Abstract: Methods, systems, and devices for wireless communications supporting techniques for enhanced line-of-sight (LOS) communications with analog multi-path beamforming are described. A first wireless device may receive, from a second wireless device, an indication of a capability of the second wireless device to concurrently transmit first signaling in a first analog beamforming direction using a first transmission configuration indicator (TCI) state corresponding to a LOS mode, and second signaling in a second analog beamforming direction using a second TCI state corresponding to an indirect LOS mode. The first wireless device may then receive, from the second wireless device, a first downlink message in the first analog beamforming direction using the first TCI state concurrently with a second downlink message in the second analog beamforming direction using the second TCI state.

Abstract: A system for safe transmission of an RF electromagnetic power beam to a receiver for conversion into electric power. The receiver has an antenna array for receiving the RF beam and electrical circuitry to receive a corresponding RF electrical current from the antenna array. The circuitry includes a converter for generating DC current from the RF electrical current, and includes at least one component that reflects part of the RF current back towards the antenna array. This converts the reflected portion of the RF electrical current into a retransmitted RF electromagnetic beam having the same frequency as the RF electromagnetic power beam, and is directed back towards the transmitter. The receiver monitors the reflected RF current, and transmits a proportional signal back to a controller. The controller reduces the transmitted power beam if its interference with the retransmitted beam would generate a field intensity above a safe level.

Abstract: A wireless optical power transmission system comprising a transmitter and receiver, the transmitter comprising a laser emitting a beam, a scanning mirror for steering the beam towards said receiver and a control unit receiving signals from a detection unit on the receiver and controlling the beam power and the scanning mirror. The receiver has a photovoltaic cell having a bandgap energy of 0.75-1.2 eV, with a plurality of conductors on a beam receiving surface. A cover layer of material blocking illumination of wavelengths outside that of the laser, is disposed on the photovoltaic cell. The cover layer may have anti-reflective coatings on its top and bottom surfaces. The detection unit thus generates a signal representing the power of the laser beam impinging upon the receiver, independent of illuminations other than that of said laser beam. The control unit thus can maintain the laser power impinging on the receiver.

Abstract: A laser system involving coupled distributed resonators disposed serially, with the lasing gain medium located in the main resonator and the output of that resonator being directed into a free space resonator, such that the main resonator output mirror is effectively the free space resonator. The distributed resonators end mirrors are retroreflectors. Interference occurs between light traveling towards the remote mirror of the free space resonator and light reflected therefrom, generating regions of high reflectivity. The coupling of the free space resonator to the regions of high reflectivity of the free space resonator enables the first resonator to lase efficiently, even though the true reflectivity of the main resonator output mirror outside of those regions is insufficient to enable efficient lasing, if at all. This coupled resonator structure enables lasing to occur with a high field of view and the high gain engendered by the high reflectivity regions.

Abstract: The disclosure discloses various systems, apparatuses, devices, and methods for verification and testing of hardware description language (HDL) and field-programmable gate array (FPGA) designs. A waveform dump generated in a verification environment or in-FPGA environment can be used to prepare a stimulus file that is configured to reduce the time needed to fix an error/issue found in an HDL/FPGA design. In the verification environment, the stimulus file can reduce the simulation time of an HDL design needed to reproduce the error/issue encountered in a full cycle simulation. Similarly, in the in-FPGA environment, the stimulus file can reduce the simulation time needed to reproduce the error/issue encountered in the FPGA hardware test. In both cases, the techniques for configuring stimulus file can accelerate the process of debugging, testing, and verifying a design using simulation.

Abstract: A wireless power transmitter system for directing a high energy beam towards receivers fitted with identifying signs. One type of the identifying signs may have asymmetric shape properties, such that their mirror image cannot be matched to their actual shape, even after the image is rotated, tilted or otherwise geometrically manipulated. The system can thus determine whether a detected image of a sign is a true image received directly from said receiver, or is received after the imaged beam has undergone a reflection between the receiver and the transmission system. In the latter case, the system can prevent high power transmission from being directed to a location other than a real receiver, which could be a safety hazard. Other types of identifying signs may be located in or on the borders of different zones of a transmission space, to identify zones where transmission may be allowed or prohibited.
