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

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 transmission bandwidth by transmitting a subset of the digital image data. 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.

Projected systems () include light source apparatuses () for programming narrow bands of unpolarized blue, green, and red light to associated reflective imaging devices that reflect selected patterns of the blue, green, and red light into a dichroic cross-combiner assembly (), which recombines the light into a composite image and directs it into a projection lens () The reflective imaging devices are preferably micromirror displays () having an array of pivotable micromirrors () that direct on-state micromirror light to the projection lens and direct off-state micromirror light to a light absorbing surface ().

System and method employing reflective imaging devices for a projection display

A method and apparatus for a collaborative meeting room system. In response to user input, an electronic device starts a meeting timer to begin timing a meeting at which a previously-created meeting agenda is used. The electronic device causes a projection device to project a running meeting timer, as a result of starting the meeting timer. An agenda item included in the previously-created meeting agenda is retrieved, as a result of starting the meeting timer. The electronic device causes the projection device to project meeting minutes for the agenda item, as a result of retrieving the agenda item.

A patient monitoring system which includes a portable device and a central station. The portable device includes an ECG and a photo-plethysmograph connected to the patient; arrhythmia analysis apparatus; an expert system for determining if a pre-established critical parameter set has been exceeded; and a wireless wide area communication device for automatically contacting the central station via a public cellular phone network when the critical parameter set has been exceeded. When the central station is contacted, the patient's ECG waveforms, measurements, and trends, are sent to the central monitoring station and a two way voice channel between the patient and the central station is automatically opened. The central station includes a computerized facility which has a station from which a clinician can observe the real time data being sent from the patient, the patients historical records and from which the clinician can talk to the patient and activate therapeutic devices attached to the patient such as an external defibrillator, a pacer or an automatic drug infusion device.
