Abstract:
Systems and methods described in this application are directed to hatch lid actuation systems. Actuation systems of the inventive subject matter are configured to effect the opening and closing of lids that are hingedly coupled with an opening. An embodiment featuring a rotational actuator, e.g., a motor, as well as an embodiment featuring a linear actuator are described. Embodiments having rotational actuators can additionally feature a gearbox. Embodiments of the inventive subject matter can also include sensor packages that can determine various hatch lid conditions (e.g., whether a lid is open, closed, wet, etc.).
Abstract:
A lock assembly comprises a driving member, a drive assembly, and an engaging member. The drive assembly comprises a drive connector operatively connected to the driving member, a lead screw operatively connected to the drive connector, a carriage configured and arranged to move along the lead screw, and an elongate member operatively connected to the carriage. The driving member is configured and arranged to rotate the drive connector, and the drive connector is configured and arranged to rotate the lead screw. Rotation of the lead screw moves the carriage along the lead screw and the elongate member moves with the carriage between locked and unlocked positions. The engaging member is configured and arranged to selectively engage the elongate member in the locked position.
Abstract:
A system for providing securement of a plurality of secure portable encasements including one or more encasements each configured to engage, and subsequently disengage, inseparable interaction with a common docking unit; and one or more common docking units.
Abstract:
An illustrative access control system includes a locking assembly operable in locked and unlocked states, and a drive assembly operable to actuate the locking assembly. The drive assembly includes an electromechanical actuator, and energy storage device, and a control system. The electromechanical actuator is operable, upon receiving power, to transition the locking assembly between the locked state and the unlocked state. The energy storage device is electrically coupled to the electromechanical actuator, and configured to store electrical power from the power supply when the drive assembly is coupled to the power supply. The control system is configured to couple the drive assembly to the power supply in response to a first condition, and to thereafter transmit energy only from the energy storage device to power the electromechanical actuator, based at least in part upon a level of energy stored in the energy storage device.
Abstract:
Provided is a lid device which is compact, and can be installed in an efficient manner. The lid device (20) releasably locks a lid provided with a hinge (12) in a closed position. The lid device is provided with a push lifter that alternates between an extended state and a retracted state each time the lid is pushed, a motor (54) placed next to the push lifter, a lock member (18) and a transmission mechanism (60, 64) for transmitting the output of the motor. The push lifter and the motor are arranged such that a lengthwise direction of the push lifter and a lengthwise direction of the motor are perpendicular to each other, and such that the motor at least partly overlaps with the push lifter when seen from the lengthwise direction of the motor.

Abstract:
A door lock mounted to a door includes a latch head. A receiver includes a charging circuit and is mounted to the door. A battery provides electricity required for moving the latch head between a latching position and an unlatching position or providing electricity required for permitting or not permitting movement of the lead head from the latching position to the unlatching position. A transmitter includes a wireless transmitting circuit and is mounted to a door frame to which the door is pivotably mounted. The transmitter is connected to a power supply. When the door is in an open position, the receiver is not aligned with the transmitter. When the door is in a closed position, the receiver is aligned with the transmitter, the receiver receives radio wave from the transmitter, converts the radio wave into electricity, and stores the electricity in the battery.
Abstract:
An electric latch retraction device comprising a housing for receiving a plurality of internal components of the electric latch retraction device. An actuator mechanism is included in the housing, the actuator mechanism is adapted to impart linear movement on a latch, such that the latch is retracted towards the housing. A holding mechanism is also included in the housing, the holding mechanism holds the latch in a fully retracted position.
Abstract:
