Abstract: A front side bus swizzle mechanism modifies the front side (address and data) bus on a chip so that, when the chip is positioned on one side of a printed circuit board, connection to a second chip located on the opposite side of the printed circuit board is simplified. The simplified connection may result in less complexity and minimize the consumption of additional printed circuit board real estate.

Abstract: A hyperbaric oxygen chamber for treatment of large animals such as horses is disclosed. The chamber is large enough for a horse to fit inside and comfortably move around. A specially designed davit door, though quite heavy, is easily manipulated and may be used to corral the horse during ingress or egress, and is serviceable using fluorocarbon lubricants. The door, sidewalls, and floor of the hyperbaric chamber are coated with a static dissipative polyurethane material suitable for oxygen environments and may protect the horse from injury and prevent sparks. The flooring is specially designed to allow the horse to eliminate during treatment, and may be cleaned easily and thoroughly without disassembly. The control mechanisms of the hyperbaric chamber include electro-pneumatic controls, for avoiding a fire hazard.

Abstract: A power system is disclosed for receiving dual alternating current sources and delivering direct current to drive a load. The power system comprises four power supplies and two transfer switch modules, any of which may be removed and replaced without disabling the power system. Three of the power supplies deliver current to drive the load while the fourth is redundant. A transfer switch control circuit activates relays within the transfer switch modules, in response to a change in the voltage maintained by one or both AC sources. As long as one of the AC sources maintains a voltage within a predetermined voltage range, three of the power supplies deliver current to drive the load.
