Abstract: A transducer fixation apparatus is configured to position and secure to a skin surface of a patient a transducer to allow repeated or continuous monitoring of blood flow in a subsurface vessel. The transducer fixation apparatus includes a housing having a plurality of flexible attachment wings that attach and conform in shape to the skin surface using an adhesive material present on each of the wing undersides. In some embodiments the wings may be biased upward away from the skin surface to facilitate positioning of the fixation apparatus prior to skin attachment. Alternative embodiments include a detachable retainer clip to hold the wings away from the mounting surface during placement as well as an optional positioning wand to aid with placement.

Abstract: A media channel can include a mix of media items and invitational content packages. At some point during the playback of the media channel, an invitational content package can be presented. In response to detecting the occurrence of an interactive segment triggering event during the presentation of the invitational content package, an invitational content interactive segment and a next media item can be simultaneously presented. This can be accomplished by splitting the media channel into multiple streams, such as an audio stream and a visual stream, and presenting an element of the interactive segment within a first stream and an element of the media item within a second stream. To decrease the likelihood that a user may equate the invitational content with the media item, a bumper content item, such as audio that says, “now back to the music,” can be presented just prior to playback of the media item.

Abstract: A compact dual diversity antenna for RF data and wireless communication devices having a printed circuit board is disclosed. First and second PIFAs are mounted on the PCB in a spaced relationship. Each of the first and second PIFAs include radiating elements having ground planes and shorting posts. The ground plane of the second PIFA is disposed in the same plane as the PCB. The ground plane of the first PIFA is orthogonally disposed with respect to the ground plane of the second PIFA. First and second feed posts connect the first and second PIFAs to the PCB through RF feed lines. The first and second feed posts are disposed perpendicularly to one another.
