1681results about How to "Reduce control" patented technology

A flash NAND type EEPROM system with individual ones of an array of charge storage elements, such as floating gates, being capacitively coupled with at least two control gate lines. The control gate lines are preferably positioned between floating gates to be coupled with sidewalls of floating gates. The memory cell coupling ratio is desirably increased, as a result. Both control gate lines on opposite sides of a selected row of floating gates are usually raised to the same voltage while the second control gate lines coupled to unselected rows of floating gates immediately adjacent and on opposite sides of the selected row are kept low. The control gate lines can also be capacitively coupled with the substrate in order to selectively raise its voltage in the region of selected floating gates. The length of the floating gates and the thicknesses of the control gate lines can be made less than the minimum resolution element of the process by forming an etch mask of spacers.

A system and method of maintaining an always-on application client communication is provided. An application programming interface implemented on a device hosting an always-on application client determines if network-based keep-alive functionality exists in a network where the device operates. If network-based keep-alive functionality exists, a network element is instructed to transmit keep-alive messages to the application server on behalf of the device. The network element can be implemented in or as a variety of existing network elements, e.g., as a GPRS gateway serving node or a standalone keep-alive network element. Alternatively, an application server communicatively connected to the always-on application client may query whether network-based keep-alive functionality exists. If network-based keep-alive functionality exists, the application server negotiates with the always-on application client to determine an application-specific mechanism for implementing the network-based keep-alive functionality. When an application server queries for network-based keep-alive functionality, an application programming interface need not be utilized.

An overrunning coupling assembly and a method of controlling the engagement of planar first and second members are provided wherein two sets of opposed engaging struts are applied with one motion of a single control plate or member. The planar first and second members have inside surfaces extending generally normal to a first axis. The assembly includes free-floating, forward keys and free-floating, reverse keys opposed to the forward keys. The forward and reverse keys are movable between a notch-engaging, engaged position and a disengaged position in which the second member is permitted to free-wheel relative to the first member. The planar control member is disposed between the first and second surfaces and is controllably rotatable about the first axis between first and second angular positions relative to the first member.

An apparatus creating a flickering flame effect. The apparatus includes a housing with an interior space with first and second stages. A drive mechanism generates a time varying electromagnetic field extending into the first stage. A first pendulum member is pivotally mounted in the interior space of the first stage and includes first and second magnets on first and second ends, with the first end proximate to the drive mechanism such that the first magnet interacts with the varying electromagnetic field to cause movement of the pendulum member. The apparatus includes a second pendulum member pivotally mounted in the second stage with a magnet on a first end proximate to the second end of the first pendulum member. A flame silhouette element extends from the second pendulum member, and a light source transmits light onto the flame silhouette, which is moving due to the magnetic coupling of the pendulum members.

The invention is directed to polyester processes that utilizes a pipe reactor in the esterification, polycondensation, or both esterification and polycondensation processes. Pipe reactor processes of the present invention have a multitude of advantages over prior art processes including improved heat transfer, volume control, agitation and disengagement functions. The pipe reactor processes and apparatus of the present invention are built and operated at a much lower cost than conventional polyester processes.

One aspect of the invention relates to an exhaust treatment apparatus having an NOx reduction system comprising first and second catalyst beds in series with associated first and second ammonia injectors. The first catalyst bed with its associated ammonia injector preferably targets removing only about 80 to about 95% percent of the NOx in the vehicle exhaust. The second catalyst bed with its associated injector preferably target removing about 70 to about 100% of the remaining NOx. Staging the reduction system in this manner improves control over NOx reduction and reduces the risk of ammonia slip. Other aspects of the invention relate to methods of treating vehicle exhaust to remove NOx and an SCR reactor comprising a housing having an entrance port, an exit port, and an ammonia injection port, wherein the injection port is configured to inject ammonia in between SCR catalyst beds contained in the housing.

The method includes: receiving a first Non Return to Zero (NRZ) data signal and a synchronous clock signal, and performing Return to Zero (RZ) processing to generate a first complementary RZ data signal pair; receiving a second NRZ data signal and a synchronous clock signal, and performing RZ processing to generate a second complementary RZ data signal pair; and modulating the first complementary RZ data signal pair and the second complementary RZ data signal pair on light to generate an RZ-Differential Quadrature Phase Shift Keying (RZ-DQPSK) optical signal. Through the method and device, RZ processing are performed on the NRZ data signals to generate the complementary RZ data signal pairs, and the complementary RZ data signal pairs are modulated on the light, thereby reducing the cost and the insertion loss of the entire device, lowering the requirements for input optical power and reducing the complexity of loop circuit control.

A pouch having a distal edge and a proximal edge. A tear notch is located adjacent to the proximal edge. A first pull ring is defined within an edge panel of the proximal end. The first pull ring enables a user to open the pouch by moving the first pull ring to propagate a tear in the pouch from the tear notch toward the distal edge.

A wind turbine generator, an active damping method thereof, and a windmill tower in which vibrations of the wind turbine generator itself or the windmill tower can be reduced at low cost are provided. The acceleration due to vibrations of a nacelle (13) is detected with an accelerometer (17) attached to the nacelle (13). In an active damping unit (20), a pitch angle of windmill blades (12) for generating a thrust on the windmill blades (12) so as to cancel out the vibrations of the nacelle (13) is calculated on the basis of the acceleration, and the pitch angle is output as a blade-pitch-angle command δθ* for damping. On the other hand, in a pitch-angle control unit (30), a pitch angle of the windmill blades (12) for controlling the output to be a predetermined value is calculated, and the pitch angle is output as a blade-pitch-angle command θ* for output control. The blade-pitch-angle command δθ* for damping is combined with the blade-pitch-angle command θ* for output control using a subtracter (40). The pitch angle of the windmill blades is controlled on the basis of the resulting blade-pitch-angle command after combining.
