ACTIVE STYLUS TO HOST DATA TRANSMITTING METHOD
First Claim
Patent Images
1. A method, comprising:
- receiving, at a stylus, an indication that a host device is performing a first coordinate scan to determine coordinates of the stylus proximate to a capacitive sense array of the host device; and
while the host device is performing the first coordinate scan, transmitting at least two bits of stylus data to the host device.

Abstract
Apparatuses and methods of active stylus to host device data transmitting. One method receives, at a stylus, an indication that a host device is performing a first coordinate scan to determine coordinates of the stylus proximate to a capacitive sense array of the host device. While the host device is performing the first coordinate scan, the stylus transmits at least two bits of stylus data to the host device.

11. A system, comprising
a stylus comprising: -
a tip driver; a receiver configured to receive indications of coordinate scans performed by a host device to determine coordinates of the stylus proximate to a capacitive sense array of the host device; and a processing device coupled to the receiver and the tip driver, wherein the processing device is configured to transmit at least two bits of stylus data per each of the coordinate scans performed by the host device. - View Dependent Claims (12, 13, 14, 15, 16, 17, 18)

19. A stylus, comprising:
-
a force sensor; and a processing device coupled to the force sensor, and wherein the processing device is configured to implement a stylus data state machine, wherein the stylus data state machine comprises a first state in which the force sensor is not pressed, a second state in which the force sensor is pressed, a third state in which the force sensor is still pressed, and a fourth state in which the force sensor is released. - View Dependent Claims (20)
