Abstract: Methods and systems for optimal access of data are disclosed. A system for optimally updating data is described wherein a central database transmits a location table to a remote terminal having an access time variant (ATV) storage medium wherein a first set of data items is stored. The data on the ATV medium can be displayed visually upon a user's accessing a particular piece of data from the ATV medium. The user's data access habits are indexed on a location table by the central database where the location table is optimized and updated according to the number of accesses the user makes to particular data items. A second set of data is then transmitted to the remote terminal along with the updated location table and stored on the ATV database in optimized form, thereby reducing the access time to the second set of data on all the remote terminals since each particular user's individual habits govern the optimization process.

Abstract: A device for locking the brake of a vehicle and preventing its theft comprising: a base member for a placement on the floorboard of a vehicle beneath a brake pedal; a U-shaped housing extending downward and having a first arm attached to the base and having a second shorter arm defining a gap for receipt of a brake pedal shaft, said space between the first and second arms defining a slot for receiving the brake pedal shaft and permitting its full extension upward through said shaft; and locking means associated with the second arm for locking the underside of the pedal within the slot such that the brake pedal cannot be depressed.
