  • Patent number: 10847212
    Abstract: A read and write data processing apparatus and method associated with computational memory cells formed as a memory/processing array provides the ability for selected write data in a bit line section to be logically combined (e.g. logically ANDed) with the read result on a read bit line, as if the write data were the read data output of another computational memory cell being read during the read operation. When accumulation logic is implemented in the bit line sections, the implementation and utilization of additional read logic circuitry provides a mechanism for selected write data in a bit line section to be used as the data with which the read result on the read bit line accumulates, before the newly accumulated result is captured and stored in the bit line section's read register.

  • Patent number: 10777262
    Abstract: A read register is provided that captures and stores the read result on a read bit line connected to a set of computational memory cells. The read register may be implemented in the set of computational memory cell to enable the logical XOR, logical AND, and/or logical OR accumulation of read results in the read register. The set of computational memory cells with the read register provides a mechanism for performing complex logical functions across multiple computational memory cells connected to the same read bit line.

  • Patent number: 10637259
    Abstract: A short-circuit current protecting method of a charging control system is cooperating with at least a control unit and a plurality of power outlet electrically connected to an electronic switch. The control unit controls the mode of the electronic switches with turn on or off. The short-circuit current protecting method includes the following steps. Step 1 is detecting at least a current signal value of an AC power. Step 2 is determining whether the current signal value is grater than a predetermine current threshold. Step 3 is enabling a short-circuit current analyzing module if the current signal value is grater than the predetermine current threshold. Step 4 is turning off at least one of the electronic switches if the short-circuit current is determined by the short-circuit current analyzing module.

  • Patent number: 10367371
    Abstract: An intelligent charging system comprises a first switching element, a phase detecting device, a current detecting device and a controller. The first switching element is turned on or off based on a first control signal. The phase detecting device is configured to determine an allowable phase time interval of a phase of a power source. The current detecting device is connected to the first switching element. The current detecting device is configured to detect a first turned on time point when the first switching element is turned on. The controller is connected to the phase detecting device and the current detecting device. The controller is configured to determine whether the first turned on time point is within the allowable phase time interval. If the first turned on time point is not within the allowable phase time interval, the controller resets a first control parameter of the first control signal.
