353043000 | GUN, FLASHLIGHT OR BATTERY OPERATED TYPE | 6 |
20090244490 | Mobile Projector Apparatus and Method of Controlling the Same - A mobile projector apparatus includes a light source, a modulation unit modulating light of the light source using a picture signal, a projection lens magnifying and projecting the modulated light of the light source, a battery supplying electric power to the light source, an acceleration measuring unit measuring an acceleration applied to the mobile projector apparatus, a usage state detecting unit detecting whether or not the mobile projector apparatus is in an unused state, and an extinguishing unit extinguishing the light source based on outputs of the acceleration measuring unit and the usage state detecting unit. | 10-01-2009 |
20100141899 | Projection apparatus - A projection apparatus includes a housing, a connector, a control module, and an optical module. The housing provides a battery chamber. An interface aperture is inside the battery chamber. The connector is disposed in the housing and provides a signal transmitting interface located in the interface aperture inside the battery chamber. The control module includes an error-detecting circuit and a microprocessor. The error-detecting circuit is electrically connected to the signal transmitting interface and the microprocessor, and the microprocessor is electrically connected to the signal transmitting interface through the error-detecting circuit. The optical module is disposed in the housing and electrically connected to the control module. | 06-10-2010 |
20110188004 | PROJECTION-TYPE IMAGE DISPLAY APPARATUS - A projection-type image display apparatus includes an imaging light generation portion which generates imaging light, a housing which stores the imaging light generation portion, and a passage region provided in the housing, through which the imaging light emitted from the imaging light generation portion passes. The housing has a movable portion of which dimension in at least one direction varies, and the passage region is stored in the housing by means of the movable portion while imaging light is not projected. | 08-04-2011 |
20110234986 | MINIATURIZED PROJECTION IMAGE DISPLAY APPARATUS - A projection image display apparatus includes: a first casing which includes an image projection unit provided therein and a projection window provided at one end side thereof; and a second casing which has one end side coupled with the other end side of the first casing pivotably around a pivot axis. The first casing and the second casing are switchable between a first condition in which one side surface of the first casing and one side surface of the second casing are aligned opposite to each other and a second condition in which the first casing is pivoted from the first condition around the pivot axis within a plane orthogonal to the pivot axis and thus erected relative to the second casing. | 09-29-2011 |
20160044291 | SMARTPHONE AND EXTERNAL MICRO PROJECTOR THEREOF - An external micro projector comprises a micro projector body. A magnetic block is disposed in the micro projector body. The magnetic block is used for magnetically adhering with a magnetic adhesion device in a smartphone. A Pogo Pin connector is disposed on the micro projector body. The Pogo Pin connector is used for being electrically connected to the smartphone. | 02-11-2016 |
