    • Some representative embodiments are directed to controlling access to a wireless medium using “credit” periods and “free” periods. During a credit period, credits are initially assigned to the stations and each station is repetitively polled as long as the station has credit remaining and data is available to communicate. During the free periods, stations are polled using a start-time fair queuing algorithm. By dividing the access to the wireless medium in this manner, real time applications may use the credit periods to prevent communication latency from deteriorating application performance. Specifically, the repetitive occurrence of the credit periods and the assignment of credits to the stations ensures that each station will communicate at least at a minimum data rate. Additionally, controlling access to the wireless medium in this manner prevents frame collisions and, thereby, increases network throughput.
    • 一些代表性的实施例涉及使用“信用”期和“自由”周期来控制对无线介质的访问。 在信用期间,信用卡最初被分配到电台,并且每个电台都被重复地轮询,只要电台有信用余额并且数据可用于通信。 在空闲期间,使用开始时间公平排队算法轮询站。 通过以这种方式分配对无线介质的访问,实时应用可以使用信用期来防止通信延迟降低应用程序性能。 具体来说,信用期的重复发生和对站的信用分配确保每个站将至少以最小数据速率通信。 此外,以这种方式控制对无线介质的访问防止帧冲突,从而增加网络吞吐量。

    • 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.
