In one embodiment, a stylus includes one or more electrodes and one or more computer-readable non-transitory storage media embodying first logic for transmitting signals wirelessly to a device through a touch-sensor of the device. The stylus has a first power mode in which components of the stylus for receiving signals from or transmitting signals to the device are powered off; a second power mode in which components of the stylus for receiving signals from the device are powered on at least periodically and components of the stylus for transmitting signals to the device are powered off; and a third power mode in which components of the stylus for transmitting signals to the device are powered on at least periodically. The media further embodies second logic for transitioning the stylus from one of the first, second, and third power modes to another one of the first, second, and third power modes.

Power management system for active stylus

In one embodiment, a stylus comprising an accelerometer operable to detect an acceleration in response to a touch to the body and initiate a pre-determined function, a method of using same, and one or more non-transitory computer-readable storage media embodying logic.

Executing gestures with active stylus

In one embodiment, a stylus receives a first signal from a first electrode of the stylus, the stylus being operable to communicate wirelessly with a device through a touch sensor of the device; receives a second signal from a second electrode of the stylus, the second signal being a reference signal and the second electrode being a reference electrode; and compares the first signal with the second signal.

Differential sensing in an active stylus

In one embodiment, a device includes a stylus tip capable of communicating wirelessly with another device through a touch sensor of the other device. The stylus tip includes one or more surface areas, one or more substrates disposed along one or more of the surface areas of the stylus tip, and a plurality of electrodes disposed on or in the one or more substrates.

Multi-electrode active stylus tip

In one embodiment, a stylus with one or more electrodes and one or more computer-readable non-transitory storage media embodying logic for transmitting signals wirelessly to a device through a touch sensor of the device has one or more sensors for detecting movement of the stylus.

A stylus includes a pen-tip; a sensor; and a processor operable to: operate in a lower-power mode and a higher-power mode; detect, with the sensor, a defined frequency or a defined range of frequencies indicating shaking of the stylus; and transition from the lower-power mode to the higher-power mode in response to the detection of the defined frequency or the defined range of frequencies. The processor is prevented from transitioning from the lower-power mode to the higher-power mode in response to detection of a frequency other than the defined frequency and a range of frequencies other than the defined range of frequencies. The processor, in response to a relative motion between the stylus and a device in communication with the stylus, process both a device signal representative of the relative motion and a stylus signal representative of the detection of the defined frequency or the defined range of frequencies.

Touch-sensitive system with motion filtering

A pre-fabricated sensor assembly for an interactive object including an object substrate is provided. The pre-fabricated sensor assembly includes a touch sensor comprising a plurality of flexible sensing elements, a first electronics module comprising sensing circuitry in electrical communication with the plurality of flexible sensing elements, a communication interface comprising a first end portion coupled to the first electronics module and comprising a second end portion, a receptacle coupled to the second end portion of the communication interface, and one or more flexible retaining layers that define a housing for a first portion of the pre-fabricated sensor assembly. The first portion of the pre-fabricated sensor assembly can include at least a portion of each of the plurality of flexible sensing elements.

Pre-fabricated sensor assembly for interactive objects

A removable electronics device and related pre-fabricated sensor assemblies having different sensor layouts are provided. The removable electronics module includes one or more processors, an inertial measurement unit, a first communication interface configured to communicatively couple the removable electronics device to one or more computing devices, a second communication interface configured to communicatively couple the removable electronics device to a plurality of pre-fabricated sensor assemblies, and a housing at least partially enclosing the processor, the inertial measurement unit, the first communication interface, and the second communication interface. The housing includes a first opening in at least one longitudinal surface and adjacent to at least a portion of the first communication interface and a plurality of second openings in a lower surface and adjacent to the plurality of contact pads of the second communication interface.

Removable electronics device for pre-fabricated sensor assemblies

In one embodiment, an active stylus includes a receiver and a transmitter configured to receive and transmit signals from and to a device via a touch sensor of the device, wherein the transmitter is integrated with or comprises an adaptive voltage generation circuit including: a boost voltage controller; a comparator; a switch control; and a bleeder circuit. The active stylus further includes a stylus controller configured to: (a) in a first operation state, control the adaptive voltage generation circuit and the transmitter to transmit signals at a second transmit voltage, and (b) in a second operation state different from the first operation state, control the adaptive voltage generation circuit and the transmitter to transmit signals at a first transmit voltage lower than the second transmit voltage.
