Filed:

Oct 14, 1998

Appl. No.:

09/172545

Inventors:

Stephen J. Nichols - Madison CT
Cuong T. Luu - Kensington CT

Assignee:

Ahead Communications Systems, Inc. - Middlebury CT

International Classification:

H04L 12403

US Classification:

370449, 370395, 709100

Abstract:

A modified UTOPIA interface for inter-board applications is provided where the address timing generated by a polling master is extended to be two clock cycles long with no NULL address being driven onto the address line in between addresses. Output and input circuitry is provided in conjunction with the polling master and user ATM boards to accommodate hot insertion and to help drive the circuit. The master preferably includes an outgoing address latch and address latch control associated with the address bus, and a register associated with the enable signal. The master also includes a hot insertion buffer on the incoming cell available signal. The user device(s) include hot insertion buffers on the address bus, the data bus, and the enable signal. A remapping function is also preferably provided in associated with the user board which permits the user board to map received addresses into desired addresses. With the extended address timing and the provided circuitry, a workable inter-board hot-insertable UTOPIA interface is established.

US Classification:

187254, 188 711

Abstract:

An exemplary brake device includes a brake element configured to apply a braking force to resist rotation of an associated component. A mounting member is configured to mount the brake device to a stationary surface. The mounting member is at least partially moveable relative to the stationary surface responsive to a torque on the brake device. A sensor provides an indication of a force associated with any movement of the mounting member relative to the stationary surface responsive to the torque.
