| 20140327900 | DISTANCE SENSING BY IQ DOMAIN DIFFERENTIATION OF TIME OF FLIGHT (TOF) MEASUREMENTS - A system and method for identifying a position of a moving object, regardless of static objects present in the optical field of an active infrared (IR) proximity detector, is provided. Moreover, a modulated light emitting diode (LED) signal is captured and processed through I/Q demodulation. Specifically, the reflections received at an IR sensor are demodulated to generate in-phase (I) and quadrature phase (Q) signals and the derivative of I/Q signals is obtained to isolate motion. For example, an I/Q domain differentiator or a high pass filter is employed to calculate the derivative, which actively remove the effects of all forms of static interference. Further, the phase of the derivative I/Q signals is determined and is utilized to reconstruct the distance at which the motion occurred. | 11-06-2014 |
| 20150009484 | Chromatic Range Sensor Probe Detachment Sensor - A system and method for a chromatic probe detachment sensor is provided. A detachment signal element is included in an interchangeable optics element of a probe. The detachment signal element is configured to substantially transmit a first set of wavelengths corresponding to a measuring range, and at least partially reflect a set of detachment element wavelengths. In one implementation, the detachment signal element comprises a thin film coating such as a sharp edge filter. The detection of a detachment condition can thus be achieved using the existing probe electronics without requiring the addition of other external sensors or wiring to the probe or coordinate measuring machine that utilizes the probe. The sensing of a detachment condition may be utilized to halt further movement of the probe to minimize damage in the event of a collision. | 01-08-2015 |
| 20150109602 | PHOTOLUMINESCENT ILLUMINATORS FOR PASSIVE ILLUMINATION OF SIGHTS AND OTHER DEVICES - A photoluminescent capsule illuminator for a sighting device.
