Providing alternative representations of virtual content in a virtual universe
Patent No. 8,972,870
An invention for automatically reducing a load on a server functioning with a virtual universe is provided. In one embodiment, there is an alternative representation tool, including a detection component configured to detect a load on a server, and a determination component configured to determine whether the load on the server exceeds a predefined threshold. The alternative representation tool further comprises a rendering component configured to provide an alternative representation of a virtual content renderable in the virtual universe to reduce the load on the server in the case that the load on the server exceeds the predefined threshold.

Co-flow microfluidic device for polymersome formation
Patent No. 8,968,873
A microfluidic device to produce polymersomes having three coaxial passageways of increasing size with fluid flowing in one direction. The first and smallest passageway contains the content of the polymersome, the middle passageway contains a block copolymer, and the largest and outer passageway contains an aqueous medium or water. The device can produce polymersomes with control of size and membrane thickness. The device will allow quantitative loading of the polymersomes in high quantities. The device is robust and easily assembled and has the ability to independently control the three streams involved in making the polymersomes.

System and method for determining a lubricant discard interval
Patent No. 8,977,421
A system, a method and a computer program to determine the usability of a lubricant such as, e.g., engine oil, and when to replace the lubricant in a particular engine. The system, method, and computer program are further configured to generate a lubricant discard interval for each engine in, e.g., a company’s fleet of vehicles. The system, method, and computer program are configured to generate lubricant discard interval schedule for each of the vehicles in the company’s fleet based on the lubricant discard intervals.

Fuel additive for improved performance in fuel injected engines
Patent No. 8,974,551
The disclosure provides a fuel additive concentrate, a method for cleaning fuel injectors, a method for restoring power to a diesel fuel injected engine, a fuel composition, and a method of operating a fuel injected diesel engine. The additive concentrate includes (a) a hydrocarbyl substituted quaternary ammonium internal salt and (b) a hydrocarbyl substituted dicarboxylic anhydride derivative, wherein the hydrocarbyl substituent has a number average molecular weight ranging from about 450 to about 1500. A weight ratio of (a) to (b) in the additive concentrate ranges from about 1:20 to about 2:1, and the additive concentrate is devoid of a reaction product of a hydrocarbyl substituted dicarboxylic acid, anhydride or ester and an amine compound of the formula ##STR00001## wherein R.sup.2 is hydrogen or a hydrocarbyl group containing from 1 to 15 carbon atoms, and R.sup.3 is hydrogen or a hydrocarbyl group containing from 1 to 20 carbon atoms.

Interspinous implant, tools and methods of implanting
Patent No. 8,974,496
Devices, tools and methods for minimally invasive implantation and distraction between spinous processes for treatment of spinous disorders. An interspinous implant device for distracting at least one pair of adjacent spinous processes includes a main body including a shaft having a longitudinal axis; and first and second arms extending transversely from the main body, wherein at least one of the first and second arms is slidably mounted with respect to the shaft. The arms are configured and dimensioned to extend laterally from both sides of the spinous processes when implanted therebetween and to be inserted between the spinous processes laterally from a single side thereof. The arms are variably positionable between a closed configuration, to facilitate insertion of the arms between the adjacent spinous processes, and an open configuration, in which the arms are separated from one another.
