Abstract: A crowd management system (CMS), is disclosed which includes a command and control (C2) subsystem, a sensor network in communication with the C2 subsystem and adapted to provide signals corresponding to geographical number of individuals in a venue, and one or more crowd management devices (CMDs) further in communication with the C2 subsystem, each of the CMDs including a base adapted to release air at a high pressure, the base further including a positional device adapted to position the base according to a selective position, and an inflatable body terminating into a predefined shape adapted to convey a predefined message to individuals near the CMDs.

Abstract: A separation assembly for use with handheld metal detectors. According to one aspect, the separation assembly is mounted to a handheld metal detector having a blade containing transmission and receiver components of the handheld metal detector. The separation assembly includes at least a first separation member formed of a nonferromagnetic material, and the first separation member is spaced a lateral separation distance from the blade of the handheld metal detector. The separation assembly may be incorporated as a permanent and integrated part of a handheld metal detector, or separately manufactured and installed on a handheld metal detector.

Abstract: Various implementations of a smart battery management system are provided. An example method includes identifying sensor data of a cell in a battery system; predicting, based on the sensor data, a failure event of the cell; and preventing the failure event by activating a control circuit connected to the cell.

Abstract: A system and method suitable for improving the efficiency of a firefighting robot by managing a water supply in a hose coupled thereto is provided. The system includes a robot capable of self-propulsion. The robot is coupled to at least a first hose and is capable of receiving water through the first hose from a water source and discharging the water towards a fire to extinguish the fire. The system includes at least a first valve unit fluidically coupling the first hose to the water source, and means for controlling the robot and the first valve unit such that the first valve unit prevents the robot from receiving water from the water source and drains water from within the first hose when the robot maneuvers and provides water to the robot through the first hose from the water source when the robot is extinguishing the fire.
