Patent CA-2272401-A1 (CA)
Title: Multi-electrode and needle injection device for diagnosis and treatment of muscle injury and pain
Inventor: HUBBARD DAVID R
IPC: A61B5/296
Filed: 1997-11-20
Abstract: A multi-electrode and needle injection device for identifying and treating muscle pain using two simultaneous electrode EMG recordings to locate an active trigger point. The two electrodes are displaced so that one electrode detects EMG activity at the trigger point and the other one detects EMG  activity adjacent to the trigger point, within the same muscle. The combination of the electrodes with a drug delivery system allows the user to inject a medication locally at the trigger point to block the trigger point activity and reduce or eliminate muscle pain. The electrodes are on a hypodermic needle. The needle is used to facilitate both the location of the trigger points and for treatment, by injecting a drug into the trigger points.
Patent CA-2272524-A1 (CA)
Inventor: VIITANEN MARKKU
IPC: D21H23/78
Filed: 1999-05-21
Abstract: The present invention relates to a method and arrangement for feeding a treating agent to an apparatus (1, 2) employed in the treating of a paper or board web for applying the treating agent to the surface of the web being treated. In the method treating agent is prepared and then supplied to the apparatus used for applying the treating agent, into the applicator chamber thereof, wherefrom the treating agent is further applied to a moving surface. The treating agent is first supplied into a feed chamber (2) communicating with said applicator chamber, and the feed chamber (2) is provided with a shunt line (10, 11) serving to remove the excess amount of the treating agent supplied to said feed chamber (2) that is not adhered to said moving surface. A pressure measurement signal at a point (22) representing the internal pressure of said feed chamber is obtained, and the feed pressure of the treating agent is adjusted to a value causing the internal pressure of the feed chamber to attain its desired set value.

Title: Cochannel signal processing system
Inventor: DOGAN MITHAT CAN
IPC: H04B7/08
Filed: 1996-11-26
Abstract: A method and apparatus for processing cochannel signals received at a sensor array (110) in a cumulant-based signal processing and separation engine to obtain a desired set of output signals (38) or parameters. For use in a signal recovery system, the output signals are recovered and separated versions of the originally transmitted cochannel signals. An important feature that distinguishes the cumulant-based system from other signal separation and recovery systems is that it generates an estimated generalized steering vector associated with each signal source, and representative of all received coherent signal components attributable to the source. This feature enables the invention to perform well in multipath conditions, by combining all coherent multipath components from the same source. In a receiver/transmitter system (316), the estimated generalized steering vectors associated with each source are used to generate transmit beamformer weight vectors that permit cochannel transmission to multiple user stations (310). The basic cumulant-based processing and separation engine can also be used in a variety of applications, such as high density recording, complex phase angle equalization, receiving systems with enhanced effective dynamic range, and signal separation in the presence of strong interference. Various embodiments and extensions of the basic cumulant-based system are disclosed.

Title: Methods and apparatus for making paint roller covers with thermoplastic cores
Inventor: HUMPHREY DENNIS D
IPC: B05C17/02
Filed: 1999-10-19
Abstract: Methods and apparatus for making paint roller covers by spirally wrapping a strip of hot thermoplastic film onto an exterior surface of a thermoplastic tubular form and spirally wrapping fabric strip having a thermoplastic backing onto the spiral wound strip of thermoplastic film while the thermoplastic film is still sufficiently hot to cause the thermoplastic film to flow into interstices in the fabric backing and permanently bond the fabric strip to the exterior surface of the tubular form. The tubular form may either comprise a plurality of preformed tubes or be formed by spirally wrapping a continuous length of core strip material around a mandrel while maintaining the adjacent edges of the core strip material in closely spaced, nonoverlapping relation to form a spiral seam between the core strip edges. In the latter case, the adjacent edges of the hot thermoplastic film may be overlapped outwardly of the spiral seam to provide additional adhesive at the spiral seam for flow into the spiral seam and into the interstices in the fabric backing outwardly of the spiral seam.

IPC: F23Q2/16
Filed: 2000-02-11
Abstract: A lighter safety system which in a first "safety on" position prevents the ignition of the lighter by not releasing gas when the trigger is pulled. The simultaneous downward depression of a safety switch with the operator's thumb and the rearward depression of the trigger by the operator's fingers (of the same hand) allows the lighter to ignite. A safety gas lever in the housing is pivotable when a positioning pillar in the housing is depressed. A yoke on one end of switch lever engages the neck of a gas nozzle. Depression of the switch lifts the nozzle to release gas. The simultaneous depression of the trigger activates the ignition system;  thereby igniting a flame.
