Abstract: A local dimming system for a head up display (HUD) according to the present invention comprises a light array, a Fresnel lens array, a lenticular lens system, and a liquid crystal display (LCD). The Fresnel lens array is operatively associated with the light array to provide a collimated backlight output to produce an image on the LCD. The Fresnel lens array focuses light from the light array while reflecting stray light, eliminating light bleed and reducing or eliminating a display-boundary or “postcard effect.” The Fresnel lens array is compact to enable HUD packaging necessary to configure the HUD for use in vehicles, while also removing the need for reflectors which create shadows on the LCD.

Abstract: Examples of amplifier circuitry regulate a transconductance value (Gm) of operational transconductance amplifiers (OTAs) in the amplifier to be approximately the same, which value is based on a supply voltage and a reference voltage applied to a reference OTA and the internal resistance of the reference OTA. The reference OTA generates an output current based on Gm and the reference voltage, which current is compared to current generated by the supply voltage and internal resistance of the reference OTA. A tail current transistor of each of the reference OTA and a main OTA that mirrors the Gm of the reference OTA provide a tail current feedback path by which Gm is regulated. Amplifying circuitry is coupled to the main OTA to receive current signals. Based on the received current signals, amplifying circuitry generates a differential output voltage signal. The gain of the amplifying circuitry is proportional to the supply voltage and remains relatively constant across process temperature variations.

Abstract: A position fix identifying a geographic location of a receiver is received. The position fix was generated using signals received at the receiver from respective high-altitude signal sources (such as satellites). Imagery of a geographic area that includes the geographic location is also received. The imagery is automatically processed to determine whether one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated. In response to determining that one or more of the high-altitude signal sources were occluded from the geographic location when the position fix was generated, the position fix is identified as being potentially erroneous.

Abstract: The invention discloses an UWB NLOS signal recognition method based on the first path of CIR, including constructing a UWB ranging system comprising tags and anchors. The system controls communication between the anchor and tag, processes the raw CIR data obtained from each communication to construct data samples, and labels these samples to build a raw CIR dataset. Peak filtering is then performed on the CIR waveforms in the raw CIR dataset to identify the first path peak points of the data samples. Based on the first path peak points, valid data is determined as new data samples, and one-hot encoding is applied to the data labels. A training dataset is constructed using all new data samples and their corresponding data labels. A machine learning model is then developed and trained using the training dataset, and the trained model is saved for identifying unknown CIR signals.

Abstract: Beam alignment is a critical requirement in 5G-Advanced and 6G due to the high density of user devices anticipated in the coming years. However, prior-art beam alignment procedures are slow and costly in terms of resource usage. Therefore, disclosed herein are methods enabling a user device to determine the direction toward the base station rapidly at very low cost. The base station emits a tailored pulse with an angle-dependent phase, varying from a first phase at a first angle, to a second phase at a second angle, followed by a uniform-phase calibrator pulse. The user device can measure the as-received phase of the tailored pulse relative to the calibrator pulse, and thereby determine the user's direction relative to the base station. The user device can then inform the base station of the received phase, which is proportional to the angle. Both user and base station thereby obtain instant beam alignment.
