    • Calibrating a posture detector for a patient's body involves measuring outputs of one or more sensors disposed in relation to the patient's body while the patient assumes a plurality of positions. A transfer matrix is formed having coefficients corresponding to the measured outputs. The transfer matrix defines a relationship between a coordinate system of the one or more sensors and a coordinate system of the patient's body. The body coordinate system is used as a reference coordinate system for posture detection. Posture, including tilt and/or tilt angle, may be determined based on first and second rotational angles defined in relation to the body coordinate system.
    • 校准患者身体的姿势检测器涉及测量在患者承担多个位置时相对于患者身体设置的一个或多个传感器的输出。 形成具有对应于测量输出的系数的传送矩阵。 传输矩阵定义一个或多个传感器的坐标系与患者身体的坐标系之间的关系。 身体坐标系用作姿势检测的参考坐标系。 基于相对于身体坐标系定义的第一和第二旋转角度,可以确定包括倾斜和/或倾斜角度的姿势。

    • An ultrasonic transducer is disclosed, which includes one or a plurality of ultrasonic emitting units. Wavefronts of the ultrasonic waves emitted by the one or the plurality of ultrasonic emitting units are sphere surfaces with uniform radius, and the one or the plurality of ultrasonic emitting units can reflect ultrasound. The one ultrasonic emitting unit is configured to form a spherical resonant cavity, or the plurality of ultrasonic emitting units are configured to form a spherical resonant cavity collectively. An internal cavity of the spherical resonant cavity has a spherical shell shape or a cross-sectional spherical shell shape with a spherical center therein. The ultrasonic waves emitted by the one or the plurality of ultrasonic emitting units are focused on an area in which the spherical center of the spherical resonant cavity is located. The ultrasonic transducer not only can be provided with a large ultrasonic emitting area and a great focusing gain that render the energy of the ultrasonic focus enhanced dramatically, but also can be free from the influence of work frequency of an ultrasonic source.
    • 公开了一种超声换能器,其包括一个或多个超声波发射单元。 由一个或多个超声波发射单元发射的超声波的波前是具有均匀半径的球面,并且一个或多个超声波发射单元可以反射超声波。 一个超声波发射单元被配置为形成球面谐振腔,或者多个超声波发射单元被配置为共同形成球面谐振腔。 球形谐振腔的内腔具有球形壳体形状或截面球形壳体形状,其中具有球形中心。 由一个或多个超声波发射单元发射的超声波聚焦在球面谐振腔的球形中心所在的区域上。 超声波换能器不仅可以提供大的超声波发射区域和大的聚焦增益,使超声波的能量显着提高,而且可以免受超声波源的工作频率的影响。

    • A system for measuring parameters in a container is disclosed. A container has a solution. A protective layer is deposited over at least one sensor and at least one wall of the container, where the protective layer is attached to the wall of the container to form a seal between the container and the at least one sensor. The at least one sensor is configured to have an operable electromagnetic field based on a thickness of the container and the protective layer. The at least one sensor in conjunction with a tag is in proximity to an impedance analyzer and a reader that constitute a measurement device. The at least one sensor is configured to determine at least one parameter of the solution. The tag is configured to provide a digital ID associated with the at least one sensor, where the container is in proximity to the reader and an impedance analyzer. The impedance analyzer is configured to receive a given range of frequencies from the at least one sensor based on the measured complex impedance over the given range of frequencies.
