Abstract: A data recommendation method is described. A first label set corresponding to multimedia data can be acquired. At least one second label set each corresponding to one of at least one to-be-recommended data can be acquired. Each second label set can include at least one label each representing a content attribute of the respective to-be-recommended data. A set similarity between the first label set and each of the at least one second label set can be determined according to label positions in the label tree. Target recommendation data matched with the multimedia data can be determined from the to-be-recommended data set according to the set similarity between the first label set and each of the at least one second label set.

Abstract: A 3D head-up display system and a method for 3D head-up display are disclosed. The 3D head-up display system comprises: a signal receiving module configured to receive a signal; a signal processing module configured to receive and process the signal received by the signal receiving module to generate a left-eye signal and a right-eye signal; a left head-up display device configured to receive the left-eye signal and generate a left-eye image; a right head-up display device configured to receive the right-eye signal and generate a right-eye image; a left optical system configured to project the left-eye image generated by the left head-up display device; and a right optical system configured to project the right-eye image generated by the right head-up display device.

Abstract: A method and apparatus for performing time synchronization and an OFDMA receiver thereof are provided. The method preferably includes performing a differential phase correlation in a frequency domain based on one received sequence and one reference preamble and detecting an integer frequency offset based on a result of the differential phase correlation. The method and apparatus advantageously enable the use of one OFDM symbol to estimate ICFO and the use of a simple method to facilitate ICFO detection. Moreover, the performance of the integer frequency offset estimation becomes more robust in high noise and time-variant fading channels, with reduced hardware complexity.

Abstract: A method and apparatus for time synchronization and an OFDMA receiver thereof are provided. A preamble timing is obtained by a two-stage correlation in a time domain between a sequence of a received symbol and a reference preamble. The two-stage correlation is further simplified to perform a conjugate multiplication between a one-stage correlation and its correspondingly delayed result. A preamble boundary is adaptively determined by a peak value based on a result of the two-stage correlation. In this way, the time synchronization is achieved with a robust performance in a low SNR, high frequency offset or large delay spread fading channel.

Abstract: A method for testing characteristics of a communication device that includes a plurality of modules using a test fixture includes the steps of connecting the communication device to the test fixture, determining if tests to be performed on the plurality of modules can be simultaneously performed, performing the tests to be performed on the plurality of modules for any tests that are determined can be simultaneously performed, calculating a numerical value for each of the plurality of modules if it is determined that the tests to be performed cannot be simultaneously performed, selecting one of the tests based on the calculated numerical value, and performing the selected one of the tests based on the calculated numerical value and suspending the test or tests on the remaining modules of the plurality of modules other than the selected one of the tests.

Abstract: A method of establishing a one-way communication session from a first device to a second device includes transmitting initiation data to the second device to establish the one-way communication session, transmitting communication data to the second device, and terminating the one-way communication session. The initiation data causes the second device to receive the communication data and prevents the second device from transmitting communication data to the first device until after the one-way communication session has been terminated.

Abstract: Multi-media Memory Card (MMC) devices, Secure Digital (SD) devices, and Secure Digital Input Output (SDIO) devices connected to a single host controller with signals multiplexed to allow simultaneous activation of more than one device at a time.

Abstract: The specification describes PDA (SD/MMC) devices and PDA cards wherein the substrate on which the PDA components are mounted comprises two tiers. Components with a high profile are mounted on the lower tier, and devices with normal or low heights are mounted on the upper tier. The upper tier is contained in the portion of the card conforming to, for example, the 1.4 mm SDA standard thickness, while the lower tier is formed in the portion of the card that allows a larger thickness, for example SDA standard thickness 2.1 mm.
