Abstract: A method for unlearning a learnt preference for a lighting system, wherein the method comprises: monitoring one or more feedbacks of a user during a time period, determining whether the one or more feedbacks are related to a light setting of the lighting system or not, assigning a likelihood value to the one or more feedbacks based on the determination, training the machine to learn the user's preference related to the light setting based on the monitored one or more feedbacks, rendering an inferred light setting from the trained machine, receiving a dissatisfaction input from the user indicative of a dissatisfaction level of the user related to the inferred light setting, and if the user's dissatisfaction level exceeds a threshold, removing the one or more feedbacks from the trained machine based on the likelihood value.

Abstract: A method for training a machine for automatizing lighting control actions, wherein the method comprises the steps of: controlling one or more lighting devices to render a first light effect based on a first set of control parameters; controlling the one or more lighting devices to render a second light effect based on a second set of control parameters by transitioning over a transitioning time period from the first light effect to the second light effect; receiving a feedback from a user during a feedback time period; wherein if the feedback has been received within a predetermined time period during the feedback time period; associating the feedback with the transition; and wherein if the feedback has been received after the predetermined time period during the feedback time period; associating the feedback with the second light effect; and wherein the method further comprises training the machine based on the associated feedback.

Abstract: The invention relates to implementing a factory reset to a lighting device. Thereto, the invention provides a lighting device comprising: a directional wireless receiver configured to receive a message within a time period, wherein the message comprises at least one signal comprising a factory reset command from a user device; a controller configured to implement a factory reset of the lighting device if a respective signal of said at least one signal is received within a respective predefined angular range relative to the lighting device.

Abstract: The present invention relates to fast start-up of powered devices (22) connected to a power sourcing equipment (10') in a Power over Ethernet system (100). A stored voltage-current profile of an initial powering phase of a powered device (22) is provided. A voltage level provided to the powered device (22) in a subsequent initial powering phase of the powered device (22) is adjusted as long as a value corresponding to a current voltage level of a voltage-current profile of the subsequent initial powering phase deviates less than a predetermined threshold level from its corresponding value of the stored voltage-current profile of the initial powering phase of the powered device (22) and until a predetermined voltage level is reached. This can allow detecting whether a previously connected powered device (22) was replaced by another powered device (22) and to immediately start-up an unchanged powered device (22) with previously used operation parameters.
