Inventors:

Li Leah WANG - Fremont CA, US

Assignee:

Lockheed Martin Corporation - Bethesda MD

International Classification:

H04B 5/00

US Classification:

307104

Abstract:

Various aspects of the subject technology include a wireless power transmission design based on extended range near-field resonance coupling induction, where magnetic near-field range may be extended by several orders of magnitude. One element that may help to accomplish the near-field extension, in one aspect, is the addition of a transformational magnetic lens to the transmitter. The magnetic lens may be made of metamaterials with refractive index of for example, −1. It may recover and collimate the near-field evanescent, magnetic flux, effectively extending the near-field coupling distance by several orders of magnitude.

International Classification:

G01R 31305
G01R 3102

US Classification:

324751

Abstract:

A method for detecting electrical defects in a semiconductor wafer, includes the steps of: a) applying charge to the wafer such that electrically isolated structures are raised to a voltage relative to electrically grounded structures; b) obtaining voltage contrast data for at least a portion of the wafer containing such structures using an electron beam; and c) analyzing the voltage contrast data to detect structures at voltages different from predetermined voltages for such structures. Voltage contrast data can take one of a number of forms. In a simple form, data for a number of positions on a line scan of an electron beam can be taken and displayed or stored as a series of voltage levels and scan positions. Alternatively, the data from a series of scans can be displayed as a voltage contrast image. Analysis can be achieved by comparison of one set of voltage contrast data, for example voltage contrast data from one die on a wafer, with one or more other such sets, for example voltage contrast data for corresponding structures on one or more preceding dice, so as to determine differences therebetween.

C12Q 1/682

Abstract:

The invention relates to methods of multiplex detection of a plurality of target nucleic acids by contacting a sample with an acid reagent to remove bound nucleic acid detection systems, thereby allowing the same detection systems to be used again to detect different target nucleic acids and to provide for higher levels of multiplexing. The invention also relates to kits containing an acid reagent and optionally probes for detection of target nucleic acids.

H04B 5/00

Abstract:

An optimized near-field communication (NFC) antenna structure for reduced coupling with a wireless charging (WLC) coil of a computing device includes the WLC coil and an NFC coil that at least partially overlaps the WLC coil. The NFC coil of the optimized structure may include two sections that partially overlap the WLC coil and meet, over the WLC coil, at an angle to reduce coupling between the WLC coil and the NFC coil. The angled shape of the NFC coil may be implemented in various shapes resulting in one or more angles such that the first and second sections of the NFC coil are angled with respect to one another over the WLC coil. The combination or shape of the angles of the NFC coil, as well as NFC coil position relative to the WLC coil, may be optimized to reduce coupling between the NFC coil and the WLC coil.
