  • Publication number: 20090231122
    Abstract: A mobile security monitoring method and system and an alarm security node in the system for intelligent security system, where said intelligent security system is activated by a breach in a security zone. This breach will start a video monitoring/recording sequence that is sent out via the broadband to an alarm center. The alarm center forwards this alarm information to a user as SMS/MMS information through a mobile network. The user can view and evaluate what is going on at the security zone and can decide what action to initiate. This will minimize a false alarm generation and thus cut down the costs of follow thru of the false alarm (s) by i.e. an alarm security provider. For security and cost reason, the intelligent security system is the only client of the server-side alarm center. The concept is to use existing IT infrastructure at the security zone for user like W-LAN, broadband, GPRS and mobile devices.

  • Patent number: 7389328
    Abstract: The invention relates to end user controlled handling of personal data on e.g. the Internet. Web services are offered in a controlled manner from a service broker (250) provided with appropriate security mechanisms. The broker contains end user controlled policies related to personal data/services, while the actual data is arranged at different locations in the network. Web service information is published in an open registry (256) at the broker. When an application provider (220) finds a desired service in the registry, its service request is guided to the appropriate service broker. The broker returns the policy for the requested service, whereafter the service provider (240) can be contacted, preferably through an encapsulated SOAP message. A preferred embodiment performs common sign on authentication when a new application is contacted.

  • Publication number: 20080141337
    Abstract: In the setting of policies for personal data, instructions originating from a primary user and defining a privacy policy for a selected piece of personal data are communicated, via an application unit (220), to a privacy-setting node (258) of a service broker (250). The instruction define possible data providers (240) for the data. The policy is stored at a database (254) in a privacy tree for the primary user comprising hierarchically arranged personal data with associated policies. Upon receiving a request for the personal data, the privacy-setting node determines whether there is a privacy policy defined from the data by checking the privacy tree of the primary user If there is a policy for a requested data, it selects a data provider among the possible data providers and returns a response to the application unit, providing access to the requested personal data at this provider.

  • Publication number: 20060196498
    Abstract: A motor housing having an integral cleaning fluid heating reservoir for use in a range hood. The motor housing comprises top and bottom sections connectable to one another. The top section has an upper surface and a perimeter side surface. A floor and a pair of end surfaces extend substantially perpendicularly from the perimeter side surface. An outer side surface extends from the floor and pair of end surfaces such that the outer side surface is spaced apart from the perimeter side surface, thereby forming the heating reservoir. The motor housing is made substantially of plastic with at least one portion of heat conducting material such as metal formed in the perimeter side surface in order to conduct heat from the motor housing interior to cleaning fluid within the heating reservoir.

  • Patent number: 6926000
    Abstract: A range hood having an improved grease collecting motor housing and improved fan and motor connection. Housing openings are defined by circular walls projecting vertically into the housing acting to collect grease within the housing. A flange depends radially outwardly from, and at an angle to, the circular wall. Air entering the housing via the fan deflects off the flange and prevents turbulent air within the housing from exiting the housing in the space located between the circular wall and the fan. The fan connection is comprised of a threaded recess in a shaft of the motor and a fan cap having a threaded bolt. The shaft is inserted through an aperture in the fan and the fan cap threadingly connected to it. A tray attachable to the housing, and defining an air intake opening has an improved mating relationship with a lower panel of the range hood.

  • Patent number: 6895957
    Abstract: A range hood cleaning assembly having a primary reservoir in fluid communication with a range hood motor housing. Wash fluid from the primary reservoir may be dispersed against grease laden surfaces of the fan and motor housing where it drains back to the primary reservoir, optionally via a secondary reservoir. Grease washed by the fluid floats to the top of an outlet chamber in the primary reservoir and out a drainage hole to an external receptacle. Alternatively, the grease may drain from the top of the secondary reservoir to the external receptacle. The primary and secondary reservoirs are shaped and sized to fit below the motor housing.

  • Patent number: 6880551
    Abstract: A range hood cleaning fluid heating chamber that may be connected to a motor housing in a range hood. The cleaning fluid heating chamber comprises an outer shell, which defines an enclosure that is shaped and sized to fit along a portion of the periphery of the motor housing, preferably in abutment. The heating chamber has an inlet and an outlet and cleaning fluid within the heating chamber draws heat from the motor housing when the range hood is in operation. Alternatively, the cleaning fluid heating chamber may comprise an outer shell and a length of piping sandwiched between the periphery of the motor housing and the outer shell. As a further alternative, the heating chamber may simply take the form of a conduit adjacent the motor housing. The heated cleaning fluid may be used for cleaning surfaces within the range hood.

  • Patent number: 6851422
    Abstract: A cleaning fluid heating reservoir and motor assembly for a range hood having a motor housing enclosure mounted within the enclosure defined by the hood body. The heating reservoir is shaped and dimensioned to be in abutment with, or is integral with, the motor. The motor is mounted within the motor housing. The reservoir may occupy space between the top of the motor and the hood body, between the perimeter of the motor and a fan attached to the motor, or between both. Conduits connected to the heating reservoir inlet and outlet pass through the motor housing to an intermediate reservoir located within the range hood. Fluid from the intermediate reservoir is pumped to the heating reservoir and back to the intermediate reservoir thereby drawing heat energy from the motor when in operation. Cleaning fluid may also be pumped from the intermediate reservoir to areas requiring cleaning.
