Title: Architecture d'émetteur-récepteur de bande ultra large et procédé
Inventor: PRIMO HAIM
IPC: H04J14/02
Filed: 2008-12-30
Abstract: Selon la technologie connue, la consommation d'énergie d'émetteur-récepteur de bande ultra large est inefficace et trop élevée. Ce problème a été résolu grâce à la présente invention qui propose un circuit innovateur d'émetteur récepteur de bande ultra large, pouvant être utilisé pour une réception OFDM basée sur préambule ou basée sur symboles pilotes. Dans IEEE P802.15-03/268r3, il est rapporté que la consommation d'énergie de récepteur OFDM de bande ultra large à 480Mbits/seconde, lors de l'utilisation de la méthode numérique classique, est de 323mwatts pour 130nm, et de 236mwatts pour 90nm. On a observé que l'utilisation du même récepteur à l'aide du récepteur OFDM selon la présente invention, opérant à 480Mhz, consomme environ 40mwatts. Il est évident qu'en termes de consommation d'énergie, l'utilisation du récepteur OFDM selon la présente invention est inférieure de huit fois à la plus faible consommation connue de nos jours d'un circuit récepteur OFDM de l'art antérieur.

Title: Temperature activated shut off mechanism
Inventor: MATKAR JAYANT
IPC: F23N5/02
Filed: 2013-03-12
Abstract: A temperature activated shut off mechanism for a valve is disclosed. The temperature activated shut off mechanism includes a plunger, a spring, a nut, a fusible block and a closing element. The spring configures a compressed and a de-compressed configuration. The closing element prevents flow of gas out of the temperature activated shut off mechanism in the de-compressed configuration of the spring. In a gas flow configuration of the temperature activated shut off mechanism, the spring is in compressed configuration between the inner surface of the valve and the nut and the gas flows out of the temperature activated shut off mechanism. In a gas blocking configuration, when temperature exceeds a predetermined limit then the fusible block melts causing the spring to form the de-compressed configuration and thereby activating the closing element to prevent flow of gas out of the temperature activated shut off mechanism.

Title: 遅延疎行列
Inventor: NIITSUMA HIROTAKA
IPC: G06F17/16
Filed: 2018-01-18
Abstract: メモリに収まりきらない行列データが出現する計算をメモリに収まるようにする解決手段として行列を生成する手順を、より少ないメモリで表現し、 行列の値が必要になったら、毎回その手順を遅延評価して値を計算しなおすことでメモリ使用量を減らす。 Sparse Matrixのcorrespondence analysisで特に有効で、Sparse Matrixを正規化する過程でできてしまう Dense Matrixをメモリに保存しないでSparse Matrixの状態のままで計算ができる。 このcorrespondence analysisで計算するSingular Value Decompositionとして randomized singular value decompositionを利用すると，基になる行列と任意の行列との積だけを遅延評価で計算できるように技術するだけで良いため、 必要となるメモリーは基になるSparse Matrixとほぼ同程度のメモリーが必要なだけにできる。 従来はこのSingular Value Decompositionの計算の過程でDense Matrixへの変換を行うことでメモリーを大幅に必要としていた。

Inventor: SONG JIN-WOO
IPC: G06Q50/00
Filed: 2010-02-05
Abstract: The present invention relates to a content providing system capable of sharing an application. Since a conventional content providing system and the contents are based on various heterogeneous platforms, the content providing application also must be heterogeneous depending on the platform. Problems related to copyright protection and profit frequently occur because contents must be uploaded to a system provider's server to be provided, and costs can increase because the system provider must have a system for storing contents. Additionally, a content provider is frequently inconvenienced because contents must be adjusted to the requirements and types of a system in order to be uploaded. The present invention enables provision of Web content and multimedia content such as movies, games, shopping, and reservations, regardless of a client's device platform, which corresponds to various platform-based clients such as a PC, a PDA, a set-top box, or a mobile device. Thereby, the present invention provides the system which can secure and charge for content properly while properly connecting the content provider with the system provider.

Inventor: KWON KI YOUNG
IPC: B01J23/44
Filed: 2010-04-13
Abstract: The present invention relates to a cyclic Pd nanostructure and to a Pd nanostructure catalyst for hydrocarbon compound synthesis. More particularly, the present invention relates to a cyclic Pd nanostructure, wherein a cyclic Pd nanostructure with a size of 10 to 300 nm is obtained through reassembling cubic Pd nanoparticles by controlling the reduction rate of palladium chloride (PdCl 2 ) to cubic Pd nanoparticles using voltage and current, and to a Pd nanostructure catalyst for hydrocarbon compound synthesis. The above-described present invention is highly effective in various applications such as a Pd nanostructure catalyst for hydrocarbon compound synthesis, which synthesizes hydrocarbon compounds by reacting hydrogen and carbon dioxide generated by air pollutant discharge reduction or elimination systems in coal refinery facilities, thermal power plants or cement-processing plants, due to the unique characteristics of the cyclic Pd nanostructure such as high energy, large surface area, chemically adjustable physical properties, and high structural stability. In addition, since the nanostructure can be simply formed under low-energy conditions at room temperature and at atmospheric pressure, it is possible to manufacture a mass-producible high-purity and ultra-precision Pd nanostructure.
