A device to transmit an audio signal comprises at least one light source configured to transmit the audio signal with at least one wavelength of light. At least one detector is configured to detect the audio signal and generate at least one electrical signal in response to the at least one wavelength of light. A transducer is supported with and configured to vibrate at least one of an eardrum, an ossicle or a cochlea. Active circuitry is coupled to the transducer to drive the transducer in response to the at least one electrical signal, so as to provide the user with high quality sound.

A segmented 2D matrix symbol may be formed by dividing data into a plurality of segments, separately encoding the plurality of segments as corresponding arrays of cells, and arranging the arrays of cells in an abutting relationship. The segmented symbol may be reproduced, for example by receiving a bitmap corresponding to the formed symbol followed by printing; by copying a printed symbol; or by scanning a printed symbol and printing a copy. The reproduced symbol may be scanned, and data from only decoded segments, for example audio data, may be output.

An audio signal transmission device includes a first light source and a second light source configured to emit a first wavelength of light and a second wavelength of light, respectively. The first detector and the second detector are configured to receive the first wavelength of light and the second wavelength of light, respectively. A transducer electrically coupled to the detectors is configured to vibrate at least one of an eardrum or ossicle in response to the first wavelength of light and the second wavelength of light. The first detector and second detector can be coupled to the transducer with opposite polarity, such that the transducer is configured to move with a first movement in response to the first wavelength and move with a second movement in response to the second wavelength, in which the second movement opposes the first movement.

An audio signal transmission device includes a first light source and a second light source configured to emit a first wavelength of light and a second wavelength of light, respectively. The first detector and the second detector are configured to receive the first wavelength or light and the second wavelength of light respectively. A transducer electrically coupled to the detectors is configured to vibrate at least one of an eardrum or ossicle in response to the first wavelength of light and the second wavelength of light. The first detector and second detector can be coupled to the transducer with opposite polarity, such that the transducer is configured to move with a first movement in response to the first wavelength and move with a second movement in response to the second wavelength, in which the second movement opposes the first movement.

A position detection system for locating an object including a magnetic field generator is disclosed. The position detection system also includes an array of parallel conductors responsive to a magnetic field generated by the magnetic field generator and a plurality of receivers each associated with a parallel conductor. The parallel conductors are spaced apart from one another by a substantially constant spacing. Each receiver has an associated gain, and the gains of the receivers are configured to simulate voltages induced in conductor loops of sinusoidally-varying pitch.

Position detecting system and method

A system and method for detecting the position of an object are disclosed. A position detection system for locating an object including a resonator comprises an array of parallel conductors responsive to the magnetic field from the resonator, and a plurality of receivers each associated with a parallel conductor. The array of parallel conductors is configured to locate the object along a measurement path. The array of parallel conductors is orthogonal to the measurement path. The system further comprises a plurality of drivers each associated with a parallel conductor and configured to drive current through to produce an energizing field. The array of parallel conductors is provided with sinusoidally varying spacing and driven with sinusoidally varying current. In another embodiment, the array of parallel conductors is provided with constant spacing, and the receivers are configured with gain factors to produce reception similar to reception by sinusoidally spaced conductors. The array of parallel conductors may be driven with three-phase currents to eliminate stationary null points in the energizing field along the lengths of the parallel conductors. A method of detecting position of an object including a resonator comprises providing an array of parallel conductors, providing a plurality of receivers, and associating each of the receivers with a parallel conductor.

Fluid flow can be measured using a multiplicity of sensors in a manner that enables acquisition of detailed information regarding the fluid flow. In particular, the invention can advantageously be used in situations in which the measured fluid flow is anticipated to be turbulent. Even more particularly, the invention can be advantageously be used to obtain measurements of fluid flow in the vicinity of an animate object (e.g., human) which can be used, together with knowledge of the characteristics of the animate object and, if relevant, of one or more objects in the vicinity of the animate object, to determine an intention of, or an effect produced by, the animate object. The invention can be used by people in interacting with a large variety of devices to effect control of those devices.

A personal object or obstacle detector apparatus with enhanced stereo imaging capability includes a sonar system having dual receivers with field lobes positioned based on psychoacoustic considerations such as interaural intensity difference (IID) and interaural time difference (ITD). Receiver field pattern shapes and directions are selected to match the natural IID and ITD associated with human hearing. In one embodiment, dual receivers are used with a common transmitter while another embodiment utilizes two transmitter/receiver pairs with the transmitter and receiver collocated.

A wearable universal user interface device is provided for interacting with a variety of electronic apparatus. The interface device includes various sensors, such as a temperature sensor, pressure sensor, and a two-dimensional quadrant force sensor. The interface device also includes processing circuitry, a wireless transmitter, and an optional receiver. In the preferred embodiment, the interface device is in the form of a ring adapted to be worn on the finger of a user. The device is operated by the wearer's fingers and thumb. Preferably, the interface device includes an internally mounted pressure sensor and an externally mounted two-dimensional force sensor. The body of the ring itself serves as an omnidirectional loop antenna for transmission and reception of signals. Representative applications of the interface device include use as a wireless computer mouse, a remote controller for a television, stereo, VCR, or the like.
