Title: Progressive relaxation of search criteria
Inventor: DIXON PAUL
IPC: G06F17/30
Filed: 2004-03-31
Abstract: An information search mechanism provides control over the relaxation of search queries to users that are requesting searches. Through this mechanism, users can specify a sequence of sub-queries that is associated with variations of the main search criteria, and specify a progression in which to execute the sub-queries. Hence, users can impart their priorities with respect to search term variations used in relaxing the main search criteria, which further allows the users to impart their notion of the relevance of results that may be returned by particular sub-queries. A query that includes a sequence of sub-queries is received and the sub-queries are executed, if at all, by a database server in an order based on the progression specified by the user. Response time and network loading are improved through reduction of unnecessary work by the database server and through reduction of costly communications between client and server and associated processing.

Title: Resistant starch with cooking properties similar to untreated starch
Inventor: TAN SLOW YING
IPC: A23L29/20
Filed: 2004-09-07
Abstract: A method has been discovered to produce a resistant starch product that retains the same cooking quality as found in untreated rice starch or flour, but has a higher percentage of starch resistant to a-amylase digestion. This method uses a debranching enzyme, e.g., pullulanase, to digest the starch, but does not require pre-treating the starch source prior to enzymatic treatment.  This method produced resistant starch from low amylose starches, rice starch (24%) and rice flour (20%). Surprisingly the resistant starch product formed by this method retained the pasting characteristics of the untreated flour or starch, and was heat stable. This method may also be used to produce resistant starch from other botanical sources, e.g., corn, wheat, potato, oat, barley, tapioca, sago, and arrowroot. Resistant starch produced by this method has a variety of uses in food products.

Title: Terminator by concatenated tapers on fiber optic
Inventor: COTE ROLAND
IPC: G02B6/36
Filed: 2004-12-23
Abstract: A Terminator by Tapering Fiber Optic (herein after named TermTaper.TM.) made directly using a single mode optical fiber to reduce the back reflection in an installed optical fiber link, which occurs when a guided incident optical signal encounters an index of refraction change at a glass-air transition. The single mode fiber has at one end, a first length of exposed fiber which is obtained by way of stripping the jacket from that portion of fiber. The bare fiber is positioned in a suitable heating set in order to enable a biconical taper to be formed on that portion of bare fiber. The bare fiber with the first formed biconical taper is repositioned in the heating set in order to enable additional biconical tapers to be formed on the same portion of bare fiber. The concatenated biconical tapers contribute to obtain a return loss of better than 55 dB for any guided optical signal that propagates through the TermTaper. The TermTaper is assembled in any type of suitable mounting device.

Title: Retractable step with secure locking mechanism
Inventor: CURI SUZANNA
IPC: B63B27/14
Filed: 2006-06-02
Abstract: A retractable U-shaped ladder assembly preferably for a craft such as a watercraft has a rotatably retracted ladder which is attached to the craft by brackets. A  torsion spring is used to bias the ladder into the retracted position. While the ladder is in an in-use position, the ladder is locked into place by a locking mechanism.  The locking mechanism includes a bent plate which presses against four rings that are fixed to a rod, which rod extends from each bracket. Each ring has a notch that is located in the same position. In the use position, the bent plate will fit into the notches of the rings and lock the step. When the user is finished using the ladder, the user can manually unlock the step by pressing the bent plate. The bent plate moves out of engagement with the notches in the rings, thereby allowing the torsion springs in the brackets to rotate the step to the retracted position.
