The sleeve and shaft are aligned with a slot and a pin to prevent rotation of the shaft within the sleeve. The baton also includes a shock absorbing assembly positioned on the shaft.

Abstract: A modular law enforcement baton having at least two useful functions disposed at a first end and a second end is described. The police baton comprises a unit comprising a handle and an elongated member connected to the handle. A first portion of the unit comprises a battery module and a battery for completing a first useful task. A second portion of the unit comprises a module for completing a second useful task. Useful tasks include but are not limited to providing light, providing pepper spray, optical scanning, measuring vehicular speed, measuring human blood alcohol levels, etc. The police baton may further comprises at least one of an accelerometer, a force gauge, and a strain gauge positioned within the unit and capable of measuring at least one of the acceleration, the force, and the strain to which a police baton is typically subject. The police baton may further comprise an automated processor, memory, persistent storage, a radio.

Abstract: A fight analysis system to objectively determine the quality and quantity of strikes in a fight. In one exemplary embodiment, one fighter wears a receiving module having a plurality of passive RFID tags at different locations that are read by a striking module (e.g., a knife) when the striking module lands on, or comes in proximity to, the receiving module, to provide the location of a strike. Force sensors in the striking module enable determination of the type and force of a landed strike. A graphical user interface module displays information gathered by the fight analysis system.

Abstract: A baton includes an elongate housing with a first compartment and a second compartment. A power source is located in the first compartment. An interchangeable operative component is located in the second compartment and may be removable/replaceable. The interchangeable operative component may be a training module, a light source, a laser generator, a sound generator, an incapacitation waveform generator, and combinations thereof.

Abstract: A security device and system includes a substantially flat body with an opening formed therein. The opening has a predetermined length and a predetermined height such that an elongated end of a key passes through the opening and a head end of the key does not pass through the opening. A user gripping the security device may then use the elongated end of the key extending outward therefrom as a weapon or tool for self-defense.

Abstract: A side ring baton is disclosed. The side ring baton is comprised of an elongated cylindrical shaft with an anterior end and a posterior end, and a side ring having a circular interior, tangentially connected to the elongated shaft near the anterior end of the elongated shaft. The side ring is fixed stationary in a horizontal plane with the elongated shaft. The side ring baton also has a finger fulcrum between the shaft and posterior side of the side ring for rotational acceleration. The side ring baton further has a mini light attached to the finger fulcrum of the baton for providing light in the night.

Abstract: Baton (1) includes two handles (14, 16), a first body portion (2) and a second body portion (3) which telescopically slides between a retracted and an expanded configuration. Retaining device (6) holds body portion (3) within body portion (2) when baton (1) is in the retracted configuration. First handle (14) is oriented perpendicular to body portion (2) and is mounted on collar (15) for rotation around body portion (2). Second handle (16) is moveable between a first position wherein handle (16) is aligned with the outer end of body portion (3), and a second position wherein handle (16) is spaced from the outer end of body portion (3) and is arranged perpendicular to second body portion (3). Baton (1) is telescopically expanded by pulling handle (16) away from body portion (2) until the pulling force exceeds the retaining force provided by retaining device (6).

Abstract: A truncheon comprises an outer casing member including a smaller engagement portion on an outer end, at least two holes on engagement portion, and at least two detents movable in holes; a flexible sleeve sliding on engagement portion and including an inner peripheral limiting shoulder, an elastic member confined by sleeve and engagement portion being biased against the limiting shoulder, and a peripheral stop on outer casing member engaged with an inner end of sleeve in a storage position of truncheon; a handle extended from outer casing member; and a sliding rod in outer casing member. In use, after rod is unlocked pull rod outwardly from outer casing member until detents lock in first indented portion of rod. In storage, press sleeve laterally and inwardly until sleeve engages stop, thus permitting detents to clear from first indented portion prior to retracting rod into outer casing member until detents lock in a second indented portion or rod. This effects a smooth activation of detents.

Abstract: A baton structure is provided. The baton structure includes a knocking cylinder and a hollow connecting tube integrally extending from a surface of the knocking cylinder. A handle is pivotably mounted to the hollow connecting tube so that the handle is foldable to reduce the storage volume of the baton structure.

Abstract: A hand-held personal defense/police baton comprising an elongated, telescoping main cylinder having an extendable first end and a second end comprising a rounded, shatter-proof light that is secondarily useable for jabbing maneuvers. Proximate the second end is a mushroom-shaped side handle that extends transverse to the main cylinder. The side handle houses a pressurized chemical spray canister operated by a push button and having safety features to prevent accidental discharge. The side handle also has a dome-shaped locking top that conceals the push button and canister, and that may be properly used in striking maneuvers. Multiple embodiments of the closure and lock are disclosed.
