  • Patent number: 10790936
    Abstract: Disclosed is a mechanism to help a user equipment device (UE) transmit multiple distinct bit streams concurrently to a base station with reduced risk of interference. The UE will orthogonally encode the multiple distinct bit streams using orthogonal binary codes to produce orthogonally encoded bit streams, and the UE will add the orthogonally coded bit streams together to produce a resulting bit stream and will transmit that resulting bit stream on an antenna path to the base station. Upon receipt of the transmitted bit stream, the base station could then apply the same orthogonal binary codes to the bit stream in order to extract the underlying multiple distinct bit streams.

In some examples of the disclosed technology, groups of cameras for high dynamic range (HDR), polarization diversity, and optional other diversity modes are arranged to concurrently image a common scene. For example, in a vehicle checkpoint application, HDR provides discernment of dark objects inside a vehicle, while polarization diversity aids in rejecting glare. Spectral diversity, infrared imaging, and active illumination can be applied for better imaging through a windshield. Preprocessed single-camera images are registered and fused. Faces or other features of interest can be detected in the fused image and identified in a library. Impairments can include weather, insufficient or interfering lighting, shadows, reflections, window glass, occlusions, or moving objects.

  • Patent number: 10742222
    Abstract: Techniques are described for peak-adaptive sampling demodulation for radiofrequency transceivers. For example, a tag input signal is received via an antenna, from which a clock input signal can be extracted. Multiple clock output signals can be generated responsive to the extracted clock input signal, such that each has a different respective phase. A multiphase selector can identify the one of the clock output signals that has the respective phase that is closest to the phase of the tag input signal and is best suited for sampling the peak of the tag input signal, accordingly. A single-path detector can generate a data output signal by using the identified clock output signal to sample the tag input signal, and the detector can filter and amplify the data output signal using small-signal devices.

  • Patent number: 10735753
    Abstract: Data compression using a memristive crossbar is enabled. Conductances of memristors may be set such that the memristors of the crossbar act as coefficients of a wavelet transformation coefficient matrix with respect to voltage signals applied to input rows of the crossbar. The memristors may act as coefficients of the transpose of the wavelet transformation coefficient matrix when voltage signals are applied to input columns of the crossbar. Hence, the memristive crossbar may be used to implement a two dimensional (2D) discrete wavelet transform (DWT) on two dimensional data (e.g., image data) encoded in the voltage signals. The resulting currents in the columns of the memristive crossbar may be integrated and converted to voltage signals that are fed back into columns of the memristive crossbar such that the rows of the memristive crossbar output electronic signals that correspond to the image data compressed in accordance with Haar 2D-DWT image compression.
