  • Patent number: 10973456
    Abstract: This invention provides a non-invasive diagnosis system that is not only capable of producing high-resolution, three-dimensional images of abnormalities of tissue growth inside the body but, it can also detect the type of abnormalities and their location using multispectral imaging techniques. It is possible to provide a portable, non-invasive device that is handheld and with which a person may use to screen themselves for early detection of skin cancer without the need to visit a physician. As the present invention uses broadband sources and/or multiple coherent sources, secondary factors such as oxygen metabolism or blood volume associated with the cancer tissues could also be detected to provide further verification of the type. This invention would raise the accuracy of diagnosis and reduce the rate of false positives and false negatives.

The controller calculates one or more blood pressure values for the user based on the PTT.

    Abstract: A connectorized lighting system for a base structure such as a deck pad, comprising a base structure having an a retaining cavity disposed in and running along a surface of the base structure, a lighting element inserted into the retaining cavity, and connectorized light source that provides electrical power to the lighting element, exhibits a low profile, and may be removable and replaceable without tools. The base structure may be a deck pad on a boat or a covering for a floor, spa, spa cabinet, pool, or any other surface. The deck may comprise EVA or PE foam material, and may comprise one or more layers of sheet material. The retaining cavity may comprise a window and bevels for visibility. A lighting element may be held in place by forces created when the compressible material of the base structure is compressed by pressing the lighting element into the retaining cavity.

  • Patent number: 10758134
    Abstract: A sensor that is capable of detecting a pulse of a user by using a proximity illumination sensor or a proximity sensor is provided. A proximity sensor (14) that includes a pulse detection function includes a count adjustment circuit (5) that performs adjustment such that a digital output value (ADCOUT1) from an analog-digital conversion circuit (4) changes in accordance with each value of a distance at least in a prescribed range of the distance between a photodiode (2) and a detected object (a finger in the drawing) and a digital filter (6) for detecting a cycle of the digital output value (ADCOUT1) from the analog-digital conversion circuit (4).

  • Patent number: 10762624
    Abstract: A piece of medical information, e.g., a medical image of tissue, may be received for processing and analysis on a computing device or system. A region of the medical image may be analyzed to determine a presence of one or more contours in the region. One or more properties of the one or more contours may be extracted, where the one or more properties are inputted into a first algorithm to determine an indication of cancer for the region. The indication of cancer may be inputted into a second algorithm to generate a cancer score for the region.

  • Patent number: 10750958
    Abstract: A physiological monitoring device controls an optical signal acquisition system within a number of discrete operating states, each providing values for controllable parameters such as illumination intensity for a light source and the gain for an optical detector. Using this technique, a small number of operating states may be defined, such as operating states that are known to work well within expected use scenarios. This approach advantageously facilitates optimal or near optimal operation across a range of most likely use cases while avoiding complex or continuous optimization problems. The list of operating states may further be prioritized so that a best operating state can be selected based on, e.g., signal quality or environmental conditions.

  • Patent number: 10750983
    Abstract: Disclosed herein is a physiological measurement system that can automatically adjust the number of wavelengths used based on the quality of a sensor signal that is reflective of an optical radiation detected at a sensor after tissue attenuation. The signal quality is examined to determine if it is sufficient to support the use of a full set of wavelengths. If it is determined to be insufficient to support the full set, a reduced number of wavelengths is used.

  • Patent number: 10743818
    Abstract: Reducing noise in a signal is provided. A first filter includes a selectively definable passband for filtering a first signal used in determining at least one patient parameter. A characteristic analyzer detects a characteristic of a second signal and generates a variability measurement value using a series of data values within the second signal over a previously occurring window of time. A filter controller coupled to the characteristic analyzer uses the variability measurement value to define a characteristic of the passband for the first filter and selectively tunes the passband of the first filter according to the defined characteristic. Related apparatus, systems, techniques, and articles are also described.

  • Patent number: 10729362
    Abstract: Because reprocessing or refurbishing of physiological sensors reuses large portions of an existing sensor, the material costs for refurbishing sensors is significantly lower than the material costs for making an entirely new sensor. Typically, existing reprocessors replace only the adhesive portion of an adhesive physiological sensor and reuse the sensing components. However, re-using the sensing components can reduce the reliability of the refurbished sensor and/or reduce the number of sensors eligible for refurbishing due to out-of-specification sensor components. It is therefore desirable to provide a process for refurbishing physiological sensors that replaces the sensing components of the sensor. While sensing components are replaced, generally, sensor cable and/or patient monitor attachments are retained, resulting in cost savings over producing new sensors.
