  • Patent number: 6032193
    Abstract: A system and method for controlling data transmissions between a remote node and a local node of a computer communications network. The network has a plurality of nodes that are interconnected for the exchange of datagrams defining a plurality of virtual circuits. A plurality of physical data links connected to the local node are used to connect the local node to the network and an interface establishes a connection from the local node to the remote node via a first one of the links. The interface assigns one of the virtual circuits to the first link and assigns another one of the virtual circuits to a second one of the links. The local node receives the remote-to-local datagrams of the assigned virtual circuits via their respective links whereby the collective throughput requirement of the plurality of datagrams is distributed among the plurality of links thereby increasing the speed of data transmission between the remote node and the local node.

  • Patent number: 5694376
    Abstract: A method and device for displaying time using a single segment member where the length and position of the segment member reflects the time. The device generally comprises a timer circuit to set and maintain hours and minutes of time, and a segment member control circuit which is responsive to the timer circuit and adjusts the length and position of the segment member to reflect the time maintained by the timer circuit.

  • Patent number: 5351296
    Abstract: A method and device for determining and securely transmitting an account code of a financial card over a communications link in a communications network to a remote location which also allows a telephone to be used concurrently to perform voice communications over the same communications link with the remote location. The device generally comprises a control circuit for controlling the operation of the device, a transmitter for transmitting data to the remote location, a receiver for receiving information from the remote location, and a power supply for supplying power to the device. The device also comprises a reader circuit for determining the account code of the financial card. In the preferred embodiment, the device also comprises an entering circuit, such as a keypad, for entering a secret PIN code portion of the account code.
