Emergency-escape device
Relatively simple inexpensive device uses reeled steel cable, is controlled by automotive-type shock absorber, and allows safe descent from burning building. Device is cheap to manufacture and assemble and requires neither skill, special knowledge, or athletic ability to operate. It is reliable and fireproof and can be deployed instantly
Female Genital Mutilation: Exploring Strategies for Ending Ritualized Torture; Shaming, Blaming, and Utilizing the Convention against Torture
The intent of this article is to graphically describe female genital mutilation (FGM); discuss the background of FGM and its health, psychological, and social implications; propose some workable solutions to ending FGM; and raise the level of awareness of the pain and suffering of women around the world. In part, this article will discuss invoking the Convention against Torture against those nations unwilling to end this horrific practice. There is also a caveat to this article: the author acknowledges that discussing solutions to the practice of FGM is not a simplistic and straight-forward endeavor. Solutions to ending FGM are as complicated as the societies that practice it. Therefore, ending FGM cannot be reduced to feel-good sound bites, but must be thoughtful, respectful, and deliberate
An inexpensive vehicle speed detector
Low-power minicomputer can plug into automobile cigarette lighter. It measures time it takes observed car to travel premeasured distance and provides immediate readout of speed. Potentially, detector could be manufactured for less than $200 per unit and would have very low maintenance cost
The Influence of Social Priming on Speech Perception
Speech perception relies on auditory, visual, and motor cues and has been historically difficult to model, partially due to this multimodality. One of the current models is the Fuzzy Logic Model of Perception (FLMP), which suggests that if one of these types of speech mode is altered, the perception of that speech signal should be altered in a quantifiable and predictable way. The current study uses social priming to activate the schema of blindness in order to reduce reliance of visual cues of syllables with a visually identical pair. According to the FLMP, by lowering reliance on visual cues, visual confusion should also be reduced, allowing the visually confusable syllables to be identified more quickly. Although no main effect of priming was discovered, some individual syllables showed the expected facilitation while others showed inhibition. These results suggest that there is an effect of social priming on speech perception, despite the opposing reactions between syllables. Further research should use a similar kind of social priming to determine which syllables have more acoustically salient features and which have more visually salient features
Investigation, development, and application of optimal output feedback theory. Volume 3: The relationship between dynamic compensators and observers and Kalman filters
Relationships between observers, Kalman Filters and dynamic compensators using feedforward control theory are investigated. In particular, the relationship, if any, between the dynamic compensator state and linear functions of a discrete plane state are investigated. It is shown that, in steady state, a dynamic compensator driven by the plant output can be expressed as the sum of two terms. The first term is a linear combination of the plant state. The second term depends on plant and measurement noise, and the plant control. Thus, the state of the dynamic compensator can be expressed as an estimator of the first term with additive error given by the second term. Conditions under which a dynamic compensator is a Kalman filter are presented, and reduced-order optimal estimaters are investigated
Optical tracking mount Patent
Tracking mount for laser telescope employed in tracking large rockets and space vehicles to give information regarding azimuth and elevatio
Algorithms for output feedback, multiple-model, and decentralized control problems
The optimal stochastic output feedback, multiple-model, and decentralized control problems with dynamic compensation are formulated and discussed. Algorithms for each problem are presented, and their relationship to a basic output feedback algorithm is discussed. An aircraft control design problem is posed as a combined decentralized, multiple-model, output feedback problem. A control design is obtained using the combined algorithm. An analysis of the design is presented
Technique for improving hydrodynamic gyro bearings
Conical or spherical, spirally grooved grease bearings have an inclined surface which is machined inboard of the grooved surface. The indentation and inclined surface provide a reservoir for forced out lubricant, and when rotation begins, centrifugal force returns the lubricant to the grooved area
