Latest Patents

Funayama’s listed patent, “Channel Switching System,” describes a method for monitoring standby channels in a digital radio communication system. The system uses regular channels for communication and standby channels that transmit test signals. A control signal designates standby channels in turn when multiple channels are available, or selects the sole standby channel when only one is available. Synchronizing switching means then outputs the test signal from the designated channel, while monitoring means evaluates the signal to assess the standby channel’s communication quality. This approach supports synchronized switching from a regular channel to a suitable standby channel.
