Abstract: A method of using a catheter assembly for inserting in a fluid filled space in a body includes providing a main body having a first end portion and a second end portion. The first end portion is positioned within the fluid filled space. The second end portion is adjusted to extend outwardly from the fluid filled space when the first end portion is positioned within the fluid filled space. A catheter tip is connected to the second end portion of the main body. The catheter tip includes a housing having a cavity defined therein and a rotating element positioned within the fluid filled space. The rotating element is rotated within the cavity of the housing to impart movement of the first end portion of the main body within the fluid filled space.

Abstract: Techniques for monitoring an online video advertisement system include receiving a request for insertion of an online video advertisement, determining, selectively based on presence of a debug suffix, whether the request includes a debug request, performing a bidding auction to select a winning bid, and sending debug information, in response to the request, upon determination that the request includes the debug request. The debug data includes bid data received during the bidding auction. In one advantageous aspect, the use of hypertext transfer protocol headers to communicate debug information allows for activation and deactivation of the debugging operation transparently, e.g., without changing the underlying application layer workflow.

Abstract: A digital media advertisement delivery system comprising a real time bidding (RTB) platform and a plurality of bidder computers. The RTB platform is configured to receive an indication of an opportunity to display a digital media advertisement to a consumer, and generating a bid request for auctioning the opportunity to a plurality of bidders, the bid request comprising a plurality of fields including information about the opportunity. The plurality of bidder computers are configured to receive the bid request comprising a first plurality of fields including information about the opportunity, decide, based on the received information in the plurality of fields, whether or not to bid, and send a bid response, when decision is to bid, comprising a second plurality of response fields, at least some of which include information in direct response to the first plurality of fields.
