Abstract

A communication device is included in a daisy chain connection. A receiver receives a first signal from a preceding device in the daisy chain connection. A transmitter transmits the first signal received in the receiver to a succeeding device in the daisy chain connection. An acceptor accepts a second signal starting from the communication device. The transmitter transmits the second signal accepted in the acceptor to the succeeding device at a transmission rate higher than a transmission rate of the first signal received in the receiver.

First claim

What is claimed is:

1 . A communication device included in a daisy chain connection, the communication device comprising:
a receiver that receives a first signal from a preceding device in the daisy chain connection; a transmitter that transmits the first signal received in the receiver to a succeeding device in the daisy chain connection; and an acceptor that accepts a second signal starting from the communication device, wherein the transmitter transmits the second signal to the succeeding device at a transmission rate higher than a transmission rate of the first signal.

2 . The communication device according to claim 1 , wherein the transmitter maintains the transmission rate of the first signal when transmitting the first signal received in the receiver to the succeeding device in the daisy chain connection.

3 . The communication device according to claim 1 , wherein the acceptor determines a transmission rate.

4 . The communication device according to claim 2 , wherein the acceptor determines a transmission rate.

5 . The communication device according to claim 1 , wherein
the communication device is connected to a battery pack, and the second signal accepted in the acceptor includes information regarding the battery pack.

6 . The communication device according to claim 2 , wherein
the communication device is connected to a battery pack, and the second signal accepted in the acceptor includes information regarding the battery pack.

7 . The communication device according to claim 3 , wherein
the communication device is connected to a battery pack, and the second signal accepted in the acceptor includes information regarding the battery pack.

8 . The communication device according to claim 4 , wherein
the communication device is connected to a battery pack, and the second signal accepted in the acceptor includes information regarding the battery pack.

9 . The communication device according to claim 1 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

10 . The communication device according to claim 2 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

11 . The communication device according to claim 3 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

12 . The communication device according to claim 4 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

13 . The communication device according to claim 5 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

14 . The communication device according to claim 6 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

15 . The communication device according to claim 7 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

16 . The communication device according to claim 8 , wherein a reference signal for identifying a transmission rate, which signal has a common value, is included in the first signal and the second signal transmitted from the transmitter.

17 . A receiving device comprising:
a receiver that receives a signal from each of a plurality of communication devices included in a daisy chain connection, for which signal a plurality of kinds of transmission rates is used; and a processor that processes the signal received in the receiver, wherein
in the signal received in the receiver, a reference signal for identifying a transmission rate, which signal has a common value irrespective of the transmission rate, is included, and
the receiver receives the signal at each of the plurality of kinds of transmission rates, and selects a transmission rate at which the reference signal for identifying a transmission rate has been detected.

18 . A communication system comprising:
a management device; and a plurality of communication devices daisy-chained from the management device, wherein each of the plurality of communication devices transfers a signal received from a preceding device in the daisy chain connection to a succeeding device in the daisy chain connection, and transmits, to the succeeding device, a signal starting from the communication device at a transmission rate higher than a transmission rate used for the transfer.

19 . The communication system according to claim 18 , wherein
a reference signal for identifying a transmission rate, which signal has a common value irrespective of the transmission rate, is included in the signal in the daisy chain connection, and the management device receives the signal at each of a plurality of kinds of transmission rates used in the daisy chain connection, and selects a transmission rate at which the reference signal for identifying a transmission rate has been detected.
