Abstract: In a pen-based computing system, a pair of microphones captures audio concurrently with a smart pen device capturing handwriting gestures. The audio captured by the pair of microphones is processed to produce an enhanced audio recording. Noise cancellation techniques may be applied to reduce noise generated by the smart pen device interacting with the writing surface to produce a higher quality audio recording. In addition, beam steering techniques may be applied to adjust the gain of portions of the audio signal from different directions and allow the user to focus between multiple audio sources.

Abstract: A pen based computing system concurrently captures handwriting gestures and records audio using binaural recording. A binaural headset communicatively coupled to the smart pen device uses at least two microphones. A left microphone is placed in or near the left ear and the right microphone is placed in or near the right ear, each facing outward. Speakers are integrated into a shared housing with the microphones facing inward towards the ear canal to play back the audio recordings. By recording audio with microphones placed close to the ears, the system provides realistic sounding playback and allows users to more easily differentiate between multiple sources of audio.

Abstract: A portable computer system (e.g., a palmtop or hand-held computer system) with a universal interface module containing circuitry needed to connect with and operate a device such as a display device. The interface module is coupled between the display device and a printed circuit board (e.g., a central processing unit). The interface module can be coupled to the display device using a flexible circuit. In that case, the interface module is pivotable about the flexible circuit so that it can be positioned in different locations within the computer system, depending on space availability and the constraints of a particular computer system design. Thus, the combination of the interface module, the device, and/or the flexible circuit and can be universally implemented in different designs of portable computer systems, reducing development time and manufacturing costs.
