  • Publication number: 20060064717
    Abstract: An information processing device and method enable swift extraction of a user's preference. The relevant item evaluation value of the preference is increased based on characteristic information about a moving image content whose replay has been directed, based on characteristic information about a still image content whose replay has been directed, based on characteristic information about a sound content whose replay has been directed, based on information about an executed game content, and based on information about a used network content. The relevant item evaluation value of the preference is decreased based on characteristic information about a deleted content. The invention is applicable to video recorders.

  • Patent number: 4078623
    Abstract: A scaling device for weighing load applied on an elevator car floor to prevent overloading operated by detecting the amount of deformation of rubber insulators mounted under the car floor.Load detecting beams are provided under the car floor to detect the deformation of the rubber insulators, and each end of the load detecting beams is loosely jointed to an opposite side of the car floor.When the rubber insulators deform by the load applied on the floor, the load detecting means subside in conformity to the deformation of the rubber insulators and a load detecting switch mounted below the car floor is switched on by the subsidence of the load detecting beams as the load exceeds the rated load, thereby to stop the operation of the car.
