A diffuser assembly is disclosed in which a plurality of baffles having baffle walls with baffle ears extending from selected baffle walls are part of the diffuser core. Adjacent baffle walls define a gap therebetween through which air from an air distribution system is forced to flow and to impinge the baffle ears. The baffle walls, baffle ears, and gaps provide for effective mixing of the air from the air distribution system with ambient air.

A goggle, for use, for example, in paintball, comprises a lens 12, a body structure 14 for the lens and a strap 16. The body structure defines an ocular chamber 34 that covers the wearer's eyes, and an exhalation chamber 36 that covers the wearer's nose and mouth. An inlet plenum channel 42 leads from an inlet chamber 44 in the front of the goggle 10 up to the lower edge of the lens 12, and a fan 46 in the plenum channel 42 blows air from the inlet upwards across the inner surface of the lens 12. Air exhaled by the wearer leaves the exhalation chamber through outlet apertures 56 in the bottom of the mask, and is therefore directed away from the duct inlet chamber 44.

A transform is applied to a region of a current video frame to generate transform signals corresponding to the region. An activity measure is generated using the transform signals. The activity measure is then used to determine whether to encode the region as a skipped region. The region is encoded in accordance with that determination to generate an encoded bit stream for the region. In a preferred embodiment, the transform signals are DCT coefficients and the activity measure is a weighted sum of the DCT coefficients, where the weighting of the low-frequency DCT coefficients is greater than the weighting of the high-frequency DCT coefficients. The region is encoded as a skipped region if the activity measure is less than a threshold value; otherwise, the region is encoded as either an inter encoded region or an intra encoded region.

Enhanced browser caching is provided through a file identifier attribute employed at a front end server level for deterministic marking A front end server may use an attribute of a file identifier such as an attached parameter, a pattern, a directory associated with the file, or similar attributes to change the links it emits into other content in order to prompt the browsers to request new files. The attribute may be changed (e.g. incremented) based on a web change associated with the content being served.

Methods of operation of an access point are disclosed. These methods may involve authenticating a user equipment device in the access point. Access points configured for operating in accordance with the methods are also disclosed. Additionally, methods of operation of user equipment devices, and user equipment devices themselves configured for operating, in conjunction with the access points are disclosed. Still further, core network nodes configured to operate with the access points are disclosed.

A rights-managed document has protected content from an author thereof, whereby a recipient of the document can render the protected content with a corresponding license if the recipient satisfies terms set forth in the license. In the document, a storage portion has a message that the document is rights management protected, and a custom data portion has a section including the protected content. The recipient if enabled can render the protected content in the custom data portion and if not enabled can only review the storage portion having the message. An enabled recipient handles the received rights-managed document by recognizing that the document has the protected content in the custom data portion thereof, and discounting the storage portion of the document. Thus, the recipient examines the custom data portion of the document and proceeds based thereon to render the protected content in the custom data portion.

A system for controlling a roller shade having a roller tube windingly receiving a shade fabric varies roller tube rotational speed for constant linear shade speed. The desired linear shade speed, roller tube diameter and shade fabric thickness and length are stored in a memory for use by a microprocessor. Preferably, the roller tube rotational speed is varied by the microprocessor depending on shade position determined by signals from Hall effect sensors. The microprocessor maintains a counter number that is increased or decreased depending on direction of rotation. Based on the counter number, the microprocessor determines shade position and a corrected rotational speed for the desired linear shade speed. Preferably, the microprocessor controls roller tube rotational speed using a pulse width modulated signal. The system may be used to control first and second roller shades having roller tubes of differing diameters or shade fabrics of varying thicknesses.

A wheel lift-assist frame comprises a pair of support beams, which may be coupled with a tillage machine at first ends, each beam to the left or right of the center of the tillage machine respective and running rearward of the tillage machine. The support beams may also be coupled with a planter. A cross beam is coupled with the support beams at second ends thereof. A plurality of wheel assemblies are fixed to the cross beam at points such that the wheels run between rows created by the tillage machine.
