Abstract:
본 발명은 스마트 프로젝터 시스템에 관한 것이다. 보다 상세하게는 통상적인 빔 프로젝터에 동작인식 카메라를 연동함으로써, 리모컨으로 프로그램을 제어하는 일반적인 제품들과 달리, 손동작 또는 팔동작을 인식하여 프로그램을 제어할 수 있으므로 자연스러운 영상 구현이 가능하고, 리모컨의 분실 위험과 배터리 문제를 해결할 수 있으며, 강의실이나 교실의 추가적인 공사가 불필요하고, 공간을 많이 차지하지 않을 뿐만 아니라, 초보자의 접근성이 우수하고 업그레이드가 간편하며, 스마트 강의실 구축, 원격 화상회의 시스템, 원격 환자진료, 고령화 사회에 맞춘 원격 SNS 프로그램 등으로 널리 적용될 수 있는 스마트 프로젝터 시스템에 관한 것이다. 이를 위해 본 발명은 사용자 신체의 제스처 정보를 인식하여 드로잉 모드와 스크린 리셋을 제어하고, RGB 영상과 깊이(Depth) 영상을 생성하는 동작인식 카메라; 동작인식 카메라와 전기적으로 연결되어, 동작인식 카메라가 생성한 RGB 영상과 깊이 영상을 전송받아 디스플레이할 영상과 조합하여 출력영상을 생성하는 PC; 및 PC와 전기적으로 연결되어, PC로부터 출력영상을 전송받아 스크린에 투사하는 빔 프로젝터를 포함하는 스마트 프로젝터 시스템을 제공한다.
Abstract:
The present invention relates to an air barrier formation device for shower facilities. To achieve purposes and effects of leading water to the bottom without water splashing to the outside during a shower and providing heat after the shower to dry the moisture, an air barrier formation device for shower facilities comprises a centrifugal compressor (10), a solenoid valve (20), a first pneumatic distributor (30), a nozzle section (40), an air guide section (50), a control unit (60), air supply pipes (AD1-AD6), a second pneumatic distributor (70), a heating unit (80), and a warmth discharge section (90). A wind pressure adjuster (70a) is further provided in the second pneumatic distributor (70) to reduce compressed air of 17 to 20 m/sec transmitted from a two-way solenoid valve (20) to compressed air of 5 to 10 m/sec, the nozzle unit (40) is provided to be supported by the air guide section (50) by arranging three curved round tubes (41a, 41b, 41c) in a ″C″ shape on the bottom surface of a ceiling panel (P), and a plurality of nozzles (42) are provided in common in each of the three curved round tubes (41a, 41b, 41c) at regular intervals. An end portion of the air guide section (50) is configured to have a tapered structure which gets narrower toward a lower part such that compressed air injected from the nozzles (42) can be generated in a thickness of 10 to 15 mm, wherein the thickness of the compressed air can be adjusted by an adjusting member (52).
Abstract:
The present invention relates to a safety chopper, and more specifically, to a safety chopper which closes the chopper having a grid-shaped cutter (30) attached thereto and chops food positioned at the lower part (12) of the chopper, thereby enabling a user to chop food within a short time while preventing the user from getting hurt when cooking. The present invention has a purpose of securing the safety and speed as the conventional method of cutting many times has the disadvantage of taking a long time and possibly injuring hands.
Abstract:
A method of manufacturing Lentinus edodes(shiitake) extract which is beneficial in relieving constipation by extracting shiitake, Schizandra fruit, Licorice rot and ginger in a loess room is provided to obtain the Lentinus edodes extract exhibiting an excellent effect of preventing and improving constipation in vitro tests using animals. Lentinus edodes extract is prepared by the steps of: mixing 93 to 99.7% by weight of dried shiitake, 0.1 to 3% by weight of Schizandra fruit, 0.1 to 2.5% by weight of Licorice root and 0.1 to 1.5% by weight of ginger; mixing the herbs and water in a weight ratio of 1: to 15 to 25; and extracting at 100 to 120deg.C for 1 to 5hr. The dried shiitake is obtained by drying for 6hr in a natural state immediately after harvesting and at 35 to 36deg.C for 24hr in a loess room which is constructed with loess mud yellow soil. The Lentinus edodes extract has a pH of 4.7 to 4.9.
Abstract:
A method for making functional fruit jam containing green tea is provided to enrich the taste of fruit jam while keeping its physical/chemical properties and to enhance the nutritional value. A method for making functional fruit jam containing green tea comprises: mixing 40~70wt% of fruit, 0.1~0.5wt% of green tea leaves or green tea extract, and 30~60wt% of sugar, based on the total weight 100%; stirring the mixture at 50~60°C; and then concentrating it to 64Brix in a vacuum tank having a vacuum pressure of 75cmhg. In the leaves of green tea, they are added in the mixing process after grinding, and therefore a consumer can see the green tea of a particular shape. In the extract of green tea, it is added by mixing green tea and distilled water in a ratio of 1:20(w/v), settling the mixture at normal temperature for 24hr, extracting the settled mixture, and filtering the extract by using a filter.
