Title: Power interrupt management for an aircraft electric brake system
Inventor: GRIFFITH TODD T
IPC: B60T8/17
Filed: 2007-08-24
Granted: 2011-11-08
Abstract: An electric brake system (100) for an aircraft as described herein electrically actuates brake mechanisms (108) in a seamless manner when a power interrupt condition is experienced. While operating in an autobraking mode and in response to a power interrupt condition, the electric brake system (100) preserves the last brake actuation command generated by the autobrake function. After normal operating power is reestablished, the last brake actuation command is retrieved and processed by the electric brake system (100). While operating in a pedal braking mode and in response to a power interrupt condition, the electric brake system (100) discards the last brake actuation command generated from brake pedal interaction. After normal operating power is reestablished, the brake pedal data is refreshed to generate a new brake actuation command. These procedures reduce lurching and unexpected brake actuation levels following a power interrupt in the electric brake system (100).

Abstract: Concentrations of a target analyte in a gas mixture containing one or more background analytes having potentially interfering spectral absorption features can be calculated by compensating for background analyte absorption at a target wavelength used to quantify the target analyte. Absorption can be measured at a reference wavelength (302) chosen to quantify the concentration of the background analyte. Using a background gas adjustment factor or function, the absorption measured at the reference wavelength can be used to calculate absorption due to the background analyte at the target wavelength (304) and thereby compensate for this background absorption to more accurately calculate the target analyte concentration in real or near real time (306). Additional background analytes can optionally be compensated for by using one or more additional reference wavelengths.

Abstract: A method of recovering hydrocarbons from hydro carbonaceous materials can include forming a constructed permeability control infrastructure (100). This constructed infrastructure defines a substantially encapsulated volume. A comminuted hydro carbonaceous material can be introduced into the control infrastructure to form a permeable body (120) of hydro carbonaceous material. The permeable body (120) can be heated sufficient to remove hydrocarbons therefrom such as by using heating conduits (118,126). During heating the hydro carbonaceous material is substantially stationary as the constructed infrastructure (100) is a fixed structure. Removed hydrocarbons can be collected as liquid products (136) and gaseous products (140) for further processing, use in the process, and/or use as recovered.

Abstract: An arc fault circuit interrupter includes separable contacts, an operating mechanism, a current sensor sensing current flowing through the contacts and outputting a sensed current, and a processor determining and storing peak values of the sensed current for plural half-cycles. The processor provides arc fault detection, determines whether a first predetermined plurality of half-cycles occur in succession and correspond to non-unity power factor, and responsively inhibits the detection for a first predetermined time, and whether a second predetermined plurality of half-cycles occur in succession, each with smaller peak amplitude than that of an immediately preceding half-cycle of like or differing polarity, and responsively inhibits the detection for a second predetermined time. The processor determines that the detection is not inhibited for the first and second predetermined times, and responsively indicates that any of the half-cycles having a peak amplitude greater than a predetermined amount is a parallel arc.

Abstract: Herein is described a fluid that is useful in consolidating a formation without the use of a gravel pack and screen. In particular, the fluid is useful in consolidating heterogeneous formations where the permeability is not uniform over the total formation thickness, e.g. a formation having at least a first layer and a second layer, wherein the permeability of the first layer is greater than that of the second layer. The fluid comprises at least one of a resin, a curing agent, and a surfactant, wherein the fluid is self-diverting. Optionally, a catalyst or other additives, such as an oil wetting agent, can be used. Fluids of the present invention are self-diverting, i.e. in a formation comprising at least a first layer and a second layer, wherein the first layer has a higher permeability than the second layer, the depth of penetration of the fluid into the second layer will be greater than that predicted from the permeability ratio (the ratio of the permeability of the first layer to that of the second layer). Self-diversion can be achieved by structuring the fluid by incorporation of another phase, either liquid or gas, or by using an additive in the fluid. Also disclosed are methods for using such a fluid to consolidate a formation, especially a heterogeneous formation.
