Abstract: An inflatable model with lighting effects includes a light-transmissive inflatable body, an air supply component for inflating the interior of the light-transmissive inflatable body, and a main light source which emits light from the interior of the light-transmissive inflatable body. The light-transmissive inflatable body is divided into a plurality of decoration areas. Each decoration area is provided with at least one effect light source. According to the present invention, various lighting effect combinations on the inflatable model can be achieved, thus enriching the exhibition effect of the inflatable model. Therefore, the inflatable model in the present invention can attract attention of people more easily and is more suitable for activity meeting places with diversified lighting effect requirements such as Halloween, Christmas, and the like.

Abstract: This application provides a communications system (100) for automatically selecting an NFC emulation card, which includes an NFC card reader (102) and an electronic device (101). The NFC card reader (102) sends third query information which includes first identification information and a service type of an emulation card. The electronic device (101) determines whether a first emulation card exists. When determining that the first emulation card exists, the electronic device (101) determines whether a second emulation card exists. When determining that the second emulation card exists, the electronic device (101) sends fourth response information which carries second identification information. The NFC card reader (102) sends card selection instruction information. The electronic device (101) receives the card selection instruction information, and sends card selection response information.

Abstract: Disclosed is a method for configuring an MSD parallel adder based on ternary logic operators. Five ternary logic operators that satisfy a sufficient condition for MSD addition are used to configure an MSD parallel adder. During the arrangement of a ternary logic operator, any method in the following may be used: each of ternary operators of n bits is reconfigured into a ternary logic operator each time, and reconfiguration is performed five times for implementation; each of ternary operators of n bits is reconfigured into two ternary logic operators having the same input each time, and reconfiguration is performed three times for implementation; each of ternary operators of n bits is reconfigured into five ternary logic operators of the same time, and reconfiguration is performed once for implementation; corresponding unreconfigurable ternary logic operators are used instead for the foregoing reconfiguration process.
