Abstract:
A light guide plate (LGP) includes a first surface, a second surface, and a plurality of light incident surfaces. The first surface is a light-emitting surface. The light incident surfaces connect the first surface and the second surface. The second surface has a plurality of ring-shaped grooves. Depths of the ring-shaped grooves are gradually decreased from a place close to a center of the LGP towards places close to the light incident surfaces. Each of the ring-shaped grooves has a first ring-shaped side wall surface and a second ring-shaped side wall surface. The second ring-shaped side wall surface is opposite to the first ring-shaped side wall surface and located between a geometry center of the ring-shaped groove and the first ring-shaped side wall surface. The first ring-shaped side wall surface is a tilted surface. In addition, a light source apparatus is also provided.
Abstract:
A paper-made container includes a paper sheet which has a bio-degradable layer coated thereto and an adhesive and bio-degradable glue layer is coated on an underside or a peripheral portion of the paper sheet such that the paper sheet is made to be a container. The glue layer is coated to the paper sheet by way of injection technique so as to reinforce the structural strength of the paper-made container.
Abstract:
A non-isolated power supply device and a method for controlling the same, wherein only one DC voltage bus is adopted and the neutral lines of the input voltage and output voltage are directly connected together. During the periods that the voltage polarities of the input voltage and output voltage are not the same, the power supply device is operated in a flyback mode to avoid the generation of an abnormal current. Otherwise, during the periods that the voltage polarities of the input voltage and output voltage are the same, the power supply device is operated in a boost mode to derive a superior efficiency.
Abstract:
A paper cup assembly includes a paper cup 10 with a bottom piece connected to the lower end thereof and the cup has an open top. A lip portion made of bio-degradable plastic material is formed along the open top by way of injection molding, heat-pressing or high-frequency wave welding. Multiple protrusions are formed on the outside of the cup when forming the lip portion. The cup has a positioning portion and the isolation collar is mounted to the cup and the top portion of the isolation collar is connected to the positioning portion. The lower portion of the isolation collar is fixed to the cup. A gap is defined between the whole isolation collar and the cup. When used to a deep cup, the protrusions are helpful for isolating the heat from the cup.
Abstract:
A light source module includes a transparent element, a plurality of light-emitting devices, and a plurality of light diffusion micro-structures. The transparent element includes a transparent substrate having a light exiting surface and a bottom surface opposite to the light exiting surface, a plurality of first notches, and a plurality of second notches. The first notches are sunken at the light exiting surface. There is a reflection surface in each of the first notches. The second notches are respectively opposite to the first notches and sunken at the bottom surface. The second notches respectively have a light incident curve-surface. The light-emitting devices are respectively disposed beside the light incident curve-surfaces. Each of the light-emitting devices has a light exiting surface capable of providing a light beam. The light exiting surface is not conformal to the light incident curve-surface. The light diffusion micro-structures are disposed on the bottom surface.
Abstract:
A light source apparatus including a light guide plate, a first light emitting unit, and a second light emitting unit is provided. The light guide plate has a first surface, an opposite second surface, a first side surface, and an opposite second side surface. The first light emitting unit is disposed beside the first side surface for providing a first light beam. The second light emitting unit is disposed beside the second side surface for providing a second light beam. The first light emitting unit has a central line passing through a geometric center of the first light emitting unit and being perpendicular to the first side surface. The second light emitting unit has a central line passing through a geometric center of the second light emitting unit and being perpendicular to the second side surface. The central lines do not coincide with each other.
Abstract:
A measurement apparatus capable of displaying battery power includes a battery cell, a measurement chip and an information display unit. The battery cell stores the battery power. The measurement chip further includes an acquiring unit, a converting unit, a processing unit and a display driving unit. The acquiring unit acquires the battery power from the battery cell to generate a first power signal. The converting unit converts the first power signal into a second power signal. The processing unit analyzes and computes the second power signal to provide battery power information. The display driving unit drives the information display unit. The battery power information can selectively represent the battery power corresponding to the battery cell to a user through the display driving unit.
Abstract:
An image processing method and a related image display system. A video signal with original data items of original dots is received, all the original dots constructing one line of an image. The original data items are processed to perform a zoom function and generate processed data items, which are then written to the memory units of a buffer. Before all the processed data items are written to the memory units, the processed data items stored in the memory units are sequentially read to drive corresponding dots in a line on a display. The time when all the processed data items stored in memory units have been read ends at substantially the same time as that when all the processed data items have been written to memory units.
