Non-volatile memory

Sensors () for sensing accelerations are provided with accelerometers () for measuring accelerations, with magnetometers () for measuring magnetic fields, and with processors () for, in response to acceleration measurements and magnetic field measurements, judging the accelerations. The processors () may comprise acceleration units () for comparing acceleration signals with acceleration thresholds, and magnetic field units () for comparing changes of magnetic field signals per time interval with rate thresholds. The processors () may further comprise decision units () for, in response to comparison results from the acceleration units () and the magnetic field units (), deciding whether a total acceleration forms part of a tumbling free-fall or a non-tumbling free-fall or not. The processors () may yet further comprise distinguishing units () and control units (). Devices () may comprise sensors ().

A non-volatile memory is disclosed. A contiguous layer of phase change material is provided. Proximate the contiguous layer of phase change material is provided a first pair of contacts for providing an electrical current therebetween, the electrical current for passing through the contiguous layer of phase change material for inducing heating thereof within a first region. Also adjacent the contiguous layer is provided a second pair of contacts disposed for providing an electrical current therebetween, the electrical current for passing through the contiguous layer of phase change material for inducing heating thereof within a second region thereof, the second region different from the first region.

Programmable phase-change memory and method therefor

A non-volatile memory is disclosed. A contiguous layer of phase change material () is provided. Proximate the contiguous layer of phase change material () is provided a first pair of contacts () for providing an electrical current therebetween, the electrical current for passing through the contiguous layer of phase change material () for inducing heating thereof within a first region. Also adjacent the contiguous layer is provided a second pair of contacts () disposed for providing an electrical current therebetween, the electrical current for passing through the contiguous layer of phase change material () for inducing heating thereof within a second region thereof, the second region different from the first region. This pairs of contacts may be disposed on the same side or on opposing sides of the phase change material layer.

Magnetic field sensors () comprising field detectors () for detecting magnetic fields are provided with environment detectors () for detecting environments and with processors () for, in response to detected environments, performing processes such as loading calibration parameter sets and (re)calibrations for the field detectors (), to allow the magnetic field sensors () to be used in different subsequent environments.

Magnetic field sensor

Systems comprising generating devices comprising sensors for generating sensor signals representing orientations of the generating devices are provided with comparing devices comprising comparators for comparing the sensor signals with reference signals for interpreting the orientations, to increase the number of possible applications. The generating devices and the comparing devices may form parts of one apparatus or of different apparatuses and then communicate wiredly or wirelessly via radio or infrared. Reference sensors for generating the reference signals and/or reference memories for storing the reference signals may be located in the comparing devices and/or in sources and then communicate wiredly or wirelessly via radio or infrared. Further comparators in the comparing devices may introduce adjustable sensitivities.
