Methods and systems for monitoring blockages of emergency escape routes and emergency exits of a building include capturing a plurality of images which may correspond to an emergency escape route and/or an emergency exit of a building. The plurality of images may be analyzed to determine when a stationary object is present and at least partially blocking the emergency escape route and/or the emergency exit. If a blockage is detected, a user may be notified of the blockage.

A multi-purpose illumination, self-defense and glass-breaking tool, the tool comprising: a tool body; a handle projecting from the tool body; a flashlight carried by the tool body; a pepper spray unit carried by the tool body; and a glass breaker carried by the handle.

A connected portion 68, 68m is disposed at an end of one of a rotary member 41 (first rotary shaft) of a tool unit 10 and a rotary shaft 62a (second rotary shaft) of a driving unit 60, and a connecting portion 52, 52m which is connected to the connected portion 68, 68m is disposed at an end of the other thereof. The connected portion 68, 68m has a guide shaft 68a that rotates integrally with the rotary member 41 or the rotary shaft 62a, and a plurality of engaged portions 68b, 68p disposed around the guide shaft 68a. The connecting portion 52, 52m has a guide hole 52a into which the guide shaft 68a is inserted, and the engaging portions 52b, 52q with which the engaged portions 68b, 68p are engaged and which are disposed around the guide hole 52a.

The invention discloses a multifunctional rigid-flexible operation engineering rescue accessory. The accessory comprises a frame, two working hydraulic cylinders, eight gripping device connecting rods, two gripping claws, a flexible cleaning device base, a movable guide sleeve, a guide slider, a guide slider rail, a rotary guide sleeve, eight sweepers brush, a functional hydraulic cylinder, and a working hydraulic motor. A gravel clearing function and a stone grabbing function are achieved by using one accessory, and different from a traditional engineering accessory integrating rigid movement, the accessory has the advantage of integrating rigid operation and flexible operation. A rigid grabbing system and a flexible sweeping system are arranged outside the frame and in the cavity of the frame respectively, so as to realize function conversion; through pushing out and retracting of a piston of the functional hydraulic cylinder, the sweeping brushes can be pushed out of the cavity to work and retract to be hidden so that the grabbing function and the sweeping function can be rapidly converted; and moreover, working requirements in various working states are met, and motion interference is avoided.

An emergency escape kit is disclosed. The emergency escape kit includes: an emergency escape punch having an obstacle contact portion configured to be in close contact with an obstacle such as a glass window, and configured to shatter the obstacle by pressurizing a side thereof opposite to the obstacle contact portion located between the obstacle and the side of the emergency escape punch; and a gas mask configured to be couplable to or separable from the emergency escape punch, wherein when the gas mask is coupled to the emergency escape punch, the gas mask shields a portion of the emergency escape punch from an outside of the emergency escape punch, and when gas mask is separated from the emergency escape punch and is brought into close contact with respiratory organ of a user, the gas mask prevents external poisonous gas from flowing into the respiratory organ of the user.

The invention relates to 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. The hydraulic unit comprises 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 motor whose axial length extending in parallel to the longitudinal axis of its output shaft is shorter than its outer diameter.

Systems and methods for unified facility communications systems with device location are provided. One system embodiment comprises: a master unit and a plurality of remote antenna units defining a DAS. The master unit communicates with a base station to receive a base station downlink RF signal and to transmit a base station uplink RF signal. The remote antenna units radiate a remote downlink RF signal into a coverage area and receive a remote uplink RF signal from the coverage area. The master unit comprises uplink and downlink circuitry to transport user device communications, and a facility supervisory module to process facility device traffic associated with wireless facility assets in the coverage area. Facility device traffic is transported via the remote antenna units. Within the master unit, user device communications is routed via the uplink and downlink circuitry and facility device traffic is routed via the facility supervisory module.
