International Classification:

H04B 7/216

US Classification:

370335, 455524, 375130

Abstract:

The present invention provides a base station architecture that is modular in configuration, lowering the initial cost of implementing a new CDMA telecommunication system for a defined geographical region while allowing for future capacity. The scalable architecture is assembled from a digital base station unit that is configured to support a plurality of simultaneous wireless calls connecting to a conventional public switched telephone network. For initial startup, two base station units are deployed for redundancy in case of a single failure. Additional base station units may be added when the need arises for extra traffic capacity. If sectorization is required, the base station units may be directionally oriented. Coupled to and remote from each base station unit are two amplified antenna modules that contain an omni-directional or an external directional antenna, a high power RF amplifier for transmitted frequencies and a low noise amplifier for received frequencies. A separate power supply module capable of supporting two base station units provides continued service in the event of a mains power outage.

Appl. No.:

7/947290

Inventors:

Richard D. Turner - Knoxville TN

Assignee:

Robertshaw Controls Company - Richmond VA

International Classification:

F16J 304

US Classification:

92 34

Abstract:

A condition responsive control device comprising a case, a controller carried by the case, a linkage system supported by the case and coupled to the controller, and a condition responsive linkage actuator. The actuator comprises a convoluted bellows having an anchor convolution hermetically fixed to a bellows supporting housing. An anchor convolution mounting face and a housing bellows support zone are bonded together to secure the bellows to the support housing so that the bellows operates the linkage and controller in response to pressure differentials.

Assignee:

E. I. DuPont de Nemours and Company - Wilmington DE

International Classification:

B60R 1906

US Classification:

293 88

Abstract:

An energy-absorbing device suitable as an automobile bumper using sinuous (corrugated), elastomeric ribs, which can be either attached to a connecting member at one end and unattached at the other end or unattached at both ends. These ribs buckle in a direction normal to the impact force and modulate that force.
