20110163548 | Earth's natural energy - Electrical power is produced by harnessing the natural energy from a deep well containing water or alcohol. A steel process tower having capillary characteristics is installed in the well. High pressure air enters the bottom of the well to create air bubbles rising in the well. The rising bubbles rotates a vertical helical propeller or turbine to produced the rotation movement for turning an electrical generator to produce the electrical output. Alternatively, separate sections and pressure reduction device may be provided in the tower to draw water to a water storage tower from which the water is directed to flow to a water wheel to rotate the electrical generator. | 07-07-2011 |

20130256745 | Deep Gate Trench IGBT - There are disclosed herein various implementations of an insulated-gate bipolar transistor (IGBT) with buried depletion electrode. Such an IGBT may include a collector at a bottom surface of a semiconductor substrate, a drift region having a first conductivity type situated over the collector, and a base layer having a second conductivity type opposite the first conductivity type situated over the drift region. The IGBT also includes a plurality of deep insulated trenches with a buried depletion electrode and at least one gate electrode disposed therein. In addition, the IGBT includes an active cell including an emitter adjacent the gate electrode, and an implant zone, situated between adjacent deep insulated trenches. The implant zone is formed below the base layer and has the first conductivity type. In one implementation, the IGBT may also include a dummy cell neighboring the active cell. | 10-03-2013 |

20120068888 | Flexible Antenna - A flexible antenna comprises a filmed layer, a flexible radiation conductor and a support member. The flexible radiation conductor has a crooked form and a feeder terminal. The filmed layer covers the upper surface of the flexible radiation conductor. The support member has a through-hole. The lower surface of the flexible radiation conductor is stuck to the upper surface of the support member. The feeder terminal is inserted through the through-hole to protrude from the lower surface of the support member. The flexible radiation conductor and the crooked feeder terminal thereof replace the conventional radiation conductor circuit layer and metallic contact terminal to overcome the problem that the conventional contact terminal damages the radiation conductor layer and protrudes the filmed layer. Further, the present invention integrates FPC and LDS technologies to enable the flexible radiation conductor to be arbitrarily stuck to complicated planes or complicated curved surfaces. | 03-22-2012 |

20120162018 | Thin-Film Antenna - A thin-film antenna comprises a plastic member, a flexible radiation conductor and a conduction member. The plastic member has an accommodation space. The flexible radiation conductor is disposed on one surface of the accommodation space. The conduction member has a contact terminal physically contacting the flexible radiation conductor. The flexible radiation conductor is embedded on one surface of the accommodation space of the plastic housing of a wireless communication device via a hot pressing process. The flexible radiation conductor can replace the conventional complicated rigid metallic radiation conductor to reduce thickness of products. The conduction member has a conductive metallic thimble for conducting electric signals, which can prevent the thin-film radiation conductor from protruding or breaking. The superior pliability and bendability of the flexible radiation conductor enables the flexible radiation conductor to integrate with an arbitrary surface, such as a complicated surface or a curved surface. | 06-28-2012 |
20120162041 | Monofrequency Antenna Integrated with Coaxial Feeder Cable - A monofrequency antenna integrated with a coaxial feeder cable comprises a first conductor, a second conductor and a feeder cable. The feeder cable includes a coating layer, an outer wire, an insulating layer and a central wire. The coating layer is formed on the outmost surface of the feeder cable. The outer wire is formed on the inner surface of the coating layer, extends in two opposite directions, and connects with the second conductor. The insulating layer is formed on the inner surface of the outer wire and extends in two opposite directions. The first conductor is formed on the inner surface of the insulating layer and extends along one direction. The central wire is formed on the inner surface of the insulating layer and extends along a direction opposite to the direction along which the first conductor extends. The present invention simplifies antenna structure and promotes transmission efficiency. | 06-28-2012 |
20120169544 | Multi-Frequency Antenna - A multi-frequency antenna comprises a first conductor, a second conductor, a grounding member, and a third conductor. The first and second conductors are respectively arranged on a first plane and a second plane. The grounding member is arranged on a third plane existing between the first and second planes. The third conductor is connected with the first conductor and arranged on the first plane also. The first and third conductors are respectively coupled to the radiation signals of the second conductor to form a first path and a second path. The first path and the second path have a phase difference of 180 degrees. The present invention features the additional third conductor. The third conductor and the first conductor are coupled to the radiation signals of the second conductor to generate opposite-phase signals. Thus are counterbalanced the interferences among the antenna systems of an identical frequency band. | 07-05-2012 |
20120169564 | Antenna With Improved Holed System Ground Plane - An antenna with an improved holed system ground plane comprises a substrate, a radiation conductor member, a grounding member and a system ground plane. The radiation conductor member is arranged on the surface of the substrate. The grounding member is arranged on one edge of the substrate. The radiation conductor member is connected with the grounding member. The system ground plane is connected with one side of the grounding member. The system ground plane has at least one arbitrary-shaped hole. A radiation-enhancing filler is disposed in the arbitrary-shaped hole. The present invention solves the conventional problems that the system ground plane is drilled or cut to accommodate components and IC chips, keep away from wiring routes and avoid protrusions on the appearance, via disposing radiation-enhancing fillers in the arbitrary-shaped holes. Thereby is kept integrality of the system ground plane and promoted omnidirectionality of signal transmission. | 07-05-2012 |

20120206359 | POINTING DEVICE WITH SOLID-STATE ROLLER - A solid-state roller on a pointing device with enhanced features. The solid-state design described herein allows the sensor to be placed on any shape of surface, such as one that has curvature in two directions. In one embodiment, a trench or downward curve contains sensors for detecting finger movement. The user's finger can thus bend about a knuckle in a curved motion to activate the sensor, requiring little or no movement of the finger up and down. The solid-state sensors can be of one of a number of designs. In one embodiment, multiple electrodes are contacted by a finger as it moves. Each electrode is coupled to a capacitive detection circuit, for detecting the change in capacitance as the electrode is contacted by the finger. | 08-16-2012 |
