Abstract:
One embodiment of the line monitoring system (100) may include an object identifying and locating system (120) to identify and locate objects (102a-102e) in the surveillance area (104) and an object analysis system (130) to analyze the behavior of the objects and determine if the objects form a line. The object identifying and locating system (120) may generate object data including, but not limited to, object identifying data (e.g., an ID number) and object locating data (e.g., coordinates). The object analysis system (130) may receive the object data and analyze the position and movement of the objects to determine if objects exhibit behavior indicating that the objects should be designated as being in a line, as will be described in greater detail below. As shown, objects (102a, 102b) maybe designated as in a line, while objects (102c-102e) may not yet be designated as in a line.
Abstract:
A dehumidified equipment housing may be used to house equipment including one o more mechanical devices and/or electronic devices. The dehumidified equipment housing may prevent condensation on one or more regions inside of the housing and may control condensation inside of the housing to provide a dehumidified environment inside of the housing. The dehumidified equipment housing may also remove condensed water to outside of the housing.
Abstract:
An electronic article surveillance (EAS) antenna system including at least one transmit antenna and at least one amorphous core receiver antenna adapted for installation on the floor, in the grout region of the floor, or under the flooring of a passageway. An EAS system including at least one perimeter loop antenna adapted to extend around the entire perimeter of a passageway is also provided. The system may further include at least one floor antenna adapted for installation within a region of a floor of a passageway and at least one ceiling antenna adapted for installation adjacent a ceiling of the passageway.
Abstract:
The multiple image video surveillance camera system that uses a common set of sequencing logic to sample multiple imaging devices or multiple pre-set image windows within a large high-resolution imaging device is provided (32, 34 of fig. 2). The images are multiplexed into a single frame or switched on a frame-by-frame basis at the imaging device. The switched frames are marked or encoded (36 of fig. 2) to facilitate separation for individual image display. This configuration allows one camera processor or sequencer to support multiple imagers and eliminates the need for a separate multiplexer, which lowers the system cost. Using a single transmission media (36 of fig. 2) to the video recording or display devices significantly reduces system installation cost.
Abstract:
An electronic key capable of reinitializing or resetting a security disabled electronic article surveillance (EAS) device is provided. The electronic key can be a secure, portable, and battery powered for initializing a secured EAS system's security protocol to factory default state, or to another preselected state. The key has its own set of security protocols to prevent unauthorized use and can easily be reprogrammed for a wide variety of other functions including, but not limited to, firmware upgrading, diagnostic testing, and the like. The key can be connected to the programming port of an EAS device and perform a preset reprogramming operation, resetting activated security features. The key could be purchased for customer use, and would be secured by pre-selecting the total number of uses, such as one use. The one-time use would begin once the key is activated. Activation of the key is also uniquely controlled to prevent its misuse. In one embodiment, the electronic key must detect the interrogation field of a properly functioning EAS exit system prior to becoming enabled. The allowed usage can be limited by time, the number of units reprogrammed, or a combination of both. Once the key has been activated for its pre-selected number of uses and shuts off, only qualified service personnel can reset the electronic key function for further uses.
Abstract:
A method for wireless synchronization of first (A) and second (B) magnetic electronic article surveillance (EAS) systems arranged for operation in close proximity to one another, comprising the steps of: programming each of the first and second EAS systems for transmitting at least one unique signal into respective and partially overlapping interrogation zones of the first and second EAS systems and for receiving any signals from the interrogation zones at respective and predetermined transmit and receive phases relative to a common reference; transmitting a unique signal from the first EAS system (30); receiving and identifying the at least one unique signal at the second EAS system during one of the receiver phases (50C); and, transmitting from the second EAS system synchronously with the transmitting from the first EAS system, responsive to the conveyed phase information (32).
Abstract:
A cordless handheld EAS tag deactivator is provided. The deactivator is housed in a portable handheld housing. An antenna is attached to the housing. The antenna is adapted for transmission of an electromagnetic field, which deactivates EAS tags within the field. An electronic circuit is connected to the antenna to generate the electromagnetic field. A battery contained within the housing is connected to the electronic circuit to power the generation and transmission of the electromagnetic field.
Abstract:
A number of synchronized low-cost camera nodes (2) sharing a single cable (4) to reduce cost associated with wiring, installation, cameras, video multiplexer and mounting is provided. Each camera node is individually addressable through a single cable to transmit an externally frame snychronized video signal onto the cable. A plurality of camera nodes can thus be wired along a single cable with each camera node individually selectable for receiving its video signal on the cable.
Abstract:
The invention concerns a system for detecting multiple tags in a detection zone. The system includes an electronic tag detection system having first and second field generators, each having a respective antenna for generating an electromagnetic field in a detection zone defined between the antennas. Additionally, at least one of the field generators can be responsive to a presence of at least two electronically detectable tags in the detection zone, for varying an intensity of at least one of the electromagnetic fields.
Abstract:
A surveillance apparatus for use in a camera surveillance system, the surveillance apparatus being microprocessor controlled and including an image blanking unit provided to establish privacy zones in which the video images of the surveillance apparatus are partially or totally blanked out to obscure viewing by an operator. The privacy zones are established by designating triangular areas of the image.
