Abstract: A grasp-activated power switch is integrated within a handle for a hand-held power tool. The switch has an outer shell defining an inner channel with a first and second pin extending therein. The tool body has a first and second conductor. A motor within the tool body is electrically connected to one of the first or second conductors and to an internal battery. The internal battery is connected to the other of the first or second conductors. On its surface the outer shell has actuating and non-actuating areas. A manual grasping force when applied to the actuating area connects the first and second pins with the first and second conductors to complete an electrical circuit. The closure energizes the tool motor. With each grasp, the switch toggles power to the motor off or on, and when on, the motor transmits power through the inner channel.

Abstract: A grasp-activated power switch is integrated within a handle for a hand-held power tool. The switch has an inner channel having an outer conductive layer, and a flexible outer shell having an inner conductive layer separated from the outer conductive layer by an air gap. On its surface the outer shell has actuating and non-actuating areas. A manual grasping force when applied to the actuating area flexes the inner conductive layer across the gap and electrically couples the two layers. The closure energizes an RF transmitter, which sends a pulse to a complementary receiver. With each pulse, the receiver toggles power to a motor off or on, and when on, the motor transmits power through the inner channel. When operating the tool, an operator may grasp the non-actuating area to avoid powering the tool off or on. The inner conductive layer may consist of conductive segments separated by a resilient insulator that maintains the switch open in the absence of a grasping force.

Abstract: The present device is a wrist and forearm protector intended to reduce or eliminate contact between a user's skin and potentially hazardous liquids such as blood. This protector can be worn over a latex glove, thus preventing the glove from slipping down. In an embodiment, the wrist and forearm protector can comprise a tear-away strip allowing the protector to be removed without pulling it over the user's skin and risking contamination from the exterior of the protector. Other embodiments can comprise textured surfaces for increasing friction between the exterior of the protector and skin or absorbent pads, which can be used to wipe up excess liquids.
