  • Publication number: 20250055396
    Abstract: A motor controller executes an axis module for each of multiple motors coupled to a shared load. A first control module passes at least one state variable to a second control module without experiencing communication delays between the axis modules. In order to decouple interaction between axes, the first control module determines the desired state variable at a periodic update rate and stores the desired state variable in memory. The first control module provides an indication to the second control module that the desired state variable is available. Within the same period at which the desired state variable is determined, the second control module receives the indication that the desired state variable is available and reads the state variable from the memory of the controller. The second control module executes using the desired state variable to reduce coupling between the two control modules.

  • Publication number: 20250022475
    Abstract: A method for encoding an input audio stream including the steps of obtaining a first playback stream presentation of the input audio stream intended for reproduction on a first audio reproduction system, obtaining a second playback stream presentation of the input audio stream intended for reproduction on a second audio reproduction system, determining a set of transform parameters suitable for transforming an intermediate playback stream presentation to an approximation of the second playback stream presentation, wherein the transform parameters are determined by minimization of a measure of a difference between the approximation of the second playback stream presentation and the second playback stream presentation, and encoding the first playback stream presentation and the set of transform parameters for transmission to a decoder.

  • Publication number: 20220018179
    Abstract: Certain example embodiments relate to electric, potentially-driven shades usable with insulating glass (IG) units, IG units including such shades, and/or associated methods. In such a unit, a dynamic shade is located between the substrates defining the IG unit, and is movable between retracted and extended positions. The dynamic shade includes on-glass layers including a transparent conductor and an insulator or dielectric film, as well as a shutter. The shutter includes a resilient polymer-based layer and layers on opposing surfaces thereof. A first voltage is applied to the transparent conductors to cause the shutter to extend to a closed position.

  • Publication number: 20220018178
    Abstract: Certain example embodiments relate to an insulating glass (IG) unit. A spacer system is interposed between first and second substrates. The spacer system helps to maintain the first and second substrates in substantially parallel spaced apart relation to one another, and to define a cavity between the first and second substrates. A desiccant material is located in a body of the spacer system, with the desiccant material comprising a desiccant matrix and a molecular sieve replacement material formed for adsorption at a relative humidity of 10-20%. The molecular sieve replacement material may be a salt or other material (such as, for example, MgCl2, CaCl2, CaO, MgSO4, and/or the like). The cavity may be primarily filled with an inert gas (such as Ar, Kr, Xe, or the like) or a reactive gas (such as CO2). An electrostatically-driven dynamic shade may be provided in the cavity.

  • Patent number: 10717668
    Abstract: Certain example embodiments of this invention relate to edge sealing techniques for vacuum insulating glass (VIG) units. More particularly, certain example embodiments relate to techniques for providing localized heating to edge seals of units, and/or unitized ovens for accomplishing the same. In certain example embodiments, a unit is pre-heated to one or more intermediate temperatures, localized heating via at least one substantially two-dimensional array of heat sources is provided proximate to the peripheral edges of the unit so as to melt frits placed thereon, and cooled. In certain non-limiting implementations, the pre-heating and/or cooling may be provided in one or more steps. An oven for accomplishing the same may include multiple zones for performing the above-noted steps, each zone optionally including one or more chambers.

  • Publication number: 20190169922
    Abstract: Certain example embodiments of this invention relate to evacuation and sealing techniques for VIG units, and/or multi-chamber vacuum ovens for accomplishing the same. In certain example embodiments, a VIG assembly is inserted into a multi-chamber apparatus to successively reduce the chamber pressure and thus the pressure between substrates comprising the VIG assembly until a final evacuation pressure is reached. Once the final evacuation pressure is reached, a pump-out port or tube of the VIG assembly is sealed forming a VIG unit while the VIG assembly is still in the vacuum chamber. After sealing, chamber pressures are gradually increased to atmospheric while the gap between the substrates of the VIG unit remains at a pressure less than atmospheric which is close to the final evacuation pressure.

  • Publication number: 20180066471
    Abstract: Certain example embodiments of this invention relate to edge sealing techniques for vacuum insulating glass (VIG) units. More particularly, certain example embodiments relate to techniques for providing localized heating to edge seals of units, and/or unitized ovens for accomplishing the same. In certain example embodiments, infrared (IR) heating elements are controllable to emit IR radiation at a peak wavelength in the near infrared (NIR) and/or short wave infrared (SWIR) band(s), and the peak wavelength may be varied by adjusting the voltage applied to the IR heating elements. The peak wavelength may be selected so as to preferentially heat the frit material used to form a VIG edge seal while reducing the amount of heat provided to substrates of the VIG unit. In certain example embodiments, the substrates of the VIG unit do not reach a temperature of 325 degrees C. for more than 1 minute.

    Abstract: Certain example embodiments of this invention relate to a frit slurry paste for use in assemblies (e.g., a vacuum insulated glass unit or a plasma display panel), and methods of making the same. Frit powder, binder material, and a water-based solvent are mixed together to form an intermediate mixture. The frit powder is substantially lead free, and the water-based solvent is provided at a first temperature. Additional water-based solvent is added to the intermediate mixture to form a frit slurry paste. The additional water-based solvent is provided at a second temperature, with the second temperature being lower than the first temperature. The binder material is provided at a concentration of 0.001%-20% by weight with respect to the frit slurry paste or the frit slurry paste absent the frit powder. The frit slurry paste has a bulk viscosity of 2,000-200,000 cps.
