System And Method For Electronically Steering An Antenna

View page
US Patent:
8391376, Mar 5, 2013
Filed:
Mar 17, 2010
Appl. No.:
12/725826
Inventors:
Brecken H. Uhl - La Mesa NM, US
Arthur D. Hurtado - Fairfax VA, US
Daniel A. Law - Washington DC, US
Assignee:
Invertix Corporation - McLean VA
International Classification:
H04L 27/00
US Classification:
375259, 375295, 343700 MS
Abstract:
A system and method for electronically steering an antenna. An array is assembled from direct spatial antenna modulation (DSAM) antenna elements each of which makes use of the spatial characteristics of a radiating antenna structure to directly alter a signal transmitted or received by the radiating structure. A data stream maps a carrier to spatial points directly to In-Phase and Quadrature components (IQ) of the output. The DSAM antennas elements control I and Q directly. The assembled array provides beam forming phase shifts with amplitude only control as well as providing joint modulation and beam forming. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this Abstract.

System And Method For Arbitrary Phase And Amplitude Modulation In An Antenna

View page
US Patent:
8411794, Apr 2, 2013
Filed:
Mar 17, 2010
Appl. No.:
12/725773
Inventors:
Brecken H. Uhl - La Mesa NM, US
Arthur D. Hurtado - Fairfax VA, US
Daniel A. Law - Washington DC, US
Assignee:
Invertix Corporation - McLean VA
International Classification:
H04L 27/00
US Classification:
375299
Abstract:
A system and method for arbitrarily switching phase and amplitude at an antenna. A Direct Spatial Antenna Modulation (DSAM) system makes use of the spatial characteristics of a radiating antenna structure to directly alter a signal transmitted or received by the radiating structure. A data stream maps a carrier to different spatial points of excitation in the antenna structure, where each chosen configuration has different radiating characteristics including phase, amplitude, and polarization, which can be used represent data symbols. The spatial points of a radiating structure may be mapped directly to In-Phase and Quadrature components of the output using two spatial feedpoints and amplitude control to the feedpoints. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this Abstract.

System And Method For Spreading And De-Spreading A Signal At An Antenna

View page
US Patent:
8457251, Jun 4, 2013
Filed:
Mar 17, 2010
Appl. No.:
12/725721
Inventors:
Brecken H. Uhl - La Mesa NM, US
Arthur D. Hurtado - Fairfax VA, US
Daniel A. Law - Washington DC, US
Assignee:
Invertix Corporation - McClean VA
International Classification:
H04L 27/00
US Classification:
375299
Abstract:
A system and method for spreading and de-spreading a signal at an antenna. A Direct Spatial Antenna Modulation (DSAM) system makes use of the spatial characteristics of a radiating antenna structure to directly alter a signal transmitted or received by the radiating structure. When used for transmitting data, a data stream maps a signal to different spatial points of excitation in the antenna structure, where each chosen configuration has different radiating characteristics including phase, amplitude, and polarization, which can be used to represent data symbols. A code spreading sequence is applied to switch the output of the DSAM antenna to spatial points in the antenna to spread an input signal. The code spreading sequence is applied to an antenna to de-spread a previously spread signal. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this Abstract.

Method And System For Improving Wireless Link Performance

View page
US Patent:
20070275664, Nov 29, 2007
Filed:
May 29, 2007
Appl. No.:
11/754997
Inventors:
Brecken Uhl - Las Cruces NM, US
Assignee:
Signature Devices, Inc. - Sunnyvale CA
International Classification:
H04B 17/00
H04M 1/00
US Classification:
455 6711, 4555621
Abstract:
A system to enhance the performance of bi-directional wireless devices while operating within regulatory parameters utilizes at least two units. Each unit receives a signal from a transceiver. The signal may either be a transmit or receive signal and is sampled using a directional coupler and a power detector. A sample portion is sent to a logical decision device controlling the path the signal will take. Transmissions will be sent to an appropriate antenna for transmitting; however, receive signals will be routed to dedicated receiving antennas or arrays, thus increasing the range. Since each unit is thus enhanced, each user of the present invention receives the benefit without expensive retrofits or re-designs. In another embodiment, a control signal is generating a control circuit and directs the input to the appropriate antenna without the need for the directional coupler, power detector or logical decision device.

System And Method For Modulating A Signal At An Antenna

View page
US Patent:
20090220030, Sep 3, 2009
Filed:
Nov 25, 2008
Appl. No.:
12/277901
Inventors:
Brecken H. Uhl - La Mesa NM, US
Arthur D. Hurtado - Fairfax VA, US
Daniel A. Law - Washington DC, US
International Classification:
H04L 27/22
H04L 27/06
US Classification:
375329, 375340
Abstract:
A Direct Spatial Antenna Modulation (DSAM) antenna structure makes use of the instantaneous electromagnetic field state of a radiating antenna structure to achieve direct modulation of a transmitted signal within the antenna. In contrast to existing amplitude and phase-only based digital modulation techniques, this innovative technique utilizes an inherent spatial modulation component, mapping data spatially to different locations in the antenna structure, where each location has different transmitting and receiving properties. This spatial component of the modulation can enable, for example, a unique increase in data transmission speed in a fixed spectral bandwidth with no increase in bit error rate over current phase and amplitude only modulation techniques. Additionally, the DSAM antenna structure affords important benefits in reduced hardware complexity, reduced supply current consumption, and relaxed amplifier linearity requirements. This abstract is not to be considered limiting, since other embodiments may deviate from the features described in this Abstract.

Unidirectional Sampling Mixer

View page
US Patent:
20130165066, Jun 27, 2013
Filed:
Dec 18, 2012
Appl. No.:
13/718692
Inventors:
Brecken H. Uhl - La Mesa NM, US
Daniel A. Law - Washington DC, US
Assignee:
Invertex Corporation - McLean VA
International Classification:
H04B 1/16
US Classification:
455208
Abstract:
A unidirectional sampling mixer utilizes a stepped phase modulation to shift the frequency of an RF input signal supplied to an RF input switch. An ordered set of phase shift values to be applied to the RF input signal and a set of times each element of which corresponds to a time at which a phase shift value is be applied to the RF signal are determined. For each phase shift value, a controller controls the RF input switch to select an input of a phase shifting device and controls an RF output switch to select an output of the phasing shifting device. The input and the output of the phase shifting device are selected to apply the phase shift value at its corresponding time to the RF input signal. A frequency shifted signal is supplied to an RF output port from an output of the RF output switch.

Multi-Antenna Detection, Localization, And Filtering Of Complex Time-And-Doppler-Shifted Signals

View page
US Patent:
20200386851, Dec 10, 2020
Filed:
Jun 5, 2019
Appl. No.:
16/432567
Inventors:
- Tuscon AZ, US
Brecken Uhl - Tucson AZ, US
International Classification:
G01S 5/06
G01S 5/04
Abstract:
Systems and methods for detecting, localizing, and filtering signals such as radiofrequency signals using an array of antennas are disclosed. Input signals each containing a signal of interested are received, along with a reference signal sharing one or more characteristics of the signal-of-interest. Predetermined time delays and frequency shifts are applied to the input signals such that the signal-of-interest components of the signals are synchronized and to cancel any Doppler-shifting between the signal-of-interest components. A filtering process is employed to filter the shifted input signals and sum them such that a metric indicating the degree of difference between the reference signal and the summed filtered signals (such as the mean squared error, for example) is minimized.

Abstract:
In general, this disclosure describes techniques for a health management system that schedules medical appointments based on a dialog with a user (e.g., a patient), clinical guideline information, and/or other information. The health management system may engage in a dialog with the user, the dialog including requests from the health management system for audio input to the user device and audio input from the user in response to each request. The health management system may extract information from the audio input and compare the extracted information to clinical guideline information to determine one or more probable health conditions of the user. The health management system may determine a time allotment, identify a health care provider type and a platform for a medical appointment based on the one or more probable health conditions.
