The present invention relates to a method for delivering a push notification and a push notification server for performing the method. In the push notification delivery method, by a push notification server, a push notification message is received from a push notification server application. By the push notification server, the push notification message is sent to a push notification client registered in association with the push notification server application. If the push notification message is not sent, the push notification message is stored in a transmission queue within the push notification server and is resent to the push notification client, or an update, expiration or cancellation of the push notification message is processed. A push delivery state of a push notification message, sending of which has finally failed, is changed to a delivery failed state, and failure results are transferred to the push notification server application.

Method for delivering push notification and push notification server for performing the same

Disclosed herein are a push notification-based remote control method and an apparatus for the remote control method. A push notification client includes a message receiving module for receiving a push notification message from a push notification server. A rule interpretation module determines whether a remote control rule is present in the push notification message. A rule registration management module is configured to, if it is determined that the remote control rule is present in the push notification message, register the remote control rule in a rule execution list. A rule execution module executes the remote control rule.

A method of creating a global coordinate of a polyhedral hollow frame includes a first step of providing a plurality of transmitters on a reference surface in the hollow frame, providing a plurality of reference sensors to create the coordinate of the reference surface, and creating a local coordinate frame of the reference surface on the basis of the positional coordinates measured by the reference sensors; a second step of providing reference sensors at common points of a first vertical surface neighboring to the reference surface to measure and store the coordinates of the common points; a third step of providing a plurality of transmitters and reference sensors on the first vertical surface neighboring to the reference surface to create a local coordinate frame of the first vertical surface; a fourth step of transforming the local coordinate frames created at the first and the third steps into a global coordinate frame using the coordinates of the common points measured at the second step; a fifth step of repeatedly performing the second step to the fourth step on remaining vertical surfaces of the polyhedral hollow frame to transform the respective local coordinate frames into a unified global coordinate frame; a sixth step of providing transmitters on an upper surface neighboring to each vertical surface to obtain the relationship between the global coordinate frame and a local coordinate frame of the upper surface using the coordinates of the common point; and a seventh step of creating and applying a global coordinate frame using the relationship obtained at the sixth step.

A three-dimensional measurement system using an IGPS includes a rescale bar having linear scales thereon, a linear encoder for measuring an absolute length within which the linear encoder moves on the rescale bar, a plurality of optical transmitters that radiates pan beams, and a vector bar having one end attached to the linear encoder, and having a receiver to detect the pan beams radiated from the optical transmitters, the vector bar acquiring coordinates of two points where the vector bar moves by using the receiver, and measuring a relative length from the coordinates. A ratio between the absolute length and the relative length is applied in rescaling an actual distance between two positions to be measured.
