EVISION Obstacle Detector
MS 1528
-
Obstacle Detector is a distance-measuring system based on ultrasonic sound utilizing the LPC2364FBD100. The system transmits a burst of ultrasonic sound waves towards the subject and then receives the corresponding echo. The LPC2364FBD100 integrated analog comparator is used to detect the arrival of the echo to the system. The time taken for the ultrasonic burst to travel the distance from the system to the subject and back to the system is accurately measured by the LPC2364FBD100. Assuming the speed of sound in air at room temperature to be 1100 ft/s, the LPC2364FBD100 computes the distance between the system and the subject and gives the information to buzzer. The minimum distance that this system can measure is eight inches and is limited by the transmitter’s transducer settling-time. The maximum distance that can be measured is 2 meter. The amplitude of the echo depends on the reflecting material, shape, and size. Sound-absorbing targets such as carpets and reflecting surfaces less than two square feet in area reflect poorly. The maximum measurable range is lower for such subjects. If the amplitude of the echo received by the system is so low that it is not detectable by the Comparator. This system is mainly used to replace normal sticks for the visually impaired (blind) peoples. This unit has standard USB 2.0 for mobile interface and has android application for user interface

Infrasound Measurements
-
Is sound that is lower in frequency than 20 Hz (hertz) or cycles per second, the "normal" limit of human hearing. Hearing becomes gradually less sensitive as frequency decreases, so for humans to perceive infrasound, the sound pressure must be sufficiently high. The ear is the primary organ for sensing infrasound, but at higher intensities it is possible to feel infrasound vibrations in various parts of the body.

Acoustic quality, vehicle dynamics and stability, and driver comfort play an increasingly important role in the development of new chassis and suspension systems – both passive and active. Noises in suspension components can cause customer dissatisfaction and lead to high warranty costs and are difficult to diagnose especially on historically-used, noisy hydraulic test rigs. The MB Suspension Component Test Rig (SCTR) enables dynamic simulation of real road excitations and synthesized waveforms, performing industry-standard Force-Velocity and Force-Displacement tests and low speed friction tests, and assessing other NVH and structure-borne noises for comprehensive performance characterization and sound and vibration analyses on a wide variety of chassis components.

SparkFun ToF Range Finder Breakout for VL6180
12784
-
This is the SparkFun "Time-of-Flight" Range Finder, a breakout for the VL6180 distance sensor. Unlike most distance sensors that rely reflected light intensity or reflected angles to determine range, the VL6180 uses a precise clock to measure the time it takes light to bounce back from a surface. This affords the ToF Range Finder and VL6180 a great benefit over other methods because it can be much more accurate and more immune to noise. Does this technology sound familiar? Well it should, it's the same means cellphones use to detect when the caller is holding their phone to their ear.

Sound Level Meters
-
A sound level meter is a measuring instrument used to assess noise or sound levels by measuring sound pressure. Often referred to as a sound pressure level (SPL) meter, decibel (dB) meter, noise meter or noise dosimeter, asound level meter uses a microphone to capture sound. The sound is then evaluated within the sound level meter and acoustic measurement values are shown on the display of the sound level meter. The most common unit of acoustic measurement for sound is the decibel (dB); however, some sound level meter devices also determine the equivalent continuous sound level (Leq) and other acoustic parameters. With a portable sound level meter, industrial hygiene and workplace safety professionals can measure sound levels in multiple locations to ensure environmental conditions fall within recommended exposure limits (RELs). Some sound level meter devices can be permanently installed for continuous monitoring of sound levels at a work or job site. PCE sound level meter products are lightweight, easy-to-use and manufactured in accordance with the highest industrial standards.
