摘要:
In embodiments of display viewing detection, a presence module, implemented on an electronic device, enables a first sensor to detect an object responsive to detecting audio via one or more microphones of the electronic device. The first sensor generates data that is used by the presence module to determine that the object is within a viewing range of the electronic device and that movement of the object is below a predetermined threshold. The presence module then enables at least a second sensor to confirm the object is viewing a display of the electronic device. When the object is detected by the second sensor, the presence module enables the display for viewing by the object.
摘要:
A radiation clinical thermometer for making no-contact measurements of the temperature of the eardrum, comprising a light receiving section (17) for receiving only infrared rays radiated directly from the eardrum and/or its vicinity, a signal processing means (4) for calculating the temperature from the output of the light receiving section, and an annunciation means (18) for annunciating the calculated temperature. Because the thermometer is not influenced by the heat radiation from other than the eardrum and/or its vicinity, the temperature variation of the probe (1) does not cause measurement errors and therefore an accurate temperature measurement can be made. When viewed at the cross section of the thermometer including the optical axis of the light collecting element, the infrared light receiving element is placed in a triangle formed by three lines connecting three points, and an intersection between the optical axis of the light collecting element and an optical path where a line drawn from the edge of the light collecting element in such a way as to be tangent to the inner wall of the probe on the same side as the edge of the light collecting element with respect to the optical axis extends from an imaginary end where the line intersects the end surface of the probe and passes through the edge of the light collecting element on the same side as the imaginary end point with respect to the optical axis to reach an image point of the imaginary end point by the light collecting element. The remaining two points are two image points of the light collecting element at the imaginary end point.

A thermometer that enables the measurement of temperature from multiple body sites comprising a body portion that has a circuit configured to measure an IR signal and convert it into an output that accurately reflects body temperature and a switch in communication with the circuit. The thermometer also comprises a probe that has an IR window configured to accept an IR signal and an attachment mechanism coupled to the probe which comprises a generally circular hollow bore at its distal end, fastening members to engage the body of the thermometer and a pin at its proximal end for interacting with the switch on the body of the thermometer. When the attachment mechanism couples to the probe, the pin interacts with the switch in various positions and the circuit converts the signal based upon the position of the switch which position reflects the location from which the temperature measurement was taken.

Example sensor systems to detect a presence of a person at a loading dock are disclosed. An example sensor system includes a housing mountable to a support structure. An emitter is supported by the housing and is to emit a projection. An actuator is coupled to at least one of the housing or the emitter, where the actuator is movable between a first position and a second position relative to the support structure. The emitter is to emit the projection along a first path when the actuator is in the first position and the emitter is to emit the projection along a second path when the actuator is in the second position. A receiver is supported by the housing at a substantially fixed location relative to the emitter proximate the emitter. The receiver is to receive a reflection of the projection reflected off of the person positioned within a line of sight of the projection.
