摘要:
Systems and methods for reducing an overpressure caused by an explosion of a vapor cloud are provided. In one or more embodiments, the system can include one or more sensors operable to detect the explosion of the vapor cloud. The system can also include one or more igniters operable to ignite the vapor cloud at locations throughout, after the explosion of the vapor cloud is detected, to provide a discrete combustion zone at each location. Each combustion zone can form a discrete pressure wave, thereby reducing the overpressure caused by the explosion of the vapor cloud.

The invention relates to an extinguishing device designed for local firefighting in buildings on site at the source of a fire, said extinguishing device having a nozzle device having an extinguishing unit comprising a plurality of extinguishing nozzles designed for applying an extinguishing agent at the location of the source of the fire and for decentralized arrangement in the building, further comprising at least one extinguishing agent container connected to the extinguishing nozzles in a fluid-communicating fashion, at least one pressure-generating device for applying the extinguishing agent via the extinguishing nozzles, and at least one fire alarm sensor. According to the invention, the pressure-generating device is designed to generate an application pressure of at least 10 bar on the extinguishing agent.

An unmanned aerial vehicle (UAV) designed to extinguish fires from the air while remaining tethered to the ground via a tether system fashioned to provide the UAV with power and extinguishant. The UAV is preferably electrically powered and is stabilized in the air via a system of gyroscopes fashioned to work in concert with a series of electric motors capable of moving to counteract the opposing recoil force exhibited as water escapes the nozzle of the tether. A command and control unit on the ground supplies the UAV with electricity and water via the tether. The UAV is preferably stored within and launched from the command and control unit. Controls and sensor readings are communicated to a controller—be it autonomous or human—on the ground, preferably within or proximal to the command and control unit.

A quick release interconnect and locking device having a base plate with a post A circular and planar D-shaped disc is disposed on an end of the post. The apparatus has a female element with a contoured channel. A keeper plate with a vertical slot is placed over the contoured channel. A medial portion of the contoured channel includes an upper locking face terminating at a lower end in radius, such that when the D-disc is aligned parallel with the upper locking face, the D-disc may be translated downwardly until it encounters a locking portion, where it may again be rotated to bring the sliding face into alignment with a locking face and may then be translated downwardly to a semi-circular portion at the bottom of the contoured channel, where it may be rotated to lock it in the lower locking portion.

A light emitting device (1), which is adapted to be attached to at least one air cylinder (2, 3) that is to be carried by a diver, such as a scuba diver or a smoke diver, comprises an electroluminescent filament and a protective cover enclosing the filament and made of translucent, heat resistant silicone material. The light emitting device (1) further comprises resilient fastening elements (4a, 4b), which are arranged to secure the light emitting device (1) to the air cylinder/cylinders (2, 3) by a force determined by the resilient properties of the fastening elements.

The invention provides an actuator apparatus which may be used to adjust flow of fluid or air in conjunction with a rack and pinion system. The device is able to rotate both vertically and horizontally via a mechanism that transforms axial movement into rotary movement. The device is useful in a range of circumstances where required specific and controllable rotary motion is required.

This invention relates to safety equipment used by fire fighters and other emergency response workers. In one example, the invention includes a portable electronic fire fighter's equipment, such as a door chock, that has electronic sensor and communication capabilities.
摘要:
A method for identifying available resources for responding to an incident is provided. The method includes receiving a communication from each of a plurality of first responders, where the communication is responsive to an incident generated request, processing each of the communications to generate a response status for each of the plurality of first responders, and sending the response status for each of the plurality of first responders to a remote program.
摘要:
The invention relates to a device for measuring time-resolved volumetric throughflow processes, especially injection process in internal combustion engines, having a translational volume difference sensor having a piston disposed in a measuring compartment and a detection device detecting the excursion of the piston, the detection device being linked with an evaluation unit. According to the invention, a pressure sensor is mounted in the measuring compartment in addition to the detection device which detects the excursion of the piston. The signal of the detection device corresponding to the excursion of the piston can be better evaluated as the compressivity of the fluid in the measuring compartment can be taken into consideration for the calculation of the amount to be injected. The inventive device allows for a highly time-resolved representation of throughflow processes so that both overall amount and exact course of the throughflow can be represented and evaluated.
