Abstract: Closed loop control of a multimedia system may be achieved with a control space that includes at least two control axes. In each control axis, a coordinate on the axis may indicate a degree to which a multimedia scene facilitates or is perceived to facilitate a user state or a degree to which the user state is achieved. For example, the two control axes may be focus and restoration. A user may provide input that specifies a target state. The target state may be different than, or the same as, the user's current state. The system may select a scene that has coordinates, in the control space, that are closest, by at least a threshold, to the target state, and present the scene to the user. Sensors in the system may measure a user state that results from presenting the scene. The system may revise the scene's coordinates accordingly.

Abstract: The present invention relates to a technology for managing discontinuous reception (DRX). DRX cycles of different cycle lengths are configured according to service types of UE. If it is identified that the user equipment (UE) initiates a voice service, a relatively short first long DRX cycle is configured for the UE or the UE is instructed to deactivate DRX; and if it is identified that the UE does not perform a voice service, a relatively long second long DRX cycle is configured for the UE. The UE performs corresponding receiver on/off control according to the configured long DRX cycle, so as to receive downlink data or hibernate. According to the solution provided in the present invention, a DRX cycle of UE can be flexibly configured, so that a better balance between power consumption reduction of the UE and user experience improvement can be achieved.

Abstract: In exemplary embodiments of this invention, one or more I/O devices accept input from a human user. The input is indicative of a value for each control variable in a set of separate control variables. A computer analyzes the input and outputs control signals to specify a set of separate setpoints. Dimmers adjust the intensity or color of a set of luminaires according to the setpoints. The number of separate control variables is much less than the number of separate setpoints. Having a human control a small number of control variables, in order to control a much larger number of separate luminaire setpoints of luminaires, has at least two advantages: control is faster and control is more intuitive. In illustrative implementations, the luminaire setpoints that are being controlled are not functions of each other.
