Title: cooling device for the driving part of a washer
Inventor: HONG SANG UK
IPC: D06F37/30
Filed: 2000-06-10
Abstract: A method of controlling the timing of a transmission time slot within a time frame comprises transmitting information over a channel in an allocated time slot at an allocated channel frequency, measuring a received interference level at the channel frequency around the start and around the end of the time slot, analysing the measured interference levels to detect the presence or absence of interferers at the channel frequency around the start and around the end of the time slot, and, if required, adjusting the timing of subsequent time slots for the channel to reduce interference from the detected interferers. Transmission slot timing of the invention enables dynamic avoidance of interference, which can therefore avoid both intermittent and continuous interferers, and can result in synchronisation of different systems to avoid sliding interferers. This method also enables the throughput of the communication system to be largely unaffected.
