Abstract: A projection device includes a casing, a projection lens, and a fan. The casing includes a main body, a first base, and a second base, wherein the main body has a first side, a second side opposite to the first side, a middle section located between the first side and the second side, air inlet holes at least distributed in the middle section, and air outlet holes at least distributed in the middle section. The first base is installed on the first side, and the second base is installed on the second side. A minimum outer dimension of the main body falls in the middle section, and the air inlet holes face away from the air outlet holes. The projection lens is installed on the main body and located at the same side as the air outlet holes. The fan is installed in the main body.

Abstract: A high-voltage circuitry device is provided. The high-voltage circuitry device includes a high-voltage transistor, a protection component and a feedback component. The high-voltage transistor has a gate, a drain and a source. The protection component is coupled between the source of the high-voltage transistor and the ground. When a current corresponding to an electrostatic discharge (ESD) event flows through the drain of the high-voltage transistor, the current flows from the drain of the high-voltage transistor to the ground through the high-voltage transistor and the protection component. The feedback component is coupled between the protection component, the ground and the gate of the high-voltage transistor. When the ESD event occurs, the feedback component enables the high-voltage transistor to stay on a turned-on state to pass the current.

Abstract: A system for analyzing a sentence emotion is provided. The system comprises a case repository, an input module, a sentence structure analyzing module, a similarity analyzing module and an emotion detection module. The case repository stores several case sentences and each case sentence comprises at least one major term and is corresponding to at least one emotion annotation. The input module receives an input sentence and the sentence structure analyzing module analyzes a sentence structure of the input sentence. The similarity analyzing module performs a semantic analysis and a syntax analysis according to the sentence structure to obtain a similarity level between the input sentence and each of the case sentences. The emotion detection module detects at least one emotion of the input sentence according to the similarity level between the input sentence and each of the case sentences.

Abstract: A protein skimmer for filtering and cleaning water in an aquarium having a foam generating assembly having an air chamber (73) and a nozzle (74) in the air chamber, the nozzle being provided with a plurality of air holes (741) and being connected to an inlet tube (71), the inlet tube communicating with a foam cavity within a vertical guide tube (20) for foam, the guide tube (20) generally being tapered as a whole and including an open upper end (202), a bottom end (203) and a hollow cone-shaped circumferential wall being formed between the upper end and the bottom end and encircling the foam cavity (21) thereby tapering toward and communicating with the upper end (202).

Abstract: The present invention relates to an adapter, more particularly, to an improvement to an adapter for mobile phone. The adapter generally comprises an adapter housing, a conducting wires, and a microphone housing. The adapter is further provided with speaker and amplifying circuits. The microphone housing includes a housing and a terminal socket which includes a multi-pin terminals for electrical connection with the signal socket of the mobile phone. When the plug of the adapter housing is inserted into the lighter-socket and the multi-pin terminal is connected with a mobile phone, the mobile phone is powered by the lighter-socket via conducting wires. The driver may readily use the mobile phone through the microphone without holding the handset. Characterized in that the fixture of the microphone housing includes a bottom housing and a fixing housing. The bottom housing is provided with a groove having a holding socket thereof.
