Abstract: An event detection unit (EDU) for detecting an explosive event is provided. The EDU includes different types of sensors for measuring characteristics of an explosive event. The EDU includes an event notification component. The EDU also includes a processor that receives a measurement from the sensors and generates a combined non-event probability and a combined event probability based on that measurement that indicates a likelihood that an explosive event has not occurred or has occurred. The processor determines whether an explosive event has occurred based on the non-event probabilities and event probabilities. When an explosive event has been determined to occur, the processor directs the event notification component to output a notification that an explosive event has occurred.

Abstract: A mouth guard senses impact forces and determines if the forces exceed an impact threshold. If so, the mouth guard notifies the user of the risk for injury by haptic feedback, vibratory feedback, and/or audible feedback. The mouth guard system may also remotely communicate the status of risk and the potential injury. The mouth guard uses a local memory device to store impact thresholds based on personal biometric information obtained from the user and compares the sensed forces relative to those threshold values. The mouth guard and its electrical components on the printed circuit board are custom manufactured for the user such that the mouth guard provides a comfortable and reliable fit, while ensuring exceptional performance.

As may be implemented in accordance with one or more embodiments, objects in a local environment are scanned with laser light, and reflections of the scanned laser light from the objects are received and processed to generate a 3D image of the local environment. Distance and velocity of each object is provided or detected based on a frequency delay and frequency shift of one or more reflections of the scanned laser light from the object. For instance, the 3D image may provide relative position of an object and indicate velocity of the object, which may be ascertained based on a frequency shift.

Abstract: A fire detector is connected to a loop transmission line connected to a receiver. When the loop transmission line is normal, a transmission unit is connected to the fire detector. When a disconnection failure occurs, a disconnection monitoring unit turns on switching circuits to connect the end of the loop transmission line to the transmission unit, and the receiver connects to the fire detector from both ends of the loop transmission line. An input/output switching booster is inserted and connected in the middle of the loop transmission line, and when the start side transmission line is disconnected and the switching circuits are turned on, the input/output is switched. Accordingly, the input/output switching booster amplifies the down signal input from the terminal side transmission line and outputs it to the start side transmission line and at the same time amplifies the up signal input from the start side transmission line.

Abstract: In an Electronic Article Surveillance (EAS), a radio frequency identification (RFID) subsystem of an EAS system, can detect a presence of an RFID tag in an RFID interrogation zone associated with a boundary of a controlled area. The EAS system can first determine that the RFID tag is not authorized to leave the controlled area across the boundary. A radar subsystem of the EAS system can second determine, within a first window of time around the first detecting, whether an object in motion is associated with the boundary. The EAS system can alarm based upon both determining that the RFID tag is not authorized to leave the controlled area and determining that the object in motion is associated with the boundary.
