Patent number: 10630298Abstract: Systems and processes disclosed herein determine the temperature of a crystal, such as a crystal that may be used in a crystal oscillator, using the reference crystal itself. The system can measure the temperature of the crystal without a temperature sensor. Further, a single oven technique may be used to maintain the temperature of the reference crystal. Thus, in certain embodiments, a more compact crystal oscillator can be generated compared to conventional techniques. Further, by measuring the reference crystal based on signals generated by the reference crystal itself, the system disclosed herein is more accurate than many previous crystal oscillator systems.Type: GrantFiled: August 10, 2018Date of Patent: April 21, 2020Assignee: Greenray Industries, Inc.Inventor: Steven J. Fry

Patent number: 10069498Abstract: A packaged VCTCXO may include a crystal oscillator configured to output a signal of a particular frequency and a temperature sensor configured to measure an internal temperature of the crystal oscillator. In addition, the packaged VCTCXO may include a microcontroller configured to generate an internal control voltage signal based at least in part on the temperature and an external control voltage received by the packaged VCTCXO. Moreover, the packaged VCTCXO may include a combiner configured to combine an internal control voltage and the external control voltage to generate a control voltage. Further, the control voltage may be supplied to the crystal oscillator to cause the crystal oscillator to generate the signal of the particular frequency.Type: GrantFiled: May 30, 2017Date of Patent: September 4, 2018Assignee: Greenray Industries, Inc.Inventor: Jonathan George Scott

Patent number: 9385653Abstract: A crystal oscillator having a plurality of quartz crystals that are manufactured so that the directional orientation of the acceleration sensitivity vector is essentially the same for each crystal. This enables convenient mounting of the crystals to a circuit assembly with consistent alignment of the acceleration vectors. The crystals are aligned with the acceleration vectors in an essentially anti-parallel relationship and can be coupled to the oscillator circuit in either a series or parallel arrangement. Mounting the crystals in this manner substantially cancels the acceleration sensitivity of the composite resonator and oscillator, rendering it less sensitive to vibrational forces and shock events.Type: GrantFiled: May 27, 2015Date of Patent: July 5, 2016Assignee: Greenray Industries, Inc.Inventors: Steven Fry, Wayne Bolton, John Esterline

Patent number: 9092729Abstract: Systems and methods for controlling frequency output of an electronic oscillator to compensate for effects of one or more parameters experienced by the oscillator incorporate artificial neural network processing functionality for generating correction signals. A neural network processing module includes one or more neurons which receive one or more inputs corresponding to parameters of an electronic oscillator, such as temperature and control voltage (or correction voltage). One or more sets of weights are calculated and applied to inputs to the neurons of the neural network as part of a training process, wherein the weights help shape the output of the neural network processing module. The neural network may include a linear summation module configured to provide an output signal that is at least partially based on outputs of the one or more neurons.Type: GrantFiled: July 21, 2014Date of Patent: July 28, 2015Assignee: Greenray Industries, Inc.Inventor: John C.

Patent number: 9092730Abstract: Systems and methods of using an artificial neural network processing module to compensate a control voltage and create a linear output response for an electronic oscillator to produce a target frequency. The artificial neural network processing module includes one or more neurons which receive one or more inputs corresponding to the control voltage. The artificial neural network processing module is configured to provide a correction based at least in part on the control voltage and pre-calculated DAC values. The pre-calculated DAC values are determined in part by predetermined or predefined pull ranges and linear control voltage transfer functions. The artificial neural network processing module can preferably achieve a control voltage tuning linearity better than 0.5% linearity over an entire tuning range of +?75 ppm.Type: GrantFiled: December 11, 2014Date of Patent: July 28, 2015Assignee: Greenray Industries, Inc.Inventors: John C.
