The control board may include sensors such as barometric, proximity, acoustic, infrared and the like. The initiation of the payload release can be as a result of inputs from such sensors in addition to low voltage or particular energy programming which may occur prior to launch. The launcher may also include a range finding means that can detect a distance to target.

Abstract: An impacting apparatus comprises a motor to actuate a spring striker assembly that includes a gas spring piston that is coupled to a striker. After a sufficient movement of the piston, the piston commences movement and accelerates the spring striker assembly to impact a substrate or object. The motor is coupled to the spring striker assembly through an interrupted drive mechanism such as a chain and sprockets configuration for providing for continuous impacting/driving. The drive mechanism alternatively actuates the piston of the spring striker assembly and decouples from the spring striker assembly to allow pressure or other force to act on the spring piston. The gas spring is replaceable and becomes slightly energized when installed in the apparatus by a gas spring preload means.

Abstract: An orthopedic rotary tool may include a drive system including a first rotary component and a second rotary component, an energy storage element, an actuator system including a first actuator element disposed on the first rotary component and a second actuator element disposed on the second rotary component, a coupling mechanism, and an output element.

During operation, the energy storage element may accumulate rotational energy via the drive system and relative rotation between the first rotary component and the second rotary component may cause interactions between the first actuator element and the second actuator element. The interactions may transition the coupling mechanism between the coupled states and the decoupled states. When the coupling mechanism is in the coupled states, the energy storage element may be configured to deliver a torque impulse to the output element.

Abstract: A nonlethal projectile includes a debilitating material for immobilizing a target. The projectile is capable of self-separating or otherwise opening after launch by a launcher to release the debilitating material prior to impact with a target. The launcher is capable of initiating separation of the projectile. Opening may also be accomplished by a control circuit with a radio-frequency identification (RFID), where an RFID tag in the projectile causes the projectile to open at a user-specified distance from the launcher or by the force of launch on the projectile. A magazine may holds a plurality of projectiles and the various projectiles of the magazine may be configured to open at different distances and/or times after launch. The launcher may include a trigger and/or a safety switch to prevent the projectile from becoming armed until a certain parameter is met. The debilitating material may also be released through pores in the projectile.

Abstract: An electrically driven orthopedic impactor may include an adapter for interfacing between the orthopedic impactor and a surgical implement. The adapter may have a first surface that transmits a forward impact energy and a second surface that transmits a reverse impact energy.

The adapter may connect to the orthopedic impactor via a pushing motion and may disconnect from the orthopedic impactor via a reciprocal sleeve. A sensor can communicate a spatial orientation of the adapter with respect to at least one reference point that is not located on the adapter or the orthopedic impactor. A communication device may transmit information to the orthopedic impactor related to frequency or impact energy settings based on a type of surgical implement attached to the adapter.

Abstract: A motor-driven orthopedic impacting tool is provided for orthopedic impacting in the hips, knees, shoulders and the like. The tool is capable of holding a broach, chisel, or other end effector, which when gently tapped in a cavity with controlled percussive impacts, can expand the size or volume of an opening of the cavity or facilitate removal of the broach, implant, or other surgical implement from the opening. A stored-energy drive mechanism stores potential energy and then releases it to launch a launched mass or striker to communicate a striking force to an adapter in either a forward or reverse direction. The tool may further include a combination anvil and adapter and an energy adjustment mechanism to adjust the striking force the launched mass delivers to the adapter in accordance with a patient profile.
