Tracking and reusing function results
Embodiments for tracking stored function results are described. Results of function executions can be stored so that when the function is invoked again with the same arguments, the stored results can be used instead of re-executing the function. However, using a stored function result, instead of re-executing the function, can only be done safely when data sources used in the function execution have not changed since a previous function execution of the current function invocation. The function result tracking system disclosed herein can correlate, with function executions, one or more timeframes for which results of that function execution are valid. For example, each node referenced in a trace can represent a function execution and each node can be associated with a data structure that keeps track of results of function executions, and timeframes for when those results are valid or invalid. |

Mechanism to free up the overlay of a file-based write filter
An overlay of a file-based write filter can be freed up to thereby minimize the likelihood that the overlay will become full and force a system reboot. An overlay-managing write filter can be employed in conjunction with the file-based write filter to monitor files that are stored in the overlay and move files that are not currently being accessed. If a request is made to access a moved file, the overlay-managing write filter can modify the request so that it targets the location of the moved file rather than the location of the original file on the protected volume. In this way, the fact that modified files are being moved from the overlay but not discarded can be hidden from the file-based write filter. As a result, the effective size of the overlay will be increased while still allowing the file-based write filter to function in a normal fashion. |

Push-based piggyback system for source-driven logical replication in a storage environment
The disclosed techniques enable push-based piggybacking of a source-driven logical replication system. Logical replication of a data set (e.g., a snapshot) from a source node to a destination node can be achieved from a source-driven system while preserving the effects of storage efficiency operations (deduplication) applied at the source node. However, if missing data extents are detected at the destination, the destination has an extent pulling problem as the destination may not have knowledge of the physical layout on the source-side and/or mechanisms for requesting extents. The techniques overcome the extent pulling problem in a source-driven replication system by introducing specific protocols for obtaining missing extents within an existing replication environment by piggybacking data pushes from the source. |

Geometrically multiplexed RGB lasers in a scanning MEMS display system for HMDS
Systems and methods are utilized for performing geometric multiplexing in MEMS display systems that utilize RGB laser diodes and MEMS mirrors to compensate for angular separation between the RGB light that results from passing the RGB light emitted from the RGB laser diodes through a single collimating lens shared by the RGB laser diodes, as opposed to utilizing a separate collimating lens for each corresponding laser diode. Spatial offsets between the RGB light at the target display, resulting from the angular separation, are compensated for by applying temporal buffers to the pulsing of the RGB laser sources so that the RGB light is horizontally and vertically aligned at the appropriate pixels of the target display during scanning by the MEMS mirrors system. |

Faulty load detection for multi-phase electric motor
An electric motor is electrically commutated with the aid of circuitry, in which the phase current experiences a zero crossing at certain time points per motor phase. Owing to the inductive load portion, the time of said zero crossing of a phase current occurs at different times to the time of the zero crossing that would arise with purely ohmic loads. Without a faulty load condition, the time of said zero crossing is within an expected value range (e.g., expected time window) which can be determined by the circuitry, the ambient conditions and by diverse motor parameters. During occurrence of the a high-side and/or low-side phase connection, it is determined whether and when the current through the switched-on high-side of low-side switch becomes greater or smaller than a predeterminable threshold wherein said time measurement can extend over one or more PWM cycles. |

Graphene foam based optical sensor for oil exploration and spills detection
Oil spill detection is crucial, both from an environmental perspective and the associated economic losses. Current optical oil sensing techniques, such as underwater microscopy and light scattering methods, mainly focus on detecting the properties of particles or organisms in water and often require costly equipment and sophisticated data processing. Recent studies on graphitic foam show its extraordinary pollutant absorbing properties, with high absorption weight ratios. Here we propose to produce a graphene foam based ultra-light material that changes its optical properties on absorbing oil species. The results demonstrate clear changes in optical transmission and scattering properties of graphene foam when exposed to various oils. The effective graphene foam sorbent can be easily integrated with optic fibers systems to detect the optical property variations and also to monitor oil presence/spillages remotely. Such sensors can also be used for underground oil exploration. |

Spatial environmental control unit
The goal of the Spatial Environmental Control Unit as a continuation based on the Multifunctional Environmental Control Unit is to create a user friendly accurate analysis and control of heat transfer dynamics in a spatial area that is responsive to the thermal dynamics of the area of interest and accurate to maintain an acceptable level of thermal control as environmental and human biological conditions change without requiring excessive interruptions to the user for manual adjustment. The Spatial Environmental Control Unit (SECU) makes the current norm of an “absolute” temperature control approach for thermal control and human comfort obsolete. A COMFORT “theory of relativity” will now be the new norm. The proposed dynamic process of mapping and analyzing the thermal changes rapidly within the area of interest responds to the unpredictable thermal changes in environment better than the best static or “learning” process currently available. Even though the current “learning” process for thermal control makes periodic changes based on logged user preferences as a function of time, it still controls for extended time, periods with a single static temperature set point. Basically, a series of a series of static control sequences as a function of time. The proposed Spatial Environmental Control Unit incorporates the dynamics of analyzing real time thermal changes with timely feedback from the user. |
