Abstract: A distributed storage system includes a primary storage system and a secondary storage system. The secondary storage system stores the actual data and the primary storage system stores metadata for the actual data. The metadata references at the primary storage system may be deleted without deleting the corresponding data at the secondary storage system. Snapshots of the metadata at the primary storage system are sent to the secondary storage system. The secondary storage system can compare two metadata snapshots received from the primary storage in order to determine whether data stored at the secondary storage system has been deleted at the primary storage system for longer than a retention period. Such data may be deleted to free up storage space at the secondary storage server.

Abstract: A multi-rate, burst-mode, photon-counting receiver can communicate at data rates up to 10.416 Mb/s over a 30-foot water channel. With added attenuation, the maximum link loss is 97.1 dB at ?=517 nm. In clear ocean water, this equates to link distances up to 148 meters. For ?=470 nm, the achievable link distance in clear ocean water is 450 meters. The receiver incorporates soft-decision forward error correction (FEC) that supports multiple code rates to achieve error-free performance. A burst-mode receiver architecture provides robust performance with respect to unpredictable channel obstructions. The receiver can detect the data rate on-the-fly and adapts to changing levels of signal and background light. The receiver updates its phase alignment and channel estimates every frame, allowing for rapid changes in water quality as well as motion between transmitter and receiver.

Abstract: A method for preventing image retention in an electronic display, and an electronic display configured to perform such a method. A time period and a pixel threshold may be defined. A checksum calculation of all pixel data within an active image area of the electronic display is preferably performed during the predetermined period of time. A checksum calculation is then performed to determine if the change in pixel data during the period of time is less than the pixel threshold. If not, an image retention prevention procedure is conducted for each area of the active image area of the display where the threshold value was not met. Generally, the image retention prevention procedure includes transmitting alternate pixel data to at least a portion of the pixels within the subject area.

Abstract: A system and method for preventing image retention in an electronic display. A time threshold (TT) and a pixel threshold (PT) may be defined. The system preferably performs a checksum calculation of all pixel data within an active image area of the electronic display for an interval of time until reaching TT. The system may then compare the checksum calculation for each interval of time to determine if the change in pixel data is less than PT. Preferably, the system will perform an image retention prevention method for the active image area if the change in pixel data is less than PT. Generally, this is performed by transmitting alternate pixel data to the electronic display.

Abstract: A display module having electromagnetic interference shielding is disclosed. The display module has a mask circuit board disposed immediately above a first circuit board. One or more light emitting elements are disposed on a top surface of the first circuit board. The mask circuit board has one or more apertures which enable the light from the light emitting elements to radiate outward. The mask circuit board has one or more metalized layers electrically connected to ground which receive and reduces the electromagnetic radiation emitted from the first circuit board. The display module employs one or more shield strips disposed near the perimeter of the mask circuit board and first circuit board to receive and reduce the electromagnetic radiation which would otherwise radiate laterally from the circuit boards.

Abstract: A system maintains a database of scores of job candidates or persons employed in a particular job or occupation. The scores are calculated from responses by the job candidates or the employed persons to inquiries about a display of a three dimensional graphical figure on a true three dimensional display device. The three dimensional graphical figure is displayed on the true three dimensional display device. The display of the three dimensional graphical figure is part of an assessment of a potential job candidate. The system presents an inquiry to the potential job candidate relating to the true three dimensional graphical figure, and receives a response to the inquiry from the potential job candidate. The system calculates a score for the potential job candidate based on the response of the potential job candidate.
