This project develops and evaluates the feasibility of a client-server application that integrates accessible life management tools for individuals with disabilities and those who support them in residential environments to improve the independent living capacity of persons with cognitive disabilities. A common database of information about an individual’s life and needs is developed providing r ...

There is a need for a high-resolution two-dimensional focal plane array (FPA) with single photon sensitivity (SPS), pulse amplitude storage, and GHz bit rates that can record both the time (with 10 bits) from multiple returns from a single laser pulse. Such a system has the potential to significantly reduce LADAR size, weight, and power (SWAP) by alleviating the laser requirements. In this program ...

New, modular radiation hard [>300 kRad (Si)] ROIC designs are required to address the needs of planned ballistic missile defense system. Anticipating the needs for large formats, small pixel sizes, and multiple spectral bands, the features of an existing radiation-hard space imager ROIC will be used to develop the design of an extensible 1024 × 1024, 15-μm pixel ROIC design. The design includes ...

Future seekers of the future will need to allow for multiple targets and various advanced countermeasures, likely including a dual-mode component to do so. A Dual Mode Seeker (DMS) has at least an infrared (IR) Focal Plane Array (FPA) as well as an active means to capture target range and preferably 3-D imagery. Future technology insertion will benefit from a monolithic dual mode focal plane, wher ...

A back-illuminated planar InGaAs photodiode tested to have 95% quantum effiiency (QE) at 1550 nm, area greater than 1 mm2, low capacitance (125 MHz) will be improved. Although the existing Phase I device exhibited bulk material dark current generation better than commercially available devices, the sidewall-generated dark current was found to dominate the noise equiva ...

A 128 x 128-format avalanche photodiode (APD) focal plane array (FPA), including a low-power dual-mode readout integrated circuit (ROIC) and low excess noise, high gain (M>1,200) will be developed for laser radar (LADAR) applications requiring reduced SWAP. The FPA gives LADAR seekers an advanced active tracking sensor capability, providing a sufficiently wide field of regard (FOR) to eliminate th ...

This project has two goals: (1) to develop and evaluate the feasibility of intelligent, computer-based self-management and household management applications that would improve the independent living capacity of persons with cognitive disabilities, and (2) to identify an agenda for full development of a deployable system in a Phase 2 project. Intelligent multimedia computer agents offer an untapped ...

Based on previous research, this project (1) refines the TV Assisted Prompting (TAP)system hardware and software while expanding its utility to new rehabilitation domains; and (2)continues to employ an incremental design process, partnering with patients, care providers, andtherapists to design and evaluate a user-friendly system. The TV Assisted Prompting (TAP) systemoffers a simple alternative f ...

We propose to develop Open Service Gateway Initiative (OSGi) enhancements for configuration management and validation to enable assured switching between operational and test modes. We will design a moded configuration management and validation suite that extends public-domain OSGi implementations with capabilities for trusted bundles, XML-based device inventories, and mode switching and configura ...

Voxtel proposes to develop fiber-coupled near-infrared avalanche photodiode (APD) receivers with photon detection efficiency (PDE) and dark count rate (DCR) with more than two orders of magnitude faster maximum count rate (MCR) than Geiger-mode APDs, which are constrained by a fundamental tradeoff between DCR and MCR: if the APD is cooled to reduce DCR, then its dead time must increase to avoid af ...
