  • Patent number: 8521792
    Abstract: The present invention discloses a rate multiplication method for counting a sequence of original pulse signals and outputting a target pulse signal. In this method a comparison data and original pulse signal sequence is received. The original pulse signal sequence is counted in order to obtain a pulse count. Comparing the pulse count and the comparison data. If the pulse count is equal to the comparison data, a corresponding original pulse signal is outputted as the target pulse signal. Reset and recount the pulse count, and obtain which repeatedly. In this present invention the pulse count and the pulse interval between the target pulse signals can be determined freely according to a rate.

  • Publication number: 20040183785
    Abstract: An input apparatus for an electronic system with a plurality of hosts. Each of the input apparatuses and the hosts has a radio module. Each radio module has a unique identity and is capable of transmitting and receiving radio packet signals. When the radio module of a host receives a packet including the identity of the host, the host will resolve information in the packet. If the host receives a packet including an identity of another host, the host will discard and ignore the packet. The input apparatus also has an input interface, and stores the identities of the hosts. A user can select a host identity with the input interface, and the radio module of the input apparatus will transmit packets including the selected identity and commands inputted with the input interface, such that the host corresponding to the selected identity will receive commands inputted by the user without interfering with other hosts.
