Using the Sound Card as a Timer
Experiments in mechanics can often be timed by the sounds they produce. In such cases, digital audio recordings provide a simple way of measuring time intervals with an accuracy comparable to that of photogate timers. We illustrate this with an experiment in the physics of sports: to measure the speed of a hard-kicked soccer ball.
متن کاملIndoor Localization System for Lighting Control
The localization of people and objects in different environments is an essential prerequisite for many applications in navigation, robotics, machine control and monitoring. The limiting factor for many applications is the indoor environment in which the Global Satellite Systems work only partially or cannot function at all. Currently radio frequency (RF) based methods are being increasingly imp...
متن کاملProtecting against Credit Card Forgery with Existing Magnetic Card Readers
Existing magnetic cards adopt plain text to store confidential information, thus being vulnerable to an untrusted credit card reader or a skimming device. To tackle the problem, researchers have proposed many solutions such as integrated circuit card (IC card) and mobile wallets applications [6, 9, 12, 20, 21]; however, none of them can support existing magnetic card readers thereby facing sign...
متن کاملAutomatic Control System for Highway Tunnel Lighting
In order to solve the problems of large energy consumption existing in tunnel lighting control system, an automatic control system of tunnel lighting is designed based on stepless control method. The tunnel lighting control model is established based on “Specifications for Design of Ventilation and Lighting of Highway Tunnel (China)”. Simulation of tunnel lighting control based on the establish...
متن کاملAdaptive Predictive Traffic Timer Control Algorithm
In this paper, we study the optimization of traffic light controllers and present an adaptive, predictive, and statistical optimization algorithm that performs dynamic queue length estimation. The system presented focuses on low power consumption, easy maintenance, and simple construction. The highlights of the system are (1) dynamic queue length estimation for timer delay computation and (2) t...
