An electronic article surveillance device with an electronics housing and base attaches to an article to be protected. The housing and base have connecting interfaces which act together to attach the housing to the base. The housing has a switch on the underside and the base has an aperture partially covered by a flexible tab that aligns with the switch. The flexible tab normally protrudes away from the bottom surface of the base. When the base is attached to an article, the tab is pushed back into the aperture. When the housing is attached to the base, the switch contacts the tab. If the EAS device is removed from the base without disarming the device, the tab moves out of the aperture and allows the switch to detect the removal. The EAS device then issues an alarm. The flexible tab may a piercing element to pierce plastic wrapping, if present.

An anti-theft device for monitoring Type C USB connector. An alarm module has a first terminal and a second terminal. A male plug has a first conductive member in electrical communication with the first terminal and a second conductive member in electrical communication with the second terminal. When the male plug is positioned within the receptacle, a closed electric circuit forms between the first and second conductive members. The alarm module supplies an electric current to the first terminal and monitors the electric current flowing to the second terminal. Responsive to detecting an interruption in the electric current flowing between the first and the second terminals, the alarm module transmits an alarm signal.

Embodiments of the present invention are directed to merchandise security systems and methods for displaying and protecting an article of merchandise from theft. In one example, the system includes a sensor configured to be secured to the article of merchandise, wherein the sensor includes alarming circuitry. The system also includes a tether comprising a pair of conductors electrically connected to the alarming circuitry, wherein the pair of conductors is configured to transfer power to the sensor and/or to the article of merchandise. In response to power ceasing to be transferred, the alarming circuitry is configured to monitor an electrical signal transmitted through the pair of conductors in order to determine whether the tether has been cut or removed from the sensor.

A sensor for a merchandise display security system for displaying and protecting an article of merchandise is provided. The security system includes a merchandise bracket configured to be secured to the article of merchandise and a sensor configured to releasably engage the merchandise bracket and to detect unauthorized removal of the merchandise bracket or the sensor from the article of merchandise. The sensor is configured to be releasably engaged with the merchandise bracket such that the sensor is removable from the merchandise bracket while the merchandise bracket remains secured to the article of merchandise.

A sensor system for monitoring an object, including at least one first part and one second part, of which one is a sensor module having at least one sensor, and at least one fastener to fasten the first part to the object to be monitored, wherein the first part and the second part are designed to establish a releasable connection between the second part and the first part and wherein one of the parts is equipped with a signaling device, which is designed to detect a release of the connection between the second part and the first part and to produce a signal triggered thereby, wherein the fastening of the first part to the object cannot be released nondestructively in a state in which the connection between the second part and the first part exists.

Embodiments of the present invention are directed to merchandise display systems and methods for displaying an article of merchandise. In one example, the system includes a sensor configured to be secured to the article of merchandise. The sensor includes a first engagement member. The system also includes a base configured to removably support the sensor thereon. The base includes a second engagement member configured to releasably engage the first engagement member such that the sensor is locked to the base. The sensor is configured to rotate with respect to the base while locked thereto.

A point of sale assembly having antitheft functionality. A sealed consumer product package has a face with at least one opening extending into the sealed consumer product package. A consumer product is positioned inside the sealed consumer product package. A lock having a sensor and a body that is positioned outside the sealed consumer product package. The lock has at least one locking arm extending into the opening of the sealed consumer product package and secured to the consumer product.

Embodiments of the present invention are directed to merchandise display systems and methods for displaying an article of merchandise. In one example, the system includes a sensor configured to be secured to the article of merchandise. The system also includes a base configured to removably support the sensor thereon. The base includes a lock mechanism configured to lock the sensor to the base.

Embodiments of the present invention are directed to security systems and methods for securing an item of merchandise from theft or unauthorized removal. For example, the security system may include a sensor configured to be coupled to the item of merchandise and a charging circuit for providing power to the sensor and/or the item of merchandise. The security system may also include a cable connected to the sensor and at least one optical transceiver for defining a sense loop between the cable and the sensor.

A security device is provided that includes an electronic article surveillance tag that may be configured to resonate to provide a wireless response signal to a deactivator to trigger generation of a deactivation field. Further, the security device may include tamper detection circuitry which may include a tamper sensor configured to generate a tamper signal in response to detecting a tamper event, a deactivation sensor configured to generate a deactivation signal in response to detecting the deactivation field, and a sounder. In this regard, the tamper detection circuitry may be configured to deactivate the tamper detection circuitry in response to receiving the deactivation signal from the deactivation sensor such that receipt of the tamper signal after deactivation of the tamper detection circuitry does not trigger the sounder to emit the alarm.
