  • Publication number: 20240389931
    Abstract: A plurality of optical excitation ultraviolet light wavelength bands is scanned on a wound sample. The material sample exhibits optical spectral characteristics along the light wavelength spectrum. Excitation response wavelengths emitted by the wound sample are captured in response to the plurality of optical excitation ultraviolet light wavelength bands. The capturing is accomplished using an image sensor. Output values of a plurality of pixels of an image from the image sensor are measured. The image represents excitation response wavelengths captured by the image sensor. The measuring detects optical spectral characteristics of the wound sample, and the optical spectral characteristics are in response to the plurality of optical excitation light wavelength bands. An output signature indicative of composition of a condition of the wound sample is provided, wherein the condition of the wound sample provides a metric of wound monitoring.

  • Patent number: 12154480
    Abstract: A light emitter that operates through a display may cause display artifacts, even when the light emitter operates using non-visible wavelengths. Display artifacts caused by a light emitter that operates through a display may be referred to as emitter artifacts. To mitigate emitter artifacts, operating conditions for a display frame may be used to determine an optimal firing time for the light emitter during that display frame. The operating conditions used to determine the optimal firing time may include emitter operating conditions, display content statistics, display brightness, temperature, and refresh rate. Operating conditions from one or more previous frames may be stored in a frame buffer and may be used to help determine the optimal firing time for the light emitter during a display frame. Pixel values for the display may be modified to mitigate emitter artifacts.

  • Patent number: 12127074
    Abstract: In some implementations, a first computing device can send notifications at times that the first computing device is not in an expected location. A user of a second computing device can remotely configure an expected location for the first computing device, which may be a particular location for a certain period of time. During that time, the first computing device can monitor its own location and check whether it is within the expected location. If the first computing device unexpectedly leaves or fails to enter the expected location, the first computing device may transmit a notification to the second computing device. Similarly, if the first computing device loses connectivity with other devices, a server device may notify the second computing device that the location of the first computing device cannot be determined.

  • Publication number: 20240245346
    Abstract: Disclosed techniques include image analysis using skin wound factors. One or more skin wound images are obtained for an individual. The skin wound images provide light spectrum information that includes fluorescence and reflectance characteristics. The light spectrum information includes infrared thermal characteristics. Processors are used to analyze the skin wound images to determine metrics for skin wound factors, based on the light spectrum information. The skin wound factors comprise infection, inflammation, granulation, topology, and epithelialization. An epithelialization metric is included in determining skin wound topology. The skin wound topology comprises wound area, wound volume, wound depth, wound shape, wound edge definition, or wound topography. An output indicative of biophysical skin wound status is generated. The output is based on the analyzing of the skin wound factors. The output is augmented, based on analysis of the infrared thermal characteristics.

The first electrical switch is disposed within a lower portion of the tubular housing, the second electrical switch is disposed within an intermediate portion of the tubular housing, and the third electrical switch is disposed within an upper portion of the tubular housing. Each of the switches has an open state and a closed state. Motion of the first float relative to the first switch changes its state. Motion of the second float relative to the second switch changes its state, and motion of the second float relative to the third switch changes its state. Thus a two-float module may provide three level control signals.
