摘要： An electric switch assembly for use with a magnetic reed switch includes a trigger that is movable with respect to a housing between an open position and a closed position and that includes a trigger magnet. The switch assembly further includes a second magnet, fixed relative to the housing, that is located adjacent the first magnet when the trigger is in the open position. The magnets are oriented such that their magnetic fields tend to cancel each other when the trigger is in its open position. This provides an increased disparity in the magnetic field reaching the magnetic reed switch between the open position and closed position and eliminates the need for precision alignment and individual adjustment of the magnetic reed switch at the point of manufacture.

摘要： A secondary battery boost system which includes a primary power supply for a computing device, and a secondary power supply for the computing device. The boost system also includes a boost circuit operative to increase the power output of the secondary power supply applied to the computing device. Upon the output of the primary power supply falling below a level suitable for properly powering the computing device, the boost circuit feeds the computing device power from the secondary power supply. The boost circuit also boosts the power output of the secondary power supply so that the secondary power supply can be smaller and more light weight.

摘要： A charging system monitors the rate of change in battery voltage, adjusts the rate of charging, and checks the changes in battery voltage following adjustments in the rate of charging to observe a predetermined sequence of voltage changes that signifies when a battery is fully charged. The charging system determines the slope between consecutive battery voltage measurements. The charging system charges a battery at the full battery capacity in response to positive or zero voltage slope measurements and reduces the charging rate in response to negative voltage slope measurements. A nickel-cadmium battery is fully charged when at least one sequence of a negative slope, followed by a decrease in charging rate, then a positive or flat slope, followed by an increase in charge rate, and finally another negative slope is observed.

摘要： A single button contrast control which can bi-directionally adjust a contrast function in one of two directions so as to increase or decrease the contrast of a display. An interrupt generator generates an interrupt for each user activation of a single button control key. A control circuit incrementally adjusts the contrast function in accordance with the interrupts generated. If no interrupts are generated within a predetermined period of time following a previous interrupt, the control circuit changes the direction in which the contrast is incrementally adjusted so that the next time a user activates the single button control key the control will be adjusted in the other direction.

摘要： A monitoring circuit for a Li-Ion battery pack charging apparatus is disclosed. The monitoring circuit modifies charging time for a Li-Ion battery pack inserted in the charging apparatus to compensate for temperature effects on the charging current input to the battery pack. In one embodiment of the monitoring circuit, a comparator is utilized to compare a voltage across the battery pack, V.sub.charge, to a set point voltage value, V.sub.sp. The set point voltage value, V.sub.sp, is taken off a temperature sensor circuit comprising a voltage divider circuit. The voltage divider circuit includes at least one thermistor in a ground connected leg of the divider. In a second embodiment of the monitoring circuit of the present invention, a differential amplifier is coupled to opposite ends of a low resistance sensor resistor. The sensor resistor is coupled between charging circuitry and the Li-Ion battery pack to be charged. The voltage differential across the resistor, V.sub.sensor, is amplified by a gain of the differential amplifier. A gain adjusted differential voltage, V.sub.gsensor, is compared by a microprocessor to a set point voltage value, V.sub.sp. The set point voltage value, V.sub.sp, is generated by a temperature sensor circuit. The temperature sensor circuit includes a voltage divider circuit and the set point voltage value, V.sub.sp, is taken off the voltage divider which includes at least one thermistor in a ground connected leg of the divider.
