Patent CA-2447200-C (CA)
Title: Surge counter/detector apparatus, system and method
Inventor: MENDOZA ANTHONY-CERNAN
IPC: G01R31/08
Filed: 2003-10-28
Granted: 2012-01-03
Abstract: A surge counter/detector apparatus includes current sensors communicating with power lines to sense a surge condition. A trigger circuit communicates with the current sensors and outputs a first signal in response to the sensed surge condition. The trigger circuit is reset and enabled by a second signal in order to enable subsequent output of the first signal. A processor detects the first signal from the trigger circuit and responsively increments and displays a count value at a display. The processor provides the second signal having a first state to reset the trigger circuit and a second state to enable the trigger circuit. The processor includes a timer to vary a time between (a) detecting the first signal, and (b) resetting and enabling the trigger circuit.

Abstract: Red blood cells are purified by separating whole blood, such as by centrifugation, to form a red blood cell fraction and a liquid fraction. The whole blood can be defibrinated or treated to prevent coagulation prior to separation. Preferably, the whole blood is bovine blood. The red blood cell fraction is then diafiltered to purify the red blood cells. The purified red blood cells can then be lysed to form a lysate of purified red blood cells. The purified red blood cells and the lysate of purified red blood cells are suitable for use in producing hemoglobin blood substitute.

Abstract: L'invention concerne un procédé et un système permettant d'obtenir un modulateur sigma-delta (.SIGMA.-.DELTA.) adaptif avec une quantification à 1 bit améliorant le rapport signal sur bruit (SNR) d'un modulateur .SIGMA.-.DELTA.. Ce procédé consiste à produire un signal différentiel représentant la différence entre un signal d'entrée analogique x(n) et un premier signal de rétroaction adaptif z(n), l'amplitude du signal d'entrée analogique x(n) étant comprise dans une première plage [-a, +a]. Le signal différentiel est cumulé pour produire un premier signal cumulé représentant une accumulation du signal différentiel. Le premier signal cumulé est ensuite quantifié pour créer un premier signal numérique quantifié y¿0?(n). Sur la base du premier signal numérique quantifié y¿0?(n), un premier signal de sortie numérique z¿0?(n) est produit, de façon que l'amplitude instantanée du premier signal de rétroaction analogique z(n) soit sensiblement maintenue dans la première plage [-a, +a] et supérieure à l'amplitude instantanée du signal d'entrée analogique x(n). Finalement, le premier signal de sortie numérique z¿0?(n) est soumis à une conversion numérique-analogique pour produire le premier signal de rétroaction adaptif z(n).

Title: Microprocessor decoder frequency hopping spread spectrum communications receiver
Inventor: HEMMINGER RODNEY C
IPC: H04B1/69
Filed: 2003-06-25
Granted: 2009-12-15
Abstract: The present invention is directed to a frequency hopping spread spectrum transceiver. The transceiver includes a microcontroller (110); a transmitter (120) having a voltage controlled oscillator (122), a direct digital synthesizer (124), and a power amplifier (126); and a receiver having an amplifier (128), an IF amplifier (132), a demodulator (134), and a data slicer (138). When transmitting, the transmitter sends a preamble that allows the receiving device to detect the signal and lock to it to receive the data. When receiving, the receiver first scans all channels and sorts them based on a Received Signal Strength Indicator (RSSI) and then attempts to lock to the channel with the strongest RSSI value by first sampling the received signal to verify the preamble, then synchronizing to the bit edges of the received signal, then detecting the start of a Start Frame Delimiter (SFD), decoding bits to verify a valid SFD and then sampling data bits to receive the data.

Abstract: A quick change cutting link of saw chain for cutting wood comprises a base member adapted to be pivotally connected to other links of the saw chain. The base member comprises a seat surface. A cutting member comprising a cutting edge releasably engages the seat surface of the base member. The cutting member includes sintered and compacted particles of abrasion resistant material. In particular, in one design the base member seat surface has a first taper and the cutting member includes a surface having a second taper. The first and second tapers extend at an angle ranging from about 0.5° to about 45° relative to a direction of chain travel at a close tolerance effective to cause self-locking engagement of the first taper of the seat surface and the second taper of the cutting member surface. The close tolerance is characterized by variation in the angle being not more than about 1° and, in particular, not more than 0.5 °. The invention is also directed to the cutting member itself, including a design in which one of the cutting member and seat surface includes an inverted-L shaped protrusion and the other includes an inverted-L shaped recess for receiving the inverted-L shaped protrusion. The inverted L-shaped protrusion and recess may be designed so as to form a wedge. Also included is wood-cutting saw chain containing the inventive cutting link such as saw chain adapted for use on a chain saw, timber harvester and the like.

Title: Pallet conveyor with chain drive recirculating in a horizontal plane
Inventor: STRANGE DAVID M
IPC: B65G17/22
Filed: 2005-03-15
Granted: 2012-01-24
Abstract: A conveyor using a drive chain to drive pallets along a closed loop path on a track lying in a horizontal plane through inside and outside turns so that the conveyor may transport parts along non aligned stations. An advance and a return run extend parallel to each other and are closely spaced to minimize the floor space required. The drive chain is engaged by two spaced apart sprockets engaging a respective side of the drive chain, the sprockets mounted to the pallet on a pivoted bar spring biased to urge the sprocket teeth into engagement with the chain. The sprocket bar is pivotally mounted to one end of the swing bar which has an opposite end connected to the pallet to allow the chain and pallet to move together along the track and negotiate inside and outside turns. The chain is guided in a chain guide channel through inside turns, and on sprockets around the outside turns. A pair of friction brake rollers are included, each attached to one of the sprockets and are normally in firm contact with each other to brake the sprockets and carry the pallet along with the chain, which friction brake rollers slip when the pallet is arrested by a stop mechanism to be allowed to accumulate, the sprockets then able to rotate and the chain allowed to continue to circulate past the stopped pallet. The pallets extend alongside the chain and track to allow vertical mounting of parts on a side plate of the pallet or alternatively on a horizontal top plate. Alternatively, the swing bars can each be connected to the chain by one of a series of pins connected to the drive chain and pivotally received in the swing bar end in a synchronous nonaccumulating conveyor.
