  • Patent number: 5329874
    Abstract: A portable tennis score keeper designed to keep the set score in the game of tennis. The set score is most often the most disputed score in the game. This invention allows any one of the players to simply flip over numbered plates to reflect the progress of each team's set score. The score keeper is simple in design, and is small enough to allow every tennis player to have it as a standard item in their sports bag. The two sets of plates suspended from notches on both sides of an elongated support member have inverse color combinations to identify each of the teams. The numbers zero through six reflects the number of games each team can win in each set. The number six is the last plate and is the total number of games required to win a set. The first numbered plate bears the word "love" inside the zero, an indicia in historical tennis score keeping terms for zero.

  • Patent number: 5318362
    Abstract: A non-contact pyrometric technique is provided for measuring the temperature and/or emissivity of an object that is being heated by electromagnetic radiation within the optical range. The measurement is made at short wavelengths for the best results. The measurement may be made at wavelengths within those of the heating optical radiation, and the resulting potential error from detecting heating radiation reflected from the object is avoided by one of two specific techniques. A first technique utilizes a mirror positioned between the heating lamps and the object, the mirror reflecting a narrow wavelength band of radiation in which the optical pyrometer detector operates. The second technique is to independently measure the a.c. ripple of the heating lamp radiation and subtract the background optical noise from the detected object signal in order to determine temperature and emissivity of the object. Both of these techniques can be combined, if desired.
