Abstract: A transmission part transmits a packet by radio. A power detection part performs, at a given cycle, sampling of power of a spatial radio signal in a packet transmission period during which the transmission part transmits the packet. A collision detection part calculates, as an index value, at least one of the average value and the degree of variation of power of the spatial radio signal in the packet transmission period on the basis of sampled data obtained in the sampling by the power detection part. The collision detection part also determines a reference value on the basis of transmission power of the packet. The collision detection part detects whether or not collision of the packet is present by comparing the index value with the reference value.

Abstract: A MEMS device includes a drive spring system coupling a pair of drive masses and a sense spring system coupling a pair of sense masses. The drive spring system includes a constrained stiff beam and flexures interconnecting the pair of drive masses. In response to drive movement of the drive masses the flexures enable pivotal movement of the constrained stiff beam about its center hinge point to enable anti-phase drive motion of the drive masses and to suppress in-phase motion of the drive masses. The sense spring system includes diagonally oriented stiff beams and a spring system that enable anti-phase sense motion of the sense masses while suppressing in-phase motion of the sense masses. Coupling masses interposed between the drive and sense masses decouple the drive motion of the drive masses from the sense motion of the sense masses.
