摘要： A method is disclosed for reducing noise in a measured telemetry signal. The method includes tracking a characteristic of at least one harmonic of a noise component in the measured telemetry signal band. The at least one harmonic has a frequency outside a telemetry signal band. The characteristic of the noise component is determined for at least one other harmonic thereof. The at least one other harmonic has a frequency inside the telemetry signal band. A noise reference is generated from the characteristic of the in band harmonic, and the noise reference is combined with the measured telemetry signal to generate a noise-canceled telemetry signal.

摘要： A transmission mask or coded aperture is used in spectroscopy to compressively sample an optical signal. The locations of transmissive and opaque elements of the mask are determined by a transmission function. The optical signal transmitted by the mask is detected at each sensor of a plurality of sensors dispersed spatially with respect to the mask. A number of estimated optical signal values is calculated from sensor measurements and the transmission function. The optical signal is compressed by selecting the transmission function so that the number of measurements is less than the number of estimated optical signal values. A reconstructed optical signal is further calculated using signal inference. An imaging system created from plurality of encoded subimaging systems compressively samples an optical signal. Encoding methods include but are not limited to pixel shift coding, birefringent shift coding, transmission mask coding, micro-optic coding, diffractive coding, interferometric coding, and focal plane coding.

摘要： Systems and methods for automatically polling for data changes in an on-demand database service environment. A polling server communicates with application servers and client systems. Application servers send update messages to the polling server identifying which database objects have been updated, and client systems communicate with the polling server on a regular basis, rather than with the application server, to determine whether updates to a data object may have been made. When it has been determined that an update may have been made, the client system then sends a refresh request to the application server to request an update to the data object, thereby controlling (e.g., reducing) the number of refresh requests sent to the application server.
