| 20100046198 | Flexible Backlit Display - The present invention is directed toward a graphics display assembly configured to display a true color palette in illuminated and non-illuminate states. The graphics display assembly includes a backlit electroluminescent (EL) panel and optical interface layer. The optical interface layer is translucent, preventing color shift of transmitted light. In operation, the optical interface layer masks the pink or rose-colored hue visible when the EL panel is in its non-illuminated state. | 02-25-2010 |

| 20090240612 | Life Insurance Cooperative - A business method and computing system for providing a death benefit to a participant having an uninsurable trait. The method collects registration information from the participant, and associates the participant with at least one other participant having the uninsurable trait to form a group of participants. The method receives a funding payment from each participant in the group to create a funding pool for a time period. The method disburses the funding pool to deceased participants in the group who died during the time period, each deceased participant receiving a portion of the funding pool. An amount of the portion of the funding pool for each deceased participant is the death benefit for the deceased participant. | 09-24-2009 |

| 20100020832 | WAVELENGTH SELECTABLE LASER SYSTEMS AND RELATED METHODS - Laser systems and related methods are provided. In this regard, a representative laser system includes: a laser diode array that generates light; a first crystal having a cavity; an optical element operative to focus the generated light onto the first crystal such that the light generates a high-power circulating beam within the cavity; a second crystal positioned with respect to the first crystal such that the frequency of the high-power circulating beam is doubled; and a first coating applied to the first crystal and second coating applied to the second crystal, the first coating and the second coating being operative to cause at least a portion of the beam to be emitted within a particular wavelength range of the generated light. | 01-28-2010 |
| 20100020836 | USE OF CURRENT CHANNELING IN MULTIPLE NODE LASER SYSTEMS AND METHODS THEREOF - Current channels, blocking areas, or strips in a semiconductor laser are used to channel injected current into the antinodal region of the optical standing wave present in the optical cavity, while restricting the current flow to the nodal regions. Previous devices injected current into both the nodal and antinodal regions of the wave, which is fed by the population inversion created in the active region by the injected electrons and holes, but inversion created in the nodal regions is lost to fluorescence or supports the creation of undesirable competing longitudinal modes, causing inefficiency. Directing current to the antinodal regions where the electric field is at its maximum causes a selected longitudinal mode to preferentially oscillate regardless of where the longitudinal mode lies with respect to the gain curve. In one embodiment, exacting fabrication of the Fabry-Perot cavity correlates the current channels to antinodal regions, vis-a vis current blocking areas, strips or segmented layers. | 01-28-2010 |
| 20100102204 | ACTIVE OPTICAL LIMITING SEMICONDUCTOR DEVICE AND METHODS - An optical switching system comprising an embodiment with a high pass filter operable to eliminate a portion of frequencies present in an image and an optical device operative to receive the spectrally modified image from the high pass filter, alternatively amplify the spectrally modified image, and propagate at least those frequency components in the spectrally modified image exhibiting a frequency less than an absorption frequency of the optical switching device when the optical switching device is active. Alternatively, the optical switching system may transmit an image only when the system is active. The optical switching system may, for example, comprise superluminescent light emitting diodes which may be, for example, formed in the shape of an inverted truncated prism. For human viewing purposes, the operative transmission ranges may closely coincide with the maximum sensitivity of the photopic response of the corresponding red, blue and green cones in human eyes. | 04-29-2010 |
| 20100111124 | PUMPED SEMICONDUCTOR LASER SYSTEMS AND METHODS - A method for emitting laser radiation includes: emitting first laser radiation using a first laser, wherein said first laser is a laser diode; receiving the first laser radiation by a second laser comprising CdSe | 05-06-2010 |
| 20100321756 | Large Aperture Polymer Electro-Optic Shutter Device and Method of Manufacturing Same - A large-aperture direct-view high-speed electro-optic shutter includes an electro-optic polymer material constructed to form a Pockels cell and an integrated photoconducting semiconductor switch. A chromophore-doped polymer material or chromophore copolymer, wherein the chromophore is oriented within the polymer material, exhibits a linear electro-optic effect when an electric field is applied to the device. In one embodiment, the polymer host material comprises one or more of a polycarbonate, amorphous polycarbonate, or polymethylmethacrylate polymer hosts. The optically active chromophore comprising one or more coumarin and coumarin derivatives, stilbene or tolane derivatives is incorporated within the polymer host, forming a guest-host polymer. In another embodiment, the chromophore is chemically bonded to the monomer that forms the polymer, resulting in an optically active copolymer. The electro-optic shutter device is then activated by incident light through the photoconducting semiconductor switch, rendering the Pockels cell to have an optical density of at least 3.0. | 12-23-2010 |

| 20090172933 | PNEUMATIC CRIMPING TOOL - A crimping tool includes an anvil having a crimping surface containing at least one channel and a clamp having a crimping surface containing at least one channel arranged opposite the anvil crimping surface. The clamp is displaceable between an open position where the clamp is spaced from the anvil and a closed position where the clamp abuts the anvil with the crimping surfaces being arranged in contiguous relation and the channels being arranged opposite each other. A drive mechanism displaces the clamp between the open and closed positions. When a fastener is arranged in the anvil channel and the clamp is displaced to the closed position, the fastener is compressed in the clamp and anvil channels to fasten a fishing line or other element therein. | 07-09-2009 |
