  • Patent number: 9805699
    Abstract: A guitar arm rest adapted for mounting on a side of a guitar for holding a guitar player's arm in a proper position on the guitar. The guitar arm rest includes an arm rest cup received next to an edge of the side of the guitar. A front of the arm rest cup is adapted for receiving the guitar player's arm thereon. A base plate is hinged to a back of the arm rest cup. The base plate includes one or more suction cups for securing the guitar rest on the side of the guitar. One end of a height adjustment pivot plate is hinged on the base plate. An opposite end of the pivot plate is received in a selected hole in a hole track plate. The hole track plate is attached to a rear of the arm rest cup. The pivot plate is used to adjust the height/angle of the arm rest cup above the side of the guitar.

  • Patent number: 9254087
    Abstract: A device includes a clamp and a sensor. The sensor can be permanently attached to the clamp and tissue by the force exerted by the clamp. The clamp includes a first jaw member and a second jaw member. The first jaw member has a jaw face and the second jaw member has a complementary face. The second jaw member is held in alignment with the first jaw member by a joint. The joint has an elastic member configured to exert a compressive force between the jaw face and the complementary face. The joint is configured to allow movement of the jaw face relative to the complementary face in directions corresponding to pitch, roll, yaw, and heave. The compressive force is distributed over a surface of the jaw face. The sensor is coupled to the jaw face or held in place by the compressive force of the jaw face. The sensor is configured to generate a sensor signal corresponding to a physiological parameter of tissue proximate the jaw face.
