Abstract: Provided herein is a biosensor for detecting a target analyte in a sample comprising a first and second photoelectrode each comprising conductive substrate and photoactive material, a first and second capture probe functionalized on the first and second photoelectrode, respectively, and optionally one or more reporter moieties comprising a detectable label, wherein the first and second capture probe each, independently, provides a distance between the detectable label and the photoactive material in the presence of the target analyte, wherein intensity of detection signal dictated by the distance is generated from the first and second photoelectrode by transfer of electrons between the detectable label and the photoactive material, wherein a higher, or higher increase than in absence of sample, in the intensity of the detection signal from the first as compared to the second photoelectrode in the presence of the sample, is indicative of the presence of the target analyte.

Abstract: This disclosure relates to a biosensor, and methods of use thereof, for detecting a target in a sample comprising a photoelectrode comprising a conductive substrate and a photoactive material; a population of capture probes functionalized on the photoelectrode wherein the capture probes are capable of binding to the target and a reporter moiety; and the reporter moiety comprising a detectable label and a capture probe binding portion; wherein exposure of the target to the population of the capture probes results in binding of the target to a fraction of the population which results in a decrease in detection signal intensity compared to the intensity in the absence of the target, and subsequent binding of the reporter moiety to the remaining unbound capture probes results in an increase in detection signal intensity that is less than an increase from the reporter moiety binding to capture probes not exposed to the target.

Abstract: An infant warming assembly includes a heater assembly having a heater surface temperature sensor, a skin temperature sensor, and a user interface to input a commanded skin temperature value. The skin temperature sensor and the commanded skin temperature value are used in controlling a temperature component of a control loop. The heater surface temperature sensor is used in controlling a power component of the control loop that powers the heater based at least in part upon the heater surface temperature sensor and a control signal from the temperature component.

Abstract: Methods for image content detection calculate (16), for a pixel, an estimated intensity of the pixel and calculate (17), for the pixel, an actual intensity of this pixel and detect (18) whether a function of the estimated intensity and the actual intensity fulfils an intensity condition and generate (19), in response to an intensity condition detection result, a pixel content detection signal. These intensities are functions of the color value of the pixel. These methods perform well for a blue content (sky like cloudy sky and non-cloudy sky) and are used for content based classifications and automatic selections of images. To improve an efficiency and/or a success rate, the methods may further detect (15) whether color values fulfill color conditions. The methods may further detect (32,33) whether functions of numbers of pixels from groups of pixels fulfill block threshold conditions, to be able to generate block content detection signals in response to block threshold condition detection results.

Abstract: Methods for image content detection check (15) color values of pixels via color conditions and check (18) pixels via edge conditions and check (22) functions of numbers of edge conditioned pixels and numbers of color conditioned pixels via ratio conditions and generate (23), in response to ratio condition detection results, block content detection signals. These methods perform well for green content (greeneries like grass, leaves of trees, bushes) and blue content (water like river water, sea water) and are used for content based classifications and automatic selections of images.
