A hydraulic implement (1) for portable use includes a hydraulic pump (2), a pump housing (10), a hydraulic cylinder (3) with a piston rod (11), a hydraulic tank (4), hydraulic lines, a compensating device, a manually operable hydraulic control valve (8), a rechargeable battery (9) which is accommodated on the implement (1), and two tool halves (16, 17) that are connected to the piston rod (11) via pivoting arms (12, 13). Each tool half (16, 17) has a wall section (20, 21) that extends perpendicularly to the extension of the longitudinal axis of the piston rod (11). When the tool halves are closed, both wall sections (20, 21) together form a flattened end region (24) that runs perpendicularly to the extension of the longitudinal axis of the piston rod (11).

A compact, hand-held anti-assault weapon for repelling attackers while avoiding serious injury to the potential victim. Weapon includes a rigid, metallic, cylindrical body with a concave section to serve as a secure hand grip. End caps seal the opposite ends of the body and define the hollow interior of the body. An electroshock generator is housed within the cylindrical body, and a button, on the exterior of the body, is depressed to actuate the electroshock mechanism, such as a stun gun, or Tazer. An ear on one end cap may be used to break glass, while a series of protrusions on the second end cap may be used to collect a DNA sample from an attacker. The electroshock generator discharges a burst of high intensity electrical beams through the second end cap to shock an attacker.

A pen structure with a glass smasher has the glass smasher mounted at the front end of a pen. When a user holds the pen and presses the front end (i.e., the smashing cone) of the smashing rod of the glass smasher forcibly against a glass obstacle, an impact block will strike the rear section of the smashing rod vigorously such that the smashing cone is instantly driven to smash the glass obstacle. A ballpoint/rollerball refill is detachably provided in the pen and is at least 6 cm long in order to contain enough ink. The overall length of the pen is at least 10 cm so that the pen can be easily held while the user writes or draws with the ballpoint/rollerball tip and while the user applies a force to a glass obstacle through the front end of the smashing rod to smash the glass obstacle.

A power door opener including an actuator having a housing with an electrically powered actuator shaft that can be extended from a closed to an extended position. In one embodiment, a movable push plate is affixed to the actuator shaft and a fixed push plate is fixed in its position with respect to the housing. In the closed position of the actuator shaft, the fixed and movable push plates are aligned to form a combined edge for insertion into the space between a door and door jamb. The actuator shaft extends to move the movable push plate apart from the fixed push plate to spread the space and release the door from the door jamb. Alternatively, a double ended power door opener is located between opposite door jambs and the extending of the actuator shaft forces the door jambs apart to release the door from the door jamb to force open the door.

An extrication rescue tool, configured to open an extrication passage for extricating a victim in a plight, such as a car wreck or a collapsed building. The extrication rescue tool includes a extendable element, which is selectively extendable by a drive along an extension path and configured to forcibly maintain or enlarge an extrication passage to thereby allow extrication of the victim through the extrication passage. When the extendable element is extended an illuminator is oriented along the extension path of the extendable element to identify obstacles in the extension path.

A fireman positioning system includes: a first radio wave emitting device and a second radio wave emitting device, spaced with a predetermined distance and utilized for correspondingly emitting a first frequency modulated signal and a second frequency modulated signal; and a position receiving device, carried or worn by a fireman, and utilized for receiving the first frequency modulating signal and the second frequency modulating signal, and can demodulate the first frequency modulated signal via a first carrier signal so as to obtain a first output signal, and demodulate the second frequency modulated signal via a second carrier signal so as to obtain a second output signal, wherein a phase difference is formed between the first output signal and the second output signal, and the position receiving device can determine a direction angle of the fireman relative to the two radio wave emitting devices via the phase difference.

A safety device with a blade for severing a seatbelt during an emergency. The blade is movably affixed to a blade bar of the safety device, such that the blade can slide along a width of the seatbelt to cut through the seatbelt during an emergency. The safety device includes a housing configured to protect an individual from the blade when the safety device is not in use. The safety device is useful for escaping emergencies, such as automobile collisions and the like.

An impact tool includes a core and a plurality of projections. The core is formed of a first material that has a first specific gravity and each projection is formed of a second material that has a second specific gravity. The plurality of projections is configured on the core such that at least two projections intersect a first hypothetical plane disposed on the first side of the core and at least two projections intersect a second hypothetical plane disposed on the second side of the core and that is opposably facing the first side. Each of the first and second hypothetical planes is disposed a distance from the central lengthwise axis of the core that is greater than the radius of the core and less than the sum of the radius of the core and the length of a projection.
