Universal Detachable Infrared Transmitter

Lot Summary

This patent portfolio discloses a universal transmitter that couples with communication devices. Short range or Infrared, wireless transmission of audio is a convenient way for users to privately listen to sound sources such as television, or media players. Typically, such privacy listening systems requires earphones mounted into a headset that contains the receiver circuitry and power supply. Conventional communication systems include integral or external receivers, and integral transmitters. However, the external wireless earpiece receiver functions only with a particular type of transmitter integrated into the communication device. Further, wireless communication systems such as infrared systems require considerable power to operate.

Value Proposition: This patent portfolio discloses a portable communication system that includes a universal IR transmitter communicating with an IR wireless receiver. The transmitter is removably coupled with a communication device (e.g., a mobile phone) and includes a microphone, modulation circuitry, and an IR light emitting device. Sound output from a user is picked up by the microphone, converted to electric pulses (by using the modulation circuitry) and then transmitted as IR light signals to the IR receiver. The IR receiver then converts the electric pulses into electric signals, which are further converted to audio signals that are outputted from the speakers. This portable communication system (or the transmitter) can be connected to an audio port of a communication device (e.g., a mobile phone). The signals from the communication device are sent to a receiver (e.g., a wireless headset) through this transmitter providing privacy to the users. Further, pulse code modulation is used in the system for providing very low power consumption while achieving high quality of communication.
