    摘要： A surface micromachined microaccelerometer includes a substrate which has a surface plane, and a cantilever formed on the substrate with a fixed end and a free end, the fixed end being anchored to the substrate. The cantilever includes a mass fixed along the length of the cantilever. A cooperating device reads out the occurrence of an acceleration event when the free end of the cantilever has moved to a predetermined position. The cooperating device may be fixed or an opposing co-aligned cantilever structure. In a first embodiment, the cooperating device takes the form of a fixed structure having slots in which the tip of the cantilever is selectively retained. A further embodiment configures the cooperating device as an overlapping opposed cantilever. A further feature of the invention enables a reset function of a latched cantilever and comprises a pair of layers which when energized cause a cantilever to be suitably deflected so as to return from the latched state back to the unlatched state.

    摘要： A CPU measures pulse width of a vehicle speed pulse signal transmitted from a vehicle speed sensor continuously and estimates the pulse width coming next according to the pulse width of the present pulse and preceding pulses. The CPU calculates a set position of a stepping motor from the data of the pulse width and the estimated pulse width, and calculates the number of steps for the stepping motor to move to the set position from the set position data and the present position data. Each driving time of the stepping motor is calculated from the estimated pulse width data and the number of steps.

    摘要： A device for affording an indication when a predetermined mechanical shock has been received, characterized by a base, or means for attaching to a container to be monitored; structure for measuring when a predetermined acceleration has been received by the container and the device; and an indicator for indicating to an observer that the shock has been received. Disclosed are devices having (1) a mechanical structure with a breaking point; (2) a mechanical structure with a biasing means; and (3) a structure employing an interfacial tension phenomenon. The devices may be of the "go-no go" type or may afford an indication and history of the shock, or acceleration forces, received. Also disclosed are the specific details of the respective embodiments.
