Title: Process and device for determining the characteristics of a motor vehicle's built-in shock absorbers
Inventor: LANGLECHNER RICHARD
IPC: G01M17/04
Filed: 1995-08-17
Granted: 2004-10-26
Abstract: A process is proposed for determining the characteristics of a motor vehicle's built-in shock absorbers. The vehicle is driven onto a ramp support which is then quickly removed, causing the vehicle to drop onto a base whose distance below the ramp support corresponds to the residual rebound clearance associated with the particular vehicle design; the changes in the so-called wheel contact force when the car hits the base are measured. The process is characterized by the fact that the vibration characteristics of the body and one wheel at a time ate measured, the measurement results, together with the measured values of wheel contact force, are fed into the known differential equations governing damped oscillations, and the characteristic data for the vehicle structure, namely, the body- and heel masses, spring stiffness and damping constants, are calculated.

Patent CA-2196243-C (CA)
Inventor: DIEPOLDER WOLFGANG
IPC: F01D21/04
Filed: 1997-01-29
Granted: 2005-07-26
Abstract: The invention relates to a bearing arrangement for rotors 1 of jet engines with a bearing 4, which is mounted on a rotor carrier 7 via a bearing carrier 5.      In the event of failure, for example if the blade of a compressor rotor breaks, damage to or destruction of the rotor carrier 7 or of the housing should be prevented by the fact that a breaking piece 8 breaking under a defined load is arranged concentrically between the rotor carrier 7 and the bearing carrier 5. In this way the transfer of extreme radial loads to the rotor carrier 7 or to the rotor housing enclosing it is largely avoided, provided that the rotating member 1 has not yet come to a standstill. The bearing arrangement in accordance with the invention is particularly of interest for turbo jet engines for aeroplanes, where for example, in the case of a damage of a fan-rotor blade, the effect of a destructive force of a rotor running at high speed on neighbouring housing areas can be reduced.

Title: Cryptographic key recovery system
Inventor: JOHNSON DONALD B
IPC: H04L9/10
Filed: 1997-02-05
Granted: 2002-12-10
Abstract: A cryptographic key recovery system for generating a cryptographic key for use by a pair of communicating parties while simultaneously providing for its recovery using one or more key recover agents. A plurality of m-bit shared key parts (P, Q) are generated which are shared with respective key recovery agents, while an n-bit nonshared key part (R) is generated that is not shared with any key recovery agent. The shared key parts (P, Q) are combined to generate an m-bit value which is concatenated with the nonshared key part (R) to generate an (m + n)-bit value from which an encryption key is generated. The cryptographic system has the effective work factor of an n-bit key to all of the key recovery agents acting in concert, but has the effective work factor of an (m + n)-bit to any other combination of third parties. The quantity n is selected to make authorized key recovery feasible, but not so trivial as to permit routine decryption of intercepted communications, while the quantity m is selected to make decryption by unauthorized third parties infeasible. Means are provided for verifying that the shared key parts have been shared with the key recovery agents before permitting encrypted communications using the thus generated key.

Title: Hierarchical remediation of service levels for transaction classes which are independent of the organization of resource skills
Inventor: CLIPPINGER JOYCE A
IPC: H04L29/08
Filed: 2000-02-08
Granted: 2005-08-02
Abstract: Hierarchical remediation on the unmet service needs associated with work items queued in a work processing facility is used in order to maximize the achievement of service level goals. A hierarchical remediator and corresponding hierarchical remediation method may each be employed in a work distributor or an automatic call distributor ("ACD"). The hierarchical remediator determines which work item among pending work items of different types will be distributed to an available server. The hierarchical remediator and its corresponding hierarchical remediation method ensure that more important jeopardized service levels receive greater remedial compensation than the less important ones. The hierarchy of distinct service classes associated with jeopardized service levels may comprise one input to the hierarchical remediator. The hierarchical remediator may also consider a skill preference profile for the available server as another input. The hierarchical remediator generates a composite preference value for each alternate work item from among the work items queued in the work processing facility. The hierarchical remediator selects which work item to assign to the available server by identifying the work item having the highest composite preference value. The hierarchical remediator and the corresponding hierarchical remediation method may be directed to apply one of a variety of user-supplied functions in order to complete the calculations associated with the composite preference values.
