    摘要: A thermally controlled storage space system (10), such as for the dashboard (40) of a vehicle (12). The system (10) has a housing (22), which is configured to couple a portion of the vehicles air control system (48), such as a heating system, a ventilation system, or an air-conditioning system. A heat exchanger (26) is coupled to the housing (22) and to a thermoelectric device (28). A temperature sensor (62) generates a temperature signal indicative of the temperature within the housing (22). A controller (18), which is coupled to the thermoelectric device (28), adjusts the temperature within the housing (22) in response to the temperature signal.

    摘要: A differential direct current (DC) offset compensation circuit for providing DC offset compensation to a circuit device (110). The DC offset compensation circuit (100) comprises a differential integrator (120) and a summing network (130). The circuit device (110) is one of several types of devices, such as a DC coupled amplifier. The differential input (112) of the circuit device (110) is suitable for coupling to a differential input source (140) and the differential output (114) of the circuit device is suitable for connection to a load (150). The differential integrator (120) features a transconductance amplifier (18) at least one other amplifier (13), and a capacitor element (16) having a capacitance of C1. The summing network (130) sums the differential integrator output with the differential input signals of the differential input source (140) and cancels DC offsets of the differential input source (140) and the circuit device (110).

    摘要: This invention relates to an educational and recreational device which, in one preferred embodiment, includes a directional guidance system mounted in a plane substantially perpendicular to the horizontal. The system defines a continuum of directional guide paths leading from a substantially horizontal guide path element, at its upper end, into a descending S curve, then through a first complete loop of a helical coil, and terminating at a desired exit point on a subsequent loop. The tangent to the exit point is selected to any desired angle with the horizontal. The guidance system is adapted to control the direction of motion of a spherical mass in its travel through the system and to place it into a ballistical trajectory after leaving the system. A catcher, positioned in the line of flight of the spherical mass, retrieves the mass at any selected point along the trajectory. In another embodiment the complete loop of the helical coil lies in a plane substantially parallel with the horizontal.

    摘要: A differential transconductance amplifier consisting of a bipolar differential amplifier (110) and an active load circuit (120) for the bipolar differential amplifier (110). The transconductance amplifier is suitable for driving a load (130). The active load circuit (120) comprises a bipolar differential amplifier (140), a metal-oxide-silicon (MOS) amplifier (150), and a resistor R1. The active load circuit (120) generates active load currents IAL1 and IAL2. The output of the transconductance amplifier are the differential output currents I1 and I2 which are supplied to the load (130). Differential output currents I1 and I2 are the sum of the currents into the nodes between the bipolar amplifier circuit (110) and the active load circuit (120). The gain of the transconductance amplifier is controlled by a current source that biases the differential amplifier (110).

    摘要: A peak and valley measuring circuit (40) featuring a single digital-to-analog converter (DAC) (100), a peak counter (110), a valley counter (120), and a comparator (130). The peak and valley measuring circuit (40) uses the peak counter (110) when detecting peaks of the recovered audio signal and the valley counter (120) when detecting valleys of the recovered audio signal. The DAC (100) is used in conjunction with one of the counters (110) or (120) depending on whether peaks or valleys are being detected, and is preferably a current-mode DAC.
