摘要： A charging apparatus with multiple charge stations is disclosed. The apparatus includes a single power supply which operates under the control of a microprocessor to charge a plurality of battery packs disposed in respective charging stations. Associated with each charging station is a wiring harness assembly which includes an EEPROM memory chip having one or more stored charging algorithms for the type or types of battery packs to be charged at that charging station. The microprocessor reads the charging algorithm from a charging station's memory chip when a battery pack is inserted in the charging station. The microprocessor utilizes a feedback control loop including a resistor network to regulate the charging current and charging voltage supplied to each battery pack being charged. If a plurality of Li-Ion battery packs are disposed in respective charging stations, each pack is sequentially charged such that the voltage across the pack is raised to the rated output voltage of the pack. Then, all of the Li-Ion battery packs are charged in parallel until each is fully charged. The parallel charging reduces total charging time.

摘要： A hand held data entry apparatus wherein a main body portion is formed to be held in one hand while data is entered through a keyboard by the fingers of the other hand. An optical scanning head is mechanically and electrically connected to the main body portion through an arrangement which permits the optical scanning head to be connected to the main body portion in more than one relative position. The scanning head sensor is pointed in a direction such that when the device is held in one hand the other hand may be utilized for entering data through the keyboard and at the same time the scanning head is directed toward the surface to be scanned, without need to reposition the main body portion.
