摘要:
The present invention relates to a luminaire comprising an array of LEDs emitting light of at least one colour, and a control system for controlling the light output of the luminaire. The control system comprises photosensor array for detecting light output of the luminaire. An imaging unit is arranged in front of the photosensor array such that it maps an image of said array of LEDs on said photosensor array. The photosensor array is divided into subareas each detecting light output from a single one of the LEDs. The control system uses the output of the subareas for controlling the luminaire light output. Thus, it is possible to act on different LED light colours or the light output of individual LEDs without having to separate them in time by means of a time pulsing method.

The present invention relates to a method of controlling the output of a luminaire comprising an array of LEDs emitting light of at least one color. The array has single color LED groups, wherein each group consists of at least one LED. The method comprises the following steps for each LED group:spectrally filtering the light emitted by the LED group by means of a first filter as well as by means of a second filter; detecting the spectrally filtered light from said first and said second filter and generating respective first and second response signals, wherein the levels of said first and second response signals are related to the respective amounts of detected spectrally filtered light; and controlling the light output of said LED group on the basis of said first and second response signals, wherein the filter characteristics of said first and said second filter are at least partly non-overlapping. The invention also relates to a corresponding control system for performing the method.

The present invention relates to an integrated electronic-microfluidic device an integrated electronic-microfluidic device, comprising a semiconductor substrate (106) on a first (122) support, an electronic circuit (102, 104) on a first semiconductor-substrate side of the semiconductor substrate, and a signal interface structure to an external device. The signal interface structure is arranged on the first semiconductor-substrate side and configured to receive electrical signals from the electronic circuit. A microfluidic structure (126) is formed in the semiconductor substrate, and is configured to confine a fluid and to allow a flow of the fluid to and from the microfluidic structure only on a second semiconductor-substrate side that is opposite to the first semiconductor-substrate side and faces away form the first support. The electronic-microfluidic device forms a flexible platform for the formation of various System-in-Package applications. It achieves a clear separation between electrical and wet-chemical interfaces. The claimed method for fabricating the device of the invention also allows a simple formation of thermally isolated microfluidic structures.

An elongate device (e.g. a catheter) for interventional MRI has one or more passive LC-circuits (wireless markers) attached to its distal tip portion for position tracking. The LC-circuits comprise an inductor winding (480) and a three-dimensional “trench” capacitor (420-440) and are integrated in a piece of silicon (410). Optical fibres may be included in the device for optical probing of tissue surrounding the distal tip portion.

摘要:
An integrated-circuit device includes a rigid substrate island having a main substrate surface with a circuit region circuit elements and at least one fold structure. The fold structure is attached to the substrate island and is unfoldable from a relaxed, folded state to a strained unfolded state. The fold structure contains at least one passive electrical component. The fold structure further has in its folded state at least one surface with an area vector that includes a non-vanishing area-vector component in a direction parallel to the main substrate surface, which area-vector component is diminished or vanishes when deforming the fold structure from the folded into the unfolded state.
