Abstract:
A light emitting apparatus and a control method thereof are provided. The light emitting apparatus has a semiconductor device capable of emitting light, and the control method includes the following descriptions. A driving power of the semiconductor device is reduced to an ideal power stepwise and gradually. After every time the driving power of the semiconductor device is reduced, the semiconductor device continually emits the light by the reduced driving power within a predetermined time.
Abstract:
A method for adjusting an idle-timeout period of a connection between a wireless communication device and a host includes following steps: detecting a plurality of time intervals of data transmission between the wireless communication device and the host; generating a time-interval variation rate according to the time intervals; and adjusting the idle-timeout period according to the time-interval variation rate.
Abstract:
A security connection establishing method for a wireless device and a wireless host is disclosed. The security connection establishing method includes the steps of allowing the wireless device to generate a trigger signal, allowing the wireless host to receive the trigger signal, allowing the wireless host to generate an accepting signal according to the trigger signal, allowing the wireless device and the wireless host to directly establish a security connection according to the accepting signal, and providing a connection result.
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:
The present invention provides a transmission method for reducing radio resource overhead for a slave device of the Bluetooth system. The transmission method includes the steps of setting an active time slot window on a communication time comprising at least a reception time slot and transforming the reception time slots in the active time slot window into transmission time slots.
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:
An optoelectronic semiconductor package for packaging a heat source capable of emitting light includes a base, a seal member, and a plurality of heat-dissipation elements. The base carries and touches the heat source and has a plurality of openings formed thereon, and the seal member is used to seal the heat source on the base. Each of the heat-dissipation elements is inserted in one of the corresponding openings, and the heat-dissipation element placed in the corresponding opening is deformed to result in a tight coupling between the heat-dissipation element and the base.
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.
