Controller The controller‚ also known as the transmitter‚ for the Alias by LaTrax looks just like a PlayStation controller‚ and is just as easy to use and comfortable. Interestingly enough‚ a cue from console controllers was taken to ensure that the controller is comfortable enough to be used for longer periods of time‚ after the drone has been charged multiple times‚ of course‚ especially when you look at the pads that go onto the thumb sticks or joysticks. The precision gimbals are tuned for

Pilot trolley method for trains AIM: To design a auto pilot trolley method for trains. Base Technology: EMBEDDED Abstract: It is a very useful project. By using this we can reduce the more train accident. The trolley is communicating with the train using ISM based RF signal. 432.92 MHz frequency signal is used for communication. As we do the project we use this frequency. It will sense the object using the IR signal‚ bomb is detected using metal detector‚ track open is sensed using limit

Radio-controlled car Radio-controlled (or R/C) cars are usually categorized as either "toy" or "hobby" grade. Remote control vehicles are usually of one of two types: control of a vehicle by radio transmission or by a wire connecting between the transmitter and car. This article focuses on the radio-controlled vehicle category‚ both toy and hobby grades.Cars are powered by various sources. Electric cars are powered by small but powerful electric motors and rechargeable nickel-cadmium‚ nickel metal

Submersible Pump Application The system consists of a submersible pump controlled by a Danfoss VLT AQUA Drive and a pressure transmitter. The transmitter gives a 4-20 mA feedback signal to the VLT AQUA Drive‚ which keeps a constant pressure by controlling the speed of the pump. To design a drive for a submersible pump application‚ there are a few important issues to take into consideration. Therefore the drive used must be chosen according to motor current. 1. The motor is a so called “Can motor”

CHAPTER 2 MULTIPLE ACCESS A limited amount of bandwidth is allocated for wireless services. A wireless system is required to accommodate as many users as possible by effectively sharing the limited bandwidth. Therefore‚ in the field of communications‚ the term multiple access could be defined as a means of allowing multiple users to simultaneously share the finite bandwidth with least possible degradation in the performance of the system. There are several techniques how multiple accessing can
