Filed:

May 24, 2011

Appl. No.:

13/114392

Inventors:

Daniel L. Dickey - Rowlett TX, US

Assignee:

Continental Electronics Corp. - Dallas TX

International Classification:

H04L 27/10

US Classification:

375274, 375239, 375305, 455 93, 332100

Abstract:

A radio transmitter system responsive to a binary signal drives a narrow bandwidth VLF or LF antenna. A generator derives a first variable frequency wave frequency coded based on bit values of a binary signal. An arbitrary impulse response signal processor responsive to the first wave derives a first output signal having real and imaginary components representing the shape of a modulating wave having a variable amplitude envelope and the frequency of the coded values. A transmitter responsive to the processor output signal and a VLF or LF carrier supplies the antenna with another output signal including a modulation wave having a shape that is a substantial replica of the modulating wave shape. The processor causes the signal emitted by the antenna system to include modulation having a shape that is substantially the shape of the first wave.

International Classification:

H05B 6/00
H01P 11/00

US Classification:

219541, 29600

Abstract:

An antenna assembly may be positioned within a wellbore in a subterranean formation. The antenna assembly includes a tubular antenna element to be positioned within the wellbore, and an RF coaxial transmission line to be positioned within the tubular antenna element. The RF coaxial transmission line includes a series of coaxial sections coupled together in end-to-end relation, each coaxial section including an inner conductor, an outer conductor surrounding the inner conductor, and a dielectric therebetween. Each of the outer conductors has opposing threaded ends defining overlapping mechanical threaded joints with adjacent outer conductors.

International Classification:

H04B 104

US Classification:

455110

Abstract:

An FM transmitter includes I and Q channels, each deriving a baseband sinusoidal wave having a frequency determined by speech and/or music broadcast information amplitude and nominally having the same maximum amplitude. Each wave drives a different balanced mixer, each responsive to orthogonally phased carrier waves. Outputs of the mixers are added to derive a frequency modulated output wave. The channels, mixers, and circuitry associated with them tend to introduce unwanted components in the output wave. Offset, peak amplitude, phase and relative delay of the added mixed outputs are such that the unwanted components are substantially eliminated from the output wave. The sinusoidal waves are derived by DACs responsive to signals derived by a digital processor having a memory storing amplitude vs. phase position values and slope vs. phase position values that are combined in response to samples of the broadcast information.

International Classification:

H03F 338

US Classification:

330 10

Abstract:

A power amplifier for a plate load of an AM, RF transmitter includes plural switching stages each powered by a DC source. Each stage is switched from non-sourced to saturation in response to the amplitude of an analog source exceeding a threshold amplitude for the stage; each stage has a different threshold. The thresholds and analog source are arranged so that responses derived between output terminals of the stages change between zero and predetermined amplitudes as the source amplitude changes relative to the thresholds of the different stages. The responses of the different stages are summed. A triangular wave having a small constant maximum amplitude relative to the analog source maximum value effectively changes the threshold of each stage. From time to time the thresholds of different stages are changed so that at different times different stages are in non-sourced and conducting for the same amplitude of the modulating source, while providing the same summed response for the same amplitude of the modulating source.
