Inventor: ONISHI MASAHIKO
IPC: H03F1/32
Filed: 2009-09-30
Abstract: Disclosed is a distortion compensation circuit that efficiently compensates for distortion. A distortion compensation circuit (20) comprises a sampling memory unit (21), which accumulates an input signal and an output signal from an amplifier (4), a model estimation unit (22), which reads the input and output signals that are accumulated upon the sampling memory unit (21), estimates a model that represents an input/output characteristic of the amplifier (4), and outputs a coefficient that denotes the model thus estimated, and a distortion compensation unit (23), which compensates for a distortion of the amplifier (4), based on the coefficient. The distortion compensation circuit (20) further comprises a control unit (25), which causes the accumulation of the input signal and the output signal upon the sampling memory unit (21) of a predetermined length, and controls the sampling memory unit (21) to accumulate the input and output signals anew in order to obtain a new coefficient after the distortion compensation is carried out by the distortion compensation unit (23) according to the coefficient that is obtained from the input and output signals that have been accumulated upon the memory unit.

Patent CA-2753927-A1 (CA)
Inventor: VICKERS MICHAEL T
IPC: A01C23/00
Filed: 2003-10-09
Abstract: The improved sprayer system of the present invention utilizes a docking drogue and probe assembly to quickly and easily allow refilling of the sprayer tanks with a material from an enlarged nurse tank. The coupling of the drogue and probe allows for fluid communication, as well as electronic transmission of material data to a processor in the prime mover. This processor software also receives input regarding field data and crop data, as well as feedback data from the sprayer regarding the material application. A GPS system on the prime mover allows for tracking the spraying operation, while a time stamp in the processor software tracks the timing of the spraying operation. This system thus allows for accurate accountability and traceability for the use of materials during the spraying operation.

Title: Using a custom media library to secure digital media content
Inventor: RISAN HANK
IPC: G06F21/24
Filed: 2010-05-26
Abstract: A system and method for using a custom media library to secure digital media content on a computing system is disclosed.    The method includes directly linking the custom media library with a copyright compliance mechanism (CCM)-enabled playback/recording application. In addition, the custom media library generates a new pathway distinct from a commonly used data pathway of the CCM-enabled playback/recording application and a media rendering subsystem of an operating system. Also, a CCM is alerted to monitor a plurality of media subsystems of the computing system. In so doing, a raw media file may be securely passed from the CCM-enabled playback/recording application via the custom media library and over the new pathway to a media subsystem of the operating system that is monitored by the CCM, such that the raw media file is rendered, playable and copyable in a secure environment.

Abstract: A process and an apparatus are disclosed for a compact processing assembly to recover C2 components (or C3 com-ponents) and heavier hydrocarbon components from a hydrocarbon gas stream.  The gas stream is cooled and divided into first and second streams. The first stream is further cooled to condense substantially all of it, expanded to lower pressure, and supplied as top feed to an absorbing means. The second stream is also expanded to lower pressure and fed to the bottom of the absorbing means. A distillation vapor stream from the absorbing means is heated by cooling the gas stream and the first stream. A distillation liquid stream from the absorbing means is fed to a heat and mass transfer means to heat it and strip out its volatile components while cooling the gas stream. The absorbing means and the heat and mass transfer means are housed in the processing assembly.
