A system and method for a door system is disclosed. The system produces an inductive power transfer signal and modulates the inductive power transfer signal. The system also encodes data within the modulated inductive power transfer signal and transmits the signal at a door frame of a door. At the door, the system receives the modulated inductive power transfer signal and extracts data from the received signal, and transduces the received signal into a door power signal. The system also supports secure data transfer by encrypting the encoded data at the door frame and decrypting the extracted data at the door. As a result, the modulated inductive power transfer signal between the door frame and the door provides a secure wireless data transfer channel for configuring components at the door and/or displaying data at the door, while also providing power to components at the door.

A vehicle storage assembly of the vehicle is provided. The vehicle storage assembly if the vehicle includes a storage compartment comprising an opening to permit access to the compartment, a door proximate the opening and movable between an open position and a closed position, a latching mechanism comprising a residual magnet for latching a door in the closed position in a first magnetic state and for releasing the door to open to the open position in a second magnetic state, and a proximity switch for activating the latching mechanism to allow the door to move to the open position.

A door position sensor of an electromagnetic door lock. The electromagnetic lock also includes an electromagnet and a strike plate. The electromagnet is secured to the door frame and the strike plate is movably mounted to the door so that a controlled amount of door movement in the opening direction is permitted while the strike plate remains in contact with an energized electromagnet. The door position sensor may comprise a sensor in or on the electromagnet and a permanent magnet mounted to the door and disposed in proximity to the sensor when the door is in a closed position. The sensor may be a reed switch or a Hall Effect sensor. The permanent magnet and strike plate may be mounted to the door by a mounting tray. The mounting tray may include indicia to aid in providing a proper alignment of the strike plate to the door and electromagnet.

An effects control module for a musical instrument has a housing and a battery enclosure assembly rotatably coupled to the housing. The battery enclosure assembly includes a door with a magnetic plate attractive to a surface of the housing to enable final closure of the battery enclosure assembly with respect to the housing absent external force. No external human force is needed to enable and complete final closure of the battery enclosure assembly with respect to the housing after the critical magnetic position of the door. The battery enclosure assembly is disposed on a first side surface of the housing with a battery area and latch configured to contain a battery. A material is disposed on the door to soften the closure. A second side surface of the housing includes a paramagnetic material to provide substantially no magnetic influence from the second side surface of the housing.

An electromechanical biasing member for moving a closure panel between an open and a closed position relative to a motor vehicle body is provided. The electromechanical biasing member includes a housing having an inner cavity for housing an electric motor having a motor shaft and a rotary output member rotatable relative to the housing. An extension member within the housing and engageable with the rotary output member moves the closure panel between the open and closed positions in response to driving the electric motor. Also provided is a control unit positioned within the inner cavity and configured to drive the electric motor, the control unit including at least one controller board juxtaposed to the electric motor, and a plurality of control components mounted to the at least one controller board and configured to supply a drive signal to the electric motor and receive signals representative of operation of the electric motor.

A door lock and an electrical appliance using the door lock. The door lock comprises: a switch housing; a pen core-like mechanism disposed in the switch housing; a control needle (state means) passing out of the pen core-like mechanism; and a manual unlocking pull rod mechanism. The manual unlocking pull rod mechanism is capable of moving towards the control needle and coming into contact therewith. The position of the control needle (state means) indicates the switch state of the door lock, such that when the door lock is in an unlocked position, further pulling of the manual unlocking pull rod mechanism has no effect on the door lock switch mechanism.

A dual-contact electro-permanent magnet (EPM) assembly of an information handling system may comprise a plurality of high-coercivity magnets situated on opposite ends of a low-coercivity magnet, a first EPM magnetic contact disposed between a first of the plurality of high-coercivity magnets and the low-coercivity magnet, and a second EPM magnetic contact disposed between a second of the plurality of high-coercivity magnets and the low-coercivity magnet. The low-coercivity magnet polarity may correlate to a direction of current pulse applied to an electrically conductive wire coiled around the low-coercivity magnet, and dependent upon the low-coercivity magnet polarity, the first EPM magnetic contact is capable of operating in an attractive magnetic state to attract a ferromagnetic contact of a peripheral device while the second EPM magnetic contact is magnetically neutral with respect to the ferromagnetic contact.

A magnetic lock includes a housing, an electromagnetic body, a positioning member, and at least one clamp. The electromagnetic body can be received in a receiving space of the housing. The positioning member has a lateral side that is to abut against an outer lateral side of the housing. After the corresponding lateral sides of the positioning member and the housing are brought into abutment against each other, the clamp can be installed to clamp together an end edge of the positioning member and the adjacent end edge of the housing, and thereby fix the positioning member and the housing together. When installing elements between the housing and the positioning member break or are detached after long-term use, the clamp produces an additional or auxiliary fixing effect to ensure the safety of use of the magnetic lock.

A magnetic lock structure with a large anti-pulling area includes a housing and an electromagnetic body received in a receiving space of the housing. The inner wall of the housing is provided with at least one first sliding portion. The outer wall of the electromagnetic body is provided with at least one second sliding portion. Once the electromagnetic body is pushed into the receiving space through an end of the housing, the second sliding portion abuts against the first sliding portion slidably to create a relatively large area of contact between the housing and the electromagnetic body. When the magnetic lock structure is in operation, the pulling force acting on the housing through the electromagnetic body is distributed evenly along the sliding portions to prevent deformation of the housing and prolong the service life of the magnetic lock structure.

A stand-alone, single-layer, auxiliary ballistic security barrier system configured to be installed over existing doors. The ballistic security barrier system provides protection against an active shooter with weapons, including handguns and high-powered rifles. The ballistic security barrier system includes a frame fixed to a wall with an anchor system and having structural tubing, mounting angle, and a locking system located inside the structural tubing. Further, the system includes a barrier pivotably attached to the frame and made out of material suitable to withstand impact from a high velocity rifle. The barrier is held in a first stowed position by a release apparatus, and in a second closed position by a lock.
