Abstract: A method and system (100) establishes voice communications between a computer operator (102) and an agent (104) of a business over a computer network, such as the Internet (108). Using an operator computer (106), the computer operator (102) views advertisements of the business' products or services on the Internet (108) via customized home pages (200). When the operator (102) wishes to order a product or ask additional questions about a product, the operator (102) activates a “call me” button (210). A return call screen (300) is then presented to the operator (102) with areas to insert a name (302), a telephone number (304) and a time to call (306). This information is packetized in a call request which is transmitted over the Internet (108) to a telephone switching system (112) associated with the business. The telephone switching system (112) subsequently dials the telephone number (304) at the time to call (306).

Abstract: An automatic call distributor 100 and method for selectively connecting incoming telephone calls from telephonic units 102 to a plurality of available agents located at agent telephonic units 308 is provided. The automatic call distributor 100 includes a central processing unit 302 which controls a multiport switch 300 to interconnect the incoming telephone calls and the agent telephonic units 308. Each agent is assigned one or more agent-skill indicators indicative of the agent's skills.

Skill groups 110a, 110b and 110n are formed from available agents having a common agent-skill indicator. Within the skill groups, the agents are arranged by decreasing proficiency rating. Agents with identical proficiency ratings are further arranged by the amount of time each agent has been available to accept an incoming telephone call.

Abstract: An O-plate compensator comprising an organic liquid crystal polymer, and methods for fabricating the same, are disclosed. The compensator is a uniaxial birefringent thin film with its extraordinary axis oriented obliquely with respect to the surface of the film. (It is noted that the birefringent thin film could be weakly biaxial.) The oblique orientation of the liquid crystal director, which is parallel to the films extraordinary axis, is achieved by casting an organic thin film onto a surface specially prepared for a orienting liquid crystals, such as obliquely deposited SiO, mechanically rubbed alignment agents. The film can either be cast from a solution of the liquid crystal polymer or from a reactive liquid crystal monomer having a nematic phase. Any solvent that may be used during the fabrication process is evaporated off and the organic thin film is held at a temperature in its nematic phase. If a reactive monomer is used, the film is then photopolymerized.

The call-skill indicator is then matched to a common agent-skill indicator of one of the skill groups. The telephone call is routed to the available agent in the matched skill group having been available the longest time.

Abstract: A video communications system 100, a video switching system 108 and method are provided for establishing video communications with a video communications device 104 utilizing the agent selection and reporting features of an automatic call distributor (ACD) 102. The ACD 102 receives an initial request from the video communications device 104 and rejects the initial request. A computer system 112 detects the initial request and acquires destination information in the initial request identifying the video communications device 104. The computer system 112 sends a simulated call to the ACD 102 requesting an agent for video communications. The ACD 102 selects an agent and notifies the computer system 112 which agent is selected. The computer system 112 then instructs an agent terminal 110 associated with the selected agent to establish video communications with the video communications device 104. The ACD 102 generates reports relating to the video communications.

Abstract: A system and method of detecting and correcting for cycle slip in a GPS attitude determination system is presented. The method employs several techniques for detecting and correcting for faults in high integrity carrier phase-related applications. A delta single difference is used as a primary measurement residual in detecting cycle slip. The delta single difference represents the difference in phase of a carrier signal of a GPS satellite at two receiving antennas over two points in time. This delta single difference is compared to a detection failure threshold computed based on certain high integrity needs. Satellites showing a failure are excluded. In addition, satellites that fail a detectability test, indicating the inability to detect a fault, are pre-excluded from attitude solution computation.

Abstract: A digital subscriber line communication system does not require the use of a plain old telephone service (POTS) splitter in the resident's home. Digital signal processing techniques are utilized to adapt to varying subscriber line conditions due to POTS telephone equipment. The digital signal processing techniques eliminate the need for a splitter by reducing susceptibility to distortion due to varying subscriber line characteristics. The digital subscriber line modem utilizes quadrature amplitude modulated (QAM) signals and frequency division multiplexing. The digital subscriber line modem includes a control circuit which includes a rapid retrain circuit. The rapid retrain circuit can retrain the digital subscriber line modem in less than 0.5 seconds.

The signal detector 100 comprises a sample detector 108 which detects digital code samples for past sample periods and the instant sample period. Past digital code samples are stored in a sample storage 114. Past digital code samples and the instant digital code sample are compared by a comparator 112. If the samples are equal, the signal path 102 is idle. If the samples are unequal, the signal path 102 is in use. It is contemplated that the past digital code sample substantially immediately preceding the instant digital code sample will be compared to the instant digital code sample.

Abstract: A switchable biasing device for an analog CMOS differential amplifier provides a supply bias current and a corresponding input bias voltage to achieve reliable performance with various power supply voltages. The bias device may include a control element having states corresponding to power supply voltages. The control element controls a supply bias circuit for supplying bias current to a differential amplifier at a level corresponding to the power supply voltage represented by a control signal from the control element. The bias current is made lower for a low power supply voltage to ensure that current source stage elements of the differential amplifier operate within their saturation region, and higher for a high power supply voltage to ensure sufficient current to maintain slew rates. The control element further controls an input bias circuit for providing a dc bias voltage at inputs of the differential amplifier at levels corresponding to the power supply voltage represented by the control signal.
