Abstract: Systems and methods for measuring flow velocities, including ultrasound systems, are provided. A Doppler angle between a direction of ultrasound signals and an axis of a flow may be estimated to improve the accuracy of the flow velocity estimation that is based on Doppler effects. A sensor may be mounted on or in an ultrasound probe to obtain a reference orientation of the ultrasound probe and an orientation of the ultrasound probe relative to the reference orientation when the ultrasound probe is moved to other positions. The Doppler angle may be estimated based on the orientation of the ultrasound probe.

Abstract: A medication concentration detecting device includes a medicine container, a three-way pipe, a light emitting member, a first light receiver and a processor. The medicine container has a chamber configured for accommodating nebulized medicine. The three-way pipe has a passageway connected to the chamber for the nebulized medicine to flow along the passageway. The light emitting member is disposed on the three-way pipe and configured for emitting a light beam toward the passageway. The first light receiver is disposed on the three-way pipe and configured for receiving the light beam and outputting a luminous flux signal. The processor is connected to the first light receiver and configured for calculating a luminous flux reference value according to the luminous flux signal. The luminous flux reference value is used for determining whether outputs a low nebulized medicine concentration warning.
