February 6, 2014



By a News Reporter-Staff News Editor at Politics & Government Week -- According to news reporting originating from Washington, D.C., by VerticalNews journalists, a patent application by the inventors Van Ausdall, Terrence Lee (Boulder Creek, CA); Hoffmann, Mathieu (San Diego, CA); Monney, Pascal (San Diego, CA), filed on July 13, 2012, was made available online on January 23, 2014.

The assignee for this patent application is Semtech Corporation.

Reporters obtained the following quote from the background information supplied by the inventors: "Many electronic devices include components that emit radio-frequency (RF) electromagnetic field (EMF) emissions. Examples of such electronic devices include mobile communication devices, tablet computing devices, laptop computing devices, and the like. Human exposure to these RF EMF emissions is harmful if the radiation power is high, at close range, and/or over a prolonged time."

In addition to obtaining background information on this patent application, VerticalNews editors also obtained the inventors' summary information for this patent application: "The following presents a simplified summary to provide a basic understanding of some aspects of the subject disclosure. This summary is not an extensive overview of the disclosed subject matter. It is not intended to identify key or critical elements of the disclosed subject matter, nor is it intended to delineate the scope of the subject disclosure or the claims. Its sole purpose is to present some concepts of the disclosed subject matter in a simplified form as a prelude to the more detailed description presented later.

"In a non-limiting embodiment of the subject disclosure, a system is described that can be used as a body proximity sensor. The system includes a first sensor and a second sensor. The first sensor has a first shape and detects a first capacitance related to an object. The second sensor has a second shape different from the first shape and detects a second capacitance related to the object. The system also includes an electronic component that processes the first capacitance and the second capacitance to facilitate discrimination of whether the object is a human body or a non-human object.

"In another non-limiting embodiment, a method is described. The method can be used to determine whether an object is a human body or a non-human object. The method includes processing a first capacitance from a first sensor with a first shape and a second capacitance from a second sensor with a second shape different from the first sensor. The method also includes determining a type of object in proximity of the first sensor and the second sensor based on the first capacitance and the second capacitance.

"In a further non-limiting embodiment, an apparatus is described. The apparatus can be used as a body proximity sensor. The apparatus includes a first sensor and a second sensor. The first sensor has a first shape and detects a first capacitance. The second sensor has a second shape different from the first shape and detects a second capacitance. The apparatus also includes an electronic component that processes the first capacitance and the second capacitance to facilitate determination of whether the object is a human body or a non-human object.

"The following description and the annexed drawings set forth in detail certain illustrative aspects of the disclosed subject matter. These aspects are indicative, however, of a few of the various ways in which the principles of the innovation may be employed. The disclosed subject matter is intended to include all such aspects and their equivalents. Other advantages and distinctive features of the disclosed subject matter will become apparent from the following detailed description of the innovation when considered in conjunction with the drawings.

BRIEF DESCRIPTION OF THE DRAWINGS

"Non-limiting and non-exhaustive embodiments of the subject disclosure are described with reference to the following figures, wherein like reference numerals refer to like parts throughout the various views unless otherwise specified.

"FIG. 1 is a schematic illustration of an example body detection system, according to an embodiment of the subject disclosure;

"FIG. 2 is a schematic illustration of an example sensor design for a body detection system, according to an embodiment of the subject disclosure;

"FIGS. 3 and 4 are schematic illustrations of example two-dimensionally symmetrical sensor designs for a body detection system, according to an embodiment of the subject disclosure;

"FIG. 5 is a schematic illustration of an example fully symmetrical sensor design for a body detection system, according to an embodiment of the subject disclosure;

"FIG. 6 is a schematic illustration of an example capacitive human body/inanimate object discrimination system, according to an embodiment of the subject disclosure;

"FIG. 7 is a schematic illustration of a system that reduces emissions when a human body is detected, according to an embodiment of the subject disclosure;

"FIG. 8 is a process flow diagram illustrating a method for discriminating between a human body and an inanimate object, according to an embodiment of the subject disclosure;

"FIG. 9 is a process flow diagram illustrating a method for discriminating between a human body and an inanimate object based on digital signals, according to an embodiment of the subject disclosure; and

"FIG. 10 is a process flow diagram illustrating a method for reducing radiation emissions if a human body is in proximity, according to an embodiment of the subject disclosure."
