Abstract:
The present invention describes a method and an apparatus for preventing damage to an apparatus resulting from the consequences of a free fall. In this case, first of all, a free fall of the apparatus is identified and a measure is then carried out to protect the apparatus against damage. According to the invention, free fall is in this case identified by detecting the ambient pressure. The apparatus may have a hard disk in which the write/read head of the hard disk is parked and/or locked on identifying the free fall.
Abstract:
The invention relates to a sensor having a detection element, an analogue frontend and a digital backend; wherein the digital backend is to be connected to a control unit via a digital interface, wherein the sensor provides sampled data in the digital backend. The sensor contains means for providing time information relating to the sampled data in the digital backend, which information can be accessed by the control unit by means of the digital interface. The invention also relates to a method for assigning an item of time information to sampled measurement data from a sensor.

Abstract:
Die Erfindung beschreibt ein Herstellungsverfahrens eines insbesondere mikromechanischen Halbleiterbauelements sowie ein mit diesem Verfahren hergestelltes Halbleiterbauelement. Zur Herstellung des Halbleiterbauelements ist vorgesehen, dass auf einem Halbleiterträger ein strukturiertes Stabilisierungselement mit wenigstens einer Öffnung erzeugt wird. Die Öffnung ist dabei so angebracht, dass sie den Zugang zu einem mit einer ersten Dotierung aufweisenden ersten Bereich im Halbleiterträger erlaubt. Weiterhin ist ein selektives Herauslösen wenigstens eines Teils des mit der ersten Dotierung versehenen Halbleitermaterials aus dem ersten Bereich des Halbleiterträger vorgesehen. Darüber hinaus wird mittels einer ersten Epitaxieschicht, die auf das Stabilisierungselement aufgebracht wird, eine Membran oberhalb des ersten Bereichs erzeugt. Wenigstens ein Teil des ersten Bereichs dient in einem weiteren Verfahrensschritt dazu, eine Kaverne unterhalb des Stabilisierungselement zu erzeugen. Der Kern der Erfindung besteht nun darin, das strukturierte Stabilisierungselement mittels einer zweiten Epitaxieschicht, die auf dem Halbleiterträger aufgebracht wird, zu erzeugen.

The invention also relates to a sensor system with at least one sensor according to the invention and an external control unit, by means of which at least the first register can be read and at least the second register can be written. The invention also relates to a combination sensor system comprising at least one sensor system according to the invention with at least two sensors according to the invention. The invention also relates to a method for adjusting the phase position and/or the periods of data samples in a sensor system according to the invention or a combination sensor system according to the invention.
Abstract:
The invention relates to a method for determining positions, having a first step (10), wherein a first sequence (12) of positions is determined from radio signals of essentially positionally fixed transmitters and wherein a second sequence (14) of positions is determined from other sensor data by compound navigation. The core of the invention consists in the fact that the first sequence of positions (12) and the second sequence of positions (14) are compared with one another in a second step (20). The invention also relates to a computer program product for carrying out the method. The invention also relates to a position-determining device (100), in particular in a mobile terminal, having a receiver (110) for the radio signals of positionally fixed transmitters, having position-determining means (160) for determining a first position of the receiver from radio signals of positionally fixed transmitters, having sensors (120) at least for determining a direction and a distance in order to determine a second position by compound navigation, and having a memory (130) for storing a sequence of first positions and a sequence for second positions. The core of the invention consists in the fact that the position-determining device has a processing device (140) for comparing the sequence of first positions and the sequence of second positions.
