  • Patent number: 11540384
    Abstract: An apparatus comprises a transceiver (Tx/Rx) printed circuit board (PCB) with a top surface and a bottom surface and a power supply PCB. The Tx/Rx PCB includes two transmitter devices, each comprising a number N of channels. A first transmitter device is arranged on the bottom surface and a second transmitter device is arranged on the top surface over the first transmitter device. One or more pins of the second transmitter device are shorted with one or more pins of the first transmitter device with the same function. An analog front end (AFE) device comprising N input channels is arranged on the top surface of the Tx/Rx PCB, and a digital signal processor is coupled to the AFE device. The power supply PCB comprises a power supply module configured to provide a plurality of supply voltages to the Tx/Rx PCB and the power supply PCB.

  • Patent number: 10965240
    Abstract: A hardware-based detection system includes, among other things, a signal-generating circuit for generating a signal which is functionally related to current in a motor winding, a reference current, and a duration of time. The system may also include a comparator circuit for comparing the generated signal to a reference signal, and for thereby detecting an over-temperature condition in the motor winding. If desired, a compensating circuit may be used to generate a variable reference signal as a function of ambient temperature. A method of operating a detection system is also disclosed. If desired, the detection system may be completely implemented in hardware using an uncomplicated analog circuit architecture.
