Title: Quantum cryptography device and method
Inventor: HUTTNER BRUNO
IPC: H04B10/70
Filed: 1997-08-15
Abstract: System and method of communicating a key between two stations (1, 2) using an interferometric system for quantum cryptography. The method comprises the step of sending at least two light pulses over a quantum channel (3) and detecting the interference created by said pulses in one station (Bob). The interfering pulses run over the same arms of said interferometer, but in another sequence, so that they are delayed when they run over said quantum channel. The pulses are reflected by at least Faraday mirrors (14, 16, 22) at the ends of said quantum channel, so as to cancel polarization effects. Advantages: the system does not need alignment or balancing between the arms of the interferometers. Plug and play stations (1, 2).

IPC: G01L5/00
Filed: 1997-11-07
Abstract: An apparatus (20) for press operation data acquisition comprises a tie rod (45a) for bearing a load during a press cycle. The rod (45a) has a load bearing portion (76) and a non-load bearing portion (78). An elongated, axially extending bore (75) is formed in one end (62) of the rod (45a) such that the bore (75) extends from the non-load bearing portion (78) into the load bearing portion (76). A linear variable differential transformer (LVDT) (24) includes a core portion (114) movably disposed relative to a coil portion (118), such that magnetic flux generated by current impression on the coil portion (118) is influenced by a position of the core portion (114) relative thereto. The core portion (114) is secured to a shaft (80). The shaft (80) is adapted for axial movement within the bore (75) in response to deformation of the rod (45a) during press operation. The coil portion (118) is adapted to receive an electric signal current from an associated electric source. The magnetic flux induced by operation of the associated press is regularly sensed by monitoring of the electric signal in a sensing coil portion (120). A  position signal is periodically generated (126) that is representative of a relative position of the core portion (114) to the coil portion (118) in accordance with sensed magnetic flux. The apparatus is adapted for automatically calibrating the position signal (304, 306) to a base level prior to initiating a press cycle of the associated press. A press deflection signal is generated (320, 322) in accordance with the position signal.

Title: Predictive bursty real-time traffic control for telecommunications switching systems
Inventor: RUIZ JOSE GUADALUPE
IPC: H04Q3/545
Filed: 1999-08-09
Abstract: A traffic control system (and associated method) according to the present invention includes a feedback control mechanism in which the controlled variable is processor occupancy, the controlling variable is the amount of resources necessary to satisfy the operational requirements of the switching system, and the set point is the average expected load based on a Poisson arrival rate. Current processor occupancy is compared, on an instantaneous basis against the set point to detenmine if it exceeds the average expected load. If so, the controlling variable is adjusted to allocate additional resources to process the offered traffic load. The process continues until the traffic burst expires. Additional resources may be obtained by eliminating or deferring non-essential work, and by allocating additional call registers, effectively accepting work in larger increments or batches. By instantly and proactively responding to traffic bursts, this traffic control system aids the switching system in weathering brief periods of high traffic, without actually reaching an overload condition and invoking overload controls. As a result, switching system capacity is increased, and other performance characteristics are improved.
