Disclosed herein are a Bluetooth device and method for providing a service determined according to Bluetooth PIN. The Bluetooth device includes a storage unit, a reception unit, a control unit, a key generation unit and a transmission unit. The storage unit stores the types of services and security policies according to Bluetooth PIN. The reception unit receives a link key. The control unit searches for a Bluetooth PIN corresponding to the received link key. The key generation unit creates a security key in accordance with the search results and stored security policies. The transmission unit transmits data associated with a service using the created security key.

A method and apparatus for sharing services on a network. The method includes the steps of A) at a first embedded device, transmitting a message requesting at least one service, to at least one embedded device connected with the first embedded device over the network, B) at the first embedded device, receiving code information for implementing the service from the embedded device receiving the message, C) at the first embedded device, executing the code information and implementing the service, and D) at the first embedded device, registering service information on the service when implementation of the service is completed in the step C.
摘要:
There is provided a small and light ozone generating apparatus capable of producing ozone with much less consumption of electric power. The present invention comprises a pulse generator for generating high-voltage pulses and a discharge chamber for inducing electrical discharge in response to the high-voltage pulses. The pulse generator includes an LC circuit for compressing square wave signals and generating impulses. The use of impulse greatly reduces electric power consumption and volume of ozone generating apparatus. Electrical discharge takes place between an electrode plate and grounded chamber wall. A sheet of oxide dielectric covers the chamber wall to prevent corrosion of chamber wall.
