Title: Visual search method with feedback loop based on interactive sketch
Inventor: JAPERTAS PRANAS
IPC: G06Q30/00
Filed: 2021-07-14
Abstract: The disclosure relates to the fields of electronic processing of images and e-commerce, specifically - to the visual search with feedback loop based on interactive sketch for transparency and user control. Presented method adds transparency and user control to the traditionally ''black-box" visual search process by introducing a feedback loop, based on interactive sketch. The method comprises of following main steps: submission of an information about the object being searched for by the user (in a form of image, written text, spoken text or selection of product category from menu in GUI), identification of product attributes and verification of identified attributes against the ontology rules, selection of building blocks from database for filtered attributes, connection of selected blocks to form a sketch of object being searched for, application of projection rules to produce a form vector, comparison of vector from previous step with database, presenting user with interactive sketch of product alongside the list of matching products from database, enabling user to select a part of the object in sketch, presenting user with possible modifications for the selected part of the object, enabling user to select needed modification and re-iterate the search process as many times as needed, until the wanted results are achieved.

Patent PT-93331-B (PT)
Inventor: ATTWOOD BRIAN E
IPC: H03F3/38
Filed: 1990-03-02
Abstract: In a digitally controlled amplifier circuit a dc power source is modulated by an oscillator signal for producing a reference square wave signal. A sawtooth signal, double the frequency of the reference signal and synchronized therewith, is compared with a variable input signal to be amplified. When the sawtooth exceeds the input signal a phase shifted version of the reference signal, shifted in phase in accord with the instantaneous amplitude of the variable signal is produced. A switching circuit logically governed by the reference and phase shifted signals produce a pulse width modulated output signal of a selected polarity. An output filter smooths the pulse width modulated output signal and steering diodes control the polarity of the switching circuit.

IPC: F16C39/06
Filed: 1975-01-13
Abstract: A magnetic bearing assembly for levitating a movable member in either rotation or linear translation comprises a three-loop magnetic circuit in which permanent magnets establish a quiescent or fixed flux across four magnetic gaps arranged to provide restoring forces transverse to the direction of gap flux; the resulting inherent instability in the longitudinal direction is overcome by an electric feedback control system which supplies control currents in a pair of coils associated with the magnetic gaps for modulating the permanent magnetic flux therein and thereby provides stabilizing longitudinal magnetic forces. The configuration may be generalized by simple extension to a (2n + 1) loop magnetic circuit with (n + 1) coils.

Title: Arrangement for identifying traffic lying within different frequency ranges in paired cables
Inventor: LATOUR-HENNER A
IPC: H04M3/22
Filed: 1989-01-12
Abstract: The invention relates to an arrangement for identifying traffic in paired cables. The different layers of traffic are distinguished by different levels and frequency ranges. The arrangement comprises a limiter which is connected to the paired cable and transmits an output signal with essentially constant amplitude and a frequency which corresponds to the strongest frequency component of the input signal. The limiter can be constructed from inverters connected to an amplifier or from an amplifier with a Schmitt trigger. The limiter is connected to a frequency indicator which indicates within which frequency range the strongest frequency component lies. The frequency indicator can consist of monostable rockers or a counter and a decoder. The decoder interprets the output signal of the counter and can be constructed from a fixed gate network or a programmable memory. The output signal of the frequency indicator is connected to an indicator which indicates the frequency range concerned, for example by means of flashing light- emitting diodes. <IMAGE>
