摘要： A system having a sensor, a feedback loop comprising a controllable load and an integrator, and a comparator. The light filter is matched to the sensor to allow enough light to be sensed while appearing dark. Current produced by the sensor is received by the controllable load, across which a voltage is detected. Upon a relative change in light intensity, a difference between the detected voltage and a reference voltage is integrated by the integrator over an integration time to produce a feedback signal. The feedback signal completes the feedback loop by controlling the controllable load's impedance and adjusting the value of the detected voltage back to the value of the reference voltage. Thus, relative changes in light intensities are detected while thereafter adjusting to the ambient light conditions. When the difference between the detected voltage and the reference voltage is greater than a preset value, the comparator alters an output voltage. The altered output voltage indicates enough of a relative change in light intensity that the interactive device can appropriately respond to the new covered or uncovered sensor condition. The integration time may be reduced within the integrator when going to a brighter light intensity condition incident to the sensor to meet user expectations. Furthermore, a timer circuit may be used to reset the integration time by providing a reset signal to the integrator once a predefined period of time elapses after the sensor is covered or uncovered.
摘要翻译：具有传感器，包括可控负载的反馈回路和积分器以及比较器的系统。光滤波器与传感器匹配，以便在出现暗色时可以感测足够的光。传感器产生的电流由可控负载接收，检测电压。在光强度相对变化时，积分器在积分时间内积分检测电压和参考电压之间的差异，产生反馈信号。反馈信号通过控制可控负载的阻抗并将检测到的电压的值调整回参考电压的值来完成反馈回路。因此，在其后调整到环境光条件下，检测光强度的相对变化。当检测到的电压和参考电压之间的差值大于预设值时，比较器会改变输出电压。改变的输出电压表示足够的光强度的相对变化，交互设备可以适当地响应新的覆盖或未覆盖的传感器状况。当进入到传感器的更亮的光强度条件以满足用户期望时，积分器内积分时间可能会减小。此外，定时器电路可以用于通过在传感器被覆盖或未覆盖之后经过预定义的时间段来向积分器提供复位信号来复位积分时间。

摘要： A miniature high frequency power transformer comprises first and second "E" shaped ferrite core halves surrounding mating inner and outer modular transformer bobbins having formed thereon respectively the primary and secondary windings of the transformer. The inner and outer modular transformer bobbins are positioned such that the inner transformer bobbin is inserted into the outer transformer bobbin with the secondary windings surrounded by the primary windings. When assembled, the inner modular transformer bobbin has a protrusion that extends axially therefrom through the outer bobbin and terminates in first core retaining ears at one end of the transformer. Second core retaining ears extend from the opposite end of the transformer, and both ears receive the "E" shaped core halves, maintained in position on the transformer by bonding.

摘要： A method and apparatus for identifying a module installed in a base from a plurality of different modules and selecting a set of functions corresponding to the installed module. A preferred embodiment is the Intelli-Table™ toy that includes three modules, each of which can be installed into an annular channel in the base. When a module is installed, a unique pattern of recesses or flat surfaces on the bottom of the module is detected by a first set of switches in the channel. Based on the unique state of these switches, the base selects a set of functions corresponding to the installed module. Each module includes a plurality of different movable elements that activate a second set of switches in the base. Moving an element activates a switch, causing the base to perform a function unique to that element and to the module installed.
