  • Publication number: 20120123976
    Abstract: Methods and systems for object-sensitive image searches are described herein. These methods and systems are usable for receiving a query for an image of an object and providing a ranked list of query results to the user based on a ranking of the images. The object-sensitive image searches may generate a pre-trained multi-instance learning (MIL) model trained from free training data from users sharing images at websites to identify a common pattern of the object, and/or may generate a MIL model “on the fly” trained from pseudo-positive and pseudo-negative samples of query results to identify a common pattern of the object. As such, the user is presented with query results that include images that prominently display the object near the top of the results.

  • Patent number: 7944089
    Abstract: An uninterruptible power supply module is provided. The uninterruptible power supply module comprises an input terminal, a direct-current voltage source, a control module, a control arm-bridge module, an inductive element, a power source selection switch, and a switch element. The switch element is turned on before the power source selection switch is connected to the inductive element so that the direct-current voltage supplied by the direct-current voltage source is modulated by the control arm-bridge module to generate an output alternating current voltage to the load. And the switch element is turned off, i.e. not conducting electricity, after the power source selection switch is connected to the inductive element and the direct-current voltage source. Thereby, the use life of the power source selection switch element and the reliability of the uninterruptible power supply module are both increased.

  • Patent number: 6039037
    Abstract: A power cutter is disclosed whose dust suction-discharge fan is driven to rotate at a high speed to thereby attain sufficient dust suction-discharge performance, and which can be constructed relatively compactly in size as a whole at a reduced cost. The power cutter includes two rotating operative components (30, 50) driven by a prime mover (5) and a centrifugal clutch (10) operatively connected to the output shaft (7) of the prime mover (5) for rotationally driving the two rotating operative components (30, 50). The centrifugal clutch (10) includes a clutch drum (11) composed integrally of a small diameter pulley portion (21) and a large diameter pulley portion (22). Belt-type drive trains (15A, 16A and 17A, 18A) transmit the rotational drive force to the rotating operative components (30, 50), respectively.

  • Patent number: 6014811
    Abstract: A power cutter is disclosed which is capable of selectively changing the discharge direction of dust discharged from a dust discharge port of a dust suction-discharge fan and, hence, which is capable of optimally adjusting the dust discharge direction according to the operational condition or operational position of the power cutter. An elbow-shaped auxiliary discharge pipe is coupled to the dust discharge port of the dust suction-discharge fan in such a manner that it can be turned and kept at any turned position. In addition, a belt tensioning clutch is provided to permit selective connection and disconnection of the belt drive transmission between the power source and the dust section-discharge fan. This permits fan operation to be interrupted when not needed.
