Title: Release pull bar holster
Inventor: KEEFE DAVID
IPC: B60R11/00
Filed: 1999-08-13
Abstract: A storage holster designed to securely contain and provide easy access to a release pull bar that is used for unlocking a fifth wheel assembly of a transport truck. The holster comprises an elongated rectangular plate with a carrier projecting from one side of the plate. The carrier receives and supports a release pull bar and has an open end which commences at a point midway along the longitudinal axis of the plate. The closed and of the carrier terminates at the distal end of the plate and is provided with one or more holes to permit drainage of grease or oil that may be coated on a pull bar following use thereof. A pin, inserted through a hole in both the carrier and plate, works in combination with a padlock to function as a security and safety device to prevent the pull bar from being removed without authorization, or from maneuvering out of position when the truck is in transit.      Connected near the proximal end and on the same side of the plate is a narrow rectangular collar lined with a rubber grommet. The collar helps to stabilize the position of a release pull bar during storage and prevents it from vibrating in the holster during transit. The invention also provides a means with which to attach the holster to a support surface of the truck, generally in an upwardly angled orientation to permit insertion and retention of a pull bar.

Title: Adaptive dual filter echo cancellation
Inventor: TRUMP TOENU
IPC: G06F17/10
Filed: 1998-02-26
Abstract: A digital signal processor that is used for echo cancellation computations is disclosed, which includes parallel multiplier/adders, an input signal sample memory, and a plurality of accumulators for temporarily storing the results of the computations performed. Consequently, not all of the computational results have to be saved in an external data memory, which minimizes data transfer bottlenecks and significantly increases the computational efficiency of the digital signal processor. The adaptive filter coefficient updates can thereby be computed much faster, and the adaptive filter coefficients can be copied much faster from one filter to the other. The computational complexity of the digital signal processor is significantly less than that of prior digital signal processors.
