  • Patent number: 8982756
    Abstract: An intermittent reception control apparatus controls intermittent reception in communication between a base station apparatus and mobile station apparatuses. The intermittent reception control apparatus comprising a control unit that generates DRX parameters, which are intermittent reception parameters, and transmits the generated DRX parameters to the mobile station apparatuses. Further, the DRX parameters include information on the timing at which to cause the mobile station apparatuses to enter an active state and are common to all of the mobile station apparatuses, where the active state is a state where reception of signals transmitted from the base station apparatus is enabled. The intermittent reception control apparatus further comprising a scheduler that transmits to the mobile station apparatuses a DRX command that operates to force these apparatuses to enter an inactive state.

  • Patent number: 7036503
    Abstract: A humidifier having a heat-generating composition for generating steam is disclosed. The humidifier is permitted to fit the face, keeping the humidity high at a space between the face and the humidifier for many hours. A central non heat-generating belt, which functions as a flexible belt, is provided between inner heat-generating regions containing heat-generating composition. Lateral non heat-generating belts, which function as a flexible belt, are provided between the inner heat-generating regions and outer heat-generating regions. The humidifier fits the face by deforming the flexible belts. Thus, the face is kept moisturized by steam discharged from the inner heat-generating regions and the outer heat-generating regions.
