Abstract
A position detection device is operated in a detection mode in which a multiprotocol simultaneous activation uplink signal is transmitted. The multiprotocol simultaneous activation uplink signal is obtained by adding, to a first portion configured to activate a stylus using a first protocol, subsequent data for activating the stylus using a second protocol different from the first protocol.
Claims17
A position detection device comprising:
- a detection mode wherein a multiprotocol simultaneous activation uplink signal is transmitted, which is obtained by adding, to a first portion configured to activate a stylus using a first protocol, subsequent data for activating the stylus using a second protocol different from the first protocol.
A stylus comprising:
- a first determination section that determines whether or not a first uplink signal configured to activate the stylus using a first protocol is included in a received signal;
- a second determination section that determines whether or not first subsequent data for activating the stylus using a second protocol different from the first protocol is added to the first uplink signal, in a case where the first determination section determines that the first uplink signal is included in the received signal;
- and
- a transmission section that transmits a downlink signal using the second protocol, in a case where the second determination section determines that the first subsequent data is added to the first uplink signal.
1 more element
A position detection device configured to:
- set a reservation time in a frame indicated by a second uplink signal configured to activate a stylus using a second protocol of a frame system, and
- transmit, in the reservation time, a first uplink signal configured to activate the stylus using a first protocol different from the second protocol.
A stylus comprising:
- setting information indicating either one of a first protocol and a second protocol that are different from each other;
- wherein, in response to receipt of an uplink signal for activating the stylus through either one of the first protocol and the second protocol indicated by the setting information, the stylus transmits a downlink signal using the one protocol, and
- in response to receipt of an uplink signal for activating the stylus using the other protocol that is not the one protocol, the stylus does not transmit the downlink signal using the other protocol.
