  • Patent number: 9285411
    Abstract: A system and method for identifying an electrical noise propagation path through an object, such as an automotive vehicle, from a source of periodic electrical noise. An electrical noise sensor is positioned at a selected area on the object which generates an output signal representative of the magnitude of the electrical noise. A trigger generator generates a trigger signal in synchronism with a source of periodic electrical noise and that trigger signal is connected as an input signal to measurement equipment connected to the sensor to initiate electrical noise reading by the sensor. A recorder then records the output from the sensor. The electrical noise sensor is moved to different areas on the object to determine the electrical noise propagation path.

  • Patent number: 9076605
    Abstract: The Present Disclosure provides a touch panel, which consists of a main panel and a light-emitting touch module mounted under the main panel. The light-emitting touch module consists of a first circuit board provided with a plethora of touch sensors and light-emitting devices under the main panel. These touch sensors are used to induce the approaching signals of the operator, and transmit the induction signals to a touch control circuit for controlling the light-emitting status of the corresponding light-emitting device. The light-emitting touch module also consists of a second circuit board, electrically connected with the first circuit board. The touch control circuit is provided on the second circuit board, spatially separated from the first circuit board by a certain distance, so that the electromagnetic interferences of the touch control circuit on the touch sensors may be reduced.

  • Patent number: 8963366
    Abstract: A system for reducing electromagnetic noise generated by common mode currents in electrical connections of a power inverter and battery in an electric or hybrid electric vehicle. A pair of spaced apart electrical conductors extends along the vehicle chassis and electrically connects the power inverter to the battery. An electrically conductive metal plate is positioned in between the spaced apart electrical conductors. This metal plate is electrically connected to the chassis adjacent at least both of the power inverter and the battery/motor. Besides this, more connecting points are required to keep the distance between two points less than half wavelength of the maximum frequency of EMI requirements, and most preferably this metal plate is electrically connected to the chassis all the way with infinite connecting points. The metal plate is positioned so that the metal plate is closer to the electrical conductors than the space in between the electrical conductors and the vehicle chassis.
