Abstract: An illumination system having a light source, an integration rod and a color wheel is provided. The light source is suitable for providing a light beam. The light integration rod and the color wheel are disposed in the transmission path of the light beam. The color wheel is disposed between the light source and the light integration rod. The light integration rod has a light input end adjacent to the color wheel and a light output end opposite the light input end. The light integration rod has two indentations at the light input end to form an airflow channel. The noise caused by the rotating color wheel is reduced through the airflow channel.

Abstract: An illumination system includes a lamp, an optical element, a fan and a wind-guiding device. The extended direction of the central axis of the fan is slanted to the optic axis of an illumination beam from the lamp with an angle. The wind-guiding device includes a wind-guiding portion and a frame having a first carrying surface for carrying the fan. A second carrying surface of the frame is opposite to the first carrying surface and faces towards the lamp and the optical element. A wind-guiding plate of the wind-guiding portion is extended from a side of the frame towards the optical element and has a bending corner. A part of a cooling airflow from the fan passes through an opening of the frame and is blown to the lamp directly, and another part thereof is guided by the bending corner and is blown directly to the optical element.

Abstract: A wireless audio system includes a first device and a second device. The first device includes a first logic and a first WLAN unit coupled to the first logic. The first logic performs audio processing to generate audio data. The first WLAN unit transmits the audio data through a radio frequency channel. The second device includes a second WLAN unit and an audio reproducing unit coupled to the second WLAN unit. The second WLAN unit receives the audio data from the radio frequency channel. The audio reproducing unit generates sound according to the audio data.

Abstract: A multimedia system includes a data source for providing a multimedia data; a wireless transmitting module, coupled to the data source, comprising a wireless transmitter for transmitting the multimedia data; a wireless receiving module comprising a wireless receiver for receiving the multimedia data from the wireless transmitter; and a reproducing device, coupled to the wireless receiving module, for reproducing the multimedia data received by the wireless receiver.

Abstract: A lamp receptacle assembly includes a receptacle body including first and second body parts having confronting peripheral edges fastened together to define a lamp chamber for receiving a lamp unit therein. The receptacle body is formed with a vent unit for ventilation of the lamp unit. At least one net unit covers the vent unit to prevent the broken pieces from scattering within the projection apparatus.

Abstract: A heat-dissipating device includes a receptacle body having a lateral wall formed with an air vent; a lamp unit including a burner, a reflector covered the burner, a glass plate disposed in front of the reflector, the reflector cooperating with the glass plate to define an air inlet adjacent to the air vent and an air outlet spaced from the air vent; a fan unit mounted on the receptacle body for covering the air vent and for generating airflow to flow into the receptacle body; and a nozzle disposed within the receptacle body between the air vent and the lamp unit for guiding the airflow into the lamp unit.

Abstract: A load balancing method applied in a communication apparatus is disclosed. The method includes assigning an identification code to a first and a second wireless transceivers; establishing a first link between a first transceiver and a station through a first channel according to the identification code; and establishing a second link between a second transceiver and the station through a second channel according to the identification code; and replacing the first link by the second link when a load of the first wireless transceiver is greater than that of the second wireless transceiver.

Abstract: An apparatus for improving the management of data packets received from a network comprises a receiver for receiving data packets, a first storage unit for storing data packets, a counter for storing a count value, a second storage unit for storing a threshold value, and a comparator for comparing the count value against the threshold value wherein when count value reaches the threshold value, the apparatus issues a first event. A method for improving the management of data packets received from a network comprises receiving a data packet from the network, transferring the data packet into at least one data buffer, monitoring the number of unavailable descriptors, comparing the number of unavailable descriptors with a threshold value, and triggering a first event when the count value reaches the threshold value.

Abstract: A method and an apparatus for decrypting encrypted data transmitted wirelessly by updating a key-table comprises a receiver in wireless communication with a sender. The method includes receiving an encrypted data from the sender; searching a key-table of the receiver for a decryption key corresponding to the encrypted data; if the decryption key is not stored in the key-table, driving the receiver for searching a master list of the receiver for the decryption key and transferring the decryption key from the master list to the key-table to update the key-table; and decrypting the encrypted data through utilizing the decryption key stored in the key-table. The method also includes the option of disabling the sending of an acknowledgement message from the receiver to the sender after having received data from the sender.
