Title: Using a category to analyze an image showing a graphical representation
Inventor: MAHONEY JAMES V
IPC: G06V30/40
Filed: 1994-10-18
Granted: 1999-09-07
Abstract: Image data define an image that shows an input graphical representation whose configuration represents information. The image can show a sketch, for example. The image data are used to obtain category data indicating a category of graphical representations. For example, the category data could indicate any of X-Y graph, directed graph, undirected graph, bar graph, pie chart, line graph, scatter plot, circuit diagram, flow chart, Venn diagram, state-transition diagram, tree, table, matrix, or array. The category data could also indicate a specific category within a generic category such as bar graph or pie chart. The category data can be obtained by determining whether the graphical representation satisfies a constraint on each category. Each category's constraint may be applied to parts of the input image that meet a feature candidate criterion, which may be different for each specific category in a generic category, even though the feature candidates must satisfy another constraint that is the same for all specific categories in the generic category. The category data are then used to obtain content data indicating information represented by the input graphical representation's configuration, and an output image is obtained with an output graphical representation, with a configuration representing the information indicated by the content data. The output graphical representation can be more precisely formed than the input graphical representation. The output graphical representation can be in the same generic category as the input graphical representation, but possibly in a different specific category, or it can be in a different generic category.

Title: Hollow polymer latex particles
Inventor: LEE DO I
IPC: D21H19/42
Filed: 1992-08-19
Granted: 2003-07-08
Abstract: This invention relates to polymer particles that are acid-free in the swellable polymer core and to hollow polymer particles derived therefrom, and to a process for the production of these particles. The acid-free core advantageously decreases the polym-er particle's affinity to water. Applicants have discovered that non-carboxylated latexes having a variety of T g's will swell at tem-peratures higher than the T g of the polymer. These latex particles are useful as opacifying plastic pigments for various coat-ings and particularly as gloss-enhancing plastic pigments for paper and paperboard coatings. Preparation of the hollow polymer particle comprises the use of (meth)acrylate ester monomers, vinyl esters of carboxylic acids or a mixture thereof which are hydrolyzable and swellable at higher temperatures in alkaline environments. The particles may be encapsulated with a hard shell.

Inventor: ANSLEY DAVID A
IPC: G02B26/10
Filed: 1995-01-13
Granted: 1998-01-06
Abstract: A  lightweight  fiber  optic  television  subminiature display for helmet mounted display systems. A one dimensional sional array of pixels such as a fiber optic (FO) ribbon (64)  has an input end  (62)  which receives input light illuminating the pixels so as to create a first dimension of the display. The output end (64B) of the FO ribbon is moved relative to the observer to create a second dimension. At the helmet (66), the Fo ribbon is clamped by a clamp (68) and vibrated by a driver (70) so that the output end of the ribbon is moved to obtain the second dimension. The dimensions of the FO ribbon are selected to provide a natural resonant frequency equal to the television field rate,  and the driver vibrates the section  (64A)  of the ribbon between the clamp and the ribbon output end at the ribbon resonant frequency.   The clamp and driver can be very  lightweight,  thereby  reducing  the  weight  of  the display elements mounted on the helmet.

Filed: 1995-01-31
Granted: 1998-08-18
Abstract: The prior art deficiencies are solved, in accordance with the disclosure herein, by maintaining a list of caller identities and by determining, via reference to this list, the type of call treatment that an incoming call should receive. Thistechnique may be termed "divergent call treatment". The caller identities may betelephone numbers. The list of telephone numbers may be stored in the telephone company's switching facilities or in the subscriber's telephone instrument. A wide range of call treatment options are provided, and these options can be performedregardless of whether the list is maintained in the telephone company's switching facilities or in the subscriber's telephone instrument. In connection with cellular telephones, the divergent call treatment technique of the present invention is used to particular advantage. In accordance with one of the embodiments disclosed below, for example, the list maintained is a list of accepted callers, and it is maintained by the telephone service supplier. When a call comes in, a determination is made as to whether the caller is an "accepted" caller. If so, the call is forwarded to the cellular telephone. Otherwise, the caller is offered the option to pay for the call. A willingness on the part of the caller to pay for the call is indicated by a signal from the caller. This signal may be, for example, the pressing of one or more keys on a standard DTMF touch-tone pad, such as #1. In response to such a signal, the call is forwarded to the cellular telephone. In the absence of such a signal, the call is disconnected or diverted, for example, to the land line phone of the cellular telephone subscriber. When the list of accepted callers is maintained in the subscriber's telephone instrument, means are included to attenuate the ringing signal for an interval sufficient to provide appropriate call treatment for the call and, optionally, means are included for call forwarding, and/or recording of incoming messages.
