An electronically lockable, electrical plug configured to communicate power and data signals to mobile electronic devices (MED) includes a male electrical plug body insertable into a female electrical socket of the MED and plurality of electrical contacts defined in the male electrical plug for communicating the power and data signals to and from the MED, via corresponding electrical contacts associated with an MED electrical socket. The MED electrical socket is shaped and sized to physically receive and support therein said male electrical plug body. Plug locking elements are formed in the male plug body are so formed as to be lockable to or with corresponding, complementary socket locking elements of the MED, so that upon insertion of the male plug body into the MED socket the electrical plug is locked with the MED An associated, electronically operable locking mechanism is operable to mechanically disengage the plug locking elements from the socket locking elements to thereby enable the electrical plug to be released from the MED and an electrical cable is coupled to the male plug body for electrically conducting the signals.

A universal security lock for portable electronic devices has an engaging mechanism which has a base, an expanding rod, and two gripping fingers. The expanding rod is slidable along an engaging direction. Each of the gripping fingers is pivotally mounted on the base and disposed on a respective side of the expanding rod. When the expanding rod is moved toward the engaging direction, an end of the expanding rod abuts against the two gripping fingers and expands the gripping fingers gradually such that the gripping fingers can be engaged in security slots of a portable electronic device. At least one of the gripping fingers has a protrusion extending toward the other gripping finger. The expanding rod selectively abuts against the protrusion to further expand the gripping finger.

A universal security lock for portable electronic devices has a lock case and a lock core. The lock core, a displacement absorber, an expanding rod, and two gripping fingers are arranged in a passage of the lock case. An operating part of the lock core is movable inwardly into the passage to an engaged position. The displacement absorber is a spring or two mutually repelling magnets that drive the operating part and the expanding rod to move away from each other. The two gripping fingers are pivotally mounted on a front opening of the lock case. When the operating part is in the engaged position, the displacement absorber pushes the expanding rod toward the front opening to move the outer ends of the two gripping fingers away from each other gradually such that the gripping fingers engage with security slots of different widths.

A universal security lock for portable electronic devices has a base and a lock core. An operating part, a blocker, a displacement absorber, an expanding rod, and two gripping fingers are arranged in the base. The operating part is slidably mounted through the rear opening and is slidable toward the front opening to an engaged position. The displacement absorber is a spring or two mutually repelling magnets that drive the operating part and the expanding rod away from each other. The two gripping fingers are pivotally mounted to the base and disposed on a front opening of the base. When the operating part is in the engaged position, the displacement absorber pushes the expanding rod toward the front opening to move the outer ends of the two gripping fingers away from each other gradually such that the gripping fingers engage with security slots of different widths.

An apparatus for securely displaying a product includes a cradle assembly including a base plate and a plurality of plates slidably engaged with the base plate, each plate of the plurality of plates including an arm to engage a respective side of the product, and a post supporting the cradle assembly, the post including first and second sections, one of the first and second sections being fixedly connected to the base plate. The first section includes a projection, and the second section includes a guide in which the projection is disposed to control rotation of the first and second sections relative to one another and re-orient the cradle assembly.

Security systems and methods configured for use with an item of merchandise for retail display are provided. For example, a security system includes a sensor configured to be electrically connected to an internal power source of an item of merchandise and an alarm module configured to communicate with the sensor. The sensor is configured to receive power from the internal power source for performing one or more security functions, and the alarm module is configured to generate a security signal in response to a security event.

An anti-theft lock for a portable electronic device has a mounting shaft, two buckling units, a split-abutting unit, and a controlling unit. The two buckling units are moveably mounted around the mounting shaft. The split-abutting unit is moveable and has an engaging end and a split-abutting end. The split-abutting end selectively abuts the two buckling units via the movement of the split-abutting unit. The controlling unit has an annular curved surface. The annular curved surface slidably abuts the engaging end of the split-abutting unit. During the rotation of the controlling unit, the annular curved surface is capable of pushing the split-abutting unit to make the split-abutting end abut the two buckling units with inclined surfaces to move the two buckling units away from each other. The larger a distance the split-abutting unit moves, the larger a distance the two buckling units move away from each other.

Embodiments of the present invention are directed to recoilers, merchandise security systems, and methods for displaying and protecting an article of merchandise from theft. In one example, the merchandise security system includes a sensor configured to be secured to the article of merchandise and a base for removably supporting the sensor and the item of merchandise thereon. The system also includes a recoiler operably coupled to the sensor. The recoiler includes a rotatable member defining a helical recess. The system further includes a cable configured to connect to the sensor and to be unwound from and wound on the rotatable member as the cable is extended and retracted. The cable is configured to be extended from the recoiler in response to the sensor being lifted off of the base, and the cable is configured to be retracted into the recoiler in response to the sensor being moved to a seated position on the base. The helical recess is configured to at least partially receive the cable therein as the cable is wound on the rotatable member.

A lock assembly for preventing theft of an electronic mobile device (EMD) is configured to engage a security cavity formed in the 2 mm thick outer wall of the EMD. The security cavity has left and right outwardly-flaring side walls extending away from the opening. The lock body supports first and second locking elements, each of which is configured to be insertable into the security cavity and has an arcuately-shaped side wall that is complementary in shape to the right/left outwardly flaring side wall of the security cavity. The first and second locking elements cooperate structurally to become wedged inside the security cavity in manner that prevents separation of the lock body from the EMD while the first and second locking elements are positioned inside the security cavity. Preferably, the arcuately-shaped sides of the locking elements extend over an arc angle of 180 degrees. A cable is coupled to the lock body to enable tethering the EMD to an immovable object, to prevent its theft.

A cooler and freezer access control system locks a cooler or freezer when occurrence of an event is detected that requires limiting access to the inside of the cooler or freezer. Examples of such events include the loss of power to the cooler or freezer for a predetermined period of time, the opening of the cooler or freezer door for longer than an allowed time, the loss of functionality of a temperature probe and others. In an embodiment, a service mode is supported wherein the door is left unlocked despite the occurrence of such an event, to allow a stocker or other personnel to leave the cooler or freezer door open while stocking the cooler or freezer with product.
