  • Publication number: 20150163518
    Abstract: The present disclosure provides an electronic device and an information processing method. The electronic device comprises: a processor which comprises N processing units to process data and perform data input and output; a data processing interface coupled to Q processing units among the N processing units, which compresses raw data received from the Q processing units to obtain compressed data; and a memory coupled to the data processing interface, which receives and stores the compressed data, where N?1 and 1?Q?N.

  • Publication number: 20140225780
    Abstract: Multiple time-difference-of-arrival units, each having two or more receiver antennas can be used to determine a location of a target transmitter without synchronizing or connecting together the units. Specifically, a clock on each unit can be used to determine a difference of arrival of radio-frequency signals amongst antennas on the units. Each unit's clock can be asynchronous with the clocks on the other units. Target estimation can therefore be achieved easily with limited wiring and the problems associated with synchronization can be reduced or eliminated. The multiple time-difference-of-arrival units can be used in indoor, outdoor (or a combination thereof) applications.

  • Patent number: 8715607
    Abstract: Metallic CNTs and semiconducting CNTs are efficiently separated from a CNT mixture of these CNTs, and semiconducting CNTs are separated by structure by using a method that enables separation in high yield in a short time period while conveniently enabling mass processing and automatic processing with inexpensive equipment. Multiple columns charged with gel are connected in series, and excess amounts of a CNT dispersion is passed through the columns to adsorb only the CNTs of a specific structure on the columns. The CNTs are then eluted with an elution to separate CNTs of different structures with high accuracy. The present technique represents a method that conveniently enables mass processing and automatic processing at high yield in a short time period with inexpensive equipment.

  • Patent number: 8512668
    Abstract: To provide a method for separating metallic CNT and semiconducting CNT by treating a CNT-containing gel or a CNT dispersion as combined with a gel, according to a physical separation means to thereby make semiconducting CNT exist in gel and metallic CNT exist in solution, in which the semiconducting CNT adsorbed by gel are collected in a more simplified manner not dissolving the gel. A CNT-containing gel or a CNT dispersion combined with a gel is treated according to a physical separation means of a centrifugal method, a freezing squeezing method, a diffusion method or a permeation method, to thereby make semiconducting CNT exist in gel and metallic CNT exist in solution so that the metallic CNT and the semiconducting CNT are separated from each other, and further, a suitable eluent is made to react on the gel that adsorbs semiconducting CNT to elute the semiconducting CNT from the gel.

  • Patent number: 7286505
    Abstract: This relates to a method and system for channel element allocation for wireless systems. More particularly, the method and system are directed to channel element allocation based on voice call equivalence, bit load, and call quantum weight for multimedia wireless systems (e.g. 3g UMTS systems).
