    Abstract: To detect a physical parameter such as pressure, temperature, acceleration or force, the physical parameter is allowed to influence the movement of a light transmitting piezoelectric member. Light is supplied to the member and the member is vibrated in a direction transverse to the light transmitted in the member. The vibrations of the member are modulated by the physical parameter. The modulations of the vibrations modulate the light transmitted by the member. The modulations of the light transmitted by the member are then detected to detect the physical parameter. In some embodiments the physical parameter causes nonvibrational relative motion between two flexible light transmitting members. The change in the amount of light transmitted between the two members is detected for detecting the physical parameter.

    Abstract: A type element interchange mechanism is incorporated into a high speed serial printer with rotary print wheel and linear carriage movement. A number of print wheels are selectively mountable onto a carriage, which carries a print wheel, print hammer, and print hammer solenoid, from one or more removable carousels, each carousel typically carrying several different type font print wheels. Print wheels are transferred directly between the carriage and a carousel, without the necessity of intermediate transfer mechanisms or steps, through the controlled linear translation of the carriage and the carousel. The print wheel-carrying carousel has a plurality of arms and is rotated to present the desired arm in position for transfer of a print wheel with the carriage. Microprocessor controls are provided so that print wheel changes are implemented automatically in response to input signals defining the desired font type. A computer controlled initialization program is provided which in addition to providing a startup and reset procedure also automatically identifies the print wheel identification numbers by reading coded slots located in the center hub of the print wheels.

    Abstract: To measure the heat transfer coefficient of a sample, an element with temperature sensitive optical properties is placed in contact or implanted in the sample. The element is heated or cooled. The temperature difference between the element and the unheated sample and the rate of heating or cooling indicate the heat transfer coefficient of the sample. In one embodiment, the element is heated or cooled at a constant rate. The heat transfer coefficient of the sample is then inversely related to the difference in temperature between the element and the unheated sample. Alternatively, the element may be heated or cooled at such a rate that the temperature difference between the element and the unheated sample remains substantially constant. The heat transfer coefficient of the sample then varies directly with the rate of heating or cooling. The heat transfer coefficient of a sample is a measure of its composition and other physical properties. The composition of gasses, liquids, the presence of bubbles in a liquid, and fluid levels can be detected by the optical technique. Pressure and flow rates of fluids can also be detected. The technique can be used also to more accurately measure the thermal conductivity and temperature of small objects with small heat capacities.

    Abstract: To detect a physical parameter, a resonator is connected to a body which changes in dimension when subjected to the parameter. Thus, when the body changes in dimension in response to the parameter, the resonance frequency of the resonator is modulated thereby. Such modulations are detected optically to detect and measure the parameter. In the preferred embodiment, the resonator transmits light and light is applied to the resonator so that the light supplied is transmitted through the resonator and so that the modulations of the resonance frequency also modulates the intensity of the light transmitted by the resonator. The modulations of the intensity of the light transmitted by the resonator is detected to detect the parameter.
