Abstract: A pulse oximetry measurement system uses a pseudo-random noise generator to stimulate one or more light emitting diodes (LEDs). The light amplitudes from these LEDs, after passing through a part of a body, are detected by a phototransistor or photodiode and digitized with an analog-to-digital converter (ADC). The digitized ADC light amplitude values are re-correlated with the outgoing pseudo-random noise stimulus. Spread spectrum techniques are known for their noise mitigation properties, and ability to pass multiple signals through the same medium without interference. Thus, these measurements can be performed substantially simultaneously with minimal interference from each other. The pulse oximetry measurement system correlates the measured light intensities using pseudo-random noise generation and phase division multiplexing, and computes the measured and correlated peak-to-peak detected light amplitudes to obtain a ratio between these light amplitudes for determining oxygen saturation in the blood, and may also be used for heart rate monitoring.

Abstract: A test fixture used to calibrate an electronic device is disclosed. The test fixture includes several modules positioned on a rack. The modules may include either a stimulus member or light-absorbing material. An actuator connected to an end unit is configured to engage any one of the several modules and transport the module from the rack to a location over the electronic device. At least one module can calibrate a touch sensor of the electronic device, while at least another module can calibrate a proximity sensor of the electronic device. In some cases, an additional module is configured to calibrate a touch sensor of a second electronic device, such as a previous generation of an electronic device or an electronic device having a different dimension. The electronic device can lie on a cradle that may be identified by a feature on the cradle, such as a magnet.

Abstract: A flame sensor detects the presence of a flame in a combustion system in which the flame emits light. The flame sensor includes a body connectable with the combustion system. A photodetector is supported in the body. The photodetector responds to light emitted by the flame and generates an electrical signal proportional to an intensity of the light. A window is supported in the body and located between the combustion system and photodetector. The window is susceptible to contamination from the combustion system and the contamination may decrease sensitivity of the photodetector. A light source is supported in the body. The light source emits light so that a predetermined amount of the light emitted by the light source reflects into the photodetector when contamination is present on the window and the photodetector generates a signal indicative of contamination on the window.
