A circuit for programming the inflation and deflation of a five segmented balloon pump as used in circulatory assist blood pump systems is disclosed. The rising and falling edges of wave pulses are used by a volume transducer to create a volume signal corresponding thereto. Means are provided to produce a plurality of signals corresponding to the rising edge of the waveform and a plurality of signals corresponding to the falling edge thereof. These signals are used to activate the various valves…

The invention relates to phototubes and in particular to photo multiplier tubes such as those associated with scintillation crystals and which are provided with an array of conductor elements juxtaposed with respect to the photo cathode of the tube and which when subjected to voltage pulsing in a scanning sequence are capable of providing information concerning the spatial distribution of light incident on the photo cathode.

A bowler’s wrist support has a rigid core member curved longitudinally and laterally to cover both the wrist and back of the hand and having fastening bands and fastening members for securing the wrist support over the upper and lower portions of the back of the hand and over the wrist portion.

The novel electronic metal coin analyzer is disclosed wherein a coin to be analyzed falls through an inductance coil which is coupled to the resonance circuit of an oscillator. As the coil falls through the coil, a dynamic change in inductance is produced in the coil and a resultant dynamic change of operating frequency of the oscillator occurs. Specifically, for each coin, a band or plurality of frequencies will be generated as the coin drops through the coil. These frequency signals are furthe…
