Abstract: The invention concerns a sensing device (1) configured to selectively operate in: a manufacturing mode, an unprovisioned mode, a provisioned mode and an end-of-life mode. In the manufacturing mode, the electronic circuit (14) permanently stores a unique code (149) in a storage medium (12), while in the unprovisioned mode, the electronic circuit (14) waits for a provisioning code (31) for generating a private and a public key (143). In the provisioned mode, the electronic circuit (14) signs a timestamp (146) provided by a time-keeping unit (13) and data (110) provided by a sensing unit. The collected data (110), the timestamp (146), the digital signature (144) and the public key (143) is then transmitted. In the end-of-life mode, the electronic circuit (14) permanently erases the private key.

Abstract: A communication system may include an access point (AP), a user equipment (UE), and a communication path between the AP and the UE having a series of reconfigurable intelligent surfaces (RIS's). Each RIS may have a first beam pointing to a previous node and a second beam pointing to a next node in the communication path. Beams of routing RIS's and a beam from an end user RIS towards a last routing RIS may be set during calibration. The UE may perform beam discovery with the end user RIS. The UE and the AP may convey wireless data via reflections off each of the RIS's in the communication path. The beam of the end user RIS may be updated to track the UE device while the other the beams remain fixed. The beams may be calibrated using retroreflection and beam variation for each pair of RIS's up the communication path.

Abstract: A system may include an access point (AP), a user equipment (UE) device, and a reconfigurable intelligent surface (RIS). The RIS may have antenna elements and phase shifters programmed using phase settings to form signal beams. The AP may calculate a first portion of the phase settings and may transmit the first portion to the RIS. The RIS may include a first processor that generates a second portion of the phase settings. The RIS may include a second processor coupled to the first processor over a bus. The second processor may generate the phase settings based on the second portion. The second processor may distribute the phase settings to the phase shifters. By distributing calculation of the phase settings between the AP and the RIS, power consumption of the system may be minimized while also minimizing the time required to re-configure the beams of the RIS.

Abstract: A method and apparatus according to the present invention addresses and/or prevents lost protocol synchronization in HARQ systems caused by ACK/NACK errors. One embodiment detects lost synchronization errors for NDI-based retransmission protocols and restores synchronization by sending an explicit RESET message. In response to the RESET message, the transmitter aborts the transmission of a current PDU and transmits a new PDU and corresponding NDI. Another embodiment prevents protocol synchronization errors by sending scheduling grants on a packet by packet basis. The receiver sends a subsequent explicit scheduling grant to the transmitter based on an error evaluation of a received PDU. The transmitter will not send the next PDU unless it receives the subsequent explicit scheduling grant.

The first axis of rotation, the second axis of rotation and a central beam of the X-ray generator intersect at one point in all positions of the support arm and of the mount.

Abstract: A user equipment (UE) device may communicate with a wireless access point (AP) via reflection off a reconfigurable intelligent surface (RIS). The RIS may begin to sweep antenna elements over one or more sets of signal beams beginning at an initial time while reflecting signals transmitted by the AP. The UE may record times at which the UE receives reference signals reflected by the RIS. The UE may select an optimal signal beam of the RIS based on the time periods between the initial time and the times at which the reference signals were received. The UE may inform the AP of the optimal signal beam and the RIS may use the optimal signal beam to reflect wireless data between the AP and the UE. Multiple signal beam sweeps may eliminate uncertainty or ambiguity in signal beam selection associated with timing drift or offsets between the RIS and the UE.

Abstract: A wireless access point (AP) may communicate with a user equipment (UE) device via reflection off a reflective device having an array of fixed or adjustable reflectors in different orientations. The AP may illuminate different portions of an area by pointing a signal beam to different reflectors and/or by controlling the reflective device to electrically rotate the reflectors. The AP may calibrate the position of the reflective device and may establish wireless communications with the UE device by performing a sweep of signal beams over the reflectors and/or by controlling the reflective device to sweep over different reflector orientations. The AP may track movement of the UE device over time. The AP may sweep the AP beam over a subset of the reflectors around an active reflector to maintain communications with the UE device even as the UE device moves over time.

Abstract: A controller may map user equipment (UE) devices in a wireless system to access points (AP) and reflective intelligent surfaces (RIS). The controller may generate a corresponding communications schedule based on the locations of the UE device(s), AP(s), and RIS(s) and based on current traffic demands. The controller may control the RIS(s), AP(s), and UE devices to implement the schedule. The schedule may divide the time, frequency, and/or spatial resources of the RIS(s) to meet the traffic demands of the UE devices using a space division multiple access scheme, a time-division multiple access scheme, a frequency-division multiple access scheme, and/or a distributed multiple-input and multiple output scheme. The schedule may be updated over time as needed. The RIS(s) may allow for a reduction in the number of AP(s) required to meet the dynamic demands of the UE devices, thereby minimizing deployment and operating costs.

Abstract: A user equipment (UE) device may communicate with a wireless access point (AP) using wireless signals transmitted using a data radio access technology (RAT) via reflection off a reconfigurable intelligent surface (RIS) at frequencies greater than about 100 GHz. A control RAT may be used to convey control signals between the AP, UE device, and RIS. The control signals and the control RAT and the data transfer RAT may split procedures used to perform discovery, to establish an initial configuration of the UE device, AP, and/or RIS, and to update the configuration of the UE device, the AP, and/or the RIS while tracking the UE device over time. The control RAT may allow for control operations without requiring line-of-sight and may allow the RIS to minimize its power consumption and cost.

Abstract: A user equipment (UE) device may communicate with an access point (AP) at greater than 100 GHz via a reconfigurable intelligent surface (RIS). The AP may perform a control RAT discovery with the RIS and then a data transfer RAT discovery, during which the AP uses the control RAT to control the RIS to sweep over different RIS beams. The AP may transmit radar waveforms while concurrently sweeping over different AP beams. The AP may gather performance metric values from the radar waveforms after reflection off the RIS during the sweep. The AP may identify an optimal RIS beam that produced the best performance metric values. The AP may use the optimal RIS beam to identify the orientation of the RIS, which the AP may use to select AP and/or RIS beams for conveying wireless data between the AP and the UE via the RIS.

Abstract: A user equipment (UE) device may communicate with an access point (AP) at greater than 100 GHz via a reconfigurable intelligent surface. The UE may select tracking beams based on sensor data. The UE may instruct the RIS to sweep over the tracking beams while the UE gathers performance metric data. The UE may identify a serving beam based on the performance metric data. The UE may control the RIS to form the serving beam to reflect wireless data between the AP and the UE. Using the UE to intelligently select tracking beams based on sensor data may greatly reduce the amount of time required to track the UE device as it moves relative to sweeping over all formable signal beams, thereby reducing latency and minimizing disruptions in wireless data transfer between the UE device and the AP.
