| 20110035188 | METHOD AND APPARATUS FOR ANALYZING TIME SERIES DATA - The present invention relates to a method and an apparatus for determining which one or more time series parameters of a plurality of time series parameters relating to operation of a system are correlated with a first operation state of the system. According to the invention, the method comprises providing time series data including data relating to a time series of each of the plurality of time series parameters; determining at least two first time periods, wherein the system is in the first operation state during the at least two first time periods; determining at least one second time period, wherein the system is in a second operation state during the at least one second time period; determining, for each respective time series parameter of the plurality of time series parameters, a first characteristic parameter relating to a first characteristic of the time series of the respective time series parameter for each of the at least two first time periods and the at least one second time period; and determining which one or more time series parameters of the plurality of time series parameters relating to the operation of the system are correlated with the first operation state of the system by determining, for each respective time series parameter of the plurality of time series parameters, whether or not the respective time series parameter is correlated with the first operation state of the system based on the first characteristic parameters of the respective time series parameter determined for each of the at least two first time periods and the at least one second time period. | 02-10-2011 |
| 20110019022 | ACTIVE PIXEL SENSOR APPARATUS FOR USE IN A STAR TRACKER DEVICE - The invention relates to an active-pixel-sensor (APS) apparatus for use in a star tracker device including an imager chip, said imager chip comprising an array of photo-diodes operating as optical pixels, and a logic circuit. The logic circuit is configured for reading out a pixel signal depending on an amount of light irradiated during a predetermined integration time and resetting the optical pixel upon termination of the predetermined integration time processing the pixel signals and to output the modified signals and for performing a non-destructive readout of the pixel signal during the integration time In order to distinguish Single-Event-Upset (SEU) contributions to the signal from star signal contributions, it is proposed to further configure the logic circuit to detect whether or not a discontinuity has occurred in the pixel signal during the integration time, and to modify the signal depending on the result of this detection. | 01-27-2011 |
| 20100294347 | METHOD AND MEANS FOR CONNECTING THIN METAL LAYERS - A configuration and method for bonding a thin metal layer to two workpieces, e.g. solar cells and film-backed/reinforced small contact strips including: (i) the backing film is removed from the solar cell; (ii) the two films/layers are pressed together; and (iii) the two parts are irradiated from the side of the rear contact of the thin-film solar cell. Preferably two or three laser treatment steps are used for removing the backing film of the thin-film solar cell in an ablation process by means of a short-pulse laser and riveting the first metal layer to the second metal layer by irradiating the same by means of a long-pulse laser. | 11-25-2010 |
| 20100171653 | Navigation-Satellite Tracking Method and Receiving Station - The invention relates to Navigation-satellite tracking method including at least one step of determining one-way range unambiguous observations for each of a set of satellites in view, wherein standard tracking channels ( | 07-08-2010 |
| 20090196329 | Spreading Codes for A Satellite Navigation System - One embodiment of the invention provides a method of creating a set of secondary spreading codes for use in a satellite navigation system comprising a constellation of satellites. Each satellite in the constellation employs a tiered spreading code comprising at least a primary code and a secondary code. Each satellite in the constellation is allocated a different secondary spreading code from the set of secondary spreading codes. The method involves generating an initial set of bit patterns, where each bit pattern represents a potential secondary spreading code. The method further involves performing an optimisation process on bit patterns within the initial set of bit patterns. As a result of the optimisation, at least some of the bit patterns in the initial set are modified or replaced, to create a final set of bit patterns for use as the set of secondary spreading codes. | 08-06-2009 |
| 20090147835 | RECEIVER AND TRANSMITTER FOR USE IN A SATELLITE NAVIGATION SYSTEM - A receiver is provided for use with a satellite navigation system comprising a constellation of multiple satellites. Each satellite transmits a signal incorporating a spreading code. The receiver includes at least one code storage unit that includes combinatorial logic for storing a memory code comprising a fixed pattern of bits including address decoding, wherein the stored memory code corresponds to a spreading code incorporated into a signal transmitted from a satellite. The receiver further includes a correlator for performing a correlation between an incoming signal and the stored spreading code from the one code storage unit. | 06-11-2009 |
