LOW POWER INTERMITTENT MESSAGING FOR HEARING ASSISTANCE DEVICES

摘要

The present subject matter includes a system for communications between a transmitter and a receiver. In various embodiments, the system uses a sleep interval to allow the receiver to go to sleep between wake up times to “sniff” for transmissions from the transmitter. The system adjusts the length of the preamble of the transmitted signal or a repetition of packets to allow the receiver to detect a transmitted signal based on drift in the clocks of the system. In various embodiments, a receive channel is changed if a signal is not received at a prior channel selection. In various embodiments, the transmission is determined by detection of an event. In various embodiments, the event is an ear-to-ear event. In various embodiments, the receiver and transmitter are in opposite hearing aids adapted to be worn by one wearer.

主权项

1. A method for communications between a transmitter having a first clock and a receiver having a second clock, the method comprising:
synchronizing the first clock and the second clock at a synchronization time; determining a time interval between the synchronization time and a transmission time of a transmission; calculating a drift window using a potential drift amount between the first clock and the second clock over the time interval; transmitting the transmission with the transmitter, the transmission including a repetition of packets having a duration based on the drift window; and receiving with the receiver using a reception window that is adjustable based on the drift window.
