Abstract: An antenna device and a method for configuring the same are provided. The antenna device includes a grounding metal, a grounding part, a radiating part, a feeding part, a proximity sensor, and a sensing metal. The radiating part is electrically connected to the grounding metal through the grounding part. The feeding part is coupled to the grounding metal through a feeding point. The sensing metal is electrically connected to the proximity sensor. The sensing metal is separated from the radiating part at a distance. The distance is less than or equal to one thousandth of a wavelength corresponding to an operating frequency of the antenna device.

Abstract: A memory management system includes a memory, a processor, a memory access monitoring module and a memory management module. The processor is used to access the memory. The memory access monitoring module includes a first terminal coupled to the processor, and a second terminal coupled to the memory. The memory access monitoring module is used to monitor whether the processor has accessed the memory so as to generate monitor data. The memory management module is used to receive the monitor data and predict when the memory is to be accessed according to at least the monitor data.

Abstract: A remote-controllable electronic device includes a casing, a filter, a sensor, and a shielding element. The casing is formed with a hole where the filter is embedded thereto. The sensor is disposed within the casing and configured to receive a light signal filtered by the filter. The shielding element is disposed in front of the sensor so as to specify a receiving range for receiving the light signal.

Abstract: A projector includes a housing, a projection module installed inside the housing, a connection interface installed on the housing for connecting external devices, and an illumination module installed on the housing for illuminating the connection interface. The projector further includes a switch installed on the housing for switching on the illumination module.

Abstract: An optical machine includes a light pipe, a light pipe holder, and a light pipe covering installed on the light pipe holder in a rotatable manner for covering the light pipe. The optical machine utilizes a hinge connection of the light pipe covering and the light pipe holder so as to provide degrees of freedom of rotation and limit degrees of freedom of translation.

Abstract: A projector having a light-shielding module. The projector comprises a housing, a light engine, and a light-shielding module. The housing has a aperture. The light engine includes a projection lens. The projection lens is disposed in the housing, and relative to the aperture in order to project an image. The light-shielding module has an adjustable light-shielding zone, and is used for selectably shielding the image.
