A railroad crossing safety assembly includes a plurality of object sensors that is each positioned on a respective one of four corners of a railroad crossing. The object sensors emit a sensing signal across the railroad crossing to detect an obstruction on the railroad crossing. A data storage unit is provided and each of the object sensors is in electrical communication with the data storage unit. The data storage unit is in electrical communication with emergency responders thereby facilitating the emergency responders to be notified of the obstruction on the railroad crossing. Additionally, the data storage unit is in communication with a railway operation department thereby facilitating the railway operation department to alter railway scheduling in response to the obstruction.

A method for detecting motion is provided. The method includes: detecting a motion of a body in order to generate motion data; detecting a location of an allowed movable body in order to generate location data; and determining whether the motion of the body is a motion of the allowed movable body based on at least the motion data and the location data. A security system for verifying a detected motion is also provided. The system includes: a motion detection system; a location detection system; and a processing unit configured to determine whether motion detected by the motion detection system is a motion of the allowed movable body. The system may be for performing the method of detecting motion.

A method and a target monitoring system (TMS) to generate descriptive parameters of one or more target objects in a region are provided. The TMS dynamically receives first data comprising image data and/or audio data of the target objects in the region and second data comprising circumstantial information related to the first data from one or more sensors positioned in one or more spatial directions in the region over a network. The TMS filters the dynamically received first data and identifies the target objects in the region using image data extracted from the filtered data. The TMS generates descriptive parameters associated with each identified target object in the region using the filtered first data and the circumstantial information.

A package deposit enclosure designed for public use is powered by an efficient storage battery and photovoltaic cell array. These unique features allow the package deposit enclosure to be placed in locations where no power is available, but where there is frequent human traffic. Sensing and wireless data communication features allow the unit to be emptied less often than typical package delivery enclosures. Wireless communication also allows users' access to real-time information. On board power enables other functions, such as lighting and audio, to enhance device functionality.

Described herein is a method and system of distributed acoustic sensing, such as in an urban or metropolitan area involving a dedicated and established fibre optic communications network including a data centre. In general, the disclosed method and system includes the steps of (a) selecting an optical fibre cable installation having a path extending across a selected geographical area, the optical fibre cable installation including a bundle of optical fibres and forming part of a fibre-optic communications network, (b) determining characteristics associated with the optical fibre and/or the selected optical fibre installation, (c) transmitting outgoing light in the optical fibre, (d) receiving reflected light back scattered along the optical fibre, and (e) based on the reflected light and the determined characteristics, generating an alert signal representative of an acoustic event. The disclosed method and system is thereby configured to detect acoustic events near or within the selected geographical area.

A circuit device includes an A/D conversion section adapted to output temperature detection data, a temperature compensation section adapted to perform a temperature compensation process of the oscillation frequency based on the temperature detection data, and an oscillation signal generation circuit adapted to generate an oscillation signal using frequency control data from the temperature compensation section and a resonator. The frequency control data from the temperature compensation section is input to the oscillation signal generation circuit during a normal operation, and during a period other than the normal operation, data generated by a PLL circuit for comparing an input signal based on an output signal of the oscillation signal generation circuit and a reference signal with each other is input to the oscillation signal generation circuit.
