Apparatus and method for simultaneous display of alphanumeric characters of variable character density on a raster scan CRT monitor is disclosed. Circuitry is provided to supply multiple sources of timing for terminal operations, to switch among timing sources without display degradation, and to vary the number of dots per raster line that constitute a character field. The density of displayed characters may be changed, under user control, for each character row.

Heartbeat data is measured and converted into a series of electrical output pulses, the frequency of which is related to the heartbeat pulse rate. The output pulses trigger 'on' and 'off' a timing device, and the average time of a heartbeat cycle is then converted into a heartbeat pulse rate and displayed. The timing device includes a means for delaying a first specified number of output pulses before beginning the sampling period and registering a count of clock pulses which represents the time period of a second specified number of the output pulses occurring subsequently to the first specified number of output pulses.

Respiration data is measured and converted into a series of electrical output pulses, the frequency of which is related to the respiration rate. The output pulses trigger 'on' and 'off' a timing device, and the average time of a respiration cycle is then converted into a respiration rate and displayed. The timing device includes a means for delaying a first specified number of output pulses before beginning the sampling period and registering a count of clock pulses which represents the time period of a second specified number of the output pulses occurring subsequently to the first specified number of output pulses.

Respiration data acquisition, conversion and display system

Medical data including temperature, respiration rate and pulse rate are measured and stored in an acquisition unit incorporating a circulating register for storing data covering many patients. An analog temperature signal is converted into binary coded decimal for visual presentation on a display of the acquisition unit. The display data is then stored in the acquisition unit memory by actuating a RECORD switch. An analog respiration rate signal and an analog pulse rate signal are also converted into binary coded decimal for sequential display and storage in the acquisition unit memory. Medical data from external sources may similarly be stored in the acquisition unit memory. This recording procedure is repeated for any number of patients desired up to the storage limit of the acquisition memory. Data stored in the acquisition unit is then transferred into a printer unit that accesses each memory location and prints the data on a separate label for each individual patient. The printer includes a hard wired minicomputer which reads in data from the acquisition unit and compares it with identifying codes for controlling a digital printer. Medical data for each patient stored in the acquisition unit is temporarily stored in a random access memory and sequentially compared with each of a plurality of identifying codes for control of the digital printer. After all patient data in the acquisition unit has been transferred into the printer memory, a signal is generated to enable clearing of the acquisition unit memory for subsequent use thereof.
