Patent CA-2165235-A1 (CA)
Title: Contactless electronic transpoder with printed loop antenna circuit
Inventor: MICHEL BISSON
IPC: H04B1/59
Filed: 1995-12-14
Abstract: A hand-held electronic transponder with a printed loop antenna circuit.  The antenna circuit is manufactured by depositing on a flat substrate a mixture of discrete conductive particles suspended in liquid, according to a predetermined  design.     When  the  suspension  medium evaporates, the conductive particles randomly touch one another to establish a conductive pathway.  The process can also be used to produce three-dimensional conductor patterns by printing layers of electronically conductive pathways interlaminated with dielectric films.  When the conductive pathways on two adjacent layers overlap, capacitor is created, whose capacitance is function of the surface area of the overlapping conductive pathways and the  thickness  of  the  dielectric  medium  between  the pathways.  The capacitor can be used to tune the antenna circuit to a predetermined frequency.  A resistor can also be introduced in the antenna circuit by adding to the suspension of conductive particles a quantity of particles having comparatively high resistivity.

Title: Rotary piston driving mechanism
Inventor: EDELL IRA C
IPC: A61B17/32
Filed: 1994-07-29
Abstract: A driving mechanism transforms continuous longitudinal reciprocation of a piston (3) in a chamber (2) into unidirectional rotation. The mechanism utilizes a closed wave-shaped groove (8) defined in either the cylinder (1) or chamber (2) and adapted to receive guiding members (9) projecting from the other of the piston (3) and chamnber (2). When the piston (3) is forced to move longitudinally in either direction, the groove (8) slides over the guiding members to force rotation. The apices (13) of the wave-shaped groove (8) are either contoured or provided with a gating structure (21) to assure that the guide members do not backtrack but instead move in one direction through the groove (8).

Title: Method and apparatus for video lumber grading
Inventor: JOHNSON EMERIC
IPC: G01N21/898
Filed: 1997-04-29
Abstract: A lumber video grading apparatus includes a vision system, processors, a gradingstation having visual displays, a storage and retrieval device, an identification device, and a timing system. The vision system may include cameras mounted proximate to a lumber transfer for optically acquiring real time images of exposed cut surfaces of lumber pieces conveyed on the lumber transfer. The processors process the real time images into individually identifiable retrievably storable images and also into visually displayable real time images. A selectable lumber grade is correlated at a grading station to selectable pieces of lumber on the lumber transfer. The displayable real time images or later retrieved individually identifiable retrievably storable images are displayable on a visual display at the grading station. The individually identifiable retrievably storable images are retrievably storable on, and selectively retrievably from, the storage and retrieval device. The identification device is for selectively applying an individual identifier to the selectable pieces of lumber on the lumber transfer. The timing system is for correlating the real time images to the selectable lumber pieces.
Patent CA-2204829-A1 (CA)
Inventor: SHANG ALAIN Z
IPC: H04B10/60
Filed: 1997-05-08
Abstract: An optical receiver comprises a photodetector for converting an optical signal incident thereupon into a corresponding electrical photodetector current and a current-mode circuit coupled to the photodetector for receiving the electrical current. The current-mode circuit is characterized by a very low impedance, low capacitance input. It provides an electrical output current corresponding to the photodetector current. This electrical output current is substantially independent of the input capacitance, in view of the very low input impedance and small voltage swings of the current-mode circuit. Consequently, the photodetector may have a relatively large area, which facilitates optical alignment of transmitters and receivers when the optical receiver is used in optical interconnects. The current-mode circuit may comprise a current conveyor, conveniently followed by a current-to-voltage converter and a thresholder for providing a digital output signal in dependence upon the photodetector current. Alternatively, the current mode circuit may comprise a sense amplifier providing directly a digital output signal varying in dependence upon the photodetector current.

Patent CA-2214740-A1 (CA)
Inventor: SCHMIDT GENE VAL
IPC: F02B75/22
Filed: 1997-09-05
Abstract: A crankcase breather valve for ventilation and pressure control within the crankcase of an internal combustion engine in which pistons stroke upwardly and downwardly in a synchronous movement. The valve is inserted into a breather hose which conducts gases into and out of the crankcase. The valve comprises a resilient valve member preferably an elastomeric umbrella-type seal spaced above a seal seat and forming a gap therebetween through which gases may flow either direction during portions of the pistons stroke cycle. The valve construction permits three operating modes: firstly to permit the egress of positive pressure gas out of the crankcase and through the gap while the pistons stroke downwardly; secondly, to permit the ingress of a small amount of gas back through the gap into the crankcase when the crankcase pressure changes from positive to negative; and thirdly to check further ingress of gas into the crankcase at greater crankcase suctions developed when the pistons are moving upwardly.
