A force feedback system, such as the haptic wheel used in the EECS 461 lab, is capable of exhibiting a wide range of interesting phenomena. It is useful to remember that the system consists of a mechanical device (the wheel in our case), with two feedback loops wrapped around it. As shown in Figure 1, one feedback loop consists of (i) a sensor such as an encoder, tachometer, or strain gauge, (i...

An experimental speech recognition system was developed for German using an already existing technology reported elsewhere (1). The system recognizes complete sentences when the words are spoken with a small pause in between. The user has to train the system in advance by uttering 110 short sentences. The size of the system's vocabulary is presently limited to about 1300 words, with a coverage ...

The ballista spring system is a simplified orthodontic system for treating impacted teeth. The impacted tooth is retracted by a spring that accumulates a continuous force from being twisted on its long axis. The necessary operation on the impacted tooth is simple and less traumatic. The force exerted on the tooth is vertical, without compressing the impacted tooth toward the adjacent roots. Thi...

The timing system of SPring-8 booster synchrotron generates various timing signals concerning beam injection, acceleration from 1 GeV to 8 GeV and ejection. We have improved the timing system of the synchrotron giving it better stability and flexibility. This improvement results the other merits of advanced operations, for example, storing electron beam in the synchrotron, changing the injectio...

In this paper, based on maximizing the outrigger-belt truss system’s strain energy, a methodology for determining the optimum location of an outrigger-belt truss system is presented. Tall building structures with combined systems of framed tube, shear core and outrigger-belt truss system’s are modeled using continuum approach. In this approach, the framed tube system is modeled as a cantilevere...

This paper presents how to design and implement a simple mass/spring system on a general-purpose topological structure. This way, topological inquiries or changes can be handled robustly so that the mesh remains consistent and a manifold.

An integrated platform which is capable of meeting requirements of both traditional real-time control processing and multimedia processing has enormous potential for accommodating various kinds of new applications. However, few, if any, research or commercial systems successfully provide architectural and OS mechanisms which can eeciently support both deterministic hard real-time computation an...

The simplest model possible for bouncing systems consists of a point mass bouncing passively on a mass-less spring without viscous losses. This type of spring-mass model has been used to describe the stance period of symmetric running gaits. In this study, we investigated the interaction between horse and rider at trot using three models of force-driven spring (-damper)-mass systems. The first ...

the present study is the first to analyze the dynamic response of a poroelastic beam subjected to a moving force. moreover, the influences of attached mass-spring systems and non-ideal supports (with local movements in the supporting points or base due to the presence of factors such as gaps, unbalanced masses, and friction or seismic excitations) on the responses were investigated. non-ideal s...

A fast and efficient deformation model is essential for realistic simulation of image morphing. In order to create models that are fast to simulation, we use a mass-spring system, which is applied widely in the real time animation of deformable objects. One-to-one deformation is one of the important issues in image morphing. We propose a method of detecting and removing overlaps in the process ...
