Abstract: A device and a method for automatic generation of a recommendation for an item p to a user u. The device is at least indirectly connected to an item database containing a user profile database and a user interrelation database. A standard recommender engine accesses the item database and user profile database to calculate a score s(p,u) in a [0,1] interval indicating a “like” degree of an item p for user u based on a user profile of user u. The device further has a content discovery recommender to access the user interrelation database and to find at least users v that have a direct connection to user u to determine a fraction of the users v that know an item p and to generate a recommendation based on the score s(p,u) of item p.

Abstract: The invention relates to a method of controlling a temporal variation of light emitted by an illumination system. The light emitted by the illumination system varies from light having a start color point (14) to light having a target color point (12). The start and target color point are defined in a first color space (XYZ, RGBvid, RGBill), which is perceptually non-uniform. The method according to the invention converts the start and target color point from the first color space to a second color space (Lab, Lch), which is more uniform to the human visual system than the first color space. The method further comprises a step of generating an intermediate color point (34, I1, I2) located on a transition-path (p, p?) within the second color space, an intermediate distance (d) between the start color point in the second color space and the intermediate color point in the second color space not being larger than a threshold distance (26).

Abstract: The present invention relates to controlling switches in a series connection of electrical devices, in particular to a circuit arrangement, and method of operating same, in which a transistor switch (44, 54) is used to control operation of the devices (12, 14). Because the transistor switches need a gate-source voltage difference, but on the other hand are connected with their source (s) and drain (d) to the main circuit branch, this voltage difference is built up by providing a control current (Ii, I2) over e.g. a resistor (42, 52). This control current (Ii, I2) enters the main current (I), which would influence the operation of the devices, e.g. LEDs (12, 14). In order to correct this, the control current (I2) is corrected for the values of one or more upstream control currents (I2), e.g. through adapting the pulse width in pulse width modulation.

Abstract: A user profiling system that receives user command/control selections related to content currently being provided to the user. A processor acts on the command/control selections and also determines whether the command/control selections are volume related command/control selections. In a case where the command/control selections are volume related, the processor utilizes these volume related command/control selections as an input to a user profile of the user profiling system. The user profile may be utilized for providing recommendations of content to the user.
