| 20100139479 | VARIABLE COMPRESSION RATIO PISTON WITH RATE-SENSITIVE RESPONSE - A hydraulic variable compression ratio (VCR) piston for use in an internal combustion engine. The piston is a two-part piston, in which a gudgeon pin carrier slides within an outer sleeve. A variable volume upper chamber is formed between the top of the gudgeon pin carrier and the end of the outer sleeve. When the upper chamber fills with oil, its volume increases, and the overall piston geometry is longer. This reduces the piston clearance in the cylinder and increases cylinder pressure. At a given maximum cylinder pressure or at a given rate of increase of cylinder pressure, oil from the upper chamber is relieved by using a rate-sensitive pressure relief valve. | 06-10-2010 |

| 20090178405 | HCCI COMBUSTION TIMING CONTROL WITH DECOUPLED CONTROL OF IN-CYLINDER AIR/EGR MASS AND OXYGEN CONCENTRATION - A method of controlling homogenous charge compression ignition (HCCI) combustion timing and pressure rise rate. A constant volume air pump, such as a supercharger, is equipped to provide a variable amount of fresh air to a turbocharger. The also turbocharger drives a high pressure exhaust gas recirculation (EGR) loop. The fresh air intake and the EGR ratio are independently controlled. This combination of hardware allows for good control of combustion timing by providing for EGR variations without undue effect from varying oxygen concentration. Additionally, by adjusting the EGR ratio, the pressure rise rate during combustion can be controlled to reduce combustion noise. | 07-16-2009 |

| 20090012341 | Dehydrogenation Reactions in Narrow Reaction Chambers and Integrated Reactors - Methods of dehydrogenating hydrocarbons to yield unsaturated compounds are described. Reactor configurations useful for dehydrogenation are also described. Hydrocarbons can dehydrogenationed, for relatively long periods of time-on-stream, in a reaction chamber having a dimension of 2 mm or less to produce H | 01-08-2009 |
| 20100300550 | Multi-Stream Microchannel Device - Provided is a process and device for exchanging heat energy between three or more streams in a microchannel heat exchanger which can be integrated with a microchannel reactor to form an integrated microchannel processing unit. The combining of a plurality of integrated microchannel devices to provide the benefits of large-scale operation is enabled. In particular, the microchannel heat exchanger enables flexible heat transfer between multiple streams and total heat transfer rates of about 1 Watt or more per core unit volume expressed as W/cc. | 12-02-2010 |

| 20110011108 | Microprocessor-Controlled Beverage Dispenser - A microprocessor-controlled beverage dispenser is disclosed, which provides a cold plate having disposed therein beverage lines and refrigerant lines. The refrigerant lines may be connected to a cooling or refrigeration system, including a heat exchanger. The beverage lines may be connected to a beverage supply for dispensing a desired beverage. Valves and pressure sensors in the refrigerant line are engaged with a microprocessor. If the temperature falls below a desired value, then the cooling system is shut off. This permits the microprocessor to closely control the temperature of the beverage being dispensed. | 01-20-2011 |

| 20110289947 | Temperature-controlled beverage dispenser - A temperature-controlled beverage dispenser is disclosed, which provides a cold plate having disposed therein beverage lines and refrigerant lines. The refrigerant lines may be connected to a cooling system, such as a heat exchanger, which is configured to remove heat from the cold plate. The beverage lines may be connected to a beverage supply for dispensing a desired beverage. Valves and a pressure sensor in the refrigerant line are connected to a microprocessor. At regular intervals, the microprocessor closes the valves, waits a short time, and then takes a pressure reading, which corresponds to a temperature. If the temperature falls below a desired value, then the cooling system is shut off. This permits the microprocessor to closely control the temperature of the beverage being dispensed. | 12-01-2011 |

| 20080236006 | Method and apparatus for delivering visual information - An information display device illuminates a light pipe, and includes a controller to regulate the power levels delivered to a light source, thereby regulating the amount of light delivered to the light pipe. Alternatively, the information display device delivers visual data, including alpha-numeric characters, predetermined images, or a controlled phasing. The information display device may be utilized to illuminate information associated with the structure. The illumination system provides the ability to phase between different colors, as well as blended colors. Accordingly, an information display device phases between varying colors, and may blend colors to create color schemes. The illumination system includes a control module disposed within the structure to control device parameters. The illumination system further includes landscape lights that are in communication with the control module and the information display device, such that the landscape lights may phase with the information display device, thereby providing a unified phasing effect. | 10-02-2008 |
| 20090188938 | Apparatus for dispensing flavors in specified quantities - An apparatus for dispensing flavors to beverages or food products is provided. A programmable pump apparatus allows for dispensing a varying amount of a selected flavor in response to user input. A main tower is mountable on countertops or other work surfaces such as a home, office, or food preparation area, and allows users to select one or more flavors and control the amount of flavor dispensed. The apparatus may comprise buttons that can be programmed for pour and hold with a specified time-out and a guard time delay to prevent accidental dispensing of flavor. | 07-30-2009 |
| 20100114365 | Beverage dispenser including an improved electronic control system - A beverage dispenser includes an electronic control system for controlling beverage dispenser components. The beverage dispenser components include at least a user interface, a dispensing valve, and a valve interface for regulating the delivery of a beverage from the dispensing valve. The electronic control system includes a microcontroller for monitoring the user interface and for activating the valve interface responsive to user input, thereby regulating the delivery of a beverage from the dispensing valve. The electronic control system further includes a program memory with firmware configured in a state machine system architecture for controlling the microcontroller. The state machine system architecture supports either a non-preemptive or a preemptive multitasking real time operating system. The firmware includes supervisory control firmware, dispenser tasks firmware, and low level drivers firmware. | 05-06-2010 |
