  • Patent number: 9962109
    Abstract: A portable hand-held spirometer is disclosed for use in taking respiratory tests and storing and displaying test results. The configuration of the spirometer includes handgrips that are positioned to ensure that the user is properly positioned to provide maximum breathing required for valid test results to be obtained. The spirometer also includes a progressively illuminated indicator that can be viewed by the user during a test to provide an indication in real-time to the user of the expected/desired duration of the exhalation or inhalation test. The indicator is completely illuminated only when the measured accumulated volume of air passing through the spirometer equals a predicted volume determined based on the age, gender, height, weight and ethnicity of the user stored in the spirometer. The structures and arrangement of a turbine assembly and sensors is also disclosed. Further, a method of receiving, storing and displaying information on the spirometer via a color touch screen display is also disclosed.

  • Patent number: 8488167
    Abstract: A computerized chart recorder is revealed, comprises a signal conversion unit, an operation control unit, a printing control unit, and a database. A signal conversion unit receives measurement signals of a measurement instrument, and converts the measurement signals to signal conversion data. A operation control unit receives the signal conversion data required for printing, produces corresponding chart data, and prints the curve of signal variations, which can be also displayed on a human-machine interface unit. Whether to store the data or to print can be determined. Besides, the data can be also transmitted to a printing control unit. When the printing control unit is activated, it can receive the chart data and the quality assurance data, and control a printing unit to emulate the chart recorder for executing chart recording. In addition, the quality assurance data can be printed as well for complying with the requirements of the quality-assurance operations.

  • Patent number: 4423412
    Abstract: A compact ribbon-indicator and chart-recorder instrument for use in process control systems adapted to indicate and simultaneously record the values of up to three independent process variables. The motive power for each pen/indicator drive system is supplied from a corresponding relatively high-speed stepping motor. Each such motor is servo-controlled by a feedback circuit including a potentiometer coupled to the pen drive cable for developing a d-c feedback signal to be compared with the d-c measurement signal. The system is arranged to actuate the motor immediately upon development of a deviation signal outside of a fixed dead-band, but the extent of initial motor movement is limited to a pre-set small amount (preferably one step). If the deviation signal still is outside of the dead-band after a predetermined period of time, a clock pulse oscillator is turned on to actuate the motor at a relatively rapid rate until the deviation signal returns to the dead-band.

  • Patent number: 4345258
    Abstract: A projection and display system utilizes a modulated laser beam whose energy distribution in the "P" and "S" polarization planes is controlled by a half wavelength retardation plate. The laser beam is then deflected along the X and Y axes and passes through a dichroic polarizer cube which splits the beam to focus upon a P channel smectic liquid crystal display cell and an S channel smectic liquid crystal display cell to selectively form images on one or both of the display cells. At the same time, the formed images are projected by the use of light that is split into two colored light beams by a second dichroic cube and is reflected to back light the images in each of the display cells. The projected beams then pass back through the first dichroic cube where they are recombined and passed through a projection lens system to a suitable display screen. To selectively erase the information on either of the display cells, an AC bias is applied to that display cell during the laser scan thereof.

  • Patent number: 3961334
    Abstract: A high-speed, permanent recording, multicolor projection display system in which the beam of a pulsed Argon laser is selectively deflected and focused to burn the desired images in a metalized film record medium which is back-illuminated for projecting the recorded images as they are produced. A channel selector polarizes the laser beam in either of two planes; each polarized channel is then selectively deflected and is focused through a dichroic/polarizer cube that transmits one channel and reflects the other channel to the metalized films in the focal planes where images are formed by the thermal action. Simultaneously with the recording action, the images are projected by the use of white light that is split into two colored light beams by a second dichroic cube and is reflected to backlight the images in each of the metalized films.

  • Patent number: 3958240
    Abstract: Sequentially generated pulses are applied to respective groups of alarm and status condition responsive contacts. A memory is indexed in accordance with the pulses to store individual condition signals received from respective contacts in each group and activate alarm or status indicators. A lock switch operates facilites for partially disabling a manual acknowledge switch which turns off audible and blinking alarm indicators. A printer records the time and a character indicating the specific alarm contact which was activated. Alarm summary command or alarm status summary command switches may be selectively operated to produce a print out of all alarm conditions or a print out of all alarm conditions and the status of all status contacts. The system employs modular units which may be selectively connected in the system to provide lamp annunciator functions and/or printing functions for selective sized groups of contacts.
