Inventor: ADAMS GENE W
IPC: G01S13/44
Filed: 1987-04-13
Granted: 1990-12-11
Abstract: ABSTRACT     A system for simultaneously locating a plurality of targets and distinguishing the targets from noise which utilizes phase detector techniques to generate complex voltage signals and obtain phase information. Spectral analysis is performed on the complex voltage temporal functions to generate doppler frequency functions.  Both spectral phase functions and spectral amplitude functions are generated from the doppler frequency functions.  Spectral phase functions are analyzed using interferometry techniques to determine if a potential target has a common locational source from returns of a plurality of sensors.  A zenith angle is also generated using interferometry techniques to provide locational information of the multiple targets.  Range gating and two frequency range detection methods provide high resolution range information as to the location of the targets.  High resolution range information and two dimensional zenith angle information are used to provide an image of the targets.  The present invention uses a two-frequency pulse which can be generated simultaneously or sequenced within a pulse in a manner which is phase coherent.  The two-frequency pulse eliminates problems associated with range aliasing, zenith angle aliasing, scattering point analysis and allows for range location with high resolution.  An error correction factor is also generated which eliminates spectral smearing.

Abstract: AUTOMATIC VOICE PROCESSING ASSISTED CUSTOMER INFORMATION SYSTEM    Abstract A vendor information service is offered utilizing the services of attendants for identifying customer requests and for taking orders, utilizing a voice processing unit for announcing prerecorded information to customers and for recognizing voice commands or keyed requests.  Such commands or requests may be to announce another message to a customer, to set up a connection to a telephone operator, or to connect the customer directly to a vendor.  A customer is initially connected to a telephone operator who ascertains the basic customer request.  In response to that request, the operator sets up an announcement for the customer.  A voice processing unit then monitors the customer for voice commands or keyed requests in order to play another announcement or to set up a connection from the customer to another telephone operator or a vendor attendant.  Advantageously, such an arrangement utilizes operator and vendor attendant time efficiently and permits advertising announcements to be played only to those customers who specifically request them.

Abstract: ABSTRACT   Programmable logic cells, and arrays of those cells, having certain characteristics, including:          (1) the ability to program each cell to act either as a logic element or as a logical identity element(s) between one or more inputs and one or more outputs; (2) the ability to rotate circuits by 90° and to reflect circuits about horizontal and vertical axes; (3) an integrated logic and communication structure which emphasizes strictly local communications; (4) simple logic functions available at the cell level, making available a very fine-grained logic structure; and (5) suitability for implementation of both synchronous and asynchronous logic, including speed-independent circuits.  Cells are arranged in a grid, with each cell communicating with its north, east, west and south neighbors.  The cells are programmable to several states.  Using a graphics-based programming environment, the user may construct systems at a pictorial block diagram level, rather than having to be concerned about the detailed implementation of the internal structure of each block.  Blocks may be rotated and they may be reflected about horizontal and vertical axes, to place their input and output connections on different sides and positions without altering the internal electrical operation of the blocks.
