  • Patent number: 10234330
    Abstract: Described herein are systems and methods for mounting optical sensors in physiological monitoring devices worn by a user to sense, measure, and/or display physiological information. Optical sensors may be mounted in the rear face of the device, emit light proximate a targeted area of a user's body, and detect light reflected from the targeted area. The optical sensor may be mounted in a housing or caseback such that at least a portion of the optical sensor protrudes a distance from at least a portion of the housing. The protrusion distance may be adjustable such that a user may achieve a customized fit of the wearable device. Adjustment of the protrusion distance may also result in a customized level of contact and/or pressure between the optical sensor and the targeted area which may, in turn, result in more reliable and accurate sensing of physiological information.

    Abstract: Diffuse optical flow (DOF) sensors can be used to assess deep tissue flow. DOF sensors positioned on a foot can provide fluctuating light intensity data to an analyzer, which can then determine absolute and/or relative blood flow. The determined absolute and/or relative blood flow can be signaled to an operator, for example a surgeon for intra-operative use. DOF sensors may be utilized to assess pedal revascularization, for example to guide interventional procedures and to evaluate their efficacy. A support structure can carry a plurality of DOF sensors, such that when the support structure is placed onto a patient's foot, the DOF sensors are disposed adjacent different locations on the foot. The different locations may correspond to different topographical regions of the foot, for example different pedal angiosomes.

  • Patent number: 10006810
    Abstract: A semiconductor sensor system, in particular a bolometer, includes a substrate, an electrode supported by the substrate, an absorber spaced apart from the substrate, a voltage source, and a current source. The electrode can include a mirror, or the system may include a mirror separate from the electrode. Radiation absorption efficiency of the absorber is based on a minimum gap distance between the absorber and mirror. The current source applies a DC current across the absorber structure to produce a signal indicative of radiation absorbed by the absorber structure. The voltage source powers the electrode to produce a modulated electrostatic field acting on the absorber to modulate the minimum gap distance. The electrostatic field includes a DC component to adjust the absorption efficiency, and an AC component that cyclically drives the absorber to negatively interfere with noise in the signal.

  • Patent number: 9999711
    Abstract: Disclosed herein are systems and methods for providing reduced or negative pressure, and more particularly cyclical reduced pressure, to treat a wound. The system can include a wound dressing, a fluid collection container, a suction source, filters, and conduits. In addition, the system can include a control device and sensors. The sensors may be configured to monitor certain physiological conditions of a patient such as temperature, pressure, blood flow, blood oxygen saturation, pulse, cardiac cycle, and the like. Application of cyclical reduced pressure between two or more values below atmospheric pressure may be synchronized with the physiological conditions monitored by the sensors. Certain embodiments of the system utilize an air reservoir and one or more valves and pressure sensors or gauges to allow for rapid cycling of the level of reduced pressure within the wound dressing between two or more reduced pressure values.

  • Patent number: 9986353
    Abstract: An electronic device may be coupled to an accessory such as a pair of earphones. The earphones may have ear presence sensor structures that determine whether or not the ears of a user are present in the vicinity of the earphones. The earphones may contain first and second speakers. When both the first and second speakers are located in the ears of the user, the electronic device may perform functions such as playing audio content. When one of the speakers has been removed from the ears of the user while the other of the speakers remains in the ears of the user, the electronic device can take actions such as pausing the playback of audio content, switching from stereo to monophonic playback, or stopping the playback of content. Suitable actions such as increasing audio drive strength may be taken when both speakers have been removed from the ears.

  • Patent number: 9946931
    Abstract: An approach for land cover classification, seasonal and yearly change detection and monitoring, and identification of changes in man-made features may use a clustering of sparse approximations (CoSA) on sparse representations in learned dictionaries. A Hebbian learning rule may be used to build multispectral or hyperspectral, multiresolution dictionaries that are adapted to regional satellite image data. Sparse image representations of pixel patches over the learned dictionaries may be used to perform unsupervised k-means clustering into land cover categories. The clustering process behaves as a classifier in detecting real variability. This approach may combine spectral and spatial textural characteristics to detect geologic, vegetative, hydrologic, and man-made features, as well as changes in these features over time.
