Abstract: A fixed pin bow sight is comprised of a bow sight having an attachment portion, a sight pin mounting portion and a sight pin having a plurality of sight tips on said sight pin. Each of the sight tips are predisposed on the sight pin and spaced to provide accurate targeting of an arrow shot from a bow having a particular shooting speed. The spacing between sight tips is defined by the desired targeting distances from the bow. For example, the uppermost sight tip may be configured for a target that is twenty yards away with subsequent sight tips provided for ten yard increments (e.g., 30, 40, 50 and 60 yards). The sight tips are configured to be vertically aligned relative to the ground when firing the bow so that as the distance from target is increased the appropriate sight tip moves from top to bottom of the sight pin.

Abstract: An inhalation-activated inhalator having a primary inhalation passage and a secondary inhalation passage disposed in communication with the primary inhalation passage and a source of medicament. The primary inhalation passage has airflow inhibiting mechanism connected to a blocking plate positioned to selectively block fluid flow in the secondary inhalation passage. As the user's inhalation reaches a defined rate, the flow inhibiting mechanism restricts flow through the primary inhalation passage and moves the blocking plate to enable airflow through the secondary passage. Thus, as the user achieves a desired inhalation rate, the medicament is provided through the secondary inhalation passage, thereby optimizing the delivery of medicament to the lungs.

Abstract: An arrow rest for an archery bow includes a mounting bracket for mounting to the riser of a bow, a shaft rotatably attached to the mounting bracket, a pair of arms configured for supporting the shaft of an arrow attached to the shaft, and a support member attached to said shaft for rotation therewith. A first magnet is attached to the mounting bracket and as second magnet is attached to the support member. The magnets are oriented to be attracted to one another to form a magnetic spring between the mounting bracket and the support member. The magnet spring holds the pair of arms in a first position for launching of an arrow from the bow but allow pivotal rotation of the arms upon launching of the arrow so that the arrow rest creates minimal drag on the shaft of the shaft of the arrow.

A housing may also be included to provide better control over light refraction and to protect the optical sensor.

Abstract: A system and method for manufacturing a mid-grip high-powered pistol by modifying an existing rifle receiver, wherein a portion of the original trigger is removed, a new trigger is added in a position forward of the partially removed original trigger, and the new trigger is coupled to the remaining portion of the original trigger via an extension, wherein a recoil lug is added to the rifle receiver to handle the recoil, a plurality of different length barrels can be coupled to the new pistol, and a pivot pin diameter and location of a forearm lug prevent creation of an illegal rifle.

Abstract: An optical pressure monitoring system includes a tube from an infusion set and an optical signal sensor disposed to detect changes in the diameter of the tube and thereby determine pressure changes within the tube. By selecting the position of the tube relative to the optical signal emitter and optical signal receiver, the optical signal sensor can both detect pressure changes and provide an integrity check for both the functioning of the optical signal sensor and the placement of the tube. By modifying the tube to exaggerate changes in tube diameter responsive to pressure changes, the sensitivity of the optical signal sensor can be increased.

Abstract: An improved roller for peristaltic pumps includes a central portion and a plurality of projections extending radially outwardly from the central portion. The projections enable use of a roller having a larger diameter, while ensuring that the tube carrying the solution is effectively pinched off. The larger diameter roller provides a greater moment arm and decreases current draw. The small projections used to accomplish the seal also severely deforms a smaller amount of tubing and thus requires less current draw.
