Abstract: Systems and methods are disclosed and include a needle control module that includes a processor configured to execute instructions stored in a nontransitory computer-readable medium, a motor driver circuit in communication with the needle control module, the motor driver circuit controlling a stepper motor attached to a needle, and a housing enclosing the needle control module, the motor driver circuit, and the stepper motor, the housing being physically attached to a display of a vehicle. In response to the needle control module receiving a signal representing vehicle state information, the needle control module is configured to instruct the motor driver circuit to control movement of the stepper motor and adjust a position of the needle based on the signal.

Abstract: An assembly includes a first structure, a second structure, a hinge that connects the first structure to the second structure for rotation of the first structure relative to the second structure around an axis, and a motion control component. The motion control component applies a feedback force to the hinge in response to an external force that is applied to the first structure. A magnitude of the feedback force is determined based on a current angular position of the first structure relative to the second structure.

Abstract: An indicator of a meter is driven by a step motor in which a rotating magnetic field formed by field coils which is a composite of magnetic fields of the coils supplied with a sine-wave-driving current and cosine-wave driving current. The indicator is also returned to a stopper located at a zero position of the meter by the rotating magnetic field. A part of the rotating magnetic field, which is formed from the sine and cosine waves in a range of the phase angle between -340 degree and -(180 degree-.DELTA.a degree) in the zero-return process, is cut after the indicator rests on the stopper so that such part of the rotating magnetic field may not separate the indicator from the stopper.

Abstract: A pulse motor driving apparatus for the optical unit in a copying machine includes an excitation phase designating circuit for designating phase windings alternately from one phase to two phases and from two phases to one phase at the time of original scanning or forward rotation, and also designating the phase windings in pairs with every two phases at the time of return of the optical unit or reverse rotation. A drive circuit supplies drive pulses successively to the phase windings designated by the excitation phase designating circuit to rotate a pulse motor faster at the time of reverse rotation than at the time of forward rotation.

Abstract: A stepping motor exciting system in which the excitation current is set at one of four stepwise values. When the motor is to be driven in a stepwise manner, the excitation current is in the form of a pseudo-trapezoidal wave which is derived in terms of two of possible four values. When the motor is to be driven in a linear manner, the excitation current is in the form of a pseudo-sinusoidal wave which is derived in terms of all four possible values. A ROM stores these sequences of excitation currents and controls the exciting system in accordance with the driving mode desired.

Abstract: A stepping motor control circuit permitting selective operation of the motor in various modes such as half or full step mode. The circuit includes a pulse generator producing pulses at a selected motor step rate. A switch means selects the step size while a second switch selects the motor direction. An up/down counter counts pulses from the pulse generator in a direction correlated with the selected rotation direction. A read-only-memory is addressed as a function of the periodically repeating count in the up/down counter and the selected step size. The stored information at the addressed read-only-memory location actuates motor drive circuitry which generates energizing signals for the motor windings to drive the motor in the selected direction a distance corresponding to the selected step size at a step rate equal to the pulse rate of the pulse generator.

Abstract: A driving device has a stepping motor for reciprocatively rotationally driving a decorative rotary member. A memory circuit stores a data table on the basis on which the operation timing of the stepping motor is determined. A control circuit controls the application of actuation pulses to the stepping motor on the basis of the data stored in the memory circuit. The data table is made up of numeric values representative of the inter-pulse spacing of the actuation pulses, the inter-pulse spacing being selected such that the rotational speed of the rotary decorative member varies in conformity with a sine curve or the rotation angle of the decorative rotary member varies in conformity with a secant function.
