Abstract: A lock mechanism for a built-in connector (2) fixed in a casing (10) constituting a main body of a diagnostic apparatus, etc., to an external plug (3) connected to a cable of a measurement sensor, etc. The built-in connector (2) is fixed inside an open portion of a panel (11) of the casing (10) of the apparatus, and shutters (4; 6; 7) for closing the open portion (13) are disposed in front of the fixed connector (2) in such a fashion as to define an opening (12) for receiving the plug (3) between the front portion of the connector and the shutters (4; 6; 7). The plug is locked when its rear portion is engaged with cuts (41, 61, 71) formed at forward edges of the shutters.

Abstract: The present invention provides a method and apparatus for adapting to noise sources affecting a pulse oximeter. Various available frequencies are evaluated to determine their respective noise levels and one is selected to act as the operating demultiplexer frequency. During normal operation of the pulse oximeter, the various available demultiplexer frequencies are periodically scanned to determine which has the lowest associated noise. The noise level associated with the operating frequency is used to determine the signal-to-noise ratio of the pulse oximeter signals and thereby qualify certain signals from the pulse oximeter. Those pulses associated with a signal-to-noise ratio below a predetermined threshold are rejected and excluded from use in calculating blood oxygen saturation.

Abstract: A pulse oximeter which modifies the alarm condition when motion is detected. Basically, if the lack of a pulse is determined to be as a result of motion artifact, the generation of an alarm is postponed. In addition, the display indicates that motion is present and that the last reading is questionable due to the presence of motion. The invention also determines if motion artifact is present from the pulse oximeter detector signal itself. The ratio of the positive and negative peaks of the derivative of the pulse signal are compared to a motion/blood pulse threshold.

Abstract: A graphics coprocessor adapter with hardware support for horizontal scrolling is disclosed. A graphics processor provides both a row address with a RAS signal and a column address with a CAS signal to two banks of video RAMs. Both banks are provided with the same scrolling column address signal. Translating logic intercepts the column address signal for the static plane RAM bank and translates it into a fixed value. Thus, a single column address signal can control both the scrolling and static planes.
