    • A wireless communication device receives a message periodically broadcast by a wireless broadcast device placed within a location, and determines a type of the location and a broadcast period of the message. The wireless communication device sets a check period for periodically checking whether the wireless communication device receives the message, and checks if a present alert mode of the wireless communication device is suitable for the type of the location in a present check period. When the present alert mode of the wireless communication device is not suitable, the wireless communication device automatically switches the present tone mode to a new tone. When the wireless communication device does not receive the message within a next check period, the wireless communication device is determined as having left the location and automatically switched back to the present alert mode from the new alert mode.
    • 无线通信设备接收由放置在位置内的无线广播设备周期性广播的消息,并且确定该消息的位置类型和广播周期。 无线通信装置设置用于周期性地检查无线通信装置是否接收到消息的检查周期,并且检查无线通信装置的当前警报模式是否适合于当前检查周期中的位置的类型。 当无线通信设备的当前警报模式不合适时,无线通信设备自动将当前音调模式切换到新的音调。 当无线通信设备在下一个检查周期内没有接收到消息时,无线通信设备被确定为已经离开该位置并且从新的警报模式自动地切换回当前警报模式。

    • A surveillance camera that includes a device for capturing video signals and that converts the video signals to optical signals. The surveillance camera has a first component with a first aperture and a second component with a second aperture. The second component engages the first component such that the first component rotates relative to the second component. The surveillance camera has a first optical component that extends through the first aperture of the first component. The surveillance camera also has a second optical component that extends through the second aperture of the second component. The first optical component is separated from the second optical component by a gap. The first optical component is operatively connected to the device. The first optical component receives the optical signals and transmits the optical signals to the second optical component across the gap to permit a continuous rotation of the first component relative to the second component. The second optical component communicates the optical signals to a destination.
    • 一种监视摄像机,包括用于捕获视频信号并将视频信号转换为光信号的设备。 监视摄像机具有具有第一孔径的第一部件和具有第二孔径的第二部件。 第二部件接合第一部件,使得第一部件相对于第二部件旋转。 监视摄像机具有延伸穿过第一部件的第一孔的第一光学部件。 监视摄像机还具有延伸穿过第二部件的第二孔的第二光学部件。 第一光学部件通过间隙与第二光学部件分离。 第一光学部件可操作地连接到该装置。 第一光学部件接收光学信号,并且将光信号透射穿过间隙到第二光学部件,以允许第一部件相对于第二部件的连续旋转。 第二光学部件将光信号传送到目的地。
