  • Patent number: 11901883
    Abstract: Overload detection and protection for power switch circuits. For circuits with faster switching speed, fast fault detection and response to a detected overload condition may be desirable. Detection circuitry may monitor a voltage on the control terminal of one or more power switches. Based on empirical measurements, in an overload condition of a power switch circuit, e.g., a half-bridge circuit, the voltage at the control terminal may increase, and in some examples, increase to a magnitude that is greater than a supply voltage. A comparator may detect a voltage increase that exceeds a voltage magnitude threshold, output an indication to control circuitry for the power switch circuit, and the control circuitry may take action to protect the rest of the circuitry, such as reduce voltage or shut off the power switch circuit.

  • Patent number: 11899094
    Abstract: Systems, methods, and circuitries are disclosed for compressing radar data. In one example, a method includes storing radar data in a memory, the radar data being stored in a data cube having a slow-time dimension, a fast-time dimension, and a channel dimension. The data cube is divided into one or more zones. For each zone a number of data matrices is selected based on a compression factor. Sets of data matrices containing the number of data matrices are formed and, for each set of data matrices, for each data matrix, the data vectors are coded to generate a coded data matrix. A coding for data vectors in a data matrix is the same and a coding for different data matrices is different. The coded data matrices are combined to generate a compressed data matrix for the zone and the compressed data matrices for the one or more zones are stored.
