Abstract:
A lock includes a stationary key mass having a first key mass bore and a keyway, and a movable spring mass including a first spring mass bore. A first spring mass pin is mounted in the first spring mass bore, and a first key mass pin is mounted in the first key mass bore for reciprocation between a locked position immobilizing the spring mass and an unlocked position unconstraining motion in at least one direction. The unlocked position is a function of the presence of a matching key in the keyway. Multiple key mass and spring mass pins can be used, some or all of which can have stepped configurations, and corresponding single-bladed or multi- bladed keys, or multiple keys, can be used. The keys can be straight or curved in any of various planes, or they can be straight but flexible to match curved keyways. Curves can be unidirectional or compound. Relative motion between the key mass and spring mass can be in a plane or along straight line or circular.
Abstract:
A rotatable or pivotable door handle locking device is provided comprising first and second body portions. At least one of the portions includes receiving means for receiving a rotatable or pivotable door handle. At least one of the body portions includes one or more arms which are received by corresponding recesses on the other body portion. The body portions are capable of relative movement between a first position in which they are engaged via the arms and recesses, and a second position in which they are disengaged. The body portions and/or arms are arranged such that they substantially block or prevent rotation or pivotal movement of the handle when fitted thereto and moved to the engaged position.
Abstract:
A sending device generates a MAC frame to be transmitted over a wireless network. The MAC frame indicates a frame transmission type. A payload portion of the MAC frame is defined in accordance with a payload specification of a distributed asset management protocol corresponding to the indicated frame transmission type. The MAC frame is transmitted over the wireless network and received by a receiving device that is defined to recognize the MAC frame as the indicated frame transmission type. The receiving device is defined to process the payload portion of the MAC frame in accordance with the payload specification of the distributed asset management protocol corresponding to the indicated frame transmission type. Network discovery includes successively transmitting the MAC frame at a defined interval during a first period of time. Then, the MAC frame transmission is ceased for a second period of time. Then, transmission of the MAC frame resumes.

Abstract:
A locking mechanism (10) comprising a housing (16) and a shackle (14) having a first side (44) and a second side (46). The shackle (14) is slidable between a primary closed position in which the first and second sides (44 and 46) are each engaged with the housing (16) and a primary open position in which the first side (44) is engaged with the housing (16) and the second side (46) is free from the housing (16). A port (65) is provided in the housing (16) exposing a portion of the first side (44) of the shackle (14) in the primary closed position. Severing the shackle (14) through the port (65) allows the shackle (14) to move from the primary open position to a secondary open position, from which the shackle (14) can move back to a secondary closed position.
Abstract:
A lock mechanism for sealing a goods compartment has a housing (10) supporting a shackle (62) movable between open and closed positions to permit hoops on the ends of an elongate sealing member (44) to be connected thereto and then held thereby. The shackle (62) is retained in its closed position by a spying loaded push-button (32) and also by an auxiliary lock (64) including an electric actuator (71) controlled by a control unit (15). The housing (10) has a display device (17,18,19) to indicate the lacking condition and sealing of the mechanism and also has a proximity card reader adapted to read information from a presented smartcard, operation of the auxiliary lock (64) being controlled by presentation of an appropriate smartcard.
