  • Patent number: 12156589
    Abstract: A multifunctional table includes a table body, a carrier member, and a holder. The table body includes a board and a support member connected to each other. The board has a table top and a groove. The carrier member is connected to the table body and includes a first slideway. The holder includes a slidable attaching portion and a holding portion connected to each other. The holding portion includes a first holding surface. The first holding surface corresponds to the groove when the slidable attaching portion is slidably attached to the first slideway in a first attached state. A holder includes a slidable attaching portion and a holding portion connected to each other. The holding portion includes a first holding surface and a second holding surface opposite to each other. The first holding surface and the second holding surface are asymmetrical about a central x axis of the holder.

  • Patent number: 11128333
    Abstract: A signal receiving circuit amplifies a radio frequency signal by using a first radio frequency amplifier, outputs a first amplified signal in a same phase, amplifies the radio frequency signal by using a second radio frequency amplifier, and outputs a second amplified signal at an inverse phase. A first mixer mixes a first local oscillator signal with the first amplified signal to obtain a first frequency mixing signal, and a second mixer mixes a second local oscillator signal with the second amplified signal to obtain a second frequency mixing signal, where a phase of the first local oscillator signal is opposite to a phase of the second local oscillator signal. After adding the first frequency mixing signal and the second frequency mixing signal, an output interface outputs the first frequency mixing signal and the second frequency mixing signal.

  • Publication number: 20210273773
    Abstract: A transceiver system is configured to concurrently send TX signals and receive RX signals on an antenna system in the same frequency band. A bi-directional frequency converter circuit modulates the TX signals and RX signals by a modulation frequency. The modulated TX signals and RX are frequency shifted so that they have different frequencies that are not in the same frequency band. For example, the TX signal may be shifted to a higher frequency and the RX signal may be shifted to a lower frequency. Filters can then be used to isolate the TX signal and the RX signal for transmission and/or processing.
