Abstract:
A medical therapy machine includes: an enclosure; a medical therapy machine component located inside the enclosure; a video monitor supported by the enclosure and displaying at least one of information and indicia relating to the medical therapy; an ambient light sensor positioned with respect to the enclosure so as to be able to sense a level of ambient light impinging the enclosure; and a logic implementor configured to control a level of backlight brightness for the video monitor based on the level of ambient light sensed by the sensor.
Abstract:
The present invention provides a polymer blend for fabricating a laser-weldable article having a first component of a material not thermally responsive to a laser beam and selected from the group consisting of polyolefins, ethylene and lower alkyl acrylate copolymers, ethylene and lower alkyl substituted alkyl acrylate copolymers, ethylene vinyl acetate copolymers, polybutadienes, polyesters, polyamides, and styrene and hydrocarbon copolymers; a second component of a laser responsive material having low solubility in an aqueous medium and present in an amount by weight of from about 20 ppm to about 2000 ppm; and the blend being sufficiently thermally responsive to exposure to a laser beam having a wavelength within a range of wavelengths from about 700 nm to about 1500 nm to at melt upon exposure to the laser beam for a short period of time.
