摘要： An audio power unit is disclosed which provides an audio output and charges removable battery packs as well as providing a number of AC receptacles for powering other tools and the like when the unit is connected to a source of AC power. The unit can optionally also provide DC power. When the unit is connected to a source of AC power, the AC power drives the audio unit which may be a radio or a combination radio and CD player and the AC source also powers a charger which recharges a battery pack if a battery pack is inserted into the charger receptacle. If the unit is not connected to a source of AC power, the radio may be powered by a battery pack when it is placed in the charger receptacle. When the unit is connected to a source of AC power, a relay is opened to isolate the radio unit from the charger and battery pack. The unit has a unique protective frame structure that is connected to the housing of the unit.

摘要： An LCD controller (10) has a DMA unit (18) and a FIFO memory (20) for storing display data. The LCD controller also has a display data generator (26) that generates display information using a line of the display data stored in the FIFO memory in accordance with a predefined algorithm. A holding register (28) is connected to the display data generator and stores the generated display information. A multiplexer (34) selects for display either the data stored in the FIFO memory or the generated display information. The generated display information is selected when there is a bus overload indicating that the data stored in the FIFO may be erroneous.
