  • Garment integrated dry electrode for vital signal and electromyography sensing
    Patent number: 11647952
    Abstract: Embodiments of the disclosure provide systems and methods for wearable dry electrodes for collecting biometric information. According to one embodiment, a dry electrode bio-sensor can comprise one or more conductive pads comprising electrodes of the dry electrode bio-sensor and one or more connectivity traces coupled with each of the one or more conductive pads. The connectivity traces can provide electrical connections for one or more of power to the one or more conductive pads or signals comprising biometric information from the one or more conductive pads. A backing can be coupled with and can retain the one or more conductive pads and the one or more connectivity traces. The dry electrode bio-sensor can comprise an electrocardiography (ECG) sensor, a respiration sensor, a PhotoPlethysmoGram (PPG) sensor, a temperature sensor, an electromyography (EMG) sensor, or another biometric sensor.

  • Diaphragm pump system having re-priming capabilities
    Patent number: 9441518
    Abstract: An example system includes a diaphragm pump having a suction port and a discharge port, a urea suction line fluidly coupling a urea supply to the suction port, and a urea discharge line fluidly coupled to the discharge port. A recirculation line fluidly couples the urea discharge line to the urea suction line, and has a flow regulator operationally coupled thereto. A controller is configured to interpret a prime loss condition of the diaphragm pump, and to provide a flow regulator command in response to the prime loss condition.
