    • A method of controlling a data unit sender is described. A flow control procedure for controlling the flow of data units sent by said data unit sender is conducted in dependence on acknowledgement messages from the receiver The flow control procedure utilizes (S103) at least one output limiting parameter (olp; cwnd) for placing a limit on the data units sender's current data send rate. A procedure is provided for detecting (S110) a data unit loss indication, in response to the detection of a data unit loss indication, performing (S311) a retransmission, subsequent to said retransmission (S311) waiting (S312) for an acceptable acknowledgment message carrying the sequence position identifier indicative of said data unit indicated as potentially having been lost, and distinguishing (S317) whether said acceptable acknowledgment message relates to an original transmission, and in response to distinguishing that said acceptable acknowledgment message does not relate to said original transmission, performing (S318) a congestion response step, while in response to distinguishing that said acceptable acknowledgment message relates to said original transmission, said output limiting parameter is adapted (S319) based on one or more duplicate acknowledgment messages received since receiving the last acceptable acknowledgment message that precedes the acceptable acknowledgment message carrying the sequence position identifier indicative of said data unit indicated as potentially having been lost.

    • A radio-frequency (RF) remote control (10) has a user interface and transmits an RF signal (11) which designates a device (14) to be controlled and a command for that device. The RF signal is received by an intermediary device (12). The intermediary device, in turn, generates and broadcasts a plurality of high-power IR signals (13A-13F). These signals may be received directly by a controlled device (14A) or may be received indirectly by a controlled device (14B, 14C) after one or more reflections from objects (16A, 16B) and/or room surfaces (18). Thus, reliable control of the devices (14) is obtained even in situations where merely transmitting a typical IR signal may not provide reliable control of the device (14).
    • 射频(RF)遥控器(10)具有用户接口,并发送指定要控制的设备(14)的RF信号(11)和用于该设备的命令。 RF信号由中间设备(12)接收。 中继装置又产生并广播多个高功率红外信号(13A-13F)。 这些信号可以由受控设备(14A)直接接收,或者可以在来自对象(16A,16B)和/或室内表面(18)的一次或多次反射之后由受控设备(14B,14C)间接接收。 因此,即使在仅发送典型的IR信号的情况下也可以不对设备(14)提供可靠的控制,因此可以获得对设备(14)的可靠控制。
