摘要： A chemochromic sensor includes multiple bi-directional LEDs, each optically aligned with one or more test areas. Each LED is used as both a light emitter when driven in forward bias, and as a light detector when driven in reverse bias. By alternating the bias on the LEDs, multi-way light measurements of the test area can be obtained.

摘要： A method and apparatus determining an intensity of light flux. First, a photodiode or LED is charged by reverse-biasing to a fixed voltage. The fixed voltage is a sum of a threshold voltage and a predetermined offset voltage. Then, a time to discharge the photodiode to the threshold voltage by a photo current is measured to determine an intensity of light producing the photocurrent.

摘要： An apparatus measures a fluid level in a container. A light source emits a light beam. A light sensor can sense the light beam. An optical conduit is arranged in a container for holding fluid. The optical conduit is arranged between the light source and the light sensor along a path of the light beam, such that at least one part of the light beam passes through the optical conduit, and at least an other part of the light beam passes through the fluid when the container holds the fluid. The sensor senses the light beam when a level of the fluid coincides with the one part of the light beam passing through the optical conduit, and the sensor does not sense the light beam when the level of the fluid coincides with the other part of the light beam passing through the fluid due to internal reflection at the fluid level.

摘要： A user interface is configured to detect an attempt to touch a virtual button. The interface includes a first concave mirror facing a second concave mirror. The second concave mirror includes an aperture. A physical control button is arranged proximate to the first mirror and aligned such that an image of the control button in a form of a virtual button appears at the aperture. An attempt to touch the virtual button is detected, and feedback is generated at the virtual button in response to detecting the attempt to touch the virtual button by a user.

摘要： An optical communications transceiver includes an LED coupled in series with a resistor. A microprocessor has one I/O pin connected to the LED. In a first mode or transmit mode, the LED is periodically driving in forward bias to emit light to transmit data. In a second or receive mode, the LED is periodically not driven in reverse bias, e.g., reverse bias or zero bias. Then, the LED is allowed to change charge of the capacitance of the LED's junction using a photo-current. The change in charge is measured using a timer. When the change in charge exceeds a predetermined threshold, input light is sensed. Thus, the LED can be used to receive data in the second mode.

摘要： A telephone handset dynamically buffers a real-time audio signal. The handset includes a microphone and a speaker connected to a telephone network interface. A proximity sensor is located near the speaker of the handset. The proximity sensor is connected to a circuit for measuring a coupling between the handset and an ear of a user. A buffer continuously records the real-time audio signal. The recorded signal can than be played back after the handset is first removed from the ear of the user, and second re-applied with the ear of the user using a time-compressed audio signal, until the playback signal is resynchronized with the real-time audio signal.
