A Holocam Orb system uses multiple Holocam Orbs (Orbs) within a real-life environment to generate an artificial reality representation of the real-life environment in real time. Each Orb is an electronic and software unit that includes a local logic module, a local CPU and multiple synchronous and asynchronous sensors, include stereo cameras, time-of-flight sensors, inertial measurement units and a microphone array. Each Orb synchronizes itself to a common master clock, and packages its asynchrony data into data bundles whose timings are matched to frame timing of synchronous sensors, and all gathered data bundles and data frames are given a time stamp using a reference clock common to all Orbs. The overlapping sensor data from all the Orbs is combined to create the artificial reality representation.

A computer system includes an operator input device, a central processing unit (CPU), and a display device, such as a liquid crystal display (LCD) or cathode ray tube (CRT) providing a visible image to the computer user as an output of computer activity. The computer system includes a video display controller (VDC) with a graphics generator. This VDC receives image information, such as text or graphics generated by the CPU, or retrieved by the CPU from another facility (such as a CD-ROM) of the computer system, and responsively provides image signals driving the CRT or LCD display. The VDC includes a power saving controller implementing one of several available power saving modes dependent upon one or more of several possible inputs. Each of the power saving modes includes the same list of VDC functions which may individually be enabled or disabled in each power saving mode dependent upon a bit value entered into a register of the power saving controller. Each of the power saving modes is ranked with the others in an order of succession. Accordingly, when each mode of power saving is enabled, it disables the lower-ranked modes of power saving. In turn, each mode of power saving is disabled and succeeded if a higher-ranked mode is enabled.
