A displacement resistant finger sensor and method of use for reducing motion-related artifacts by mechanical isolation from external forces by providing a resilient sensor body having a digit entrance, a sensor holder, and a fenestrated region between the digit entrance and the sensor holder. The sensor holder maintains sensing elements relative to a user's finger, with said sensing elements being in communication with a monitoring device via a lead wire. The lead wire may extend at a lateral edge of the sensor body. A force to the lead wire may be applied so as to distort the fenestrated region without substantially disturbing the sensing elements relative to the finger surface.

Abstract: A combination guitar arm rest and leg rest for attachment to a portion of a body of a guitar and holding the guitar away from a guitar player's arm or elbow and above the player's leg. The combination includes an arm rest pad and a leg rest pad. The arm rest pad and the leg rest pad are pivotally attached to a tang. The tang is pivotally mounted on a yoke. The yoke is pivotally attached to one end of a pair of struts. An opposite end of the struts is pivotally mounted on a suction cup pivot pin. Opposite ends of the pivot pin are attached to a pair of suction cups. The suction cups are adapted for releasable attachment to the body of the guitar. The tang, the yoke and the struts allow the arm rest pad and the leg rest pad to be pivoted in an “XY” vertical plane, a “YZ” vertical plane and a “XZ” horizontal plane for infinite adjustments by the guitar player.

Abstract: A manifold assembly and method of making the same is disclosed. The manifold assembly is preferably made of a polymer. A mold is used to make the manifold portion of the manifold assembly such that small diameter passageways and valve seats are formed enabling use of small solenoids. Since pressure is applied to small diameter plunger seals (valves) driven by solenoid plungers, small solenoids may be used because the force on the solenoid plungers is correspondingly low. The manifold assembly is comprised of a manifold portion and a plug portion. The manifold portion, as disclosed, has an inlet port for the supply of air pressure. An inlet housing in which an inlet solenoid is housed, a supply port for supplying air to or exhausting air from a reservoir, and an exhaust housing in which an exhaust solenoid is housed are connected to a chamber. The chamber which interconnects the housings and supply port is enclosed by the plug portion which is ultrasonically welded to the manifold portion.
