Abstract: Processing of banknote- or other security document-images in a computer syst em is sensed, and serves to launch (or direct) a web browser to a web site that  educates the user about limitations on use of such imagery, and/or provides substitute imagery that may be utilized for legitimate purposes. Such images  may be recognized by a digital watermark encoded therein or by other known techniques. The technology is applicable to a wide class of documents that should not be duplicated, including passports, visas, postal stamps, stock certificates, travelers checks, concert/event tickets, lottery tickets, etc.  The technology may also be used for non-security applications, e.g., recognizing images, video, or audio being processed on a user's computer as belonging to a certain class, and presenting the user with a web page relati ng to that class of object. Commerce opportunities may thereby be made availabl e to the user.

Abstract: When the length of the vertical synchronizing signal constantly differs from that of the standard signal, writing of data into the shuffling memory and readout of data therefrom are asynchronous so that overwriting and mixture of data will occur. To deal with this a memory for three frames is used for the shuffling memory. This makes it possible to effect shuffling without causing data mixture.

Abstract: An automatic drive circuit for an ultrasonic probe, such as a dental scaler insert, is operative with a probe which includes a magnetostriction unit, an d a vibratory element to be set into vibration by the magnetostriction unit up on energizing of the magnetostriction unit with an alternating magnetic field. An energizing coil is enclosed within a handle having a compartment for receivi ng the probe. The coil is located within the handle adjacent to the probe receiving compartment for applying the alternating magnetic field to the magnetostriction unit upon insertion of the probe into the handle, and upon energizing the coil by the drive circuit. An oscillator of the drive circuit  is coupled to the coil for applying an oscillatory current to the coil. The drive circuit includes a frequency sensor (72) for sensing a frequency of th e oscillatory current, the sensor outputting a signal designating a magnitude of the frequency. A further component of the drive circuit (16) establishes a value of amplitude of the alternating current in response to the sensed valu e of the frequency. The circuitry relies on the inductance introduced via the magnetostriction unit to the coil for automatically establishing the value o f oscillation frequency commanded by the probe.

Title: Systems and methods for multimedia messaging in a cable or satellite subscriber system
Inventor: MANSON AZITA M
IPC: H04N7/16
Filed: 2000-07-14
Abstract: The present invention comprises customizable, multimedia messaging over a subscriber television system, such as a cable or satellite system, utilizing a service independent framework. The present invention comprises a multimedia messaging (MMM) server generally located at a headend of a cable or satellite system, and an MMM client at a communications terminal located remotely with respect to the MMM server. A service provider or operator defines a message configuration that is utilized to present the message content to one or more subscribers. The message configuration includes parameters that control the presentation of the message content. The MMM server receives an MMM request from a service application, and in response thereto, generates an MMM request which is sent to the communications terminal, and more particularly, to the MMM client. The MMM client processes the MMM request, including the retrieval of any message content or the message configuration. The MMM client then presents the message to the subscriber. Since the MMM server and MMM client are platform independent, any number of different services may send uniquely generated and uniquely designed messages for presentation to a subscriber(s).

Title: Integrated planar optical waveguide and shutter
Inventor: AL-HEMYARI KADHAIR
IPC: G02B6/12
Filed: 2000-11-22
Abstract: An optical switch having an input waveguide and two output waveguides separated by and disposed around a trench. The input waveguide and a first output waveguide have respective optical paths defined by their respective cores; those optical paths (and cores) being aligned or coaxial with each other. Those waveguides are also separated by a trench having a medium provided therein that has a refractive index different from that of the waveguides. The input waveguide and first output waveguide are separated by a distance insufficient to affect the transmission characteristics of an optical signal propagating from the input waveguide to the first output waveguide, even though the optical signal experiences different refractive indices as it propagates from the input waveguide to the first output waveguide. The input waveguide and a second output waveguide are arranged generally on the same side of the trench such that an optical signal passing from the input waveguide to the second output waveguide does not completely traverse the trench. Thus, even though an optical signal passing from the input waveguide to either of the first or second output waveguide encounters different refractive indices, the distance over which the optical signal must travel between the waveguides is small enough so as to not affect the optical transmission characteristics of that signal.
