Patent CA-2396455-A1 (CA)
Inventor: BEERENDS JOHN GERARD
IPC: H04R29/00
Filed: 2000-12-11
Abstract: According to an objective measurement technique for determining the quality of an output signal (X(t)) of an audio or voice signals-processing and/or -transporting system, the output signal and a reference signal (Y(t)) are mapped on representation signals (R(X), R(Y)) of a suitably chosen perception model. A differential signal (D(t)) of the representation signals is averaged, in a time-averaging device (17), in two steps by two averaging members (31, 32) connected in series, over time, whereby a quality signal Q is generated. The time averaging is carried out by the first and second averaging members at the local and the global levels, respectively, using various averaging functions, e.g., preferably Lebesgue p-averaging functions having various p-values p1 > p2. Advantage: a high correlation between a generated quality signal Q and the human quality perception, even in the event of brief disturbances.

IPC: B05B3/04
Filed: 2001-03-13
Abstract: A spray cleaner (10) is provided for rotatingly cleaning an interior of a vessel or the like. The spray cleaner has a main body (12) and a rotating spray body (14). The main body is at a proximal end of the spray cleaner, and the rotating spray body is at a distal end of the spray cleaner. An internal flow conduit (22) in the main body of the rotating spray body communicates a fluid inlet in the main body to a plurality of spray nozzles (18) in at least one spray head which is a part of the rotating spray body. A drive train (30) for rotating the spray body is positioned in the main body, such that the flow conduit passes around the drive train in an annular passage coaxial with the drive train, providing cooling thereto. A vaned rotor (26) in the flow conduit is connected to an input shaft (28) of the drive train, which transfers torque to an output drive system (42) that is fixedly connected to the rotating spray body. The rotation of the rotating spray body relative to the main body about a longitudinal axis of the cleaner effects rotation of the at least one spray head about a radial axis of the cleaner. A planetary gear set (36) may be used as the drive train.

Abstract: In a TDD wireless communication system between transmitters and associated receivers, automatic gain control of a receiver is only applied during the corresponding time slot within the TDD signal time frame architecture.  Successive received signal strengths are measured and gain levels are stored as estimates for an initial gain level in future time slots of the TDD signal.  Estimating techniques, such as averaging or trending of received signal strength over successive time slots, and averaging or trending of gain level settings, provide improved estimation of future initial gain levels.

Title: Multi-mode lighter
Inventor: TUBBY BRIAN
IPC: F23Q2/36
Filed: 2001-10-29
Abstract: The present invention relates to a lighter (10), which a user actuates by at least two different modes of operation. In the first mode, a biasing member (42) is positioned to oppose movement of an actuating assembly (33) so that a user releases fuel and ignites the lighter (10) only if a high-actuation-force is applied to the actuator. In the first mode, the lighter resists operation by unintended users by requiring a user to have a predetermined level of strength to actuate the lighter. In the second mode, the biasing member (42) is moved to a different position which does not oppose movement of the actuating assembly (33) to the same extent as the first mode so that a user may release fuel and ignite the lighter (10) if a low-actuation-force is applied to the actuator.
