Abstract: An internal combustion engine and a method of controlling an internal combustion engine are provided, that are more efficient than existing engines. The internal combustion engine includes a combustion chamber, and the engine is configurable to operate in: a compressionless operating mode where the engine is driven by combustion of fuel and oxidant in the combustion chamber without compression of the fuel and oxidant; and a compression generating operating mode where the engine is used to compress fluid in the combustion chamber.

Abstract: A backup computer storage system that protects and/or recovers data on a primary computer storage system is disclosed. The backup computer system may be used to backup databases, files, and/or applications. In some embodiments, the backup system may be used to backup an image of the primary computer storage system. In other embodiments, the backup system may be used to backup one or more databases, replicate an image of data that is on the primary computer storage system, restore data from the backup system to the primary computer storage system, restore data to a database while non-affected portions of the database are available and can be used, record all transactions in real time without overwriting any previously stored backup data, and maintain historical and/or chronological information related to backed up data.

Abstract: Methods and apparatuses for verifying a concurrent logical design and a corresponding non-sequential algorithmic description are provided. In some implementations, verification of a non-sequential algorithmic description for a device design is facilitated by monitoring a simulation of the non-sequential algorithmic description and synchronizing the timing of selected events with timing from an already completed simulation of a corresponding logical design. With various implementations, the hierarchical blocks in the logical design are monitored during the prior simulation to record selected event information. Subsequently, the recorded event information may be used to synchronize the simulation of the non-sequential algorithmic description.

Abstract: The present invention provides a wet/dry vacuum cleaner, or a kit for modifying an existing wet/dry vacuum, that includes a hose that is connected to a lower portion of the vacuum such that a pulling force applied to the hose will be applied to the lower portion of the vacuum, thereby preventing the vacuum from tipping over as the unit is pulled around an area using the hose.

Abstract: A multispectral laser camera made up of a plurality of energy producing means which scan a target area. The resultant reflected light off the target produces a true color image of the target after being processed through a series of photomultiplier tubes, amplifiers and modulators. By selectively varying the connections between the above elements a false color image of the scanned target may also be produced. This false color image overcomes the difficulties in detecting camouflaged targets.
