Title: Method of determining a temporary subscriber number (tmsi) in a subscriber data base
Inventor: PFUNDSTEIN MATTHIAS
IPC: H04Q7/20
Filed: 1992-06-03
Granted: 1999-09-28
Abstract: Subscriber data bases with large subscriber-data fluctuations require special strategies to ensure optimum utilization of the available storage space while keeping access times as short as possible. In addition, subscriber anonymity is to be ensured. A method is provided for assigning a memory location to each subscriber via a temporary subscriber number (4-byte TMSI).      The invention proposes an internal structure for the TMSI which consists of several logically independent elements which, on the one hand, permit as large an addressing range as possibly and, on the other hand, preclude any confusion of data records or any identification of the subscriber. In addition, the TMSI is constantly changed. With a 32-bit TMSI, up to 10 6 subscribers can be unambiguously addressed.

Title: Method and apparatus for the computer-controlled manufacture of three-dimensional objects from computer data
Inventor: PENN STEVEN M
IPC: B29C39/12
Filed: 1993-05-31
Granted: 2002-05-21
Abstract: A method and process for computer-controlled manufacture of three-dimensional objects involves dispensing a layer of a first material, such as a liquid, insoluble material onto a platform at predetermined locations corresponding to a cross-section of the object, which then hardens. A second medium, preferably water soluble, is then sprayed onto this layer to thereby encapsulate the hardened insoluble media. The uppermost surface of this encapsulant is planarized, if necessary, for example by way of a mill cutter, knife, roller or thermal bar, thus removing a portion of the encapsulant to expose the underlying insoluble material for new pattern deposition. The dispensing of the first and second materials, and the planarization, may be performed in a single pass by an integrated printhead. After the resulting planing residue is removed, another layer of liquid, insoluble medium is dispensed onto the planed surface. These steps are repeated, until the desired three-dimensional object, surrounded by a mold, is completed. At this point, the object is either heated or immersed in a solvent, thereby dissolving the mold and leaving the three-dimensional object intact; alternatively, the second material may remain in place to form a composite structure such as a printed circuit board. A method is also disclosed which converts a CAD data base representing a solid object into one representing a filled shell, reducing the amount of object material required.

Title: Vehicle axle alignment instrument and method
Inventor: SIMS JOHN DWIGHT
IPC: G01B5/255
Filed: 1993-01-07
Granted: 1996-08-20
Abstract: Axle alignment for a tractor-trailer vehicle combination is important for tire wear, fuel economy and driver fatigue. Misalignment occurs when the tractor thrust line vectors (one perpendicular to each drive axle) has a skew angle with re-spect to a longitudinal reference axis of the tractor. In addi-tion, the tandem axles of a dual axle combination must be par-allel to minimize scrubbing between the tires and the roadway. The same problems exist when the trailer drag line vectors (one perpendicular to each trailer axle) are not aligned with a longitudinal reference, and the dual axles are not parallel, due to axle misalignment. The instrument and method of this in-vention are compounds of an alignment system for making accurate alignment adjustments to the vehicle. The instrument is required to establish location points on the reference surface supporting the vehicle. A computer uses distances between lo-cation points to determine the relative position between axles and displays axle geometry on a monitor. Adjustments in the axle positions are provided based for the type of vehicle su-spension system.
