Abstract: A method for creating networks of perfusable microvessels in vitro. A mandrel is drawn through a matrix to form a channel through the matrix. Cells are injected into the channel. The matrix is incubated to allow the cells to attach inside the channel. The channel is perfused to remove unattached cells to create a parent vessel, where the parent vessel includes a perfusable hollow channel lined with cells in the matrix. The parent vessel is induced to create sprouts into the surrounding matrix gel so as to form a microvessel network. The microvessel network is subjected to luminal perfusion through the parent vessel.

The microvessel systems are integrated into devices that allow for controlled perfusion with fluids. The vessels may include cells from one cell type, for example, endothelial cells, or from combinations of two or more cell types.

Abstract: A wireless telephone includes first and second baseband processors. The first baseband processor functions as system master, and the second processor functions as system slave. The first baseband processor interfaces to system controls, such as power supply, man-machine interface (MMI), and the like. The master processor implements a first pair of buffers in the downlink direction and a second pair in an uplink direction. The buffers in the pairs are swapped periodically, based on an internal counter running on the master processor. The timing of the master processor is continuously adjusted to that of the slaved co-processor, by counting a number of samples received from the microphone respectively fed to the earpiece between the beginning of consecutive frames. The timing of the master processor is then adjusted accordingly. The output of the counter may be lowpass filtered to separate jitter from frequency deviation.
