A torsional reed reference fluidic oscillator operating within 0.1% of the desired frequency over a temperature range of -65° to + 165. degree.F and an operating pressure of from 1 to 4 psi. The oscillator includes a torsional reed fluidic amplifier and fluidic feedback means for converting ...
Its distinctive characteristic, however, is the fact that a pendulum mass is connected to an intermediatedamper massand functions as an additional damper. A standard damper comprises a spring mass oscillator that responds to a specificexcitation frequency, which is determined byspring stiffnessand mass...
the outside wall of a fluid-carrying vessel. Ultrasonic energy consists of a train of shortbursts of sinusoidal waveforms at a frequency between 0.5 and 20MHz. This frequency range is described as ultrasonic because it is outside the range of human hearing. The flow velocity,v, is given by...
The extent of lock-in gets severely truncated as compared to the one for a bluff oscillator; it spans just over an extremely narrow U* range of 3.5 to 4.2. The onset and closure of lock-in are marked with the oscillation frequency attaining its maximum and minimum, respectively. ...
where mC is the effective mass of the microcavity photons, ΩR is the Rabi frequency coupling the photonic ψC and excitonic ψX fields, γC and γX are the associated decay rates and g is the nonlinear interaction term in the exciton component. Further details are given in the ‘Methods...
In this work, utilizing a characteristic oscillation of adjacent interfaces between two immiscible fluids in a microfluidic platform, we discover that the system can act as a coupled oscillator, notably showing spontaneous in-phase synchronization of droplet breakup. With this observation of in-phase ...
h. the compliance of said working fluid and the reactive component of said load being arranged to resonate at the frequency of the oscillations, determined by said dissipative and reactive components and said gain. 10.A fluidic oscillator according to claim 8, in which said working fluid is ...
12, calibration is accomplished by adjustment of oscillator 116 as will be described. Operation is then started when power is supplied. Circuit 117 then supplies an alternating output signal to squarer 108 which varies in frequency over a range of the instrument. When resonance is found, ...
In general, system A constitutes a bellows-actuated fluid oscillator for cycling fluid at high frequency, e.g., from about 200 to about 2,600 cycles per minute, in a completely closed condition for repeatedly exposing the sample under test to the action of an oscillatory fluid on opposite si...
The transmitting probe is coupled to an oscillator which is controlled to sweep a predetermined frequency range for generating one or more TM.sub. 01q resonant modes within the cylinder cavity. A threshold detector and a peak detector are coupled to the receiving probe for detecting occurrence of...
