In a transponder (19) for amplification of a received signal (60) into an antenna (1), to a signal (61) for retransmission, and where the retransmitted signal (61) possibly may have information superimposed, a quenched oscillator (5) is incorporated as amplifying element. The oscillator (5) is preferably of superregenerative type and exhibits negative resistance (30) for the received signal (60). Transponders according to the present invention may be introduced as system elements in a wireless or wire based network to work as intelligent or unintelligent connections in the network. The transponders can also be used in positioning systems.

Systems and methodologies are provided that employ an allocation lock, which permits only a single transaction to acquire space on a particular page at any one time. The allocation lock of the present invention facilitates operations of concurrent transactions at a subpage level (e.g., a row level), and in conjunction with a heap manager can enforce a set of conditions such that prior to a commit stage of a transaction, a space availability for a particular page can be typically assured (e.g., that transactions operating on various copies of the page do not consume all of storage space on that page), and reorganization of data around the page is mitigated (e.g., that a transaction need not move data around the page for purpose of merging various copies.)

Embodiments of the invention may provide for reducing interference in the front-end of a communications receiver. The cancellation circuitry may be utilized in conjunction with a preliminary rejection filter for improved rejection of out-of-band interference from other radio services or circuitry. The cancellation circuit may be placed in parallel with the preliminary rejection filter and may enhance suppression at the interference frequency by matching the gain and phase of the preliminary rejection filter prior to subtracting the matched signal from the preliminary rejection filter output. The cancellation circuit need not necessary know beforehand the characteristics of the preliminary rejection filter, the interference source, or the coupling mechanism, as it may adapt to unknown or varying interferers by adapting the matching gain and phase values based on the output of the preliminary rejection filter at tap points occurring both before and after application of the cancellation signal.

The invention relates to a method for calculating an approach trajectory of an aircraft (200) to an airport The aircraft is slaveable in terms of trajectory, thrust and/or speed. The aircraft is able to advance at reduced engine revs. The airport has a runway The approach trajectory terminates in an impact point (205) on the runway and has a high-altitude descent segment (217) and an intermediate geometric segment (207), to which the aircraft is slaved in terms of trajectory and speed. A step of calculating a final approach segment (208) at reduced engine revs and a landing segment is performed with a greater thrust than the reduced revs so as to prepare a possible go-around (209), to which the aircraft is slaved in terms of thrust and speed.

A computing platform for on-demand I/O channels, which enable secure application to dynamically connect to diverse peripheral devices of untrusted commodity OSes

Low-latency satellite Internet service from a commercial off-the-shelf two-way satellite Internet system for aircraft under marginal communications link conditions is provided. One or more identical Internet requests each having a unique ID are sent in rapid succession from the aircraft. The one or more identical Internet requests are received at a satellite and sent to a network operations center (NOC) where they are forwarded over the Internet to an appropriate Web site. Identical Web pages are retrieved for the identical Internet requests by the NOC and transmitted to the satellite and then relayed to the aircraft. The requested Web page data is fused for the requested Web pages into a single Web page response in accordance with the unique IDs in the server for viewing by a client PC with low-latency when a failure in transmitting and receiving identical Internet requests and requested Web pages occurs.

A system for use in a vehicle determining the type of terrain ahead of the vehicle, the system comprising; a processor configured to receive sensor output data from a plurality of vehicle-mounted sensors, including at least one radar sensor and at least one acoustic sensor, each for receiving a reflected signal from the terrain ahead of the vehicle; and a data memory configured to store pre-determined data relating sensor output data, for the or each acoustic sensor and the or each radar sensor, to a terrain type; wherein the processor is configured to compare the sensor output data with the pre-determined data to determine an indication of the terrain type corresponding to the sensor output data.

A method and system for monitoring the performance of end to end flows traversing a network with rapidly changing topology and with address translation and encapsulation. Multiple probes are deployed within the network and a dynamic mapping method used to enable probes to associate local address information with end to end flow identifiers.

A gas separation process for treating exhaust gases from multiple combustion sources. The invention involves directing an exhaust gas stream from one combustion step to a carbon capture step. An off-gas stream depleted in carbon dioxide from the carbon capture step is mixed with a second exhaust stream from a second combustion step to form a mixed gas stream. The mixed gas stream is passed as a feed stream across the feed side of a membrane that is selectively permeable to carbon dioxide over nitrogen and carbon dioxide over oxygen. A sweep gas stream, usually air, flows across the permeate side, and picks up the preferentially permeating carbon dioxide. The permeate stream withdrawn from the permeate side of the membrane is then recycled back to the combustor.

The present invention includes a system for use in a vehicle for determining the terrain type in proximity to a vehicle. The system comprises a processor configured to receive primary output data from at least one vehicle-mounted sensor, and secondary output data from a secondary data source; and a data memory configured to store pre-determined primary data relating primary output data for the at least one vehicle-mounted sensor to a particular terrain type, and store at least one data set relating to one or more terrain types. The processor is configured to compare the primary output data with the pre-determined data to determine an indication of the particular terrain type corresponding to the primary output data, and compare the secondary output data with a data set corresponding to the indication of the particular terrain type.

The present invention relates to a method for measuring the presence and/or the concentration of an analyte by means of a gas sensor arrangement and to a corresponding gas sensor arrangement. The gas sensor arrangement comprises a radiation-emitting radiation source, a gas measuring chamber, which may be filled with a test gas containing at least one analyte to be measured, and at least one radiation-detecting detector device which generates an output signal as a function of the presence and/or the concentration of the analyte. In order to be able to reduce the harmful effects of condensation water, which condenses in the gas measuring chamber, the gas measuring chamber according to the invention is heated before the measurement process, such that the wall of the gas measuring chamber assumes a temperature which lies above the dew point of the test gas.

To control the separation of a hot gas ejection jet within a rocket engine nozzle, the device comprises a jettisonable annular structure for placing around the outside wall of the nozzle at the gas outlet section thereof, which structure defines a radial extension around the nozzle so that in the presence of an outlet jet coming from the nozzle, it creates a low pressure zone in the vicinity of the bottom face of the device, thereby reducing jet separation inside the nozzle.

A lid for use with containers having a peripherally disposed edge with a rolled inside edge positioned around the container opening. The lid has a flange with a first rim projecting downwardly therefrom. The first rim has an edge engaging section with a plurality of concentrically positioned snap rings that each have a concavely shaped contact surface facing outward from the first rim to engage a curved surface on the rolled inside edge. The first rim is tapered inwardly such that the lower snap rings have a smaller diameter than the upper snap rings to allow the container to select which snap ring provides the best fit for snap engagement with the curved surface. The snap rings are made out of a material that deforms to the shape of the curved surface. A second rim projecting downward from the flange outwardly of the first rim provides a dust shield.

The tremolo locking device is a device applicable to tremolo bridge equipped stringed instruments such as electric guitars. One embodiment of the device provides the means for the instrument player to lock the tremolo at a repeatable position, preventing movement bi-directionally, or to stop the tremolo limiting movement in one direction. It also allows the player to unlock the tremolo bridge completely for its unencumbered full range of use. This is accomplished with a retractable stop assembly providing a repeatable stop location and a screw assembly which holds the tremolo block against the stop.
