Patent number: 8980492Abstract: A control circuit controls power generation by a power cell in a presence of fuel and oxidant through electrical control. The control circuit may be extended to an array of power cells or array of banks of power cells to configure the cells or banks in series-row and column combinations to generate power in a selectable manner. The controller may include basic power maintenance and control of the array of power cells, and high level control modules may provide unique power generation control to cause the array to cold start, output time-varying waveforms, output multiple DC voltages from a single source of energy, regulate voltage or current, and so forth. Because the power cells may be configured in vast arrays, power cells may be connected to a group of other power cells in the array and driven with a time-varying voltage or pulse to self-clean catalyst of contaminants.Type: GrantFiled: March 2, 2007Date of Patent: March 17, 2015Assignee: Encite LLCInventors: Stephen A.

Publication number: 20100188265Abstract: A vehicle communication network provides information about traffic conditions in a local area on a near real time basis. An RF transceiver in a vehicle communicates with other transceivers in other vehicles to relay traffic condition related information. The traffic information can be provided to local vehicles equipped with transceivers, or roadside devices that participate in the communication network. The traffic information is derived from data that may include time, position, velocity, acceleration or other information related to traffic flow. The data can be derived from a GPS, accelerometer or other devices that are typically prevalent in automobiles, whether as standalone units or integrated into the automobile. The transceivers can implement an emergency messaging construct to permit rapid dissemination of traffic information that may be derived from collisions, slowdowns, congestion or other traffic conditions that may prompt drivers to slowdown or otherwise increase vehicle spacing.Type: ApplicationFiled: January 22, 2010Publication date: July 29, 2010Inventors: Lawrence W.

Publication number: 20090167513Abstract: A wireless vehicular positioning and communications system that combines inter-vehicular ranging and a self-organizing TDMA MAC protocol to both achieve more accurate positioning than is possible with GPS positioning and provide a deterministic channel for inter-vehicle communication. The band used for the system is divided into time slots, with each vehicle being able to obtain a time slot autonomously. Within a time slot, there is a ranging signal which occupies the full bandwidth; following the ranging signal, the band is divided into sub-bands. Some of the sub-bands are used to send packets according to the TDMA MAC protocol, and thus provide the deterministic channel; others are used for a non-deterministic channel which may be used for packets following the Internet Protocols. The system also uses mesh networking to permit vehicles to obtain advance warning of abnormal conditions in other vehicles.Type: ApplicationFiled: December 8, 2006Publication date: July 2, 2009Inventors: Lawrence W. Hill, Alexander Herman

Publication number: 20090149202Abstract: A system and method of determining and reporting on the position of a wireless device relative to a group of other wireless devices dispersed within a specified geographic area. The system includes at least one Query Unit, three or more Responding Units disposed at determinable locations within the specified geographic area, and one or more Mobile Units, which may correspond to additional Responding Units or units that function only as receivers. The Query Unit sequentially queries the Responding Units, and, responsive to the respective query messages, the Responding Units transmit corresponding response messages. One or more of the Mobile Units receive the query and response messages, and generate, for each query-response message pair, a set of time-difference-of-arrival (TDOA) measurements, which are used by the Mobile Units to determine their positions relative to the Responding Units.Type: ApplicationFiled: December 4, 2008Publication date: June 11, 2009Inventors: Lawrence W.
