Title: Moisture sensing strips
Inventor: HILL CLYDE D
IPC: G01M3/16
Filed: 2006-03-29
Abstract: A water leakage monitoring and response system for residential and commercial use. A flexible, elongated moisture sensor strip for placement on a floor or adjacent a baseboard or plumbing fixture comprises flexible upper and lower wires separated by a water permeable, nonconductive layer, and nonconductive upper and lower layers that extend away from the wires to form margins for attaching the strip to a surface and for wicking moisture toward the wires. Alternatively, the wires are laterally spaced-apart within the strip and/or the strip assumes the form of a pad to cover a surface area. In use, a plurality of strips/pads are wired to input jacks of a battery-powered electronic interface unit that provides audible and visual signals when moisture shorts the wires in the strips/pads. The unit also provides audible warning of low-battery power and can signal a home security system when a leak is detected.

Title: Anode-supported sofc with cermet electrolyte
Inventor: COIMBRA DAVID
IPC: H01M8/12
Filed: 2004-12-01
Abstract: Novel solid oxide fuel cell (SOFC) article and method of manufacture with improved properties at lower costs. The structural features and methods involve fabricating an anode (i.e., fuel electrode); applying a cermet electrolyte, which includes a mixture of ceramic and electrochemically active substances, and applying a cathodic layer. The cermet electrolyte containing a small amount of transition metal reduces the thermal expansion mismatch with the anode, and allows for a graded structure of the electrochemically active substances across the anode/electrolyte structure. Under operating conditions, a dense electrolyte and metal oxide sub-layer exist on the oxidized side (cathode side); while the other side of the electrolyte (reducing side) is made of a porous sub-layer containing transition metal. The tailoring of the amounts of metal present in the anode and the cermet electrolyte allows for greater power output and enhanced electrochemical performance, while maintaining the structural integrity and reliability of the SOFC.

Title: Materials location system and selecting method of materials receiving locations
Inventor: ONO SATORU
IPC: G06Q10/00
Filed: 2007-01-10
Abstract: Working efficiency improvement of shipping and receiving operations in a materials storage location is contemplated. An optimal location is provided so as to minimize work volume in shipping operation when receiving materials control objects in a materials storage location to improve working efficiency in the materials stockroom. As means to achieve it, a location information of the materials control objects stocked in the materials storage location and vacant area where the materials control objects to be received can be stocked are calculated by use of location information of the materials control objects in the materials storage location and materials dimensions and shape information represented by the three-dimensional CAD used in design to select and decide the area to minimize work volume when shipping. Consequently, shipping operation efficiency can be improved. Further, provision of means to obtain automatically location information of the stocked materials control objects enables to obtain location information of the stocked materials control objects at a spot away from the materials storage location, and thus makes it possible to reduce traveling time of operators to the materials storage location.
