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.

The present invention provides a method for real-time receiving of mails, comprising: step 1 of a control block controlling a wireless block to receive the mails from a mail server and storing them in a storage block when a computer is in a sleep, suspend or shutdown mode; and step 2 of the mails stored in the storage block being synchronized to a mail program of the computer after the computer is turned on. It is possible to update mails in a real-time manner when the computer is in a sleep, suspend or shutdown mode by the present invention with simple device structure. The present invention also supports mails pushed by the mail server, and has the advantages of time saving, power saving and safety.

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.

In some aspects, the present invention provides systems, methods and devices for an event attendee to automatically self-register for an event, self-generate personal information on a wearable device, display local merchant information, and exchange personal contact information with other event attendees. For example, an event attendee may press RSVP on a mobile device and then press a button on a wearable device to show his or her name, employer, personal interests, and local merchant logos or special offers. He or she can also press the button of the wearable device to transmit the personal contact information to another individual he or she is talking to.
摘要:
To provide a control system of a stereo imaging device that is able to obtain a stereo image, which can be viewed stereoscopically, even when relative-position relationship of a pair of imaging units is unknown. A control system of a stereo imaging device includes a pair of imaging units, an error calculation unit and a control unit. A pair of the imaging units has a digital or analog degree of freedom so as to be able to control at least a yaw, pitch, roll and zoom factor, and can capture video frames using imaging elements. The error calculation unit uses each of images captured by a pair of the imaging units to calculate a rotating error and zoom error of each imaging unit on the basis of a difference from a predetermined standard convergence model of each imaging unit.

An equipment (200) for controlling an air system of a diesel engine, comprises an operation condition acquiring device (202), an objective flow determining device (204) and a signal generating device (206). The operation condition acquiring device (202) is used to acquire actual operation condition parameters of the diesel engine. The objective flow determining device (204) is used to determine objective flow parameters on the basis of the actual operation condition parameters from the operation condition acquiring device (202), through a non-linear physical model which characterizes the air system. The signal generating device (206) is used to generate signals for controlling an EGR system and a turbocharge system on the basis of the objective flow parameters from the objective flow determining device (204). A method for controlling an air system of a diesel engine and a computer program medium recording the computer program code for performing the method are also disclosed.
