Title: System and method for detection and removal of dental tartar
Inventor: KARAZIVAN NAIM
IPC: A61B5/00
Filed: 2002-03-21
Abstract: A dental tartar detection and removal device (10) comprises a powered tartar removal instrument (12) adapted to be displaced along a tooth (T), illumination means (14) for illuminating with an incident light a region on the examined or periodontal site, detection means (16) for collecting the light reflected thereat, and an analysing system for providing a signal to an operator (OP) of the tartar removal instrument (12) or to the tartar removal instrument when measurements on the reflected light in one or more predetermined ranges of wavelengths fall within any first predetermined range of values that are characteristic of tartar, or when said measurements do not fall within any second predetermined range of values that are characteristic of artefacts other than tartar. As a result of the signal, the removal instrument becomes actuated, either by the operator (OP) or automatically, and the operator can proceed to removing the detected tartar (S) without having to remove the detection device, whereby detection can be continued while the tartar removal instruments (12) is in a tartar removal position, and until all tartar (S) has been removed.

Inventor: MCMICHAEL JOHN P
IPC: G16H20/10
Filed: 2002-07-24
Abstract: A method, system and apparatus for use in treating a patient receiving a biological substance, such as a cancer vaccine, to optimize therapy and prevent an adverse response. This system employs surrogate markers or indicators including blood levels of the vaccine to determine the next required dose for a patient. Since the surrogate markers may be employed as a percent change in status, virtually any indicator can be used. Surrogate markers could include any measure of the effectiveness of the vaccine's action. Given the effectiveness of the vaccine's action relative to the surrogate markers, a change in vaccine dose is calculated by the system.  Conversely, by employing this system, one could determine the expected result of the vaccine dose change on the surrogate markers.

Patent CA-2459620-A1 (CA)
Inventor: JOHNSON JEFFREY C
IPC: B05B7/14
Filed: 2004-03-04
Abstract: The present invention is directed to a powder paint delivery method and apparatus employing a pressurized reservoir pump that supplies a controlled stream of densely fluidized or dense phase powder paint to the applicator though a powder delivery conduit.      The powder flow rate is a function of the pressure in the reservoir and the flow resistance from the reservoir to the applicator, and is therefore very stable over time, and simple to control. The powder flow can be controlled by holding the resistance of the powder flow path constant and varying the pressure in the reservoir, or by holding the reservoir pressure constant and varying the resistance of the powder flow path.

Inventor: TABEI KENJI
IPC: H04N9/07
Filed: 2003-03-26
Abstract: A video signal processing apparatus that performs an appropriate knee processing to suppress occurrence of false colors and occurrence of line inconsistencies in density, thereby providing desirable video signals. The apparatus performs a knee processing of video signals having color components arranged for respective pixels in such a manner that a ratio of signal levels of at least adjacent ones of those pixels is maintained. In this way, when the luminance and color-difference signals are produced based on the result of the knee processing, both the luminance signal to be obtained based on the result of addition of the adjacent pixels and the color-difference signal to be obtained based on the difference between the adjacent pixels can be appropriately produced. Thus, even after a knee processing is performed, the hue of the color-difference signal can be maintained.
