  • Patent number: 11990755
    Abstract: A method for detecting power oscillation in an electric power grid, wherein the method comprises: integrating a filtered signal on a first interval, the filtered signal being associated with the electric power grid; based on the integration of the filtered signal on the first interval, determining a positive half-period area of the filtered signal and a negative half-period area of the filtered signal, one of the positive half-period area and negative half-period area being immediately subsequent to the other one; and determining that a power oscillation in the electric power grid is detected if the following two conditions are met: a sum of the positive half-period area of the filtered signal and the negative half-period area of the filtered signal is below a first threshold; and the absolute value of one of the positive half-period area and negative half-period area is above a second threshold.

  • Patent number: 10433080
    Abstract: According to an embodiment, a hearing aid is disclosed. The hearing aid includes a housing, a light guide member, a first light source, and a second light source. The housing includes electronic components configured to generate a perceivable modulated signal in response to a received sound. The perceivable modulated signal is configured to produce a hearing sensation to a user of the hearing aid. The light guide member is arranged proximal to and/or within the housing. The first light source configured to emit a first colored light and a second light source configured to emit a second colored light. The first light source and the second light source are positioned within the housing and arranged in relation to the light guide member such that a substantial amount of the first colored light and a substantial amount of the second colored light are adapted to travel through the light guide member.

  • Publication number: 20120233872
    Abstract: A description is given of an apparatus (1) for treating a bed (2) of particulate material which is supported by an aeration bottom (3), subject to the application of a conditioning gas being directed to and flowing up through the aeration bottom (3) and the material bed (2) from an underlying compartment (4) which comprises side walls (5), end walls (6) and a bottom (7). The apparatus is peculiar in that it comprises a space (8) for inspection which extends into the compartment (4) from one of its side walls (5), end walls (6) or bottom (7) and allowing access for a person for visual inspection by direct sight of the compartment (4) through a number of inspection openings (9). Hence it will be possible during the operation of the apparatus to inspect by direct sight the equipment in a significantly extended area of the compartment.
