20150071306 | TIME AND FREQUENCY DIVERSITY MODULATION SYSTEM AND METHOD - A method of encoding a set of L bits for transmission on a transmission band through a transmission medium is provided, wherein L is a positive integer that is greater than 1. The method includes: mapping, via a mapping component, the L bits into M symbols; dividing, via a first dividing component, the transmission band into sub-bands; allocating, via an allocating component, the M symbols to individual sub-bands, respectively, for transmission at a first time; and allocating, via the allocating component, the M symbols to different individual sub-bands, respectively, for transmission at a second time. | 03-12-2015 |
20150098515 | AUTOMATIC GAIN CONTROL FOR POWER LINE COMMUNICATION - A system includes an analog front end (AFE) unit to be coupled to a power line network, and a controller coupled to the AFE unit. More specifically, the AFE unit is to receive a packet signal from the power line network wherein, based on a first gain parameter, the AFE unit is to amplify the received packet signal. The controller is configured to calculate a root-mean-square (RMS) power of the amplified packet signal. Further, the AFE unit is to calculate a second gain parameter based on the calculated RMS power of the amplified packet signal and the first gain parameter, wherein the second gain parameter is to be used to amplify the received packet signal instead of the first gain parameter. | 04-09-2015 |

20140161727 | OPTICAL-IMAGING PROBE FOR DETECTING SENTINEL LYMPH NODES WHICH CONTAINS A COMPOSITE OF POLY-GAMMA-GLUTAMIC ACID AND AN OPTICAL-IMAGING DIE - The present invention relates to an optical imaging probe for detecting a sentinel lymph node, which contains a complex of poly-gamma-glutamic acid and an optical imaging dye, and more particularly to an optical imaging probe for detecting a sentinel lymph node, which contains a poly-gamma-glutamic acid/optical imaging dye complex that, when injected subcutaneously in vivo, remains in the sentinel lymph node for a relatively long period of time and has a low tendency to migrate to other lymph nodes. The present invention provides a poly-gamma-glutamic acid/fluorescent dye complex, which contains no radiopharmaceutical and is harmless to the human body. The use of the poly-gamma-glutamic acid/fluorescent dye complex makes it possible to accurately detect the position of a sentinel lymph node in real time without concerns about radioactive contamination. | 06-12-2014 |

20150267943 | MAGNETIC REGENERATOR UNIT AND MAGNETIC COOLING SYSTEM WITH THE SAME - A terminal may be provided with a magnetic regenerator unit using a magnetocaloric effect of magnetocaloric materials and a magnetic cooling system having the same. By a circular magnetic regenerator structure capable of evenly flowing heat transfer fluid and magnetic field and the flow of the heat transfer fluid being changed in the same way, and a magnetic band having a relative permeability, similar to a relative permeability of the magnetic regenerator, high efficiency of a flux generator may be obtained while reducing torque of a rotator. Power consumption for driving may be reduced due to the reduction of the cogging torque, and the magnetic band may be manufactured at a low cost by using inexpensive iron powder. | 09-24-2015 |
