20110005499 | FUEL INJECTION DEVICE FOR AN INTERNAL COMBUSTION ENGINE, AND ASSOCIATED METHOD - A fuel injection device and associated method are provided. An injector body defines an axial bore and has a nozzle exit extending into the combustion chamber. The injector body receives fuel within the bore and channels the fuel through the nozzle exit into the combustion chamber. A flow rate control member is movably disposed within the injector body bore and is actuatable by a first actuator to move with respect to and to interact with the nozzle exit to control a flow rate of the channeled fuel. A pintle member is movably disposed within a flow rate control member bore and is actuatable by a second actuator, independently of the flow rate control member, to move with respect to the flow rate control member and to interact with the nozzle exit to control a spray angle of the channeled fuel. The flow rate and spray angle are thereby independently controllable. | 01-13-2011 |

20160125381 | Secure Wireless Network-Based Activation for Table-Side Information and Point-of-Sale Devices - A new terminal is seamlessly and securely integrated to an existing (primary) Wi-Fi network within an operating environment at a restaurant location. The location includes a data management server (DMS) for managing the local operations of devices operating there. The device being installed at the location is auto-configured into the primary Wi-Fi network by being provided with a default Wi-Fi profile that only enables the device to be activated on an activation Wi-Fi network also available at the location. Once the device activates to the Wi-Fi activation network, it requests activation onto the primary Wi-Fi network from a cloud-based data center. The data center requests an activation password from the local DMS. The local DMS generates an activation bundle, which is then returned and eventually instantiated on the device to complete the activation. Once activated, the device updates its Wi-Fi profile to now executed on the primary Wi-Fi network. | 05-05-2016 |

20090237517 | Optical module, camera, and mobile terminal device - An optical module, a camera, and a mobile terminal device are provided. The optical module includes a lens unit, a lens driving unit, a driving control unit, and a vibration sensing unit. The vibration sensing unit is configured to detect vibration/shaking of the optical module, the camera, or the mobile terminal device and transmit a detected signal to the driving control unit. The driving control unit generates a corresponding vibration/shaking compensation signal according to the detected signal of the vibration sensor, and performs a vibration/shaking compensation movement by driving the lens with the lens driving unit. The optical module is applied in the camera and the mobile terminal device. The present invention has not only an auto-focusing function, but also an added anti-vibration function, so as to overcome influences on image degradation resulted from vibration/shaking of the optical module, the camera, or the mobile terminal device. | 09-24-2009 |
20090244298 | Imaging device and image capture device - The invention discloses a imaging device, comprising an imaging module, used for optical to electrical signal conversion, which comprises at least a first imaging unit and a second imaging unit, the first imaging unit used for capturing an image, the second imaging unit used for detecting the movement of the image or the imaging device; a control and processing module, used for controlling the imaging module to output electrical signals, and for processing the electrical signal to generate and to output the motion signal and image signal. The invention also discloses an image capture device which uses the said imaging device. The imaging device can output the motion signal and the image signal simultaneously by adding the second imaging unit used for detecting the movement of the image or the imaging device; consequently better captured image quality can be obtained. Also, the structure can become simpler and the manufacture cost can be lower. | 10-01-2009 |
