Method for reducing interference powers and corresponding acoustic system
The object is to improve the action of a directional microphone in real acoustic environments. To do this, it is envisaged that the interference powers in a directional microphone with three microphones are reduced in that a first and a second microphone signal are adaptively filtered with respect to a first direction, with a direction-determining first parameter being adapted in such a way that the summation of interference powers is reduced.

The two parameters are different from each other. This makes it possible, even in real environments, to suppress two interference sources from different directions with one second-order directional microphone. |

Neutron-driven element transmuter
A material is exposed to a neutron flux by distributing it in a neutron-diffusing medium surrounding a neutron source.

It may also be used to efficiently transmute long-lived radioactive wastes, such as those recovered from spent nuclear fuel. The use of heavy elements, such as lead and/or bismuth, as the diffusing medium is particularly of interest, since it results in a slowly decreasing scan through the neutron energy spectrum, thereby permitting very efficient resonant neutron capture in the exposed material. |

Radio communication system, receiver, receiving method, transmitter, transmitting method, and device for and method of calculating delay times for multi-carrier transmission
Multi-carrier transmission is performed without inserting a repetitive signal into guard interval periods. A transmitter provides guard interval periods by using a null signal to save transmission power and prevent the deterioration of the SN ratio. Delayed waves at the head of each received symbol cause high-frequency waves to occur and carriers to interfere with one another. Accordingly, a receiver adds a component following each received symbol to a delayed-wave component at the head of the received symbol. As a result, the delayed-wave component at the head of the received symbol and the added component become continuous in wave form and subcarriers do not interfere with each other. |

Systems and methods for indicating buffered data at an access point using a traffic indication map broadcast
Stations in standby mode periodically wake up to check for buffered data at the access points.

According to the display voltage at a drain of a TFT in the pixel, an average of display voltages of positive and negative polarities is obtained in two frame times. The average value is regarded as a common voltage supplied to every pixel in an active pixel region in the display panel. Thereby, the problem of a drift of a feed-through voltage (ΔVD) of a scan voltage due to an RC delay of a parasitic-capacitance and a parasitic-resistance on the scan line can be avoided. Further, the gray-level accuracy of every pixel in the active pixel region can be improved, and the flicker-noise of the display-panel can be reduced, thus significantly promoting the display quality of the LCD. |

Inductance enhanced rotary traveling wave oscillator circuit and method
An inductance enhanced rotary traveling wave oscillator is disclosed. Portions of the transmission line conductors are increased in length and run in parallel. Because the currents in these portions travel in the same direction, the inductance of these inductors is increased.

Increased impedance leads to lower power, higher Q, and lower phase noise for the oscillator. Additionally, the folded nature of the transmission line conductors permits a longer length of transmission line conductors to be routed in a smaller area. The folded nature also permits placement of the devices to take into account their switching delays. A folded circular version of the oscillator is possible, leading to improved access to phase taps on the oscillator. |

Thermoset nanocomposite particles, processing for their production, and their use in oil and natural gas drilling applications
Thermoset polymer particles are used in many applications requiring lightweight particles possessing high stiffness, strength, temperature resistance, and/or resistance to aggressive environments. The present invention relates to the use of two different methods, either each by itself or in combination, to enhance the stiffness, strength, maximum possible use temperature, and environmental resistance of such particles.

In general, its main benefits are the enhancement of the maximum possible use temperature and the environmental resistance. The other method is the incorporation of nanofillers, resulting in a heterogeneous “nanocomposite” morphology. In general, its main benefits are increased stiffness and strength. Nanofiller incorporation and post-polymerization heat treatment can also be combined to obtain the benefits of both methods simultaneously. The present invention relates to the development of thermoset nanocomposite particles. It also relates to the optional further improvement of the heat resistance and environmental resistance of said particles via post-polymerization heat treatment.

A chip is disposed on the thin metal plate, and a plurality of bonding wires for electrically connecting the chip to the second protrusion part and the second protrusion part to the third protrusion parts is formed. An upper encapsulant and a lower encapsulant are formed on the upper surface and the lower surface of the thin metal plate respectively. The lower encapsulant has a plurality of recesses for exposing a portion of the thin metal plate at locations where the first protrusion part, the second protrusion part and the third protrusion parts are connected to one another. Finally, the thin metal plate is etched by using the lower encapsulant as an etching mask. |
