Appl. No.:

13/341916

Inventors:

Daniel G. Knierim - Beaverton OR, US
James S. Lamb - Portland OR, US
Josiah A. Bartlett - Forest Grove OR, US

Assignee:

Tektronix, Inc. - Beaverton OR

International Classification:

H04B 3/00

US Classification:

375257, 375258, 375219, 375295, 375316

Abstract:

A balun structure is disclosed having positive and negative going signal paths coupled to a ninety degree hybrid. The positive signal path has a circuit trace and a phase shaper structure that provides three hundred and sixty degrees of phase shift at Port 1 of the hybrid. The negative going signal path has a circuit trace and a second order phase shaper that provides four hundred and fifty degrees of phase shift at Port 2 of the hybrid. Port 1 is coupled to Port 3 of the hybrid and functions as an output port. The first order phase shaper and the second order phase shaper compensate for the signal loss caused by a signal cable coupled to the output port and provide a frequency band from DC to at least 15 GHz and a transient response having less than ten percent pre-shoot.

International Classification:

G06Q 50/16

Abstract:

A computer-implemented method to provide information characterizing real-estate market conditions within a geographic sub-region included within a larger geographic region is described herein. An indication of the geographic sub-region is received from a user. A memory device on which is stored information characterizing a set of parcels of real property that have been listed for sale is accessed. A parcel of real property located in the sub-region and for which a purchase offer has been made is identified from the stored information. If a purchase transaction for the parcel of real property has not closed, a range of a plurality of values characterizing the purchase offer is provided in at least one graphical user interface. If a purchase transaction for the parcel of real property has closed, a specific value of the plurality of values characterizing the purchase offer is provided in at least one graphical user interface.
