Abstract: A stylus for operation with a digitizer device is described. The stylus comprises a housing, at least one transmitter within the housing, electronic circuitry within the housing, the electronic circuitry configured to generate a signal for transmission by the transmitter such that in use, the digitizer device is able to detect the transmitted signal and infer a position of the transmitter with respect to the digitizer device; and an electrically conducting connector. The connector connects the transmitter to the electronic circuitry, and conveys the generated signal from the electronic circuitry to the transmitter. The connector and the transmitter are formed as a single element.

Abstract: In various examples there is a capsule of a stylus for operation with a digitizer device. The capsule is sized and shaped to fit within a housing of the stylus and is a modular capsule which can be used in different styli. The capsule comprises a generally cylindrical housing tapered at a tip end and formed from plastics material. The capsule has a stylus tip comprising a tip antenna. The capsule has at least one antenna printed on an outer surface of the housing.

Abstract: A capacitive sensor for use in a stylus comprises a body of deformable conductive material with a first end and a second end, the first end being configured for fixing to a distal end of a shaft on a longitudinal axis of the stylus and having a stylus tip at a tip end of the shaft. The second end of the body has a face configured to abut a sensing region of a printed circuit board of the stylus when the capacitive sensor is in an active state. A support structure extends from the body of flexible conductive material beyond the second end of the body and is configured to fix to the printed circuit board such that the face of the second end of the body is separated from the sensing region by an air gap when the capacitive sensor is at rest.

Abstract: A pressures sensor for sensing pressure on a tip of a stylus includes a variable capacitor, a power supply, and a capacitance measuring unit. The variable capacitor includes a first electrode coated with solid dielectric layer, a second electrode formed at least in part with elastic material, and a support element that moves together with the tip of the stylus and presses against the second electrode in response to pressure applied on the tip. A portion of the dielectric layer is patterned with a conductive pad that is exposed and the second electrode contacts the conductive pad patterned on the dielectric layer. The power supply and the capacitance measuring unit establish electrical connection with the second electrode via the conductive pad.
