A coordinate sensor (10) includes at least two line sensors (1) that are disposed in x-axis and y-axis directions, and right-angle prisms (2) each of which changes a light path of light that has passed through an image display region of a liquid crystal panel (20). Each of the line sensors (1) is disposed outside the image display region and has a light-receiving surface (1a) parallel to an image display surface of the liquid crystal panel (20). The right angle prisms (2) cause light which travels in the x-axis and y-axis directions and which has passed through the image display region to be guided to the light-receiving surfaces (1a) of the line sensors (1). The coordinate sensor (10) receives the light which has thus passed through the image display region of the liquid crystal panel (20) so as to detect a coordinate, on the image display region, that is indicated by an object to be detected such as a finger. Consequently, a thin coordinate sensor that enables easy alignment with no reduction in aperture ratio and no restriction on operation speed can be realized at low cost.

Oversampling pulse oximeter
InactiveUS20050020894A1Increased complexityIncrease expensesDiagnostic recording/measuringSensorsDigital signal processingAudio power amplifier
An oversampling pulse oximeter includes an analog to digital converter with a sampling rate sufficient to take multiple samples per source cycle. In one embodiment, a pulse oximeter (100) includes two more more light sources (102) driven by light source drives (104) in response to drive signals from a digital signal processing unit (116). The source drives (104) may drive the sources (102) to produce a frequency division multiplex signal. The optical signals transmitted by the light sources (102) are transmitted through a patient's appendage (103) and impinge on a detector (106). The detector (106) provides an analog current signal representative of the received optical signals. An amplifier circuit (110) converts the analog current signal to an analog voltage signal in addition to performing a number of other functions. The amplifier circuit (110) outputs an analog voltage signal which is representative of the optical signals from the sources (102). This analog voltage signal is received by a fast A / D converter (112) which samples the analog voltage signal to generate a digital voltage signal which can be processed by the digital signal processing unit (116). The fast A / D converter (112) operates at a rate sufficient to take multiple samples per source cycle and may have a sampling frequency, for example, of over 41 kHz. The digital signal processing unit (116) implements software for averaging the samples over a source cycle for improved measurement consistency, improved signal to noise ratio and reduced A / D converter word length.
