    摘要: A safety seat (100) includes a seat body (10) and a set of caster wheels (11). The safety seat can ride on the caster wheels (11). The safety seat can also include a handle (12) for easy manipulation and a footrest (13) for the child to rest the feet. The caster wheels (11), the handle (12) and the footrest (13) can be retracted when they are not used and extended out when needed.

    摘要: An improved double balanced mixer is provided which in one embodiment includes a first balun for receiving a first single input and providing a first balanced output having two ports, a second balun for receiving a second single input and providing a second balanced output having two ports, and a balanced mixer core responsive to the first and second balanced outputs to provide a mixed signal from the first and second single inputs. The first balun includes an RC network coupled between at least one of the ports of the first balanced output and one of ground and a common mode node of the first balun to improve the linearity of the double balanced mixer.
