Patent number: 10502718Abstract: A method and system is disclosed for determining an optimum drive signal for an acoustic transducer. A pulse signal is employed as a wideband reference signal Vr(t); and, in a pulse-echo measurement a corresponding wideband echo signal Ve(t) is obtained. A normalized loop frequency response {circumflex over (X)}(f) for the acoustic transducer is defined as a ratio of a Fourier Transform of the Ve(t) to a Fourier Transform of the Vr(t), and a normalized loop time response X(t) is defined as an Inverse Fourier Transform of the {circumflex over (X)}(f). An optimum drive signal B(t) for the acoustic transducer is defined as B(t)?*G(t), wherein a coefficient ? is determined to multiply a function G(t), in which the function G(t) is derived from one of the normalized loop time response X(t) and the normalized loop frequency response {circumflex over (X)}(f).Type: GrantFiled: December 27, 2017Date of Patent: December 10, 2019Assignee: BROADSOUND CORPORATIONInventors: Ying-Wei Yuan, Jen-Chih Yao, Fu-Chieh Yang, Yi-Hsun Lin

Patent number: 10495454Abstract: An inspection system, in an embodiment, can be operable with a probe and a position tracker to inspect an object. The system can be operable to display at least one probe travel axis, receive first and second inspection values from the probe, associate the first inspection value with a first position point, and associate the second inspection value with a second position point. The system displays an inspection path based on the associations. The inspection path extends relative to the probe travel axis.Type: GrantFiled: June 7, 2018Date of Patent: December 3, 2019Assignee: General Electric CompanyInventor: Daniel Scott Groninger

Patent number: 10187504Abstract: A device and a corresponding method are provided to tune parameters of an echo control process without re-initializing the echo control process and without interrupting a playback process. A state of the device and environment around the device is computed during use of the device given information from sensors. Such sensors can give information on the position of the device, the orientation of the device, the presence of a proximate object, or handling of the device resulting in occlusion of microphones and loudspeakers, among other things. The computed state of the device is mapped to an associated device state code from among a plurality of device state codes. The parameters of the echo control process are tuned either according to the associated device state code, or a change in such a code, during use of the device.Type: GrantFiled: September 23, 2016Date of Patent: January 22, 2019Assignee: Apple Inc.Inventors: Sean A.

Patent number: 10183166Abstract: Methods, medical devices, and magnetic resonance imaging (MRI) systems are provided. A patient implanted with a medical device is exposed to a time-varying magnetic field having a signature, thereby inducing mechanical vibrations in at least one component of the medical device. A vibrational characteristic of the mechanical vibrations induced in the component(s) is detected. The vibrational characteristic is analyzed, and the signature of the magnetic field is identified based on the analyzed vibrational characteristic. The medical device is automatically switched from a first operational mode to a second operational mode when the signature is identified.Type: GrantFiled: June 20, 2014Date of Patent: January 22, 2019Assignee: BOSTON SCIENTIFIC NEUROMODULATION CORPORATIONInventors: Kiran K.
