`Claims 2 and 59 of U.S. Patent No. 8,023,580
`(EX1001, 7:53-8:24 and 11:51-12:17)
`
`
`
`Claim 2. *[A communication device capable of communicating according to a
`master/slave relationship in which a slave communication from a slave to a master
`occurs in response to a master communication from the master to the slave, the
`device comprising:
`
`a transceiver, in the role of the master according to the master/slave relationship,
`for sending at least transmissions modulated using at least two types of
`modulation methods, wherein the at least two types of modulation methods
`comprise a first modulation method and a second modulation method, wherein
`the second modulation method is of a different type than the first modulation
`method, wherein each transmission comprises a group of transmission
`sequences, wherein each group of transmission sequences is structured with
`at least a first portion and a payload portion wherein first information in the
`first portion indicates at least which of the first modulation method and the
`second modulation method is used for modulating second information in the
`payload portion, wherein at least one group of transmission sequences is
`addressed for an intended destination of the payload portion, and wherein for
`the at least one group of transmission sequences:
`
`the first information for said at least one group of transmission sequences
`comprises a first sequence, in the first portion and modulated according to the
`first modulation method, wherein the first sequence indicates an impending
`change from the first modulation method to the second modulation method,
`and
`
`the second information for said at least one group of transmission sequences
`comprises a second sequence that is modulated according to the second
`modulation method, wherein the second sequence is transmitted after the first
`sequence],
`
`wherein the transceiver is configured to transmit a third sequence after the second
`sequence, wherein the third sequence is transmitted in the first modulation
`method and indicates that communication from the master to the slave has
`reverted to the first modulation method.
`
`* Bracketed information is incorporated from Claim 1.

`
`
`
`Claim 59. *[A communication device capable of communicating according to a
`master/slave relationship in which a slave message from a slave to a master occurs
`in response to a master message from the master to the slave, the device comprising:
`
`a transceiver, in the role of the master according to the master/slave relationship,
`capable of transmitting using at least two types of modulation methods,
`wherein the at least two types of modulation methods comprise a first
`modulation method and a second modulation method, wherein the second
`modulation method is of a different type than the first modulation method,
`and wherein the transceiver is configured to transmit messages with:
`
`a first sequence, in the first modulation method, that indicates at least which of
`the first modulation method and the second modulation method is used for
`modulating a second sequence, wherein, in at least one message, the first
`sequence indicates an impending change from the first modulation method to
`the second modulation method, and wherein the at least one message is
`addressed for an intended destination of the second sequence, and
`
`the second sequence, modulated in accordance with the modulation method
`indicated by the first sequence and, in the at least one message, modulated
`using the second modulation method, wherein the second sequence is
`transmitted after the first sequence],
`
`wherein the transceiver is configured to transmit a third sequence after the second
`sequence, wherein the third sequence is transmitted in the first modulation
`method and indicates that communication from the master to the slave has
`reverted to the first modulation method.
`
`* Bracketed information is incorporated from Claim 58.
