  • Patent number: 11266378
    Abstract: An ultrasound device, including (i) an ultrasound transducer, and (ii) a coupling material in contact with the ultrasound transducer is presented. The coupling material can comprise a solid component and a liquid component, wherein the liquid component is absorbed within the solid component and forms a microscopic liquid layer on a surface of the solid component, through which acoustic energy from the ultrasound transducer can be conducted. The device can be mounted to an external body surface proximate to a portion of the lumen, allowing the device to measure the rate at which a component moves through the lumen. Also provided are methods for making the device and using the device to determine a physiological parameter based on at least the flow rate of a component through the lumen.

  • Patent number: 11259777
    Abstract: According to one embodiment, an ultrasound diagnosis apparatus includes a storage and a control unit. The storage stores transmission/reception conditions for a first ultrasound probe among a plurality of ultrasound probes. Upon receipt of a second switching instruction to switch a second ultrasound probe to the first ultrasound probe after a first switching instruction to switch the first ultrasound probe to the second ultrasound probe, the control unit applies the transmission/reception conditions stored in the storage to the first ultrasound probe when the time between the first switching instruction and the second switching instruction is less than a predetermined time.

  • Patent number: 11246530
    Abstract: A respiratory sensor system provides the ability to determine a respiration rate. The respiratory sensor system may include a respiratory sensor and a software solution, where the software solution determines respiration rate from the respiratory sensor (e.g., microphone) located on the bridge of the user's nose. The respiratory sensor may be placed on or near the nose, such as a microphone located in the nosepiece of a pair of glasses. Due to the placement of the microphone and the respiration detection system design, the wearer respiration rate can be determined reliably even with ambient noise and movement. This makes the respiration rate calculation accessible and reliable, both for everyday wear and for extreme situations such as sports.
