IPC: G06F13/40
Filed: 1999-06-04
Abstract: A peripheral interconnect for a computer system comprising a bridge, a peripheral bus, and a peripheral device, wherein at least one of these components is adapted to selectively operate in either a high performance mode or a low performance mode, the high performance mode using a first operating speed and a first protocol, and the low performance mode using a second operating speed which is lower than said first operating speed, and a second protocol which is different from the first protocol. The disclosed embodiment provides a high performance mode with a 100 MHz speed and a protocol that disallows pacing, and a low performance mode that uses a 66 MHz or 33 MHz speed and a standard PCI protocol that allows pacing. The high performance operating speed can be twice the low performance operating speed, by doubling the clock frequency and clocking data on only one clock edge, or by clocking data on both a rising edge and a falling edge of a clock signal while operating at the lower clock frequency. High performance adapters can provide split transaction capability, with a high performance bridge having the ability to support split transactions or alias split transactions to delayed transactions. Backward compatibility may also be provided for optional features such as hot-pluggability.

Title: Method of controlling the diameter of a clear extruded tube
Inventor: NIELSEN NIEL EDWIN
IPC: A22C13/00
Filed: 1999-09-21
Abstract: A method and apparatus for controlling the diameter of a clear extruded molten tube wherein the extruded tube contains a volume of a clear liquid and the level of the liquid is indicative of the tube diameter so the level rises as the tube diameter decreases. A light beam passing through the tube is refracted from a straight line path when the liquid level rises above the level of the beam. The refracting of the beam in turn triggers the introduction of air into the extruded tube to increase the diameter of the extruded, molten tube.
