Abstract: An active stylus includes a stylus tip assembly and an elongate housing enclosing a portion of the stylus tip assembly. A winged bracket mounted within the elongate housing and affixed to a tip-distal end of the stylus tip assembly is configured to flex in response to pressure applied to the stylus tip assembly. A strain gauge disposed along the winged bracket is configured to measure strain along the winged bracket caused by pressure applied to the tip assembly.

Abstract: An active stylus includes an elongate housing having a tip end and a secondary end, opposite the tip end. An inductive charging coil is mounted within the elongate housing, between the tip end and the secondary end. A magnet configured to magnetically hold the inductive charging coil in a charging position and orientation relative to an inductive charger is moveably mounted within the elongate housing between the tip end and the inductive charging coil.

Abstract: An electronic stylus device includes a stylus tip element having a stylus tip end and an opposing end. The stylus tip element is positioned at an end of the electronic stylus device and aligned along the long center axis of the electronic stylus device. A nutation collar is positioned about the stylus tip element and the long center axis. The nutation collar provides one or more bearing surfaces around the stylus tip element between the stylus tip end and the opposing end of the stylus tip element. The one or more bearing surfaces permit the stylus tip element to nutate within the nutation collar. A deflection sensor is positioned proximate to the opposing end of the stylus tip element on the long center axis and detects lateral deflection of the opposing end of the stylus tip element relative to the long center axis of the electronic stylus device.

Abstract: An electronic device has a chassis with an open state and a closed state. The chassis has a first portion, a second portion, and a perforated hinge. The first portion has a first outer edge and a first inner edge. The second portion has a second outer edge and a second inner edge. The perforated hinge has a plurality of perforations. The perforated hinge is positioned between the first portion and the second portion at the first inner edge and the second inner edge. The first portion, the second portion, and the perforated hinge are integrally formed from a continuous piece and the perforated hinge is deformable to mate the first outer edge to the second outer edge in the closed state.

Abstract: The structure and devices described herein provide an improved attachment for a peripheral device, such as a stylus, to a computing device when not in use. A stylus may have magnets contained therein that cooperate with magnets in a computing device to magnetically secure the stylus to the computing device when not in use. In addition, a retractable interlock may automatically extend from the stylus when the stylus is in proximity of the computing device. The interlock is received in a receptacle of the computing device to provide an improved attachment through the mechanical interaction of the interlock and the receptacle. The interlock is biased in a retracted position and automatically extends through magnetic attraction with the computing device.

Abstract: The described technology includes a digital pen tip with a pen tip body and an elastomeric front end formed at a front end of the pen tip body, wherein the pen tip body is formed during a first stage of a two shot molding process and the front end is formed at a second stage of the two shot molding process.

Abstract: In implementations of a linear encoder force transducer, an encoder component generates light that enters a light input window of an encoder strip, and reflective surfaces disperse the light internally within the encoder strip. The encoder strip has etched lines formed cross-width of the encoder strip for emitted light that exits the encoder strip. The encoder component has gradated slots through which the emitted light from the encoder strip is detected by an array of photo transistors, each of the gradated slots corresponding to one of the photo transistors in the array of photo transistors. An encoder module can determine a linear displacement, such as representative of a force applied to a pen tip of a computer input pen, based on one or more of the photo transistors detecting the emitted light as the etched lines of the encoder strip move relative to the gradated slots of the encoder component.

Abstract: The described technology includes a fluid force sensor interface between a pressure sensor, such as a barometric pressure sensor disposed inside a sensor housing with an aperture, and a container with an interior cavity exposed to the ambient environmental fluid pressure. The interior cavity of the container may equalize with the pressure of the ambient fluid environment, and may cooperate with the aperture on the sensor housing to create at least a partial fluid seal. A force member may transmit an applied outside force to deform the container, and the interior cavity therein, to reduce the volume of the interior cavity and thus increase pressure inside the interior cavity. The fluid force sensor may measure the applied force by sensing an increase in pressure inside the interior cavity. After the outside applied force has been removed, the pressure inside the interior cavity may equalize with the ambient fluid pressure.
