  • Patent number: 11282372
    Abstract: Disclosed is a method for detecting tampering of a target detection system, comprising a control unit is in signal communication with a set of present tamper detection sensors, which are associated with a detection member. The method includes setting an overall sensor coordination logic for determining a tamper state of the system based on tamper detection data from a predetermined set of sensors, wherein the set of present sensors is a subset. Then, the control unit controls the operating state of each sensor of the set of present sensors and defines a reduced sensor coordination logic, excluding those sensors of the predetermined set that are missing and/or non-working from the overall logic. Thus, the present and working sensors cyclically acquire tamper detection data, and the control unit determines the tamper state of the system by processing the data acquired based on the reduced logic.

  • Patent number: 11205016
    Abstract: An optical electromagnetic radiation (EM) emitter and receiver are located upon a printed circuit board (PCB) layer and are optically connected to an optical security pathway that is between a pair of signal traces. A predetermined reference flux is determined, the reference flux being the expected EM transmitted by the optical security pathway and received by the receiver. When the PCB is subject to an unauthorized access thereof (e.g., drilled, sawed, cut, etc.), the optical EM transferred by optical security pathway is altered. An optical monitoring device that monitors the flux of the optical EM received by the receiver detects a change in flux, in relation to the reference flux, and passes a tamper signal to one or more computer system devices to respond to the unauthorized access. For example, one or more cryptographic adapter card or computer system functions or secured crypto components may be disabled.

  • Patent number: 11162788
    Abstract: A high-definition map system receives sensor data from vehicles traveling along routes and combines the data to generate a high definition map for use in driving vehicles, for example, for guiding autonomous vehicles. A pose graph is built from the collected data, each pose representing location and orientation of a vehicle. The pose graph is optimized to minimize constraints between poses. Points associated with surface are assigned a confidence measure determined using a measure of hardness/softness of the surface. A machine-learning-based result filter detects bad alignment results and prevents them from being entered in the subsequent global pose optimization. The alignment framework is parallelizable for execution using a parallel/distributed architecture. Alignment hot spots are detected for further verification and improvement. The system supports incremental updates, thereby allowing refinements of subgraphs for incrementally improving the high-definition map for keeping it up to date.

  • Patent number: 11105954
    Abstract: A power beaming system includes a power beam transmitter arranged to transmit the power beam, and a power beam receiver arranged to receive the power beam from the power beam transmitter. A power beam transmission source is arranged to generate a laser light beam for transmission by the power beam transmitter from a first location toward a remote second location. A beam-shaping element shapes the laser light beam, at least one diffusion element uniformly distributes light of the shaped laser light beam, and a projection element illuminates a power beam receiving element of predetermined shape with the shaped laser light beam. At the power beam receiver, a diffusion surface diffuses a portion the power beam specularly reflected from the power beam receiver.

  • Patent number: 11108393
    Abstract: An optical keyswitch includes a keycap, a supporting mechanism having a protrusion disposed under the keycap to support the keycap to move downward or upward, and a switch module including a circuit board, an emitter, and a receiver. The emitter and the receiver are electrically connected to the circuit board. The emitter emits an optical signal to the receiver. When the keycap is not pressed, the receiver receives the optical signal of a first intensity. When the keycap is pressed, the protrusion moves along with the keycap, and the protrusion changes the optical signal received by the receiver to have a second intensity different from the first intensity, so the switch module is triggered to generate a triggering signal.

  • Patent number: 11099295
    Abstract: Apparatus and associated methods relate to a photoelectric sensor system having a transmitter and a receiver, and at least one aperture module configured to modify a nominal field of view (FOV) of the transmitter and/or receiver, such that an overlap between the transmitter and receiver FOVs is controlled. In an illustrative example, the aperture module may be a plate having respective receiver and transmitter apertures. The transmitter and/or receiver apertures may be aligned or slightly offset from respective transmitter and receiver optical axes. The transmitter and/or receiver apertures may have a specific size/shape/position that produces a custom predetermined FOV overlap. At least one registration/alignment pin may extend through the aperture plate, a baffle, and a lens module to control orientation. The photoelectric sensor system may advantageously (1) be more resistant to the “white card effect,” (2) increase maximum sensor range, and (3) control the shape/size/overlap of the FOVs.
