Abstract: A group packet encapsulation and (optionally) compression system and method, including an encapsulation protocol increases packet transmission performance between two gateways or host computers by reducing data-link layer framing overhead, reducing packet routing overhead in gateways, compressing packet headers in the encapsulation packet, and increasing loss-less data compression ratio beyond that otherwise achievable in typical systems. Packets queued at a node configured in accordance with the present invention are classified, grouped, and encapsulated into a single packet as a function of having another such configured node in their path. The nodes exchange encapsulation packets, even though the packets within the encapsulation packet may ultimately have different destinations. Compression within an encapsulation packet may be performed on headers, payloads, or both.

Abstract: An inductive output tube (IOT) of a multi-staged depressed collector provides improved efficiency by approximating a Brillouin electron beam flow. In one embodiment, an IOT is provided with an electron gun that generates an electron beam, a tube body, a multi-staged depressed collector for collecting the electron beam, and a magnetic solenoid. The electron beam travels through the tube body. The magnetic solenoid produces a magnetic flux that focuses the electron beam as it travels through the tube body. The magnetic flux includes a portion that threads through the electron gun. The IOT is adapted to reduce this portion of the magnetic flux in order to provide improvements in the efficiency of the IOT.

Abstract: A method of increasing a cell capacity in a mobile communication system is disclosed. In the present invention, the cell capacity is increased by a gain control of traffic channels in a CDMA mobile communication system which can secure the cell capacity and increase the whole cell capacity by lowering the powers of the traffic channels allocated to a cell to a predetermined level. Thus, even when a call allocation is abnormal due to a decrease of forward exess capacity value, the present invention allows an allocation of normal and handoff calls.

Abstract: The failure mail identification section and delivery status notification mail identification section identify whether or not the received E-mail data is failure mail and delivery status notification mail, respectively. Based on the identification result, the specific information extraction section extracts information necessary for output from the E-mail data. The format conversion section converts the extracted data to facsimile data. The data edit section edits the converted data. The edited data is transmitted by the facsimile communication unit to the G3 facsimile via PSTN. This allows failure mail and delivery status notification mail to be distinguished from normal E-mail, saving recording paper.

Abstract: A technique for a time division multiplex system in which access to shared broadcast communication media is granted on a demand basis. Particular connections are assigned slot times at the transmitter based on demand. However, no specific information regarding the assignment of time slots need be communicated to the receivers. The transmit side employs a forward error correction technique followed by multiplication by a cover sequence unique to each connection. All receivers listen to the broadcast transmission channel all of the time. The receiver assigned to each connection decodes the signals in such a manner that only the receiver with the correct cover sequence assigned to a particular connection will successfully decode the data associated with that connection. Data frames that fail the forward error correction process are discarded, and only those frames which are successfully decoded are passed up to a higher layer.

Abstract: A mono-band planar inverted F antenna (PIFA) structure comprises a planar radiating element having a first area, and a ground plane having a second area that is substantially parallel to the radiating element first area. An electrically conductive first line is coupled to the radiating element at a first contact located at an edge on a side of the radiating element. The first line is also coupled to the ground plane. An electrically conductive second line is coupled to the radiating element at second and third contacts located along the same side as the first line, but at different locations on the edge than the first contact. Useable bandwidth of the PIFA is increased by using multiple contact locations to couple the conductive second line to the radiating element. The first and second lines are adapted to couple to a desired impedance, e.g., 50 ohms, at frequencies of operation of the PIFA.

Abstract: The present invention describes a system and method for communicating voice and data over a packet-switched network that is adapted to coexist and communicate with a legacy PSTN. The system permits packet switching of voice calls and data calls through a data network from and to any of a LEC, a customer facility or a direct IP connection on the data network. The system includes soft switch sites, gateway sites, a data network, a provisioning component, a network event component and a network management component. The system interfaces with customer facilities (e.g., a PBX), carrier facilities (e.g., a LEC) and legacy signaling networks (e.g., SS7) to handle calls between any combination of on-network and off-network callers. The soft switch sites provide the core call processing for the voice network architecture. The soft switch sites manage the gateway sites in a preferred embodiment, using a protocol such as the Internet Protocol Device Control (IPDC) protocol to request the set-up and tear-down of calls.

Abstract: An apparatus for and method for acquiring synchronization for use in communications systems, i.e., acquiring the presence of a packet of data and associated timing information. A sequence of symbols having known rotation and phase is transmitted to the receiver. The receiver attempts to match the received vectors in a predefined manner in order to determine whether a signal or noise is being received. CSK modulation is used for the synchronization acquisition stage and, any desired data carrying modulation may be switched to once synchronization is obtained, which may or may not be CSK. The transmitter transmits data in the form of packets to the receiver, wherein each packet is preceded by a preamble comprising a number of symbols. The length of the preamble can be any suitable number of symbols such that the receiver is able to synchronize with the transmitter. The preamble comprises a sequence of rotated or non-rotated symbols, inverted or non-inverted (or generally phase-rotated by some amount).

Abstract: A voice mail system employs caller-specific sub-mailboxes that are created within a voice mail account owner's mailbox so that a caller designates an access pincode for the sub-mailbox and then has access to the sub-mailbox for leaving messages, deleting messages, and re-ordering messages. Consequently, the voice mail systems achieve increased flexibility in accessing previous messages by one caller from multiple telephone locations, increased overall productivity of voice mail system users, the capability to allow a mailbox owner to prioritize the playing of recorded messages, and minimized connection time and battery consumption of portable, handheld devices accessing the voice mail system.
