Assignee:

Microsoft Corporation - Redmond WA

International Classification:

G06F 17/00

US Classification:

235375, 235487, 235380, 235382, 704201, 343846, 375173, 375132, 375261, 705 39, 705 59, 705 75

Abstract:

Radio frequency certificates of authenticity (RFCOAs) are presented. In one implementation, a scattering agent is attached to an object to provide a reproducible radio frequency (RF) fingerprint that can be used to authenticate a tag or a seal for the object. In one implementation, the RF fingerprint is measured and digitized, combined with information associated with the object to which the RFCOA is attached, and stored in a radio frequency identification (RFID) system associated with the RFCOA. A scanner receives the fingerprint and the information and authenticates the information by comparing the fingerprint against a new fingerprint obtained from the object.

International Classification:

H01Q 5/00

US Classification:

343700MS, 343702, 343893

Abstract:

A bent monopole antenna with shared segments is capable of tri-band communication. In an example embodiment, an antenna assembly includes a substrate, a first bent monopole, a second bent monopole, and a third bent monopole. The first, second, and third bent monopoles are disposed on the substrate. The first bent monopole includes a feedline segment and a first segment. The second bent monopole includes the feedline segment and the first segment. The third bent monopole includes the feedline segment and a second segment. The first, second, and third bent monopoles share the feedline segment, while the first and second bent monopoles also share the first segment. A T-junction is formed by the feedline segment, the first segment, and the second segment. In an example implementation, the first segment has a first width, and the second segment has a second width, with the first width being greater than the second width.

International Classification:

H01Q 13/10

US Classification:

343770, 343767

Abstract:

Technology is described for a slot antenna. The slot antenna can include a substrate having a metal layer on a first side of the substrate. A feed line can be located on a second side of the substrate. A first polygon shaped slot can be formed in the metal layer of a first side of the substrate. A second polygon shaped slot can also be formed in the metal layer of the first side of the substrate. The second polygon shaped slot can be recessed within a perimeter of the first polygon shaped slot and the second polygon shaped slot and first polygon shaped slot share a common side. Examples of the first and second polygon shapes may include square or diamond shapes.

US Classification:

343702, 343846, 343700 MS

Abstract:

Mobile device antennas with dielectric loading are described herein. In one example, a mobile device includes a ground plane, carried within an enclosure. An antenna is connected to the ground plane. Dielectric loading material is provided within at least a portion of an area defined between the ground plane and the antenna. The dielectric loading material results in a shortening of a required antenna length, thereby creating a recovered area, i. e. , valuable space within the enclosure “recovered” by the use of dielectric loading material.

Abstract:

The subject innovation relates to systems and/or methodologies for using randomly positioned electromagnetic scatterers deposited into a predetermined region of an optical storage medium (e. g. , Blue Ray DVD, HD DVD, CD, etc. ) as a distinct three dimensional (3D) hard-to-copy digital rights management feature. A scatterers' topology is scanned using a matrix of antennas that sense the scatterers' electromagnetic response as the optical disc revolves at near-constant angular speed. The response, f, called an RF fingerprint, is then concatenated with an arbitrary text, t, that defines the digital rights management information imposed by the disk publisher.

International Classification:

H01Q 1/38

US Classification:

343700MS

Abstract:

Described is an antenna having a patch with slits configured to meet specified frequency and bandwidth requirements. For example, for a dual-polarized antenna with two feedlines, the patch has three slits that are configured to determine the antenna's frequency characteristics; the patch has no (or a substantially reduced) fourth slit, thereby providing wider bandwidth. The slits may be sized to provide the desired frequency characteristics. Also described is having the equivalent of variable slits via electronic or mechanical configuration. For diagonal feedlines, the slits may be symmetrically arranged, e.g., one horizontal slit extending from one side of the patch and two vertical slits extending from the upper and lower edges of the patch. The antenna may be used in a device such as a gaming console.

International Classification:

US Classification:

Abstract:

A sensor has a strip resonator filter that energizes an emitter patch which emits an electric field out from the strip resonator filter (away from the strip resonator filter). The capacitance of the filter, or specifically the coupling capacitance and radiation pattern of the slotted patch, is altered when an object such as a finger is near the sensor. Resulting changes in a signal outputted by the filter can be used to determine how close the object is to the sensor. The strip resonator filter may be a half wavelength strip resonator coupled filter having three separate strips. The patch may have a slot and two accompanying strips. An arrangement of multiple sensors may detect the position of an object in two or three dimensions.
