The NASA SBIR product catalog

The purpose of this catalog is to assist small business firms in making the community aware of products emerging from their efforts in the Small Business Innovation Research (SBIR) program. It contains descriptions of some products that have advanced into Phase 3 and others that are identified as prospective products. Both lists of products in this catalog are based on information supplied by NASA SBIR contractors in responding to an invitation to be represented in this document. Generally, all products suggested by the small firms were included in order to meet the goals of information exchange for SBIR results. Of the 444 SBIR contractors NASA queried, 137 provided information on 219 products. The catalog presents the product information in the technology areas listed in the table of contents. Within each area, the products are listed in alphabetical order by product name and are given identifying numbers. Also included is an alphabetical listing of the companies that have products described. This listing cross-references the product list and provides information on the business activity of each firm. In addition, there are three indexes: one a list of firms by states, one that lists the products according to NASA Centers that managed the SBIR projects, and one that lists the products by the relevant Technical Topics utilized in NASA's annual program solicitation under which each SBIR project was selected

Index to 1981 NASA Tech Briefs, volume 6, numbers 1-4

Short announcements of new technology derived from the R&D activities of NASA are presented. These briefs emphasize information considered likely to be transferrable across industrial, regional, or disciplinary lines and are issued to encourage commercial application. This index for 1981 Tech Briefs contains abstracts and four indexes: subject, personal author, originating center, and Tech Brief Number. The following areas are covered: electronic components and circuits, electronic systems, physical sciences, materials, life sciences, mechanics, machinery, fabrication technology, and mathematics and information sciences

Holographic reality: enhancing the artificial reality experience throuhg interactive 3D holography

Holography was made know by several science-fiction productions, however this technology dates back to the year 1940. Despite the considerable age of this discovery, this technology remains inaccessible to the average consumer. The main goal of this manuscript is to advance the state of the art in interactive holography, providing an accessible and low-cost solution. The final product intends to nudge the HCI com munity to explore potential applications, in particular to be aquatic centric and environmentally friendly. Two main user studies are performed, in order to determine the impact of the proposed solution by a sample audience. Provided user studies include a first prototype as a Tangible User Interface - TUI for Holographic Reality - HR Second study included the Holographic Mounted Display - HMD for proposed HR interface, further analyzing the interactive holographic experience without hand-held devices. Both of these studies were further compared with an Augmented Reality setting. Obtained results demonstrate a significantly higher score for the HMD approach. This suggests it is the better solution, most likely due to the added simplicity and immersiveness features it has. However the TUI study did score higher in several key parameters, and should be considered for future studies. Comparing with an AR experience, the HMD study scores slightly lower, but manages to surpass AR in several parameters. Several approaches were outlined and evaluated, depicting different methods for the creation of Interactive Holographic Reality experiences. In spite of the low maturity of holographic technology, it can be concluded it is comparable and can keep up to other more developed and mature artificial reality settings, further supporting the need for the existence of the Holographic Reality conceptA tecnologia holográfica tornou-se conhecida através da ficção científica, contudo esta tecnologia remonta até ao ano 1940. Apesar da considerável idade desta descoberta, esta tecnologia continua a não ser acessíveil para o consumidor. O objetivo deste manuscrito é avançar o estado de arte da Holografia Interactiva, e fornecer uma solução de baixo custo. O objetivo do produto final é persuadir a comunidade HCI para a exploração de aplicações desta tecnologia, em particular em contextos aquáticos e pró-ambientais. Dois estudos principais foram efetuados, de modo a determinar qual o impacto da solução pro posta numa amostra. Os estudos fornecidos incluem um protótipo inicial baseado numa Interface Tangível e Realidade Holográfica e um dispositivo tangível. O segundo estudo inclui uma interface baseada num dispositivo head-mounted e em Realidade Holográfica, de modo a analisar e avaliar a experiência interativa e holográfica. Ambos os estudos são comparados com uma experiência semelhante, em Realidade Aumentada. Os resultados obtidos demonstram que o estudo HMD recebeu uma avaliação significante mel hor, em comparação com a abordagem TUI. Isto sugere que uma abordagem "head-mounted" tende a ser melhor solução, muito provavelmente devido às vantagens que possui em relação à simplicidade e imersividade que oferece. Contudo, o estudo TUI recebeu pontuações mais altas em alguns parâmetros chave, e deve ser considerados para a implementação de futuros estudos. Comparando com uma experiência de realidade aumentada, o estudo HMD recebeu uma avaliação ligeiramente menor, mas por uma margem mínima, e ultrapassando a AR em alguns parâmetros. Várias abordagens foram deliniadas e avaliadas, com diferentes métodos para a criação de experiências de Realidade Holográfica. Apesar da pouca maturidade da tecnologia holográfica, podemos concluir que a mesma é comparável e consegue acompanhar outros tipos de realidade artificial, que são muito mais desenvolvidos, o que suporta a necessidade da existência do conceito de Realidade Holográfica

Holographic memory using beam steering

A method, apparatus, and system provide the ability for storing holograms at high speed. A single laser diode emits a collimated laser beam to both write to and read from a photorefractice crystal. One or more liquid crystal beam steering spatial light modulators (BSSLMs) steer a reference beam, split from the collimated laser beam, at high speed to the photorefractive crystal

NASA SBIR abstracts of 1991 phase 1 projects

The objectives of 301 projects placed under contract by the Small Business Innovation Research (SBIR) program of the National Aeronautics and Space Administration (NASA) are described. These projects were selected competitively from among proposals submitted to NASA in response to the 1991 SBIR Program Solicitation. The basic document consists of edited, non-proprietary abstracts of the winning proposals submitted by small businesses. The abstracts are presented under the 15 technical topics within which Phase 1 proposals were solicited. Each project was assigned a sequential identifying number from 001 to 301, in order of its appearance in the body of the report. Appendixes to provide additional information about the SBIR program and permit cross-reference of the 1991 Phase 1 projects by company name, location by state, principal investigator, NASA Field Center responsible for management of each project, and NASA contract number are included
