    摘要： An apparatus includes one or more sensors and a control unit. The one or more sensors may be configured to generate signals in response to movement of a vehicle. The control unit generally comprises (i) an interface configured to receive the signals from the sensors and (ii) a filter configured to reduce an effect that a mechanical transfer function of a housing of at least one of the sensors has on at least one of the signals. The filter may be configured to utilize a variable frequency band digital representation of the mechanical transfer function to negate the effect of the mechanical transfer function of the housing on the at least one of the signals.

    摘要： A method of interfacing a LC sensor with a control unit is provided. The control unit may include first and second contacts, where the LC sensor is connected between the first and the second contact. A capacitor is connected between the first contact and a ground. To start the oscillation of the LC sensor, the method may include during a first phase, connecting the first contact to a supply voltage and placing the second contact in a high impedance state such that the capacitor is charged through the supply voltage. During a second phase, the first contact may be placed in a high impedance state, and the second contact connected to the ground such that the capacitor transfers charge towards the LC sensor. During a third phase, the first contact and the second contact may be placed in a high impedance state so the LC sensor is able to oscillate.

    摘要： Provided is a sensor device wherein malfunction due to a negative surge is suppressed. This sensor device is provided with: a sensor element wherein electrical characteristics change corresponding to physical quantities; a signal processing circuit that processes output signals of the sensor element; a first transistor element that supplies currents to the sensor element and the signal processing circuit; a control circuit that controls a base current of the first transistor element; a power supply terminal; and a ground terminal. The sensor device is characterized in that the control circuit is provided with a limiting section that limits a current flowing from the ground terminal toward a base terminal of the first transistor element.
