  • Publication number: 20240385441
    Abstract: A heads-up display system includes a polarizing beam splitter, a fold mirror, a heads-up display mirror, and a picture generating unit configured to emit a picture light. The polarizing beam splitter, the fold mirror, and the heads-up display mirror define a cavity, and the picture generating unit is disposed outside the cavity. The picture light emitted from the picture-generating unit enters the cavity after being transmitted by the polarizing beam splitter a first time, and the picture light exits the cavity after being transmitted by the polarizing beam splitter a second time.

  • Publication number: 20100170057
    Abstract: Provided is a high-efficiency slim vacuum inhalation apparatus which cools heat generated from heat-generation sources without using particular heat radiation components, and a robot cleaner employing the same. The vacuum inhalation apparatus does not need particular heat radiation components since an impeller is closely adhered to a rotational shaft by a pair of washers and an impeller bushing, to thus avoid from sliding, and since an inhalation efficiency which is caused by a brushless direct-current (BLDC) motor increases, and thus power consumption decreases. Further, since a BLDC motor is incorporated in a vacuum inhalation apparatus so that the vacuum inhalation apparatus can be implemented into a slim type, a robot cleaner can be also compactly realized into a slim type.
