By a News Reporter-Staff News Editor at Health & Medicine Week -- According to news reporting originating from Alexandria, Virginia, by NewsRx journalists, a patent by the inventors Franchini, Luigi (Rimini, IT); Alini, Roberto (Dublin City, CA); Cevini, Filippo (Campbell City, CA), filed on August 11, 2014, was published online on May 15, 2018 (see also Maxim Integrated Products Inc.).
The assignee for this patent, patent number 9971026, is Maxim Integrated Products Inc. (San Jose, CA).
Reporters obtained the following quote from the background information supplied by the inventors: "The background description provided herein is for the purpose of generally presenting the context of the disclosure. Work of the presently named inventors, to the extent it is described in this background section, as well as aspects of the description that may not otherwise qualify as prior art at the time of filing, are neither expressly nor impliedly admitted as prior art against the present disclosure.
"External features of an object can be viewed by a human eye and captured via conventional imaging devices, such as a camera. Internal features of the object, however, generally cannot be readily observed. Ultrasonic imaging devices are used in various fields. For example only, an ultrasonic imaging device may be used for medical imaging, non-destructive testing, non- and minimally-invasive testing, and other fields.
"An ultrasonic imaging device generally includes one or more transmitters and one or more receivers. The transmitters generate test signals that are applied to a probe. The probe includes transducers that move based on the test signals. When the probe is in contact with an object, movement of the transducers causes a wave to propagate through the object. Reflected waves also cause the transducers to move, and the transducers output reflected signals. An image of the internal features of the object can be generated based on the reflected signals."
In addition to obtaining background information on this patent, NewsRx editors also obtained the inventors' summary information for this patent: "In a feature, a transceiver for an ultrasonic imaging device includes a transmit circuit, a receive circuit, a clipper circuit, an amplifier, and a processing module. The transmit circuit outputs test pulses to a probe including a transducer to generate an image of a test object. The composite signal including the test pulses and a reflected signal is output by the transducer. The receive circuit receives the composite signal including the test pulses and the reflected signal and includes a filter circuit that filters the test pulses from the composite signal and passes the reflected signal. An impedance of the filter circuit is equal to substantially zero when the reflected signal is within a predetermined frequency range. The clipper circuit limits a magnitude of an output of the filter circuit. The amplifier amplifies the output of the filter circuit and that outputs an amplified voltage. The processing module generates a signal for displaying the image of the test object based on the amplified voltage.
"In a feature, a transceiver for an ultrasonic imaging device includes a transmit circuit and a filter circuit. The transmit circuit outputs test pulses to a probe including a transducer to generate an image of a test object. A composite signal including the test pulses and a reflected signal is output by the transducer. The filter circuit filters the test pulses from the composite signal and passes the reflected signal and that includes a diode bridge. Diodes of the diode bridge have forward transit times that are greater than one divided by a product of 2.pi. and a minimum value of a predetermined frequency range. An impedance of the filter circuit is equal to substantially zero when the reflected signal is within the predetermined frequency range, and the impedance of the filter circuit is greater than substantially zero when the reflected signal is less than a minimum value of the predetermined frequency range.
"Further areas of applicability of the present disclosure will become apparent from the detailed description provided hereinafter. It should be understood that the detailed description and specific examples are intended for purposes of illustration only and are not intended to limit the scope of the disclosure."
