Abstract: A method of transmission over a packet based network including providing data packets to be transmitted on the packet based network during a predetermined time interval and arranging the provided data packets in a transmission block according to desired transmission times of the data packets, such that one or more gaps remain between at least some of the data packets. The method further includes adding padding bytes to the transmission block in a manner which substantially fills the one or more gaps and providing the block for transmission on the packet based network.

Abstract: A single piece, plastic shim simplifies the process of shimming a fixture (such as a door) within a frame. The operation of the shim requires only that one piece of the shim be pulled so that the shim folds in on itself, filling the space between the frame and the fixture. Only a small portion of the shim extends beyond the frame, and needs to be cut. This arrangement avoids stress to the shim and the frame.
