nike + ipod exercise - battery power storage
Since its storage, software, and battery power supply are located on the iPod Nano, the receiver of the sports kit is a little simpler than the transmitter.
It plugs into the Nano's docking station connection through multiple plugspin connector --
These pins transmit data and power back and forth between the two devices.
The receiver itself has only a few components, including the processor, the receiver, the antenna, and several resistors and capacitors.
The first time someone uses the Nike iPod system, the sensor is connected to the receiver.
The receiver learns the identification code that identifies a particular sensor.
So, in the absence of interference from the Nike iPod sensor, multiple people can run together.
If several people in a home use the same but different sensors, the receiver can learn to recognize each sensor, and the Nano can store different settings for each user.
This system is flexible, 60-foot (18. 2-meter)
The range of transmitters makes it unlikely that two parts of the system will lose contact with each other.
However, the relatively long distance of the sensor has raised concerns about the privacy of the Nike system.
In November of 2006, Washington University computer science and engineering department release your files detailed (how to in Nike iPod Sport Kit can be used for evil objective.
The paper states that the transmitter sends data whether the receiver is nearby or even plugged into the iPod.
According to the author of the paper, this ongoing dissemination may be used to infringe upon the privacy of a person.
This paper presents several scenarios where the motion kit can be used to track a person.
There are some technical requirements for these scenarios.
In order to successfully track people who use the sports kit, the perpetrator must: several media have some knowledge of the story and some media claim that the sports kit is easyto-
RFID systems that threaten people's privacy.
However, the Nike sports kit is currently facing a different problem ---
Electronics maker PhatRat in February 2007 sued Apple and Nike for patent infringement.
PhatRat claims that the sports kit infringes its wireless performance
Tracking technology.
