[0035] Example embodiments will be described more fully hereinafter with reference to the accompanying drawings, which illustrate some, but not all, embodiments of the disclosed invention. Indeed, embodiments of the disclosed invention may be embodied in many different forms and should not be construed as limited to the embodiments set forth herein; rather, these embodiments are provided so that this disclosure will satisfy applicable legal requirements. Like numbers refer to like elements throughout.
[0036] Various example embodiments address technical issues associated with exchanging data in rotating electrical connectors, such as slip ring connectors. As those skilled in the art will appreciate, there are many example scenarios in which a user may need to exchange data between computing devices via rotating electrical connectors.
[0037] Rotating electrical connectors enable the transfer of power and / or data between stationary and rotating electrical components. Numerous technologies exist that could benefit from the use of rotating electrical connectors. Examples include industrial machinery, robotics, wind turbines, cameras, remote sensing devices (e.g., radar, lidar sensors), and / or other similar electromechanical devices. As a specific example, a security camera may include a fixed base mounted on a surface and an imaging device comprising a lens and optical sensor capable of rotation and / or yaw, pitch, and roll movement. One approach that has been used to provide electrical connectivity between stationary and rotating computing devices is to maintain a physical or mechanical connection between the two computing devices. This physical or mechanical connection can be maintained by electrically connecting the rotating computing device to one or a series of rotating conductive disks (e.g., a rotor). Furthermore, the stationary computing device can be electrically connected to one or a series of conductive pins that are in electrical contact with the rotating conductive disk (e.g., a stator). This approach allows the conductive disk to rotate while the conductive pins maintain contact with the disk. However, over time, the performance of the conductive pins that slide on the conductive disk may degrade. Furthermore, in some instances, the conductive pins may lose contact with the disk. Over time, electrical connections can weaken and data transmission can become unreliable, especially at high frequencies.
[0038] Another approach to data transmission in rotating electrical connectors is to use optical signals. In this embodiment, optical signals are transmitted by a fixed transceiver in the rotating electrical connector and received by a rotating optical transceiver, and vice versa. However, such rotating electrical connectors can experience significant losses, resulting in signal degradation, primarily due to angular and axial misalignment.
[0039] Various example embodiments described herein utilize various techniques for transmitting data within a rotating electrical connector. For example, in some embodiments, a stationary computing device can be electrically connected to a fixed wireless transceiver attached to a stator within the connector housing. Furthermore, a rotating computing device can be electrically connected to a rotating wireless transceiver attached to a rotor also within the connector housing. The fixed wireless transceiver and the rotating wireless transceiver can be directed toward each other, with a certain distance between the two wireless transceivers. Data transmitted from the stationary computing device to the rotating computing device can be transmitted from the stationary computing device to the fixed wireless transceiver. The data can then be transmitted by the fixed wireless transceiver and received by the rotating wireless transceiver electrically connected to the rotating computing device. Similarly, data transmitted from the rotating computing device to the stationary computing device can be transmitted by the rotating wireless transceiver and received by the fixed wireless transceiver electrically connected to the stationary computing device. Communication achieved through the fixed wireless transceiver and the rotating wireless transceiver can allow the rotating computing device to rotate continuously without causing strain or wear on the mechanical electrical contacts.
[0040] To support higher data rates (e.g., data rates greater than 100 megabits per second), in some embodiments, the wireless transceiver may include components operating at frequencies between 30 GHz (10 mm wavelength) and 300 GHz (1 mm wavelength), capable of transmitting data at rates between 100 megabits per second and 10 gigabits per second. Additionally, the wireless transceiver may include an antenna capable of transmitting circularly polarized waves, enabling high-speed data transmission and reception regardless of the rotational relationship between the transmitting and receiving wireless transceivers.
[0041] Furthermore, in some embodiments, the rotating electrical connector may include a mechanical slip ring connection for physical connection. The mechanical slip ring connection may be utilized to transmit power and data transmitted at a lower frequency. Transmitting power using a mechanical slip ring connection may provide more efficient power transmission than transmitting power wirelessly.
[0042] Due to the example embodiments described herein and in some examples, the reliability of high-speed data transmission in rotating electrical connectors can be significantly improved. In addition, in some embodiments, low data rate data and power can continue to be transmitted through the mechanical slip ring connection.
[0043] Now see Figure 1 , an example prior art slip ring connector 100 is provided that electrically connects to a stationary computing device 102 and a rotating computing device 104. Figure 1 As depicted in , the example slip ring connector 100 includes a rotating portion (e.g., a rotor portion 114) that is permitted to rotate within a stationary portion (e.g., a stator portion 116). The rotor portion 114 also includes a plurality of conductive rings 112 that are attached to the rotor portion 114 and surround the exterior of the rotor portion 114. The conductive rings 112 are configured to rotate as the rotor portion 114 rotates within the stator portion 116 of the slip ring connector 100. Each conductive ring 112 is electrically connected to a wire of a rotating wired connection 106, wherein the rotating wired connection 106 provides an electrical connection between the conductive ring 112 and the rotating computing device 104. In instances where the rotating computing device 104 rotates, the rotating wired connection 106, the rotor portion 114, and the conductive rings 112 all rotate synchronously. As shown Figure 1As further depicted, slip ring connector 100 also includes a brush block 118 that is attached to stationary stator portion 116 and extends beyond at least a portion of rotor portion 114. A plurality of conductive pins 110, or brushes, are attached to brush block 118. Each conductive pin 110 extends from brush block 118 and contacts one of a plurality of conductive rings 112. Each conductive pin 110 is also electrically connected to a wire of a fixed wired connection 108, which provides an electrical connection between the conductive pins 110 and stationary computing device 102. In instances where rotating computing device 104 and rotor portion 114 rotate, conductive pins 110 slide on the surface of conductive ring 112, thereby maintaining an electrical connection between stationary computing device 102 and rotating computing device 104 via fixed wired connection 108 and rotating wired connection 106.
[0044] As described herein, the connection between the conductive ring 112 and the conductive pins 110 may become unstable or deformed. In such instances, the electrical connection may become unreliable, such that data transmitted between the stationary computing device 102 and the rotating computing device 104 may be partially or completely lost. Unreliable electrical connections are particularly problematic for data transmitted at higher frequencies and / or higher data rates.
[0045] like Figure 1 As depicted in FIG, an example slip ring connector 100 provides a physical electrical connection between a stationary computing device 102 and a rotating computing device 104. The stationary computing device 102 can be any machine or device including hardware, software, firmware, and / or a combination thereof, and configured to execute instructions and / or hard-coded functionality to perform operations defined by the particular device. Additionally, the stationary computing device 102 can be attached and / or fixed relative to the rotating computing device 104 such that the stationary computing device 102, the stator portion 116, the brush block 118, and the conductive pins 110 remain stationary while the rotor portion 114 rotates within the stator portion 116. For example, the stationary computing device 102 can be a controller within a base of a security camera. Although primarily depicted as being stationary, in some embodiments, the stationary computing device 102 can also rotate, move, and / or otherwise change position relative to the slip ring connector 100.
[0046] like Figure 1As further depicted in FIG, the slip ring connector 100 is electrically connected to a rotating computing device 104. The rotating computing device 104 can be any machine, circuit board, chip, or device including hardware, software, firmware, and / or a combination thereof, configured to receive electrical signals and execute instructions and / or hard-coded functionality to perform operations defined by the specific device. Additionally, the rotating computing device 104 can be configured to rotate relative to the stationary computing device 102. In some embodiments, the rotor portion 114 of the slip ring connector 100 can rotate with the rotating computing device 104, such that the rotor portion 114 remains stationary relative to the rotating computing device 104, but the rotor portion rotates within the stator portion 116 of the slip ring connector 100. An example rotating computing device 104 can be a camera device, such as a security camera, mounted to a fixed base and capable of movement. Further examples include rotating radar and / or lidar sensors, including, for example, radar and lidar transceivers mounted on a car or drone. Radar, lidar, and similar technologies can transmit electromagnetic waves and receive reflected electromagnetic waves to measure the position and / or velocity of an object.
[0047] Now see Figure 2 , an example rotating electrical connector 200 is provided that electrically connects a stationary computing device 202 and a rotating computing device 204. Figure 2 As depicted in FIG, the rotating electrical connector 200 includes a connector housing 230 that encloses a rotating antenna 222 that is electrically connected to the rotating wireless transceiver board 218 and is also electrically connected to the rotating computing device 204 via a rotating data transmission line 226. Figure 2 As depicted in FIG, the rotation computing device 204 may include an interface chip 210 and a processor 214. Figure 2 As depicted in FIG, the rotation computing device 204 may include an interface chip 210 and a processor 214. Figure 2 As further depicted in FIG, the connector housing 230 also encloses the fixed antenna 224. Figure 2 , the rotating antenna 222 is pointed toward the fixed antenna 224 and is configured to transmit and receive wireless data 232 to the fixed antenna 224. The fixed antenna 224 is electrically connected to the fixed wireless transceiver board 220 and to the stationary computing device 202 via a fixed data transmission line 228.
[0048] like Figure 2As depicted in FIG, the example rotating electrical connector 200 includes a connector housing 230. The connector housing 230 can be any housing, enclosure, compartment, and / or similar structure configured to enclose the internal components of the rotating electrical connector 200. The connector housing 230 can include plastic, reinforced plastic, aluminum, steel, and / or any other material configured to protect, stabilize, and / or facilitate movement of the internal components of the rotating electrical connector 200. In some embodiments, the connector housing 230 can enclose the rotating wireless transceiver board 218, the rotating antenna 222, the fixed wireless transceiver board 220, the fixed antenna 224, and other internal components. In some embodiments, the connector housing 230 can provide surfaces and / or attachment points for securing the fixed wireless transceiver board 220 and / or the fixed antenna 224 to the connector housing 230. In some embodiments, the connector housing 230 can include rolling bearings (such as ball bearings) to facilitate rotation of the rotating wireless transceiver board 218 and the rotating antenna 222 within the connector housing 230. Furthermore, the connector housing 230 can be configured to attach the internal components of the rotating electrical connector 200 (e.g., the rotating wireless transceiver board 218, the rotating antenna 222, the fixed wireless transceiver board 220, the fixed antenna 224) so that the fixed antenna 224 and the rotating antenna 222 can transmit and receive data to and from each other. In this instance, the antenna portions of the wireless transceivers (e.g., the rotating antenna 222, the fixed antenna 224) can be pointed toward each other. Additionally, the wireless transceivers can be fixed at a distance (e.g., a separation distance) to facilitate reliable transmission of electronic data without physical contact. For example, in some embodiments, the rotating antenna 222 and the fixed antenna 224 can be positioned such that the distance between the rotating antenna 222 and the fixed antenna 224 is between 0.1 mm and 100 mm, more preferably between 0.5 mm and 50 mm, and most preferably between 1 mm and 30 mm.
[0049] like Figure 2 As further depicted in FIG, the rotating electrical connector 200 includes a fixed wireless transceiver board 220 and a fixed antenna 224 positioned within a connector housing 230. In some embodiments, the fixed wireless transceiver board 220 and the fixed antenna 224 can be manufactured as a single component, referred to herein as a fixed wireless transceiver. The fixed wireless transceiver board 220 can include any insulating material (such as fiberglass or plastic) and provides a conductive path between electrical components. For example, Figure 2The fixed wireless transceiver board 220 depicted in FIG can provide an electrical path between the fixed data transmission line 228 and the fixed antenna 224. In addition, the fixed wireless transceiver board 220 can provide for the attachment and / or placement of electrical components, such as the attachment and / or placement of the fixed antenna 224 on a surface of the fixed wireless transceiver board 220. In some embodiments, the fixed wireless transceiver board 220 can facilitate transmission and reception on an antenna array. In some embodiments, the fixed wireless transceiver board 220 can be attached to a stator portion of the connector housing 230 (e.g., stator portion 316, as in conjunction with FIG). Figure 3 ), such that the fixed wireless transceiver board 220 and the fixed antenna 224 maintain a static orientation relative to the connector housing 230.
[0050] like Figure 2 As further depicted in FIG, the fixed wireless transceiver board 220 can be coupled to a fixed antenna 224. The fixed antenna 224 can be any component or device configured to transmit and receive wireless signals. The fixed antenna 224 can include one or more antennas and accompanying hardware, software, and / or firmware configured to facilitate the transmission and reception of electronic data, such as electronic data exchanged between the stationary computing device 202 and the rotating computing device 204. In some embodiments, the hardware, software, and / or firmware supporting the transmission and reception of electronic data can be included on the fixed wireless transceiver board 220.
[0051] The fixed wireless transceiver can implement several features and strategies to enable the transmission of electronic data (e.g., wireless data 232) at high data rates. For example, in some embodiments, the fixed wireless transceiver can support full-duplex electronic data transmission, thereby enabling simultaneous transmission and reception of wireless data 232. Furthermore, the fixed wireless transceiver can support various modulation schemes for encoding wireless data 232, such as an amplitude shift keying (ASK) modulation scheme, in which the amplitude of a carrier wave is varied to represent electronic data. Furthermore, wireless data 232 can be encoded using other modulation schemes, such as a frequency shift keying (FSK) modulation scheme and a phase shift keying (PSK) modulation scheme. The fixed wireless transceiver can also support encoding wireless data 232 using a non-return-to-zero (NRZ) method, thereby further enabling the transmission of wireless data 232 at higher data rates. In some embodiments, the fixed wireless transceiver can transmit wireless data 232 using a differential signaling method, such as serial low voltage signaling (SLVS), thereby enabling the transmission and reception of wireless data 232 over two conductors. Furthermore, in some embodiments, the fixed wireless transceiver may include multiple antennas formed in an array, thereby enabling the transmission of wireless data 232 using techniques such as beamforming.
[0052] Such technology can enable a fixed wireless transceiver to support high frequencies and fast data rates. For example, in some embodiments, the fixed wireless transceiver can support the transmission and reception of wireless data 232 in the millimeter frequency band. The millimeter frequency band can include a wavelength spectrum between 10 millimeters and 1 millimeter. Thus, in some embodiments, the fixed wireless transceiver can transmit and receive wireless data 232 at frequencies between 30 gigahertz and 300 gigahertz; more preferably, between 40 and 75 gigahertz; and most preferably, between 58 and 62 gigahertz. Transmitting wireless data 232 in the millimeter frequency band can enable the fixed wireless transceiver to transmit and receive data at data rates between 100 megabits per second and 10 gigabits per second.
[0053] Additionally, the fixed wireless transceiver may be configured to utilize electromagnetic waves having circular polarization to transmit and receive wireless data 232. Transmitting and receiving wireless data 232 using circular polarization may enable stable data transmission between the fixed wireless transceiver and the rotating wireless transceiver, even when the rotating wireless transceiver rotates about an axis relative to the fixed wireless transceiver.
[0054] In some embodiments, the fixed wireless transceiver may include a device similar to ST Manufactured ST60A2 transceiver.
[0055] like Figure 2 As further depicted in FIG, the rotating electrical connector 200 includes a rotating wireless transceiver board 218 and a rotating antenna 222 positioned within a connector housing 230, wherein the rotating antenna 222 is directed toward a fixed antenna 224. In some embodiments, the rotating wireless transceiver board 218 and the rotating antenna 222 can be manufactured as a single component, referred to herein as a rotating wireless transceiver. The rotating wireless transceiver board 218 can include any insulating material (such as fiberglass or plastic) that contains conductive pathways between electronic components. For example, Figure 2 The rotating wireless transceiver board 218 depicted in FIG2 can provide an electrical path between the rotating data transmission line 226 and the rotating antenna 222. In addition, the rotating wireless transceiver board 218 can provide for the attachment and / or placement of electrical components, such as the attachment and / or placement of the rotating antenna 222 on the surface of the rotating wireless transceiver board 218. In some embodiments, the rotating wireless transceiver board 218 can facilitate transmission and reception on the antenna array.
[0056] like Figure 2As further depicted in , the rotating wireless transceiver board 218 can be coupled to a rotating antenna 222. The rotating antenna 222 can be any component or device configured to transmit and receive wireless signals. The rotating antenna 222 can include one or more antennas and accompanying hardware, software, and / or firmware configured to facilitate the transmission and reception of electronic data, such as electronic data exchanged between the stationary computing device 202 and the rotating computing device 204. In some embodiments, the hardware, software, and / or firmware supporting the transmission and reception of electronic data can be included on the rotating wireless transceiver board 218. In some embodiments, the rotating wireless transceiver board 218 can be attached to the rotor portion of the connector housing 230 (e.g., with respect to the Figure 3 The rotor portion 338 , further described, causes the rotating wireless transceiver board 218 and the rotating antenna 222 to rotate within the connector housing 230 . In such an embodiment, the rotating wireless transceiver board 218 and the rotating antenna 222 also rotate relative to the fixed antenna 224 .
[0057] The rotating wireless transceiver can implement several features and strategies to enable the transmission of electronic data (e.g., wireless data 232) at high data rates. For example, in some embodiments, the rotating wireless transceiver can support full-duplex electronic data transmission, thereby enabling simultaneous transmission and reception of wireless data 232. Furthermore, the rotating wireless transceiver can support various modulation schemes for encoding wireless data 232, such as an amplitude shift keying (ASK) modulation scheme, in which the amplitude of a carrier wave is varied to represent electronic data. Furthermore, wireless data 232 can be encoded using other modulation schemes, such as a frequency shift keying (FSK) modulation scheme and a phase shift keying (PSK) modulation scheme. The rotating wireless transceiver can also support encoding wireless data 232 using a non-return-to-zero (NRZ) method, thereby further enabling the transmission of wireless data 232 at higher data rates. In some embodiments, the rotating wireless transceiver can transmit wireless data 232 using a differential signaling method, such as serial low voltage signaling (SLVS), thereby enabling the transmission and reception of wireless data 232 via two conductors. Furthermore, in some embodiments, the rotating wireless transceiver may include multiple antennas formed in an array, thereby enabling the transmission of wireless data 232 using techniques such as beamforming.
[0058] Such technology can enable the rotating wireless transceiver to support high frequencies and fast data rates. For example, in some embodiments, the rotating wireless transceiver can support the transmission and reception of wireless data 232 in the millimeter frequency band. The millimeter frequency band can include a wavelength spectrum between 10 millimeters and 1 millimeter. Thus, in some embodiments, the rotating wireless transceiver can transmit and receive wireless data 232 at frequencies between 30 gigahertz and 300 gigahertz; more preferably, between 40 and 75 gigahertz; and most preferably, between 58 and 62 gigahertz. Transmitting electronic data in the millimeter frequency band can enable the rotating wireless transceiver to transmit and receive data at data rates between 100 megabits per second and 10 gigabits per second.
[0059] Additionally, the rotating wireless transceiver may be configured to utilize electromagnetic waves having circular polarization to transmit and receive wireless data 232. Using circular polarization to transmit and receive wireless data 232 enables stable data transmission between the fixed wireless transceiver and the rotating wireless transceiver, even when the rotating wireless transceiver rotates about its axis relative to the fixed wireless transceiver.
[0060] In some embodiments, the rotating wireless transceiver may include a device similar to ST Manufactured ST60A2 transceiver.
[0061] like Figure 2 As further depicted in the example rotating electrical connector 200, the example rotating electrical connector 200 can be electrically connected to the stationary computing device 202 using a fixed data transmission line 228 and electrically connected to the rotating computing device 204 using a rotating data transmission line 226. The data transmission lines (e.g., fixed data transmission line 228, rotating data transmission line 226) can be any wire, cord, channel, waveguide, or other line configured to transmit electronic data, such as a conductive cable and / or a fiber optic cable. The data transmission lines communicatively connect the associated devices to the rotating electrical connector 200. As further described herein, the fixed data transmission line 228 can be connected to the fixed portion of the rotating electrical connector 200 and to the fixed wireless transceiver board 220. The rotating data transmission line 226 can be connected to the rotating portion of the rotating electrical connector 200 and to the rotating wireless transceiver board 218.

In addition, the interface chips 210, 212 may convert electronic data to be transmitted via the rotating electrical connector 200 into a protocol recognizable by the onboard wireless transceiver. For example, in some embodiments, the onboard wireless transceiver may utilize 8-bit / 10-bit encoding to transmit data from one wireless transceiver to another wireless transceiver.

Alternatively or additionally, in some embodiments, the processors 214, 216 may be configured to execute hard-coded functionality. As such, whether configured through hardware, software methods, or a combination of both, the processors 214, 216 represent entities (e.g., physically embodied in circuitry) that are capable of performing operations in accordance with the operation of a particular device. In conjunction with a controller (e.g., reference Figure 6 Controller 602 shown), the specific embodiment of the example processor will be combined with Figure 7 Further description is given.
[0064] Now see Figure 3 , provides a cross-section of an example rotary electrical connector 300. Figure 3 As depicted in FIG, the example rotating electrical connector 300 includes a rotor portion 338 (e.g., a second connector portion) attached to a rotating transceiver base 334 that is configured to attach to a rotating wireless transceiver board 318 including a rotating antenna 322 (e.g., a rotating wireless transceiver). Figure 3 As depicted in FIG, the rotating wireless transceiver board 318 and associated rotating antenna 322 are configured to rotate within the connector housing 330. Additionally, the rotating data transmission line 326 is electrically connected to the rotor portion 338 of the rotating electrical connector 300 and subsequently electrically connected to the rotating wireless transceiver, thereby providing communication with a rotating computing device (e.g., as in conjunction with a Figure 1 and Figure 2 The electrical connection of the rotation calculation device 204).
[0065] like Figure 3 As further depicted in FIG, the rotating antenna 322 is directed toward the fixed antenna 324 separated by a separation distance 342 so that reliable transmission of electronic data can be achieved without wearing out the mechanical slip ring connection. Figure 3 As depicted in FIG, the fixed antenna 324 and the associated fixed wireless transceiver board 320 (e.g., a fixed wireless transceiver) are attached to the fixed transceiver base 336. Subsequently, the fixed transceiver base 336 is attached to the stator portion 316 (e.g., the first connector portion) of the connector housing 330. Thus, the fixed antenna 324 is fixed relative to the connector housing 330, while the rotating antenna 322 rotates relative to the connector housing 330 and the fixed antenna 324. Figure 3 As further depicted in FIG, the fixed wireless transceiver is electrically connected to a fixed data transmission line 328, thereby providing communication with a stationary computing device (e.g., Figure 1 and Figure 2 The electrical connections of the stationary computing device 202 are described.
[0066] Now see Figure 4 , provides another perspective view of an example rotary electrical connector 400. Figure 4 , the example rotating electrical connector 400 includes a rotating antenna 422 and a rotating wireless transceiver board 418 (e.g., a rotating wireless transceiver) attached to a rotating transceiver base 434 of a rotor portion 438 (e.g., a second connector portion) of the rotating electrical connector 400. Furthermore, the rotating antenna 422 is electrically connected to a rotating computing device (e.g., rotating computing devices 104, 204) via a plurality of rotating data transmission lines 426.
[0067] like Figure 4 As further depicted in FIG, the rotating antenna 422 is directed toward the fixed antenna 424 and is separated by a separation distance 442. Figure 4 As depicted in FIG, the fixed antenna 424 and the associated fixed wireless transceiver board 420 (e.g., a fixed wireless transceiver) are attached to the fixed transceiver base 436. Subsequently, the fixed transceiver base 436 is attached to the stator portion 416 (e.g., the first connector portion) of the connector housing 430. Thus, the fixed antenna 424 is fixed relative to the connector housing 430, while the rotating antenna 422 rotates relative to the connector housing 430 and the fixed antenna 424. Figure 4 As further depicted in , the fixed wireless transceiver is electrically connected to the fixed data transmission line 428, thereby providing an electrical connection to the stationary computing device (eg, the stationary computing device 102, 202).
[0068] Now see Figure 5, an example rotary electrical connector 500 is provided, which includes the slip ring connector 100 and a non-contact rotary electrical connector 534 (eg, rotary electrical connectors 200, 300, 400). Figure 5 As depicted in FIG, a rotating electrical connector 500 electrically connects a stationary computing device 502 to a rotating computing device 504 via internal components of the rotating electrical connector 500. The physical electrical connection (e.g., a mechanical slip ring connection) between the stationary computing device 502 and the rotating computing device 504 is provided by the slip ring connector 100. Figure 5 As depicted in FIG, a stationary computing device 502 is electrically connected to a brush block 536 attached to a stator portion 516 of a slip ring connector 100 via a fixed wired connection 508. As described herein, the brush block 536 includes a plurality of conductive pins 510, each corresponding to a wire or line of the fixed wired connection 508. An example rotating computing device 504 is connected to the rotor portion 514 of the slip ring connector 100, which includes a plurality of conductive rings 512. As described herein, each conductive ring corresponds to a wire or line of the rotating wired connection. The conductive pins 510 are pressed against the conductive rings 512, thereby establishing a physical electrical connection or mechanical slip ring connection between the stationary computing device 502 and the rotating computing device 504.
[0069] The mechanical slip ring connection established by the slip ring connector 100 is particularly suitable for power transmission and electronic data at lower data rates (e.g., data transmitted at less than 100 megabits per second). Compared to wireless transmission of power, a mechanical slip ring connection can provide reliable and efficient power transmission. In addition, when the mechanical slip ring connection begins to wear, data transmitted at a lower data rate is less likely to be corrupted or fail to transmit. Electronic data suitable for transmission at a lower data rate can include control and command data, such as a data message requesting an update of a camera position or configuring a camera output.
[0070] like Figure 5 As further depicted in FIG, a high-speed contactless data connection between a stationary computing device 502 and a rotating computing device 504 is provided by a rotating electrical connector 500. Figure 5 As depicted in FIG, the stationary computing device 502 also includes a set of fixed data transmission lines 528. The fixed data transmission lines 528 are electrically connected to the fixed wireless transceiver board 520 and the fixed antenna 524 (referred to herein as the fixed wireless transceiver) of the contactless rotating electrical connector 534. The stationary computing device 502 can transmit and receive electronic data via the fixed data transmission lines 528. The fixed antenna 524 and the fixed wireless transceiver board 520 can be attached to the stator portion 516 of the connector housing 530 so that the fixed wireless transceiver remains fixed relative to the connector housing 530. The fixed wireless transceiver can be configured to transmit wireless data 532 to and receive wireless data 532 from the rotating wireless transceiver.
[0071] In addition, if Figure 5 , the rotating computing device 504 can be electrically connected to the rotating antenna 522 and the rotating wireless transceiver board 518 (referred to herein as the rotating wireless transceiver) via a rotating data transmission line 526. In some embodiments, the rotating wireless transceiver can be attached or otherwise connected to the rotor portion 514 of the slip ring connector 100 so that the rotating wireless transceiver can rotate within the connector housing 530. In some embodiments, the contactless rotating electrical connector 534 can include a separate shaft so that the rotating wireless transceiver can rotate relative to the connector housing 530.
[0072] The high-speed, contactless data connection created by the contactless rotating electrical connector 534 is particularly well-suited for data transmission requiring high data rates, such as electronic data transmitted at frequencies exceeding 30 GHz and requiring data rates exceeding 100 megabits per second. The high-speed, contactless connection can provide a reliable data connection even after the mechanical slip ring connection begins to wear or deform. Electronic data requiring transmission at higher data rates can include high-capacity data, such as video streams from security cameras.

In some embodiments, the controller 602 may issue commands to control and configure the operation of the rotation sensing device 604, such as controlling the position of the rotation sensing device 604. In some embodiments, the controller 602 may also include a power supply for supplying power to the rotation sensing device. In such embodiments, the rotational electrical connector 606 may also include a slip ring connector (e.g., slip ring connector 100) for transmitting power to the rotational sensing device 604 through the rotational electrical connector 606. Figure 7 The example controller 602 is further described.
[0075] like Figure 6 As depicted in , the example system 600 includes a rotational sensing device 604. The rotational sensing device 604 can be any sensor or device, including hardware, software, firmware, and / or a combination thereof, configured to collect data related to the physical environment surrounding the rotational sensing device 604. Additionally, the rotational sensing device 604 can be configured to rotate relative to the controller 602. Non-limiting examples of the rotational sensing device 604 can include radar and / or lidar sensors and associated circuitry, cameras and / or other imaging devices, and the like. The rotational sensing device 604 can be configured to receive commands and configuration electronic data from the controller 602. For example, the rotational sensing device 604 can receive configuration parameters related to exposure time, ISO sensitivity, white balance, shutter speed, gain, frame rate, dynamic range, bit depth, update rate, frame rate, and other parameters related to the received electronic data. In addition, the rotational sensing device 604 can receive configuration data related to the position of the rotational sensing device 604. For example, the controller 602 can direct the rotational sensing device 604 to a specific yaw, pitch, and roll based on the electronic data received from the rotational sensing device 604. The rotational sensing device 604 can also be configured to provide electronic data to the controller 602. For example, the rotational sensing device 604 can transmit image data and / or other sensory data to the controller 602. Such data may need to be transmitted at a high frequency (e.g., greater than 30 gigahertz) and / or a high data rate (e.g., greater than 100 megabits per second). The rotating electrical connector 606 can utilize the rotating transceiver 622 and the fixed wireless transceiver 624 to reliably transmit such high-speed data.

[0082] As a specific example embodiment, processor 702 is configured to perform various operations associated with initializing a rotational sensing device (e.g., rotational sensing device 604) and interacting with the rotational sensing device. In some embodiments, processor 702 includes hardware, software, firmware, and / or a combination thereof for transmitting low data rate messages to the rotational sensing device via a rotating electrical connector (e.g., rotating electrical connector 606, rotating electrical connector 500).

[0087] Now see Figure 8 , provides a flow chart illustrating an example method 800 for transmitting electronic data in a rotating electrical connector (e.g., rotating electrical connector 500). At block 802, the rotating electrical connector can receive a signal from a first wireless transceiver (e.g., Figures 2 to 6 ) transmits the first electronic data to a second wireless transceiver (e.g., Figures 2 to 6) receives the first electronic data at a rotating wireless transceiver described in . As described herein, the rotating electrical connector can include a high-speed contactless connection between two computing devices (e.g., stationary computing device 502, rotating computing device 504). The high-speed contactless connection can utilize a first wireless transceiver and a second wireless transceiver separated by a certain distance. The separation of the wireless transceivers allows the rotating electrical connector to rotate, and the wireless transceivers can rotate relative to each other without causing any wear or strain on the communication components. The proximity of the wireless transceivers enables the transmission of electronic data (e.g., first electronic data, second electronic data) to occur at a high frequency and / or high data rate. For example, the frequency is between 58 and 62 gigahertz, and the data rate is between 100 megabits per second and 10 gigabits per second. The high-speed contactless connection may be more preferred for transmitting data from the first computing device to the second computing device (which may need to be transmitted at a high frequency (e.g., greater than 30 gigahertz) and / or a high data rate (greater than 100 megabits per second)). The data transmitted over the high-speed contactless connection of the rotating electrical connector may include high priority command and control data and / or include a large payload. The electronic data transmitted from the first computing device to the second computing device may be transmitted by the first wireless transceiver and received by the second wireless transceiver.
[0088] At block 804, the rotating electrical connector may transmit second electronic data from the second wireless transceiver and receive the second electronic data at the first wireless transceiver. The high-speed contactless connection may also be utilized to transmit electronic data from the second computing device to the first computing device. The data transmitted over the high-speed contactless connection of the rotating electrical connector may include high-priority status data, high-priority sensor data, image data, streaming video, and / or other sensor data. The electronic data transmitted from the second computing device to the first computing device may be transmitted by the second wireless transceiver and received by the first wireless transceiver.
[0089] At block 806, the rotating electrical connector may receive power from a power source. In some embodiments, the first computing device (e.g., stationary computing device 102, 202, 502, controller 602) may include a power source. In some embodiments, the power source of the first computing device may be utilized to power a second computing device (e.g., rotating computing device 104, 204, 504, rotation sensing device 604). In such embodiments, power may be transferred from the power source of the first computing device to the rotating electrical connector, and then to the second computing device.
[0090] At block 808, the rotating electrical connector can transmit power to a second computing device (e.g., rotating computing device 104, 204, 504, rotating sensing device 604) through electrical contact between the conductive pins (e.g., conductive pins 110, 510) and the conductive rings (conductive rings 112, 512). As described herein, a mechanical slip ring connection can provide physical electrical contact between the conductive pins and the conductive rings. In some embodiments, a mechanical slip ring connection can be more reliable and more efficient in transmitting power than wireless transmission. In addition, power transmission via a mechanical slip ring connection may not be severely affected by wear on the physical electrical contacts of the slip ring connection. In this way, the rotating electrical connector can transmit power via the mechanical slip ring connection while transmitting high-frequency and / or high-data-rate electronic data via a high-speed contactless connection. In some embodiments, the rotating electrical connector can also utilize a mechanical slip ring connection to transmit electronic data transmitted at lower frequencies (e.g., less than 30 gigahertz) and lower data rates (e.g., less than 100 megabits per second).
