Abstract: An apparatus for storing data and supplying stored data. The apparatus comprises a support unit having a plurality of connectors for connecting to a plurality of data storage elements, and a plurality of data storage elements. Each data storage element is connected to one of the connectors. The apparatus also comprises a cable having a first end connected to the support unit and a second end connected to a main part. The main part defining a first space containing a portion of the cable, and a second space for containing the support unit. The support unit is movable between (i) a first position providing access to the data storage elements and (ii) a second position in which the data storage elements are located within the second space. The cable is a ribbon cable comprising power wires having a relatively large gauge and signal wires having a relatively small gauge.

Abstract: Data storage apparatus comprising a main housing containing an electric power supply, a panel supporting a plurality of electric connectors for connecting the power supply to other component parts of the apparatus and a plurality of units. Each of the units comprises a plurality of data storage elements and is mounted to slide from within the main housing to provide access to its data storage elements. The apparatus also comprises a plurality of cable modules each comprising a cable having a first connector at a first end connected to one of the units and a second connector at a second end connected to an electric connector on the panel. The cable modules also include a moveable rigid structure providing a barrier preventing manual access to the panel. The second connector is attached to the rigid structure such that movement of the rigid structure causes the second connector to be disconnected.

Abstract: In one embodiment, a bipolar cell (31) includes a cell boundary (32) that defines a cell active area (33), a first array of bipolar transistors (41) is formed within the cell active area (33) and configured for a first function. The bipolar transistors (42) within the first array (41) are parallel to each other. The bipolar cell (31) further includes a second array of bipolar transistors (61) formed within the cell active area (33) and configured for a second function that is different than the first function. The bipolar transistors (62) within the second array (61) are parallel to each other and oriented in a different direction than the transistors (42) in the first array (41).

Abstract: A programmable logic circuit (10) receives a single-ended input signal at a D input (12). An input gate (14) of the programmable logic circuit has a first input connected to the D input, and a second input connected to a D bar input (16). An internal reference (18,22) is programmed to receive a reference level at the D bar input via a programmable external pin (24,26). The internal reference programmed corresponds to the single-ended input signal received at the D input. The internal reference can be a VBB reference level connected to the D bar input providing a reference level to an ECL single-ended input signal on the D input. A CMOS single-ended input signal received at the D input requires a CMOS reference level programmed at the D bar input from the internal reference. An internal selector (72) is also used to select at a pin (76) the corresponding internal reference.
