摘要： A fluid injector system includes at least one injector for pressurizing and delivering at least one fluid from at least one fluid reservoir, at least one fluid path section in fluid communication with the at least one injector and having a predetermined index of refraction, and a first proximal sensor and a first distal sensor arranged along the at least one fluid path section. Each of the first proximal sensor and the first distal sensor includes an emitter configured to emit light through the at least one fluid path section, and a detector configured to receive the light emitted through the at least one fluid path section and generate an electrical signal based on the received light. The fluid injector system further includes at least one processor programmed or configured to determine, based on a difference in the electrical signals generated by the first proximal sensor and the first distal sensor, at least one property of a content of the at least one fluid path section.

摘要： An apparatus and method for determining fluid flow (e.g., sterile media flow, filtrate flow, etc.) through tubing is provided. The apparatus includes an air source, a flow valve, a first sensor, a second sensor, and a media tubing section extending between the first sensor and the second sensor. In operation, air from the air source is introduced by the flow valve into a fluid flow to create a lead line of fluid immediately following the introduced air. As the lead line of fluid passes each sensor, the sensors are used to determine a time between when the lead line passes the first sensor and the second sensor and that determined elapsed time is used, along with a determined volume of the media tubing section to determine the rate of flow of the fluid flow.

摘要： Methods and apparatuses for beam pattern stabilization are provided. A method may include processing an output of a gyroscopic sensor to generate a plurality of first phase corrections for a first time interval and a plurality of second phase corrections for a second time interval. The method may further include measuring respective signal propagation characteristics between each antenna element of the array and each of a first and second subscriber module for the first time interval. The method may further include forming, based on the measured respective signal propagation characteristics, the plurality of first phase corrections, and the plurality of second phase corrections, a MU-MIMO beam pattern for the second time interval having a main lobe towards the first subscriber module and a null towards the second subscriber module, whereby to correct for a change in orientation of the array between the first time interval and the second time interval.

摘要： Described is an ultrasonic anemometer (7) as well as a method for determination of at least one component of a wind velocity vector and/or a velocity of sound with at least one sound transducer at least temporarily working as a transmitter (1, 2, 3, 4, 5, 6, 15, 16) with a sound emission surface for emitting sound waves and at least one sound transducer at least temporarily working as a receiver (1, 2, 3, 4, 5, 6, 15, 16) with a sound detection surface for at least partially receiving the emitted sound waves, and with an evaluation unit, which, based on a recorded transit time, which the sound waves require on a measuring section located between the sound emission surface of the at least one transmitter and the sound detection surface of the at least one receiver to cover the distance of this measuring section, determines at least one component of a wind velocity vector and/or the velocity of sound.The technical solution described is characterized by at least one measuring section between a first sound emission surface of a first transmitter and a first sound detection surface of a first receiver being arranged approximately vertical to the earth's surface and the first sound emission surface and/or the first sound detection surface being inclined compared to the horizontal.

摘要： Systems and methods for determining gas velocity based on phase differences of signals from two or more interaction paths in a gas analyzer system. A laser source, which can provide access to an absorption gas line, is expanded, or is split into two or more beams. These beams can be used to create two (or more) parallel sampling paths separated by a known distance. Gas travelling in the plane of the two beams of light will pass through the optical paths at two (or more) different times creating very similar signals that will be out of phase with each other. The amount of phase difference will be inversely proportional to the velocity of the gas.

摘要： Systems and methods for displaying to a tilt rotor aircraft pilot an optimum nacelle position and/or automatically controlling movement of the nacelles for the pilot. An automatic nacelle conversion function employs an active flight director speed mode to provide a current desired speed and a final speed. When the automatic nacelle conversion function is in a passive (uncoupled) mode of operation, the pilot follows visual cues, manually achieving the commanded nacelle position by rotating a thumbwheel. When in an active (coupled) mode of operation, the automatic nacelle conversion function provides a fully automatic nacelle controller requiring no pilot input. This automatic nacelle controller provides a variable nacelle rate along with several angle versus speed schedules tailored for different guidance speed modes and a wide range of aircraft configurations. The automatic nacelle conversion function is improved though the inclusion of altitude, rate of climb, and deceleration rate commands.
摘要翻译： 用于向倾斜转子飞行器飞行员显示最佳机舱位置和/或自动控制飞行员机舱的运动的系统和方法。 自动机舱转换功能采用主动飞行导向器速度模式来提供当前期望速度和最终速度。 当自动机舱转换功能处于被动（非耦合）操作模式时，飞行员遵循视觉提示，通过旋转指轮手动实现命令的机舱位置。 当处于主动（耦合）操作模式时，自动机舱转换功能提供不需要导频输入的全自动机舱控制器。 该自动机舱控制器提供了可变机舱速率以及为不同的引导速度模式和各种飞行器配置量身定制的几个角度对速度计划。 尽管包括高度，爬升率和减速率指令，机舱自动换向功能也得到了改善。
