Abstract: Extension assemblies for connection to one or both ends of a safety barrier to increase its width include top and bottom elements, each having a horizontal channel therethrough, a vertical connection element extending therebetween, and assembly elements which extend through the respective horizontal channels and into aligned holes in the barrier to resist lateral forces.

Abstract: An electronic radiotelephone comprising a first housing, a second housing, and an inner housing having retaining means for retaining to the inner housing the electronic components of the radiotelephone; and first releasable attaching means for releasable attaching the first housing to the inner housing, wherein the first housing, when attached to the inner housing, is presented towards a user during operation of the radiotelephone; and second releasably attaching means for releasable attaching the second housing to the inner housing, wherein the second housing, when attached to the inner housing, faces away from the user during operation of the radiotelephone.

Abstract: Techniques for allowing an application designed to store data for one group of users to store data for a plurality of groups of users include modifying the application to cause the application to indicate a routine to a database server that stores data for the application in a database. The routine provides modifications to queries of the database, which limit access based on the groups to which belong users that cause the queries to be submitted. In response to receiving a query involving the database and caused by a particular user, the database server locates the routine, and, prior to executing the query, modifies the query. Modifying the query includes invoking the routine. The modification to the query thereby limits access of the particular user to data that is associated with the group of users to which the particular user belongs.

Abstract: A method and apparatus are provided for storing data of multiple enterprises in a set of database objects in a database system and allowing multiple enterprises to interact with the database system as if those database objects contained only their data. According to an aspect of the present invention, a database command issued against a database object by a user is modified by adding predicates that limit access to data associated with the enterprise in which the user has data access. The predicates may specify conditions based on a column in the database object that identifies the enterprise. When a user issues a database command to add data to the database object, the column is populated in a manner transparent to the user. The data in the database object that is associated with a particular enterprise is stored in a separate tablespace.

Abstract: Am apparatus includes a pair of frame members adapted for mounting to opposing surfaces of a passagaway. A door is mounted to at least one of the frame members for movement between a closed position, in which the door and frame members substantially traverse the passagaway, and an open position, in which a portion of the passageway is free of the door and frame members, the portion being large enough to permit passage of an adult therethrough. A lock is coupled to at least one of the frame members and adapted to retain the door in the closed position, the lock including an actuator adapted to release the lock to permit movement of the door from the closed position toward the open position upon application to the actuator of a force of at least a predetermined weight of a child.
