Steven Allen Murphy - Apple Valley MN
Rick Clevie Stevens - Apple Valley MN

Assignee:

Unisys Corporation - Blue Bell PA

International Classification:

G06F 1300

US Classification:

395311

Abstract:

A deadlock avoidance system for avoiding interconnection deadlocks between a plurality of data transfer devices includes a controller, a switch interconnector coupled to all of said data transfer devices for interconnecting on a one-to-one basis selected ones of the data transfer device as requesting units to selected ones of said data transfer devices as receiving units. A transfer queue is employed that includes a master transfer register and a slave transfer register, a master register, a slave register and a target register.

David P. Andersen - Burnsville MN
Michael Farmer - Eagan MN

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

A01F 1250

US Classification:

460 6

Abstract:

A device to measure the volume and weight of a harvested grain crop during the harvesting of the grain crop with a weight measurement member including an elevator for moving grain from a lower elevation to a higher elevation with the elevator having a rotatable belt and a set of paddies thereon for moving grain from the lower elevation to the higher elevation with a torque sensor to determine the increase in torque on the shaft as a result of having to raise the kernels of grain from the lower elevation to the higher elevation and an acoustic volume measurement member to obtain information on the depth of the grain that is correlatable to volume of the harvested crop.

Appl. No.:

8/143597

Assignee:

Loral Corporation - New York NY

International Classification:

G01S 744

US Classification:

342185

Abstract:

A pseudo-code representation and a C language representation of a scan converter system whereby radar amplitude data specified in polar coordinates may be displayed on a computer monitor display controlled by rectangular coordinates is provided. The invention utilizes a look-up table that is built using a two-phase algorithm. The look-up table is set into an initial state after which a mapping process takes place in which all of the (x,y) coordinate values covering the display area are inversely projected to the nearest (r,. theta. ) coordinate values using trigonometric and approximation procedures. Since more than one (x,y) value may map to the same (r,. theta. ) value, these values are linked together to form a patch. All of the (r,. theta. ) coordinates will not be hit in this mapping process.

Appl. No.:

8/257257

Inventors:

Assignee:

Loral Corporation - New York NY

International Classification:

A01G 1300

US Classification:

47 17

Abstract:

A smart weed recognition and identification system comprises a chlorophyll sensor for detecting green vegetation and memory map means for storing images which contain different forms of green vegetation. The memory maps stored in memory are processed to eliminate the background information and leave a memory map containing only green vegetation. The enhanced memory map is further processed by an operation of segmentation into identifiable regions and the identifiable green vegetation regions are processed to identify unique attributes for each of the regions. The unique attributes for each of the regions is stored in a reference data base library and are used as reference data for comparing other green vegetation with the data stored in the base model by a processor which matches green vegetation in other regions with the green vegetation stored in said reference data base model and further produces decision data signals which are used by a controller to control a plurality of spray nozzles covering the area sensed and for dispensing a plurality of selectable controlled chemicals.

International Classification:

G01S 1390

US Classification:

342 25

Abstract:

Inverse synthetic aperture radar imaging systems that are used to image targets that undergo rotational accelerations are enhanced by signal processing techniques which provide correction factors to reduce the frequency-shift and frequency-stretch errors that occur due to such accelerations. A target scan is subdivided into a number of sub-apertures and a Fast Fourier Transfer (FFT) is performed on the data for each sub-aperture to provide associated frequency sub-images. The FFT is then subdivided in "sub-swaths" of amplitude versus frequency for a plurality of frequency bands. The change-of-frequency, or frequency shift, data between prominent scattering points of each sub-image are processed to provide a phase correction factor that incorporates range changes and translational acceleration distortions for additional scattering points other than the most prominent scattering point. A frequency-stretch correction factor that compensates for rotational acceleration distortion is also provided.
