Abstract: Various embodiments of the invention, therefore, provide enhanced devices for the measurement of a pressure of a bodily fluid, as well as methods of using and/or manufacturing such devices. In one set of embodiments, for example, a device for measuring a fluid may comprise an inlet port, which may be configured to be in fluid communication with a bodily fluid. Merely by way of example, in a particular set of embodiments, the inlet port may be in fluid communication with (and/or may comprise and/or be incorporated within) a needle designed to be inserted (e.g., subdermally) into a subject (such as a human and/or animal patient).

Abstract: A ball testing device having a compact housing with a microphone for receiving the sound generated when a ball strikes a surface and generating output signals. An electrical circuit in said housing is configured to receive the output signals and process the signals to determine the time lapse between the first and second and the second and third successive bounces of the ball and provide the ratio of time lapse between the second and third bounces to that of the time lapse between the first and the second bounce to provide the coefficient of restitution of the ball. Said housing including a display for displaying the coefficient of restitution.

Abstract: An apparatus (12) for providing information about the power and position of a high laser beam includes a heat absorbing body (46) having a target area within which the laser beam is directed. Position information is provided by a plurality of thermocouples (46) connected in series in a circular array and located radially outward of the target area. In the preferred embodiment, the thermocouple array is divided into four quadrants (60-66), each quadrant generating a voltage proportional to the heat flow in the body at that location. A comparison of the voltages generated by each of the quadrants will provide information about the position of the laser beam with respect to the quadrants. In addition, by summing the output of the quadrants, information about the total power of the beam can be derived.
