Abstract:

A multi-piston pump is provided which uses microprocessor controlled check all valves to control flow rate of a fluid at the pump's outlet port. The pump includes nine cylindrical shaped chambers and associated reciprocating pistons which are driven by a cam attached to a shaft. The pump's shaft is coupled to the shaft of a motor which, in turn, drives the pump's shaft and cam resulting in a fluid, such as seawater, filling each of the nine chambers and then having the fluid forced from the chamber by the movement of its associated piston from bottom dead center to top dead center. A pressure transducer which monitors the pressure at the pump's outlet port and a shaft encoder which monitors the angular position of the pump's shaft respectively provide analog signals indicative of the pump's outlet port's pressure and the shaft's angular position. A microprocessor receives these analog signals in a digital form, processes the signals and provides digital pulse signals to either extend or retract the rod of nine solenoids depending upon the pressure at the pump's outlet port. Each of the nine solenoid rods when extended engage a check ball valve within one of the pumps nine inlet passageways allowing the passageway to remain open when the associated reciprocating piston is in a pumping stroke.

Abstract:

A piezocone for measuring the soil's resistance to penetration and pore water pressure while being advanced into the ground by a rig. The piezocone includes a friction sleeve and a conical tip attached to the lower end of the sleeve. The conical tip develops the cone resistance. The friction sleeve is an isolated cylindrical sleeve which measures the resistance of the soil as the sleeve passes through the soil. The pore water pressure is measured by a porous element mounted in the conical tip of the piezocone and a pressure transducer mounted in the cylindrical friction sleeve of the piezocone. The measurements including pore water pressure, cone resistance and soil resistance are supplied to a computer which includes a Piezocone Dissipation Analysis program for processing data from the measurements to generate dissipation curves for each depth at which the piezocone provides hydrogeologic site characterization data. Soil classification is also provided from a data file stored within the computer. The Piezocone Dissipation Analysis program generates a Hydrostatic Pressure Profile curve and a Hydraulic Conductivity Profile Plot.

Abstract:

A patient transfer stand is provided for assisting a wheelchair-bound person to transfer to and from a wheelchair to a variety of other points in a simple fashion. The transfer stand includes a rotating base. The base includes 2 substantially rectangular cut out portions that accommodates the wheels of the wheelchair. The base supports a pair of vertical support bars, in addition to an elevated handle structure that the wheelchair-bound person can hold onto during transfer. The elevated handle structures include elastic straps which may be used to assist the wheelchair-bound person from the wheelchair into the patient transfer stand. A patient, if required, may utilize the elastic straps attached to a belt or harness worn about the waist to assist them in assuming a standing position inside the transfer stand. Through the utilization of developed leverage, the patient may assume a raised or semi-standing position in the transfer stand without assistance. The patient may also use hand holds or handles while they are assuming the standing position.

Abstract:

An electronics circuit for use in determining the position light is incident on a position sensing detector. The position sensing detector provides a pair of photoelectric current signals which indicate the position the light is incident on the detector. These photoelectric current signals are converted to negative ramp voltage signals by a dual switched integrator and then provided through a first pair of sample/hold amplifiers to a second pair of sample/hold amplifiers with each of the second pair of sample/hold amplifiers storing for one line of a raster scan the dark current voltage component of one of the photoelectric current signals. Each dark current voltage component, which is a positive voltage, is summed with a negative direct voltage component of the one of the negative ramp voltage signals by a pair of summing/integrating amplifiers which then integrate the summed signals to provide first and second positive ramp voltage signals indicative of the position of the light on the position sensing detector. The first and second ramp voltage signals are next converted to equivalent digital signals by a pair of analog to digital converters.
