Abstract: The invention relates to a telepresence system comprising a plurality of cameras, a head mounted display device, a processing system and a first orientation sensor, wherein the cameras are positioned at different viewpoints that are aligned so that each camera's field of view at least partly overlaps with those of an adjacent camera, wherein the processing system is arranged to receive image data from each one of the plurality of cameras, to receive orientation information from the orientation sensor, to select one or two cameras, the selection of the one or two cameras depending on the received orientation information, to send image data received from currently selected cameras to the head mounted display device, and if newly received orientation information indicates an orientation change across a predefined threshold, switch from the currently selected cameras to one or two newly selected cameras located at other viewpoints.

Abstract: An externally rigid to semi-rigid wearable computer case for housing various computer components may include two different types of external sides: ventilated-sides and a non-ventilated side. In some embodiments, the wearable computer case may have four to five ventilated-sides. The ventilated-sides and the non-ventilated side together may form an enclosure for housing the various computer components. The ventilated-sides may include ventilation-holes. The ventilation-holes in a given ventilated-side may provide for a ratio of void space to non-void space (in terms of external surface area) that may be substantially from and including 0.6 to 0.4. Some embodiments may also provide for hot swap battery pack(s) that may be external to the wearable computer case and that may provide at least some electrical power to the various computer components housed within the wearable computer case. The wearable computer case and/or the hot swap battery pack(s) may be for VR/AR/MR use.

Abstract: A mobile communication device includes a main wireless transceiver unit for sending and receiving wireless signals, an additional wireless transceiver unit for sending and receiving wireless signals, a motion detection unit, connected to a processing unit and arranged to send a motion signal to a processing unit, and the processing unit, arranged to receive the motion signal and to determine therefrom a parameter representative of a velocity of the mobile communication device, wherein the processing unit is arranged and constructed to turn on the additional wireless transceiver unit when the parameter exceeds a first threshold value. Furthermore, the processing unit is arranged and constructed to turn off the additional wireless transceiver unit when the parameter representative of a velocity remains below a second threshold value for a predetermined period of time.
