Abstract: An electronic lock with power failure control circuit includes a lock mechanism having a latchbolt movable between extended and a retracted positions and an electrically powered lock actuator to lock and unlock the latchbolt. The power failure control circuit includes a microcontroller and the lock is connected to a primary power source and an auxiliary power source, preferably supercapacitors and charger that can be turned on by the microcontroller and off when the charger signals a full charge. A power monitor circuit detects low voltage on the primary power supply and sets a power failure interrupt causing the microcontroller to execute power failure instructions that control the actuator so that the lock is placed into a desired locked or unlocked final state during the power failure. upon detection of the return of good power, the system resets the lock.

Abstract: An insulated siding member and a method of fabricating an insulating siding member is described. The siding member may include a siding panel, an insulation member and a backing layer. The siding panel may have a cavity that may serve as a molding receptacle to allow the insulating material to be molded directly into the cavity of the remainder of the siding panel. The cavity may also allow for the insulation layer to be applied directly to the panel, whereby there may be no need for an additional adhesive layer to attach the insulation member with the siding panel. Thus, the backing layer may be attached directly to the insulation member. The siding member may have a configuration that may also allow the siding member to be easily engaged with or be interlocked with another siding member to provide for better and more uniform insulation.
