In the development of LSI for ultrasound diagnostic devices, we would like to introduce a case where our system analog technology was applied. The challenges were to control approximately 2000 transducers at a size that could fit into the esophagus and to minimize power consumption to prevent burns. To address this, we arranged the transmission and reception circuits connected to the ultrasound transducers (piezo elements) in an array configuration to achieve beamforming. This allowed us to suppress heat generation to an extreme low power consumption. 【Case Overview】 ■ Customer Challenges - Control approximately 2000 transducers at a size that can fit into the esophagus - Minimize power consumption to prevent burns ■ Achievements - Equipped with 1900 transceivers (transmission and reception circuits) in a size of approximately 10mm x 10mm - Incorporated beamforming functionality with a power consumption of 2W *For more details, please refer to the PDF document or feel free to contact us.

The "D-WATCHER BORDER" is an IoT ultrasonic threshold sensor that remotely monitors the quantities of waste, materials, and water levels. For the "arterial industries" that produce goods, such as manufacturing, and the "venous industries" that collect, recycle, reuse, process, and dispose of waste, it is essential to maintain a balance and collaboration between both for smooth circulation. This product, installed on numerous waste collection carts dispersed throughout a large facility, detects when they are full. This enables the elimination of waste and allows for appropriate collection. 【Main Specifications (Partial)】 ■Dimensions: W88×H33×D146mm ■Weight: 260g ■Operating Temperature Range: 15–35℃ (no condensation) ■Power Supply: 2 AA batteries ■Charging Method: None *For more details, please refer to the PDF document or feel free to contact us.
