Abstract: A modular electronic deadbolt includes a bolt module having a first housing defining a first longitudinal axis, a motor disposed in the first housing, and a deadbolt configured to be linearly moveable in relation to the first housing along the first longitudinal axis by the motor. The modular electronic deadbolt also includes a battery module configured to be operatively coupled to the bolt module. The battery module includes a second housing configured to receive a power source, and a face plate coupled to the second housing. The faceplate defines a second longitudinal axis and includes an extension that extends along the second longitudinal axis. The extension is configured to removably couple the bolt module to the battery module such that the first longitudinal axis is substantially orthogonal to the second longitudinal axis.

Abstract: An electronic deadbolt includes a face plate and a housing having a first end and an opposite second end. The first end is releasably coupled to the face plate, and the housing further includes a bolt compartment defining a bolt axis and a battery compartment defining a battery axis. The bolt axis is substantially parallel to and offset from the battery axis, and the bolt compartment is separated from the battery compartment proximate the second end of the housing. The electronic deadbolt further includes a bolt module disposed within the bolt compartment. The bolt module includes a motor and a deadbolt, and the deadbolt is configured to be selectively linearly extended from the face plate along the bolt axis.

Abstract: An electronic keeper includes a housing defining a battery chamber and an actuator chamber. An actuator is at least partially disposed within the actuator chamber. The actuator includes a strike and a magnet, and is pivotable between a first position and a second position relative to the housing. The actuator is also biased towards the first position. The electronic keeper also includes a senor disposed within the battery chamber. When a locking element is in contact with the strike, the actuator pivots from the first position towards the second position so that the magnet moves relative to the sensor.

Abstract: A lock actuator assembly includes an escutcheon defining a longitudinal axis. A rotatable drive disk is rotatably coupled to the escutcheon about a rotational axis. A slide arm is slidingly coupled to the escutcheon and operably coupled to the drive disk such that movement of the slide arm along the longitudinal axis rotates the drive disk about the rotational axis. Additionally, an electronic actuator is coupled to the escutcheon. The electronic actuator is configured to drive the slide arm along the longitudinal axis, and the drive disk is adapted to couple to a lock mechanism so as to shift the lock mechanism between a locked position and an unlocked position when the drive disk rotates about the rotational axis.

Abstract: An access system for a structure includes a control box mounted within a controlled access space of the structure and operatively coupled to a door panel operator that opens and closes a door panel of the structure for access to the controlled access space. The control box is configured to detect a presence of a security device relative to the control box, determine a position of the security device relative to the structure, and determine an authorization of the security device. The access system also includes a user interface mounted in an uncontrolled access space of the structure and coupled in communication with the control box. Upon actuation of the user interface, the control box operates the door panel operator when the security device is positioned proximate the control box, located in the uncontrolled access space of the structure, and authorized to operate the door panel.

Abstract: A piston for an internal combustion engine of the spark ignition type has cavities formed in the crown in a pattern to cover approximately 16 to 18 percent of the piston head surface area. The cavities are formed in a pattern wherein no cavity edge is closer than approximately ¼ inch to ½ inch of any adjacent cavity edge or to the perimeter of the piston head. The cavities are generally cylindrical wall structures having a bottom in the form of a cone tapered to a central point. The depth of the cavity is approximately 55 percent of the cavity diameter.
