Title: Electro-optical imaging detector array with two axis image motion compensation
Inventor: BERAN STEPHEN R
IPC: H04N5/335
Filed: 1997-04-09
Granted: 2003-06-10
Abstract: An electro-optical imaging array (32) having pixels arranged in rows and columns electronically compensates for image motion in the plane of the array regardless of whether the motion vector is in the row direction, the column direction, or in a diagonal direction, i.e., in some vector combination of row and column directions. In an aerial reconnaissance application, the image motion may be due to rotation of the aircraft (22) about roll (R), pitch (PI) and/or yaw (Y) angles in addition to forward velocity (V) of the aircraft (22). The image motion compensation is achieved with no moving parts and does not require a stabilized platform. The pixel information in the array (32) is transferred in the row and column direction in a step-wise fashion in the row and column directions at a rate and direction substantially matching the image motion.

Title: Statistical thesaurus, method of forming same, and use thereof in query expansion in automated text searching
Inventor: MILLER DAVID JAMES
IPC: G06F17/30
Filed: 1997-03-07
Granted: 2002-04-30
Abstract: A statistical thesaurus is built dynamically, from the same text collection that is being searched, allowing improved generation of expanded query terms . The thesaurus is dynamic in that thesaurus records are collected, ranked, accessed, and applied dynamically. Thesaurus "records" are actually formed a s indexed documents arranged in "collections". The collections are preferably distinguished based on text source. Each record has terms assembled in index ed groups which inherently reflect a ranking based on relevance to an initial query. After an initial query is received, the appropriate collection(s) of records may be searched by a conventional search and retrieval engine, the searches inherently returning records ranked by degree of relevance due the record indexing scheme. A record ranking scheme avoids contamination of relevant records by less relevant records. The record selection and the expansion query term generation processes are each divided into parallel threads. The separate threads correspond to respective text sources to enabl e the improved expansion query term generation to be provided in real time.</S DOAB>

Title: Dual control analog delay element
Inventor: LEE KI-JUN
IPC: H03K5/13
Filed: 1999-02-26
Granted: 2011-01-25
Abstract: The invention is a delay element for simultaneous coarse and fine control of delay of an input clock signal. Coarse control of the delay is accomplished by varying the slope of a ramp signal while fine control is accomplished by varying a threshold voltage. The element comprises a ramp signal generator that generates repetitive ramps, a circuit for varying the slopes of the ramps of the ramp signal, a circuit for receiving a controllable threshold voltage, and a circuit that provides an output clock signal. The control voltages can be made very accurate and immune to temperature and voltage variations. Also, analog circuitry instead of digital circuitry is used.

Patent CA-2269969-C (CA)
Inventor: SCHEFFER STEVEN M
IPC: B65D1/02
Filed: 1999-04-26
Granted: 2002-07-30
Abstract: The invention provides a novel hot fill plastic container with reinforced bands above and below the vacuum panels to prevent panelling (or crease formation under vacuum after cooling) in the label supporting band area. The container has a substantially cylindrical recessed label supporting portion with multiple circumferentially spaced apart vacuum panels. Each panel includes a flat radially recessed central panel face which collapses radially inwardly under vacuum to reduce the volume of the container during cooling of the contents. A like multiple number of elongate posts are defined between the panels and generally reinforce the panel area, however, the top and bottom ends of the posts must be supported or else creases will form in these areas under vacuum. Accordingly, the invention provides for top and bottom cylindrical bands defining the axial upper and lower extent of the panels and posts. The bands include two or more axially spaced apart circumferential hoop ribs, and each rib is composed of recessed rib sections to interrupt the circumferential hoop rib. Each section in axial progression overlaps the adjacent sections of adjacent ribs to prevent crease formation and propagation between rib sections in the otherwise cylindrical band.  Preferably, two or more ribs are distributed to substantially cover each band. Immediately adjacent the posts and panels, rib sections are disposed above and below each post since it has been found by experiment that the area of the bands most likely to develop creases are immediately above and below the posts.

Abstract: An apparatus and method for an alert and signal management device for an already engaged telephone line is described. The device can interface to either a modem or FAX or answering machine, and to a telephone and is triggered by conventional call waiting or distinctive call waiting SAS tones. It will alert by audible and visual means. When a subscriber answers the third party's call a switching circuit is activated that disconnects any local modem or FAX interfaced to the device and signals a switch-hook flash. This allows a call waiting party to commence in conversation or a data-signal to be received. The device also incorporates a switch to select automatic answer mode to allow a subscriber to share an engaged telephone line with in-coming calls to a FAX or answering machine. Upon completion of these in-coming calls the device will automatically switch back to the previously engaged telephonic device.

Title: An aqueous amine fluoride neutralizing composition for metal pretreatments containing organic resin and method for metal pretreatment
Inventor: PAWLIK MICHAEL J
IPC: C23C22/34
Filed: 1998-10-26
Granted: 2004-04-27
Abstract: An amine fluoride neutralizing composition comprised of (a) about 1 to about 50 weight percent hydrofluoric acid, (b) optionally up to about 18 weight percent of a complex fluoride containing compound, and (c) about 45 to about 99 weight percent of an amine. The weight percentages are based on the total solids of the amine fluoride neutralizing composition. Also provided is a method of using the amine fluoride to produce a non-chrome pretreatment composition comprised of mixing from about 20 to about 30 weight percent of the amine fluoride neutralizing composition with about 70 to about 80 weight percent of at least one organic resinous material having an organic resinous material that is amine neutralizable; and adding water so as to achieve a total solids content of the non-chrome pretreatment composition of about 20 to about 60 weight percent. The pretreatment composition may be further diluted with water to form a non-chrome pretreatment bath having a total solids content of about 0.1 to about 10 weight percent, preferably from about 1 to about 5 weight percent. The amine fluoride neutralizing composition allows for a simplified manufacturing process of non-chrome pretreatment compositions by allowing the use of one, less corrosive, easy to handle compound rather than three separate materials which may be hazardous to handle, and it allows for the insertion of fluoride into a pretreatment composition without the introduction of extraneous cations which can destabilize or diminish the effectiveness of the pretreatment concentrate or bath.
