摘要： The present invention provides a method and system for calibration of writing to an optical medium. The method includes: sampling marks in a calibration area of the optical medium; and converting the sampled marks into a digital format utilizing an ADC, the ADC also utilized by a servo control. The present invention provides a controller with an integrated servo and recording processor which allows a single ADC to be used for converting sample marks used in calibrating the writing to an optical media. No separate subsystem for converting sample marks is thus necessary. Less components are required, reducing the cost of manufacturing the controller. With less components, the risk of component failure is reduced as well.

摘要： A method of forming an optical device includes generating a device precursor having a layer of a light-transmitting medium on a base. The method also includes forming an etch stop on the layer of light-transmitting medium. An active medium is grown on the etch stop and on the light-transmitting medium such that the light-transmitting medium is between the base and the grown active medium. The grown active medium is etched down to the etch stop so as to define a ridge in the active medium. The ridge of active medium defines a portion of a component waveguide that will guide a light signal through an active component on the device.

摘要： A device includes an input waveguide on a base. The input waveguide guides a light signal through a light-transmitting medium to a light sensor. The light sensor includes a sensor waveguide on the base. The device also includes a sensor waveguide on the base. The sensor waveguide includes a light-absorbing medium that receives the light signal from the input waveguide. The light-absorbing medium has one or more continuous doped regions that are each positioned such that an application of electrical energy to the doped regions forms an electrical field in the light-absorbing medium. One or more of the doped regions has a first portion that is located within the light-absorbing medium and a second portion located outside of the light-absorbing medium. The device also includes an electrical conductor for applying the electrical energy to one of the doped regions. The electrical conductor contacts the portion of the doped regions that is located outside of the light-absorbing medium.

摘要： Continuous monitoring and fault diagnosis of rotating machinery during variable speed operation is performed using only a position feedback signal. The position sensor generates a periodic waveform having multiple pulses per revolution of the machine. A circuit is included to detect, for example, a zero crossing or edge of the periodic waveform. At each detected zero crossing or edge, the time and position of the event is stored in memory. Other data, such as the current in the motor, may also be sampled and stored in memory. Because the sampled data is triggered by repeated feature of the position feedback signal, the sampled data is in a stationary reference frame in the position domain. Frequency analysis is performed on the sampled data, and the frequency components present in either the sampled signal are analyzed to identify the presence of a fault in the rotating machinery.

摘要： Systems and methods that determine resonant frequencies of a motor system via employing an output of a velocity regulator. The velocity regulator enables the motor drive to command the rotation of the motor at predetermined rotations, by setting rotational speeds of the motor. The output of the velocity regulator can then be stored as a function of time, and a Fast Fourier Transform performed on such time data to obtain a frequency data and a signal power spectrum.
