  • Publication number: 20110136457
    Abstract: A method and system for the wireless terminal receiving sensitivity performance test based on a data mode are provided. The method comprises: building a human body model, in which the upper limb of the model holds the device under test at a predefined distance in front of the head of the model; taking the antenna of the device under test as the origin to build a spherical coordinate and selecting a testing point in the spherical coordinate; placing the model under the circumstance of a full-anechoic chamber; enabling the device under test to work in a data mode, and collecting the receiving power at the testing point in the spherical placement system using the testing antenna, so as to obtain the total power receiving sensitivity of the device under test. In this way, the performance influence on the mobile terminal from the human body coupling of the human being in a data mode can be actually reflected, the reality is high and the usage is easy.

  • Publication number: 20110122852
    Abstract: A method and apparatus for transmitting two signals on a single channel comprising a single frequency and a single time slot are disclosed. The method includes: generating a first training sequence from a first set of training sequences; generating a second training sequence from a second set of training sequences. The first and second training sequences have a low cross-correlation ratio with respect to each other; and the second set of training sequences is different from the first set of training sequences. First and second data are generated. The first data is combined with the first training sequence to produce first combined data and the second data is combined with the second training sequence to produce second combined data. The first and second combined data are transmitted on the single channel by a single transmitting apparatus.

  • Patent number: 7947443
    Abstract: The electrical conductivity of DNA and other oligonucleotide constructs is dependent on its conformational state. Such a dependence may be harnessed for the electronic sensing of external analytes, for instance, adenosine or thrombin. Such a DNA sensor incorporates an analyte receptor, whose altered conformation in the presence of bound analyte switches the conformation, and hence, the conductive path between two oligonucleotide stems, such as double-helical DNA. Two distinct designs for such sensors are described that permit significant electrical conduction through a first or “detector” double-helical stem only in the presence of the bound analyte. In the first design, current flows through the analyte receptor itself whereas, in the second, current flows in a path adjacent to the receptor.

  • Publication number: 20110077017
    Abstract: The present patent application improves DARP by allowing multiple users on one time slot (MUROS). It comprises means and instructions for sharing signals on a single channel, comprising setting up a new connection, allocating a new time slot if there is an unused time slot on a channel frequency, selecting an used time slot for the new connection to share with an existing connection if there is not an unused time slot on the channel frequency, and selecting a different training sequence code for the new connection if the used time slot on the channel frequency has been selected for the new connection to share with an existing connection.

  • Publication number: 20100203854
    Abstract: The present patent application comprises a transmitting method and apparatus 240. A signal source 241 provides an input signal to a low-pass filter 242 which filters the input signal to produce a filtered signal. The filter 242 is selectively operable in a first mode in which the input signal is filtered within a narrower bandwidth; and in a second mode in which the input signal is filtered within a broader bandwidth. The filtered signal is output to a modulator 243 which modulates the filtered signal to produce a modulated signal. The modulated signal is output to a transmitter 244 which transmits the modulated signal.

  • Publication number: 20100041562
    Abstract: Microarray devices fabricated using microfluidic reagent distribution techniques are provided. As described herein, the invention encompasses microfluidic microarray assemblies (MMA) and subassemblies and methods for their manufacture and use. In one embodiment first and second channel plates are provided which may be sealed to a test chip in consecutive steps. Each channel plate includes microfluidic channels configured in a predetermined reagent distribution pattern. For example, the first channel plate may have a radial (linear) reagent distribution pattern and the second channel plate may have a spiral (curved) reagent distribution pattern, or vice versa. In one embodiment the first channel plate is connected to the test chip and at least one first reagent is distributed on the test chip in a first predetermined reagent pattern. The first reagent is then immobilized on the test chip.

  • Publication number: 20080253349
    Abstract: A smooth transition is effected between adjacent digital information bursts transmitted in different modulation formats by selecting a first sequence for a first digital symbol burst to be transmitted, which first sequence comprises a set of end symbols with a first particular symbol pattern. A second sequence for a second digital symbol burst is also selected for transmission after the first digital symbol burst, which second sequence comprises a set of start symbols with a second particular symbol pattern. The first digital symbol burst is modulated in a first modulation format and the second digital symbol burst is modulated in a second modulation format different than the first modulation format. Thereafter, the modulated first and second digital symbol bursts are transmitted.

  • Patent number: 7403867
    Abstract: A spectroscopy instrument that uses spectra produced from random binary sequence modulated data. Statistical estimation techniques are used to achieve resolution enhancement, while properly accounting for the Poisson noise distribution and other artifacts introduced by a modulator or “chopper” or other system components. A resolution similar to that of modern spectrometers can be achieved. Both static and dynamic behaviors are theoretically or measured experimentally accounted for in the model as determined. In one embodiment, the finite penetration of the field beyond the plane of the chopper leads to non-ideal chopper response, which is characterized in terms of an “energy corruption” effect and a lead or lag in the time at which the beam responds to the chopper potential.

  • Patent number: 7031877
    Abstract: A spectroscopy instrument that uses spectra produced from random binary sequence modulated data. Statistical estimation techniques are used to achieve resolution enhancement, while properly accounting for the Poisson noise distribution and other artifacts introduced by a modulator or “chopper” or other system components. Indeed, a resolution similar to that of modern spectrometers can be achieved with a dramatic performance advantage over conventional, serial detection analyzers. Both static and dynamic behaviors are theoretically or measured experimentally accounted for in the model as determined. In one embodiment, the finite penetration of the field beyond the plane of the chopper leads to non-ideal chopper response, which is characterized in terms of an “energy corruption” effect and a lead or lag in the time at which the beam responds to the chopper potential.
