Abstract: The embodiments disclose a stress and strain gauge including at least one stress and strain sensor module configured to sense stresses and strains being applied by an animal biting a rope extending from a protective hand guard, a stress and strain gauge indicator coupled to the at least one stress and strain sensor configured for measuring the sensed stresses and strains as strain levels, a processor coupled to the stress and strain gauge indicator configured to dynamically analyze and compare the strain levels to predetermined threshold strain level measurements to determine a current animal play level that varies incrementally, and an alert module wirelessly coupled to the processor configured to notify a user of the protective hand guard in real-time of the current incremental animal play level.

Abstract: The embodiments disclose an apparatus and method for a pet toy hand guard system including creating a pet toy hand guard, coupling an inside toy hand guard handle to the pet toy hand guard, coupling a pet toy to the pet toy hand guard, using the pet toy hand guard with the pet toy coupled to the pet toy hand guard system encapsulates and protects the hand from a potential/accidental bite, playing with the user's pet with a rope or other pet toy coupled to the hand guard, wherein the user's hand is protected, and gauging the user pet's actions using sensor modules integrated into the pet toy hand guard for determining a level of pet actions from playful to ferocious to violent. The pet toy hand guard handle allows better gripping of pet toy while playing with the pet.

Abstract: A stand-alone power stacker for envelopes and similar type planar articles is provided wherein two end to end arcuately adjustable belt conveyors are adapted to be driven at automatically varying relative speeds depending on load conditions. The machine drive motor is controlled by a sensing means that detects the presence of each envelope that is delivered to the upstream end of the stacker and a time delay control circuit is provided to delay a termination of operation of said motor for a selected time period after said sensing means has completed a sensing operation. The arcuate adjustability of the outer ends of said conveyors permits the upstream one of said conveyors to receive envelopes, etc. from various heights and the downstream one of said conveyors to generate envelope stacks of desired compactness or density.
