Abstract: The present invention is directed to a system for providing information to an athlete concerning the efficiency with which the athlete is using energy in moving relative to the ground or some other surface. In one embodiment, the system includes a plurality of pressure sensors that are associated with a shoe and generate pressure related data. The system further includes a processing system that processes the pressure data produced by the sensors to determine energy efficiency related information and make this information available to the wearer of the shoe so that the wearer can, if needed or desired, takes steps to improve their energy efficiency.

Abstract: The present invention is directed to a diffusion substrate assembly that is suitable for use in fuel cells. The diffusion substrate exhibits low flow resistance for active fuel agents and electrochemical reaction products, high electrical cross plane conductance and a good mechanical integrity. In one embodiment, the diffusion substrate includes carbon micro-studs that are in a substantially parallel relationship to one another and extend substantially perpendicular to a supporting bed.

Abstract: The present invention is directed to a network attached storage system for storing data that provides the ability to “hot swap” a data storage device associated with the system while substantially reducing, during removal of the data storage device, the possibility that data being transferred between the data storage device and the exterior environment is lost or corrupted and/or damage to the data storage device.

Abstract: The present invention is directed to a network attached data storage system. In one embodiment of the invention, the system provides high data density by providing the capability to mount four data storage devices, such as disk drives, in a row that extends across the width of an enclosure that conforms to the 1U specification. In a further embodiment, the system includes a latch that allows a data storage device that is disposed on a carriage to be attached and detached from a receiving bay within a disclosure. The latch includes a sensor that provides an electrical signal which is indicative of when a user is disengaging the latch to remove the data storage device from the enclosure. This signal can be used to prevent any data that is being transferred to or from the data storage device from being lost and/or corrupted during removal of the data storage device.
