Title: Method and apparatus for pattern recognition
Inventor: MARSHALL WILLIAM W
IPC: G06V30/10
Filed: 1987-02-13
Granted: 1990-11-27
Abstract: ABSTRACT OF THE DISCLOSURE     A method and apparatus for recognizing an unknown character, pattern, or indicia, or the like as being a particular one of a group of known reference characters, patterns, indicia, or the like.  In the preferred embodiment, the system converts scanned and digitized MICR data and uses it to identify the character.          The reference characters and the unknown character are Fourier Transformed and various corrections are made for eliminating the absolute amplitude difference from the recognition process, while simultaneously providing a method of correcting for position differences between the reference character and the unknown character.   Provisions are made for weighting the phase differences proportional to the expected accuracy of the phase data to minimize the effects of noise on the measurement, and for combining the amplitude and phase data to define a single "best match" criteria for the unknown character.  The input data is stored in memory and later converted to real and imaginary frequency components through the Fourier Transform process.  The real and imaginary parts are converted to amplitude and phase as a function of frequency and both the amplitude and the phase data are corrected for position errors and the like, and then compared to a set of amplitude and phase data for the group of standard known characters.  The particular one of the known reference characters which is closest to the transform of the unknown character is designated as the "best match".  The second minimum is located and the percentage that the best match is better than the second best match is used to determine a margin of error criteria.

Granted: 1991-04-23
Abstract: Abstract A rowing exercise machine having an improved user interface.  The user interface has a cable for accepting user exercising stroke movements each stroke having a power and return portion. The cable is carried on a cable drum which is mounted on a shaft such that when the cable is unwound and rewound rotation to the shaft is imparted.  A flywheel is connected to the shaft for receiving and con-serving angular momentum imparted thereto.  The machine also includes a brake for opposing the rotational displacement of the flywheel.  The user interface further includes a stainless steel eye staked into one end of a strain relief spring with an end of the cable being staked in the opposite end of the spring.  A handle is secured to the eye which is capable of withstanding the concentrated forces to which the user interface is subjected.  A nylon cable port is mounted on the cable drum housing, the cable port having a centrally located aperture therein with cross sections which are generally oval in shape to allow the cable to be pulled out from the cable port along a line generally parallel to the base of the cabinet or at an upward angle with respect to the base without rubbing against the cable port.  The cable drum has an angled sidewall to allow only one row of cable to be wound there around so as to maintain the forces opposing the user constant and controllable.  The cable drum further includes a guide plate positioned between the end plates of the drum so as to lightly rub against the cable and guide it onto the drum in order to prevent tangling of the cable if it is not rewound fast enough.

Abstract: ABSTRACT           Waste oil is treated in a tubular reactor having a length of up to and in excess of 2 km in a plurality of stages each of which involves heating the product to a different temperature and maintaining the product at a different pressure.  The released fractions are evacuated from the path for the flow of waste oil and are immediately condensed and distilled to yield a variety of products from oil having a low boiling point to coke.  One or more withdrawn fractions can be treated (for example, hydrogenated) in one or more discrete tubular reactors.  The heating can involve raising the temperature of waste oil to several times the critical cracking temperature, and the regulation of pressure can involve a reduction of pressure to less than 1 mbar.  The last stage of the reactor can be cleaned by abrasive particles, by vibration at high frequencies and/or by acceleration of the conveyed stream to an elevated speed.

Filed: 1988-02-04
Granted: 1990-06-19
Abstract: SIGNALLING METHOD FOR ESTABLISHING TRUNKED COMMUNICATION Abstract A trunked communication signalling method is provided by a unifying signalling protocol in which subscribers (102, 104) request communication channels (106) using only their individual IDs (404) encoded into single ISWs (402). The central (110) decodes the call reguest, extracts the requesting subscriber's individual ID, which is cross referenced to determine the subscriber's talk-group affiliation(s). If the requesting subscriber's affiliation(s) are not known, the central commands the subscriber to transmit its affiliation using dual ISW signalling (408). In another aspect of the present invention, each subscriber automatically informs the central of a change in talk-group affiliation, thereby providing continual affiliation updates. In this way, many thousand subscribers are afforded access to a single trunked system (100), and control channel traffic congestion is minimized.
