Abstract: A lock assembly allows selective locking of a refuse container so that it cannot be manually opened by an unauthorized user, but can be opened automatically by a refuse collection truck when the container is to be emptied. The lock assembly has a locking bar that is attached to a control bar which is pivotally mounted to the refuse container. In one embodiment, the control bar is selectively connected to a spring such that when the container is to be locked, the control bar and locking bar are connected to the spring by a lock and in order to open the container the bias of the spring must be overcome. The spring is set such that this bias is easily overcome by engagement of the coupler of a refuse collection truck. When the lock is removed, the control bar is separated from the spring and the locking bar freely rotates. In another embodiment, the locking bar is connected to a spring bias control bar by articulated connecting members.

Abstract: The present doorlock closure secures existing doors having conventional doorknobs against entry by enveloping the doorknob with opposed cavity compartments of knob confining segments. Upper and lower housing segments are hinged together such that they may mount elements which form a cam-lever, segment interlocking assembly. The assembly includes a spring-loaded latch and lockable latch lever in the upper segment and a corresponding cam latch release in the lower segment. The housing segments themselves are hinged together for facile clamping upon the doorknob of a door, securing it against entry by persons having a passkey to the doorknob which retains a turnkey lock therein.
Abstract: A control system for a revolving door includes an ultrasonic sensor having multiple sensor heads. The door has a housing and multiple movable compartments formed by door wings. The sensors emit energy waves into the housing in bursts, then receive echoes from any objects, including people, in the compartments. The sensors are activated when the door is activated by an authorized user. A controller stores a binary "echo" or "no echo" signal in memory in response to an emitted energy wave. The system determines a maximum height of an object or person in a compartment, then measures the total amount of time that it detects something above a selected percentage of the maximum height. When this time reaches a predetermined amount, the system interprets that as "piggybacking" (two individuals in one compartment). The system also interprets signals that go above, drop below, and then rise above the selected percentage again as piggybacking.

Abstract: In order to improve the locking of a bicycle which is provided with a bicycle lock with a built-in cable- or chain-lock (12), a lock according to the invention is configured in such a manner that the cable-lock (12, 14) can be locked only providing that the locking ring (6) is locked, and vice versa. The lock hereby affords better protection, the reason being that when the lock according to the invention is used, then both the lock's normal locking ring (6) as well as the cable-lock (12) have to be broken open. This is achieved by preventing the locking pawl (4, 33) from entering into a locking engagement with the locking groove (15) in the locking piece (14) unless the locking pawl (4, 30) is engaged with the locking groove (10) in the locking ring (6), and vice versa.
