Patent CA-2059785-A1 (CA)
Title: Three axis passive motion exerciser
Inventor: STEF FRANCINE
IPC: A63B21/005
Filed: 1992-01-21
Abstract: A three axis passive motion exerciser which moves the patient's foot in dorsal/plantar, valgus/varus and abduction/adduction movements. A microprocessor provides signals to control motors which drive cradles and a plate in the desired motions. Potentiometers provide positional feedback information about the actual location of the cradles and the plate, with series resistors providing feedback of the actual motor drive current values. The microprocessor monitors the positions of twa motions versus a master motion to keep the movements in synchronization. The movements are synchronized so that the end of the travel limit is reached for each axis simultaneously. The microprocessor further monitors the drive currents to prevent overcurrent conditions and the speeds to limit travel rates. A display and keyboard are-provided to allow the operator to monitor and change operating parameters, such as travel limits, force limits and session times.

Title: End caps for filter elements
Inventor: BOYLAN MICHAEL A
IPC: B29C65/08
Filed: 1992-04-14
Abstract: An end cap for a filter element comprises first and second concentric components of a thermoplastic material. The first of the components forms a side wall and a base of a peripheral groove of the end cap while the second of the components forms a second side of the peripheral groove. The first and second components are connected by a weld extending around the components in the region of the peripheral groove. The weld may be an ultrasonic weld. This prevents distortion of the components at high temperatures by strengthening the composite while allowing use of lightweight inexpensive components that have smooth sealing surfaces with no injection mould parting lines.

Patent CA-2073944-A1 (CA)
Inventor: PAIK WOO H
IPC: H04B3/06
Filed: 1992-07-15
Abstract: A method and apparatus are provided for adaptively equalizing data signals in a communications receiver. An unequalized data signal is demodulated. The demodulated data signal is filtered in an adaptive equalizer that initially updates adaptive filter coefficients using error signals derived from a first algorithm. A carrier lock signal is generated when a phase error of a filtered signal output from the adaptive equalizer reaches a threshold value. The adaptive filter coefficients are updated using error signals derived from a second algorithm instead. of the first algorithm in response to the carrier lock signal.    The first algorithm is a self-recovering equalization algorithm such as the Constant Modulus Algorithm. The second algorithm can be a decision directed algorithm. Carrier phase is recovered without the use of a phase rotator or phase derotator, by locating the adaptive equalizer inside of the carrier recovery loop. The invention is particularly adapted for use in the recovery of multilevel amplitude modulated data, such as QAM data.

Patent CA-2083708-A1 (CA)
Inventor: NADKARNI SADASHIV K
IPC: C22C32/00
Filed: 1991-05-22
Abstract: A process for producing unagglomerated single crystals of aluminum nitride having a size of at least 10 microns suitable for the reinforcement of metal, ceramic and polymeric matrix composite materials. The process involves reacting alumina (or a precursor) with carbon (or a precursor) under an atmosphere of nitrogen (or a precursor such as ammonia or an amine) at a temperature in the range of 1700 - 1950 ·C in the presence of an alkali metal oxide (or precursor such as a carbonate) as a crystal growth promoter or catalyst. The alkali metal oxide is present in an amount required for the formation of crystals of the required size, preferably in the range of 10 - 60 microns. Particularly desirable crystals are produced if electrostatic precipitator dust is used as a source of the alumina, if petroleum coke or calcined anthracite coal is used as a source of the carbon and if the reaction is carried out in the presence of a porosity enhancer for the reaction mass, especially short cellulose fibres. The particles produced by the invention are in the form of large single crystals for good matrix reinforcement and may have low oxygen and carbon contents.  Moreover, to reduce the oxygen content even further, the reaction mixture may be subjected to a preheating step under nitrogen at a temperature in the range of 1600 - 1700 ·C prior to further reaction under nitrogen at 1800 - 1950 ·C. The invention extends to the particles produced by the process and to matrix composites reinforced with the particles.

Abstract: An elastomeric sealing sleeve 6 is enclosed by an annular housing 1 which is split longitudinally and can be drawn together in the peripheral direction by means of a clamping screw 22. The clamping screw 22 passes with clearance through two U-shaped clamping members 16, 17 which are accommodated in clamping brackets 12, 13 fastened to the housing 1. The clamping members 16, 17 are supported with the ends of their legs on flat wall sections 12a, 13a of the clamping brackets 12, 13. The head 24 as well as a nut 25 of the clamping screw 22 bear against arched supporting surfaces 20a of the clamping members 16, 17. While the housing 1 is being drawn together, the clamping members 16, 17 can move relative to the shank 23 of the clamping screw 22, in the course of which the screw head 24 and the nut 25 can roll on the arched outer surface 20a. The screw shank 23 is therefore subjected to little or no bending stress.

Title: Three-Dimensional Maximum a Posteriori (Map) Tracking
Inventor: LO ALLEN K
IPC: G01S15/66
Filed: 1993-03-22
Abstract: An automatic  detection apparatus (20) and method (20a) applies the Short and Toomey algorithmic  processing procedure to a frequency and beam direction windowed and time segmented  set of FFT magnitude detected data, comprising time, frequency and beam direction data, to determine the presence or absence of narrowband lines indicative of target tracks.  This is achieved by storing the time, frequency and beam direction data, and then processing (32, 33) this data using a predetermined three-dimensional maximum  a posteriori procedure whereby individual target tracks associ-ated with each beam direction are concurrently processed, and whereby transitions are made between adjacent beam directions in order to process target tracks having a maxi-mum signal to noise ratio to provide for detection of a target (11).  An output target track is generated  by combining the high signal to noise ratio portions of the processed individual target tracks into a single output target track.  The present invention extends the tracking capabilities that are obtained using the Short and Toomey processing  pro-cedure from two dimensions  to three dimensions, and this added dimension provides spatial tracking in addition to spectral tracking.  The spatial tracking is performed con-currently with the spectral tracking in an array processor.

Title: Portable transit data display
Inventor: BURGENER EDWARD CARL
IPC: G08G1/123
Filed: 1993-04-06
Abstract: ABSTRACT Provides users with an accessible continuously updated arrival time estimate of the next vehicle arrival at vehicle stops, such as bus stops. Three discrete data streams are collected at a central computer and radio-beamed to portable receivers, each of which places some of the data in memory and uses some for real-time display, when the unit has been activated by the user. One stream allows time estimate to be computed; a second updates route changes; a third places cross-street data into unit memory, or displays storm warnings or the like. Users can enter specific stops and routes, can program audible pre-alert arrival warnings, can choose to be alerted to specific vehicle types (such as handicap accessible), and can see two arrival time estimates simultaneously, either for two different stops of different routes (to compute transfers) or of two sequential vehicles arriving at the same stop. The illustrated embodiment is solar powered.
