Abstract: A nose respirator device with a holder connected to a base. The holder has a top which is configured to sit on nasal bridge and is joined on each side with an arm which extends downward and joins the base which is configured to sit across subnasale underneath nose tip. The base contains two separate open cavities, each open cavity has an upper opening shaped like a cone suitable for insertion into a nostril. Each open cavity of the two separate open cavities can be further divided by a separator into two channels. Valves installed along inside wall of each channel control air flow as the valves are configured to open only in one direction when being pushed by air current. Filters can be fitted into each cavity or each channel within each cavity for air cleaning.

Abstract: A nose respirator device with a holder connected to a base, the holder has a top sitting across the nasal bridge and two arms extending downward to join with the base, which sits across the subnasale and contains two open cavities with upper openings capable of being inserted into each nostril. Each cavity can be further divided by a separator into two channels for inhalation and exhalation, respectively. One-way air flow in each channel can be further ensured with valves, which open only in one direction upon the push of air current. Filters can be fitted into each cavity or channel for air cleaning. One or more attachments can be fitted onto the base for additional purposes, which include extra filtration and disinfection. The area within the holder and the base can be covered with a sheet, which can also be used for device classification and user identification.

Abstract: A method to detect a number of individual users included in a composite set of movie ratings having ratings from a plurality of individual users includes accessing the composite set of movie ratings and movie profiles and loading the composite set and movie profiles into a rating analysis engine. Processing the composite set along with the movie profiles determines a number of partitions present in the composite set, wherein the number of partitions is determined iteratively using subspace clustering of ratings from the composite set. The determined number of partitions is output and corresponds to the number of individual users included in the composite set of movie ratings.

Abstract: A data processing method comprising establishing a first node in a peer-to-peer data communications network, wherein the node is configured as a supernode in conformance with a peer-to-peer communications protocol, wherein the first node is configured as an active listener to one or more network routing protocols executing at a network router; receiving a routing information message from one of the network routing protocols; modifying an operational characteristic of the first node in response to the routing information message; receiving a request from a second node in the peer-to-peer network for a resource that is known to the first node; and responding to the request based on the modified operational characteristic. For example, a peer-to-peer node may be configured as a network-aware BitTorrent Tracker, Gnutella supernode, etc., and can use IGP and BGP information from a router to determine how the node behaves.
