Abstract: A projection apparatus including a projection module, a projection lens, an actuator, a distance sensor and a controller is provided. The projection module is adapted to project an image beam onto a projection surface to generate a projection image. The projection lens is disposed on a transmission path of the image beam. The actuator is connected to the projection lens and configured to adjust a focal length of the projection lens. The distance sensor is configured to sense a projection distance between the projection apparatus and the projection surface. The controller is electrically connected to the projection module, the actuator and the distance sensor, and is configured to adjust the focal length of the projection lens according to a look-up table and the projection distance sensed by the distance sensor, so as to perform automatic focusing. The lookup table includes a plurality of focal-length segments. The focal length falls within one of the focal-length segments. After confirming an end of a focus adjustment phase, the controller updates a minimum value and a maximum value of the one of the focal-length segments. An auto-focus method is also provided.

Abstract: A transmitter device adapted to be coupled to an image providing device and a receiver device includes first and second conversion units, a wireless module, and a processing unit. The first conversion unit and the second conversion unit are configured to be coupled to the image providing device through an HDMI transmission cable and a Type-C transmission cable, respectively, so as to respectively receive a first video and audio stream and a second video and audio stream provided by the image providing device. The wireless module is connected to the receiver device through wireless communication. The processing unit preferentially selects the first conversion unit to receive a first video and audio signal output by converting the first video and audio stream by the first conversion unit and transmits the first video and audio signal to the receiver device through the wireless module.

Abstract: A conference system with low standby power consumption includes a transmitter, an image data source, a receiver, and a display device. The transmitter includes a battery for providing power, at least one link port for accessing data, and a processor coupled to the battery and the at least one link port. The image data source is used for transmitting the image data to the transmitter. The receiver is linked to the transmitter for receiving the image data. The display device is linked to the receiver for displaying the image data. When the transmitter and the image data source are electrically coupled, the processor ceases to use the battery of the transmitter and controls the image data source for providing power to the transmitter. When the transmitter and the image data source are separated, the processor uses the battery of the transmitter for driving firmware of the transmitter.

Abstract: After a data link between a communication device and a transmitter is established, the transmitter is controlled for determining whether the data link between the transmitter and the communication device is to be disabled when the transmitter is prepared to transmit a first signal to the communication device, or the receiver is prepared to transmit a second signal to the communication device through the transmitter. When the data link is disabled, no signal transmitted from the transmitter is received by the communication device. The first signal and the second signal include feedback control signal information or non-control signal information.
