Filed:

Mar 28, 2002

Appl. No.:

10/107821

Inventors:

Alan Roth - Austin TX 78756
Curtis Richardson - Taylor TX 76574

International Classification:

H01L 2940

US Classification:

257758, 257750, 257774, 257776

Abstract:

A structure for selectively programming interconnections between an input contact and an output contact segment in a multilayer semiconductor, comprising a first group of metal segments each being formed on successive layers of the semiconductor and being interconnected by vias, the first group including the output contact segment; a second group of metal segments each formed on successive layers of the semiconductor and being interconnected by vias, the second group including the input contact segment; and means for connecting a metal segment in the first group to a metal segment in a corresponding layer in the second group, thereby connecting the input contact to the output contact.

International Classification:

G11C015/00

US Classification:

365 49, 365168

Abstract:

A content addressable memory (CAM) having a plurality of ternary memory cells, each ternary half cell comprising an equal number of transistors of a p-type and an n-type, the p-type transistors being formed in a first well region and the n-type transistors being formed in a second well region, the wells having at most one p+ to n+ region spacing, the transistors being interconnected to form the half ternary CAM cell and wherein the interconnections for the cell is restricted to a silicon layer and a first metal layer and connections between said cell and external signal lines is restricted to at least a second metal layer.

Abstract:

Lubrication systems and methods for selectively lubricating bearings in a backup energy system (e.g., a compressed air storage system or a thermal and compressed air storage system) with an air/oil mixture are provided. The lubrication system may provide different levels of lubrication based on the operational status (e.g., standby mode or emergency power generation mode) of the backup system. For example, during periods of inactivity (e.g., standby mode), the lubrication system may intermittently apply the air/oil mixture to the bearings to compensate for oil burn-off and to ensure efficient transfer of power during backup power system startup. When the backup system is activated, the lubrication system may continuously apply the air/oil mixture to the bearings at a rate determined by the loading on the backup system.
