A method of generating an audio signal comprises receiving a plurality of input audio signals from a plurality of microphones forming a microphone array, the plurality of input audio signals being representative of a set of sound sources within the auditory field of view of the microphone array at a given instant in time; receiving a motion input signal from a motion sensor, the motion input signal being representative of the motion of the microphone array; and manipulating the received plurality of input audio signals in response to the received motion input signal to generate an audio output signal that is representative of a set of sound sources within the auditory field of view of a virtual microphone, the apparent motion of the virtual microphone being independent of the motion of the microphone array.

An image viewed by a person is recorded in response to the pointing direction of the eyes of the person by using an optical sensor arrangement that simultaneously derives image segments corresponding with images seen by the person looking forward of his head and to both sides of his head. Alternatively, the sensor arrangement includes plural optical sensors for these images. One image of the plural sensors is selected for recording based on rotation of the head.

A writing implement 1 includes a sensor 11 and control circuitry 13 so that when the writing implement is brought into close proximity with an input screen, the writing tip 3 of the writing implement 1 is prevented from delivering ink to the input screen. This may be achieved in one embodiment by retracting the writing tip within the body of the writing implement, or by extending a stylus tip 20 beyond the writing tip 3. In other embodiments, ink can be prevented from delivered to the input screen by a mechanism which disengages an ink reservoir 5 from the writing tip 3 of the writing implement 1 and/or, in the case of a ball-point pen type writing tip 3, electromagnets 26 can be arranged to prevent rotation of an ink delivery ball 22.

A printer 802 is adapted to produce a printed image with an associated sound passage stored on an electronic storage device. The printer 802 comprises an information input for receiving information to define a visual image and also information defining a passage of sound. The printer has a printer element 808 for printing the first information as a printed image 804, but also has a writing element 807 for writing the sound information into an electronic storage device 803 adapted for attachment to the printed image. An appropriate mechanism 805 for attaching the electronic storage device to the printer image is provided at the printer.

A digital pen of the kind having means to sense and create a digital record of the use made of the pen and a memory in which the digitised record is stored also includes a reader for communication with memory tags by inductive coupling. The means to sense and create a digital record of the use made of the pen may include a camera. Preferably the reader for communication with memory tags is located at the opposite end of the pen from a nib for convention writing, and the pen includes a battery power supply.

An image capture device electronically captures and selects a desired text portion. A visible light image is projected onto text on a document to enable a user to position the light image relative to the desired text portion. At least some of the text is captured in accordance with a position of the light image. A text selector selects the desired text portion from the captured text.
摘要:
A method for generating individual glyphs, and a system and method for inspecting individual glyphs are disclosed. The system includes a true resolution imaging device configured to capture an image of a printed glyph. A registry service has a database for storing other glyphs and/or parameters of other glyphs. An analysis system, in selective communication with the registry service, includes computer software configured to receive the captured image; an image analysis program configured to perform forensic analysis on the received image to determine parameter(s) associated with the glyph; and an image comparison program configured to i) compare the glyph parameter(s) with parameters stored in the registry for other glyphs or with parameters determined, by image analysis program, for the other glyphs stored in the registry, and ii) generate a probability that the glyph and object are authentic based upon the comparison.
摘要:
A passage of sound is attached to a printed image 11 by means of an electronic storage medium 12. The electronic storage medium 12 comprises a die 16 containing a non-volatile memory and a flexible substrate 14 with connectors 15. The connectors can be interfaces with a separate reader 4 which plays the passage of sound recorded in the electronic storage medium. Further information is also provided in the electronic storage medium 12 memory. This further information relates to the printed image. Such information may include a version of the image printed, either to the same or to a lower resolution. It may also include information relating to image capture conditions or location, or information allowing referencing or indexing of the image.
