In some embodiments, a system includes a power system coupled to a power bus, and a power line communication (PLC) gateway coupled in series with the power bus. In other embodiments, a system includes first and second power circuits coupled in series with a power bus, and first and second power-line communication circuits coupled in series with the power bus. In additional embodiments, a system includes a power converter coupled to a power bus and having one or more switching frequencies, and a power-line communication circuit coupled to the power bus and having one or more communication frequencies, where at least one of the switching frequencies is substantially greater than at least one of the communication frequencies.

Power-line communication coupling

A method and apparatus is provided in which a digital image is transmitted to a presentation projector resource over a wireless transmission medium using a reduced amount of bandwidth by transmitting a subset of the digital image data. The subset of image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. The subset image data may also be a scalable vector graphics representation of the subset of the digital image. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received.

Method and apparatus for wireless image transmission to a projector

An apparatus comprises a plug to couple the apparatus to a display device, a first receptacle to receive a first media device containing image data for display on the display device and an imaging processor coupled to the plug and the first receptacle.

The subset image data may be a delta subset that represents those areas of the image that have changed since the previous transmission. Header data is provided to further describe the subset image data. A projector discovery logic selects a suitable projector resource based on the order or signal strength of the discovery replies. A wireless image transmission session is established with the selected projector resource during which the projector is unavailable to other devices. The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received.

The subset image data may be compressed and transmission coordinated with the projector resource so that the data is sent only when it is ready to be received. A wireless to digital visual interface (DVI) graphics engine decompresses and renders the image for output to a DVI connector receptacle. The rendered image is projected by the projector resource in accordance with the associated header data so that the exact image that appears on the image generation device also appears on the projected display.

In a computing device configured to be connected to a wireless network, a method of projecting an image via a projection device over the wireless network, is provided, wherein the projection device is connected to the wireless network via an image-rendering device configured to receive data over the wireless network. The method includes detecting the image-rendering device over the wireless network, presenting a display identifying the image-rendering device to a user, receiving selection of the image-rendering device by the user and sending data representing the image from the computing device to the image-rendering device over the wireless network for projection by the projection device.

Image-rendering device

An apparatus comprises a first plug to couple the apparatus to a host connection and a second plug to couple the apparatus to a display connection. The apparatus further comprises a metallic transmission medium coupled to the first plug and link extender circuitry coupled to the metallic transmission medium and the second plug. The link extender circuitry including equalization circuitry coupled to the metallic transmission medium to restore voltage levels on signals transmitted on the metallic transmission medium, differential signaling receive circuitry coupled to the equalization circuitry; and differential signaling transmit circuitry coupled to the differential signaling receive circuitry and the second plug.

An image-rendering device including a body, a connector configured to removably attach the body to a projection device, the connector movably coupled to the body such that the body is movable between at least a first position and a second position relative to the connector. The image-rendering device further includes an image receiver associated with the body, wherein the image receiver is configured to allow transfer of data representing an image to the image-rendering device. In some embodiments, the image receiver is a wireless receiver. The wireless receiver may be an integrated wireless network card or a removable wireless network card.

The present invention provides an image-rendering device for an image projector. The image-rendering device includes a body having an image receiver adapted to alternatively receive a first interchangeable data transfer device and a second interchangeable data transfer device. Each interchangeable data transfer device is adapted to enable transfer of an image to the image-rendering device. The body may further include a projector connector adapted to operably couple the image-rendering device to the image projector and a processor configured to automatically transmit the image from the image receiver to the image projector for display. In some embodiments, the image-rendering device includes a peripheral device connector configured to enable at least one peripheral device to be operably linked to the image-rendering device. The peripheral device connector may be configured to transmit an image from the at least one peripheral device to the image projector, or vice versa.

An image-rendering device including a body, a connector movably coupled to the body, wherein the connector is configured to electrically and structurally couple the body to the projection device such that the body is movable relative to the connector, and an image receiver associated with the body is provided. The image receiver is adapted to alternatively receive first and second interchangeable data transfer devices, wherein each interchangeable data transfer device is configured to allow transfer of data representing an image to the image-rendering device. The image-rendering device also includes a processor and memory, wherein the memory includes a set of instructions executable by the processor to render the image from the data and to provide the image to the projection device.
