형광필름과 파장 필터를 이용한 호겔 얼라인 장치가 제공된다. 본 발명의 실시예에 따른 호겔 얼라인 방법은, 형광 매질이 부가된 매질에서 호겔 영역에 신호광과 참조광을 조사하고, 형광 매질에서 방출되는 광을 필터링하며, 필터링된 광을 촬영하여 관측 영상을 생성한다. 이에 의해, 산란광/노이즈 등으로 인하여 호겔 영역을 깨끗하게 관측할 수 없었던 문제에서 기인한 미세 호겔 정렬의 어려움을 해결할 수 있게 되어, 궁극적으로 고해상도의 호겔을 프린팅 할 수 있도록 하여 인쇄된 홀로그램의 품질을 높일 수 있게 된다.
Abstract:
This standard defines the interface for wireless power transfer to multiple devices (including one device) that require charging within several meters. In order to provide WPT for multi-devices, functionalities, system structure, primitives, frame format, and procedures are defined. This standard selectively utilizes various frequency bandwidths ranging from the low frequency of 50 kHz to the high frequency of 15 MHz for wireless power transfer. For system control, it requires supports of the signalling by which data and control signals can be exchanged. This standard can be applied to a multimedia industrial field for use of batteries such as mobile terminals, laptops, portable multimedia players, etc.

Abstract:
A system and method is disclosed for controlling congestion in communications between an RSE and multiple OBEs in a DSRC system. In certain embodiments, a system and method for controlling congestion in communications between an RSE and multiple OBEs includes determining a priority level for each of multiple OBEs with respect to reserving a channel between each OBE and an RSE. Based on this determination, each OBE is assigned a waiting period based on their respective priority levels. The OBEs then send requests to reserve a channel to the RSE after waiting the assigned waiting periods.
