摘要： A method and pre-corrector for correcting signals in radio frequency links are provided. The method comprises: obtaining, in a time division order, a set of pre-distortion vectors for the respective radio frequency links by using one and the same set of pre-distortion vector obtaining means based on difference in arrival time of cyclic delay frames in the respective radio frequency links of a multiple input multiple output (MIMO) system; and correcting a subsequent signal in the respective radio frequency links by using the set of pre-distortion vectors corresponding to that radio frequency link. With the present invention, it is only required to scan a frame header once to generate an error vector table for the input signal across the entire dynamic range of power. The device can be reused by utilizing the cyclic delay frame structure, so as to achieve high linearity of a radio frequency header.

摘要： The invention discloses an antenna, which comprises a reference ground, a first radiation branch and a second radiation branch. The reference ground comprises a first grounding point and a second grounding point; the first radiation branch is connected to the reference ground via the first grounding point; the second radiation branch is connected to the reference ground via the second grounding point; wherein a slot is formed between the first radiation branch and the second radiation branch, and a distributed capacitance for coupling a signal is formed by coupling the first radiation branch and the second radiation branch via the slot; a connecting point is a feeding point via which one end of the second radiation branch for coupling the signal is connected to a radio frequency (RF) feed line, the feeding point arranged between the first grounding point and the second grounding point. The antenna of the present invention has advantages as follows: since a coplanar wave-guide coupling structure is used between the antenna resonant branches, which is equivalent to a capacitance loading, and a field loaded by the distributed capacitance is mainly concentrated in the air, thus a power loss caused by a resistor in a device after a lumped parameter capacitor is loaded is avoided. Therefore, the resonant frequency of the antenna and the size of the antenna are reduced.

摘要： The user wearable devices are configured to allow attendees of events to exchange their information upon a simultaneous input into their respective device. The simultaneous inputs initiate a verification that the two users are registered for and present at the same event before initiating a pairing through single direction short range antennas. The simultaneous inputs can also verify whether the two users are facing one another and an appropriate distance apart to coordinate the simultaneous input.

摘要： In a 3D free space micromirror device, a mirror plate is joined with actuators through flexible springs where the other ends of the actuators have fixed support on the substrate. Single crystal silicon and aluminum are used as bi-morph materials with silicon dioxide providing electrical isolation between the two. Thickness variation in the microstructure is achieved by two-step p-n junction formed in a p-type substrate. Thick and thin n-silicon layer formation and DRIE cut mechanisms are employed in such a way that all the thick and thin silicon components of the structure are released simultaneously avoiding overetch which can be detrimental to the thin flexural springs. Working prototypes of the device have been found suitable for any optical switching array architecture where deflections up to 10 degrees are required.
