First position information indicating positions of approaching people nearing merchandise is acquired. Second position information indicating a position of a subject person who has stretched an arm out towards the merchandise among the approaching people, is detected. A movement action performed on the merchandise is detected. An ID of a person corresponding to the subject person who performed the detected movement action is specified based on a positional relationship between the first position information and the second position information.

A method of detecting removal of a maintenance hatch includes transmitting an optical pulse along an optical fiber, wherein a first portion of the optical fiber is proximate to the maintenance hatch. The method further includes detecting backscatter light from the optical fiber using a sensor. The method further includes determining information related to the first portion of the optical fiber based on a comparison of the detected backscatter light and a trained model. The method further includes identifying whether the maintenance hatch has been removed based on the determined information.

A signal-emitting retail display device that includes a wire having a top portion and a bottom portion, the top portion configured to support a label holder, the bottom portion configured to store one or more retail items. The signal-emitting retail display device also has an electronic unit that includes an emitter. The emitter is configured to emit an audible alarm or warning signal, and configured to wirelessly transmit a signal to a remotely-located alarm box indicative of the audible alarm or warning signal. The wire is electrically coupled to the electronic unit such that the wire functions as an antenna for the transmission of the signal to the alarm box.

The invention relates to a life vest container device, in particular aircraft seat life vest container device, for a life vest unit, with a life vest container comprising an accommodation unit that has an accommodation space as well as an access opening to the accommodation space, and with a monitoring device.

It is proposed that the monitoring device is at least configured to capture a change of at least one characteristic via at least one electric and/or electronic signal.

A detection system for measuring one or more conditions within a predetermined area includes a fiber harness having at least one fiber optic cable for transmitting light, the at least one fiber optic cable defining a node arranged to measure the one or more conditions. A control system is operably coupled to the fiber harness such that scattered light associated with the node is transmitted to the control system, wherein the control system analyzes the scattered light to determine at least one of a presence and magnitude of the one or more conditions at the node. An optical enhancement device is operably connected to the fiber harness or to the control system to reduce interference sources transmitted from the node.

A fiber optic tamper switch is disclosed, wherein a moveable member is moved to actuate the switch. The switch includes a component subassembly block and a cover. The switch includes a toggle arm extending through the cover, contacting the moveable member and configured to rotate when the moveable member is moved. The switch includes a fiber capture bar configured to receive a fiber optic cable and a fiber press bar coupled to the fiber capture bar configured to actuate upon the movement of the toggle arm and translate the fiber capture bar in a first direction, effecting a bend in the fiber optic cable. The fiber optic cable is configured to attenuate a light signal when bent. The switch includes a locking mechanism preventing the unbending of the fiber optic cable.

A computer-implemented event statistic generation for intrusion detection comprises processing a plurality of return signals from a coherent optical time-domain reflectometer into time-domain signals for each of a plurality of sensor bins, the plurality of return signals corresponding to a plurality of stimulation pulses injected into an optical sensor fiber during a time period. For each sensor bin, transforming the respective time-domain signal into a corresponding frequency-domain signal, calculating, from the respective frequency-domain signal, a first signal power area of a first frequency band expected to contain system noise and a second signal power area of a second frequency band expected to contain any energy related to at least a first event; and generating an event statistic proportional to the ratio of the second signal power area to the first signal power area at least in part by dividing the second signal power area by the first signal power area.
