摘要： A high-frequency hybrid switch module arranged applicable to at least two different communications systems includes two low pass filters (LPFs), two phase shifters, a field effect transistor (FET) switch including FETs, and two SAW filters. The FETs and the SAW filters are mounted on a layered assembly including the LPFs and an electrode pattern of the phase shifters. The module can have a small overall size, a low cost, and a small loss, while being protected from static electricity. The module requires small number of low-noise amplifiers at a signal receiving side.

摘要： A data collection method of the present invention uses measuring terminals, each of measuring terminals can obtain measurement data from a sensor and wirelessly transmit the measurement data, and a collection terminal for receiving the measurement data from the measuring terminals, each measuring terminal having a memory that stores, as its own identification information, one of a limited number of sets of identification information whose order can be defined. The data collection method comprises: an inquiring step in which the collection terminal wirelessly transmits a message for inquiring about identification information; a first responding step in which each measuring terminal, on receiving the message, wirelessly transmits its own identification information when, after the message has ended, a turn for sending its own identification information is reached; a first identifying step in which the collection terminal stores the sets of identification information received in reply in the order of the sets of identification information; and a collecting step in which the collection terminal wirelessly communicates individually with the measuring terminals that have the stored sets of identification information and collects the measurement data from the measuring terminals. By the collection method, data can be automatically collected from the measuring terminals.
