摘要:
A device for positioning a transducing head (14) over a selected track of a rotatable information disc. The device includes a slider (12) supporting the transducing head, a carrier supporting the slider, a drive for moving the carrier to effect coarse radial positioning of the transducing head with respect to said selected track and a microactuator (18) to effect fine radial positioning (F) of the transducing head with respect to said selected track. The slider is provided with a swinging element carrying the transducing head and the microactuator is arranged to move the swinging element. In order to obtain a compact device with a swinging element of small mass, the swinging element is an internal tongue-shaped portion (12b) of the slider, the transducing head being secured to a free end part (12ba) of said tongue-shaped portion. The tongue-shaped portion extends in a recess (16) of the slider in which recess the tongue-shaped portion is swingable and in which recess the microactuator is provided.

The invention relates to a system (102) for providing biofeedback to a person (104). The system (102) comprises a source (106) for generating a source signal (108) and a transducer (110) for generating a measurement signal (112) in response to a physiological parameter (114) indicative for mental relaxation of the person (104). The system (102) furthermore comprises a filter (116) for variably filtering the source signal via modifying a cut-off frequency in response to the measurement signal (112) and an interface (118) for providing a biofeedback signal (119) to the person on the basis of the source signal as variably filtered by the filter (116).

The invention relates to a method and a system for reducing anxiety of patients before and during e.g. MR scanning examinations. The method is based on displaying images on walls (106,107) of the scanner room (100) so that when the patient enters the scanner room, then an image is displayed on a wall visible to the patient, e.g. a wall adjacent to the entry door (103). When the patient is laying on the table (102) of the scanner (101) the projection of images is switched to another wall by reflecting the projected images using e.g. a mirror which is moved into the light rays emitted by an image projector.

The invention relates to a control system (100) for an ambient light environment in a room in a hospital environment. The control system is configured to time and synchronize light effects of the ambient light environment (170, 190) in response to sensor signals (111-113) from patient location sensors (121) or other sensors (122,123) for detecting if a clinical instrument is activated, moved or taken into use or for detecting heart rate. Light effects may be used by the clinical personnel to improve quality and speed of the examination and to create a calming atmosphere for the patient. However, different light effects are required at different times and for different durations. Therefore, timing of the light effects relative to sensor signals may improve workflow and patient comfort.

The Invention concerns to a micro-actuator device for the use in biochip or bio-system. In order to achieve a micro-actuator device for the use as a micro pump in biosensors or bio-systems, or at least bio-chips, by which the actuation can be steered very precisely and effective, the solution is that the micro actuator consist of a photosensitive actuator element (1), which can be deformed from a reversal basic-form into an activated deformation form by photonic activation of a light source (3, 4, L1, L2) in order to generate with this controlled movement a defined flow in a gas or a liquid.
摘要:
A storage medium for storing digital information is disclosed. The storage medium comprises a label comprising a light addressable electrophoretic ink layer. Further, a method for labeling a storage medium provided with an electrophoretic ink label is disclosed. The method comprises the steps of applying a voltage between a first and a second electrode being arranged on mutual sides of a electrophoretic ink layer; irradiating selected pixel areas of the electrophoretic ink for addressing a change of visual state. Further, a recorder for an optical storage medium and a label writer for labeling an optical storage medium are disclosed. The recorder and the label writer comprise a light source and a charging device. The charging device is arranged to apply an electric field across an electrophoretic ink layer of the storage medium, and the light source is arranged to write a label on said storage medium by addressing pixel areas of said electrophoretic ink layer.
