  • Publication number: 20140204229
    Abstract: The present application is directed to a photo shooting control method and control device, the method includes: pairing with a mobile device, and building up a connection with the mobile device upon successful pairing, obtaining key pressing information, and generating a first control signal and a second control signal for transmitting to the mobile device according to the key pressing information. The first control signal or the second control signal controls the shutter release in the camera application of the mobile device for photo shooting. Either signal can be configured though USB or NFC connection by an external device so that the usage of the photo shooting control device can be extended to other applications including PowerPoint, Siri and smart home appliances.

  • Patent number: 8497611
    Abstract: An end-frame of an electro-dynamic machine includes a bearing housing defining an annular bearing cavity for rotatably supporting a rotor shaft about an axis. A support body is coupled to the bearing housing. The support body has a terminal end and a base end opposite the terminal end. The base end includes a first radial support surface having a first diameter, a second radial support surface having a second diameter, and an annular wall axially disposed between the first radial support surface and the second radial support surface. A radial extension extends radially from the support body adjacent the terminal end. A mounting member extends axially from the radial extension portion. The mounting member defines an aperture for receiving a BX fitting.

  • Patent number: 8287155
    Abstract: A device for simulating and/or attracting aquatic life forms is disclosed. The device includes an electromagnetic module with a dry battery that is activated when exposed electrodes of the dry battery are placed in contact with a common electrolyte, such as sea water. The dry battery generates gas bubbles and sound in an aquatic environment, which attracts the aquatic life forms. In further embodiments of the invention, the device includes one or more removable jackets with holes or vents that facilities a controllable release of the gas bubbles generated by the dry battery.

  • Publication number: 20110293968
    Abstract: The present invention is directed to a starch-based battery system. The starch-based battery system uses a rheological and replaceable starch gluten electrolyte that generates colloidal starch gel adhesive contacted with and/or attached on electrodes to generate current for powering electronic devices. The starch-based battery system that includes control circuit and standard cap module replaces a conventional dry cell battery or is integrated with electronic devices to power, for example, flash-light, lighting ornaments or magnetic actuated motion products and toys. In other embodiments of the invention, the starch-based battery system is integrated into a device for attracting aquatic life forms in an aquatic environment, wherein the starch-based battery powers a light source and/or sound source and also the starch gluten electrolyte acts as bait for attracting aquatic life forms within the aquatic environment.

  • Patent number: 8011857
    Abstract: The present invention describes an extraction system (100,100a) for expediting removal of a footing (105) that is embedded in a seabed or marine floor. The extraction system provides a supply of pressurized fluid (140) to a chamber from where the pressurized fluid exudes through porous members (122,122a, etc) located on the base (114) of the footing (105). When an uplifting force is applied to the footing (105) for its removal, the pressurized fluid (140) exudes out through the porous member (122,122a, etc.) to compensate or reduce suction induced beneath the footing, without fluidizing or channeling of the seabed soil, thereby expediting removal of the footing (105).

  • Patent number: 7898131
    Abstract: A motor including a stator, a first connector portion, a selector, and a second connector portion. The stator has a first winding arrangement configured for a first voltage and a second winding arrangement configured for a second voltage different from the first voltage. The first connector portion is selectively connectable to each of the first winding arrangement and the second winding arrangement. The selector is movable between a first position in which the first connector portion is connected to the first winding arrangement, and a second position in which the first connector portion is connected to the second winding arrangement. The second connector portion is electrically connected to a power supply and selectively engageable with the first connector portion to provide power to one of the first winding arrangement and the second winding arrangement.
