Abstract: A display tool box includes a base having a receiving area with a plurality of recesses defined therein so as to receive tools in the recesses and an operation area having a hole defined therethrough which has a toothed inner periphery for a ratchet member rotatably engaged therewith so that a tool, such as a box end wrench is mounted to the ratchet member and can rotate the ratchet member.

Abstract: A Voltage Range Detection Circuit (VRDC) (8) determines the supply voltage range of the integrated circuit. In general, voltage detector (10) determines the voltage level of supply voltage V.sub.DD and stores the result of this determination in storage (12). Resistor network (14), which receives the stored result, configures itself in the proper resistor configuration for the determined supplied voltage such that a compare signal is generated that represents a Variable Low Voltage Detection (VLVD) switch point. Resistor network (14) outputs this generated VLVD switch point signal to a first input of comparator (18) to be compared with the constant level reference voltage output by voltage reference (16) at a second input of comparator (18). When the output of resistor network (14) drops below the reference voltage provided by voltage reference (16), comparator (18) outputs a reset signal to disable the chip because a low voltage condition has occurred.
