  • Patent number: 11232664
    Abstract: The present application concerns access control for controlling unlocking of a door (102) at the presentation of credentials (108) at the door. A credentials relay unit (112) and a lock controller (114) are mounted in the vicinity of the door. The credentials relay unit transmits received credentials to a pre-configured, first network address, and in addition transmits a wake-up signal (122) to the lock controller, which upon receipt of the wake-up signal will transmit a request (126) for instructions to a pre-configured, second network address. In response to the request, the lock controller receives unlocking or no-action instructions (128a, 128b), and in case unlocking instructions are received, the lock controller transmits an unlocking signal (132).

  • Publication number: 20210272555
    Abstract: A method for training an alarm system to classify audio of an event, wherein the alarm system is connected to a neural network trained to classify audio as an event type, the method comprising the steps of: receiving audio recorded during a first period of time; transmitting the audio to an external unit; receiving data from the external unit indicating a sub-period of time of the audio and data indicating an event type of the indicated sub-period of time of the audio; and re-training the neural network by inputting a sub-period of the audio corresponding to the indicated sub-period of time of the audio and using the indicated event type as a correct classification of the sub-period of the audio.

  • Patent number: 10685557
    Abstract: The present invention relates to an emergency notification system where indicators are mounted on or in a building in such a way that optical or thermal signals emitted from the indicators form a time-variant indication detectable outside the building of an emergency event taking place inside the building. Sensors detecting a predetermined sound are mounted inside the building and are each connected to a nearby indicator. When a sensor makes a detection, it sends event information to its associated indicator which will prompt the indicator to emit a first optical or thermal signal. Based on a signal from a timer connected to the indicator, a property of the first signal will change after a certain time has passed, thereby providing the time-variant indication.

  • Patent number: 10531058
    Abstract: A method and assembly produce color images of a scene captured by an image sensor exposed to visible light as well as IR radiation. A first image is captured with a first proportion of an iris aperture covered by an IR-cut filter. A first amount of radiation captured in the first image is determined and a second image captured with a second proportion of the iris covered by the IR-cut filter. A second amount of radiation captured in the second image is determined and a proportion of IR radiation is calculated in the scene based on the first amount of light, the second amount of light, the first IR-cut filter proportion, and the second IR-cut filter proportion. An IR contribution is removed from an image by using the calculated proportion of IR radiation.

  • Patent number: 10029811
    Abstract: The present invention concerns a method of splicing two sealing strips and a sealing strip formed by the method. The sealing strip is placed at longitudinal edges of a packaging material web, used for packaging containers for liquid foods. The sealing strips to be spliced are cut each forming an oblique edge of about 45°, as seen in plan view. The oblique edges are then placed one on top of the other forming an overlapping area. The overlapping area is in the form of an oblique band having a length of about 3 mm. The ends of the sealing strips are then fused together by heating both from one side at the overlapping area.

  • Publication number: 20170257377
    Abstract: A method and a device for delegating access rights in a system which is configured to handle access rights of users to resources in the system is disclosed. The method comprises assigning a first access right to a first user; appointing a pool of one or more users serving as deputies for the first user; checking if the first user, during a predefined period of time, has refrained from performing a predefined activity with respect to the resources; and if so, delegating the first access right to a user in the pool.

  • Patent number: 9057308
    Abstract: Embodiments of a heating system maintains the temperature of a fuel additive (e.g., AUS32) at and/or above freezing temperature to avoid crystallization. The heating system can form a fluid circuit with one or more coaxially arranged sleeves disposed about hoses that transport the additives. The fluid circuit can also include a central compartment that encloses a flow meter. A fluid heater couples with the fluid circuit to provide heating fluid, e.g., to the central compartment. The heating fluid disperses throughout the heating compartment and into the sleeves, thereby direction heating fluid in thermal proximity to the hoses and other components that handle the fuel additive.

  • Publication number: 20140097577
    Abstract: Embodiments of seal device prevent migration of vapor into compartments that house electronics in a fuel dispensing unit. These embodiments deploy about conduits in a vapor barrier to seal gaps between the conduit and opening in plates of the vapor barrier and/or other components that separate the electronics from fuel-handing components. In one or more embodiments, the sealing device forms a radial seal about the conduit and a planar seal with the vapor barrier, where the sealing device is configured to maintain the planar seal and to allow relative movement of the conduit with respect to the vapor barrier in the opening. This relative movement can occur as a result of connection of the conduit to the fuel-handling components, e.g., a motor that can change position due to operation and/or natural settling of the support structure that supports the motor in the dispensing unit.
