Novel tools and techniques are provided for the detection and differentiation of activities and/or conditions based on measured bio-signals.

An electrode lead comprises an electrically insulative cuff body and at least three axially aligned electrode contacts circumferentially disposed along the inner surface of the cuff body when in the furled state. The electrode contacts may be circumferentially disposed around a nerve, and an electrical pulse train may be delivered to the electrode contacts thereby stimulating the nerve to treat obstructive sleep apnea. The electrical pulse train may be one that pre-conditions peripherally located nerve fascicles to not be stimulated, while stimulating centrally located nerve fascicles. A feedback mechanism can be used to titrate electrode contacts and electrical pulse train to the patient. A sensor that is affixed to the case of a neurostimulator can be used to measure physiological artifacts of respiration, and a motion detector can be used to sense tapping of the neurostimulator to toggle the neurostimulator between an ON position and an OFF position.

A wireless implantable neuromuscular stimulator includes an antenna for producing an induced current in response to being disposed in an electromagnetic field. The antenna includes a substrate having an upper surface and a lower surface. An upper coil including a plurality of coil turns is disposed on the upper surface of the substrate. A lower coil including a plurality of coil turns is disposed on the lower surface of the substrate. The upper and lower coils are electrically connected to each other in parallel. The parallel connection can be facilitated by a plurality of connectors that extend through the substrate and electrically connect the upper coil to the lower coil. In one example configuration, connectors connect each coil turn of the upper coil to a corresponding turn of the lower coil.

A reflective cable system for a geophysical survey system includes a reflective cable that includes a conductive wire surrounded by an electrically insulating sheath and an exterior surface. The reflective cable includes reflective material that is on or visible through the exterior surface and that is configured to reflect a complete spectrum of light provided by a light source back to the light source. The reflective cable system also includes a connector electrically coupled to at least one end of the reflective cable and configured to couple to a geophysical survey system. The reflective cable may be used to locate the reflective cable in a physical environment and used to determine a position of the reflective cable using lidar or photogrammetry for generating geophysical survey models.

The present invention relates to a system (1; 1A) for use in connection with mechanical ventilation of a patient (3), provided by a ventilator (5). The system comprises a sensor arrangement (7; 7A; 7B) configured to register at least one signal (S.sub.LP; S.sub.LP(TA), S.sub.LP(CT); S.sub.e1-5; S.sub.e11-12), herein referred to as LP signal, related to muscular activity of at least one muscle (17, 19) in the laryngopharyngeal region (9) of said patient (3). Furthermore, the system comprises at least one control unit (11; 11A, 11B) configured to control the operation of said ventilator (5) based on said at least one LP signal, and/or to cause display of information related to said at least one LP signal on a display unit (13A, 13B) for monitoring said patient (3) and/or the operation of the ventilator (5).
