The present application provides a pressure-sensitive adhesive layer comprising at least first and second regions having different physical properties, wherein the difference in physical properties, such as an elastic modulus or creep strain rate is maintained relatively large for each region, and the difference in physical properties, such as a peel force or recovery rate is maintained relatively small for each region.

A computing system compares various reference fingerprints each representing a reference media stream broadcast on a different respective known channel, and the computing system determines that a plurality of the reference fingerprints match each other, thus defining a multi-match group of the matching reference fingerprints. In response, the computing system identifies a fingerprint feature that could define a distinction between the reference fingerprints, and the computing system resolves the multi-match based on the identified feature, thereby determining the channel carrying the media stream being rendered by the media presentation device. And the computing system could then take channel-specific action based on the determined channel.

A continuous method of manufacturing adhesives is provided. The method includes obtaining an actinic radiation-polymerizable adhesive precursor composition disposed on a major surface of an actinic radiation-transparent substrate and irradiating a first portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a first irradiation dosage. The method further includes moving the actinic radiation-transparent substrate and irradiating a second portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate for a second irradiation dosage. Optionally, the method also includes irradiating a third portion of the actinic radiation-polymerizable adhesive precursor composition through the actinic radiation-transparent substrate prior to moving the substrate. The first irradiation dosage and the third irradiation dosage are often not the same, thereby forming an integral adhesive having a variable thickness in an axis normal to the actinic radiation-transparent substrate.

An adhesive composite is provided that may include a substrate and an adhesive layer overlying the substrate. The adhesive layer may include at least a first region of a high Tg adhesive material and a second region of a low Tg adhesive material. The first region of the adhesive layer may be co-planar with the second region of the adhesive layer. The high Tg adhesive material may include a first glass transition temperature Tg1 and the low Tg adhesive material may include a second glass transition temperature Tg2, where Tg1 is greater than Tg2.

Disclosed herein are methods and systems to help disambiguate channel identification in a scenario where fingerprint data of media content being rendered by a media presentation device matches multiple reference fingerprints corresponding respectively with multiple different channels. Upon detecting such a multi-match, a server or other entity will perform disambiguation based at least in part on a comparison of time of broadcast of the media content being rendered by the media presentation device with time of broadcast of the media content represented by the reference fingerprints. The server or other entity will thereby determine the channel on which the media content being rendered by the media presentation device is arriving, so as to facilitate taking channel-specific action.

A computing system receives from a media presentation device a query fingerprint stream representing media content being presented by the media presentation device, where the query fingerprint stream has been determined to represent a first channel. The computing system then detects that a threshold mismatch exists between the received query fingerprint stream and a reference fingerprint stream representing the first channel, thus indicating a likelihood that the media presentation device has transitioned from presenting the first channel to presenting a second channel. Responsive to detecting the threshold mismatch, the system thus discontinues channel-specific action with respect to the first channel. For instance, the system could discontinue superimposing of first-channel-specific content on the presented media content and perhaps start superimposing of second-channel-specific content instead.

Herein are disclosed a pressure-sensitive adhesive layer on a substrate, the adhesive layer containing stripes of first and second pressure-sensitive adhesives. The surface of the adhesive layer that faces the substrate is surface-enriched with the first pressure-sensitive adhesive. Methods of making are disclosed.

Provided is a PSA sheet with which good air release properties can be obtained while whose quality can be further enhanced. This invention provides a PSA sheet comprising a substrate film and a PSA layer provided to at least one face of the substrate film. The PSA sheet further comprises a coating layer partially covering the PSA layer surface. The PSA sheet's adhesive is formed of the PSA layer and the coating layer. The coating layer has a linearly extending part running from one edge to another edge of the adhesive face. The linearly extending part has a first face forming the PSA sheet's adhesive face and a second face located on the PSA layer side relative to the first face. The second face of the linearly extending part forms an overall gently curved line in a cross section perpendicularly intersecting the length direction of the linearly extending part.
