Abstract: Existing multistatic configurations of Radar systems requires a direct LoS signal and/or time synchronization among the Radar transmitter and the multistatic distributed Radar receivers. The present disclosure provides a phaseless frequency-modulated continuous-wave multistatic Radar (PFMR) imaging that relaxes requirement of the direct LoS signal and only requires a plurality of parameters of a FMCW signal comprising a chirp signal rate, a carrier frequency and, a period of chirp to be known. Further, it also removes condition of the time synchronization among a plurality of FMCW multistatic distributed Radar receivers. However, because of absence of the time synchronization among a plurality of FMCW multistatic distributed Radar receivers, an unknown random phase offset appears after deramping.

Abstract: Innovations in the area of prediction of block vector (“By”) values improve encoding or decoding of blocks using intra block copy (“BC”) prediction. For example, some of the innovations relate to use of a default BV predictor with a non-zero value. Other innovations relate to use of a selected one of multiple BV predictor candidates for a current block. Still other innovations relate to use of a skip mode in which a current intra-BC-predicted block uses a predicted BV value.

Abstract: Single-chip solutions and related methods that result in much higher capacitance densities than is achievable with current on-chip solutions and which reduce consumption of planar area of a mounting structure. Embodiments of the present invention use vertical stacking to affix one or more discrete embeddable capacitors to an IC chip superstructure or base structure, and either sequentially or concurrently form electrical connections between the discrete embeddable capacitors and the IC chip. The inventive processes are compatible with CMOS fabrication temperatures for the IC chip while allowing use of capacitors that are fabricated using other processes that may involve much higher temperatures. The inventive processes allow connection of relatively large capacitances (e.g., ˜0.5 ?F-1 ?F) to an IC chip without increasing the 2-D footprint of the IC chip.

Abstract: A wireless communication network delivers status information for User Equipment (UE) upon request. A network controller exchanges registration signaling with the UE and exchanges authentication signaling for the UE with a Unified Data Management (UDM). The UDM exchanges the authentication signaling with the network controller and responsively transfers a UDM request for the UE status information to the network controller. The network controller determines the UE status information and transfers the UE status information to the UDM in response to the UDM request. The UDM receive the UE status information from the network controller and transfers the UE status information to a Unified Data Repository (UDR). The UDR receives the UE status information from the UDM and receives a status request for the UE from a network element. The UDR responsively transfers the UE status information for the UE to the network element.

Abstract: The present disclosure relates to circuits for connecting components of a hydrogen plant to a power grid to power the components in an efficient manner. In one implementation, power-side alternate current (AC) to direct current (DC) converters may be connected to a source power grid without the need for an isolation transformer by providing separate buses between the power-side AC-DC converters and load-side DC-DC converters instead of a shared DC bus between the converters. Other implementations for connecting components of a hydrogen plant to a power grid may include an adjustable transformer, such as a tappable transformer or an autotransformer, to connect any number of auxiliary loads of the plant to the power grid. The adjustable transformer may provide for various types of auxiliary load devices to connect to the power provided by the transformer at the same time, including both three-phase devices and one-phase devices.

Abstract: Conventional gesture detection approaches demand large memory and computation power to run efficiently, thus limiting their use in power and memory constrained edge devices. Present application/disclosure provides a Spiking Neural Network based system which is a robust low power edge compatible ultrasound-based gesture detection system. The system uses a plurality of speakers and microphones that mimics a Multi Input Multi Output (MIMO) setup thus providing requisite diversity to effectively address fading. The system also makes use of distinctive Channel Impulse Response (CIR) estimated by imposing sparsity prior for robust gesture detection. A multi-layer Convolutional Neural Network (CNN) has been trained on these distinctive CIR images and the trained CNN model is converted into an equivalent Spiking Neural Network (SNN) via an ANN (Artificial Neural Network)-to-SNN conversion mechanism. The SNN is further configured to detect/classify gestures performed by user(s).

Abstract: A wireless communication network deregisters network functions. In the wireless communication, a network data system receives a deregistration command that indicates a wireless User Equipment (UE) and forwards the deregistration command to a Unified Data Management (UDM). The UDM receives the indication and determines a Data Network Name (DNN) for the wireless UE. The UDM identifies a network controller and a session controller for the wireless UE based on the DNN. The UDM transfers deregistration notifications to the network controller and session controller. The UDM receives a deregistration acknowledgement from the network controller. The UDM directs the network data system to remove stored session data for the session controller. The network data system receives the direction from the UDM and responsively removes stored session data for the session controller.
