  • Publication number: 20080051021
    Abstract: Method and sensing module for sensing pollution of outside air. The sensing module (1) comprises an electro chemical sensing element (3), and a processor (2). A sensing module output signal is provided based on the measurement signal and a baseline signal level. The baseline signal level is adapted depending on two threshold levels (13-15). A pollution concentration value is determined from the measurement signal and a classification level of air pollution is provided as sensing module output signal. A classification level is determined using a plurality of classification threshold values and the pollution concentration values. The plurality of classification threshold values are dynamically adjustable.

  • Publication number: 20070205019
    Abstract: A shielding device configured to provide EMI or ESD protection to an electronic component (80) comprises a cover (83), and a wall (10) of a resilient material. By molding the resilient material under the influence of a magnetic field provided by a number of separate magnets, a dispersed plurality of magnetically attractable particles in the material are concentrated in strings (11) extending between a lower (12) and upper (13) end of the wall. The cover is attached to connect to the strings affixed in the solidified wall at the upper end of the wall, and at the lower end of the wall the strings are placed in contact with a ground trace (82) formed around the component to be shielded, thereby forming a Faraday cage about the component.

  • Publication number: 20070194981
    Abstract: A method and system for determining a product level in a tank, comprising determining a first level measure using emission of electromagnetic waves into the tank, detecting a differential pressure, determining an observed density based on the detected differential pressure and the first level measure, and determining a second level measure based on the observed density and a currently measured differential pressure. The present invention is based on the realization that a level measurement based on differential pressure and an observed density can provide a valuable redundant level measurement. Such a redundant measurement can provide increased reliability and enable detection of errors.

  • Patent number: 7243218
    Abstract: The present invention relates to a processing unit for executing instructions in a computer system and to a method in such a processing unit. According to the present invention a decision is made whether or not to base execution on a value prediction (P), wherein the decision is based on information associated with the estimated time gain of execution based on a correct prediction. According to an embodiment of the present invention the decision regarding whether or not to execute speculatively is based on information regarding whether a cache hit or a cache miss is detected in connection with a load instruction. In an alternative embodiment of the present invention the decision is based on information regarding the dependency depth of the load instruction, i.e. the number of instructions that are dependent on the load.

  • Patent number: 6938359
    Abstract: A web-formed material (1), preferably a pulp web (1), is passed through a drying plant, comprising blow boxes arranged in a plurality of drying decks, floating above lower blow boxes, which at their upper sides blow out hot process air against the web-formed material (1). Water, in the form of steam, escaping from the web-formed material (1) is discharged by the process air, at least part of which is recirculated (43) whereas the non-recirculated process air is discharged as exhaust air (41) and is replaced by a corresponding portion of supply air (42) with a low water content. The temperature of the process air is controlled (4).

  • Publication number: 20050060711
    Abstract: The read latency caused by job start preparation of a future job is at least partly hidden within the current job by reading information for job start preparation of the future job integrated with the execution of the current job. Instructions for job start preparation are preferably instrumented (701) into the current job and executed (702), whenever possible, in parallel with the instructions of the current job. The integrated job start preparation may include table look-ups, register file updating, instruction fetching and preparation. If the scheduled job order is allowed to change during execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution, it is typically necessary to test (703) whether the next job is still valid before starting the execution of the next job and take appropriate actions (704; 705, 706) depending on the outcome of the test.

  • Publication number: 20050055490
    Abstract: The present invention relates to mechanisms for handling and detecting collisions between threads (5, 6, 7) that execute computer program instructions out of program order. According to an embodiment of the present invention each of a plurality of threads (5, 6, 7) are associated with a respective data structure (9, 10, 11) comprising a number of bits (12) that correspond to memory elements (m0, m1, m2, mn) of a shared memory (4). When a thread accesses a memory element in the shared memory, it sets a bit in its associated data structure, which bit corresponds to the accessed memory element. This indicates that the memory element has been accessed by the thread. Collision detection may be carried out after the thread has finished executing by means of comparing the data structure of the thread with the data structures of other threads on which the thread may depend.
