Provided are a device and method for analyzing spatiotemporal data of a geographical space including one or more regions. The method includes imaging spatiotemporally varying data, selecting a representative image according to each transition state based on a spatiotemporal change in the imaged data, grouping pixels in the selected image by clustering the pixels, and performing group-specific data analyses.

A system for measuring pressure of an in-tank regulator includes a direct-pipe flow path which directly communicates with an inside of a high-pressure container, a high-pressure sensor, of which a portion is movable into the direct-pipe flow path, fastened to and separated from the direct-pipe flow path, and a shut-off valve disposed on the direct-pipe flow path between the high-pressure container and the high-pressure sensor, wherein when the high-pressure sensor is separated from the direct-pipe flow path, the direct-pie flow path is sealed by the shut-off valve.

System for measuring high pressure of in-tank regulator

A solenoid valve includes: an independently movable pilot plunger head; a main seat including a hole, so that gas flows into the solenoid valve through the hole of the main seat; a main plunger being in contact with the main seat; a pilot plunger disposed at top surface of the main plunger inside the solenoid valve, and including a hollow portion inside the pilot plunger; and a pilot plunger head disposed at one side inside the pilot plunger, and having an apex being in contact with the main plunger. The pilot plunger is movable inside the valve, the pilot plunger head is movable inside the hollow portion of the pilot plunger, and the pilot plunger head and the pilot plunger separately move from each other.

Solenoid valve including independently movable pilot plunger head

A device for distributing a load and managing power of a virtual server cluster includes a monitoring unit configured to monitor a load distribution condition on server nodes included in a server cluster and a dynamic state of each of the server nodes, a server node information storage unit configured to store static state information of each of the server nodes, a policy determination unit configured to determine a load distribution policy and a power management policy for each of the server nodes using monitoring information and the static state information stored in the server node information storage unit, and a controller configured to control conversion of each of the server nodes into an active state or an inactive state according to the power management policy, and distribution of a load of a service request requested by a service client to activated server nodes according to the load distribution policy.

Device for distributing load and managing power of virtual server cluster and method thereof
