Title: Diversity reception system
Inventor: FITZGERALD SHANE MICHAEL
IPC: H04B7/08
Filed: 1998-11-10
Abstract: A diversity reception system for use in narrow-band radio frequency communication system includes a plurality of receivers (102), that each generate a detected signal (110) from a received radio frequency signal. The diversity reception system switches between receivers (102) to output a high quality audio signal (202). The system selects a receiver having the highest quality reception at any given time by using a detected signal having the highest relative signal-to-noise ratio and a detected signals have less than a preselected threshold signal-to-noise ratio and a detected signal having the highest relative signal strength when one or more of the receivers is generating a detected signal having a signal-to-noise ratio at or above the preselected threshold signal-to-noise ratio.
Patent CA-2310491-A1 (CA)
Inventor: ISABELLE STEVEN H
IPC: G10L21/02
Filed: 1999-09-22
Abstract: Noise is suppressed in an input signal that carries a combination of noise and speech. The input signal is divided into signal blocks, which are processed to provide an estimate of a short-time perceptual band spectrum of the input signal. A determination is made at various points in time as to whether the input signal is carrying noise only or a combination of noise and speech. When the input signal is carrying noise only, the corresponding estimated short-time perceptual band spectrum of the input signal is used to update an estimate of a long term perceptual band spectrum of the noise. A noise suppression frequency response is then determined based on the estimate of the long term perceptual band spectrum of the noise and the short-time perceptual band spectrum of the input signal, and used to shape a current block of the input signal in accordance with the noise suppression frequency response.

Abstract: -31-   A coil car has a pair of deep center sill that is shallow over the trucks, a nd deeper at a mid span loaction between the trucks. The deep center sill supports a trough structure for carrying generally cylindrical loads, such as coils of steel. Cross- bearers extend outwardly and away from the center sill to attach to side sills. The trough structure has three parallel, longitudinally extending troughs - a central trough lying between two laterally outboard outer troughs. Each trough is shaped to  cradle steel coils, or other similar loads, between its inwardly and downwardly sloping shoulder plates. The shoulder plates are lined with cushioning to buffer coi ls during loading or travel. The outboard troughs are mounted above longitudinally extending stringers and are carried at a greater height relative to top of rail than t he central trough. The car has coil stops to discourage longitudinal shifting of loaded  coils. The coil stops have rollers to facilitate repositioning during loading, and a mi d- span step and hand grabs to facilitate climbing over the coil stop by personnel walkin g along the trough structure.
