Samsung Medison Co., Ltd. (Korean: 삼성메디슨) is a manufacturer of diagnostic ultrasound systems. The company was founded in 1985 and acquired by Samsung in 2010 [ 1 ] with the purchase reported to be at more than $262 million US dollars. [ 2 ]
The Samsung Galaxy Buds 2 (SM-R177) were announced on August 11, 2021, at Galaxy Unpacked alongside the Galaxy Watch 4. [19] The Buds 2 were seen as the successor to the Buds Plus, which were discontinued following the announcement. [ 20 ]
The Galaxy Buds Live feature active noise cancellation, a bean shape and a wingtip design. Black, white, and Mystic Bronze are the available colour variations for the earbuds. The earbuds measure 2.8 cm longitudinally and 1.3 cm wide whilst the charging case is 2.6 cm thick.
Portable ultrasound is a modality of medical ultrasonography that utilizes small and light devices, compared to the console-style ultrasound machines that preceded them. In most cases these mobile ultrasound systems could be carried by hand and in some cases even operated for a time on battery power alone.
Home ultrasound is the provision of therapeutic ultrasound via the use of a portable or home ultrasound machine. This method of medical ultrasound therapy can be used for various types of pain relief and physical therapy. In physics, the term "ultrasound" [1] applies to all acoustic energy with a frequency above the audible range of human ...
The machine used is called an ultrasound machine, a sonograph or an echograph. The visual image formed using this technique is called an ultrasonogram, a sonogram or an echogram. Ultrasound of carotid artery. Ultrasound is composed of sound waves with frequencies greater than 20,000 Hz, which is the approximate upper threshold of human hearing. [1]
Ultrasound is defined by the American National Standards Institute as "sound at frequencies greater than 20 kHz". In air at atmospheric pressure, ultrasonic waves have wavelengths of 1.9 cm or less. Ultrasound can be generated at very high frequencies; ultrasound is used for sonochemistry at frequencies up to multiple hundreds of kilohertz.
Ultrasound generation by a laser pulse for both the thermoelastic regime and the transition to the plasma regime was examined. [5] By comparing measurements with theoretical predictions, a description of the magnitude and direction of stresses leading to ultrasonic generation was presented for the first time.
