Systems and Methods for Dampening TDMA Interference

摘要

Systems and methods are disclosed which relate to mitigating the detrimental effects of interference to electronic devices from mobile telephones utilizing any form of time-domain multiplexing technology. A wireless transmitter inside the mobile telephone broadcasts a warning transmission which can be received by affected devices. Once the warning transmission is received by an affected device, the device activates a blanking circuit comprising an actuator and a switch or switches. The switches open for the duration of the interference so that the user does not receive undesired output such as: noise through a speaker, noise through a microphone, or other interference with electrical signals.

主权项

1. A mobile telephone comprising:
a radio frequency transmitter configured to transmit a radio frequency transmission burst; a protocol stack; a short range communication formatter configured to receive, from the protocol stack prior to a transmission of the radio frequency transmission burst, an indication of the transmission of the radio frequency transmission burst; and a short range communication transmitter associated with the short range communication formatter, the short range communication transmitter configured to broadcast, to a receiver associated with an affected device prior to the transmission of the radio frequency transmission burst, a warning transmission comprising a timing and a duration associated with the transmission of the radio frequency transmission burst for use by the affected device to time blanking of the affected device, wherein a duration of blanking of the affected device spans an entire pulse width of the radio frequency transmission burst based on the timing and the duration associated with the transmission of the radio frequency transmission burst provided by the warning transmission.
