摘要： Presented is a sensor that includes a magnetoresistive (MR) sensing device to sense a magnetic field and to produce an AC signal voltage proportional to the sensed magnetic field. The sensor also includes circuitry, coupled to the MR sensing device, to remove DC offset from the AC signal voltage. The DC offset may be related to the hysteresis characteristics of the MR sensing device. To remove DC offset, the circuitry may obtain an averaged DC offset and subtract the averaged DC offset from the AC signal voltage to produce a sensor output signal.

摘要： A limiting circuit for controlling overshoot in a charge current in a battery recharging system includes a current amplifier receiving input indicative of charge current in a rechargeable battery circuit and generating a current error signal, a voltage amplifier receiving input indicative of charge voltage in the rechargeable battery circuit and generating a voltage error signal, and a power amplifier receiving a first signal indicative of power in a switching voltage regulator and a second power signal indicative of power in the rechargeable battery circuit, and generating a power error signal. The limiting circuit compares the voltage error signal, the current error signal, and the power error signal to determine the error signal having the greatest value, and generates an input signal to a pulse width modulation comparator. The limiting circuit also includes an internal current source, a first transistor coupled to the current amplifier, a second transistor coupled to the voltage amplifier; and a third transistor coupled to the power amplifier. The first transistor, the second transistor, and the third transistor are coupled to the internal current source to determine the error signal having the greatest value. To prevent reverse current flow in the switching voltage regulator, a low current comparator receives a signal indicative of the current flowing in the switching voltage regulator, and generates an output signal. A transistor receives the output signal from the low current comparator, and generates a signal to maintain the current flowing in the switching regulator circuit above a threshold value.

摘要： A shiftable snare strainer for a snare drum including a body secured to the drum shell and a slide longitudinally shiftable relative to the body. The slide is connected at its lower end to the snares. A lock is pivotally carried by the body for engaging the slide to hold the slide in a down position wherein the snares are spaced from the head. The lock is released by striking a release pad to allow the slide to shift upwardly to engage the snares with the drumhead.
