Abstract: A method for exchanging data in a first host computer coupled to a network. The network is also coupled to a second host computer. The method includes employing a first Transmit Control Block (Tx TCB) to facilitate transmitting first data associated with a bi-directional data flow from the first host computer to the second host computer. The first data is transmitted using the TCP protocol. The first Tx TCB is associated with the first host computer and is configured for storing transmit-facilitating parameters associated with the transmitting the first data using the TCP protocol. The method also includes employing a first Receive Control Block (Rx TCB) to facilitate receiving second data associated with the bi-directional data flow. The second data is transmitted from the second host computer to the first host computer using the TCP protocol.

Abstract: A printed circuit board includes a power plane and a ground reference plane that includes two opposite sides. The power plane is positioned proximate one side of the ground reference plane. A signal layer is positioned proximate the other side of the ground reference plane to isolate the power plane from the signal layer. Any noise on the power plane or the signal layer is thus isolated by the intervening ground plane.

Abstract: A method for transmitting transmit data associated with a bi-directional data flow between a first host computer and a second host computer. The first host computer and the second host computer are coupled via a computer network. The method includes storing transmit-facilitating parameters employed for the transmitting the transmit data in a first control block. The first control block is implemented in the first host computer and associated with the bi-directional data flow. The transmitting the transmit data is performed in accordance with the TCP protocol. The method also includes employing the transmit-facilitating parameters in the first control block to facilitate servicing a transmit request pertaining to a given portion of the transmit data from the first host computer to the second computer.

Abstract: A method for transfer of digital data, comprising a succession of one values and zero values, across a capacitive interface. The interface includes a first capacitor and a second capacitor in parallel, linking a first circuit to a second circuit. First digital data is transferred from the first circuit to the second circuit, and a reference clock is provided by the first circuit and transmitted with the first data to the second circuit for recovery thereby. A first set of bi-level signals representing the zero values of the first data is applied to the first capacitor, such that a repeating level transition of the reference clock corresponds to a first level transition of the first set of bi-level signals. A second set of bi-level signals representing the one values of the first data is applied to the second capacitor, such that the repeating transition of the reference clock corresponds to a second level transition of the second set of bi-level signals. The clock and data are then recovered.

Abstract: A method for receiving receive data associated with a bi-directional data flow between a first host computer and a second host computer. The first host computer and the second host computer are coupled via a computer network. The method includes storing receive-facilitating parameters employed for the receiving the receive data in a first control block. The first control block is implemented in the first host computer and associated with the bi-directional data flow. The receiving the receive data is performed in accordance with the TCP protocol. The method also includes employing the receive-facilitating parameters in the first control block to facilitate receiving a given portion of the receive data at the first host computer from the second computer.

Abstract: A method in a target device for partially reordering a plurality of data packets transmitted from a source device. The source device is coupled to the target device via a computer network. The method receiving a first set of data packets from the transmitted device, and ascertaining whether the first set of data packets represents a set of data packets that the target device expects to receive next. If the first set of data packets does not represents the set of data packets that the target expects to receive next, the method includes storing the first set of data packets in a memory buffer of the target device. The storing includes arranging the first set of data packets in the memory buffer such that data packets in the memory buffer, including the first set of data packets, are in order in the memory buffer.

Abstract: Methods and systems for operating an online marketplace for the sale of services associated with self-help moving and relocating are described. A customer enters an online marketplace where service providers offer services relating to moving and relocating, specifically in the “do-it-yourself” moving field. The venue for the online marketplace is an Internet web site or a site on a computer network and is operated by a host that determines which service providers will be listed on the site. A typical self-help moving customer may enter the marketplace after completing an initial transaction with the host, such as reserving a moving truck or trailer and other moving equipment. In many instances this transaction is what initially draws the customer to the site. Once in the marketplace, the customer can view informational content on numerous vendors providing services relating to moving and relocating.

Abstract: Disclosed are improved modem apparatus and systems for interfacing with a Public Switched Telephone Network (PSTN). The modem includes a broadband data channel. A high-frequency transformer isolates the broadband data channel. An external power source provides one or more power levels for the broadband data channel. A transformerless embodiment using high voltage capacitors for isolation is also disclosed. The invention also provides a hybrid modem having a broadband data channel and a Voice Band (VB) data channel. Isolation is provided alternatively by a high-frequency transformer or high voltage capacitors.
