Description

SYSTEM AND APPARATUS FOR COMPLIANT QUICK CONNECTION OF LABORATORY DEVICES CROSS-REFERENCE TO RELATED APPLICATIONS

[0001] The following application claims the benefit of U.S. Provisional Appl. No.63 / 749,781, filed January 27, 2025, which is incorporated herein by reference in its entirety.BACKGROUND FIELD

[0002] Aspects of the present disclosure relate to biological processing systems and apparatuses, for example, coupling apparatuses that couple two or more laboratory devices together.BACKGROUND

[0003] Biological laboratory processing can be implemented by automated laboratory devices. However, it can be difficult to couple two or more laboratory devices together in a way that integrates them into a cohesive biological processing system.

[0004] Current lab automation designs use expensive and static coupling to integrate two or more laboratory devices into a biological processing system. For example, a specialist in lab integration can perform a one-time lab integration in which all required pieces of equipment are semi-permanently integrated. These integration methods can be insufficient for many laboratories for numerous reasons. First, the integration methods can be expensive because it can only be conducted by specialists, instead of ordinary users. Second, the existing coupling devices can be inflexible and limit a user’s ability to reconfigure previously integrated hardware. Third, it can be difficult to establish stable data communication between laboratory devices. For example, communication delays may cause different laboratory devices to fail to act in concert. Additionally, existing communication protocols, such as WiFi and many implementations of Ethernet, do not provide information about the relative positions of laboratory devices. Therefore, even when two laboratory devices have a data connection, a user manually registers the positions of the laboratory devices in software.BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The term “about” or “substantially” or “approximately” as used herein indicates the value of a given quantity that can vary based on a particular technology. Based on the particular technology, the term “about” or “substantially” or “approximately” can indicate a value of a given quantity that varies within, for example, 1-15% of the value (e.g., ±1%, ±2%, ±5%, ±10%, or ±15% of the value).Example Biological Processing System with Coupling Apparatus

[0019] Provided herein are system, apparatus, device, and / or method, and / or combinations and sub-combinations thereof, for coupling (and / or decoupling) of two or more laboratory devices (e.g., modular robotic systems) to set up a biological processing system. For example, a user may assemble various layouts for a biological processing system by simply placing laboratory devices next to each other in a mix-and-match manner. Aspects of the coupling apparatus described herein can enable mechanical and electrical connection (and / or disconnection) of laboratory devices in an easy-to-use manner. Aspects of the coupling apparatus described herein can tolerate uneven surfaces on which the laboratory devices rest, while still maintaining the connection. Aspects described herein allow forstable, high-speed communication between laboratory devices. Aspects described herein also enable a laboratory device to identify the relative locations of other laboratory devices connected to it via the coupling apparatus. This characteristic allows for automatic registration of laboratory devices, which enables the laboratory devices to pass data and / or materials between each other seamlessly.

[0020] FIG. 1 illustrates a perspective view of a biological processing system, referred to as system 100, that includes laboratory devices coupled to each other, according to some aspects. System 100 can include a plurality of laboratory devices as modular stations that contain tools and equipment for use in a given process, such as freezing or pipetting biological samples. In some aspects, system 100 can include a plurality of laboratory devices 102a, 102b and a controller 104. In the example aspect shown in FIG. 1, system 100 can be made from two modular laboratory devices (e.g., laboratory devices 102a, 102b) that are coupled to each other. An example modular laboratory device system, which may be used in and benefit from aspects described herein, is described in PCT Appl. Publ. WO 2023 / 173038, which is incorporated herein by reference in its entirety. A skilled artisan will recognize that additional modular laboratory devices may be added to system 100 in any order or location, such that each modular laboratory device is coupled to any adjacent modular laboratory device using respective coupling apparatuses as illustrated in FIGS.2A-2B.

[0021] In some aspects, each of laboratory devices 102a, 102b can perform a particular function, such as pipetting, cooling (e.g., refrigerating or freezing), centrifuging, optical inspection, or the like. Each of laboratory devices 102a, 102b can contain tools and devices needed to accomplish its function. Accordingly, each of laboratory devices 102a, 102b can include, for example and without limitation, a freezer, a refrigerator, a pipettor, an incubator, an optical analysis device, a heater, a centrifuge, a PCR machine, a sequencer, a room temperature storage module, a shaker, a gripper, a tube and tube cap manipulator, a spectrophotometer, and / or various metrology devices. In some aspects, each of laboratory devices 102a, 102b can include a robotic manipulator and a plurality of transfer deck slots. Each robotic manipulator of laboratory devices 102a, 102b can be a robotic arm with an engagement mechanism that allows the robotic arm to interact with objects within the volume of or near its respective one of laboratory devices 102a, 102b. Each robotic manipulator may be an articulable manipulator capable of movement in some or alldirections, and may be positioned anywhere on its respective one of laboratory devices 102a, 102b. The engagement mechanism may be a gripper, a magnetic mechanism, a suction mechanism, a lifter, or the like, for interaction with objects such as plates, tubes, bowls, arrays, and the like.

[0022] In some aspects, each of laboratory devices 102a, 102b can include a chassis (e.g., a frame, a support structure, etc.) that defines a volume of each of laboratory devices 102a, 102b. In the example aspect shown in FIG. 1, laboratory device 102a can include chassis 106a and laboratory device 102b can include chassis 106b, respectively. For illustrative purposes, each of chassis 106a, 106b in FIG. 1 are cut off to show other components of laboratory devices 102a, 102b. It is understood that chassis 106a, 106b may extend to form an enclosed three-dimensional shape. For example, each of chassis 106a, 106b can have a cuboid shape (e.g., cube, rectangular prism, trapezoidal prism, or the like) having a volume, such as a deck with an overhead and / or side support structure as described in PCT Appl. Publ. WO 2023 / 173038, which is incorporated by reference herein in its entirety. Chassis 106a, 106b can be configured to support the robotic manipulator of each of laboratory devices 102a, 102b, a plurality of transfer deck slots, and / or other tools used for biological processing.

[0023] In some aspects, chassis 106a, 106b can include a plurality of sides HOa-llOh. In the example aspect shown in FIG. 1, chassis 106a can include four sides HOa-llOd and chassis 106b can include four sides HOe-llOh. In this example, side 110a of chassis 106a can be located adjacent to side 1 lOe of chassis 106b so that laboratory devices 102a, 102b are in position adjacent to each other for coupling. A skilled artisan will recognize that laboratory devices 102a, 102b can be rotated relative to each other so that any one of sides 110a-l lOd is adjacent to any one of sides 110e-l lOh for coupling. In some aspects, each of sides 110a- 11 Oh can include components for coupling laboratory devices 102a, 102b together. Specifically, each of sides HOa-llOh of chassis 106a, 106b can include corresponding ones of hitches 112a-l 12h and latches 114a-l 14h, as described below. Each of the plurality of sides 110a- 11 Oh can include a door or set of doors (not shown) to protect the interior volume of each of chassis 106a, 106b, while granting selectable access to hitches 112a-112h and latches 114a-114h. While FIG. 1 illustrates hitches 112a-112h and latches 114a-l 14h at corresponding sides 110a- 11 Oh of a base of each chassis 106a, 106b, a skilled artisan will recognize that hitches 112a-112h and latches 114a-114h canalternatively be placed on any common surface (such as a side support column or an overhead support structure) accessible to neighboring laboratory devices 102a, 102b.

[0024] In some aspects, each of hitches 112a-112d on laboratory device 102a can be configured to mate with each of latches 114e-114h on laboratory device 102b when the corresponding ones of sides 110a- 11 Oh are adjacent to each other. Similarly, each of hitches 112e-l 12h on laboratory device 102b can be configured to mate with each of latches 114a- 114d on laboratory device 102a when the corresponding ones of sides HOa-llOh are adjacent to each other. Therefore, a pair of hitches 112a-l 12d and latches 114e-l 14h (and a pair of hitches 112e-112h and latches 114a-114d) can form a coupling apparatus for connecting laboratory devices 102a, 102b. For example, as shown in FIG. 1, the pair of hitch 112a and latch 114e can form the coupling apparatus for connecting laboratory devices 102a, 102b, as described in further detail below with reference to FIGS. 2A-2B. A coupling apparatus can mechanically and electrically connect laboratory devices 102a, 102b to each other.

[0025] In some aspects, each of the plurality of hitches 112a-112h can be coupled to a corresponding one of the plurality of sides 110a- 11 Oh. In some aspects, each of the plurality of latches 114a-l 14h can be coupled to a corresponding one of the plurality of sides 110a- 1 lOh and located adjacent to a corresponding one of the plurality of hitches 112a-l 12h on the same one of sides 110a-l lOh. In this configuration, the layout of hitches 112a-l 12h and latches 114a-l 14h on each of laboratory devices 102a, 102b can be rotationally symmetric. Therefore, regardless of the orientation of laboratory devices 102a, 102b relative to each other, one of hitches 112a-112h on one of laboratory devices 102a, 102b always faces one of latches 114a-l 14h on the other of laboratory devices 102a, 102b when laboratory devices 102a, 102b are located adjacent to each other. This configuration can be referred to as “symmetric coupling.” As a result of the symmetric coupling for aspects described herein, a user does not have to consider the orientation of laboratory devices 102a, 102b when setting up or reconfiguring the layout of system 100 nor whether coupling components are compatible for mating. Accordingly, the rotational symmetry of sides 110a- 11 Oh can enable the user to have a seamless experience when assembling system 100 with symmetric coupling.

[0026] In some aspects, two coupling apparatuses can be located on each of sides 1 Wall Oh to rotationally constrain the movement of laboratory devices 102a, 102b relative toeach other. In the example aspect shown in FIG. 1, one of hitches 112a-112d and one of latches 114a-114d (each including a socket) on one of sides HOa-llOd of first laboratory device 102a can be configured to mate with a corresponding one of latches 114e-l 14h (each including a socket) and a corresponding one of hitches 112e-112h on one of sides 1 Well Oh of second laboratory device 102b such that laboratory devices 102a, 102b are rotationally constrained. In this configuration, laboratory devices 102a, 102b can be locked in three degrees of freedom to prevent rotation about a vertical Z-axis and translation about a horizontal X-axis and a horizontal Y-axis. As described below with reference to FIGS.6A-6C, laboratory devices 102a, 102b can be compliant in three other degrees of freedom to enable translation about the vertical Z-axis and rotation about the horizontal X-axis and the horizontal Y-axis. Therefore, when laboratory devices 102a, 102b are coupled, they can tolerate resting on any uneven surfaces while still maintaining rigid connections to each other in certain axes.

[0027] In some aspects, during assembly of the modular system, laboratory devices 102a, 102b can be placed adjacent to each other as shown in FIG. 1. In this example aspect, a user can mate latch 114a with hitch 112e (one coupling apparatus) and latch 114e with hitch 112a (another coupling apparatus) to form the mechanical and electrical connection between laboratory devices 102a, 102b. A skilled artisan will recognize that any number of laboratory devices can be arranged in a grid-like pattern and scaled to any degree.

[0028] In some aspects, each coupling apparatus can be a standard electrical connector allowing unidirectional or bidirectional communication between laboratory devices 102a, 102b. To allow communication and cooperation between each of laboratory devices 102a, 102b in a modular laboratory assembly, a standard input / output (VO) system may be used. By using a standard I / O system, it is ensured that every device within system 100 supports modularity. Specifically, different modules within system 100, such as a freezer module and an automatic pipetting module, may be able to communicate between each other. A skilled artisan will recognize that a biological processing module may also include a custom hardware component programmed to use the standard I / O system.

[0029] In some aspects, controller 104 can be implemented on any combination of one or more processors (also called central processing units, or CPUs), memory storing control logic (i.e., computer software) and / or data, and a network. For example, controller 104 can be a laptop, desktop computer, mobile phone, tablet, or other computing device. Controller104 can communicate and interact with any combination of external devices, external networks, external entities, etc. over a wired and / or wireless communications path (which may include any combination of LANs, WANs, the Internet, etc.). Controller 104 can be implemented by and / or controlled by instructions transmitted from a central processing system, as described in PCT Appl. Publ. WO 2023 / 173038, which is incorporated by reference herein in its entirety.

[0030] In some aspects, controller 104 can be coupled to the plurality of laboratory devices 102a, 102b. Controller 104 can be configured to send command signals to each of the plurality of laboratory devices 102a, 102b via the electrical connection between the plurality of laboratory devices 102a, 102b established by at least one coupling apparatus. Controller 104 can communicate with laboratory devices 102a, 102b through a wired or wireless connection, such as Bluetooth. In some aspects, controller 104 can communicate with each of laboratory devices 102a, 102b through a network. The network can be an ad hoc network, an intranet, an extranet, a virtual private network (VPN), a local area network (LAN), a wireless LAN (WLAN), a wide area network (WAN), a wireless wide area network (WWAN), a metropolitan area network (MAN), a portion of the Internet, a portion of the Public Switched Telephone Network (PSTN), a cellular telephone network, a wireless network, a WiFi network, a WiMax network, any other type of network, or a combination of two or more such networks. Although controller 104 is shown as separate from each of laboratory devices 102a, 102b, controller 104 may alternatively be integrated into one of laboratory devices 102a, 102b, which may then be identified as a master module. Controller 104 can register the location and orientation of laboratory devices 102a, 102b. Controller 104 can provide operating instructions to one or more of laboratory devices 102a, 102b to execute a particular biological process.

[0031] FIGS. 2A-2B illustrate perspective views of a coupling apparatus 208, according to some aspects. In some aspects, coupling apparatus 208 can be configured to connect and / or disconnect first and second laboratory devices 202a, 202b. FIG. 2A illustrates coupling apparatus 208 in an “unlatched” or “decoupled” state. FIG. 2B illustrates coupling apparatus 208 in a “latched” or “coupled” state. In some aspects, coupling apparatus 208 can include a hitch 212 and a latch 214.

[0032] In some aspects, hitch 212 can be coupled to first laboratory device 202a. Hitch 212 can be located above a hole in a chassis (e.g., chassis 106a) of first laboratory device 202ato receive cabling or wiring from underneath first laboratory device 202a. Specifically, hitch 212 can be mounted at or near an edge of a side (e.g., sides 110a-l lOd) of the chassis of first laboratory device 202a. Hitch 212 can have a base portion that is fastened to first laboratory device 202a. For example, hitch 212 can be fastened to first laboratory device 202a in various configurations with fasteners such as, for example, bolts, screws, pins, adhesive, magnets, clips, rotatable cams, or the like. In some aspects, hitch 212 can be made from a magnetic material such as, for example, a ferromagnetic material.

[0033] In some aspects, hitch 212 can have a protrusion 224 that extends from the base portion fastened to laboratory device 202a. Protrusion 224 can have a substantially spherical shape, such that hitch 212 may be referred to as a “ball hitch” with a substantially spherical shape. Protrusion 224 can include an opening 213 running through protrusion 224. Opening 213 can have a cross-section of any polygonal shape, such as a quadrilateral or a circle. The size of opening 213 can vary across the height of protrusion 224 to accommodate any electrical components, circuitry, wiring, or the like that are installed within hitch 212. For example, hitch 212 can include a first connector 216.

[0034] In some aspects, first connector 216 can be embedded on or within opening 213. In some aspects, first connector 216 is inlaid within protrusion 224 yet exposed via an upper portion of protrusion 224. First connector 216 can be any kind of electrical connector such as, for example, a physical connector, an optical connector, an electromagnetic connector, or the like, as described below with reference to FIGS. 3 A-3C. In the example aspect shown in FIG. 2 A, first connector 216 can be a plurality of targets configured to receive pogo pins.

[0035] In some aspects, latch 214 can be coupled to second laboratory device 202b. Latch 214 can be substantially hollow and can be located above a hole in a chassis (e.g., chassis 106b) of second laboratory device 202b to receive cabling or wiring from underneath second laboratory device 202b. Specifically, latch 214 can be mounted at or near an edge of a side (e.g., sides 110e-l lOh) of the chassis of second laboratory device 202b. Latch 214 can have a base portion that is fastened to second laboratory device 202b. For example, latch 214 can be fastened to second laboratory device 202b in various configurations with fasteners such as, for example, bolts, screws, pins, adhesive, magnets, clips, rotatable cams, or the like. Latch 214 can include a socket 218, a hinge 222, and a fastener 238.

[0036] In some aspects, socket 218 can be located at a first end of latch 214. Socket 218 can be a hollow recess in the body of latch 214. Accordingly, socket 218 can be configuredto mate with hitch 212. As shown in the unlatched state of coupling apparatus 208 in FIG.2 A, socket 218 and hitch 212 can have a complementary size and shape. Specifically, socket 218 can be a substantially spherical recess with a circular cross-section. The size of socket 218 can vary across the height of the body of latch 214. As shown in the latched state of coupling apparatus 208 in FIG. 2B, when the first end of latch 214 is lowered onto hitch 212, hitch 212 can be fully or partially enveloped by socket 218. Once mated, socket 218 can be configured to shift relative to protrusion 224 with a degree of tolerance to allow for misalignments in certain axes. Socket 218 can be configured to include a second connector 220 for interacting with first connector 216 when socket 218 and hitch 212 are mated.

[0037] In some aspects, second connector 220 can be disposed within socket 218. Second connector 220 can be located at an interior portion of the first end of latch 214 and exposed via socket 218. In this configuration, second connector 220 can engage with the upper portion of protrusion 224 of hitch 212. Specifically, second connector 220 can be configured to mate with first connector 216 of hitch 212. Second connector 220 can be any kind of electrical connector such as, for example, a physical connector, an optical connector, an electromagnetic connector, or the like, as described below with reference to FIGS. 4A-4C. In the example aspect shown in FIG. 2 A, second connector 220 can be a plurality of pogo pins. Accordingly, when second connector 220 mates with first connector 216, second connector 220 can form an electrical connection configured to transmit data between first and second laboratory devices 202a, 202b, as described further with reference to FIGS. 5 and 7.

[0038] In some aspects, hinge 222 can be located at a second end of latch 214. Hinge 222 can couple the body of latch 214 to second laboratory device 202b. For example, hinge 222 can form the base portion of latch 214 that is fastened to a corresponding one of the plurality of sides of second laboratory device 202b. Hinge 222 can be fastened to second laboratory device 202b in various configurations with fasteners such as, for example, bolts, screws, pins, adhesive, magnets, clips, rotatable cams, or the like. Hinge 222 can be fastened to the second end of the body of latch 214 in various configurations with fasteners such as, for example, bolts, screws, pins, adhesive, magnets, clips, rotatable cams, or the like. Accordingly, hinge 222 can enable latch 214 to rotate around an axis. Specifically, hinge 222 can be configured to enable the first end of latch 214 including socket 218 to movetoward (e.g., via a lowering motion) or away from (e.g., via a lifting motion) hitch 212. As shown in FIG. 2B, hinge 222 can enable latch 214 to be moved toward hitch 212 via lowering motion 225 into a coupled position. As shown in FIG. 2A, hinge 222 can enable latch 214 to be moved away from hitch 212 with a lifting motion 223 into a decoupled position. Hinge 222 can provide a user with a simple interface for connecting and / or disconnecting laboratory devices 202a, 202b because it is only a single moving part. As a result, hinge 222 can reduce a part count, cost, and tolerances as compared to existing coupling devices.

[0039] In some aspects, fastener 238 can be located on or within the body of latch 214.Fastener 238 can be located at the first end of latch 214 and adjacent to socket 218. In the example aspect shown in FIGS. 2A-2B, fastener 238 can be embedded within latch 214 around socket 218. In this configuration, fastener 238 can have a ring shape, but it is understood that fastener 238 can have any other shape. As shown in FIG. 2B, fastener 238 can be configured to secure latch 214 to hitch 212 with a retention force 240 when mated. Accordingly, fastener 238 can be any type of fastening device (e.g., a magnetic fastener, a mechanical fastener, etc.) configured to secure protrusion 224 of hitch 212. For example, fastener 238 can be a magnet configured to attract the magnetic material of hitch 212 with the retention force 240. In another example, fastener 238 can be a deformable wire clip configured to bend around the shape of protrusion 224 of hitch 212 and hold onto protrusion 224 with retention force 240.

[0040] In some aspects, retention force 240 can secure latch 214 to hitch 212. Retention force 240 of latch 214 can have a sufficiently high magnitude to substantially maintain the position of latch 214 relative to hitch 212, regardless of whether one or both laboratory device 202a, 202b is bumped and / or perturbed. In this configuration, even a small retention force 240 can be sufficient to constrain laboratory device 202a, 202b because latch 214 would have to completely yield and fail before allowing undesired movement in the direction of retention force 240.

[0041] In some aspects, retention force 240 can assist with forming the electrical connection between first connector 216 and second connector 220. For example, retention force 240 can ensure that latch 214 remains close enough to hitch 212 so that first connector 216 and second connector 220 can interact. For example, in the configuration in which first connector 216 includes a plurality of targets and second connector 220 includes a pluralityof pogo pins, retention force 240 can have a magnitude that overcomes a combined spring force of the pogo pins at the maximum extension such that the pogo pins compress. By compressing the plurality of pogo pins of second connector 220 against the plurality of targets of first connector 216, the electrical connection can be established. This characteristic is beneficial because the electrical connection can be established without any excessive force applied by a user, thereby avoiding potential damage. Additionally, retention force 240 can ensure that latch 214 substantially remains in place relative to hitch 212 so that the electrical connection is undisturbed regardless of positional shifts when one or both laboratory device 202a, 202b is bumped and / or perturbed.

[0042] In some aspects, retention force 240 can be overcome by a disconnection force. The disconnection force may have a low magnitude (e.g., ~10N), so that latch 214 is easily operable by hand. Therefore, a user can manually apply a disconnection force to decouple laboratory devices 202a, 202b from each other. This characteristic provides an improved user experience because fastener 238 (e.g., a magnet) is easier to use for coupling / decoupling functions, as compared to complex mechanical actuation or latching mechanisms of existing coupling devices.

[0043] FIGS. 3 A-3C illustrate top views of various examples of a hitch, according to some aspects. It is understood that the various aspects of hitches described herein can be used as alternative designs to each other.

[0044] FIG. 3 A shows a hitch 312 that has a first connector 316 including a plurality of targets 326. The plurality of targets 326 can be disposed within protrusion 324 and exposed at an upper portion of protrusion 324. The plurality of targets 326 can be flat targets or slightly indented or concave targets that serve as mating surfaces for corresponding pogo pin connectors or the like on a latch (e.g. latch 414 as shown in and described below with reference to FIG. 4A). The pogo pin connectors can establish an electrical connection upon being compressed against the plurality of targets 326. Additionally, using flat or slightly indented or concave targets 326 can result in an increased tolerance for positioning of a latch relative to hitch 312 while still establishing the electrical connection, as compared to precisely matching holes into which pins would have to be inserted. Therefore, the plurality of targets 326 can enable a latch to easily connect to hitch 312.

[0045] While FIG. 3 A illustrates a plurality of targets 326, a skilled artisan would recognize that other coupling mechanisms may be used to electrically connect a latch and hitch. Forexample, FIG. 3B shows a hitch 312’ that has a first connector 316 including an optical transmitter 328. In another example, FIG. 3C shows a hitch 312” that has a first connector 316 including an induction coil 330.

[0046] As shown in the example aspect of FIG. 3B, first connector 316 of hitch 312’ can include optical transmitter 328 configured to emit radiation. Optical transmitter 328 can be disposed within protrusion 324 and exposed at an upper portion of protrusion 324. Optical transmitter 328 can be any type of light source such as, for example, a light-emitting diode (LED). Optical transmitter 328 can be configured to emit radiation in ultraviolet, visible, and / or infrared spectra. Optical transmitter 328 can be configured to interact with an optical sensor on a latch (e.g., latch 414’ as shown in and described below with reference to FIG.4B) such that the optical sensor forms an electrical connection.

[0047] As shown in the example aspect of FIG. 3C, first connector 316 of hitch 312” can include induction coil 330 that is a medium for a flow of electrical current. Induction coil 330 can be disposed within protrusion 324 and exposed at an upper portion of protrusion 324. Induction coil 330 can be configured to interact with a magnetic core on a latch (e.g., latch 414” as shown in and described below with reference to FIG. 4C) such that the magnetic core forms an electrical connection.

[0048] FIGS.4A-4C illustrate side views of various examples of a latch in an open position, according to some aspects. It is understood that the various aspects of latches described herein can be used as alternative designs to each other.

[0049] FIG. 4 A shows a latch 414 that has a second connector 420 including a plurality of pogo pins 432. The plurality of pogo pins 432 can be disposed within socket 418 and exposed via socket 418. The plurality of pogo pins 432 can be configured to contact corresponding ones of the plurality of targets 326 on hitch 312 (as shown in and described with reference to FIG. 3A) and form an electrical connection upon being compressed against the plurality of targets 326. As a result of this configuration, the plurality of pogo pins 432 can be configured to establish the electrical connection between latch 414 and hitch 312 without any excessive force applied by a user. Accordingly, the plurality of pogo pins 432 can enable a latch 414 to connect to hitch 312 with a reduced risk of damage by avoiding the use of undesirable forces applied to the components.

[0050] While FIG. 4A illustrates a plurality of pogo pins 432, a skilled artisan would recognize that other coupling mechanisms may be used to electrically connect a latch andhitch. For example, FIG. 4B shows a latch 414’ that has a second connector 420 including an optical sensor 434. In another example, FIG. 4C shows a latch 414” that has a second connector 420 including a magnetic core 436.

[0051] As shown in the example aspect of FIG. 4B, second connector 420 of latch 414’ can include optical sensor 434 configured to detect the radiation emitted by optical transmitter 328 of hitch 312’ (as shown in and described with reference to FIG. 3B). Optical sensor 434 can be disposed within socket 418 and exposed via socket 418. Optical transmitter 328 can be any type of sensor that is sensitive to light such as, for example, a photodiode. Optical sensor 434 can be configured to detect radiation in ultraviolet, visible, and / or infrared spectra. Optical sensor 434 can be configured to convert the detected radiation into electrical signals to form an electrical connection between latch 414’ and hitch 312’.

[0052] As shown in the example aspect of FIG. 4C, second connector 316 of latch 414” can include magnetic core 436 configured to be located adjacent to induction coil 330 of hitch 312” (as shown in and described with reference to FIG. 3C). Magnetic core 436 can be configured to generate a magnetic field that, when the magnetic core 436 is moved near induction coil 330, induces an electromotive force within induction coil 330 that causes a current to flow in induction coil 330. As a result, the positioning of magnetic core 436 relative to induction coil 330 can establish an electrical connection between latch 414” and hitch 312”.

[0053] With respect to the aspects described with reference to FIGS. 3 A-3C and 4A-4C, a skilled artisan will recognize that the electrical connectors on corresponding pairs of hitches 312-312” and latches 414-414” can be interchangeable. For example, hitch 312 can include a plurality of pogo pins and latch 414 can include a plurality of targets. In another example, hitch 312’ can include an optical sensor and latch 414’ can include an optical transmitter. In another example, hitch 312” can include a magnetic core and latch 414” can include an induction coil.

[0054] FIG. 5 illustrates a cross-section view of a coupling apparatus 508 forming an electrical connection 541 between first and second laboratory devices 502a, 502b, according to some aspects.

[0055] In some aspects, fastener 538 can be configured to secure latch 514 to hitch 512 with a retention force 540 when mated. In this configuration, first connector 516 of hitch 512 and second connector 520 can establish electrical connection 541 via physical orwireless connection techniques to transmit data between laboratory devices 502a, 502b. Electrical connection 541 can transmit data between laboratory devices 502a, 502b with low latency.

[0056] In some aspects, first connector 516 can be disposed within opening 513 of hitch 512. First connector 516 can be connected to a circuit board 544a located underneath first laboratory device 502a. First connector 516 can be connected to circuit board 544a via wires 542 (e.g., flexible ribbon cables) running through a hole 543a in the chassis (e.g., chassis 106a) of first laboratory device 502a. It is understood that there may be other electrical components disposed within opening 513 of hitch 512.

[0057] In some aspects, second connector 520 can be disposed within a socket of latch 514.Second connector 520 can be connected to a circuit board 544b located underneath second laboratory device 502b. Second connector 520 can be connected to circuit board 544b via wires 542 (e.g., flexible ribbon cables) running through a hole 543b in the chassis (e.g., chassis 106b) of second laboratory device 502b. It is understood that there may be other electrical components disposed within the body of latch 514.

[0058] In some aspects, circuit boards 544a, 544b can be attached to respective ones of laboratory devices 502a, 502b. For example, circuit boards 544a, 544b can be mounted on a bottom surface or a side surface on the underside of the corresponding chassis for laboratory devices 502a, 502b. In the example aspect shown in FIG. 5, circuit boards 544a, 544b are attached to a bottom surface of the underside of corresponding chassis for laboratory devices 502a, 502b. Circuit boards 544a, 544b can be attached to respective ones of laboratory devices 502a, 502b via fasteners such as, for example, screws, clips, clamps, adhesives, or the like.

[0059] In some aspects, each of circuit boards 544a, 544b can be connected to controller 504. For example, each of circuit boards 544a, 544b can be connected to controller 504 using wires that operate according to Ethernet protocols. Accordingly, circuit boards 544a, 544b can be configured to receive data from and transmit data to controller 504. Each of circuit boards 544a, 544b contains identifier information about its respective laboratory device 502a, 502b. For example, each of circuit boards 544a, 544b can be assigned an identifier tag that indicates on which side (e.g., sides 110a-l lOh) of laboratory device 502a, 502b the corresponding one of circuit boards 544a, 544b is located. In some aspects, each of circuit boards 544a, 544b may be able to provide operation instructions to electro-mechanical components on the respective laboratory device 502a, 502b and / or gather information on operations being performed at the respective laboratory device 502a, 502b. Each of circuit boards 544a, 544b can be coupled to its respective first connector 516 and second connector 520 for coupling laboratory devices 502a, 502b and exchanging data (e.g., handshake information) between them once electrical connection 541 is established.

[0060] In some aspects, when laboratory device 502a is coupled to laboratory device 502b via coupling apparatus 508, each of circuit boards 544a, 544b can send information to controller 504 about their respective laboratory devices 502a, 502b and their relative position to each other. In some aspects, one of circuit boards 544a, 544b can send information to controller 504 via the other of circuit boards 544a, 544b. Circuit boards 544a, 544b may also send calibration details regarding the functional components located on their respective laboratory devices 502a, 502b. Controller 504 can use this information to register laboratory devices 502a, 502b and identify their functional capabilities and assemble a virtual map of the biological processing system (e.g., system 100). Additionally, controller 504 can send command signals to laboratory devices 502a, 502b via its communication with circuit boards 544a, 544b. In this configuration, controller 504 can provide laboratory devices 502a, 502b with instructions for various biological processing operations.

[0061] FIGS. 6A-6C illustrate examples of cross-section views of misalignments that a coupling apparatus 608 can tolerate, according to some aspects. In some aspects, adjacent laboratory devices 602a, 602b may not have their surface datums at a planar level. Accordingly, latch 614 can be configured to shift relative to hitch 612 such that coupling apparatus 608 is able to tolerate deviations in height and / or angle. Specifically, hitch 612 and a socket of latch 614 are sized and shaped to tolerate at least one of a height misalignment, an angular misalignment, or a torsional misalignment between laboratory devices 602a, 602b.

[0062] As shown in FIG. 6 A, hitch 612 and the socket of latch 614 can be sized and shaped to tolerate a height misalignment 648. In this example aspect, a surface datum of first laboratory device 602a can be located at a first height 646a and a surface datum of second laboratory device 602b can be located at a second height 646b. Second height 646b can be higher than first height 646a, thereby resulting in height misalignment 648 between laboratory devices 602a, 602b. Due to the substantially spherical shape of hitch 612 andthe substantially spherical recess of the socket of latch 614, the first end of latch 614 can shift downward toward first height 646a to accommodate the deviation caused by height misalignment 648. Regardless of the shift, first connector 616 and second connector 620 can remain in communication to maintain an electrical and / or optical connection between laboratory devices 602a, 602b despite height misalignment 648.

[0063] As shown in FIG. 6B, hitch 612 and the socket of latch 614 can be sized and shaped to tolerate an angular misalignment 652. In this example aspect, a surface datum of first laboratory device 602a can have a first tilt 650a and a surface datum of second laboratory device 602b can have a second tilt 650b. The angular difference between first and second tilts 650a, 650b can define angular misalignment 652 between laboratory devices 602a, 602b. Due to the substantially spherical shape of hitch 612 and the substantially spherical recess of the socket of latch 614, latch 614 and hitch 612 can shift relative to each other to accommodate the deviation caused by angular misalignment 652. Regardless of the shift, first connector 616 and second connector 620 can remain in communication to maintain an electrical and / or optical connection between laboratory devices 602a, 602b despite angular misalignment 652.

[0064] As shown in FIG. 6C, coupling apparatuses 608a, 608b can operate together to tolerate a torsional misalignment 654. Specifically, hitch 612a and the socket of latch 614e (of coupling apparatus 608a) can be sized and shaped to tolerate torsional misalignment 654. Additionally, a hitch and the socket of latch 614a of coupling apparatus 608b (neither are fully shown for illustration purposes) can be sized and shaped to tolerate torsional misalignment 654. In this example aspect, a first surface datum of first laboratory device 602a can be located at a first height 646a and a second surface datum of first laboratory device 602a can be located at a third height 646c. A surface datum of second laboratory device 602b can be located at a second height 646b in between first and third heights 646a, 646c. In this configuration, first laboratory device 602a is “twisted” relative to second laboratory device 602b, thereby resulting in torsional misalignment 654 between laboratory devices 602a, 602b. Due to the substantially spherical shape of hitch 612a and the substantially spherical recess of the socket of latch 614e, the first end of latch 614e can shift downward toward first height 646a to accommodate the deviation caused by torsional misalignment 654. Additionally, due to the substantially spherical shape of the hitch of coupling apparatus 602b and the substantially spherical recess of the socket of latch 614a,the first end of latch 614a can shift downward toward second height 646b to accommodate the deviation caused by torsional misalignment 654. Regardless of the shift, first connector 616 and second connector 620 of coupling apparatus 608a and those of coupling apparatus 608b can remain in communication to maintain electrical connections between laboratory devices 602a, 602b despite torsional misalignment 654.

[0065] Accordingly, in some aspects, coupling apparatus 608 can enable flexibility in three degrees of freedom to account for relative changes in height, tilt, and torsion between laboratory devices 602a, 602b. Meanwhile, coupling apparatus 608 can maintain rigidity in three other degrees of freedom so that laboratory devices 602a, 602b are rotationally constrained. Therefore, as compared to existing methods for trueing the relative positions of equipment into an aligned position, coupling apparatus 608 can provide an improved user experience by enabling a user to connect laboratory devices 602a, 602b regardless of the uneven surfaces on which laboratory devices 602a, 602b rest.

[0066] FIG. 7 illustrates a schematic diagram of data signals 756 flowing through a system 700 of laboratory devices 702a-702f via coupling apparatuses 708a-7081, according to some aspects.

[0067] In some aspects, each of laboratory devices 702a-702f can configured to transmit data signals 756 for positional registration as system 700 is assembled. For example, once each of laboratory devices 702a-702f is connected to power, they can send data signals 756 via coupling apparatuses 708a-7081 about their status, location, and orientation to each other and controller 704. The electrical connection at each of coupling apparatuses 708a- 7081 can transmit data signals 756 unidirectionally or bidirectionally. Controller 704 can use the information conveyed by data signals 756 to register laboratory devices 702a-702f and identify their functional capabilities and orientations in order to assemble a virtual map of system 700. Once all of laboratory devices 702a-702f have been coupled together, controller 704 can complete its virtual map (e.g., graph) of the spatial relationship between all the components, along with their individual functionalities. For example, system 700 can have a coordinate system determined by the orientation of the assembled modules.

[0068] In one example aspect, laboratory device 702a can notify controller 704 that it is a freezer module. Laboratory device 702a can further notify central controller 402 that it is coupled to laboratory device 702b, an incubator module, on its east side. Similarly, laboratory device 702b can notify controller 704 that it is an incubator module. Laboratorydevice 702b can further notify controller 704 that it is coupled to laboratory device 702a, a freezer module, on its west side. From this information, controller 704 can determine the spatial orientations of and relationship between laboratory devices 702a, 702b. Controller 704 can then link laboratory devices 702a, 702b in the virtual map. Each of laboratory devices 702a-702f and controller 704 can transmit such identifying information to each other until the entire system 700 is mapped.

[0069] In some aspects, data signals 756 can be transmitted according to certain communication protocols. In some aspects, data signals 756 can include communication data and positional data related to the plurality of laboratory devices 702a-702f. In this configuration, the communication data can be transmitted between the plurality of laboratory devices 702a-702f based on Ethernet communication protocols. In this configuration, the positional data can be transmitted between the plurality of laboratory devices 702a-702f based on RS-485 communication protocols. As a result, the plurality of laboratory devices 702a-702f can operate via high-bandwidth and stable communication. In some aspects, controller 704 can be configured to apply a minimum spanning tree protocol to eliminate signal loops of the communication data between the plurality of laboratory devices 702a-702f. For example, controller 704 may artificially disconnect communications at coupling apparatuses 708e, 708f to prevent signal loops between laboratory devices 702b-702e while still keeping all of laboratory devices 702a-702f in communication.

[0070] In some aspects in which the plurality of laboratory devices 702a-702f are configured to communicate via a wireless network, data signals 756 can include positional data related to the plurality of laboratory devices 702a-702f and wireless connection credentials. In this configuration, the positional data and the wireless connection credentials can be transmitted between the plurality of laboratory devices 702a-702f based on, e.g., RS-485 communication protocols. Once the plurality of laboratory devices 702a-702f have received the wireless connection credentials, they can access the wireless network (e.g., WiFi) for high-bandwidth communication.

[0071] FIG. 8 illustrates a method 860 for connecting first and second laboratory devices, according to some aspects.

[0072] In some aspects, at step 862, a latch can be moved, via a hinge of the latch coupled to the first laboratory device, toward a hitch coupled to the second laboratory device when the first laboratory device is adjacent the second laboratory device.

[0073] In some aspects, at step 864, an electrical connection can be formed between the first and second laboratory devices by mating a first connector, disposed within the hitch, with a second connector disposed within a socket of the latch.

[0074] In some aspects, the first connector can include a plurality of targets and the second connector can include a plurality of pogo pins. In this configuration, forming the electrical connection can include compressing the plurality of pogo pins of the second connector against the plurality of targets of the first connector.

[0075] In some aspects, forming the electrical connection can include emitting radiation from the first connector comprising an optical transmitter, detecting the radiation with the second connector comprising an optical sensor, and generating electrical signals from the second connector to transmit between the first and second laboratory devices.

[0076] In some aspects, the first connector can include an induction coil and the second connector can include a magnetic core. In this configuration, forming the electrical connection can include running a current through the induction coil of the first connector when the magnetic core of the second connector is located adjacent to the induction coil.

[0077] In some aspects, at step 866, the latch can be fastened to the hitch with a retention force.

[0078] In some aspects, the hitch can include a magnetic material and the fastener can include a magnet located at the first end of the latch and adjacent to the socket. In this configuration, fastening the latch to the hinge can include attracting the magnetic material of the hitch with retention force from the magnet of the latch. In some aspects, step 866 may occur simultaneously or near simultaneously with step 864.

[0079] In some aspects, at step 868, data can be transmitted between the first and second laboratory devices via the electrical connection.

[0080] In some aspects, transmitting data can include transmitting communication data and positional data related to the first and second laboratory devices. In this configuration, the communication data can be transmitted based on Ethernet communication protocols. In this configuration, the positional data related to the first and second laboratory devices can be transmitted based on, e.g., RS-485 communication protocols.

[0081] In some aspects, transmitting data can include transmitting positional data related to the first and second laboratory devices and wireless connection credentials. In this configuration, the positional data and the wireless connection credentials can be transmitted based on, e.g., RS-485 communication protocols.

[0082] The method steps of FIG. 8 can be performed in any reasonable order and it is not required that all steps be performed. Moreover, the method steps of FIG. 8 described above merely reflect an example of steps and are not limiting. That is, further method steps and functions are envisaged based on aspects described in reference to FIGS. 1-7.
