Abstract:
Various embodiments of the present invention are directed to crossbar array designs that interfaces wires to address wires, despite misalignments between electrical components and wires. In one embodiment, a nanoscale device may be composed of a first layer of two or more wires (1501-1511) and a second layer of two or more address wires (1512-1523) that overlays the first layer. The nanoscale device may also include an intermediate layer (704-804) positioned between the first layer and the second layer. Two or more redundant electrical component patterns (1400) may be fabricated within the intermediate layer so that one or more of the electrical component patterns is aligned with the first and second layers.
Abstract:
Devices, systems, and methods for enhancing Raman spectroscopy and hyper-Raman are disclosed. A molecular analysis device (100', 100") for performing Raman spectroscopy comprises a substrate (110) and a laser source (120) disposed on the substrate (110). The laser source (120) may be configured for generating a laser radiation (125), which may irradiate an analyte (31 ) disposed on a Raman enhancement structure (300). The Raman enhancement structure (300) may be disposed in a waveguide (130). The molecular analysis device (100', 100") also includes a wavelength demultiplexer (240) and radiation sensors (290) disposed on the substrate (110) and configured for receiving a Raman scattered radiation (160), which may be generated by the irradiation of the analyte (310) and Raman enhancement structure (300).
Abstract:
An apparatus (100) for controlling propagation of incident electromagnetic radiation (110) is described, comprising a composite material (102) having electromagnetically reactive cells (106) of small dimension relative to a wavelength of the incident electromagnetic radiation (110). At least one of a capacitive and inductive property of at least one of the electromagnetically reactive cells (106) is temporally controllable to allow temporal control of an associated effective refactive index encountered by the incident electromagnetic radiation (110) while propagating through the composite material (106).
Abstract:
Tampering with pieces of software is inhibited. The obfuscation of a software image so as to becloud the comprehension of hackers in reverse engineering pieces of software comprising the software image is provided. A process of verifying whether the pieces of software together constitute a software package that requires protection from tampering is also provided. Another process for determining whether the hardware resources, such as the central processing unit or the cache memory on a computing machine, belong to a class for which inhibiting software tampering is possible, is also provided. Thread protection inhibits tampering with various threads that execute protective pieces of software. Service protection inhibits tampering by allowing various unauthorized services to execute. Installation setup protection inhibits tampering during the installation of various pieces of software. Software obfuscation inhibits reverse engineering by hackers by manipulating names of functions and adding jump instructions into various pieces of software. Hardware protection prevents hackers from forcing various pieces of software from running on unauthorized pieces of hardware. Profiles are stored in a central hierarchical database and such profiles are protected from tampering. The obfuscation of a software image so as to becloud the comprehension of hackers in reverse engineering pieces of software comprising the software image is provided. Image verification ensures the originality of the pieces of software to be installed.
Abstract:
Examples of integrated sensors are disclosed herein. An example of an integrated sensor includes a substrate and a sensing member formed on a surface of the substrate. The sensing member includes collapsible signal amplifying structures and an area surrounding the collapsible signal amplifying structures that enables self-positioning of droplets exposed thereto toward the collapsible signal amplifying structures.
Abstract:
Communicating between a first node in a network and a second node includes determining, by a third node in the network that is in communication with the first node, a value of an additive path quality metric for a path segment between the third node and a fourth node, and a value of the additive path quality metric for a path segment between the third node and a fifth node. Path quality is estimated for each of multiple different paths between the first node and the second node based at least in part on the values of the additive path quality metric determined by the third node. At least two of the multiple different paths include at least one path segment in common.
Abstract:
Methods and apparatus to provide packet switched service continuity during circuit switched fallback operation are described. One example method includes determining that a target system does not support packet switched handover; determining if non-3GPP access for packet switched service is available; and triggering handover to the non-3GPP access.
Abstract:
A sender device is able to send packets over a network destined to a receiver device, and the sender device receives response information that is responsive to the packets. A behavior of the sender device with respect to data transmission on plural subflows of a connection is controlled based on the response information.
Abstract:
A circuit includes a plurality of first current-regulator portions, and a second current-regulator portion. The circuit further includes a plurality of switches coupled to the second current-regulator portion. The plurality of switches is configured to sequentially and selectively couple and decouple the first current-regulator portions to the second current-regulator portion to sequentially form a plurality of current regulators. The current regulators are configured to regulate current flow through light emitting diodes (LEDs), which are respectively associated with the first current-regulator portions. The circuit provides for substantially equal luminosity generation by the LEDs via the relatively lowering of voltage and current mismatch between the formed current regulators.

A metal-insulator transition switching device (100) includes a first electrode (120) and a second electrode (125). A channel region (115) which includes a bulk metal-insulator transition material separates the first electrode (120) and the second electrode (125). A method for forming a metal-insulator transition switching device (200) includes depositing a layer of bulk metal-insulator transition material (245) in between a first electrode (220) and a second electrode (225) to form a channel region (115) and forming a gate electrode (210) operatively connected to the channel region (115).
