  • Power control method and apparatus for tracking maximum power point in a photovoltaic system
    Patent number: 8810213
    Abstract: A power control method for tracking a Maximum Power Point (MPP) in a photovoltaic system including a solar cell and a boost converter. The power control method includes finding the MPP by applying a continuous ON/OFF signal to the boost converter as a first control signal for controlling a duty ratio of the boost converter, and maintaining an operating point of the photovoltaic system at the MPP by applying a second control signal for controlling the duty ratio to the boost converter depending on a constant-voltage command. In tracking an MPP in a photovoltaic system, an MPPT algorithm may remain at the MPP, without self oscillation, improving fast dynamic characteristics upon a change in solar radiation.

  • Method and system for interrupted floor recovery in push-to-talk over cellular network
    Patent number: 8812042
    Abstract: As described above, when a particular PoC client participating in a PoC session requests media transmission to a PoC server during transmission of media from another PoC client, the PoC server transitions the PoC client with the floor to a suspended state by sending an MB Suspend message and grants the floor to the requesting PoC client. After media transmission of the interrupting PoC client, the PoC server returns the floor to the interrupted PoC client. Therefore, the privileged PoC client in a current PoC infrastructure interrupts the ongoing conversation and sends media, after which the floor is returned to the interrupted PoC client without issuing an explicit media request from the interrupted PoC client. Even in the pre-emptive case scenario where the pre-emptive PoC client interrupts the ongoing conversation, the conversation can be continued in a natural way.
