  • Handheld electromonitor device
    Patent number: 5873990
    Abstract: An apparatus is disclosed which is a microprocessor based instrument designed to conveniently and rapidly measure various analytes in environmental and biological samples. The instrument operates as a stand-alone unit powered by a battery or a DC power module and may be equipped with a communication port allowing uploading test results to a computer. Several unique electronic, microchip and software configurations were developed for the device to make it a portable, low-cost, safe, automated and simple-to-operate instrument particularly adapted for precise and accurate measurement of metal ions such as heavy metals such as lead in human blood.

  • Counter for fluid dispensers
    Patent number: 5622163
    Abstract: The disclosure is of a device for indicating the number of fluid dispensations remaining in a container for holding and dispensing metered quantities of the fluid. The device is a hermetically-sealed unit which is assembled with the dispenser portion or component of the container and includes microprocessor means for maintaining an inventory of the doses or dispensations remaining of a predetermined number of dispensations. Indicator means signals when the predetermined number of dispensations reaches a level before empty.

  • Personal spirometer
    Patent number: 5137026
    Abstract: A self-contained portable spirometer includes a housing and an air tube with an orifice. Within the housing there is a transducer and microprocessor-based circuitry for generating standard exhaled air performance measurements such as forced expiration volume and peak expiratory flow rate, commonly referred to as FEV.sub.1 and PFER. These measurements are displayed on a screen disposed on the housing. Since the air tube has a non-linear response, two amplifier stages with different amplification are coupled between the transducer and the microprocessor. The microprocessor monitors the flow rate through the tube and selects the signal from either one or the other amplification stage depending on the flow through the tube. The microprocessor also monitors the flow to determine when no air is blown through the tube. In this latter case, the computer shuts the power to the analog circuitry to conserve power.
