Abstract: The present invention advantageously provides a method and system that combines arming and disarming of a security system with activation and deactivation of call forwarding, enabling a single input by an authorized user to alter the state of the security system and to activate or deactivate call forwarding. Further, when changing the state of the security system, a user authorization component determines whether call forwarding should be activated. Hence, forwarding of calls is based on both user criteria and the state of the system. Additionally, the state of call forwarding can be changed by an authorized user via the security system.

Abstract: Line load compensation and reflection reduction in a signal transmitting circuit is provided using feedback capacitors. The feedback capacitor serially coupled with a resistance generates an RC rise/fall time that is independent of the line load. Additionally, by selecting a capacitor that yields a rise/fall time of approximately ? of the maximum bit transmission time, signal reflection on the signal line can be reduced. Accordingly, by incorporating the feedback capacitor with a differential drive circuit, such as the IB 485 driver, variations in line load can be compensated for while also reducing signal reflection due to un-terminated or improperly terminated signal lines, thus allowing a free topology implementation.

Abstract: A security device including a control panel for transmitting a pre-defined cadence pattern to a siren device. The siren device takes the pre-defined cadence pattern as an input and outputs an audible voice message that corresponds to the pre-defined cadence pattern. The siren device is capable of recognizing the pre-defined cadence pattern that indicates a security system armed or disarmed command from a user interface device as well as a detected alarm signal of fire, burglary and carbon monoxide from a corresponding smoke, motion and carbon monoxide detector. These signals are transmitted from either the sensors or user interface means to the control panel and then, in turn, to the siren device.

Abstract: A system for recharging and testing a rechargeable battery having first and second terminals which includes a microprocessor having at least a first port; a charger coupled to the first port and a connector for attachment to one of the terminals of the associated battery; and a comparator coupled to the charger and to the first port. The comparator compares a voltage at the first terminal of the associated battery and a reference voltage and produces respective first and second outputs. The first output is produced when the voltage at the first terminal is below a first predetermined value and the second output is produced when the voltage at the first terminal is above a second predetermined value. The charger charges the battery in response to the first output and not charging the battery in response to the second output.

Abstract: Method and apparatus for remotely connecting an offshore structure to an underwater pipeline using a remotely operated vehicle (ROV). The structure has a bell-mouthed bending guide at its base through which a winch line from the surface passes and is temporarily looped back and attached to an accessible place on the structure. Using the ROV and a surface tended messenger line the pull-in line is attached to a terminal assembly at the end of flexible pipe attached to the pipeline. The terminal assembly is pulled in horizontally to the guide, arcuately through the guide and then from the guide in general vertical alignment with a pipe end receiver assembly on the structure above the bending guide. At a location near the receiver assembly a towing head is removed from the terminal assembly and a second pull-in line is attached to the terminal assembly. The two pull-in lines are attached to opposite sides of the terminal for balanced pulling of the terminal assembly to connection with the receiver assembly.
