Title: Topically applied clotting material
Inventor: DRAKE JAMES FRANKLIN
IPC: A61K31/721
Filed: 2000-02-29
Abstract: A composition, system, articles and method for the enhancement of clotting in wounds with extravascular blood flow, especially where the surface of the tissue has been broken is described.  The system consists of biotolerable, porous particulates applied to the surface of a wound with liquid blood thereon. The porous nature of the particulate material, either free-flowing or packaged or restrained on or in a surface, enhances clotting. Chemical or biochemical agents, such as additional clotting agents, therapeutic agents, antibiotics, clot strengthening agents (such as fibrous structural materials), and the like may optionally be included on, with or within the porous particles. The particles may comprise such diverse materials as organics, metallics, inorganics, ceramics, and the like, both natural and artificial. It is generally preferred that the pore size distribution lies within a general range, and this range may vary from animal to animal and condition to condition, but generally falls within about 0.5 to 1000 micrometers or 3,000 to 200,000 Daltons.

Title: Multi-mode message routing and management
Inventor: KIRTLEY WILLIAM H
IPC: G06Q10/10
Filed: 2001-01-30
Abstract: Transmission of messages composed on one or more input devices to a single or multiple recipients by means of one or plural communication modes is facilitated. Such communication modes may include conventional or wireless telephone, facsimile transmission, pager, e-mail, postal mail or courier. Thus a message may be directed to a single recipient via multiple modes, such as e-mail and fax, in order to ensure the earliest possible receipt of the message;  or may be directed to multiple recipients by a single mode or by different modes. In the case of multiple-mode delivery, "escalation" rules may specify conditions under which different delivery modes may be sequentially employed.  Automatic follow-up to determine whether a message has been received, as well as automatic sender notification upon confirmation of receipt, may be employed. The system is capable of sending messages having embedded questions, and facilitating multi-question surveys.

Abstract: In an electric or hybrid electric vehicle, a voltage monitor (102) is directly coupled to a traction motor (38) and/or generator motor (30) to detect a permanent magnet induced voltage within the motor at a predetermined speed and no load condition. A controller (100) compares the detected permanent magnet induced voltage with an expected reference voltage that represents an expected permanent magnet induced voltage at full magnetization and the predetermined speed.      The comparison includes identifying points of synchronization and using those points to determine a difference in the detected permanent magnet induced voltage that is caused by a faulty component.
