    Abstract: Apparatus and methods for seeding an implantable medical device, such as a vascular prosthesis, with cells, such as endothelial cells, are described. The invention supports techniques for seeding a luminal surface of the device with axial centrifugation. Cells are introduced in suspension into the lumen of the device. The introduction of the cells may occur after a blood centrifugation product, such as platelet-poor plasma, is applied to the luminal surface. After the cells are introduced, the device is then subjected to centrifugation around a longitudinal axis defined by the lumen. Axial centrifugation causes the cells to concentrate toward and adhere to the luminal surface. Shortly after axial centrifugation, the seeded device can be presented for implantation in a patient. The implantable medical device may be inserted into a protective sleeve prior to seeding the device with cells, and the sleeve may or may not be removed prior to implantation.

    Abstract: In general, the invention is directed to devices and methods that are useful for surface preparation of implantable medical devices. In the case of a vascular graft, the invention presents devices and methods that enhance endothelial cell seeding by providing recesses in the luminal surface that can receive endothelial cells. When the device is constructed of a material such as expanded polytetrafluoroethylene (ePTFE), the recesses may be created by physical processing of the microstructures of the material. The physical processing lifts nodes from the surface, forming recesses that can receive endothelial cells.

    Abstract: A burst mode optical signal is transported as payload of a framed continuous bit-stream optical signal through an optical transport network. The optical bursts are all generated at a common nominal bitrate which equals substantially the payload bitrate of the continuous bit-stream optical signal. The bursts are converted into a continuous bit stream by filling gaps between the bursts with a predefined pattern. The continuous bit stream thus created is then mapped into frames to generate the framed continuous bit-stream optical signal for transmission.

    Abstract: A model train operating, sound and control system that provides a user with increased operating realism. A novel remote control communication capability between the user and the model trains. This feature is accomplished by using a handheld remote control on which various commands may be entered, and a Track Interface Unit that retrieves and processes the commands. The Track Interface Unit converts the commands to modulated signals in the form of data bit sequences (preferably spread spectrum signals) which are sent down the track rails. The model train picks up the modulated signals, retrieves the entered command, and executes it through use of a processor and associated control and driver circuitry. A speed control circuit located inside the model train that is capable of continuously monitoring the operating speed of the train and making adjustments to a motor drive circuit, as well as a novel smoke unit. Circuitry for connecting the Track Interface Unit to an external source, such as a computer, CD player, or other sound source, and have real-time sounds stream down the model train tracks for playing through the speakers located in the model train.

    Abstract: The synchronous digital communications system according to the invention serves to transmit electric signals optically. The electric signals to be transmitted are converted from electrical to optical form (E/O1, E/O2, E/On) and are transmitted using wavelength division multiplexing (WDM) or dense wavelength division multiplexing (DWDM). At least one optical connection is configured as a nonswitched connection using at least one wavelength per transmission section between optical network elements or optical and electrical network elements, and serves to transmit synchronization and information signals. This has the advantage that independently of the switched communication links, synchronization is constantly ensured throughout the network. Each network element (NE1, NE2, NE3) has at least one interface unit that is reserved for synchronization and that continuously receives signals at the wavelength (&lgr;1) reserved for synchronization.
