摘要:
An engine control unit and method of controlling the operation of a gas fuelled internal combustion engine of the kind having a gas injector for injecting gaseous fuel into each cylinder and an inlet manifold through which air flows into each cylinder of the engine, the inlet manifold having a manifold valve to control the flow of air into the inlet manifold. An improved control strategy employed by the engine control unit involves closed loop control of airflow through the inlet manifold of the engine. Manifold absolute pressure (MAP) (70) and manifold air temperature (MAT) (72) are employed to calculate air density (84) which is representative of the mass of air flowing through the inlet manifold (28). The detected air density (84) is compared to a desired air density (DAD) (86) and an air density correction (88) is calculated to adjust the manifold valve position (MVP) (90).

A manifold valve controller (30, 32) designed to be embedded within the casing (24) of a throttle actuator in a manifold valve assembly for a gas fueled internal combustion engine. The controller (30, 32) senses the current position and current velocity of the valve (14) and calculates a rest position of the valve (14) if the valve commenced deceleration from its current position and velocity. The controller (30, 32) then compares the calculated rest position with a demanded position for the manifold valve (14) in order to determine whether the current position or the rest position exceeds the demanded position The controller (30, 32) then accelerates or decelerates the valve (14) to the demanded position as required, based on the comparison A feedback position sensor such as a potentiometer (22) provides the means for sensing the current position and velocity of the valve (14). By locating the controller (30) as close as possible to feedback potentiometer (22) problems caused by background electrical noise are minimized.

Methods, apparatus, and articles of manufacture to identify media delivery are disclosed. An example method includes receiving a first log from a media provider, the first log comprising first source address information, first destination address information, first source port information, first destination port information, and media identification information; receiving a second log from a first receiver, the second log comprising second source address information, second destination address information, second source port information, and second destination port information; comparing information in the first log to information in the second log to attempt to identify a matching entry between the media provider and the receiver; and when a matching entry is identified, storing the media identification information from the first log in association with the receiver.

Methods, apparatus, and articles of manufacture for using location information to manage spillover in an audience monitoring system are disclosed. In particular, the example methods, apparatus, and articles of manufacture detect spillover to generate media monitoring information. Initially, a first sensor located in a first location and a second sensor located in a second location receive a portable metering device signal. First location information is associated with receiving the portable metering device signal via the first sensor and second location information is associated with receiving the portable metering device signal via the second sensor. Media monitoring information is generated based on one of the first location information or the second location information.

Methods and apparatus to extract audio codes are disclosed. An example method includes receiving signals on a plurality of channels and ranking the signals based on at least one characteristic of the signals. A first channel from the plurality of channels is selected based upon the ranking of the signals. The example method further include determining whether a first signal on the first channel includes at least one code and extracting the at least one code from the first signal when the first signal includes the at least one code.
摘要:
Methods and apparatus for detecting a composition of an audience of an information presenting device are disclosed. One disclosed method captures images (18) of the audience, determines (20) a number of people within the images and prompts (24) the audience to identify its members if a change (22) in the number of people in the audience is visually detected. This disclosed method voids both under-sampling of the audience and excessive prompting of the audience by only requesting entry of identification data when an audience change occurs. Methods and apparatus to determine the number of persons in an image or series of images are also disclosed.
摘要:
Systems and methods for determining whether a television is on and in as near proximity are provided. An example system includes a sensor, an analog-to-digital converter, and a digital signal processor. The digital signal processor processes a set of digital audio samples detected by the sensor to determine if the sensor is in near proximity to a television in an on state.

A packaging blank capable of forming a reclosable container comprises in one embodiment a front panel having opposing side panels, a rear panel connected to the front panel by the second side panel, a top panel connected to a top edge of the front panel, a bottom panel connected to a bottom edge of the front panel, and a pour spout flap connected to a top edge of the second side panel. Upon construction the packaging blank provides a reclosable container having an integral pour spout that is releasably securable to a portion of the top panel. Still further, the invention relates to a method of forming the container and a method of packaging articles in the container.
摘要:
A water-hydrogen engine system runs on hydrogen energy of water that is spray-atomized and heated electrically in a hydrogen activator (1) to heat-activate water for releasing hydrogen energy. At elevated temperatures employed, steam is over 95% hydrogen pressure and less than 5% oxygen pressure, although about 89% oxygen by weight. While remaining molecularly associated with oxygen in gaseous H2O hydrogen is heat-distanced from the oxygen. The heat-distanced hydrogen proton nucleus is heat-weakened for allowing hydrogen electrons to be activated exponentially per level of heat added. Hydrogen pressure typically an order of magnitude greater than combustion pressure of known heat engines is directed from the hydrogen activator to a pressure chamber (5) of forms of gas-powered mechanisms. The gas-powered mechanisms include turbocam hydrogen engines (11) for all rotational applications, trans-atmospheric propulsion engines (71) for all propulsion applications and projectile-expulsion engines (78) for most weapon applications. Use of combustion gas and use of working media other than water are optional. Only 5-to-15% of output power of the gas-powered mechanisms is used for activating the hydrogen and for operating subsystems. A Hydrogen Era of free universal hydrogen energy is made possible.
