Abstract:
This present invention discloses a backlight module including a frame and a light guide plate. The frame includes a base plane and a side wall, wherein the side wall is disposed at the edge of the base plane and encloses a disposition space. The side wall includes a first inner surface and an outer surface, wherein a distance between the first inner surface and the outer surface is decreased as the first inner surface comes closer to a bottom of the side wall. The light guide plate is disposed on the base plane and within the disposition space, wherein the first inner surface sinks toward the outer surface and a recessed space is formed between the first inner surface and a lateral side of the light guide plate.
Abstract:
A mobile device and navigation device communication system utilizing near field communication to easily capture and transfer address data and simplify programming of the navigation device is disclosed. When a mobile device receives a text message a mobile navigation communication application determines if there is an address included in the text message and if found extracts the address and encodes the address. The user then places the mobile device in close proximity to the navigation device and the data exchange is performed via near field communication. After the data exchange is complete the navigation device decodes the data into the address and searches its database to find an address match. The navigation device then displays the address for the user to confirm. After confirmation the navigation device displays the route or driving directs from the user's current location to the destination address.
Abstract:
A RF front-end circuit and a low noise amplifier thereof configured for a receiver are provided. The circuit includes a low noise amplifier and a quadrature passive mixer. The low noise amplifier provides two RF output differential signals to the quadrature passive mixer. The RF signals are down-converted to the differential in-phase baseband signals and the differential quadrature-phase baseband signals. The structure of the RF front-end circuit can avoid the signal and noise interfering between in-phase channel and quadrature-phase channel without using a 25% duty cycle local oscillation generator circuit.

Abstract:
A heat dissipating module disposed between a plurality of heating elements is provided. The heat dissipating module includes a plurality of heat conducting units, a set of heat dissipating fins, a plurality of fans, a plurality of sensing units and a control unit. The heat conducting units are connected to the set of the heat dissipating fins and the heating elements. A gap exists between the heat conducting units. The fans are disposed at the same side of the set of the heat dissipating fins. The sensing units are coupled to the heating elements, respectively, to detect the heat generated by the heating elements. The control unit is electrically connected to the fans and the sensing units. The heat generated by the heating elements is different from each other, and the control unit adjusts the speed of the fans according to the heat generated by the heating elements.

Abstract:
A cutter is provided to cut scrap wire into pieces. The cutter includes a base with a fixed shaft and a floating shaft parallel to the fixed shaft, a resilient connection device supporting the floating shaft, a master gear rotatably mounted on the fixed shaft, and a slave gear rotatably mounted on the floating shaft and engaging the master gear. Teeth of the master gear are pointed and an angle of the teeth of the master gear is less than 60°. A force provided by the resilient connection device is parallel to the center lines of the master gear and the slave gear, and when scrap wire is fed into the cutter, the master gear and the slave gear collectively cut the scrap wire into pieces.
Abstract:
A centrifugal fan includes a spiral housing, a driving mechanism and multiple internally mounted impellers. The driving mechanism and the centrifugal impeller, rotated by the driving mechanism, are installed in the spiral housing. A spiral flow channel is defined between the centrifugal impeller and the spiral housing. When the centrifugal impeller rotates, airflow is sucked axially into the spiral housing through an inlet opening and moves along each blade of the centrifugal impeller into the spiral flow channel. The centrifugal impeller includes a hub and multiple blades. Each blade is secured to the hub at one end and has at least one vertical convex strip or vertical concave strip at an opposite end, wherein the vertical convex strip or vertical concave strip on each of blade disturbs the airflow across thereof and reduces narrow-band noise.
