摘要： An apparatus for mixing bone cement for use in orthopedic surgeries includes a mixing region and an agitator for mixing the cement ingredients. The apparatus can be operated or acted on by a power tool for the mixing of the bone cement. The agitator may act as a generator to charge embedded electronics of the apparatus such as with a magnet in the agitator that interacts with a wire coil outside of the agitator. A timer of the apparatus may be started by a sensor of the apparatus, in response to a mechanical torque value, or by a magnetic sensor that can sense a start state of the apparatus. When the timer is complete, a cue by the apparatus signals to the user that the mixed cement is ready and able to be applied.

摘要： A rotary impactor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil. The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to impact the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary impactor. High frequency linear impacts by the impactor obviate the need for a surgeon to provide an external push force on the impactor in order to perform a successful surgical operation.

摘要： A lethal projectile for immobilizing a target is capable of self-separating or otherwise opening after launch by a launcher and may release a payload prior to impact with a target. Opening may caused after an energy storage means of the projectile is charged beyond a threshold energy level. Charging of the energy storage means may be accomplished through dynamic induction when the projectile moves through a stationary magnetic field generated by a magnet of the launcher prior to launch, A control circuit can increase or decrease the magnetic field strength of the magnetic field in order to control the distance at which the projectile releases its payload, A rangefinder may provide distance information to the control circuit for charging the energy storage means to a specific energy level associated with the distance to a target.

摘要： A rotary torque releaseor for orthopedic surgery includes an output anvil and a hammer that is capable of imparting linear and rotary force on the anvil, The anvil may be moveable on a leadscrew element to alternately generate energy in an energy storage means and to move along the leadscrew element to torque release the anvil. A viscoelastic mechanism or a dampening mechanism is used to reduce the reflected force and or torque during operation of the rotary torque releaseor. High frequency axial movements by the torque releaseor obviate the need for a surgeon to provide an external push force on the torque releaseor in order to perform a successful surgical operation.

摘要： 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 hold 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.
