Controlling transmit duty cycle by position of cover

A device for transmitting packets of a message during an assigned time slot of cycles of a time-division protocol, comprising:

• a housing, the housing having at least two portions, the at least two portions being movable to each other into a first position and a second position;
• a controller within the housing, the controller adapted to associate a first transmit duty cycle with the first position and a second transmit duty cycle with the second position, wherein the first transmit duty cycle comprises message packet transmission in the assigned time slot of adjacent cycles of the protocol, and wherein the second transmit duty cycle comprises message packet transmission in the assigned time slot of at least every 2nd cycle of the protocol;
• and
• a transmitter coupled to the controller, the controller adapted to cause the transmitter to operate at the first transmit duty cycle when the at least two portions of housing are in the first position and to operate at the second transmit duty cycle when the at least two portions of housing are in the second position.

In a device having a transmitter and a housing, the housing comprised of two or more portions, at least one portion of the two or more portions movable into a plurality of positions, a method of controlling a transmit duty cycle of the transmitter by a position of the at least one portion of the two or more portions of the housing, comprising the steps of:

• storing in the device a plurality of transmit duty cycles of the transmitter, a first transmit duty cycle associated with a first position of the plurality of positions of the at least one portion of the two or more portions of the housing, a second transmit duty cycle associated with a second position of the plurality of positions of the at least one portion of the two or more portions of the housing,
• wherein the first transmit duty cycle comprises message packet transmission in the assigned time slot of adjacent cycles of the protocol, and wherein the second transmit duty cycle comprises message packet transmission in the assigned time slot of at least every 2nd cycle of the protocol;
• determining a current position is the first position of the at least one portion of the two or more portions of the housing;
• in response to the first position, setting the transmitter to operate at the first transmit duty cycle;
• changing the position of the at least one portion of the two or more portions of the housing to the second position;
• and
• in response to the second position, setting the transmitter to operate at the second transmit duty cycle.

In a device having a transmitter and a housing, the housing comprised of two or more portions, the portions capable of being moved into more than one position relative to each other, a method comprising the steps of:

• storing in the device a plurality of transmit duty cycles of the transmitter, a first stored transmit duty cycle associated with a first position, a second stored transmit duty cycle associated with a second position,
• wherein the first transmit duty cycle comprises message packet transmission in the assigned time slot of adjacent cycles of the protocol, and wherein the second transmit duty cycle comprises message packet transmission in the assigned time slot of at least every 2nd cycle of the protocol;
• determining a current position of the portions is the first position;
• in response to the first position, setting the transmitter to operate at the first stored transmit duty cycle;
• transmitting at the first transmit duty cycle;
• changing the current position of the portions to the second position;
• in response to the second position, setting the transmitter to operate at the second stored transmit duty cycle;
• and
• transmitting at the second transmit duty cycle.
