A pet accessory device comprising: a bistable spring having a first equilibrium position and a second equilibrium position, where the bistable spring is in an extended state and in a coiled state at the first equilibrium position; and a hairbrush coupled to the bistable spring, where the hairbrush is positioned to brush hair when the bistable spring is in an extended state and when the bistable spring is in a coiled state.

Methods and systems for fabricating and operating a bi-stable solenoid actuator are described. The system may include permanent magnets that are arranged in a circle. The permanent magnets may provide sufficient force to maintain a differential in a locked state when electric power is not applied to a coil that operates as an electro-magnet.

A de-cocking mechanism for a trigger device is described. The de-cocking mechanism comprises an articulated latch and a bi-stable camming detent mechanism. The articulated latch comprises a string hook and a latch arm. The bi-stable camming detent mechanism is movable between a ready position and a primed position. When the bi-stable camming detent mechanism is in the ready position, a first cocking motion applied to the string hook engages the articulated latch and the latch arm moves the bi-stable camming detent mechanism to the primed position. When the bi-stable camming detent mechanism is in the primed position, a second cocking motion applied to the string hook causes the bi-stable camming detent mechanism to disengage the articulated latch and return to the ready position.
