Detecting Body Movement Attending Breathing Patents (Class 600/534)
  • Patent number: 10657950
    Abstract: A headphone has a driver, an internal microphone, an accelerometer, and an external microphone. An audio processor analyzes signals to detect wind noise. Gain of lower frequencies is reduced relative to higher frequencies, in a first filter that is operating on an audio signal from the external microphone in a feedforward path, responsive to detecting increased wind noise. A second filter in an audio signal feedback path may be adjusted to compensate for the gain change in the first filter that may mitigate occlusion effect. Outputs of the feedforward path in the feedback path are combined to produce an audio signal for the driver. The driver produces sound in the aural canal that has transparency with reduced wind noise, relative to sound external to the headphone. Other aspects are also described and claimed.

The force sensing array includes a plurality of force sensors. The force sensors are defined where a row conductor and a column conductor approach each other on opposite sides of a force sensing material, such as a piezoresistive material. In order to reduce electrical cross talk between the plurality of sensors, a semiconductive material is included adjacent the force sensing material to create a PN junction with the force sensing material. This PN junction acts as a diode, limiting current flow to essentially one direction, which, in turn, reduces cross talk between the multiple sensors.

  • Patent number: 9610457
    Abstract: Implantable devices and/or sensors can be wirelessly powered by controlling and propagating electromagnetic waves in a patient's tissue. Such implantable devices/sensors can be implanted at target locations in a patient, to stimulate areas such as the heart, brain, spinal cord, or muscle tissue, and/or to sense biological, physiological, chemical attributes of the blood, tissue, and other patient parameters. The propagating electromagnetic waves can be generated with sub-wavelength structures configured to manipulate evanescent fields outside of tissue to generate the propagating waves inside the tissue. Methods of use are also described.

  • Patent number: 9492105
    Abstract: The present invention is related to a compact, portable, user-friendly sleep disorder diagnosis and screening device. The present invention is further related to a single-ended respiratory inductance plethysmography belt used to monitor certain parameters of a subject's respiration while at the same time serving to position and mechanically stabilize a compact data acquisition system about a subject's thorax or abdomen. In one application of the present invention to screen for sleep disorders, the single-ended respiratory inductance plethysmography belt is worn by the subject and a compact data acquisition unit is attached to the belt to which appropriate additional sensors and components such as a pulse oximeter and a nasal cannula are connected. Data is then collected using the belt, compact data acquisition unit, and sensors and is used to determine whether the subject has, or is at risk of having, a sleep disorder.

  • Patent number: 9462978
    Abstract: A sensing device comprises a substrate material layer and a plurality of sensors provided on the substrate material layer. The plurality of sensors is electrically connected to form a loop. The loop has two output ends. There is a loop output value between the two output ends. The loop output value varies when the sensors are subjected to an external force. Each sensor has one induction value. The induction value of each sensor is different from each other. A total induction value of any one or more sensors is different from a total induction value of the other one or more sensors.

  • Patent number: 9333351
    Abstract: Methods and systems are provided to deliver a neural stimulation therapy to treat apnea episodes. The methods and systems detect a respiratory pattern of a patient and identify a type associated with the respiratory pattern. A sleep stage is detected that the patient is experiencing and the method and system identify when the sleep stage warrants therapy. When the respiratory pattern corresponds to an apnea episode (AE) and the sleep stage warrants therapy, the methods and systems deliver an apnea episode terminating neuro-stimulation (AET-NS) therapy configured to terminate the AE. A type of AE therapy that is delivered may be based on the sleep stage that was detected. The methods and systems may determine whether the AET-NS therapy successfully terminated the AE, and, if not, adjust the AET-NS therapy and deliver a new AET-NS therapy.

    Abstract: An adjustable bed includes a stationary frame, a first head deck mattress support member supported by the frame, a second seat deck mattress support member supported by the frame and pivotally coupled to the head deck mattress support member, a sensor assembly adapted to detect a sound associated with human snoring, and a motorized drive assembly operatively coupled to the sensor assembly and to the first mattress support member. The adjustable bed may be such that detection of the snoring sound actuates the motorized drive assembly thereby causing relative movement of the first mattress support member with respect to the second mattress support member. The sensor assembly may further be adapted to recognize a sound associated with snoring of a particular person and actuation of the motorized drive assembly may move the first mattress support member between an inclined position and a horizontal flat position.
