Patent number: 11815492Abstract: Aspects of the technology described herein relate to built-in self-testing (BIST) of circuitry (e.g., a pulser or receive circuitry) and/or transducers in an ultrasound device. A BIST circuit may include a transconductance amplifier coupled between a pulser and receive circuitry, a capacitor network coupled between a pulser and receive circuitry, and/or a current source couplable to the input terminal of receive circuitry to which a transducer is also couplable. The collapse voltages of transducers may be characterized using BIST circuitry, and a bias voltage may be applied to the membranes of the transducers based at least in part on their collapse voltages. The capacitances of transducers may also be measured using BIST circuitry and a notification may be generated based on the sets of measurements.Type: GrantFiled: April 15, 2021Date of Patent: November 14, 2023Assignee: BFLY Operations, Inc.Inventors: Chao Chen, Youn-Jae Kook, Jihee Lee, Kailiang Chen, Leung Kin Chiu, Joseph Lutsky, Nevada J.

Patent number: 11690595Abstract: Aspects of the technology described herein relate to wirelessly offloading, from a wearable ultrasound device, ultrasound data sufficient for forming one or more ultrasound images therefrom. The wearable ultrasound device may include an ultrasound patch. Indications that may be monitored with such a device, and therapeutic uses that may be provided by such a device, are also described. Methods and apparatuses are also described for compounding multilines of ultrasound data on an ultrasound device configured to collect the ultrasound data. Additionally, certain aspects of the technology relate to non-uniform grouping of ultrasound transducers that share a transmit/receive circuit in an ultrasound device.Type: GrantFiled: April 9, 2019Date of Patent: July 4, 2023Assignee: BFLY Operations, IncInventors: Nevada J.

Publication number: 20220313207Abstract: Ultrasound devices are described. The ultrasound devices may be flexibly configured to output a certain number of multilines per channel of ultrasound data and to process certain channels of ultrasound data per processing cycle. The ultrasound device may then be configured to either output more multilines per channel and process fewer channels per processing cycle, or output fewer multilines per channel and process more channels per processing cycle. In other words, the circuitry may be configured to change to a configuration with increased resolution and increased processing time or to a configuration with decreased resolution and decreased processing time.Type: ApplicationFiled: March 31, 2022Publication date: October 6, 2022Applicant: BFLY Operations, Inc.Inventors: Hamid Soleimani, Nevada J.

Publication number: 20210330295Abstract: Beamforming circuitry for an ultrasound device is disclosed, that may directly calculate the position in receive line space for an incoming ultrasound data sample given the time of flight (ToF) of that ultrasound data sample. In some embodiments, this may be done without initially buffering the ultrasound data sample received from the particular receive datapath multiplexed to the beamforming circuitry. The beamforming circuitry may then associate the ultrasound data sample with that position in receive line space, and in particular, with a memory address corresponding to that location. Thus, when the beamforming circuitry multiplexes between different receive datapaths, it may not need to buffer ultrasound data samples from different receive datapaths prior to saving the data to memory.Type: ApplicationFiled: April 21, 2021Publication date: October 28, 2021Applicant: Butterfly Network, Inc.Inventors: Hamid Soleimani, Karl Thiele, Sheng-Wen Huang, Nevada J.

Publication number: 20180233530Abstract: An image sensor including a semiconductor layer. A light absorber layer couples with the semiconductor layer at a pixel of the image sensor and absorbs incident light to substantially prevent the incident light from entering the semiconductor layer. The light absorber layer heats a depletion region of the semiconductor layer in response to absorbing the incident light, creating electron/hole pairs. The light absorber layer may include one or more narrow bandgap materials.Type: ApplicationFiled: April 12, 2018Publication date: August 16, 2018Applicant: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Victor LENCHENKOV, Hamid SOLEIMANI

Patent number: 9812555Abstract: An integrated circuit die may include bottom-gate thin-body transistors. The bottom-gate thin-body transistors may be formed in a thinned-down substrate having a thickness that is defined by shallow trench isolation structures that provide complete well isolation for the transistors. The transistors may include gate terminal contacts formed through the shallow trench isolation structures, bulk terminal contacts that are formed through the thinned substrate and that overlap with the gate contacts, and source-drain terminal contacts with in-situ salicide. Additional metallization layers may be formed over the gate/bulk/source-drain contacts after bonding.Type: GrantFiled: May 28, 2015Date of Patent: November 7, 2017Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Raminda Madurawe, Hamid Soleimani, Irfan Rahim

Patent number: 9584744Abstract: An image sensor with an array of image sensor pixels is provided. Each pixel may include a photodiode, a storage diode, and associated circuitry formed in a semiconductor substrate. Buried light shields may be formed on the substrate to prevent regions between two adjacent photodiodes from being exposed to incoming light. In one embodiment, a shallow trench isolation (STI) structure may be formed between the photodiode and the storage diode, and a conductive layer formed from optically absorptive material may be constructed at the bottom of the STI structure. A via may be formed through the STI structure to help bias the conductive layer using a ground or negative voltage. In another embodiment, an isolation ring structure may be formed at the base of the buried light shields. The isolation ring structure may be formed from optically absorptive material and can optionally be biased using a ground or negative voltage.Type: GrantFiled: June 23, 2015Date of Patent: February 28, 2017Assignee: SEMICONDUCTOR COMPONENTS INDUSTRIES, LLCInventors: Victor Lenchenkov, Hamid Soleimani
