  • Patent number: 10396714
    Abstract: A reconfigurable low-noise amplifier (LNA) is disclosed. The reconfigurable LNA includes amplifier circuitry having a gate terminal coupled to an input terminal, a source terminal coupled to a fixed voltage node, and a drain terminal coupled to an output terminal. The reconfigurable LNA further includes a gamma inverting network (GIN) coupled between the input terminal and the fixed voltage node, wherein the GIN has a first switch configured to disable the GIN during operation at first frequencies within a lower frequency band relative to a higher frequency band and to enable the GIN during operation at second frequencies within the higher frequency band.

  • Publication number: 20190231199
    Abstract: A wireless, patient-worn, physiological sensor configured to, among other things, help manage a patient that is at risk of forming one or more pressure ulcers is disclosed. According to an embodiment, the sensor includes a base having a top surface and a bottom surface. The sensor also includes a substrate layer including conductive tracks and connection pads, a top side, and a bottom side, where the bottom side of the substrate layer is disposed above the top side of the base. Mounted on the substrate layer are a processor, a data storage device, a wireless transceiver, an accelerometer, and a battery. In use, the sensor senses a patient's motion and wirelessly transmits information indicative of the sensed motion to, for example, a patient monitor. The patient monitor receives, stores, and processes the transmitted information.

  • Publication number: 20190231270
    Abstract: An physiological measurement device provides a device body having a base, legs extending from the base and an optical housing disposed at ends of the legs opposite the base. An optical assembly is disposed in the housing. The device body is flexed so as to position the housing over a tissue site. The device body is unflexed so as to attach the housing to the tissue site and position the optical assembly to illuminate the tissue site. The optical assembly is configured to transmit optical radiation into tissue site tissue and receive the optical radiation after attenuation by pulsatile blood flow within the tissue.

  • Publication number: 20190133525
    Abstract: Modular physiological sensors that are physically and/or electrically configured to share a measurement site for the comfort of the patient and/or to ensure proper operation of the sensors without interference from the other sensors. The modular aspect is realized by providing outer housing shapes that generally conform to other physiological sensors; mounting areas for attachment of one sensor to another sensor; providing release liners on the overlapping sensor attachment areas; and/or providing notches, tabs or other mechanical features that provide for the proper placement and interaction of the sensors.

  • Publication number: 20180168491
    Abstract: A regional oximetry sensor has a sensor head attachable to a patient skin surface so as to transmit optical radiation into the skin and receive that optical radiation after attenuation by blood flow within the skin. The sensor includes windows that press into the skin to maximize optical transmission. A stem extending from the sensor head transmits electrical signals between the sensor head and an attached cable. In a peel resistant configuration, the stem is terminated interior to the sensor head and away from a sensor head edge so as to define feet along either side of the stem distal the stem termination. The stem interior termination transforms a peel load on a sensor head adhesive to less challenging tension and shear loads on the sensor head adhesive.

  • Publication number: 20180082767
    Abstract: An automated assembly sensor cable has a generally wide and flat elongated body and a registration feature generally traversing the length of the body so as to identify the relative locations of conductors within the body. This cable configuration facilitates the automated attachment of the cable to an optical sensor circuit and corresponding connector. In various embodiments, the automated assembly sensor cable has a conductor set of insulated wires, a conductive inner jacket generally surrounding the conductor set, an outer jacket generally surrounding the inner jacket and a registration feature disposed along the surface of the outer jacket and a conductive drain line is embedded within the inner jacket. A strength member may be embedded within the inner jacket.
