Abstract: Disclosed are methods and apparatuses for generating the estimates of receiver's coordinates and/or time offset for a moment of time tn without large errors caused by short-term shading of a part of the observable global positioning satellites and also without large dynamic errors caused by the receiver movement. The receiver may be stationary or mobile (i.e., rovering). A set of snapshot-solution values for the position coordinates and time offset of the receiver at the time moment tn, and a set of predicted values for the position coordinates and time offset of the receiver at the time moment tn are generated. The accuracy of each of these sets are determined, and a set of refined estimates for the position and time offset of the receiver is generated based the snapshot solution values, the predicted position values, and the accuracies.

Abstract: A compact inlet system for redirecting the flow of gas to a gas treatment apparatus is shown. The inlet system is used to redirect a high volume flow of gas, such as the effluent from an industrial process, by as much as 180° while introducing the gas flow uniformly into the treatment apparatus. The inlet system has a divergent transition section to slow the gas flow, a gas turning section to redirect the gas flow by 90°, and a gas inlet chamber which redirects the gas flow by an additional 90°, while at the same time introducing the gas flow uniformly into a treatment apparatus, such as a gas conditioning tower (GCT). The compact gas inlet chamber of the present invention has an elongate entrance, a circular outlet and a tapered midsection. When used with a GCT the greater uniformity provided by the present invention allows spray nozzles to be positioned within the throat of the entrance venturi of the GCT.

The memory is divided into blocks (1), each having a number of rows. The address decoder (2) is connected by word lines (3) to the cells in a row of the blocks (1) and a multiplexer (4) is adapted to select which block of memory to read data from. The memory device further includes a blocking means adapted to block the word lines when the memory device is in a CAM match read mode, such that several parallel hits in different blocks may be read without generating an invalid read-out.

Abstract: A method of determining the most cost effective manner in which to provide a given number of memory or logic gates for a particular application. The method takes into consideration both the cost per memory bit of fabricating memory cells on a semiconductor chip as a function of the number of memory cells on the chip (i.e, the chip size), and the costs of assembling multiple memory chips into a larger memory device using different assembly and packaging configurations. By considering the fabrication and packaging costs together, the most economically efficient combination of memory chip size and packaging method to produce a desired memory capacity can be determined.

Additional passageways enable auxiliary contact terminals to extend through the substrate. Clip connectors disposed on the substrate are used to make electrical contact to the auxiliary terminals. In a preferred embodiment, the sockets and clips are shaped and dimensioned to mate with the current and alarm contact terminals of a plug-in circuit breaker.
