Abstract: Customer devices (e.g., mobile cellular phones) are configured to interact with a communications service provider (and optionally an administration and monitoring system). A customer device is configured as a “capped pay-as-you-go” device in which the customer associated with the device is charged no more than a pre-arranged amount in any given (dynamic or static) billing period. For example, if $50 is the “capped” amount for a billing period, a user might pay $10 for using 1 gigabyte of data in a billing period, or it might pay $50 whether it used 5 gigabytes of data or 10 gigabytes of data in a single billing period.

Abstract: In a device for determining absolute position of a mobile element in reference to two magneto-sensitive sensors, having a source of a magnetic field fastened to the element, a first sensor signal and a second sensor signal are measured with one magneto-sensitive sensor each. An amplitude ratio of the respective sensor signals and the off-set values about the respective zero point of the sensor signals are determined from the minimum and maximum values of the sensor signals, and from these values, scaled sensor signals are calculated that form a sum signal and a difference signal, which are scaled, with the determination of the minimum and the maximum values occurring by a relative movement of the element over a full range of motion, and an absolute position is calculated via the scaled sum signal and the scaled difference signal.

Abstract: The invention relates to a UV light sensor produced in a CMOS method, comprising a substrate that has a surface, one or more sensor elements that detect radiation and are designed in said substrate, at least one passivation layer arranged over said substrate surface, and a functional layer that is arranged over said passivation layer and designed in the form of at least one filter. The problem addressed by the invention of providing a UV light sensor which is sensitive exclusively within the UV wavelength range is solved, in terms of arrangement, by means of filters designed directly on a planar passivation layer, and stray light suppressing means around said at least one sensor element and/or around the UV light sensor. In terms of the method, the problem is solved by measuring two output signal from at least two photo diodes fitted with different filters, and by determining a mathematical relationship between the two output signals.

Abstract: An optical lens has a light sensing die integrated into the optical lens. The optical lens is extended compared to a spherical optical lens such that the optical lens is elongated in order to allow for placement of the ambient light sensing die without causing any blocking or distortion of the optical lens. The shape of the optical lens and the placement of the ambient light sensing die is compensated for the change in shape compared to a spherical optical lens thus allowing for correct focal length parametrics.

Abstract: A switched power converter includes a power stage for generating an output voltage according to a switching signal and an input voltage via a switching element. The switching signal is generated by a variable timing generator which is controlled by a compensator. The pulses of the switching signal are generated on a “need to have basis”. Hence, theses pulses may be generated independently of a PWM period. The pulses can be generated such that switching losses are minimized. A switching pattern can be matched to the load current pattern. Thus, the behavior of the compensator can be synchronized to a regular pattern of the load current. A high resolution variable timing generator may be employed.
