.g., left / right) and / or within a (predetermined) range relative to the optical axis 540 (e.g., upper / lower). For example, this range may correspond to a predetermined "proximity alignment" range.

[0067] The exemplary pluggable alignment module 400 is also equipped with a button 550. For example, button 550 may be at least part of an operator control input receiver (e.g., operator control input receiver 220, operator control input receiver 320). Button 550 may be configured to selectively activate transmitter 135. For example, operation of button 550 may toggle transmitter 135 on / off.

[0068] In various embodiments, the axial coupling of the exemplary pluggable alignment module 400 to the end of the light rod 501 can advantageously prevent obstruction of one or more elements of the first photoelectric array 515 and / or the second photoelectric array 520. For example, the light rod 501 can be a “full-length” light rod configured to generate a light curtain (e.g., light curtain 120) along substantially its entire length. Therefore, the axial coupling of the exemplary pluggable alignment module 400 to the end of the light rod 501 can advantageously allow the light rod 501 to be aligned without obstructing any portion of the first photoelectric array 515 and / or the second photoelectric array 520.

[0069] Figure 6 An exemplary PAM with an exemplary leaflet-shaped reflective module is depicted. An exemplary pluggable alignment system 600 is depicted. In the depicted example, the pluggable alignment module 601 is axially releasably and pluggably coupled to an optical rod 501. The pluggable alignment module 601 is equipped with a leaflet-shaped reflective module 605. As shown, the leaflet-shaped reflective module 605 is configured with extending regions along the + / -y direction (left-right relative to the optical plane) and along the + / -z direction (upper-lower relative to the optical axis 540). For example, the leaflet-shaped reflective module 605 can advantageously provide indication when opposing units are close to alignment in a first degree of freedom (e.g., upper / lower when the left or right lobe generates a visual mark), and even when opposing units are relatively far from alignment in a second degree of freedom (e.g., to the left or right of the top and bottom lobes).

[0070] Figure 7 An exemplary PAM with an exemplary elliptical reflective module is depicted. An exemplary pluggable alignment system 700 is depicted. In the depicted example, the pluggable alignment module 701 is axially releasable and pluggable coupled to a light rod 501. The pluggable alignment module 701 is equipped with an elliptical reflective module 705. For example, the elliptical reflective module 705 can advantageously limit the generation of visual markers to a substantially continuously variable or constant distance from the alignment target (e.g., the center of the elliptical reflective module 705).

[0071] Figure 8An exemplary PAM with an exemplary spatially separated reflector module and emitter module is depicted. An exemplary pluggable alignment system 800 is depicted. In the depicted example, a pluggable alignment module 801 is axially releasable and pluggable coupled to a light bar 501. The pluggable alignment module 801 is equipped with a rectangular reflector module 805. The pluggable alignment module 801 also includes an emitter 810 positioned above the rectangular reflector module 805. In various embodiments, by way of example and not limitation, the opposing PAM may include an indicator module positioned above the emitter. Thus, the corresponding pair of PAMs can advantageously indicate alignment without the risk of the user “losing” the alignment beam on the rectangular reflector module 805 when the corresponding pair of PAMs are perfectly aligned (e.g., by illuminating the alignment beam into the (non-reflective) aperture for the emitter 810). By offsetting the emitter 810 from the target (e.g., the center of the rectangular reflector module 805), the target point and / or area can be advantageously uninterrupted and clearly visible. In some embodiments, a visual marker of the target may be provided on the rectangular reflector module 805. As an example and not a limitation, target visual markers may include dots. Target visual markers may include crosshairs. Target visual markers may include the bullseye.

[0072] Figure 9 An exemplary PAM with an exemplary active marker generation module is depicted. An exemplary pluggable alignment system 900 is depicted. In the depicted example, the pluggable alignment module 901 is axially releasable and pluggable coupled to a light rod 501. The pluggable alignment module 901 is equipped with an elliptical reflection module, such as at least a reference... Figure 7 As disclosed in the elliptical reflective module 705. The pluggable alignment module 901 is also equipped with an active indicator module 905. For example, the active indicator module 905 can be configured to at least reference Figure 3 As disclosed in indicator module 335. For example, active indicator module 905 can (e.g., by a controller, such as at least referencing) Figure 3The disclosed controller 310 operates to emit (optical) visual markers in response to the position of the illuminating alignment beam (e.g., a laser beam from the opposing PAM). As shown, the active indicator module 905 is configured with a "plus" configuration of up, down, left, and right arrows. One or more blocks in a group can be activated, such as corresponding, for example, to the distance that the opposing PAM must rotate and / or move to align the unit. Thus, active (visual) feedback can advantageously be generated for the user. In some embodiments, auditory feedback (e.g., one or more tones corresponding to the alignment and / or misalignment (levels)) and / or tactile feedback (e.g., haptic, such as vibration) can advantageously be generated in response to alignment and / or misalignment. For example, in some embodiments, tactile feedback operating modes can be used to convey alignment and / or misalignment.

[0073] Figure 10 Depicting Figure 1 An exemplary PAM with an exemplary touch input module is described. An exemplary pluggable alignment system 1000 is depicted. In the depicted example, a first pluggable alignment module 125 is axially releasably and pluggably coupled to a light bar 501. The first pluggable alignment module 125 is equipped with a touch input and indication module 130. For example, the touch input and indication module 130 can be configured to operate a transmitter 135 in response to a user's touch input. By way of example and not limitation, a user can “tap” the touch input and indication module 130 to turn on the transmitter 135 and / or “tap” the touch input and indication module 130 to turn off the transmitter 135. Thus, a user can easily operate the transmitter 135 without having to locate a button. As shown, a button (e.g., such as button 550) is also provided. For example, this button can disable the touch input and indication module 130, thereby advantageously preventing accidental activation of the transmitter 135.

[0074] For example, the touch input and indication module 130 can be configured as an indicator module. For example, when the transmitter 135 is in a corresponding state (e.g., on), the touch input and indication module 130 can generate at least one visual marker (e.g., emitting light of a predetermined color). For example, in some embodiments, the touch input and indication module 130 can be configured to indicate an operating mode through different lighting states (e.g., on, off, stable, flashing, color sorting, or some combination thereof). For example, in some embodiments, the touch input and indication module 130 can be configured to indicate the current state of the light bar 501 (e.g., operable, activated, aligned, alarm state, warning state, safety state). For example, the first pluggable alignment module 125 can be configured to remain on the light bar 501 after proximity alignment is achieved.

[0075] In some embodiments, the touch input and indication module 130 may not be configured to receive touch input. In some embodiments, the touch input and indication module 130 may not be configured to provide indication.

[0076] Figure 11 Depicting Figure 10 An exploded view of an exemplary PAM is shown. A first pluggable alignment module 125 is depicted in this exploded view. A base module 1105 is provided. As shown, the base module 1105 is integrally formed with a coupling module 155. The base module 1105 includes a housing 1110. The housing 1110 is equipped with a cavity 1115. The walls of the cavity 1115 include alignment features 1120. For example, the alignment features 1120 may be uniformly formed with the cavity 1115 and / or the housing 1110. For example, the alignment features 1120 may be integrally formed with the cavity 1115 and / or the housing 1110 (e.g., formed from a continuous material, for example, by injection molding).

[0077] Circuit module 1125 is configured to be disposed within cavity 1115. Circuit module 1125 includes circuit board 1130 (e.g., printed circuit board (PCB)). Circuit board 1130 is equipped with alignment feature 1135. As shown, alignment feature 1135 is a cutout in circuit board 1130. Alignment feature 1135 can be configured to engage with alignment feature 1120 when circuit module 1125 is disposed within cavity 1115. Therefore, circuit board 1130 can advantageously be disposed quickly, easily, and / or repeatably in a preferred orientation.

[0078] Cavity 1115 is also equipped with an emitter aperture 1140. Emitter aperture 1140 can be configured to align with an emitter (e.g., a laser module) to allow a beam of light originating from inside cavity 1115 to pass through housing 1110 and thus be emitted from first pluggable alignment module 125. In the depicted example, emitter alignment feature 1145 is positioned directly below emitter aperture 1140. For example, emitter alignment feature 1145 can be centered on a longitudinal axis passing through the center of emitter aperture 1140, which is parallel to the longitudinal axis of first pluggable alignment module 125 (e.g., longitudinal axis 530).

[0079] As shown, transmitter alignment feature 1145 is equipped with a concave upper surface. Transmitter alignment feature 1145 can be configured to receive transmitter 1150. Transmitter 1150 is coupled to the underside of circuit module 1125. For example, transmitter 1150 can be electrically coupled (e.g., soldered) to circuit board 1130. Transmitter alignment feature 1145 can be configured to receive and support transmitter 1150 in a desired orientation.

[0080] For example, emitter alignment feature 1145 can support emitter 1150 such that the optical axis of the light beam emitted from emitter 1150 is centered relative to emitter aperture 1140. Emitter alignment feature 1145 can support emitter 1150 in an orientation substantially parallel to the optical axis (e.g., optical axis 545) of light bar 501. For example, emitter 1150 can be oriented and supported by emitter alignment feature 1145 such that the emitted light beam is emitted along optical axis 540. Emitter alignment feature 1145 can support emitter 1150 substantially orthogonal to at least one longitudinal axis (e.g., longitudinal axis 525, longitudinal axis 530) of light bar 501. For example, emitter alignment feature 1145 can support emitter 1150 such that the light beam emitted from emitter 1150 lies within the optical plane of light bar 501 (e.g., defined by longitudinal axis 525 and optical axis 545). Therefore, when the circuit module 1125 is disposed within the cavity 1115, the transmitter 1150 can be advantageously supported and / or confined in a desired configuration (e.g., including orientation). For example, various such embodiments can allow for cost-effective manufacturing and / or assembly of the housing 1110. For instance, precise indexing features can be injection molded and / or (e.g., in post-injection molding operations) machined without incurring (significant) additional costs to the light rod 501.

[0081] The circuit module 1125 is also equipped with an indicator array 1155. The indicator array 1155 is depicted as a two-dimensional array disposed on the circuit board 1130. For example, each element of the indicator array 1155 may be electrically coupled to the circuit board 1130. For example, each element of the indicator array 1155 may be a light-emitting element (e.g., an LED). For example, the indicator array 1155 may be operated by a controller (e.g., controller 310) to generate one or more (active) visual markers (e.g., via touch input and indicator module 130). For example, the indicator array 1155 may be operated to indicate the current state of the transmitter 1150 (e.g., on, off, strobing).

[0082] The touch input and indication module 130 includes a housing 1160 and a connector element 1165. For example, the connector element 1165 may be a mechanical connector. For example, the connector element 1165 may be an electrical connector (e.g., connected to at least one light-emitting element in the housing 1160, or connected to touch-sensing circuitry in the housing 1160). The connector element 1165 may be configured to cooperate with a corresponding connector element 1170 disposed on a circuit board 1130 of the circuit module 1125. For example, the connector element 1170 may be mechanically coupled to the connector element 1165. For example, the connector element 1170 may electrically couple the connector element 1165 to the circuit board 1130.

[0083] The housing 1110 is coupled to the coupling module 155. As shown, the coupling module 155 is uniformly formed with the housing 1110. For example, the coupling module 155 may be integrally formed with the housing 1110 (e.g., formed by injection molding with a continuous material). The plug module 160 is coupled to the coupling module 155. The electrical conduits in the coupling module 155 may be configured to make electrical connections between the plug module 160 and the circuit module 1125. Therefore, when the first pluggable alignment module 125 is pluggably coupled to the light rod 501, the circuit module 1125 may be in pluggable electrical communication with the light rod 501.

[0084] Figure 12 An exemplary PAM base module with an exemplary pass-through connector module is depicted. An exemplary pluggable alignment module 1200 is depicted as having a base module 1205. The base module 1205 is equipped with a coupling module 1210 (e.g., such as coupling module 155 and / or plug module 160). The pass-through connector module is at least partially disposed in the coupling module 1210. In the depicted example, a pass-through conduit 1215 extends from the coupling module 1210. For example, the pass-through conduit 1215 may be electrically connected to a plug module (e.g., such as plug module 160) and / or a circuit module (e.g., circuit module 1125) such that when the exemplary pluggable alignment module 1200 is pluggably coupled to an optoelectronic unit (e.g., such as light bar 501, first unit 110), the pass-through conduit 1215 is electrically connected to one or more circuits (e.g., power supply 225, optoarray 350) of that optoelectronic unit.

[0085] The through-line 1215 is equipped with an electrical coupler 1220. In the depicted example, the electrical coupler 1220 is a 4-pin connector. For example, the electrical coupler 1220 can be releasably and / or pluggably coupled to a second optoelectronic unit (e.g., connected optoelectronic unit 345, such as at least referenced). Figure 3(As disclosed). Therefore, the second optoelectronic unit can be electrically connected to an optoelectronic unit (e.g., light bar 501, first unit 110) to which the exemplary pluggable alignment module 1200 is pluggably coupled. For example, a power circuit (e.g., power circuit 360) and / or an optoelectronic array (e.g., optoelectronic array 355) can be electrically connected to an optoelectronic unit coupled to the exemplary pluggable alignment module 1200 (e.g., to transmit power, data). Therefore, various embodiments can advantageously provide pluggable cascading of optoelectronic units.

[0086] Figure 13 An exemplary method for alignment using at least one PAM is described. Method 1300 begins in step 1305 by manipulating a first light bar and a second light bar into (visual) pre-alignment. For example, the first light bar and the second light bar may each include an emitting photoelectric element and a receiving photoelectric element. For example, the emitting photoelectric elements may be spatially distributed in an array. For example, the receiving photoelectric elements may be spatially distributed in an array. By way of example and not limitation, the receiving photoelectric elements may be configured as active receiver elements (e.g., generating an electrical signal in response to the detection of incoming light). For example, the receiving photoelectric elements may be configured as reflective elements (e.g., passive reflective elements configured to reflect a beam of light from the emitting element of the first light bar to the receiving element of the first light bar). For example, each light bar may be equipped with an emitting element and a receiving element (e.g., a pair of light bars, each equipped with a emitting photoelectric array and a receiving photoelectric array).

[0087] As an example, and not a limitation, an installer may attach light sticks to (e.g., on the floor, on a wall, or on a device) (pre-installed) mounts. For example, an installer may align the light sticks with (e.g., markings indicating the desired orientation). For example, an installer may project a laser line between two light sticks and use his naked eye to manipulate the light sticks to (approximately) visually align them with each other.

[0088] In step 1305, the alignment unit is pluggably coupled to each light bar along its respective longitudinal axis. For example, the installer may attach the alignment unit to the light bar after step 1305. The installer may attach the alignment unit to the light bar before step 1305.

[0089] Then, in step 1310, at least one transmitter of at least the first alignment unit in the alignment unit is activated. For example, the transmitter may be activated by input from the installer. By way of example and not limitation, input from the installer may be provided by operation of button 550, operation of touch input and indicator module 130, operation of sending command signals to at least one communication module (not shown) of the alignment unit via remote control unit, or some combination thereof.

[0090] At decision point 1315, if a mark is generated on the opposing alignment unit (e.g., by reflection of light emitted from the first alignment unit onto the indicator module), method 1300 proceeds to decision point 1325. If no mark is generated on the opposing alignment unit, the installer manipulates the light bar coupled to the (emitting) first alignment unit in step 1320 until a mark is generated.

[0091] Once a generated mark is determined at decision point 1315, it is then determined at decision point 1325 (e.g., by the installer) whether the mark indicates alignment between the emission alignment unit and the opposing alignment unit. If not, the light bar coupled to the first (emission) alignment module is manipulated in step 1330 until alignment is achieved.

[0092] Once alignment is determined at decision point 1325, final alignment is performed in step 1335. As an example, and not a limitation, final alignment may include performing a precise alignment process guided by an automated alignment system of the first and / or second photoelectric rods. Once final alignment is performed in step 1335, the transmitter is deactivated in step 1340. In some embodiments, for example, method 1300 may be repeated and / or performed in parallel for at least the second photoelectric rod. For example, method 1300 may advantageously provide rapid, guided alignment of the two photoelectric units without excessive and / or frustrating "guessing" manipulation that attempts to achieve a (predetermined) alignment level suitable for alignment and / or suitable for performing the final (precise) alignment method.

[0093] Figure 14 An exemplary method for operating PAM is described. Method 1400 begins by receiving an activation signal in step 1405. As an example and not a limitation, method 1400 can be controlled by a controller (such as, for example, at least referring to...). Figure 3 The controller (as disclosed by controller 310) performs the operation. Upon receiving an activation signal, at least one transmitter (e.g., transmitter 315) is activated in step 1410. In step 1415, a receiver (e.g., receiver 330) is monitored (e.g., by controller 310). For example, the receiver's detection of an incoming electromagnetic signal (e.g., a beam of light such as a laser beam) may be monitored. Once it is determined at decision point 1420 that the receiver has detected reflected light, it is determined at decision point 1425 whether the corresponding receiver signal corresponds to the alignment of an associated alignment unit (e.g., indicating the alignment of an associated photoelectric unit).

[0094] If the receiver signal does not correspond to alignment, an alignment guidance instruction (e.g., at least one visual marker) is generated in step 1430 (e.g., by indicator module 335). For example, this instruction may be configured (e.g., by a signal configured to illuminate the optical transmitter to provide directional feedback) to guide the installer to manipulate the alignment unit (e.g., by manipulating the attached photoelectric unit) into alignment. Once it is determined at determination point 1425 that the received signal corresponds to alignment, at least one alignment instruction (e.g., a visual instruction, an auditory instruction, a tactile instruction) is generated in step 1435. The transmitter is then deactivated in step 1440.

[0095] Although various embodiments have been described with reference to the accompanying drawings, other embodiments are also possible. For example, although an exemplary system has been described with reference to the accompanying drawings, other implementations can be deployed in other industrial, scientific, medical, commercial, and / or residential applications.

[0096] In various embodiments, the indicator module (e.g., at least referring to...) Figure 1 The disclosed indicator module 150 may include a reflective material. For example, the reflective material may include a reflective foil. For example, the foil may be a die-cut reflective tape. For example, the reflective material may be configured as a cube (rearward) reflector configured to scatter an irradiated light beam (e.g., a laser beam) so that the reflected light is more visible.

[0097] For example, various embodiments can be configured such that the indicator module provides a wide viewing angle. By way of example, and not limitation, in some embodiments, the wide viewing angle can be at least 5° on either side of the axis of the irradiated beam. For example, in some embodiments, the wide viewing angle can be at least 10°. For example, the wide viewing angle can be at least 15°. For example, the wide viewing angle can be at least 20°. For example, the wide viewing angle can be at least 25°. In some embodiments, the viewing angle of the indicator module of the alignment module can be configured, for example, substantially 10°–25° relative to the optical axis of the photoelectric unit (releasably coupled) to the alignment module. In various embodiments, the wide viewing angle can advantageously enhance the visibility of the emitted beam reflected from the opposing alignment module during the alignment process. Thus, an operator can advantageously stand at one photoelectric unit and manipulate its alignment while observing the indicator module of the opposing alignment unit, without the need for a second person or to walk to the opposing alignment unit to view the reflection of the emitted beam.

[0098] In various embodiments, by way of example and not limitation, the predetermined proximity alignment range may correspond to a predetermined alignment range between two photoelectric units (e.g., light rods). For example, the proximity alignment range may include a “misaligned” range between the respective optical axes of the two units that is greater than the minimum alignment required using an automated alignment system (e.g., integrated into one or both units) and less than the user’s ability to visually align the two optical axes (e.g., by “visually” judging them to be visually straight). By way of example and not limitation, if the automated alignment system requires a misalignment of no more than 5° between the two optical axes, but the user cannot visually align them without assistance, for example, closer than about 15°, then the proximity alignment range may include at least 5° to 15°. In some implementations, by way of example and not limitation, the proximity alignment range may at least partially overlap with two other ranges (e.g., 4° to 16° in the preceding illustrative example). For example, such an implementation may advantageously ensure a smooth transition from unassisted alignment to proximity alignment to precise alignment.

[0099] In various embodiments, some bypass circuitry implementations can be controlled in response to signals from analog or digital components, which can be discrete, integrated, or a combination of each. Some embodiments may include programmable devices, programmable devices, or some combination thereof (e.g., PLA, PLD, ASIC, microcontroller, microprocessor), and may include one or more data memories (e.g., cells, registers, blocks, pages) providing single-level or multi-level digital data storage capabilities, and may be volatile, non-volatile, or some combination thereof. Some control functions can be implemented using hardware, software, firmware, or any combination thereof.

[0100] A computer program product may contain a set of instructions that, when executed by a processor device, cause the processor to perform a specified function. These functions may be performed in conjunction with a controlled device that is operatively in communication with the processor. A computer program product that may include software may be stored in a data storage device tangibly embedded in a storage medium, such as an electronic, magnetic, or rotating storage device, and may be fixed or removable (e.g., hard disk, floppy disk, thumb drive, CD, DVD).

[0101] Although an example of a portable system has been described with reference to the above figures, other implementations can be deployed in other processing applications, such as desktop and networked environments.

[0102] For example, temporary auxiliary power input can be received from a rechargeable or disposable battery, enabling use in portable or remote applications. Some embodiments may operate in conjunction with other DC voltage sources, such as 1.5V and / or 9V (nominal) batteries. Alternating current (AC) input, such as from a 50 / 60Hz power port or a portable generator, can be received via a rectifier and appropriate scaling. The supply of AC input (e.g., sine, square, or triangle wave) input may include a line frequency converter to provide voltage boost, voltage buck, and / or isolation.

[0103] While specific characteristics of the architecture have been described, performance can be improved by combining other features. For example, caching techniques (e.g., L1, L2, ...) can be used. Random access memory may be included, for example, to provide scratchpad memory and / or load executable code or parameter information stored for use during runtime operation. Other hardware and software may be provided to perform the operation, such as network or other communication using one or more protocols, wireless (e.g., infrared) communication, stored operating energy and power supply (e.g., battery), switching and / or linear power supply circuitry, software maintenance (e.g., self-testing, upgrades), etc. One or more communication interfaces may be provided to support data storage and related operations.

[0104] Some systems can be implemented as computer systems that can be used with various implementations. For example, various implementations may include digital circuits, analog circuits, computer hardware, firmware, software, or combinations thereof. Apparatus may be implemented in a computer program product tangibly embodied in an information carrier, such as a machine-readable storage device, for execution by a programmable processor; and methods may be executed by a programmable processor executing a program of instructions to perform the functions of various embodiments by manipulating input data and generating output. Various embodiments may advantageously be implemented in one or more computer programs that can be executed on a programmable system including at least one programmable processor coupled to receive data and instructions from a data storage system, at least one input device, and / or at least one output device, and to transmit data and instructions to the data storage system, at least one input device, and / or at least one output device. A computer program is a set of instructions that can be used directly or indirectly in a computer to perform a specific activity or produce a specific result. Computer programs can be written in any programming language, including compiled or interpreted languages, and can be deployed in any form, including as standalone programs or as modules, components, subroutines, or other units suitable for use in a computing environment.

[0105] As an example, suitable processors for executing instruction programs include general-purpose and special-purpose microprocessors, which can include a single processor or one or more processors in any type of computer. Typically, the processor receives instructions and data from read-only memory or random access memory, or both. The key components of a computer are the processor for executing instructions and one or more memories for storing instructions and data. Typically, a computer will also include one or more mass storage devices for storing data files, or be operatively coupled to and in communication with such mass storage devices; such devices include disks, such as internal hard disks and removable disks; magneto-optical disks; and optical disks. Suitable storage devices for tangibly embodying computer program instructions and data include all forms of non-volatile memory, including, as examples, semiconductor memory devices such as EPROM, EEPROM, and flash memory devices; disks such as internal hard disks and removable disks; magneto-optical disks; and CD-ROM and DVD-ROM discs. The processor and memory can be supplemented by or incorporated into an ASIC (Application-Specific Integrated Circuit).

[0106] In some implementations, each system can be programmed with the same or similar information and / or initialized with essentially the same information stored in volatile and / or non-volatile memory. For example, a data interface can be configured to perform automatic configuration, automatic download, and / or automatic update functions when coupled to an appropriate host device, such as a desktop computer or server.

[0107] In some implementations, one or more user interface features can be customized to perform specific functions. Various embodiments can be implemented in computer systems including graphical user interfaces and / or internet browsers. To provide interaction with the user, some implementations can be implemented on a computer having a display device for displaying information to the user (e.g., a light-emitting diode (LED), CRT (cathode ray tube), or LCD (liquid crystal display) monitor), a keyboard through which the user can provide input to the computer, and pointing devices (e.g., a mouse or trackball).

[0108] In various implementations, the system can communicate using suitable communication methods, equipment, and technologies. For example, the system can communicate with compatible devices (e.g., devices capable of transmitting data to and / or from the system) using point-to-point communication, in which messages are transmitted directly from the source to the receiver via a dedicated physical link (e.g., fiber optic link, point-to-point cabling, daisy chain). Components of the system can exchange information via analog or digital data communication of any form or medium, including packet-based messaging over a communication network. Examples of communication networks include, for example, LANs (Local Area Networks), WANs (Wide Area Networks), MANs (Metropolitan Area Networks), wireless and / or optical networks, computers and networks forming the Internet, or some combination thereof. Other implementations can transmit messages by broadcasting to all or substantially all devices coupled together by the communication network, for example, by using omnidirectional radio frequency (RF) signals. Still other implementations can transmit messages characterized by high directionality, such as RF signals transmitted using directional (i.e., narrow-beam) antennas or infrared signals that may optionally be used with focusing optics. Using appropriate interfaces and protocols, such as, by way of example but not intended to be limiting, USB 2.0, Firewire, ATA / IDE, RS-232, RS-422, RS-485, 802.11a / b / g, Wi-Fi, Ethernet, IrDA, FDDI (Fiber Distributed Data Interface), Token Ring, frequency division, time division, or code division based multiplexing techniques, or some combination thereof, other implementations are also possible. Some implementations may optionally incorporate features such as error checking and correction (ECC) for data integrity, or security measures such as encryption (e.g., WEP) and password protection.

[0109] In various embodiments, the computer system may include Internet of Things (IoT) devices. IoT devices may include objects embedded with electronic devices, software, sensors, actuators, and network connectivity that enable these objects to collect and exchange data. IoT devices can be used with wired or wireless devices by sending data to another device through an interface. IoT devices can collect useful data and then autonomously flow that data between other devices.

[0110] Various examples of modules can be implemented using circuits comprising a variety of electronic hardware. By way of example, and not limitation, the hardware may include transistors, resistors, capacitors, switches, integrated circuits, other modules, or some combination thereof. In various examples, the module may include analog logic, digital logic, discrete components, traces, and / or memory circuits fabricated on a silicon substrate, including various integrated circuits (e.g., FPGAs, ASICs), or some combination thereof. In some embodiments, the module may relate to the execution of pre-programmed instructions, software executed by a processor, or some combination thereof. For example, various modules may involve both hardware and software.

[0111] In an exemplary aspect, an alignment system may include an alignment source module configured to be releasably coupled to a first unit in a pair of photoelectric arrays, such that the alignment source module is oriented to emit a light beam substantially aligned with a first optical axis of the first unit.
