  • Patent number: 6195581
    Abstract: The invention is directed to a method of evaluating the signal of an infrared thermometer for measuring human body temperature, in which the infrared thermometer includes a probe adapted to receive thereon a probe cover or protective film sufficiently transparent to infrared radiation, and in which on a measuring operation performed with the probe cover or protective film in “installed” condition the signal is evaluated, so that a measuring operation is performed also when the probe cover or protective film is not installed, with an appropriate allowance being made for the consequently more intensive infrared radiation by different signal evaluation.

  • Patent number: 6149297
    Abstract: The invention is directed to a method of operating a tympanic thermometer, in which a sensor (8) for detecting infrared radiation is arranged in a housing (1) having a radiation inlet (23). Associated with the sensor (8) is an electronic evaluation unit (13). For temperature measurement, the radiation inlet (23) is covered with a probe cover (5) transparent to infrared radiation. The condition of a missing probe cover (5) is indicated by an audible warning signal or a signal lamp (14) which are activated after the thermometer is turned on.

  • Patent number: 4932121
    Abstract: The invention is directed to a long-hair trimming device for dry shaving apparatus, with a cutting comb arranged fast with a housing and having an abutment surface for engagement with an abutment surface of a cutting blade which is coupled to a carrier body via at least one driving member, the carrier body being adapted to be driven by a drive means, and with at least one pressure spring bearing with one end against the carrier body while its other end takes support upon the housing, wherein the carrier body provides on the side close to the cutting teeth of the cutting blade a slightly protruding seating edge made of a plastics material and having its cross-sectional profile tapering in the direction of the cutting blade, wherein the seating edge rests against the cutting blade in the area of the root of the cutting teeth, and wherein an optimum abutting engagement of the cutting blade with the cutting comb is accomplished by deformation of the seating edge and the cutting blade by means of the force the pre
