Patent CA-2443439-A1 (CA)
Inventor: PERELLA STEVE L
IPC: G07C9/00
Filed: 2002-01-16
Abstract: Methods and apparatus for performing biometric indentification or verificati on of identities using optical spectroscopy of tissue. Tissue optical spectra c an be obtained by projecting optical radiation into skin and capturing the ligh t transmitted or reflected back and out through the tissue. The tissue spectra collected preferably includes primarily light that has passed through skin tissue below the epidermis. Multiple tissue spectra and identities can be collected from one or more individuals. These tissue spectra can be analyzed on a computer, and the spectral features that are most important for classifying person-to-person differences can be established using principle component analysis, linear discriminant analysis, or a veriety of other related techniques, One or more tissue spectra and identities can be collect ed from individuals for whom identification or verification may later be desire d. A target individual seeking identification or verification can submit a suitable tissue site for spectroscopic measurement. In addition a target individual seeking identity verification can submit a purported identity usi ng some means such as a typed user name, PIN code, magnetic card, transponder, etc. Similarity between the target spectrum and the spectrum or spectra in t he enrolled spectraldatabase with respect to the inter-person classification spectral features is determined and identification or verification is grante d based on the degree of similarity.

Abstract: A safety shut-off system controls power supply to an appliance to prevent accidental fires and the like. The shut-off system includes a shut-off switch for connection in series with the power supply of the appliance. A controller opens the switch in response to detection by the detector of a prescribed fire condition. Failsafe means are provided on the controller for opening the shut-off switch in response to a malfunction of the detector to ensure that the appliance is only permitted to operator under safe conditions when the detector is properly operating. In order to avoid false alarms the detector may take various forms including the detection of sound or other conditions which may be indicative of a potential fire. There are also incorporated switching capabilities to control additional a/c outlets, gas, propane and other appliances which work in unison with this system.

Title: Process and facility for removing metal contaminants from fertilizer streams
Inventor: GANSLEY RAYMOND R
IPC: C05G5/23
Filed: 2002-11-26
Abstract: A process and system for producing fertilizers with reduced levels of contaminants, and particularly a flue gas scrubbing process and facility that produce a fertilizer byproduct which is treated to remove heavy metals originally present in the scrubbed flue gas. The process entails contacting a flue gas with a scrubbing solution to remove acidic gases and produce a byproduct containing a fertilizer compound precipitate and dissolved metals and/or metal compounds. A fertilizer solution containing dissolved fertilizer and dissolved metals and/or metal compounds is then produced by adding water to the byproduct, after which the pH of the fertilizer solution is adjusted one or more times with a gaseous and/or liquid alkali to form precipitates of one or more metal species. The precipitates are then removed from the fertilizer solution and the solution dewatered to yield a fertilizer product with lower contaminant levels.

Title: Adjustable progressive joint-brake system
Inventor: KUPFER STEFAN
IPC: A61B19/00
Filed: 2003-02-25
Abstract: A joint (52) for connecting arm portions (40, 42) of a ceiling or wall mounted support system includes housing members (60,62) with an annular bearing (64) interposed between opposed surfaces (82,84) thereof. The housing members are clamped together on an axle (98) such that a braking force generated between the bearing and the housing member surfaces opposes rotation of one arm portion relative to the other. A variable braking force is generated between the bearing and surfaces (206) of the housing members which are generally perpendicular to the opposed surfaces (82, 84). The variable braking force is generated by a spring (182) and is greatest when the arm supporting a piece of equipment (24, 26, 28, 56) is at its lowest point, relative to the horizontal.  This overcomes the increased forces in the spring which otherwise tend to cause the arm portion (42) to drift upward.
