Title: Wind turbine with inlet cells
Inventor: CHAFE PAUL C
IPC: F03D1/04
Filed: 2003-02-07
Abstract: The present invention is a novel development of the power producing wind turbine in which a plurality of inlet cells are used to channel airflow through a matching venturi to a turbine. The cells are shaped to maximize airflow through the system. The structure may be directional (ie, harvesting wind from a specific sector of the compass) or omnidirectional (harvesting wind from any direction) depending on the specifics of the installation site. The underside of the structure forms a venturi which reduces backpressure on the turbine and enchances throughput of the system. The system geometry is variable to allow it to operate at maximum power over a wide range of wind speeds.

Abstract: A negative pressure respirator (20') that has an integrally-disposed filter element (28) and that covers at least the nose and mouth of a wearer. The respirator (20') includes an exhalation valve (22) and an impactor element (50) that covers the exhalation valve (22). The exhalation valve (22) has a diaphragm and an orifice and opens in response to increased pressure when the wearer exhales to allow exhaled air to be rapidly purged from the mask interior. The impactor element (50) is positioned in the exhale flow stream to remove particles and other contaminants from the exhaled air. The exhalation valve and impactor element have a ratio of Zn:Dj of less than about 5. The respirator (20') is beneficial because it provides comfort to the wearer by allowing warm, moist, high-CO2-content air to be rapidly-evacuated from the mask interior through the valve (22) and also protects the wearer from splash-fluids and from polluted air while at the same time protecting other persons or items from being exposed to particles and other contaminants exhaled by the wearer.

Title: A retrieval system and method based on a similarity and relative diversity
Inventor: SMYTH BARRY JOSEPH
IPC: G06F17/30
Filed: 2002-07-30
Abstract: A data processing method and system for retrieving a subset ofk items from a database ofn items (n » k) firstly determines a limited set ofbk items (b &g t; 1) in the database which have the greatest similarity to an input query t according to a given similarity function S. A result subset is then constructed by including as a first member the item having the greatest similarity S to the query t, and iteratively selecting each successive membe r of the subset as that remaining item of the bk items having the highest quality Q, where Q is a given function ofboth similarity to the input query t and relative diversity RD with respect to the items already in the results subset. In this way the diversity of the results subset is greatly increased relative to a simple selection of the k most similar items to the query t, with only a modest additional increase in processing requirements.
