Ironically people who are blind or have visual impairments that should benefit the most from technology, have great difficulty in interacting with modern home appliances and electronics. This is primarily due to a combination of a lack of accessible features, device complexity, or the lack of a centralized strategy. Current strategies do not incorporate reminders, the possible fixed income status ...

Bridger Photonics Inc. (Bridger) proposes to develop the most compact, efficient and low-cost ultra-violet ozone differential absorption lidar (DIAL) transmitter available. This system will use a frequency-doubled, conductively-cooled, q-switched Nd:YAG laser to pump a combination optical parametric oscillator (OPO) and sum frequency generation (SFG) cavity to deliver 6 ns, 1.5 mJ and 1 kHz puls ...

This SBIR Phase I effort proposes to establish the feasibility of leveraging advances in compact laser technology with integration of space qualified techniques into AdvR's Planar Lightwave Circuit (PLC) and iodine reference cell technology for the design of a space qualifiable, frequency stabilized seed laser system in support of NASA Langley's High Spectral Resolution Lidar (HSRL) pr ...

Icing is a significant aviation hazard, and icing conditions continue to be difficult to precisely forecast or locate in real time. An in-situ sensor, which can be flown coupled with a radiosonde, is needed which can both measure supercooled liquid water content in clouds as well as characterize the droplet sizes. This sensor will support the calibration and validation of remote-sensing methods ...

The proposed optical device is a fiber-based multi-channel switch to quickly switch a fiber-coupled laser among many possible output channels to create a fiber-based fixed-array laser transmitter for next-generation NASA lidar systems. The key innovation is the use of an arrangement of electro-optic prisms created in a nonlinear optical crystal through domain reversal to direct the laser into one ...

Various technologies available to space system designers that operate at different voltage levels. It is, however, important to interface, maintain, and update these systems. For example, the Sun Earth Connection (SEC) missions are likely to have a variety of experiments needing to be accomplished with a single nanosatellite. A rad-hard reconfigurable bi-directional level shifters would allow th ...

The SSC needs a hydrogen temperature sensor that can provide high accuracy, fast response and can be operated on a superheated hydrogen (SHH2) environment. This will help prepare the SSC testing facility to support the new NASA mission for US space exploration as proposed by the President in January 2004. Here, we propose to develop an innovative, non-intrusive temperature sensor based on Spontan ...

The proposed SBIR effort will employ a systems approach to develop motor/controller/screw element systems adequate for demanding launch thrust vector control and control surface actuator applications. This approach will utilize high bandwidth, high efficiency, redundant motor systems coupled with appropriately paired motor controls. The actuator system will consist of a high efficiency permanen ...

Resodyn Technologies proposes a new technology that enables the application of polyimide based cryogenic insulation with low hydrogen permeability. This effort supports the Vision for U.S. Space Exploration policy and the Exploration Systems Enterprise. This technology will benefit designers of cryogenic fuel tanks envisioned for new Earth-to-Orbit (ETO) Transportation vehicles. Specifically th ...

The availability of remotely sensed data has been improving with each new high-resolution satellite obtaining operational capability in orbit. However, the ability of commercial and government entities to efficiently share or sell this data has not kept pace. The proposed GeoSpatial data distribution system will exploit recent improvements in advanced computing environments and processing algorit ...
