    • Systems and methods using the same to achieve a camera having precise timing of a camera shutter, which can be used also for a controllable aperture, are disclosed. The aperture can be controlled continuously and can therefore be used for video cameras. The shutter system is controlled by a feedback loop. The shutter blades are moved by at least one linear motor, a position sensor senses the actual position and speed of the blades. The movement of the blades can be stopped any time to get an aperture desired. For capturing an image in a first step a global reset is opening (activating) every pixel of the image sensor after the shutter is opened. In order to achieve a short active light exposure time (below 1 ms), after the global reset, the mechanical shutter invented closes rapidly after a defined active light exposure time. An active light exposure time is the time span between the image sensor is activated and the mechanical shutter is closed. In order to achieve a precise timing the shutter of the present invention uses electronic control and a feedback loop to control the actual position of the shutter.
    • 公开了使用该相机的系统和方法来实现可用于可控孔径的相机快门的精确定时的相机。 可以连续控制光圈,因此可用于摄像机。 快门系统由反馈回路控制。 快门叶片由至少一个线性马达移动,位置传感器感测叶片的实际位置和速度。 可以随时停止叶片的运动以获得所需的孔。 为了在第一步骤中拍摄图像,在快门打开后,全局重置将打开(激活)图像传感器的每个像素。 为了实现短的主动曝光时间(低于1 ms),在全局复位后,发明的机械快门在定义的有源曝光时间后快速关闭。 主动曝光时间是图像传感器被激活并且机械快门关闭之间的时间跨度。 为了实现精确的定时,本发明的快门使用电子控制和反馈回路来控制快门的实际位置。

    • A system to stabilize images of a digital camera adjusting to unintentional movements of the camera during capture of an image has been achieved. A gyroscopic sensor senses any movement of a camera by angular speed detection and via an electronic regulator at least two linear motors move an x-y table, carrying an optical sensor or a lens barrel of the camera, in a way to adjust the optical sensor to these movements. Position sensors, as e.g. sensors integrated in the linear motors, capacitive sensors, inductive sensors, or Hall sensors, sense the actual position of one or more movable plates of the x-y table and feed it back to the regulator. The movable plates of x-y table are guided by a multitude of rolling elements, e.g. ball bearings.

    • Systems and methods by which voice/data communications may occur in multiple modes/protocols are disclosed. In particular, systems and methods are provided for multiple native mode/protocol voice and data transmissions and receptions with a computing system having a multi-bus structure, including, for example, a TDM bus and a packet bus, and multi-protocol framing engines. Such systems preferably include subsystem functions such as PBX, voice mail and other telephony functions, LAN hub and data router or switch functions. In preferred embodiments, a TDM bus and a packet bus are intelligently bridged and managed, thereby enabling such multiple mode/protocol voice and data transmissions to be intelligently managed and controlled with a single, integrated system. In particular, systems and methods for generating required telephony voltages directly on station cards, rather than on the basis of a large, central ringing or other power supply that supply such telephony voltages to each of the station cards, are disclosed. In accordance with the present invention, a plurality of station cards are provided in the telephony or communications system. One or more DC power supplies provide a source of DC voltage, such as 12 volts, to each of the station cards. The station cards are coupled to a processor of the system. The station cards may support a plurality of analog and/or digital telephony devices, such as telephones facsimile, voice mail, recording, speakerphone, conferencing or other type telephony devices.
