  • Publication number: 20190386157
    Abstract: A layered semiconductor structure with a width in a lateral direction, having an operating area covering part of the width of the semiconductor structure, comprises a semiconductor substrate with majority charge carriers of a first polarity; and a first dielectric layer with inducing net charge of the first polarity on the semiconductor substrate. An induced junction is induced in the semiconductor substrate by an electric field generated in the semiconductor substrate by the inducing net charge. The semiconductor structure is configured to confine the electric field generated in the semiconductor substrate in the operating area.

  • Publication number: 20190270615
    Abstract: A method for installing a hoisting rope into an elevator system includes providing a rope reel storing a hoisting rope; and thereafter unwinding a section of the hoisting rope from the rope reel; and arranging the section of the hoisting rope unwound from the rope reel to pass from the rope reel to a rim of a drive wheel of the elevator and around it such that it rests against said rim; and thereafter rotating the drive wheel with a motor for driving the hoisting rope to run around the drive wheel.

  • Patent number: 10367498
    Abstract: An electronic device includes at least one electronic component, a gradient heat-flux sensor GHFS based on thermoelectric anisotropy and conducting heat generated by the electronic component, and a controller adapted to manage electrical current of the electronic component at least partly on the basis of an electrical control signal generated by the gradient heat-flux sensor and proportional to a heat-flux through the gradient heat-flux sensor. Therefore, the electrical current and thereby also the heat generation of the electronic component are managed directly on the basis of the heat-flux generated by the electronic component. Thus, the electrical current can be managed without a need for voltage and current measurements which may be challenging to be carried out with a sufficient bandwidth especially when the switching frequency of the electronic component is on a range from hundreds of kHz to few MHz.

  • Publication number: 20190219530
    Abstract: The invention relates to a method for inspecting quality and/or condition of an elongated composite member, which is a load bearing member of a rope of a hoisting apparatus, such as an elevator, or a precursor of such a load bearing member, the method comprising providing an elongated composite member; and changing the temperature of said elongated composite member by heating or cooling said elongated composite member via a flank thereof; and scanning said elongated composite member from a lateral side thereof with a thermal imaging device after said changing of the temperature; and creating thermographic images of said elongated composite member.

  • Publication number: 20070197229
    Abstract: A system for indicating the relative direction of a target object or location as determined from the current position of a wireless communication device. The system employs Direction of Arrival determination using an antenna array for indicating the direction of a target device and includes facilities to activate a location-indicating transmission in a target device, the ability to request that a location-indicating transmission be activated in a remote target device, relevant information reception from a target device and the display of all potential target devices within effective transmission range of the wireless communication device.
