摘要： Disclosed are various embodiments for implementing automatic firmware rollbacks after a configured number of attempts to execute the latest firmware update associated with an electronic computing unit have occurred. In a computing device, such as an electronic computing unit, a watchdog automatically generates a system reset in response to a software fault. A reset counter is configured to count a number of system resets generated by the watchdog. In response to the occurrence of the watchdog, a configurable threshold value associated with a threshold data record is compared with the value associated with the reset counter. In response to a determination that the threshold value associated with the threshold data record is greater than or equal to the value associated with the reset counter, a rollback application is executed such that the rollback application performs a swap of a first version of a firmware with a second version of the firmware.

摘要： A MEMS device includes a two spring systems coupling a pair of movable masses. Each of the spring systems includes a constrained stiff beam and a pair of flexures, where one flexure is directly coupled to one end of the stiff beam and to one of the movable masses and the other flexure is directly coupled to the opposing end of the stiff beam and to the other movable mass. In response to drive movement of the movable masses, the flexures enable pivotal movement the constrained stiff beams such that the stiff beams pivot in opposing directions about their center hinge points. This pivotal movement enables anti-phase linear oscillatory motion of the drive masses while substantially suppressing or otherwise rejecting in-phase motion of the movable masses.
