The invention is further related to a corresponding method for pacing the respiration of a person.
Abstract:
A loudspeaker arrangement comprises an acoustic enclosure (101) which is divided into at least two subchambers (103, 105). An audio radiator (109) is mounted in a first subchamber (103) of the at least two subchambers (103, 105) such that it radiates outwardly of the acoustic enclosure (101). A port (107) is included for pneumatically connecting the first subchamber (103) and the second subchamber (105). The system is designed such that a Helmholtz frequency of the first subchamber (103) and the port (107) is at least five times higher than a resonance frequency of the audio radiator (109). The loudspeaker arrangement may provide an improved trade-off between sound pressure levels, audio quality and size and may in particular provide improved low frequency performance without introducing disadvantages typically associated with conventional ported speaker and passive radiator designs.
Abstract:
The invention relates to an interaction system and method for automatically generating a soundscape and lighting, which are adapted to an action of a viewer of displayed items, in order to attract the attention of the viewer to one or more of the displayed items, such as products presented in a shop or displayed in a shopping window. A basic idea of this invention is refining interactivity by triggering the generation of a lighting and soundscape upon detection of a certain viewer or user action and to adapt the generated lighting and soundscape to the viewer or user action. The invention provides in an embodiment an interaction system (10) comprising - at least one detector (12) being adapted to detect an action of at least one viewer (14) showing interest in displayed items (16) and - a controller (18) being adapted to control a light (20) and sound (22) system in response to information received from the at least one detector such that a soundscape and lighting adapted to the detected action is generated.
Abstract:
An apparatus and method for modifying a psychophysiological state of a subject (150) is presented. The method comprises the steps of: detecting a psychophysiologicalmeasure of the subject; processing the detected physiological measure so as to provide a signal indicative of a psychophysiological state of the subject; outputting at least one of an audio stimulus, visual stimulus, haptic stimulus, temperature stimulus and scent stimulus (176, 177) to the subject the output stimulus being derived from an audio- visual data signal provided to the apparatus; and adjusting the output stimulus in real time based on the signal indicative of a psychophysiological state of the subject.
Abstract:
An audio-visual system comprises an optical sensor (OS) for sensing a property of light impinging on an area at or adjacent to a position of a sound transducer (LS) to supply a sense signal (SE) being dependent on the light property, and a controller (1) for receiving the sense signal (SE) to supply an output audio signal (MA) to the sound transducer (LS).
Abstract:
Currently there is no easy way to tell people that they need to take a break and relax, eat or sleep better. A system (100) is described that provides a human low battery warning that indicates to the user in a very simple way that he should change his behavior by sleeping more, eating better or relaxing more to prevent the user from being over-stressed or getting a burnout. This simple warning can help people to take a break when they need it and to make sure that their human battery does not get empty.
Abstract:
A beamforming system (ASY) comprises a modular transducer assembly (MTA) composed of a plurality of transducer modules (TMl, TM2, TM3). A transducer module comprises a plurality of interfaces having different geometrical orientations. An interface allows the transducer module to be physically coupled to another transducer module. In a reconnaissance phase, the beamforming system identifies transducer modules that are present in the modular transducer assembly (MTA). The beamforming system further identifies a structure in accordance with which the transducer modules have been physically coupled to each other. In a configuration phase, the beamforming system defines a signal relationship between the transducer modules on the basis of identification data that has been obtained in the reconnaissance phase and a desired directional response pattern.
Abstract:
The invention relates to a system (10) and method for influencing a photobiological state in a vertebrate (5). The system comprises a light source (30, 32) for emitting light which influences the photobiological state, a sensor (20, 22) arranged to sense a first biophysical parameter (P1), and a control circuit (12) for controlling the light source (30, 32) so as to generate a predetermined photobiological state. The biophysical parameter represents a biological state of the vertebrate (5). The control circuit (12) receives a feedback signal (S1, S2) from the sensor (20, 22) and subsequently sends a control signal (16, 17, 18, S3) to the light source (30, 32) for controlling the light source (30, 32). The control signal is generated by combining a second parameter with the first biophysical parameter. The second parameter is a second biophysical parameter or an interaction parameter characterizing an interaction of the vertebrate with a device. The second parameter represents a further biological state of the vertebrate. The second biophysical parameter is sensed, for example, at a different time and/or is a different biophysical parameter as compared to the first biophysical parameter.
