Abstract

A timing apparatus, system, and method are provided to determine a position of a rotating object in a device, such as an engine, and control the device according to the determined position of the rotating object. Light is emitted from a light source onto a reflecting region on a portion of the rotating object. Light is reflected off the reflecting region of the rotating object and detected as the rotating object rotates. Intensity of the reflected light is measured, via a microcontroller, and the position of the rotating object is determined according to the intensity of the detected light. A signal is generated that corresponds to the intensity of the detected light associated with the determined position of the rotating shaft. The reflecting region has a feature configured to effect a change in the intensity of the reflected light as the rotating object rotates. The microcontroller is configured to determine the determined position and to utilize the determined position and the change in the signal to control operating characteristics of the device.

Abstract

A programmable cylinder, a system and a method change a velocity of a machine element within a compartment. A light detector within the compartment determines that the machine element is located at a first position or at a second position and/or is moving at a first velocity or at a second velocity. Switches determine that the machine element may be located at the first position or at the second position and/or is moving at the first velocity or at the second velocity. A microprocessor transmits a control signal to a transducer to alter an electrical current of the transducer to move valves of the compartment between an open position and a closed position. A compressed fluid within the interior of the compartment is changed via the valves. The machine element is accelerated and/or is decelerated to the first velocity or to the second velocity via the compressed fluid. A graphic user interface and/or a terminal accesses and controls the microprocessor and/or the transducer to move the machine element at the first velocity or at the second velocity within the compartment.

Abstract

A light pipe, a system and a method measure light attenuation from an optical fiber connected to a light source. The optical fiber transmits light from the light source to a light detector to determine a distance between the optical fiber and the light detector. The optical fiber attenuates light outwardly with respect to the fiber. A layer receives the optical fiber to reflect and/or to refract light transmitted by the optical fiber inwardly. A rod prevents light from attenuating from the optical fiber. A microprocessor may be connected to the light detector for determining the amount of light attenuated from the optical fiber. The microprocessor determines the distance between the light detector and the optical fiber based on the amount of light transmitted from the optical fiber to the light detector. The microprocessor transmits an output signal to a transducer for activating an arm to move an end of the layer inwardly or outwardly with respect to an end of the optical fiber. The light attenuated from the optical fiber and/or the light detectable by the light detector may correspond to a distance between the optical fiber and the light detector within an interior of the layer. The microprocessor may identify the distance between the optical fiber and the light detector based on the light measured and/or detected by the light detector from the optical fiber which may not be attenuated from the optical fiber.

Abstract

A collar, a system and a method detect a mark on a rod within an interior of the collar. The mark and the rod move from a first position to a second position within an interior of the collar between a first end and a second end of the collar. A light emitter and/or a light detector is connected to the collar for determining the first position and/or the second position of the mark and/or of the rod within the interior of the collar. An exterior surface of the rod and/or a mark on the rod absorb an amount of light emitted from the light emitter within the interior of the collar. The light detector measures and/or detects an intensity of light within the interior of the collar which is not be absorbed by the mark and/or by the exterior surface of the rod. The intensity of light within the interior of the collar detected by the light detector that is not absorbed by the mark or the exterior surface of the rod corresponds to the first position and/or to the second position of the mark within the interior of the collar.

Abstract

A system and a method detect that a movable element within an interior of a compartment is at an end of a stroke and/or a beginning of the stroke within the interior of the compartment. A switch and/or an electrical circuit is connected to the compartment for detecting that the movable element may be at the beginning of and/or at the end of the stroke. A microprocessor is connected to the switch or to the electrical circuit for detecting that the movable element is at the end of and/or at the beginning of the stroke within the interior of the compartment. An end cap having a light detector is connected to the compartment to measure an intensity of the light within an interior of the end cap which is attenuated by and/or is diffused by a surface of the movable element and/or of the compartment. The intensity of the light within the interior of the end cap corresponds to a position of the movable element within the interior of the compartment. The light detector determines the position of the movable element which is at the end of the stroke, at the beginning of the stroke and/or between the end of the stroke and the beginning of the stroke via the intensity of light within the interior of the end cap.

Abstract

A system and a method detect a position of a movable element within the interior of the compartment via a light source and/or a light sensor. The light sensor is connected to a platform and/or to a film for detecting an intensity of a light within the interior of the compartment. The film, a bottom surface of an end cap and/or a surface of the movable element and/or the compartment attenuate light within the interior of the compartment and/or within an interior of the end cap. The intensity of the light detectable by the light sensor corresponds to the position of the movable element within the interior of the compartment. The position of the movable element within the interior of the compartment is detected by the light sensor via the intensity of the light detectable by the light sensor. The film, the platform, the bottom surface of the end cap and/or the surface of the movable element and/or of the compartment minimize diffraction of the light within the interior of the compartment and/or within the interior of the end cap.
