Abstract: A hand-powered apparatus and method for measuring and dispensing a predetermined volume of liquid. A predetermined volume of liquid is selected using a control knob on the apparatus and a valve is moved to a fill position. The handle on an attached hand pump is then moved alternately up and down causing fluid to be drawn into a measuring vessel. Further upward movement of the handle is prevented upon the fluid level in the vessel reaching the selected volume. Thereupon, the valve is moved to a dispense position whereby continued pumping of the handle is again possible. The handle is alternately pumped up and down causing the fluid to exit the vessel.

Abstract: In a system for transmitting two level data bursts on a fiber optic (FO) bus, a circuit for turning on a light emitting diode to an excitation level induced by a current I.sub.B corresponding to the knee of the diode characteristic curve and increasing the emitted light in response to a second increasing excitation current over a second portion of the curve beyond the knee extending from excitation level I.sub.B to excitation level I.sub.M. The circuit includes first logic for exciting the diode by the first current, a light responsive device for determining when the emitted light reaches the intensity represented by the knee of the curve and induced by I.sub.B, and logic for reproducibly storing I.sub.B. Second logic responds to the excitation of the diode to the knee of its curve to further excite the diode with the second excitation current until the diode emits a desired light intensity induced by I.sub.B +I.sub.M. Logic is provided for reproducibly storing a signal I.sub.M. Switching logic supplies the current I.sub.M to the diode in response to the data bursts and supplies I.sub. B to the diode substantially concurrently with the data bursts. In the absence of the data bursts the current level I.sub.B is reduced to substantially zero.

Abstract: Within a power supply circuit for a semiconductor laser, output current is maintained constant at each temperature level over an operating range and the magnitude of that constant current is varied directly with temperature to maintain the light output of the laser substantially constant over the operating temperature range. In the preferred embodiment, the negative temperature coefficient characteristic of the base-emitter junction voltage for bipolar transistors is utilized to compensate for the negative temperature coefficient characteristic of the light output from the semiconductor laser.
