    摘要: A method of controlling signal power level and a Bluetooth device for performing the same are provided. The method for controlling a power level of a signal to be transmitted to a remote Bluetooth device via a Bluetooth link, comprises: a local Bluetooth device for receiving a first signal from a remote Bluetooth device for determining if the remote Bluetooth device is providing a request to control a power level of the first signal to be transmitted; determining if a power level of a second signal is to be controlled based on a condition of a wireless link when the remote Bluetooth device does not provide the request to control the power level of the first signal; and controlling the power level of the second signal to be transmitted to the remote Bluetooth device.

    摘要: A video cassette recorder operable in a plurality of picture search modes comprises a rotatable knob and a locking mechanism. The knob returns to an initial position thereof when an operational force applied thereto is released. Each of the picture search modes are selected in response to a respective angular displacement of the knob from the initial position. The locking mechanism has a locking arm urged to lock the knob while the video cassette recorder operates in one of the picture search modes.
