Abstract: A method of detecting a thermocouple short circuit in a medical device, including obtaining a first temperature measurement from a thermocouple of the medical device; obtaining a second temperature measurement from the thermocouple; calculating a rate of change over time between the first and second temperature measurements; comparing the calculated rate of change over time to a predefined rate of change over time threshold; and generating an indication of a thermocouple short circuit based at least in part on the comparison.

Abstract: In a color image sensor having alternating rows of photosensitive pixels of first and second patterns of spectral sensitivity to one or more of first, second, and third colors, the method of reading out the sensor comprising the steps of:reading out a group of three sequential rows of pixels, by combining the two rows having pixels of the same pattern of spectral sensitivity into a single read-out row of pixels and dumping the row of pixels having the different pattern of spectral sensitivity; andrepeating the readout step until the sensor is completely read out so that sequential readout rows of pixels read out from the sensor have alternating rows of pixels of first and second patterns of spectral sensitivity to one or more of the first, second and third colors, the sensor thereby being read out at a faster frame rate while preserving the color pixel pattern of the sensor.

Abstract: A method of displaying a color image on a color display comprising the steps of: providing a digital color image signal which is a matrix of pixels, each pixel having first, second, and third color components; for each pixel, determining whether or not two of the three color components are in saturation, and, if they are, setting the signal level for each of the two color components at the signal level of the other of the three color components; and displaying said color image pixel as a monochrome pixel.
