Patent number: 10698525Abstract: A smart valve positioner is provided with a local user interface with non-mechanical touch buttons and a display inside a positioner housing under a housing cover for locally operating the valve positioner. The touch buttons are user-operable by touching the touch buttons when the housing cover is open. The housing cover is arranged to make the touch buttons user-operable from outside the housing by touching the housing cover, when the housing cover is closed.Type: GrantFiled: May 20, 2016Date of Patent: June 30, 2020Assignee: METSO FLOW CONTROL OYInventors: Tero Ihalainen, Juha Yli-Petäys

Patent number: 10317718Abstract: A smart valve positioner is provided with a local user interface with but-tons and a display inside a positioner housing under a housing cover for locally operating the valve positioner. The valve positioner is further provided with a detector detecting whether the housing or the housing cover is open or closed. The operation mode of the local user interface is configured to be different depending on whether the housing or housing cover is open or closed. For example, a larger variety of operations may be available when the housing or housing cover is open.Type: GrantFiled: May 20, 2016Date of Patent: June 11, 2019Assignee: METSO FLOW CONTROL OYInventors: Tero Ihalainen, Juha Yli-Petäys

Patent number: 7936851Abstract: A method for use in an equalization of a channel by means of an equalizer 22, 23 is shown, wherein the channel uses a certain frequency band for a transfer of signals. In order to enable a channel equalization which requires a low complexity and which provides at the same time a good performance, the method determines a channel response for at least one frequency point within the frequency band used by the channel. The method further sets at least one adjustable coefficient (?0k, bck, brk, a0k, a1k, a2k of the equalizer such that an equalizer response compensates optimally the determined channel response at the at least one selected frequency point. Also shown is a corresponding signal processing device 2, a corresponding signal processing system and a corresponding software program product.Type: GrantFiled: February 20, 2004Date of Patent: May 3, 2011Assignee: Nokia CorporationInventors: Markku Renfors, Tero Ihalainen, Tobias Hidalgo Stitz

Publication number: 20040252772Abstract: The invention relates to a method for a filter bank based signal processing system. In order to enable a signal processing with a low complexity and at the same time a good performance, a method is proposed which comprises in a first step performing a filter-bank based analysis for converting a complex higher-rate channel signal into oversampled lower-rate sub-channel signals, each sub-channel corresponding to a different frequency range. In a second step, the proposed method comprises processing the oversampled lower-rate sub-channel signals with a polynomial model of a system frequency response within the frequency range of the respective sub-channel. The invention relates equally to a unit and a system comprising means for realizing the proposed method.Type: ApplicationFiled: December 31, 2002Publication date: December 16, 2004Inventors: Markku Renfors, Tero Ihalainen, Tobias Hidalgo-Stitz
