A multifunctional tactical device for fire, police, military and other tactical invasive and protective actions includes: a) a claw head having a ram region and a claw region, the ram region having a top of a predetermined width and a bottom that has a predetermined width that is at least 30% wider than the top predetermined width, the claw head having a front with a flat ram area at the ram region, and having a back with a handle attachment, the claw region having a plurality of claws extending downwardly from the bottom of the ram region; b) an elongated handle member having a proximal end and a distal end and being connected to the claw head handle attachment at the distal end.

A high-rise building escape apparatus enables user to quickly exit a high-rise building in the event of an emergency. It mainly includes a damper which withstands impact of termination of descent and decreases terminal velocity due to its mushroomlike shape, a compartment, side and bottom nets, a parachute, an air source system, hoses, rotatable and fix frames, and a safety belt. The apparatus is operated following the procedure below. A user sets up the fix frame and rotatable frame attaching the dropping parts on the sill of a window or on the top of a balcony, makes the rotatable frame swing to the outside, opens the dropping part pack, fills the high pressure air to the airbags simultaneously through a number of internal hoses and an external hose, and disconnects the hoses. The user then moves from the inside of the building to the compartment in the middle of the damper through the rotatable frame with hands grabbing it, reaches the bottom portion of the compartment, fastens the safety belt, and releases the dropping parts. As a result, the user will move down with the damper, the parachute will be extended, released, and deployed, and the rotatable frame will rotate back. As soon as the user reaches the ground, the user will unbuckle the safety belt, get out of the damper, and release the high pressure air.

An intelligent disaster prevention and escape method includes the steps of: sensing surrounding environment information of plural nodes of a region of a building to generate plural sensing signals of the nodes respectively; calculating a risk coefficient of each node according to the sensing signals; calculating a threat coefficient for plural paths according to the risk coefficients and the distances between the adjacent nodes, for executing an escape path planning algorithm to produce a safest path plan; and producing plural escape instructions for the nodes respectively according to the safest path plan. The invention has the effect of producing the safest path plan according to the risk coefficient and the distance between adjacent nodes, so as to provide safe and immediate escape instructions to guide people to escape and evacuate and reduce casualties.

A vehicle window glass shear system and method for causing shearing breakage of vehicle window glass under emergency conditions by a concealed and easily operated system, having a concealed handle unit having a handle, a handle-unit bracket, and a handle-unit cable brace, having a concealed shear unit mounted on the bottom edge of the vehicle window with a shear-unit bracket, window-clamping plate, and fasteners, a shear bolt with a piercing point, a shear drive wheel, and a shear-unit cable brace, and having a cable within a cable sleeve transferring the activation force from the handle unit to the shear unit, driving the shear bolt toward the vehicle window and driving the piercing point into the vehicle window causing shearing breakage of the window glass.

A fairground ride may include a support structure, at least one vehicle having a passenger receptacle, and at least one guideway which is attached to the support structure and forms a circuit, wherein the guideway is adapted to guide the vehicle along the circuit. The fairground ride may also include at least one drive member which is adapted to move the vehicle along the circuit; and at least one recovery apparatus, which has an operating range. The guideway may be disposed at least section-wise on a substantially vertical area, each point of the normal vector of which is perpendicular to the vertical axis of the support structure, and the operating range of the recovery apparatus may substantially cover the vertical area.

A method, system and computer program product are provided for implementing route generation with augmented reality. A crowd or event is analyzed and escape routes are intelligently distributed by attendee profile type or ability. Augmented Reality (AR) projections are used representing different subsets of an event population to convey the profile-specific escape routes for people to follow. The AR behavior is changed as an event situation changes.

A rescue device for moving a subject includes a brace member for securing the arms and the torso of the subject together. The brace member includes a central section, a first lateral section and a second lateral section, and a fastener. The brace member is capable of forming a loop for securing the arms and the torso of the subject together by fastening the first lateral section to the second lateral section with the fastener. A ribbon member pair for moving and/or stabilizing a subject wearing the brace member when said rescue device is in use includes a first ribbon member having a first portion connected to the brace member and a second ribbon member having a second portion connected to the brace member.
