Abstract:
A Bluetooth data/control message transmission module, an interaction device and a method thereof are provided in the present invention. The Bluetooth data/control message transmission module connects to a mobile device with Bluetooth. The Bluetooth data/control message transmission module includes a process unit, a modulation module and a Bluetooth module. The process unit is for providing a digital data. The modulation module receives the digital data and modulates the digital data with a analog carrier signal to generate a modulation signal whose frequency is lower than 8 KHz. The Bluetooth module uses a headset profile to link with the mobile device, wherein the mobile device serves the Bluetooth module as a headset. The Bluetooth module samples the modulation signal, to serve the sampled modulation signal as a voice signal to send to the mobile device through the Bluetooth protocol.
Abstract:
An interactive amusement system, interactive wearing system and a data transmission circuit for biological contact are provided in the present invention. The interactive wearing system includes a first wearing device and a second wearing device. The first and the second wearing devices are includes a contact conductor for respectively contacting with the users. When a first user wears the first wearing device and a second user wears the second wearing device, and the first user touches the second user, a secret message that has been set into the first wearing device by the first user is transmitted to the second wearing device.
Abstract:
A method for unlocking a door, a method for renting asset and a system thereof are provided in the present invention. The door includes an audio receiver, and the method includes the steps of: storing a unlock sequence into a mobile device; performing a audio modulation to generates a audio modulation voiceprint signal, wherein the frequency range of the audio modulation voiceprint signal is in the audio frequency; playing the audio modulation voiceprint signal by using the speaker of the mobile device; when the audio receiver receives the audio modulation voiceprint signal, the method further includes: performing a audio demodulation to obtain the unlock sequence; and determining whether the door is unlock or not according to the unlock sequence.
