Title: Electrochemical engine
Inventor: O'CONNELL DANIEL B
IPC: H01M8/06
Filed: 2000-10-11
Abstract: An electrochemical engine for a vehicle comprises a storage tank containing hydrogen-retention material which reversibly takes-up and stores hydrogen at a hydrogen-storage temperature and releases it upon heating to a release temperature. A fuel cell stack using the released hydrogen produces electricity and heat by-product. A primary coolant flow circuit extends from a radiator, through the fuel cell stack and the storage tank, and back to the radiator, and has a coolant-distribution valve intermediate the fuel cell stack and the storage tank. A bypass coolant flow line extends from the coolant-distribution valve to the radiator. During operation, the heat by-product of the fuel cell stack is transferred via the primary coolant flow circuit to the storage tank for heating the hydrogen-retention material to release hydrogen for fueling the fuel cell stack. The electrochemical engine further comprises a heat generator within a superheater coolant flow loop having a bypass valve intermediate the storage tank and the radiator operable to keep coolant within the superheater coolant flow loop and a secondary pump to circulate the coolant. Coolant in the superheater coolant flow loop is heated by the heat generator and circulated through the storage tank to further release hydrogen gas from the hydrogen-retention material.

Title: Mobile vehicle accident data system
Inventor: PANDOLFI RICHARD
IPC: G08G1/123
Filed: 2001-01-19
Abstract: One or more video cameras are mounted on the vehicle to make continuously a visual record of the scene in a region around the vehicle. Camera images during a time interval covering the current time and the recent past are stored on-board the vehicle, preferably, digitally recorded in a compressed format. In addition, data (e.g. one or more operating parameters such as speed, GPS data, engine, and/or brake operating parameters) from the vehicle's on-board embedded computers covering the present and recent past interval are also preferably digitally stored on-board the vehicle. An accident detector or detectors on-board the vehicle, for example a biaxial accelerometer, generate a trigger signal in response to an accident, such as the vehicle striking something or being struck by another vehicle. In response to an accident detector trigger signal, the data stored on-board the vehicle is automatically transmitted over a wireless link (e.g. public access links such as CDPD, satellite and Iredium or a private link) to a central data base. Data in the central data base is connected by a digital data network such as the Internet or a secured intranet and the data can be accessed via a computer terminal of an authorized party, such as an insurance adjuster for the company providing coverage to the vehicle, a self-insured entity, or a loss management facility.

La séparation de la suie de l'eau d'épuration (10) est améliorée au moyen d'un ou de plusieurs agents tensioactifs (6) qui permettent de rendre les particules de suie hydrophobes et oléophiles. On recycle enfin la suie récupérée vers le gazéificateur (2) afin de récupérer la valeur énergétique du carbone au cours de la réaction d'oxydation partielle. On peut augmenter le rendement énergétique total du processus de gazéification en évacuant la totalité ou une partie importante de l'eau du mélange de suie avant de recycler cette dernière. L'extraction de la suie de l'eau permet la régulation séparée des flux de recyclage de suie et d'eau, en fonction des conditions de réaction dans le gazéificateur (2).
