Abstract: A powered fastener driver includes a driver blade movable from a top-dead-center (TDC) position to a bottom-dead-center (BDC) position for driving a fastener into a workpiece and a drive unit for providing torque to move the driver blade from the BDC position toward the TDC position. A rotary lifter is engageable with the driver blade and configured to receive torque from the drive unit for returning the driver blade from the BDC position toward the TDC position. The lifter has a body, a drive pin coupled to the body, and a roller positioned on the drive pin. The roller includes an engagement section configured to receive an end portion of a tooth of the driver blade. The lifter includes a means for aligning the engagement section with the end portion of the tooth on the driver blade to facilitate meshing between the end portion and the roller.

Abstract: In one embodiment, a method of alerting a user of a WCD is described. The method includes receiving an alert from the WCD on a remote device associated with the user and in communication with the WCD and transcribing the alert into a message for the user. The method also includes personalizing the message for the user and delivering the message to the user via the remote device.

Abstract: A rescue flotation buoy integrated with a pressurized containment and dispensing device containing a pressurized repellent for sharks. Sodium lauryl sulfate, a well-known shark repellent, is one such material that could be utilized. The repellent material can be dispensed more than one time by the use of a valve connected to the containment and dispensing device. The integration of a rescue flotation buoy and a shark repellent will allow rescue personnel to repel sharks when saving a victim of a shark attack. The purpose is to expose the predator to an immediate high concentration of the appropriate repellent, thereby diverting the predator from its attack. Subsequent applications of the shark repellent can also be performed.

Abstract: A tube is constructed of a heavy duty flexible or rigid plastic or metal and designed for the sealed storage and on demand release of a liquid or dry fish, animal or reptile repellent. Said tube may be a specially fabricated device or a standard fire extinguisher or other common liquid, gas or particle dispenser which can be incorporated into a lifesaving device such as a life guard rescue flotation buoy. The tube's predator specific repellent, for example sodium lauryl sulfate which is a known shark repellent, may be discharged by the user in the event of an attack by the predator. The purpose is to expose the predator to an immediate high concentration of the appropriate repellent thereby diverting the predator from it's attack.

Abstract: To provide a chemical conglomerate which when properly coated or contained can dissolve over very long periods of time in sea water that will discourage shark attack or attacks by other sea creatures that are sensitive to the included chemicals. This chemical can be carried into the sea in many different designs of packaging so that eventually, when called upon, it will dissolve into the sea water and be there in enough quantity to deter sharks that would otherwise attack and cause damage.

Abstract: To provide an enclosed, indoor squirrel feeding compartment which allows indoor viewing of the squirrels while they are feeding without allowing the squirrels access to the indoor area where the feeder is located. A generally transparent box is provided with a squirrel sized passageway which allows the squirrels into to the interior of the boxes' feeding compartment from an access port which is located out of doors. This enclosed passageway can lead through a window opening in the house or some other suitable naturally existing opening in the house's exterior shell.

Abstract: A belt including a pair of opposite layers of sheet material and subdivided into a series of pockets for receiving pellets of shark-repulsive chemical. One of the pellets is untreated so as to dissolve in water relatively quickly, another of the pellets is impregnated with water soluble glue, another of the pellets is coated with the glue while a fourth of the pellets is coated with epoxy for preventing water application to the chemical of the pellet until the pellet is manually broken.

Abstract: A suit for protecting the wearer against shark attack including a plurality of cells formed in the material of the suit which contain a shark-repulsive chemical. The material of which the suit is made includes an inner ply of strong filamentary fabric capable of resisting shark bite and an outer ply of relatively thin, frangible material, with the cells carrying the shark-repulsive chemical being formed between the two plies. Other chemicals alternately may be used in the cells for other purposes, such as for heating purposes on the interaction of two initially separated chemicals in the cells.
