Abstract: A device includes an electronic display formed with a stackup of layers and an array of optical sensing elements embedded on at least one layer of the stackup or on a chassis of the electronic display and a circuit connected to the optical sensing elements. The circuit is configured to relate output from the optical sensing elements to pressure applied on the electronic display.

Abstract: A stylus includes a cylindrical shaped housing and a shell. The shell is rotatably connected to the housing. A cross-sectional area of the housing has a first dimension along a first axis and a second dimension along a second axis, the first axis perpendicular to the second axis. The first dimension is smaller than the second dimension. A cross-sectional area including both the shell and the housing has a third dimension along the first axis that is substantially the same as the first dimension while the shell is in a first position and substantially the same as the second dimension while the shell is in a second position.

Abstract: A stylus includes a housing that extends along a longitudinal direction and includes an opening on one end, a tip that extends along the longitudinal direction and through the opening and a sensor configured to detect displacement of the tip in a direction perpendicular to the longitudinal direction.

Abstract: A device includes a connector configured to electrically contact a conductive core of a pencil and a circuit electrically connected to the contact. The circuit transmits a signal via the contact and the conductive core.

Abstract: A stylus placed in a docking station is used as a joystick by setting up a self-capacitance or mutual capacitance between the stylus and the docking port and measuring changes in that mutual capacitance as the stylus is moved by the user. The mutual capacitance is set up using electrodes and/or the housing of the stylus and the changes may be measured either from the stylus or from the docking station.

Abstract: A stylus includes a stylus housing formed with a plurality of slots along a portion of the stylus that is gripped when writing with the stylus, a plurality of tabs located in the housing that can protrude through the plurality of slots and an actuator that actuates protrusion and receding of the plurality of tabs through the plurality of slots. Protrusion of the plurality the tabs through the plurality of slots increases a grip diameter of the stylus housing.

Abstract: A digitizer sensor includes a plurality of antennas defining a grid of junctions and light sensitive material configured to affect capacitive coupling at one or more junctions based on exposure to a beam projected on the digitizer sensor. The plurality of antennas of the digitizer sensor is configured to sense capacitive coupling at the junctions.

Abstract: A sensor includes a sensor layer patterned with conductive elements spread across the sensor layer and a resilient layer proximate to the sensor layer. The conductive elements are electrically isolated from one another. The sensor layer is configured for capacitive based sensing and to detect local compressions based on pressure applied to the resilient layer.
