Vibratory data communication between devices
First Claim
1. A device for engaging in communication with other devices, the device comprising:
- a main body;
a processor housed within said main body;
a memory connected to the processor and storing an information signal;
a vibration device housed within said main body and generating vibrations in response to a modulated driving signal; and
a vibration driver operating under the control of said processor and generating the modulated driving signal, wherein said modulated driving signal includes a drive signal modulated by the information signal.

Abstract
A device and method for communicating data from or to a device using vibrations from another device. One of the devices includes a vibrator and the other device includes a sensor for detecting vibrations. The devices are placed in physical contact either directly or through an intermediate medium, such that vibrations generated in the casing of one device are transferred to the casing of the other device. Vibrations are generated by the vibrator in response to a drive signal modulated by an information signal. The modulation may be on-off keying. Modulated vibrations are detected by the sensor in the other device and are demodulated to obtain the information signal.
