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.

Abstract: To provide accurate reconstructable records of the events and therapy administered during a cardiac arrest, flow sheets are attached to the top of a timing clipboard. Each row of the flow sheet matrix indicates a different event and the columns indicate the time of events. The clipboard illuminates columns at intervals in the range of fifteen seconds to five minutes in a timed sequence across the flow sheet by energizing electroluminescent trips underneath the flow sheet to permit the nurse to indicate the events in the column corresponding to the time of the event. Other sensed data is recorded on a tape with timing signals for later reconstruction. When all of the columns have been covered, an alarm is sounded so that a new flow sheet may be attached. The page of the flow sheet is indicated on the clipboard for translation onto the flow sheet.

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.

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.

A first laser beam polarized in a first plane and a second laser beam polarized in a second plane is projected into a polarizer cube wherein the first laser beam is reflected to a record medium to record images thereon and the second laser beam is transmitted through the polarizer cube. Polarization and deflecting means located in the path of the transmitted second laser beam changes the polarization of the second laser beam to the polarization of the first laser beam and reflects the second laser beam back into the polarizer cube wherein the second laser beam is reflected in a direction opposite to that of the first laser beam to enable the second laser beam to function as a pointer.

Abstract: This disclosure obtains printing and displaying of information stored as a pattern of orifices in a colored liquid film established on the interstices of a screen-mesh member. A laser beam is used to effect removal of the film at each selected interstice either by puncturing the film thereat or vaporizing a portion thereof so that reactive surface tension force displaces the remainder of the film. The screen is moved in coordination with the writing thereon of the information pattern so that the area upon which the information is established may be presented sequentially to a displaying station and to a printing station. At the displaying station, light is either transmitted through the orifices established in the colored liquid film or is reflected from the film left in the unwritten interstices onto a display screen as a pattern of information either as a positive or a negative image of the actual information content established in the screen-mesh.

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.

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.
