Abstract:
This invention discloses a detection method for an ion migration spectrum which comprises: acquiring an ion migration spectrum of pure carrier gas and an ion migration spectrum of carrier gas containing a test substance sample; and performing differential process on the ion migration spectrum of said pure carrier gas and the ion migration spectrum of the carrier gas containing the test substance sample to acquire a differential spectrum, wherein the value of a characteristic peak of said differential spectrum represents properties of said sample of substances, said method avoids interferences on the migration spectrum from interference sources of the apparatus itself, thereby improving detection sensitivity and accuracy of the ion migration spectrum; and migration spectrum shift caused by variations in the environmental conditions can be found and corrected through the differential process on the migration spectrum of the pure carrier gas, thereby achieving self-stableness and self-correction of the ion migration spectrometer. This invention further discloses an ion migration spectrum detector and an ion migration spectrometer using said method.
Abstract:
A method of recycling a control wafer having a dielectric layer deposited thereon involves removing most of the dielectric layer by plasma etching leaving a residual film of the dielectric and then removing the residual dielectric film by a wet etching process. The combination of the dry and wet etching provides effective removal of the dielectric material without damaging the wafer substrate and any residual wet etching byproduct particulate remaining on the wafer substrate is then removed by APM cleaning and scrubbing.
Abstract:
The invention provides a multichannel analyzer for use in a multichannel spectrometer, which comprises a standard spectrum calibrator for obtaining energy calibration parameters of said multichannel spectrometer; an environment background spectrum calibrator for obtaining parameters of a current and a previous environment background spectrum; a peak shift detector for analyzing the parameters of the current and previous environment background spectrum to determine whether a peak shift occurs between them and to determine a correction coefficient of the peak shift; and a parameter corrector for correcting the energy calibration parameters of said multichannel spectrometer using said peak shift correction coefficient. The invention also provides a method for correcting a peak shift of a multichannel spectrometer adapted in the multichannel analyzer. The method for correcting and the multichannel analyzer can correct and monitor the peak shift of the multichannel spectrometer in real time.
Abstract:
A display system includes a display panel, a solar battery, an electric current measuring module, a memory, and a brightness adjusting module. The solar battery is for converting light energy into electric current. The electric current measuring module is for measuring electric current generated from the solar battery. The memory is for storing a pre-defined associative array of current values and their corresponding brightness values. The brightness adjusting module is for querying the associative array stored in the memory to get the corresponding brightness value, using the measured electric current value as a key, and adjusting the brightness of the display based on the brightness value returned from the associative array.

Abstract:
A DC offset estimation system is disclosed. A DC offset estimation system includes a carrier frequency offset estimator receiving an input signal and estimating a carrier frequency offset value, a symbol timing recovery unit providing a symbol boundary of the input signal, and a DC offset estimator estimating a DC offset value to compensate the input signal based on the input signal, the carrier frequency offset value, and the symbol boundary.
Abstract:
By understanding a website author's intention through an analysis of the function of a website, website content can be adapted for presentation or rendering in a manner that more closely appreciates and respects the function behind the website. A website's function is analyzed so that its content can be adapted to different client environments. A function-based object model (FOM) identifies objects associated with a website, and analyzes those objects in terms of their functions. Desktop oriented websites are adapted for mobile devices based on the FOM and on a mobile control intermediary language.
Abstract:
A structure of fluorescent lamp, which includes a sealed tube, electrode sets, and a passive luminous coating layer or a passive luminous body, is provided. The sealed tube is filled with a glow discharge medium, and electrode sets are assembled on two ends of the sealed tube to be contacted with the glow discharge medium and provide an electrical power to generate the electrical-glow-discharge of the glow discharge medium for emitting a glow-discharge light. The passive luminous coating layer or the passive luminous body is disposed on an outer surface of the sealed tube. The passive luminous coating layer or the passive luminous body absorbs the glow-discharge light to emit a luminous light with corresponding wavelength without being contacted with the glow discharge medium. Thus the interaction between glow discharge medium in the sealed tube and the luminous material is prevented.

A signal transmission cable with adaptive contact pin reference structure includes a first cable having a connecting edge; a second cable having a connecting edge; a component lay-out section having a first lateral edge adjacent to the connecting edge of the first cable, and a second lateral edge; and an overlapping section having an inner lateral edge adjacent to the second lateral edge of said component lay-out section with a folding line formed between them, and an outer lateral edge adjacent to the connecting edge of the second cable with another folding line formed between them. Signal transmission lines included in the component lay-out section and the first cable are correspondingly connected with one another, and signal transmission lines included in the overlapping section are correspondingly connected to those included in the second cable and the component lay-out section.
Abstract:
Because the back-and-forth movement by hand is slower and more strenuous than the leftward-and-rightward swinging, a handheld image-tracking device, which can be applied to an optical mouse or a handheld scanner, uses a rectangle-shaped sensing array to save area of the sensing array and lower down the production cost for the device by reasonably reducing the back-and-forth sensing area for the sensing array; and, so, an amount and time spent for a data comparison in the device is lessened.
