Title: Object verification apparatus and method
IPC: G06K19/08
Filed: 1988-01-15
Abstract: Apparatus and methods of verifying objects utilize an inherent randomly varying and detectable characteristic of a recordable magnetic region affixed to the object. Detectability of the randomly varying magnetic characteristic can be enhanced by recording a selected electrical signal thereon. Digital and analog signals may be used. Both saturation and nonsaturation forms of recording can be used. A verification apparatus senses the enhanced randomly varying magnetic characteristic and compares it to a prestored representative profile previously created. Correspondence between the prestored profile and the currently read characteristic indicates an authentic object. Other objects can be rejected.

Title: Device for moving an object, such as a goal, from one position to another
IPC: A63B63/00
Filed: 1989-03-24
Abstract: It is known to link handball goals (1) to extension arms which, in turn, are linked to a gymnasium wall so that, in conjunction with a cable drive acting on the goal frame, the handball goal (1) can be folded against the wall and, in this case, is situated at a height depending on the length of the extension arms. If the respective gymnasium is also used for football, the football goals (2) have to be set up and dismantled manually. By means of the device according to the invention, football goals (2) are linked via extension arms to receiving rails (14) which, in turn, are guided vertically in a slidable manner in guide rails (13) on the gymnasium wall. The football goal (2) can thus be stored at a height on the wall which allows the simultaneous storage of the handball goal (1). Both the handball goal (1) and the football goal (2) can be moved by means of special cable drives between a lower position, set up on the gymnasium floor, and an upper position situated on the wall. <IMAGE>

IPC: H04Q3/545
Filed: 1989-10-18
Abstract: In a distributed system, such as a PBX, which uses a database for its 
operation, a master copy (22) of the database having a first format is stored at a 
central node (10) and cache copies (32) of database portions (24) but having a 
different format are stored at peripheral nodes (11-12). A change to the database 
is made to the master copy, is recorded in a change table (26) corresponding to 
the affected database portion, and is sent to affected peripheral nodes. At 
initialization, a boot copy (25) is made of each database portion by translating the 
database portion from the master database format to the cache copy format. 
Periodically thereafter, each boot copy is replaced with a new boot copy that 
reflects changes presently recorded in the corresponding change table. When the 
new boot copy is generated, the present change table contents are erased. When a 
peripheral node calls for a new cache copy (e.g., upon reboot), it is sent the 
corresponding boot copy and any changes presently recorded in the corresponding 
change table.
