20090161309 | Removable hard drive casing - A removable hard drive casing for rapidly integrating a hard drive into a computer case, comprising a fixing frame, a hard drive tray and a protective cover. The fixing frame comprises an opening and a receiving space. The hard drive tray can hold the hard drive therein and be inserted and integrated into the receiving space through the opening of the fixing frame. The hard drive tray is provided with a rack on one of the outer sidewalls thereof. The protective cover is a plate-like cover and has two opposite axle ends on the sidewalls thereof, pivotally connected to the opening of the fixing frame. The protective cover further has an arcuate rack corresponding to the rack provided on the outer sidewall of the hard drive tray. The hard drive tray can be moved for a predetermined distance to and from the inside of the fixing frame by means of the arcuate rack on the protective cover driving the rack on the hard drive tray when the protective cover is opened and closed. | 06-25-2009 |
20150061331 | BREATHABLE SEAT CUSHIONING AND SEATING DEVICE FOR CHILDREN - A breathable seat cushioning device includes a seat body, a plurality of air conduits, an air permeable body, a fan module, and a heater. The seat body has a plurality of receiving grooves longitudinally arranged thereon. The air conduits have a plurality of air outlets arranged thereon. The air conduits are disposed in the receiving grooves. The air permeable body covers a surface of the seat body. The fan module is connected to the air conduits and has a casing and at least one blade pivotally coupled to the interior of the casing. The heater is arranged inside or outside the fan module. As a result, active ventilation is provided to prevent poor air permeability which can cause unpleasant seating conditions such as stuffy, perspiration, to children sitting on the breathable seat cushioning device. Moreover, warm air flow can be provided during colder environment. | 03-05-2015 |

20090141749 | LASER MODULE - A laser module including a light emitter, a filter, a nonlinear optical crystal, a first temperature adjuster, and a second temperature adjuster is provided. The light emitter emits a first beam. The filter is disposed on a transmission path of the first beam and reflects the first beam. The nonlinear optical crystal is disposed on the transmission path of the first beam and between the light emitter and the filter. The nonlinear optical crystal converts a part of the first beam into a second beam. A frequency of the second beam is larger than a frequency of the first beam. The second beam passes through the filter. The first temperature adjuster is connected with the filter for adjusting a temperature of the filter. The second temperature adjuster is connected with the nonlinear optical crystal for adjusting a temperature of the nonlinear optical crystal. | 06-04-2009 |
20110090177 | OPTICAL TOUCH SYSTEM - An optical touch system includes a non-visible light source, a screen, a first and second polarizing elements, and an optical detector. The non-visible light source emits a non-visible beam. A part of the non-visible beam passes through the screen disposed in a light path of the non-visible beam. The touch object reflects the part of the non-visible beam into an object beam when a touch object approaches or touches the screen, and the object beam passes through the screen. The first polarizing element is disposed in the light path of the non-visible beam and between the non-visible light source and the screen. The optical detector is disposed in a light path of the object beam, and senses the object beam. The second polarizing element is disposed in the light path of the object beam passing through the screen and between the screen and the optical detector. | 04-21-2011 |
20130162957 | PROJECTION APPARATUS AND PROJECTION LENS THEREOF - A projection lens including a reflective unit and a refractive unit is provided. The projection lens is disposed between an object side and an image side. The reflective unit is disposed between the object side and the image side and has a negative refractive power. The refractive unit is disposed between the object side and the reflective unit and has a positive refractive power. The refractive unit includes a first lens group and a second lens group. The first lens group is disposed between the object side and the reflective unit and includes at least one cemented lens and an aperture stop. The at least one cemented lens is disposed between the object side and the aperture stop. The second lens group is disposed between the first lens group and the reflective unit and includes at least one aspheric lens. A projection apparatus including the projection lens is also provided. | 06-27-2013 |

20140049813 | PROJECTION LENS - A projection lens configured to form an image from an image source which is disposed at an object side is provided. The projection lens includes a lens group and an aspheric mirror. The lens group has a first optical axis, and an intermediate image is formed by the lens group from the image source. The aspheric mirror has a second optical axis and an aspheric surface. The lens group is disposed between the object side and the aspheric mirror. The aspheric surface faces the lens group and reflects the intermediate image to form the image at an image side. The first optical axis is not coaxial with the second optical axis, and an offset of the image relative to the first optical axis is larger than or equal to 100%. | 02-20-2014 |
