Patent CA-2192428-C (CA)
Title: Storm water dispersing system having multiple arches
Inventor: MOORE ROY E JR
IPC: E03F1/00
Filed: 1996-12-09
Granted: 2001-05-01
Abstract: In a system for dispersing stormwaters beneath the earth surface, a pair of arch shaped molded plastic chambers (20) lie parallel each to the other upon a bed of gravel and are covered with soil.  A bridge cover (50) spans the space (36) between the sidewalls (28) of the adjacent chambers, to keep the soil above from entering.          Preferably, abutting base flanges (30) establish the chamber spacing which fits the bridge cover and also protect gravel at the bottom of the space from erosion. Stormwater is preferably delivered to the space (36), to then flow through sidewall perforations (29) into the chambers' interiors where it is stored and gradually dispersed into the earth.  Debris settles in the pocket (31) at the bottom of the space (36) and is removed by a perforated pipe (90) lying in the space.   Chambers have high aspect ratios, of 0.8 to 1 or more, and steep sidewall angles, of less than 15 degrees.

Title: Open air density separator
Inventor: GOBEL RICHARD J
IPC: D21B1/02
Filed: 1995-04-25
Granted: 2002-03-26
Abstract: A chamber (22) has an outlet (24) which opens downwardly to the atmosphere a nd an upwardly opening air return plenum (28). A duct (38) is inclined upwardly  at approximately sixty degrees to the horizontal, and a fan (32) mounted therein directs moving air (36) into the chamber (22). An upwardly inclined ramp (40) is positioned within the duct (38), and communicates between the chamber (22) and a downwardly opening discharge opening (46) in the duct (38 ). A metered supply of wood chips (52) is fed down a sixty degree incline (56) onto the ramp (40) through the air stream (36) which is moving through the duct (38). Lightweight chips (55) become entrained in the air (36) and are separated from the rocks, tramp metal and knots (50) which slide down the inclined surface (40) and exit through the opening (46) in the duct (38). Th e entrained wood chips (55), together with the air (36) from the fan (32), are  directed into a baffle (58) spaced within the chamber (22). By forcing the a ir (36) and chips (55) to move in a curved path, the baffle (58) separates the chips (55) from the air stream (36). As the air stream (36) expands into the  chamber (22), its velocity drops then passes through the chip stream (52) up  to the air return plenum (28). The chips (55), under the force of gravity, continue their downward flight, and exit the chamber (22) through the outlet  (24). An inclined ramp (40) with a slowly moving conveyor (168) may be used to avoid a build-up of material (50) on the inclined ramp (40).

Granted: 2001-06-05
Abstract: In accordance with the present invention, an RFID system has a homodyne receiver having two outputs; the in-phase or I output and the quadrature or Q output. The modulated baskscattered signal is composed of an information signal, modulated onto a single frequency subcarrier signal, generating a modulated subcarrier signal; this modulated subcarrier signal is then backscatter modulated onto the incoming RF signal. To demodulate this modulated backscattered signal, the Iand Q outputs are combined using an IQ combiner. This IQ combiner introduces a 90° phase shift, with respect to the frequency of the subcarrier signal, onto one of the demodulator outputs and then combines the outputs of the demodulator.

Title: System and method for one-way spray/aerosol tip
Inventor: PY DANIEL
IPC: B65D83/14
Filed: 1998-09-01
Granted: 2009-01-20
Abstract: A nozzle mechanism for generating an aerosol-type liquid discharge is provided, which nozzle mechanism ensures one-way movement of liquid during discharge and also has a substantially zero "dead volume" at the tip of the nozzle. The nozzle mechanism includes a flexible nozzle portion with an outlet and a fluid channel, a rigid shaft received within the flexible nozzle portion, and a rigid housing surrounding the flexible nozzle portion and exposing the outlet. The rigid shaft interfaces the outlet to form a first normally--closed, one-way valve, as well as to define a swirling chamber for collecting the liquid which has been channeled from the liquid reservoir, prior to being discharged via the outlet. The outlet has a tubular wall with thickness that decreases along the elongated axis of symmetry for the outlet toward the tip of the outlet. The fluid channel is circumferentially positioned within the flexible nozzle portion to create swirling action of the liquid delivered to said swirling chamber. Once the pressure on the swirling liquid reaches a threshold pressure sufficient to radially deform the portion of the outlet forming the first normally--closed valve, the liquid in the swirling chamber is discharged through the outlet. The nozzle mechanism is coupled to a flexible body portion which has a substantially tubular shape and a wall thickness which decreases from the bottom of the body portion toward the flexible nozzle portion. The rigid shaft received within the flexible nozzle portions extends down into the flexible body portion so that a second portion of the rigid shaft interfaces the flexible body portion to form a second normally-closed, one--way valve in the fluid communication path between the liquid reservoir and the swirling chamber.

Abstract: An improved non-linear processor used in echo cancellation eliminates a comfort noise source (214) and instead inputs a control signal (224) directly into a noise suppression system (403). The noise suppression system (403) uses the control signal (224) to inhibit the iterative update of the background noise estimate when the control signal (224) is active, which prevents any residual echo from biasing the noise estimate provided by the noise suppression system (403). Additionally, the control signal (224) is used by a gain calculator (533) within the noise suppression system (403) to attenuate each frequency band to the maximum allowable amount plus the current residual channel signal-to-noise ratio (SNR). Depending on the implementation, the noise suppression system (403) models the background noise of either a user of the PSTN or a user of a mobile station.
