Abstract: A security device for locking a merchandise display rod to a support structure. The device includes a housing slidably received on the display rod and including a locking mechanism movable between a locked and an unlocked position. The housing defines a recess extending inwardly from an exterior surface thereof and perpendicularly to the linear motion of a locking member in the locking mechanism. A complementary shaped dipole magnet of a magnetic key is inserted into the recess to move the locking mechanism to the unlocked position. The security device further includes an adjustment member on a rear surface thereof. The adjustment member is engaged to compensate for different thicknesses of the support structure to which the security device is to be attached.

Abstract: An optical disc structure for playback by a read-out device is described. The optical disc structure includes a first layer with first content recorded thereon. A second layer is coupled to the first layer. The second layer has first content and second content recorded thereon. The disc of the present principles makes use of the fact that a less than full capacity DVD9 disc leaves available recording space after the end of program area and required lead-out area on the second of the two data layers of a DVD9 disc.

Abstract: A method is disclosed for securing sensitive material on a computer system comprising a network of computers from unauthorized access by a root level user of the computer system, the method including the steps of: limiting access to the sensitive material to one or more authorized users; controlling the operation of one or more system functions to prevent unauthorized access to the sensitive material.

Abstract: The invention provides hard coat and image receiving layer structures and related methods used in ID document production. These structures and methods provide ID documents that offer hard protection in areas where needed (e.g., in optical windows for machine readable data), and also provide image receiving layers for later printing of variable data, such as personalization information of the bearer. Implementations of the structure provide an effective interface between hard coat and image receiving layers that provides enhanced durability in manufacture and field use.

Abstract: A method and a system for determining a return fraud at a store are described. The return fraud protection system has a video recording module, a face capture module, a face icon generator module, and an entrance video clip module. The video recording module records a video at an entrance of the store. The face capture module captures a face of a customer entering the store from the video. The face icon generator module generates a face icon comprising the face of the customer. The entrance video clip generator module generates a video clip of the customer entering the store, associates the video clip of the customer with the corresponding face icon, and provides a client device with a list of face icons with corresponding video clips.

Abstract: A display case system has a display case, a gateway, and a communication device. The display case houses a product. The gateway is coupled to the display case and communicates with a client device associated with the product in the display case. A communication device is coupled to the gateway and enables a communication session between the communication device and the client device associated with the product. The client device remotely locks and unlocks the display case to allow access to the product based on the communication session.

Abstract: A method of decomposing a set of scans of different views of overlapping objects into constituent objects is presented. The method involves an initialization process whereby keypoints in two views are determined and matched, disparity between keypoint pairs are computed, and the keypoints are grouped into clusters based on their disparities. Following the initialization process is an iterative optimization process whereby a cost function is calculated and minimized assuming a fixed composition matrix and re-solved assuming a fixed attenuation coefficient. Then, the composition matrix and the attenuation coefficient are updated simultaneously, and the solving, the re-solving, and the updating steps are repeated until there is no significant improvement in the result.

Abstract: A merchandise display hook includes a display rod and a locking base pivotally attached to the display rod for locking the display hook on a display support. The locking base is configured to pivot relative to the display rod inwardly towards the display support from an unlocked position to a locked position and outwardly from the display support from the locked position to the unlocked position. The display hook includes a first attachment member configured to engage a front surface of the display support and a second attachment member configured to engage a rear surface of the display support. The locking base defines a contact surface configured to engage the front surface of the display support in the locked position. When the locking base is in the locked position, the locking base and the display rod define a first angle therebetween. When the locking base is in the unlocked position, the locking base and the display rod define a second angle therebetween that is less than the first angle.

The management application has a service manager module to enable additional services from the gateway and the security device. The client device communicates with the gateway identified by the web server. The gateway aggregates monitoring data from the security device and from other security devices respectively coupled to other gateways correlated with the gateway. The client device receives the aggregated monitoring data, controls the security device coupled to the respective gateway from a web-based user interface at the client device.

Abstract: A door position detecting apparatus comprises a switch including a body having two electrical contacts and a through-channel. The through-channel of the switch receives a hinge pin inserted therethrough and further inserted into a door hinge. Two lever arms extend from the body. Each of the arms is attached to a respective one of the electrical contacts. The arms have a first position relative to each other wherein the contacts are electrically connected to each other, and a second position relative to each other wherein the contacts are electrically disconnected from each other. Biasing means biases the arms against a fixed door jamb and a rotatable door, respectively, such that one of the arms follows movement of the rotatable door from an open position of the door to a closed position of the door. Monitoring means monitors whether the contacts are electrically connected to each other.

Abstract: A locking device for a merchandise display hook has an upper rod disposed along a longitudinal axis and a lower rod disposed generally parallel to the longitudinal axis and the upper rod. The locking device includes a housing having a vertical slot adapted to receive the upper rod and the lower rod of the display hook. A bayonet is movable between a locked position in which a portion of the bayonet extends into the slot and restricts movement of at least one of the upper rod and the lower rod within the slot, and an unlocked position in which the bayonet does not extend into the slot and thereby permits movement of the upper rod and the lower rod within the slot. An elongate nose depending outwardly from the housing defines a channel that intersects the slot of the housing and receives the upper rod of the display hook with the upper rod and the lower rod disposed within the slot.
