Title: Method of and switching facility for switching between two data streams without data loss
Inventor: WILHELM MICHAEL
IPC: H04L12/28
Filed: 1999-10-04
Abstract: To be able to switch between two data streams (d1, d2) that are identical or similar in content without introducing errors, particularly without data losses, the two data streams are compared for time offset, and if a time offset between the two data streams (d1, d2) has been compensated for, switching is effected from the compared first data stream (d1) to the compared second data stream (d2). The switching facility for accomplishing this comprises a comparator circuit for comparing the two data streams (d1, d2) for time offset, a compensator (4) to compensate for the time offset, and a switching device (S) for switching from the compared first data stream (d1) to the compared second data stream (d2) if the time offset has been compensated for.

Title: Combined parallel adaptive equalizer/echo canceller
Inventor: RAO SAILESH KRISHNA
IPC: H04L25/03
Filed: 1998-03-25
Abstract: A combined, parallel adaptive equalizer/echo canceller is disclosed. The equalizer/canceller receives at least one input signal which is split into n taps. The n taps are multiplied by corresponding n tap coefficients to produce n tap output signals. The n tap output signals are then processed through an additive pipeline to produce a filter output signal. The additive pipeline provides low latency by processing the nth most recent tap output signal n clock cycles from the filter output signal. The combined FIR filter structure is made fully adaptive using delayed LMS coefficient adaptation. Tap coefficients are updated using an error signal and delayed versions of the input signal. The error signal is a product of a calculated error and a negative adaptation factor. The delay is equal to a sum of n+1 cycles.

Abstract: The present invention provides a reconfigurable modular drive joint that can be used as the basis for building and configuring robotic and automated systems as an interconnected network of individual nodes, with each node representing a single modular joint. Each modular joint can be quickly set up in either a roll, pitch or yaw configuration. A large number of different robot structures can be built using a small number of the modular joints in any of these three configurations.  The modules are equipped with quick-connect mechanisms so that a new robot structure can be assembled in a few minutes. A robot or other automated system assembled from such modular joints is a true reconfigurable and modular system. The control system is decentralized. Each modular joint is provided with its own built-in control system and electronics. The modular joints each include a motor and associated sensors. An embedded control system including a power amplifier for the motor, a sensor interface, microprocessor, and communication circuitry are provided. The only external connections to each module are a communication bus between the modules and the host computer and a power supply bus.

Title: System and method of mobile station presence verification in a multiple-hyperband cellular telecommunications network
Inventor: OLVERA-HERNANDEZ ULISES
IPC: H04W36/08
Filed: 1999-01-19
Abstract: A system and method of performing presence verification for a multiple-hyperband mobile station (29) in a candidate cell for handoff in a multiple-hyperband cellular telecommunications network. The network includes a mobile switching center (MSC) (10) and a plurality of cells, each of which operates in one of a plurality of hyperbands. A single verification device such as a location and verification module (LVM) (37) is installed in each cell (13) in the cellular network, each LVM operating in the cell's allocated hyperband.  When a verification request is generated, the system determines whether the candidate cell has an LVM (37) in the hyperband in which the mobile station (29) is operating. If not, the system determines whether the candidate cell has an overlaid cell (14), and whether the overlaid cell has an LVM (38) operating in the hyperband in which the mobile station is operating. If so, the system then utilizes the LVM of the overlaid cell to verify the presence of the mobile station in the candidate cell. The verification results are then reported to the MSC.

Title: Optical recording medium, device and method for recording optical recording medium, and device and method for reproducing optical recorded medium
Inventor: SAKO YOICHIRO
IPC: G11B7/09
Filed: 1999-12-07
Abstract: Twenty-bit audio data is separated into first data of high-order 16 bits and second data of low-order 4 bits. EFM-modulated data is created from the first data. A laser beam is turned on/off according to the logical level of channel data that is created by NRZI-modulating a serial data string. Consequently, the first data is recorded in the same way as in a compact disk. According to the second data, each pit is controlled to have displacement in a horizontal direction with respect to the track center, allowing a displaced pit to be formed. When data is thus recorded depending on the pit displacement, the high frequency component of a tracking error signal is changed during reproduction. Thus the second data can be extracted from the tracking error signal.

Abstract: The system for automatically routing calls to call center agents provides the call center administrator with an automatic agent assignment paradigm which functions to automatically increase the efficiency of assigning multiple skill agents to contacts. The presence of an agent surplus condition provides the present system with a plurality of choices in the assignment of the agent to process a presently received contact. Since the agents who staff the call center include multiple skill agents, the system must make a determination of not only which of the available agents is the best equipped to handle the present contact, but also how that assignment statistically effects the efficiency of successive assignments of agents to contacts next received, based upon the past performance of the agents and the call center. Since the traffic load presented to the call center tends to be highly variable and of content that is difficult to predict, the present system provides several automatic agent assignment paradigms that each have a statistically different impact on the performance of the call center, based upon the quality and quantity of the incoming calls.
