Patent FI-20055650-A (FI)
Inventor: MISIKANGAS PAULI
IPC: H04Q7/38
Filed: 2005-12-07
Abstract: A technique for positioning a target object (TO) in a wireless communication environment. A data model models several sample points (S1-S9). Each sample point comprises a location and a set of expected signal values therein. Signal values are observed (102) at the target object's location. Based on the signal value observations and a set of relevance indicators, a current set (R) of relevant sample points is determined and used, along with the signal value observations, to estimate the target object's location. Computational burden is reduced because sample points (S1-S5;S7) not included in the current set (R) of relevant sample points can be omitted from calculations.

Abstract: 1,232,445. Controlling burners. ROBERSHAW CONTROLS CO. 1 Aug., 1968 [2 Aug., 1967], No. 36852/68. Heading F4T. [Also in Division G3] A main valve 26, 28 controlling the flow of fuel between the inlet 22 and the outlet 24 of a burner control unit is activated by a diaphragm 27 exposed on one side to the inlet pressure and on the other to the pressure in an operating chamber 32 which communicates via a passage 84 with a chamber 81 containing a bleed valve 92 and communicating via unrestricted and restricted bleed lines 82 and 78, 80 with the inlet 22, the bleed valve 92 being operative to either close a bleed passage 86, 88 leading to the outlet 24 and thus close the main valve 26, 28 by equalizing the pressures in the inlet 22 and the operating chamber 32, or to close the unrestricted bleed line 82 and thus allow the operating chamber 32 via the passages 84, 86, 88 to open the main valve 26, 28. The outlet 24 is connected to a main burner 10 ignited by a pilot burner 12 fed with fuel from the inlet 22 via pilot passages 44, 47, 51, 52. The pilot passage 44 is a groove in a rotatable and depressable plug valve 38 which is apertured at 40 to allow the main fuel flow. An inlet valve 72 is mounted on a lever 70 which projects into the path of the plug valve 38 and which is engaged by the armature 67 of a magnetic holding device 66 actuated by a thermocouple 14 sensitive to the pilot burner 12. The bleed valve 92 is spring- urged to close the bleed passage 86, 88, and is engaged by the armature 92 of an electromagnet 90 activated by way of a thermostatic switch 16, the bleed flow being regulated by a regulator 87. In operation, the plug valve is rotated to bring the groove 44 into registry with the inlet 22 whilst taking the aperture 40 out of register. The plug valve is then depressed to open the inlet valve 72 by way of the lever 70, the lever 70 urging the armature 67 against the electromagnet of the holding device 66. Thus fuel flows to the pilot burner 12 where it is ignited to activate the thermocouple and hence the holding device, the inlet valve 72 being held open by a torsion spring 71. The plug valve 38 is rotated to allow fuel to flow to the main valve 26, 28, which, if the thermostat switch is open, opens to allow fuel to the main burner 10. When the thermostat switch closes, the armature 92 of the electromagnet 90 causes the bleed valve to close the unrestricted bleed passage 82 to close the main valve 26, 28. Other embodiments of bleed valve are described with reference to Figs. 4, 5 and 6, 7 (not shown).

In a method of starting-up or closing-down a heat exchanger, e.g. a steam generator comprising an inner wall 10 separating the heating and heated fluids in spaces 13, 15, the pressures of the two fluids are measured by gauges 12, 14, to give a measure of the mechanical stress on the wall 10 and the temperatures on the inner and outer faces 19, 17, are measured by devices 16, 18, to give a measure of the thermal stress on the wall 10. Knowing the designed maximum stress for the wall 10, it can be estimated whether the temperature of the heating fluid should be raised or lowered to avoid axceeding the permissible thermal stress for the existing mechanical stress. The control of the temperature of the heating fluid can be performed manually or automatically and the temperature and pressure differentials may be shown on the same instrument. In a modification the temperature gradient across the wall 10 is measured, rather than the temperature difference of the faces.
