Abstract: An electronic device has a sensor panel and a display upon which content is rendered in use. A control module controlling the sensor panel enters a whiteboard-style erase mode when specified conditions are met. The control module is configured to, in the whiteboard-style erase mode detect a first position on the sensor panel of a first point on a stylus; detect a second position on the sensor panel of a second point on the stylus, the second point being spaced from the first point; compute the location of the longitudinal axis of the stylus on the sensor panel from at least the detected first and second positions; and trigger an update of the rendered content at a location on the display related to the location of the longitudinal axis of the stylus on the sensor panel.

Abstract: A stylus includes a housing extending over a length and including a first end opposite a second end, a circuit configured to generate a signal, a power source configured to power generation of the signal, a writing tip extending from the first end of the housing, and a light harvesting unit configured to generate energy. The light harvesting unit includes a transparent window integral with the housing and positioned proximal to the writing tip, a panel of solar cells configured to absorb light received through the transparent window, optical fibers configured to transmit light from the window toward the panel of solar cells and an optical diffuser configured to diffuse the light transmitted by the optical fibers over a spatial extent of the panel of solar cells. The energy generated by the light harvesting unit is received by the circuit and configured to recharge the power source.

Abstract: Multi-transmitter stylus tip techniques are described herein. In implementations, a stylus employs a tip having an array of transmitters designed to can convey information regarding the shape, size, and position of the tip in three-dimensional space. The array of transmitters may be arranged in groups or layers disposed at different levels in relation to a three-dimensional volume of the tip. In implementations, the tip is configured as a brush head having a plurality of flexible bristles. In this approach, the array of transmitters may be spread across the bristles to represent or “map” the shape of the brush. A tip may be implemented as an integrated tip that is fixed to a stylus or as an interchangeable tip that is removably coupled to a stylus via an interface and interchangeable with a set of different tips supported by the stylus.

Abstract: A circuitry for a computing system comprising a first load/store unit, LSU, and a second LSU as well as a memory arrangement. The first LSU is connected to the memory arrangement via a first bus arrangement comprising a first write bus and a first read bus. The second LSU is connected to the memory arrangement via a second bus arrangement comprising a second write bus and a second read bus. The computing system is arranged to carry out a multiple load instruction to read data via the first read bus and the second read bus and/or to carry out a multiple store instruction to write data via the first write bus and the second write bus.
