The present application relates to the field of logistics, discloses an anti-disassembly logistics appliance and anti-disassembly method therefor, realizing the anti-disassembly alarm of a designated module under the premise of simple structure and low power consumption. An anti-disassembly logistics appliance, comprising: a confined space and an anti-disassembly module disposed in the confined space; the anti-disassembly module comprises: one or more photoelectric devices, a wireless communication unit and a determining unit; the determining unit is configured to determine whether an electrical signal output by the photoelectric device is greater than a preset threshold, and if so, triggers the wireless communication unit to transmit an alarm signal; the structure of the confined space satisfies following requirements: the confined space is an light-tight dark space after the anti-disassembly module is installed; during the process of disassembling the anti-disassembly module from the logistics appliance, the light-tightness of the confined space is at least temporarily destroyed to enable the optoelectronic device to detect light.

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 method of operating an activity recognition system includes capturing ambient radio frequency (RF) data by an RF sniffer. The ambient RF data is then received by a processor. The processor reduces noise content of the ambient RF data. Background is then subtracted from the ambient RF data by the processor. The processed ambient RF data is then converted into an image by the processor. The system generates successive images for each one of a plurality of time intervals. An image processing algorithm, stored in a storage medium and executed by the processor, is applied to the plurality of successive images to determine activity recognition.
