Patent number: 5495553Abstract: A recognition device and method for recognizing a voice message in the form of pulse code modulation (PCM) digital signals indicative of samples of the voice message. The device and method are adapted such that a recognition result is not provided if the digital signal content satisfies certain requirements which are indicative of a likely erroneous recognition result. The recognition device and method are further adapted to reduce errors in recognizing voice messages of the same message content but different amplitude, as well as to permit simultaneous recognition and storing for recording of a voice message.Type: GrantFiled: December 20, 1993Date of Patent: February 27, 1996Assignee: Nynex CorporationInventor: Priya Jakatdar

Patent number: 5288976Abstract: A system which utilizes a bar code having an instruction field whose data specifies an action to be performed and also having a reference field whose data relates to the data in the instruction field. The system reads the instruction and reference fields of the bar code and processess the read data. This processing may determine from the instruction field data that the action or actions to be taken are to be taken on data other than that in the reference field of the bar code. It also may determine from the data in the instruction field that an action to be taken on the data in the reference field is other than an action identified in the instruction field of the bar code. Based on these determinations, the system continues the processing using the appropriate action and data.A unique bar is also used in the system. This bar code, between its start and stop fields, has a separator field whose width is greater than that of any of the individual bar code characters.Type: GrantFiled: July 15, 1991Date of Patent: February 22, 1994Assignee: Nynex CorporationInventors: Howard Citron, Robert Springer

Patent number: 5237628Abstract: A system and method for automatically processing machine printed forms which are filled out by hand are disclosed. The inventive system and method eliminate the use of a manual data entry step. Typically each form has one or more fields, each field having a machine printed field identifier such as the words "name" or "social security number" and the corresponding information which is filled in by hand. A scanner or other device forms a digital image of each form. An optical recognition engine searches the digital image of each form through use of an algorithm which can recognize machine printed but not handwritten characters to locate the fields in the digital image by locating the machine printed field identifiers. An offline handwritten character recognition algorithm is then utilized to recognize the handwritten characters in each individual field. Symbolic information corresponding to the recognized handwritten characters is then stored in a database in a memory.Type: GrantFiled: June 3, 1991Date of Patent: August 17, 1993Assignee: NYNEX CorporationInventor: Arthur C. Levitan

Patent number: 5111481Abstract: A dual mode LMS channel equalizer is disclosed. The inventive channel equalizer utilizes an LMS algorithm to both identify channel parameters and to smooth the received data signal to mitigate the effects of channel additive noise. In real time operation, the inventive equalizer first identifies the channel parameters in a training period. Thereafter, the same LMS algorithm is switched to smooth the received data signal, while intermittently, the LMS algorithm is switched back to track the slowly changing channel parameters. In comparison with the conventional LMS adaptive channel equalizer, the inventive dual mode channel equalizer achieves a significant performance improvement at little additional cost.Type: GrantFiled: November 17, 1989Date of Patent: May 5, 1992Assignee: Nynex CorporationInventors: Walter Y. Chen, Richard A. Haddad

Patent number: 5111453Abstract: An apparatus and method for recognizing destination addresses in information packets wherein a recognition that a destination address corresponds to a source address is made based upon a first match decision in which fragments of the destination address are compared with representations of corresponding fragments of source addresses and a second match decision in which fragments of a scrambled version of the destination address are compared with representations of corresponding fragments of similarly scrambled versions of the source addresses.Type: GrantFiled: May 18, 1990Date of Patent: May 5, 1992Assignee: Nynex CorporationInventor: Joel I. Morrow

Patent number: 5093841Abstract: A circuit and method is disclosed for recovering the transmitter clock at a receiver in a direct sequence spread spectrum communication system where a transmitter and receiver run independent clocks of nominally the same frequency. At the receiver, to select the phase of the local clock that yields the strongest signal, a clock recovery circuitry cycles through M phases of the locally generated receiver clock. The cycling is halted and the phase is locked soon as an indication is obtained that a phase is valid. Alternatively, all M phases of the local clock are tested for validity or invalidity, and depending on the resulting pattern of valid and invalid phases, a particular phase is selected for the local clock. A phase is valid or invalid depending on whether there is a second correlation crossing at the expected instant one data bit period after a first correlation crossing.Type: GrantFiled: January 30, 1990Date of Patent: March 3, 1992Assignee: NYNEX CorporationInventor: Jan P. Vancraeynest
