Abstract: A luggage case is provided, and the luggage case includes a case body, a pull rod assembly, and a placing assembly. The placing assembly includes a fixing plate fixedly connected to the pull rod assembly and a rotatable plate rotatably connected to the fixing plate. The case body is provided with a first accommodating cavity, and the pull rod assembly is telescopically connected to the case body; in a situation that the pull rod assembly contracts, the placing assembly enters the first accommodating cavity, and in a situation that the pull rod assembly extends, the placing assembly extends out of the first accommodating cavity. When the pull rod assembly contracts into the case body, the placing assembly is located in the first accommodating cavity, the luggage case is designed artistically, and the placing assembly does not contact with external objects to prevent the placing assembly from being damaged.

Abstract: This invention relates to the Internet of Things (IOT), and discloses a method and apparatus of data filtering in the IOT, where the IOT includes a plurality of sensor devices. The method includes: inputting an application deployed rule; converting the rule into at least one sub-predicate expression having static predicates and dynamic predicates; inputting data collected by the sensor devices; matching the collected data with the static predicates and the dynamic predicates of the sub-predicate expression in sequence; and distributing matched data to the application. In this invention, a rule is divided into static and dynamic predicates, and a match is performed on static predicates before dynamic predicates, so that the speed of predicate match can be improved and fast and efficient data filtering in the IOT can be achieved.

Abstract: A system and a method for efficient service-instance oriented energy management in the IoT are provided. The method comprises: a predicting step for predicting target service instances to be serviced in a subsequent time period based on a service instance stance transition model; a selecting step for selecting an ON-sensor set to be turned on to provide services on which said target service instances are based, according to a critical covering set corresponding to the target service instances, the use history data of sensors in the critical covering set and energy parameters of said sensors; a controlling step for performing, when said time period begins, an ON/OFF control on the sensors in the IoT so that the sensors in the ON-sensor set are turned on and the sensors other than those in the ON-sensor set are turned off; and an updating step for updating the use history data of sensors according to the usage of sensors in said time period.

Abstract: The present invention provides a method and apparatus for forming an image. A controller manages a charger and a developing bias voltage to increase an absolute value of the charging voltage to an image-bearing member and an absolute value of a developing bias voltage to a developer-bearing member to predetermined values in a plurality of steps. The controller controls the developing bias voltage applied to the developer-bearing member; wherein the following relation holds in each of the plurality of steps: |VD|>|Vi|, where VD represents a developing bias voltage applied to the developer-bearing member and Vi represents a charged potential of the image-bearing member. This invention is especially useful for mono-component development using DC voltage as a development driving mechanism.
