Abstract:
A chipset package structure includes a carrier, a plurality of pinouts, at least one semiconductor package preforms, at least one electromagnetic shielding layer and a protective layer. The pinouts are disposed on the carrier. The semiconductor package preforms is disposed on the second surface of the carrier and electrically connected to the pinouts. The electromagnetic shielding layer is disposed on the semiconductor package preforms and the electromagnetic shielding layer. At least one of the electromagnetic shielding layers comprises a carbon nanotube film structure. The protective layer covers the electromagnetic shielding layer.
Abstract:
A method applied in a display apparatus is provided. The display apparatus includes a first screen, a second screen, power signal means. The first screen is volatile. The second screen is non-volatile. The power signal means generate a power off signal in response to a user operation. The method includes: determining whether a power off signal is received; displaying a user interface on the first screen if the power off signal is received; controlling the display on the second screen in response to a user selection on the operation interface; generating a shutdown signal; and powering off the first screen, and the second screen when receiving the shutdown signal.
Abstract:
A set-top box is provided. The set-top box includes a network interface, a wireless communication unit, and a processor. The set-top box connects to a network server through the network interface. The set-top box communicates with a portable device. The processor receives a play request signal including at least one keyword from the portable device through the wireless communication unit. Searches the network server to find at least one multimedia file through the network interface according to the at least one keyword included in the play request signal. Downloads the at least one multimedia file found from the network server, and transmits the downloaded portion of the at least one multimedia file to the portable device through the wireless communication unit.
Abstract:
A projection device includes a base, a desk lamp, a projector, a supporting member, and a fastener assembly. The desk lamp defines a first hole. The projector defines a second hole aligned with the first hole of the desk lamp. One end of the supporting member is connected to the base, and another end of the supporting member is connected to the desk lamp. The fastener assembly includes a bolt and a nut. The nut is fixed in the projector. The bolt is capable of passing through the first hole and being screwed into the nut via the second hole to connect the projector to the desk lamp.
Abstract:
A method for correcting keystone distortion is provided. The method is applied on a projector capable of correcting keystone distortion. The apparatus includes an angle detecting unit and a storage unit. The angle detecting unit detects an inclined angle and outputs a voltage value corresponding to the detected inclined angle. The storage unit stores a relationship between the inclined angles and the voltage values. The method includes determining the inclining angle according to the voltage value and the stored relationship; calculating the ratio of the length of the upper side of the projection area of a source image projected onto a projection surface to the length of the lower side of the projection area of a source image projected onto the projection surface, and inversing the ratio to determine a correction coefficient; and modifying the source image to display the source image onto the projection surface.
Abstract:
A filter includes: a container; at least one barrier, an input device and an output device. The at least one barrier divide the space of the container into at least two resonant cavities. Each resonant cavity has a harmonic oscillator disposed therein. The harmonic oscillators includes a supporter and a carbon nanotube structure disposed on a surface of the supporter.

Abstract:
A wrist worn electronic device includes a main body having a processor and a receiving member electrically connected to the processor. A belt includes an electronic component and a connection member electrically connected to the electronic component. The connection member is used to engage the receiving member, to connect the belt to the main body and electrically connect the electronic component to the processor.
Abstract:
A wrist worn electronic device includes a hollow casing including an internal protruding tab defining a groove. A display panel is arranged within the hollow casing. A touch panel is arranged on the display panel and is larger than the display panel. The touch panel includes a margin portion around the display panel and rests on the protruding tab. The margin portion is connected to the protruding tab by waterproof adhesive. The groove accommodates waterproof adhesive to form a sealing layer to prevent water from entering the casing.
Abstract:
An electronic device for transmitting warning information to a monitoring device is provided. The monitoring device includes a radio frequency transmitting unit transmitting a wireless signal. The electronic device includes a radio frequency receiving unit, a detector, a wireless transmitting unit, and a processor. The radio frequency receiving unit receives the wireless signal transmitted by the radio frequency transmitting unit when the distance between the radio frequency transmitting unit and the radio frequency receiving unit is less than a preset value. The detector detects the movement or the oscillation of the electronic device. The radio frequency receiving unit generates an anomalous potential to signal the processor to enable the detector when not receiving the wireless signal transmitted through the radio frequency transmitting unit. The processor transmits the warning information to the monitoring device through the wireless transmitting unit when the detector detects that the electronic device moves or oscillates.
