摘要:
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.

A protective guard for a clamping device includes structure for physically separating an end of a band portion of the clamping device from an object or body part that may come in contact with the end. The protective guard can include one or more moveable or statically positioned tabs for inhibiting contact of an object or body part with the end.
摘要:
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.

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.

The secure management of encryption keys is obtained by preventing external access thereto and ensuring that the keys do not leave an encryption unit in their original form. This result is obtained via a facility which (a) generates a unique device encryption key and at least one program encryption key, (b) encrypts the program encryption key using the device encryption key, and (c) stores the result in local memory. Thereafter, responsive to receipt of an indication to encrypt data, the program encryption key is retrieved from memory and is decrypted using the unique device encryption key. The data is then encrypted using the decrypted program encryption key and the encrypted data is stored in a server for distribution to a user who enters a request for the data. When there is a need to transport the latter key to another element, then the program key is encrypted using a symmetrical encryption key that the facility shares with the other element and the result is supplied to that element. The element then decrypts the encrypted program key using its own version of the symmetrical key.
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).
