Example clippable multi-tone whistles, as well as systems and methods for manufacturing the same are described. An example clippable multi-tone whistle may comprise: a clip attached to a whistle body. The whistle body comprises a flat surface under the clip; a first opening configured to allow air flow to come into the whistle body; and on the flat surface a second opening configured to allow air flow to come out of the whistle body. The second opening is at least partially blocked by the clip, which controls direction of one or more air flows coming out of the second opening. The whistle part is configured to generate a plurality of different sound tones in accordance with user finger movements around the clip and the second opening. The whistle may further comprise a glass breaker, a length scale, and a bolt action switch, which may function as a fire starter.

The iron entry tool is a multifunctional device for building and vehicle forced entry, flow path blocking, rescue tarp, patient carrier. The entry tool comprises a modular structure that can fit into a wide variety of building openings and vehicle doors that are cut out under traffic collision incidents. The power alarm system of the tool provides critical safety features for rapid egress of firefighters. The canvas of the entry tool can be conveniently rewound to provide a user an efficient means to store and carry the Roses iron entry toll.

An integral rescue accessory for forcible entry and core drill may include hydraulic wall saws, a rotating platform, and a coring claw. Two hydraulic wall saws are symmetry installed on rotating platform. The wall saws cut linearly with the rotation of rotating platform to open a rectangular tunnel on a reinforced concrete wall or floor. After the cutting process, coring process is finished by the wall saws and claw inclinedly mounted to ensure the security of rescue. The whole accessory is installed on a large engineering machine through a hydraulic joint. The present disclosure can transfer general large mechanical equipment into dedicated large mechanical equipment quickly.

A method is for operating an electromechanical or electrohydraulic work appliance or rescue appliance that can be carried and used by an operator, having a movable tool insert, a spreading tool or a lifting tool, a housing, an electric motor, a pump or a mechanical transmission driven by the electric motor, for actuating the tool insert. The appliance has an exchangeable, rechargeable appliance electrical energy source, having a housing in or on the rescue appliance. During operation of the appliance, operating data of the appliance and/or of the energy source are acquired and transferred into a data carrier or data storage device in the electrical energy source. The electrical energy source is removed from the appliance and connected to a charging device. The operating data stored in the data carrier or storage device of the electrical energy source are read by the charging device and transferred to a network.

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.

A portable tool, such as a spreader tool, cutting tool or combination spreading/cutting tool is for mobile use. The tool has an electric motor, a rechargeable battery received on the tool, a mechanically or hydraulically driven, displaceable piston rod for performing spreading and/or cutting and/or lifting or pressing. An electronic control and regulation unit controls/regulates the electric motor, such as a brushless DC motor. The electronic control and regulation unit specifies a first operating mode in which the electric motor is operated at a first frequency, and a second operating mode in which the electric motor is operated at a second frequency. The operating mode is switchable by an operator of the tool using a manually operable switch between the first and the second operating modes. The rotational speed of a three-phase current electric motor is higher at the second frequency than at the first frequency.

A portable, battery-powered hydraulic unit for hydraulic rescue tools, in particular for spreading or cutting tools, as well as a rescue tool equipped therewith, are disclosed. The hydraulic unit includes at least one hydraulic pump, a hydraulic tank, a compensation device for hydraulic fluid, a manually operated hydraulic control valve, an electromechanical interface for on-demand coupling and decoupling of at least one battery pack, a mechanical-hydraulic interface for connecting a hydraulic tool, and an electric motor operable by the electrical energy of the battery pack for driving the hydraulic pump. The electric motor is formed by a disc-shaped motor whose axial length extending in parallel to the longitudinal axis of its output shaft is shorter than its outer diameter.

A sheath attaches to MOLLE webbing using one large hook that secures underneath the top of MOLLE webbing and two or more hooks that attach over the bottom of MOLLE webbing.

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.
