Abstract: A motion sensor for monitoring the activity of a body in motion includes a pair of force detecting sensors capable of detecting both magnitude and direction of an applied force. These sensors are configured to enable translational or rotational motion resulting from travel in a vehicle to be suppressed from any general motion signal leaving only a rotational or translational component. The active compensation of an electrical circuit is provided to aid in the calibration of a non-ideal sensor pair and reduce the leakage of translational motion into rotational motion or rotational motion into translational motion due to any differences between the pair.

Abstract: Adverse effects due to electrostatic force between a semiconductor substrate and a movable electrode are avoided with a new structure. A movable electrode of beam structure is disposed at a specified interval above a p-type silicon substrate. Fixed electrodes, each composed of an impurity diffusion layer, are disposed on both sides of the movable electrode on the p-type silicon substrate; these fixed electrodes are self-aligningly with respect to the movable electrode. The movable electrode is displaced in accompaniment to the action of acceleration, and acceleration is detected by change (fluctuation) in current between the fixed electrodes generated by means of this displacement. Additionally, an electrode for movable electrode upward-movement use is disposed above the movable electrode, a potential difference is given between the movable electrode and the electrode for movable electrode upward-movement use, and attractive force of the movable electrode to the silicon substrate is alleviated.

Abstract: Disclosed is a roll rate sensor which may form part of a roll position sensor (an "up-sensor") and which comprises a vibratory element rotated by a motor within a projectile body so its rotation speed about the projectile axis is the sum of the motor speed and the projectile roll rate. The resultant centrifugal force acts on the element so as to vary its effective stiffness and hence its vibration frequency. A transducer is arranged to provide a signal corresponding to the vibration and hence to the centrifugal force and the roll rate. The vibratory element may comprise a metallic or silicon beam element.

Abstract: An improved rotational speed governor characterized by a non-linear response to speed changes, includes a control arm, the angular position of which changes in response to the rotational speed of the governor, the control arm carrying a weight held to a fixed position with respect to the control arm at speeds less than a first predetermined speed and displaced from said control arm by centrifugal force at speeds greater than that predetermined speed to effect a non-linear pivotal displacement response to the control arm.

Abstract: A diesel engine mechanical governor is disclosed having various novel features including a fuel modulating and maximum and minimum speed controlling cam plate and follower mechanism which connects the governor speed responsive actuating mechanism with the fuel rack actuating means to modify the effect of the manual fuel control means in a predetermined manner. The disclosure also includes novel rocking flyweight mechanism arranged to provide an output force as a function of rotational input shaft speed in which the exponential increase in centrifugal force upon outward rocking of the flyweights is partially offset to provide a more gradual increase in force with a corresponding increase of speed.
