Abstract: A digitally sampled spread spectrum signal is received, despread, and accumulated at a center frequency lower than the sampling rate and higher than zero.

Abstract: An operating system independent distributed self-contained dynamic logic system is disclosed. The dynamic logic system enables EO functionality in small edge routers or programmable switches which serve a small population of users instead of the rather large population typically served by a 5ESS or DSM100 central office switch. A disclosed method provides the capability for EO switch enhanced functionality that is programmable from a remote location The dynamic logic system may be implemented across several elements, including a subscriber database called a Service Control Point (SCP), a computer called a Service Management Point (SMP) for controlling and distributing programmable logic to implement EO features, and an Edge Switching Point (ESP) for interacting with a physical device (telephone/data endpoint). The dynamic logic system may be introduced at the “intercept” layer between the physical edge switching point device, typically a telephone interface, and a routing network.

Abstract: A transmitter to transmit data from an end-point includes a reference oscillator; a low pass filter coupled to the reference oscillator; a modulation filter to provide an over-sampled modulated signal; a synthesizer coupled to the low pass filter and the modulation filter; and a sine wave generator coupled to the synthesizer.

Abstract: A dynamic transaction network having multiple management stations, one or more terminals, and one or more databases is disclosed. The dynamic transaction network is capable of adding and removing network hosts (terminals, databases, and management stations) in real-time while continuing to service transaction requests. In addition, the dynamic transaction network is capable of transferring database fragments from a source database to a target database in real-time. In response to a transaction request from a caller, the terminal accesses information stored in a corresponding database via dynamic transportable logic. The dynamic transportable logic derives the location of relevant information in the database from input characteristic(s) of the transaction request.

Abstract: A Hall effect sensor or device may be used in a variety of embodiments, such as measuring current within an associated conductor by helping to measure flux density within a gap of a ferromagnetic power meter core, such as in a power meter. A high linearity interface for a Hall effect device is provided for minimizing offset effects without using complicated electronic circuits. Hall effect device is characterized by first and second opposing surfaces, first and second device inputs, and first and second device outputs. A substrate is layered adjacent to one of the first and second opposing surfaces of the Hall effect device and is electrically connected to an output pin of the Hall effect device to eliminate any effects caused by asymmetry of the voltage appearing in the channel relative to the substrate.

Abstract: A method and system for managing a large network of switching end-points to route calls by time of day and day of week over a packet switched network (ATM or Voice over IP). The preferred management mechanisms determine circuit and location availability and include means for removal and replacement of circuits from network-wide service, even in a private, packet-switched network. In an automatic call distribution environment, the method is an economical and efficient process for facilitating a caller's ability to access users in workgroups wherein the users utilize either wired or wireless communications tools. Users are chosen via a rule-based selection process including access to a database of users, caller-screened information, and circuit and location availability.

The arrangement generally includes at least two printed circuit boards housed in a casing structure. Various projections extend from the casing structure to effectively position and secure the printed circuit boards within an overall component assembly, Specific projections employed for positioning the circuit boards include tapered locator pins and respective mating holes as well as key projections that interconnect with slots located in selected circuit boards. Snaps project from casing components to securely constrain the circuit boards within the component assembly. Established orientation of various components and projections significantly facilitates the meter assembly process.

Abstract: “A Hall effect sensor or device may be used in a variety of embodiments, such as measuring current within an associated conductor by helping to measure flux density within a gap of a ferromagnetic power meter core, such as in a power meter. A high linearity interface for a Hall effect device is provided for minimizing offset effects without using complicated electronic circuits.

The substrate of the Hall effect device may be connected electrically to an output pin of the Hall device to eliminate any effects caused by asymmetry of the voltage appearing in the channel relative to the substrate. The net effect of the high linearity interface is to eliminate any adverse effects to linearity of the system, especially at low magnetic flux levels where the output voltage of the Hall device would be relatively small compared to the offset voltage levels involved.

Abstract: An integrated structure that offers improved casing for an electric utility meter is disclosed. The improved structure uses a minimum number of parts required for proper functionality of a meter casing, and excludes the use of screws, clips or other additional parts that make meter disassembly a tedious procedure. The meter casing generally includes a baseplate, at least two inner covers for housing and protecting electronic components for an electric utility meter, an outer cover, and pluralities of projections extending from the covers for interconnection of casing components and stabilization of the integrated casing structure. The various electronic components of the meter generally include electronic circuit boards and current transformers. The various projections enable snap-fit connections between the baseplate and an inner cover, between inner covers, and between inner covers and an outer cover.
