  • Publication number: 20150109210
    Abstract: A control method, and an input device of a touch screen terminal are provided. A first touch signal that is input, on a touch screen, by a user by using at least one physical key is received, where the at least one physical key is fixed in a specified area on the touch screen; a second touch signal corresponding to the first touch signal is obtained according to a preset correspondence between the first touch signal and the second touch signal, so that control information can be generated according to the second touch signal, and a control operation is performed. Because the physical key is fixed on the touch screen, the physical key protrudes from the touch screen; thereby it is easy for the user to sense the physical key.

  • Publication number: 20130266323
    Abstract: Embodiments of the present disclosure provide a delay measurement method and an optical transport network device. The method includes: acquiring, according to delay information from a first optical transport network device to a second optical transport network device in an optical transport network, a delay of transporting service data from the first optical transport network device to the second optical transport network device; adjusting, according to the delay, residence time of the service data in the optical transport network so that the time is equal to a preset reference delay. Through the method of the present disclosure, uplink and downlink delays can be accurately measured, and the residence time of the service data in the optical transport network is adjusted to be consistent with the reference delay, thereby solving the problem in the prior art of inaccurate delay measurement resulting from asymmetry between uplink and downlink delays.
