摘要:
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.

A two-piece hard shell case with a silicone or other flexible component may protect devices that hinge, slide, or otherwise articulate. A front surface hard cover may snap or connect to the front of the device while a back surface hard cover may snap or connect to the back of the device. A flexible component may be held in place under one or both of the hard shell pieces. The flexible component may be held under one or both of the hard shell covers and may have button pushers, covers, or other features to allow a user to operate a protected device while still covering the device.
摘要:
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.
摘要:
A protective case for an electronic device may have flexible components in impact areas, such as corners of the case, where the case may be designed to flex. In many embodiments, a gap may exist between the protective case and the electronic device, and impact to the case may be absorbed by the protective case before damaging the electronic device. In some embodiments, the protective case may be manufactured from a two shot molding process where a hard plastic case may have overmolded thermoplastic elastomer. Some embodiments may have two case portions that may be joined to enclose a device. Other embodiments may be a single case that snaps over a device. Still other embodiments may be a permanently attached cover that attaches using fasteners or snap features.
摘要:
A rigid removable case for a portable electronic device may have an acoustic isolation mechanism between the rigid removable case and an acoustic component on the electronic device. The acoustic isolation mechanism may be a compressible component that may provide an air seal between an interior surface of the removable case and an exterior surface of the electronic device. The acoustic isolation mechanism may be constructed of several different materials and several different manufacturing processes.
