Patent number: 11474078Abstract: The embodiments disclosed herein relate to the examination of gemstones including diamonds, both cut/polished and rough, using the technology of Resonant Ultrasound Spectroscopy. The resonant frequencies are obtained by mechanically causing the stone to vibrate using a swept sine oscillator, sensing the resonance vibrations, and displaying the spectrum to yield a pattern describing the stone. The resonance fingerprints can be used to both track an individual stone to verify its integrity or to grade a rough stone to establish potential value.Type: GrantFiled: February 27, 2018Date of Patent: October 18, 2022Assignee: Gemological Institute of America, Inc.

Patent number: 11467131Abstract: Embodiments of the disclosure provide systems and methods for detecting a resonant frequency of an optical beam-steering device. The method may include driving the optical beam-steering device with a driving signal oscillating at a plurality of frequencies. The method may also include detecting, by an acoustic detector, an acoustic signal caused by a movement of the optical beam-steering device. The method may further include analyzing a spectrum, by a controller, of the acoustic signal. The method may additionally include determining, by the controller, the resonant frequency of the optical beam-steering device based on the spectrum.Type: GrantFiled: June 19, 2020Date of Patent: October 11, 2022Assignee: BEIJING VOYAGER TECHNOLOGY CO., LTD.Inventors: Sergio Almeida, Youmin Wang

Patent number: 11467075Abstract: A method is provided for increasing accuracy in measuring complex Young's modulus and complex shear modulus of a material using a processing system. The material is tested to obtain an experimental frequency response transfer function of normal displacement to input force. A model panel is developed in the processing system as a modeled frequency response transfer function. The modeled transfer function is used at a range of fixed frequencies to calculate displacements of the model panel divided by the input force while varying material parameters. The modeled frequency response transfer function is compared with the experimental frequency response transfer function to compute error function values. These values indicate the most accurate material property values as those minimizing the computed error function values.Type: GrantFiled: September 21, 2018Date of Patent: October 11, 2022Inventor: Andrew J Hull

Patent number: 11457836Abstract: Active auscultation may be used to determine organ (e.g., lung or heart) characteristics of users. An acoustic or piezo-electric signal (e.g., a pulse, a tone, and/or a broadband pulse) may be projected into an animal (typically human) body or thorax. The signal interacts with the body, or lungs, and in some cases may induce resonance within the body/lungs. A resultant signal may be emitted from the body which may be analyzed to determine, for example, a lung's resonant frequency or frequencies and/or how the sound is otherwise absorbed, reflected, or modified by the body. This information may be indicative of lung characteristics such as lung capacity, a volume of air trapped in the lungs, and/or the presence of COPD.Type: GrantFiled: July 22, 2021Date of Patent: October 4, 2022Assignee: RESPIRA LABS, INC.Inventor: Maria Artunduaga

Patent number: 11462058Abstract: A system may include a device. The device may be configured to receive machine vibration data identifying a measure of vibration of a machine. The vibration, of the machine, may be caused by a combination of first vibration caused by a motion of components of an undercarriage of the machine and second vibration that is unrelated to the first vibration. The device may be configured to identify a segment, of the machine vibration data, corresponding to the first vibration; transform the segment, using a Fast Fourier Transform (FFT), into a signal in a frequency domain; and analyze the signal to identify a signature spectrum associated with the motion of components. The device may be configured to predict, based on the signature spectrum, an amount of wear of the components. The device may be configured to cause an action to be performed based on the amount of wear of the components.Type: GrantFiled: October 29, 2020Date of Patent: October 4, 2022Assignee: Caterpillar Inc.Inventors: Li Zhang, Yingbiao Xu

Patent number: 11456647Abstract: A rotating electrical machine of the present invention evaluates a relative displacement of members and improves reliability further even when two or more members operate or move. A rotating electrical machine of the present invention comprises a stator and a rotor disposed on an inner side of the stator with a predetermined gap. The stator includes vibration measuring devices, each of the vibration measuring devices placed on each of at least two members included in the stator, the members having different displacements or phases with each other. The rotating electrical machine includes a device that acquires a relative displacement of one of the members included in the stator by evaluating a difference between displacements or phases measured by the vibration measuring devices and that evaluates a lifetime of the one of the members included in the stator based on the relative displacement.Type: GrantFiled: October 25, 2018Date of Patent: September 27, 2022Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Yuichi Sekine, Keiji Suzuki, Keisuke Kumano, Tamami Kurihara, Yuichi Takahashi
