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.


A multichat messaging feature enables a user of the device to keep track of and manage multiple chats at once. A quickswitch area includes empty slots that can be filled by the user with avatars corresponding to one to one or group chats. Each avatar is displayed with an indicator showing whether there are new messages within the corresponding chat. The avatars in the quickswitch area may be ordered according to the recency of the messages in the associated conversations. The user has the ability to open a conversation that corresponds to an avatar in the quickswitch area by dragging that avatar from the quickswitch area to either an active conversation area or inactive conversation area. The active conversation area corresponds to a conversation in which the user is actively engaged and has a different visual appearance than the inactive conversation area. The active conversation area, in addition to the text of the active conversation, may include a contact name and avatar for the individual or group participating in the conversation with the user of the device. The inactive conversation area, in addition to selected text of the inactive, but open, conversation, includes an avatar and/or a contact name for the individual or group involved in the inactive conversation.


The invention relates to a current share system (1) comprising parallel DC-DC power converters (2), said power converters each comprising a controller (3) and a power stage (4), connected together such that their V_(out) connections are coupled via interconnect resistances (5) and said controllers are connected via a current share bus (51) as well as to a method for current share bus encoding in the above mentioned current share system. The objective is to provide a current share system allowing parallel power converters to share current on a common output voltage utilizing such a bus, such that it will be possible to communicate additional information between the controllers without reducing the transfer rate of data. This problem is solved by a current share bus which is a digital bus transmitting digital signals, whereas said digital bus employs a data reduction means to transmit current share information at reduced bus clock frequencies and to be capable of communicating additional information between the controllers for the purpose of a fault management and reconfiguration and the like.

The digital signal processing unit calculates a first absolute angle with a period of 180 mechanical degrees provided by the AMR sensor signal and a second absolute angle with a period of 360 mechanical degrees by the Hall sensor signals, whereas intermediate digital signals are generated by the digital processing unit according to the calculated first and second absolute angle signals.

In precision engineering, the degradation of the cutting surface (tool wear) has the greatest affect on accuracy and surface finish of machined parts. Tool wear is the greatest single contributor to scrap (waste material). In the surgical products market, cosmetic finish requirements (16RA) placed on the precision engineered parts continue to be raised to new levels. Similarly, in the aerospace industry parts need to be increasingly accurate in order to increase energy efficiency. Through the development of CNC technology tolerances of 1m are now possible. However, SMEs see significant failures in the current technology. Currently, errors associated with tool wear remain uncompensated for and are usually only detected at the end of the machine cycle, by which time the product is scrap. If such monitoring were available, machining parameters could be adjusted to compensate for tool wear, tools could be replaced earlier, machines could be scheduled for down-time and surface finish and dimensional stability would be increased. Such advances would have a strong impact on the efficiency of processes and increase competitive advantage. The specific aim of the project is to develop a robust smart sensor-based system to provide process a feedback loop to both the CNC machine and the operator.
