| 20120092543 | Optical Lens Having Fixed Lenses And Embedded Active Optics - An electrically controllable optical lens apparatus makes use of fixed lenses and an active optical element together in a lens enclosure. The enclosure may be a barrel structure that is easily mounted to a camera device having an image sensor. The active optical element, such as a tunable liquid crystal lens, receives an electrical signal from the camera device via electrical conductors integral with the lens enclosure that provide electrical pathways between the active element on the interior of the enclosure and surface contacts on the camera device. The enclosure may be a two-piece structure, and the electrical conductors may be attached to either piece of the structure. The lens enclosure may also be threaded for attachment to the camera device. The electrical conductors may also use spring loaded contact portions or molded interconnect devices. | 04-19-2012 |

| 20110181797 | WAFER-LEVEL FABRICATION OF LIQUID CRYSTAL OPTOELECTRONIC DEVICES - Liquid crystal optoelectronic devices are produced by fabricating a wafer-level component structure and affixing a plurality of discrete components to a surface structure prior to singulating the individual devices therefrom. After singulation, the individual devices include a portion of the wafer-level fabricated structure and at least of the discrete components. The wafer-level structure may include a liquid crystal and controlling electrodes, and the discrete components may include fixed lenses or image sensors. The discrete components may be located on either or both of two sides of the wafer-level structure. Multiple liquid crystal layers may be used to reduce nonuniformities in the interaction with light from different angles, and to control light of different polarizations. The liquid crystal devices may function as optoelectronic devices such as tunable lenses, shutters or diaphragms. | 07-28-2011 |

| 20090295613 | PERFORMING ANALOG-TO-DIGITAL CONVERSION BY COMPUTING DELAY TIME BETWEEN TRAVELING WAVES IN TRANSMISSION LINES - A method and device for converting an analog input electrical signal to a digital signal. A plurality of integrated active and/or passive transmission lines may be implemented with signal-dependant propagation velocities. The delay differences of pulses traveling through these transmission lines are compared, and the collective results are used to evaluate and subsequently quantize the input signal. | 12-03-2009 |
| 20110215881 | Electrical Prism: A High Quality Factor Filter for Millimeter-Wave and Terahertz Frequencies - Filters and methods which may be used with millimeter-wave and terahertz frequency range are disclosed. The filter is formed as an electrical prism which may include a first lattice forming an interface with a second lattice. Each lattice may include a plurality of passive elements, such as inductors, capacitors, and the like. The first lattice may include an input disposed at an input boundary thereof, while the second lattice may include an output disposed at an output boundary thereof. Furthermore, the first and second lattices may be configured to receive a signal at the input of the first lattice, propagate the signal to the interface, and direct the signal to the outputs of the second lattice. | 09-08-2011 |
| 20120075034 | DOPPLER-INSPIRED, HIGH-FREQUENCY SIGNAL GENERATION AND UP-CONVERSION - Doppler-inspired methods for signal generation and frequency up-conversion are provided that are compatible with CMOS technology. In accordance with an embodiment, a circuit is provided that includes two input signals that can propagate on artificial transmission lines in opposite directions, resembling the relative movement of source and observer in Doppler frequency shift; and an output signal combiner. By controlling the characteristics of the transmission lines and the input signal frequencies, the harmonic generation of active devices is utilized and combined to provide the desired high-frequency component at the output. | 03-29-2012 |

| 20090096554 | 2D TRANSMISSION LINE-BASED APPARATUS AND METHOD - A power combiner comprising an LC lattice structure is shown, together with a method for generating a planar wave front. The LC structure can comprise constant or voltage dependent capacitors. Either the delay or the characteristic impedance of the two-dimensional transmission line formed by the LC lattice structure are kept constant. A planar wave propagating along one direction of the transmission line gradually experiences higher impedances at the edges, creating a lower resistance path for the current in the middle. This funnels more power to the center as the wave propagates. | 04-16-2009 |

| 20110194324 | Generation of High-Frequency, High-Power Electrical Signals From Low-Frequency, Low-Power Lattice Network Structures as Sources - An apparatus and method for outputting high-frequency, high-power signals from low-frequency, low-power input is disclosed. The apparatus and method may provide a two-dimensional nonlinear lattice having a plurality of inductors and voltage-dependent capacitors intersecting at a plurality of nodes. Two or more adjacent boundaries of the nonlinear lattice may be provided with input signals which constructively interfere to output a signal of substantially higher amplitude and higher frequency than those of the input signals. | 08-11-2011 |
