The built-in ultrasonic flow measurement of stand pipe based on correlation method is designed (
In industrial production, flow measurement is a widely used physical quantity measurement. Under specific circumstances, such as when vertical externally positioned installation probes are required for challenging pipelines like oil wells, it is necessary to design instruments and equipment to...
Tactile feedback solutions using piezoelectric actuators
Implementing tactile (haptic) feedback in consumer electronic devices enhances the user experience by providing a sense of touch in user interface design. It represents the latest major interface innovation in smartphones and other portable consumer electronic devices. Various haptic technologies...
Hotel ultrasonic interference detection system based on ultrasonic probe DSP interference US0012
The circuit consists of the US0012 ultrasonic interference detection system, as illustrated in the accompanying figure. When the SEL40k termination is set to high, it selects a clock frequency of 40kHz. The US0012 module can perform several tasks: it provides...
TV_CONTROL_RECEIVER
Utilizes a barium titanate transducer as a microphone, tuned with a 20 mH coil to generate peaks at control frequencies of 38.5 kHz and 41.5 kHz. A balanced discriminator detects the two ultrasonic tones. A frequency shift in the continuous...
Discrete circuit elements constituting the ultrasonic transmitter
The discrete components ultrasonic transmitting circuit T/R-40-16 is capable of emitting a series of ultrasonic signals at a frequency of 40 kHz. This circuit operates at a voltage of 9V, with an operating current of 25 mA, and can control...
ultrasonic motion detector
The circuit described exhibits high sensitivity to movement, capable of detecting even slight air movements such as hot air rising or wind blowing when the trimpot is adjusted to a sensitive position. The transmitter emits a continuous ultrasonic tone at...
Mole Deterrent Teardown
A healthy population of moles exists in the vicinity, prompting the purchase of four inexpensive ultrasonic mole deterrents from eBay to encourage them to relocate. The devices emit a frequency that is unpleasant to moles, leading them to vacate the...
proximity alarm circuit
Inverters U1a and U1b are connected in a simple RC oscillator circuit. The frequency is determined by the values of R1, C1, C2, and the internal characteristics of the integrated circuit. As long as the circuit is oscillating, a positive...
Gate automatic lamp circuit
The circuit utilizes multiple integrated circuits to form an automatic lighting device that is activated by door and window sensors. It includes CD4093 digital integrated circuits, a relay, and a power supply circuit. The system typically remains closed when a...
