    Abstract: A wirelessly locatable tag may be configured to transmit a wireless signal to an electronic device to facilitate localization of the wirelessly locatable tag by the electronic device. The wirelessly locatable tag may include an antenna assembly comprising an antenna frame defining a top surface and a peripheral side surface and an antenna positioned along the peripheral side surface and configured to transmit the wireless signal. The wirelessly locatable tag may further include a frame member coupled to the antenna assembly and defining a battery cavity configured to receive a button cell battery and an enclosure enclosing the antenna assembly and the frame member. The enclosure may include a first housing member formed from a unitary polymer structure and defining a top wall defining an entirety of a top exterior surface of the wirelessly locatable tag.

    Abstract: Methods of defining a virtual fence and for detecting a body inside or outside a region of interest defined by the virtual fence and/or of determining a height for a body on a surface in a region of interest use radar signals and a configuration mode and a monitoring mode are disclosed. In the configuration mode coordinates for defining a virtual fence are determined and/or a topology of a surface in the region of interest is determined. In the monitoring mode, a location of a second body on the surface is detected to determine if the second body is inside or outside the virtual fence and/or a height of for the second body relative to the determined topology is determined.

    Abstract: Systems and methods for operating an Electronic Article Surveillance ("EAS") system. The methods comprise: detecting movement of a plurality of security tags in a facility using Radio Frequency Identification ("RFID"); identifying which security tags of the plurality of security tags are moving towards an exit of the facility or are in a surveillance zone; determining a number of the identified security tags that are coupled to unsold objects; comparing the number to a threshold value; and causing the EAS system to issue an alarm when the number is greater than or equal to the threshold value.

    Abstract: This document describes techniques and devices to detect and classify human and animal presence and/or motion based on changes in the interaction of the human or animal with Wireless Local Area Network (WLAN) radio frequency (RF) signals within or about a building structure, such as a home or office. A first WLAN device transmits a sounding packet to a second WLAN device and receives an acknowledgement (ACK) of receiving the sounding packet by the second WLAN device. The first WLAN device uses the received ACK to determine Channel State Information (CSI) for an RF signal path between the first WLAN device and the second WLAN device, aggregates the determined CSI with additional CSI, and uses the aggregated CSI to determine a presence or a motion within the structure.
