Abstract: An athletic training device trains athletes to observe the collision between a ball and bat, club, racquet, or the like. The training device may provide a unique event, such as a flashing light, at the moment of the collision. Athletes can be trained to watch the ball, bat, club, racquet or the like, to note the flash of light, thereby focusing the attention of the athlete to “keep their eye on the ball”. The training device of the present invention can provide a unique event that attracts and induces anticipation from the collision point itself. The unique event can be a light flash, multiple light flashes, colored light flashes, or the like.

Abstract: An independently positionable key switch including a key base having a key cap receiving opening and at least one gripping feature operative to facilitate gripping of the key base. An actuatable key cap is arranged in the key receiving opening of the key base. The key cap is actuatable between an unactuated position and an actuated position.

Abstract: A configurable computer input device. A base is operable to generate and detect a radio frequency carrier signal. A plurality independently positionable input members are each operatively positioned in the vicinity of the base and individually operable to modulate the carrier signal responsive to its identity and status.

Abstract: A configurable computer input device. At least one switch is removably attachable to a surface and is in communication with a processor. At least one function is assignable to activation of the switch. The at least one switch may be repositioned distances smaller than a length or width of the at least one switch. Circuitry is in communication with the at least one switch for assigning at least one function to activation of the switch. Circuitry communicates the at least one function to a host computer. Circuitry determines the actuation status of the at least one switch and communicates the actuation status to the host computer.

Abstract: A device for detecting the presence of items made of recyclable materials randomly located and arranged within randomly arranged solid waste having random characteristics. A transmitter produces acoustic energy of at least one predetermined wavelength in a desired direction. The acoustic energy causes the items made of recyclable material present within the randomly arranged solid waste to resonate and thereby produce resonated acoustic energy. A receiver receives the resonated acoustic energy. The receiver generates a signal based upon the resonated acoustic energy. A processor connected at least to the receiver receives the signal from the receiver for analyzing the resonated acoustic energy, for calculating the signal based upon the resonated acoustic energy, and comparing the calculated signature to known signatures of items made of recyclable materials.
