20090009306 | OBSTACLE DETECTION APPARATUS - An obstacle detection apparatus for a vehicle is provided. The apparatus includes an ultrasonic sensor and a controller. The ultrasonic sensor detects a presence of an obstacle around the vehicle and a distance to the obstacle by transmitting an ultrasonic wave and receiving the ultrasonic wave reflected by the obstacle. The controller controls the ultrasonic sensor. The ultrasonic sensor includes an ultrasonic wave element. The ultrasonic wave element has multiple resonance modes. The ultrasonic sensor changes a directivity of the ultrasonic sensor by selecting one of the multiple resonance modes of the ultrasonic wave element in accordance with a command signal output from the controller. | 01-08-2009 |

20150369302 | FRICTION PLATE AND WET-TYPE MULTIPLE-DISC CLUTCH WITH FRICTION PLATE - The present invention provides a friction plate that takes more air into a lubricating oil on a friction surface so as to reduce the shear resistance force of the lubricating oil interposed between friction materials, thereby achieving significantly reduced drag torque at the time of idling, as compared with a conventional friction plate, and a wet-type multiple-disc clutch provided with the friction plate. The friction plate has a plurality of friction material segments circularly fixed on an annular core plate, wherein each of the friction material segments includes an oil groove having an opening that opens in the direction of an outer circumferential edge of the friction plate and an end portion that ends between an inner circumferential edge and the outer circumferential edge, oil passages in communication in the direction of the inner and the outer circumferential edges of the friction plate are provided among the friction material segments, and at least some of the oil passages have a first shape, the width of which in a circumferential direction decreases from the inner circumferential edge of the friction plate toward the outer circumferential edge thereof. | 12-24-2015 |

20120179799 | METHOD AND APPARATUS OF SELECTION INTERFACE BY QUEUE AND WORKLOAD FOR STORAGE OPERATION - A method selects an interface in a storage subsystem for processing storage operations, each interface associated with a corresponding processor. A management server has plural providers, each for executing storage operations on one of the processors via the corresponding interface. The method comprises: collecting information on status of each of the providers; based on the status of each provider, determining an operational characteristic of operation time as a function of a number of operational units for each provider; comparing the operational characteristics of the providers; for a given number of operational units in the storage operations to be processed, selecting from among the providers one provider which has the lowest operation time for the given number of operational units; and identifying the interface based on the selected provider to be used for executing the storage operations via the identified interface on the corresponding processor. | 07-12-2012 |
20120191929 | METHOD AND APPARATUS OF RAPIDLY DEPLOYING VIRTUAL MACHINE POOLING VOLUME - Exemplary embodiments provide rapid creation and deployment of virtual machines by reducing communication processes between virtual machine user and storage and server administrators. One embodiment is a method for deploying virtual machines of host computers. A storage subsystem provides a pool of pre-created virtual volumes in the storage subsystem prior to deploying the virtual machines, the pre-created virtual volumes having pre-copied images for the virtual machines. The method comprises: selecting one of the pre-created virtual volumes for deploying one of the virtual machines; calculating a volume size for the selected virtual volume based on a specified image size for data and OS image; resizing the selected virtual volume according to the calculated volume size; and requesting one of the host computers to deploy the virtual machine using the resized virtual volume. | 07-26-2012 |

20130230881 | METHOD AND APPARATUS FOR TESTING CARDIOTOXICITY AND EVALUATING CARDIOMYOCYTES - In the present invention, a cardiomyocyte cluster is disposed on a transparent substrate, and the quality of the cardiomyocytes is evaluated from the response of the cells to a forced pulsation stimulus applied to the cardiomyocytes. The cardiomyocyte cluster is disposed on the transparent substrate, and is exposed to the flow of a liquid containing an agent in a manner so that the agent acts on the cells, which configure a network. The extent of cardiac toxicity resulting from the agent is evaluated from measuring the fluctuations obtained from a comparison of adjacent cardiomyocytes of the network. | 09-05-2013 |
20140349332 | METHOD AND DEVICE FOR EXAMINING MYOCARDIAL TOXICITY AND EVALUATING CARDIOMYOCYTE - A method wherein a mass of cardiomyocytes is disposed on a transparent substrate and the quality of the cardiomyocytes is evaluated from the response of the cardiomyocytes to a forced pulsation stimulus that is applied to the pulsating cardiomyocytes. The mass of cardiomyocytes, which is disposed on the transparent substrate, is exposed to the flow of a drug-containing liquid in such a manner as to allow the drug to act on cells configuring a network. The level of cardiotoxicity caused by the drug is evaluated by measuring the fluctuations obtained from a comparison of adjacent pulsating cardiomyocytes of the network. | 11-27-2014 |

20100173351 | CARDIAC REENTRY MODEL CHIP AND APPARATUS AND METHOD FOR EVALUATING DRUG USING THE CARDIAC REENTRY MODEL CHIP - A chip has been developed that can accurately measure cell potential and cell morphology on a single cell basis. The chip also constitutes a cardiac model that comprises a closed loop whereupon cardiomyocytes and fibroblasts are suitably dispersed and arranged, and that can evaluate the effects of a drug thereon. An in vitro cardiac reentry model chip is fabricated by constructing a closed loop comprising cardiomyocytes and fibroblasts arrayed on transparent electrodes formed on a transparent substrate by using a constitution where single cells are enclosed in a specific spatial configuration. A pulse wave of a random cardiomyocyte or a specific cardiomyocyte is propagated on both sides of the loop, and the pulsation status of the cells in the loop is detected electrically. A drug is applied to this cardiac reentry model chip, and the benefit or toxicity of the drug to cardiomyocytes is evaluated by measuring the cell potentials of individual cells. | 07-08-2010 |
