Liquid-Crystal Blazed-Grating Beam Deflector

A transmission-type nonmechanical multiple-angle beam-steering device that uses liquid-crystal blazed grating has been developed. Sixteen steering angles with a contrast ratio of 18 has been demonstrated. A detailed analysis of the liquid-crystal and poly(methyl methacrylate) blazed-grating deflector was carried out to provide guidance during the deflector’s development. A manufacturing offset compensation technique is proposed to improve the device’s performance greatly. A hybrid approach utilizing electrically generated blazed grating combined with the cascading approach described here yields in excess of 500 deflecting angles

Product Launch in a Declining Environment: The Blu-ray Disc – Opportunities and Struggle

Increasingly ICT-based virtual products are challenging physical products and markets. Obsolescence has become a real effect for an augmented number of established industries due to the facilitation of access, consumption, and permanent, immediate availability, which dematerialised products provide. Once again, Schumpeter’s Wind of Creative Destruction intensifies organisations’ permanent struggle for survival (1950). This paper presents long-term research in the optical disc industry, which has presented the optical disc format of Blu-ray as its latest innovation. It is an example of how an established industry launches a new product for finding new opportunities, but fights desperately against market resistance. The degree of innovation, the Blu-ray represents, may not be sufficient in the overarching battle of the physical place versus the virtual space (Kotler et al. 2002, Lam. 2004, Lamont et al. 1993, Scardigli et al. 1988). As the US market research institute In-Stat highlights, the optical disc market has declined for the 10th year in sequence (Kaufhold. 2010, IFPI. 2010). Sufficient evidence is available that the replication industry of optical discs may be confronted with an endgame scenario. The market climate may already be too hostile to support this industry’s desire for a renewal of consumers’ acceptance of the physical product, here the Blu-ray disc, and to create new market opportunities in the struggle against the industry’s potential obsolescence (Harrigan et al. 1983). Despite strong efforts of promotion and powerful market approaches, the Blu-ray disc could not find inroads to markets yet making this format sustainably successful. Evidence is that after a short period of time, Blu-ray discs’ available manufacturing capacities outperform consumers’ demand by >30%, consumer and replication prices fall sharply and many of the Home Entertainment’s content providers have little or no use for this format being a commodity and based on mass production (dvd-intelligence. 2010a, Kaufhold. 2010, Killer-Korff. 2010). Therefore, as research among the replication industry indicates, it presently seems more as though the Blu-ray format may not fulfil this industry’s needs and, with reference to Abernathy et al.’s research, may not lead to the renewal of industrial dynamics in a declining marketplace (1983, 1984). Further explanation for reasons can be found in the theories of innovation based on Utterback’s, Christensen’s and Christensen et al.’s studies of disruptive and discontinuous innovation (1996, 2003, 2003, 2004). Following the paper presented at the Sixteenth Annual South Dakota International Business Conference, this paper presents research about the Blu-ray format’s market problems. The introduction of the Transilience Organisation Innovation Map provided a conceptual approach for the initial explanation of the underlying reasons (Oestreicher. 2009). Research among European replication firms since concludes for Blu-ray that innovation in technology alone is not sufficient, when innovation’s second stream of market linkages is involved (Abernathy et al. 1983, 1984). The paper presents explanations, why the Blu-ray disc may not be sufficiently strong to support the replication industry in overcoming the odds impacting their strategic opportunities in a declining and eventually disruptive environment (Lamont et al. 1993, Yoo. 1992). The research methods applied are grounded theory and case study (Goulding. 2002, Charmaz. 2009, Eisenhardt. 1989, Davies. 2006). The overall intention of this long-term research is to contribute to a theory, which may also be relevant for other industries, like the publishing industry, whose struggle against dematerialisation of content is presently starting (Picard. 2003). Key Words: Radical vs. marginal innovation, Ideal Final Result, endgame strategies, theories of innovation, Blu-ra

Configurational Information as Potentially Negative Entropy: The Triple Helix Model

Configurational information is generated when three or more sources of variance interact. The variations not only disturb each other relationally, but by selecting upon each other, they are also positioned in a configuration. A configuration can be stabilized and/or globalized. Different stabilizations can be considered as second-order variation, and globalization as a second-order selection. The positive manifestations and the negative selections operate upon one another by adding and reducing uncertainty, respectively. Reduction of uncertainty in a configuration can be measured in bits of information. The variables can also be considered as dimensions of the probabilistic entropy in the system(s) under study. The configurational information then provides us with a measure of synergy within a complex system. For example, the knowledge base of an economy can be considered as such a synergy in the otherwise virtual (that is, fourth) dimension of a regime

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

Holographic Optical Elements and Application

Holographic optical element has a high diffraction efficiency and a narrow-band frequency characteristic, and it has a characteristic that is able to implement several features in a single flat device. It is widely applied in various fields. In this chapter, the principle and characteristics of the holographic optical elements are described in detail, and few typical holographic optical element-based applications, such as head-mounted display, lens array, and solar concentrator, are introduced. Finally, the futuristic research concepts for holographic optical element-based applications and contents are discussed

The Effectiveness of Augmented Reality for Astronauts on Lunar Missions: An Analog Study

The uses of augmented reality and head-up displays are becoming more prominent in industries such as aviation, automotive, and medicine. An augmented reality device such as the Microsoft HoloLens can project holograms onto the user’s natural field of view to assist with completion of a variety of tasks. Unfortunately, only a little research and development has begun in the space sector for astronauts using these head-up displays. Future lunar missions could incorporate augmented reality for astronauts to ease task load and improve accuracy. This study evaluated the usability, subjective workload, and task performance of 22 participants using the Microsoft HoloLens to complete tasks that are analogous to those completed by astronauts on a lunar mission, including navigation, rock sample collection, and maintenance tasks. Results from the usability survey, NASA-TLX, and usability interview suggested that augmented reality could support astronaut missions by means of reduced workload and task errors. Usability data information collected from the participants sought to improve on the user interface and confirmed the aforementioned results. The researcher concluded that further research must be conducted to test the development of augmented reality interfaces along with the usability aspect by the National Aeronautics and Space Administration astronauts
