摘要:
A commodity RFID system is used for automatically measuring levels of soil moisture in planting containers. A large number of planting containers are used to grow pots in soil in a greenhouse. An RFID reader interrogates passive RFID tags affixed to the planting containers. The RFID reader can be attached to a robotic arm configured to move above multiple rows and columns of containers. Signal features (e.g., MRT, RSS, DMRT) of specific passive RFID tags affixed to specific ones of the containers are automatically monitored, based on the wireless interrogation of the specific tags by the reader. Soil moisture levels of specific containers are then automatically determined based on the signal features of the attached RFID tags, and effects of soilure moisture on electromagnetic fields of antennas of passive RFID tags.

In various embodiments, systems and methods are presented for providing resources by way of a platform as a service in a distributed computing environment to perform a job. The system may be comprised of a number of components, such as a task machine, a task location service machine, and a high-level location service machines that in combination are useable to accomplish functions provided herein. It is contemplated that the system performs methods for providing resources by determining resources of the system, such as virtual machines, and applying auto-scaling rules to the system to scale those resources. Based on the determination of the auto-scaling rules, the resources may be allocated to achieve a desired result.

Systems and methods are presented for providing resources by way of a platform as a service in a distributed computing environment to perform a job. Resources of the system, job performing on the system, and schedulers of the jobs performing on the system are decoupled in a manner that allows a job to easily migrate among resources. It is contemplated that the migration of jobs from a first pool of resource to a second pool of resource is performed by the system without human intervention. The migration of a job may utilize different schedulers for the different resources. Further, it is contemplated that a pool of resources may automatically allocate additional or fewer resources in response to a migration of a job.

Systems and methods are provided for assigning and associating resources in a cloud computing environment. Virtual machines in the cloud computing environment can be assigned or associated with pools corresponding to users as dedicated, standby, or preemptible machines. The various states provide users with the ability to reserve a desired level of resources while also allowing the operator of the cloud computing environment to increase resource utilization.

Systems and methods are provided that enable a general framework for partitioning application-defined jobs (e.g., computation) in a scalable environment. The general framework decouples partitioning of a job from the other aspects of the job. As a result, the effort required to define the application-defined computation in a scalable environment is reduced or minimized, as the user is not required to provide a partitioning algorithm. The general framework further allows a user to provide load balancing conditions to allow for modification of how partitions are assigned.

Embodiments of the present invention relate to systems, methods and computer storage media for facilitating the structured storage of binary large objects (Blobs) to be accessed by an application program being executed by a computing device. Generally, the manipulation of Blobs in a structured storage system includes receiving a request for a Blob, which may be located by way of a Blob pointer. The Blob pointer allows for the data, such as properties, of the Blob to be identified and located. Expired properties are garbage collected as a manipulation of the Blob data within a structured storage system. In an embodiment, the Blob is identified by a key that is utilized within a primary structured index to located the requested Blob. In another embodiment, the requested Blob is located utilizing a secondary hash index. In an additional embodiment, the Blob is locate utilizing a file table.

An auto focus device of a mobile communication apparatus is disclosed. The auto focus device comprises a voice coil motor, a first driving circuit and a second driving circuit. The voice coil motor comprises a floating movable device and a lens in the floating movable device. The first driving circuit drives the voice coil motor so that the floating movable device moves inside the voice coil motor to zoom in/out and focus the lens on image sensors when the camera function is activated. The second driving circuit drives the voice coil motor to fix the floating movable device inside the voice coil motor and cover the image sensors.
