  • Publication number: 20160151216
    Abstract: Multi-layer cushion supports are described which may generally comprise a first support having a first contact surface for contacting a portion of a body and a second surface opposite to the first surface, the first support defining a central chamber and a peripheral chamber surrounding the central chamber, wherein the first support is filled with a first gas or liquid and a second support attached to the first support along the first contact surface. The second support may be filled with a second gas or liquid which is relatively more viscous than the first gas or liquid. In particular, the first support may be filled with a volume of air and the second support may be filled with oil which is less than the volume of air.

  • Patent number: 8887732
    Abstract: Method and devices for the prevention and treatment of pressure ulcers are described in which a portable support assembly may be worn by a bed-stricken individual around particular regions of the body where pressure ulcers tend to form. The portable support assembly may generally include one or more individual fluid filled pods which are enclosed entirely within an inner fluid pad localized along a central portion. Both the one or more pods and inner fluid pad are then enclosed entirely by another layer of fluid within an outer fluid pad which extends over the entire assembly. Each of the fluid layers may be secured to an outer shell which is relatively stiffer than the fluid layers and may restrict or limit the expansion or movement of the fluid pods and/or fluid pads.

  • Publication number: 20140249382
    Abstract: A motion detection system for detecting movement and/or breathing from a subject, e.g., for preventing SIDS, can incorporate a sensor in communication with a fluid-filled chamber while optionally combining audio and/or video monitoring systems. The sensor module may have a housing which can be attached, e.g., to an article of clothing worn by the subject. The sensor may be entirely enclosed within the housing which may also be filled with a vibrationally transmissive medium which transmits movements from the subject such that these signals impinge upon the sensor which captures these signals (or the absence of these signals) for processing and possibly alerting a parent or caretaker.

  • Patent number: 8813753
    Abstract: Systems and methods for detecting an obstructive sleep apnea event are disclosed herein. The systems and methods may use an electrical output generating ionic polymer metal composite sensor attached to a region in an airway passage in an oral cavity. The electrical output may be wirelessly transmitted as a signal for indication of an obstructive sleep apnea event. The signal may be further analyzed for treatment of the obstructive sleep apnea event.

  • Patent number: 8555891
    Abstract: Techniques for operating a subcutaneous implant device are disclosed. The implant device can be formed of a non-magnetic material that is compatible with diagnostics such as magnetic resonance imaging (MRI) and can include a rotor element that rotates under the influence of an external magnetic field. The implant device includes a tension relief mechanism for relieving excessive force applied between the implant device and a portion of a patient's tongue. A non-implanted device can include a stator and drive circuitry for generating the external magnetic field. The non-implanted device can receive a user command and can vary the external magnetic field based on the command. When activated by the magnetic field, the implant device can change its operating state to interact with the patient's body.

  • Publication number: 20130161957
    Abstract: Energy harvesting systems are described in which electroactive materials, such as dielectric elastomers, may be utilized to absorb the shocks, bumps, and vibrations from the road or path to generate energy which is captured and stored for use in the vehicle to provide additional power for any number of uses. Other devices and systems. such as household appliances which dissipate vibrational energy, may also incorporate any number of the dielectric elastomer generators.

  • Patent number: 8430920
    Abstract: A device and methods for treating tissue via laser energy to induce tissue reduction and/or necrosis are described herein. Laser energy may be applied to a tissue region via an optical fiber advanced through a lumen of at least one needle. Fluid may also be infused or injected into the tissue region through at least one needle. Tissue reduction and/or necrosis of a target tissue region in turn reduces the appearance of droopy, baggy and/or wrinkled skin.
