A DC level of the S-parameter rational function is compensated to generate a compensated S-parameter rational function. | 01-19-2012 |
20120025857 | MANIPULATOR OF ROBOT - An exemplary manipulator of a robot includes a fastening seat defining two guiding grooves, a driving mechanism disposed on the fastening seat, two transmitting plates respectively received in the two guiding grooves and cooperating with the driving mechanism, and two detecting bars each fixedly connecting with a corresponding transmitting plate. A detecting pin is fixed on each of the detecting bars. Under a driving action of the driving mechanism on the transmitting plates, the transmitting plates are activated to slide in the guiding grooves to cause the detecting bars to move close to or apart from each other, whereby a distance between the two detecting pins is automatically regulated. | 02-02-2012 |
20120029887 | COMPUTING DEVICE AND METHOD FOR ANALYZING SCATTERING PARAMETERS PASSIVITY - A computing device and a method measures scattering parameters (S-parameters) values at ports of a circuit at different signal frequencies, and creates a non-common-pole rational function of S-parameters by applying a vector fitting algorithm to the S-parameters.

20120095716 | ELECTRONIC DEVICE AND METHOD FOR CONTROLLING MODULATIONS OF MULTIPLE-INSTRUMENTS AND SENSORS - A method for modulating multiple-instruments and multiple-sensors using an electronic device. The electronic device controls an instrument to measure the working parameters of an object, and controls a sensor to detect the working temperature of the object. By comparing the working parameters against a predefined range, and comparing the working temperature against a predefined temperature value, the electronic device determines whether the instrument and the sensor need to be modulated. If any of the working parameters is not within the predefined range or if the working temperature is greater than the predefined temperature value, the electronic device controls the instrument and the sensor to be modulated by using a modulation transfer function and a predetermined direction. | 04-19-2012 |
