Abstract: A Mobile Switching Center (MSC) includes a cellular modem pool that comprises a number of pairs of modems in which the data terminal equipment (DTE) ports of each modem pair are cross-connected in a "back-to-back" fashion. This allows the two modems of each pair to interchange data via their DTE ports and thereby isolate that portion of the cellular fax call over the cellular communications channel from that portion of the cellular fax call through the public-switched telephone network (PSTN). Fax information is transmitted over both the PSTN-portion of the cellular fax call and the cellular portion of the cellular fax call using standard fax modulation techniques. The cellular-side modem of each modem pair is adapted to recover fax handshaking and data signaling from the received--fax modulated--signal and translate the recovered fax information into "AT-type commands" for application to the corresponding PSTN-side modem of the modem pair.

Abstract: A method and apparatus for actively simulating an apparent termination input impedance to a current driven data communication equipment (DCE) device is disclosed. The DCE device utilizes several components to implement the apparent termination impedance. A first component is a current driver for providing a source of current within the DCE device. The current source is configured to actively drive an input-output signal line within a communication link. The current driven DCE also includes a mechanism for sensing an input-output signal line voltage, a mechanism for converting the sensed voltage to a feed back current and an active termination for simulating an apparent termination impedance. The converting mechanism is coupled to a summation node which sums current provided from the current driver and current from the converting mechanism to force the desired termination impedance in the DCE device, whilst performing DCE current drive function.

Abstract: A rob bit compensation system improves the accuracy of digital signals received from and transmitted to a digital network, such as a telephone network, that employs rob bit signaling (RBS) wherein the network periodically robs a bit for its own use. The system can be employed within a digital modem or a coder/decoder (codec), each of which is interconnected with the digital network that periodically robs a bit every nth frame, where n is, for example, 6 or 24. The system can be implemented in association with the receive subsystem of the digital modem or in the communications paths within the codec associated with receiving data from the digital network. The system includes a compensation control utilized to detect when a least significant bit (LSB) of a particular frame of data consistently exhibits a certain logic state, either a mark (logical 1) or a space (logical 0). When an LSB of a particular frame does consistently exhibit the certain logic state, then the particular frame is considered an RBS frame.

Abstract: A method and system for determining a mass and energy balance for a glass furnace proceeds through a furnace model and calculates a number of parameters for the flows within each segment of the furnace. The mass flow rate, enthalpy, and enthalpy flow rate of each mass flow entering a segment is found and then the enthalpy and temperature of the unreacted mixture is determined. Based on an assumption that the flows entering a segment combust completely and instantaneously, the enthalpy, enthalpy flow rate, mass flow, composition, and temperature of a reacted flow exiting the segment is determined. If the furnace implements reburning, then the mass flows for the furnace are adjusted. Also, the mass and energy for each flow can be determined if the furnace has a regenerator, a recuperator, or a reburning system. Further, the mass and energy for each flow can be determined for a wide range of furnace types.

Abstract: The present invention provides a packet-based telemedicine system for communicating video, voice and medical data between a central monitoring station and a patient monitoring station which is remotely-located with respect to the central monitoring station. The patient monitoring station obtains digital video, voice and medical measurement data from a patient and encapsulates the data in packets and sends the packets over a network to the central monitoring station. Since the information is encapsulated in packets, the information can be sent over multiple types or combinations of network architectures, including a Community access Television (CATV) network, the Public Switched Telephone Network (PSTN), the Integrated Services Digital Network (ISDN), the Internet, a local area network (LAN), a wide are network (WAN), over a wireless communications network, or over an asynchronous transfer mode (ATM) network. Thus, a separate transmission protocol is not required for each different type of transmission media.

Abstract: The present invention provides a method and apparatus for multi-protocol, point-to-point communications which allocates processing tasks between a processor of an end point device and a processor of a communication device. The processor of the end point device performs all higher level protocol processing and the processor of the communication device performs lower level protocol processing. Internet service providers usually have several modems connected to each host computer for providing simultaneous point-to-point communication with a plurality of end users. The modems normally are located on cards which reside inside of the host computer, which may be a personal computer. To prevent the host processor from having to perform all of the protocol processing tasks for each session, the present invention provides for off-loading at least a portion of the Point-to-Point Protocol processing onto the modem processors. The host and the communication device or devices are interfaced via a shared memory device.

Abstract: A primary outer shell includes, in its most preferred embodiment, a base and a wall which includes at least one embedded foreign object and defines openings into an inner cavity containing a burnable candle member which causes the outer shell to glow and cast shadows without melting. The outer shell is constructed according to a unique molding method which includes at least partially immersing a swollen distensible mold, such as a water-filled balloon, into a reservoir of molding material, such as wax, to allow the molding material to form a molded shell around the distensible mold. After the distensible mold with the attached molded shell is removed from the reservoir of molding material, it is placed upon a flat surface to form a flat bottom into the molded shell.

Abstract: A synchronous clock regeneration system is implemented in a modem to enable the generation of a clock waveform at the same frequency as that of the transmitting device. The synchronous clock regeneration system receives an error signal indicating the timing difference in the receiving modem and the remote modem. The value in the error signal is added to a value in an offset integrator which integrates all of the error signals produced in a given transmission. The data is then relayed to a modulo subtractor which subtracts a predetermined value from the data if the value of the data is greater than the predetermined value. The data is then introduced to the offset integrator for integration and to a waveform generator. The waveform generator uses the data to offset a supply waveform an appropriate amount to match the frequency of the remote modem. As a result, the waveform generator produces a waveform that synchronously and smoothly tracks the clock waveform generated by the remote modem.

Abstract: Disclosed is an arrangement, dopant source and method used in the fabrication of photocells that minimize handling of cell wafers and involve a single furnace step. First, dopant sources are created by depositing selected dopants onto both surfaces of source wafers. The concentration of dopant that is placed on the surface is relatively low so that the sources are starved sources. These sources are stacked with photocell wafers in alternating orientation in a furnace. Next, the temperature is raised and thermal diffusion takes place whereby the dopant leaves the source wafers and becomes diffused in a cell wafer creating the junctions necessary for photocells to operate. The concentration of dopant diffused into a single side of the cell wafer is proportional to the concentration placed on the respective dopant source facing the side of the cell wafer. Then, in the same thermal cycle, a layer of oxide is created by introducing oxygen into the furnace environment after sufficient diffusion has taken place.
