    摘要: Methods and apparatus for improving the performance of a conventional cellular telephone system. In a conventional system, a base station (12) located in a cell (10) both sends and receives signals to and from handheld phones (14). In one embodiment, the present invention employs a relay transceiver (18) located in the cell (10) to relay signals (20) from handheld phones (14) to the a base station (12). The handheld (14) still receives signals (16) directly from the base station (12), but the return signal (22) back to the base station (12) is accomplished through the relay transceiver (18).

    摘要: Small radio frequency tags for use in a motion capture system include a power source, circuitry for generating radio frequency identification signals, an antenna for transmitting the signals, and means for automatically activating the tags so that the tags begin transmitting the signals including a tag identification code when a cover is removed. The activation means may include a release strip that, when removed, opens or closes an electrical circuit that activates the tag and also exposes an adhesive covered surface of the tag so that the tag can then be adhered to a clothed or unclothed human body or other object to be tracked. The activation means can also include an optical sensor, an oxygen sensor, or other sensors. The battery and the antenna may be printed or constructed of film, thus allowing the tag to be small, thin, and flexible.

    摘要: Methods and apparatus for a collecting a human odor or DNA sample (S), analyzing the sample (S) and then determining a good romantic match is disclosed. In one embodiment, a customer purchases an AromaMatch™ Test Kit (14), which comprises a bottle of cleaning solution (20), a cotton ball (22) a sample patch (24), a sample bag (28) and a mailing envelope (30). The user (10) opens the kit (14), cleans a patch of skin somewhere on his or her body, and then applies the patch (24). After wearing the patch (24) for an appropriate time period, the patch (24) is removed, and placed in the sample bag (28). In an alternative embodiment, the user obtains a DNA sample using a cheek swab (42) or a spit cup (43). The user (10) writes his or her password on the sample bag (28) or some other container, and then mails it in the return envelope (30). A laboratory analyzes the sample patch or DNA sample (24), and determines a set of genetic attributes (G1) that are associated with the sample (S). The user (10) receives an analysis report by mail, or views the results of the analysis on a website (18), such as www.AromaMatch.com. In another embodiment, a customized perfume is manufactured that is based on biological agents that are selected to match the set of genetic attributes identified by the analysis. The perfume may be worn to stimulate sexual self-confidence or to enhance the attractiveness of another person.

    摘要: A method for designing a digital filter, includes: (a) selecting a predetermined number of current sets of coefficients for the digital filter; (b) selecting a metric for evaluating coefficients of the digital filter; (c) computing a metric for each current set of coefficients; (d) deriving a next set of coefficients based on a subset of the current set of coefficients; (e) computing the metric for the next set of coefficients; (f) replacing a selected one of the current set of coefficients based on comparing the metric for the next set of coefficients with the metric for the selected current set of coefficients; and (g) iterating steps (a) to (e) until a termination criterion is met. In one embodiment, the selected metric represents a desired stop band response. The next set of coefficients may be derived by adjusting a first current set of coefficients by a weighted difference between a second current set of coefficients and a third current set of coefficients. The weighted difference may be obtained by multiplying a predetermined factor to the difference between the second current set of coefficients and the third current set of coefficients. In one embodiment, a scaling is performed such that the next set of coefficients does not include a pole outside of the unit circle.

    摘要: Systems and methods are disclosed herein to use sieving to reduce the number of hypotheses and the length of time for acquisition of GPS satellite signals. In sieving, hypothesis testing is performed after a short non-coherent integration duration on a first set of hypotheses. At the end of the non-coherent integration time, multiple candidate hypotheses having high likelihood of signal detection are identified. Further non-coherent integration of each candidate hypothesis is performed by using a tracking loop to remove Doppler frequency and code phase variations on the signal. In parallel, additional hypotheses testing is performed on a second set of hypotheses. At the end of the next non-coherent integration time, the best candidate hypotheses among the candidate hypotheses sieved from the first set of hypotheses running in the tracking loops and the candidate hypotheses from the second set of hypotheses are identified. This new set of candidate hypotheses replaces the previous candidate hypotheses and is tracked by the tracking loops. This process of short non-coherent integrations followed by track is repeated until a candidate hypothesis has a non-coherent integration that exceeds a detection threshold.

    摘要: A frequency domain diversity DVB receiver device includes multiple antenna ports for receiving radio signals, and radio signal processing circuits connected to the antenna ports that convert the received radio signals into digital samples. The digital samples from the different antenna ports time-share a front-end processor which processes the digital samples to provide time-domain symbols. The time-domain symbols are stored in time-domain symbol buffers according to which of the antenna ports the time-domain symbols are received. A fast fourier transform circuit then retrieves the time-domain symbols and converts them frequency-domain symbols, which are then stored one or more frequency-domain symbol buffers according to the antenna ports the corresponding radio signals are received. A diversity processor which combines the frequency-domain symbols from the frequency-domain symbol buffers.
