Abstract:
An independent back memory module is disclosed that is permanently installed at a security gate installation. The memory module has a nonvolatile memory and it is positioned within the system so that it automatically has a communication link with any gate controller installed. The memory module records a history of the operation of the system. The memory module retains operational information regarding the system and information identifying the gate controller, gate controller board and the setup of the particular installation. The memory module also retains information regarding changes made in the setup of the system. Whenever a new gate controller board is installed information in the memory module is transmitted to the new controller board.
Abstract:
A security system and method is disclosed for use with a security gate entry system that uses a telephone or other communication system at a security gate for communication by a person seeking entry into the secure area with a residence or other unit in the secure area. When a person seeking entry to a limited access area calls on the voice communication system, provided at a security gate entry system a residence or other unit within the secure complex the party answering the call has the option of disguising or altering the voice characteristics of the person answering the call. The system in a preferred embodiment shifts the audio characteristics of a female or child's voice to that of an adult male.
Abstract:
The temperature of an operator circuit is measured. A relationship between the temperature of the operator circuit and characteristics of the operator circuit is determined. The relationship is applied to the measured temperature of the operator circuit to create an adjustment action. The detection threshold is adjusted by the adjustment action.
Abstract:
A system and method of troubleshooting a communication connection for a remotely located security system is disclosed. A communication line test unit is incorporated into the remote security system and its communication unit. A central control unit can then contact the remote security system communication unit, enable the communication line test unit and perform tests on various operational parameters of the communication unit located in the remote unit and the communication connection of the local unit. The tests conducted can include loop current, tip to ring voltage, ring to ground current, circuit loss, circuit noise, power influence as well as other tests. Based on the results of these tests a determination can be made if the problem is an extraneous influence, such as a poor local telephone line connection, or some problem with the security system communication unit itself.
Abstract:
A wireless host access control unit (11) and one or more corresponding wireless remote user interfaces (14) are configured and arranged to participate in a test mode of operation. Pursuant to the test mode of operation, these two system components participate in one or more test transmissions that exercise a wireless transmission link to thereby assess the viability of that link. A corresponding user-discernable test indicator is then provided at the wireless remote user interface. So configured, an installer can test any number of candidate locations for a wireless remote user interface prior to permanently installing that interface, thereby more likely ensuring that the latter will be able to successfully interface with the wireless host access control unit following installation.
Abstract:
A system is disclosed for providing a backup power supply for a security gate system. In a preferred embodiment it includes a primary power supply, an AC motor and an auxiliary DC motor that share the same accessory devices including controller, movement mechanism, sensors, communication unit, etc. The auxiliary DC motor has its own independent DC power supply. If the primary power supply fails the auxiliary power supply takes over and moves the barrier between the open and closed positions as needed without interruption of service.
Abstract:
A method and system for controlling the speed of security gate depending on its length is disclosed. It includes a system for determining the length of a gate that the system is working with and which automatically sets the speed of movement of the gate based on length. The system works automatically so that human intervention is not necessary to set the optimal speed once installed.
Abstract:
A method and apparatus for operating a security gate is disclosed which may comprise a drive mechanism arm having a first end and a second end, and including a security gate attachment member connected to the first end of the drive mechanism arm; a drive mechanism actuator operatively connected directly or indirectly to the drive mechanism arm and adapted to move the drive mechanism arm along a predefined path in relation to the actuator in response to operation of the actuator; and a release mechanism adapted to release the connection of the security gate attachment member to the first end of the drive mechanism arm in response to the application of a force to the security gate attachment member in a direction other than the force applied to the security gate attachment member by the drive mechanism arm in response to the operation of the actuator to move the security gate drive mechanism arm along the predefined path. The apparatus and method may also include a retractor to retract the drive arm after disconnection. The apparatus and method may have an actuator is a linear motion actuator connected directly to the drive mechanism arm, or a rotary motion actuator indirectly connected to the drive mechanism arm.
Abstract:
A method and apparatus for operating a security gate, is disclosed which may comprise a driving member connected to the security gate and adapted to move the security gate from a first position to a second position, responsive to operation of the driving mechanism; a position detection device associated with the operating mechanism and adapted to determine a first distance of the driving mechanism from a first reference point and a second distance of the driving mechanism from a second reference point, and to determine the position of the security gate based upon the relation between the first distance and the second distance. The apparatus and method may have the first reference point being the position of the position detector and the second reference point being at a preselected distance from the position detector. The apparatus and method, further, may have the position detector be an ultrasound, radio frequency or light wave, or the like, transmitter/receiver, and the first distance may be is measured by reflecting waves from a moving target moving as does the driving member and the second distance is measured by reflecting waves from a fixed target fixed in relationship to the transmitter/receiver.
