Abstract: A computer implemented method includes initiating, by at least one processor within a computing environment, operation of a virtual camera and an SFU; receiving, by the SFU, a plurality of audio streams from a plurality of remote devices; communicating, by the SFU, the plurality of audio streams to the virtual camera; receiving, by the virtual camera, the plurality of audio streams from the SFU; mixing, by the virtual camera, the plurality of audio streams into a single audio stream; communicating, by the virtual camera, the single audio stream to a physical image capture device; and receiving, by the virtual camera, an audiovisual stream from the physical image capture device.

Abstract: An inventory of goods is protected from theft by means of electronic article surveillance (EAS) markers integrated with items of the inventory. Each such item has a structural member in which a cavity is integrally formed. A respective magnetostrictive element is housed, free of mechanically clamping constraint, in each cavity. A respective biasing element is located adjacent to the cavity on each such item of inventory. The biasing element provides a magnetic field to bias the respective magnetostrictive element. EAS equipment is provided at a retail store where the inventory is maintained. The EAS equipment generates an alternating electromagnetic interrogation field, and when an item of inventory having the integrated EAS marker is exposed to the interrogation field, the biased magnetostrictive element is excited into mechanical resonance that is detected by the EAS equipment.

Abstract: A theft deterrent tag for protecting an article is disclosed wherein the tag comprises a tag body, a tack-like assembly for securing the tag body to an article and a cutting blade for cutting the article upon a preselected force being applied to the tag body or the tack-like assembly.
