Abstract

A sensor, such as, for example, a gravity-responsive sensor, provides an output used to select an orientation of a display of a display device. For example, the output may indicate that the orientation of the display should comprise a portrait or landscape orientation, an orientation rotated, such as, for example, ninety degrees (90°), one hundred and eighty degrees (180°), two hundred and seventy degrees (270°), or the like. In addition, one or more manual switches, buttons, or display icons may be actuated or otherwise selected to manually set the orientation of the display.

Claims

1. A handheld noninvasive physiological monitor capable of an undocked portable configuration and a docked tabletop configuration, the monitor configured to accept detector signals from a noninvasive detector capable of detecting light attenuated by tissue of a patient, the monitor comprising:

a handheld portable housing including a processor, a user interface configured to allow users to configure programs to be executed on said processor, and a display, the processor configured to process detector signals and output values indicative of physiological parameters of a patient to the display, the display configured to display said output values in a plurality of display orientations, and the housing configured to at least mechanically dock with a tabletop docking station; and

a gravitational sensor included within said housing, the gravitational sensor configured to output an orientation signal indicative of an orientation of the housing,

wherein the processor includes at least two modes of operation, a first mode corresponding to when said housing is in a docked tabletop configuration and a second mode when said housing is in an undocked portable configuration, said first mode including an automatic determination of said display orientation responsive to said orientation signal from said gravitational sensor, and said second mode including manual determination of said orientation of said display through said user interface.

2. The handheld noninvasive physiological monitor of claim 1, wherein said automatic determination of said first mode is responsive to said manual determination of said second mode to override said signal from said gravitational sensor.

6. The method of claim 1, wherein displaying said display indicia comprises displaying a plethysmograph.

7. The method of claim 1, wherein displaying said display indicia comprises displaying blood oxygen measurement information.

8. The method of claim 1, wherein reorienting said display indicia with respect to the display according to said orientation signal from said gravitational sensor when said monitor is in a docked state further comprises reorienting said display indicia with respect to the display according to an orientation signal from one or more of a non-mercury sensor, a mercury sensor, and a tilt switch.

3. A method of reorienting a display of a physiological monitor, said monitor capable of an undocked handheld portable configuration and a docked tabletop configuration, said docked tabletop configuration corresponding to at least a mechanical mating of said monitor to a docking station, the method comprising:

outputting signals configured to drive emitters of a noninvasive sensor associated with a measurement site on a patient;

receiving signals indicative of physiological parameters of said patient from a detector of said noninvasive sensor, said detector configured to detect light from said emitters attenuated by tissue of said patient at said measurement site;

processing said signals to determine display indicia responsive to one or more of said physiological parameters;

determining a docking state of said monitor;

receiving an orientation signal from a gravitational sensor;

reorienting said display indicia with respect to a display, said display integral with said monitor, according to a manual selection when said monitor is in an undocked state; and

reorienting said display indicia with respect to the display according to said orientation signal from said gravitational sensor when said monitor is in a docked state.

4. The method of claim 3, further comprising overriding the reorientation of the display indicia with respect to the display of the physiological monitor when said monitor is in said docked state using a manual selection.

5. The method of claim 4, further comprising reorienting said display indicia of the display according to said manual selection.
