| 20090118565 | METHOD IN CONNECTION WITH STEEL PRODUCTION - The invention relates to a method in connection with steel production for handling of hydroxide sludge formed in the neutralization of spent metal-contaminated pickling agents from a pickling step for steel, preferably stainless steel and for using calcium fluoride in the hydroxide sludge to replace the natural fluorspar as a fluxing agent in connection with steel production. Accordingly, the addition of the reactive neutralization medium is monitored by the pH electrodes operated in continuous fashion, and the pH value is adjusted at the range between 9.0 and 9.5. | 05-07-2009 |
| 20100275728 | METHOD IN CONNECTION WITH STEEL PRODUCTION - A method of producing a fluxing agent that can be used in production of steel, preferably stainless steel, employs as a raw material a hydroxide sludge that results from neutralization of metal-contaminated pickling liquid from a pickling step for a steel and contains at least one fluoride-containing compound. The hydroxide sludge is calcined. Steel, preferably stainless steel, is produced by decarburizing a steel heat, whereby a slag is formed on top of the steel heat, and adding a fluxing agent to the slag. | 11-04-2010 |

| 20100196861 | METHOD OF OPERATING A HEARING INSTRUMENT BASED ON AN ESTIMATION OF PRESENT COGNITIVE LOAD OF A USER AND A HEARING AID SYSTEM - A method of operating a hearing instrument for processing an input sound and to provide an output stimulus according to a user's particular needs, and related system, computer readable medium and data processing system. An object is to provide an improved customization of a hearing instrument. The method includes the steps a) providing an estimate of the present cognitive load of the user; b) providing processing of an input signal originating from the input sound according to a user's particular needs; and c) adapting the processing in dependence of the estimate the present cognitive load of the user. The estimate of the present cognitive load of a user is produced by in-situ direct measures of cognitive load (e.g. based on EEG-measurements, body temperature, etc.) or by an on-line cognitive model in the hearing aid system whose parameters have been preferably adjusted to fit to the individual user. | 08-05-2010 |

| 20100141439 | TIME FOR EAR PILL INTAKE DETERMINED BY NOISE DOSIMETRY IN WEARABLE DEVICES - The disclosure relates to a portable processing system adapted for being worn by a user and comprising an input transducer for converting an input sound to an electric input signal, and a signal processing unit adapted for processing an SPU-input signal originating from the electric input signal. The disclosure further relates to use of such system and to a method. The object of the present disclosure is to provide an alerting device aiding a user in administering the dose of a hearing protecting agent. The problem is solved in that the signal processing unit comprises a monitoring part for monitoring and determining an accumulated sound dose AccD in the electric input signal from a start time t0 and for generating an alarm output at a threshold time t | 06-10-2010 |
