Abstract
An apparatus includes a receiver and a controller. The receiver receives a wireless stream with ongoing bursts that are transmitted at recurring periodic intervals. Each burst comprising one or more data packets. The controller controls the receiver to, when the wireless stream is lost for at least a specified quantity of intervals, search for the bursts during each interval, at a successive one of multiple equally-spaced sub-intervals of each interval.
Claims20
An apparatus comprising:
- a receiver to receive a wireless stream comprising ongoing bursts that are transmitted at recurring periodic intervals, each burst comprising one or more data packets;
- and
- a controller configured to, when the wireless stream is lost for at least a specified quantity of intervals, re-establish reception of the wireless stream by searching for the bursts during each interval wherein the searching is performed for sub-intervals of each interval and wherein the searching is initiated at a position within each interval that is a fraction of a total length of each interval and wherein the fraction increases with each successive interval.
A method comprising:
- configuring a receiver to receive a wireless stream comprising ongoing bursts that are transmitted at recurring periodic intervals, each burst comprising one or more data packets;
- and
- configuring the receiver to, when the wireless stream is lost for at least a specified quantity of intervals, re-establish reception of the wireless stream by searching for the bursts during each interval wherein the searching is initiated at a distance into an interval and the distance is increased with each successive interval.
A method comprising:
- configuring a receiver to receive a wireless stream comprising ongoing bursts that are transmitted at recurring periodic intervals, each burst comprising one or more data packets wherein when the receiver is synchronized with the wireless stream, turning the receiver on when the bursts are expected to be received, and turn the receiver off when the bursts are not expected to be received;
- and
- configuring the receiver to, when the wireless stream is lost for at least a specified quantity of intervals, re-establish reception of the wireless stream by searching for the bursts during each interval at a successive one of multiple equally-spaced sub-intervals of each interval.
An apparatus comprising:
- a receiver to receive a wireless stream comprising ongoing bursts that are transmitted at recurring periodic intervals, each burst comprising one or more data packets, the wireless stream conforming to an Enhanced Shockburst (ESB) protocol;
- and
- a controller configured to, when the wireless stream is lost for at least a specified quantity of intervals, re-establish reception of the wireless stream by searching for the bursts during each interval, at a successive one of multiple equally-spaced sub-intervals of each interval;
- and
- when the receiver is synchronized with the wireless stream, turn the receiver on when the bursts are expected to be received, and turn the receiver off when the bursts are not expected to be received, wherein when the data packets of a first of a plurality of bursts is properly received, turn the receiver off during receipt of the remaining plurality of bursts, the plurality of burst comprising a set of redundantly transmitted data packets, wherein the apparatus is a hearing aid powered by a battery.
