The new concept of coupled dynamic dynamic-range (D<super>2</super>R) compositing operates by assembling sensor information, such as images or audio, from multiple "strong" and "weak" samplings or sensor snapshots, whose sensitivities drift and change over time, as lighting conditions or sound conditions change over time in their amplitude-domain properties. The authors...
A next-generation mass transportation system, consisting of TransPod aerospace vehicles designed to carry passengers at speeds exceeding 1000 km/h, is presented with respect to dynamics considerations. This system is based on electromagnetic propulsion of vehicles within a protected tube guideway, whose air pressure is reduced and controlled for improved performance at high speed. The tube environment...
We introduce the concept of coupled dynamic dynamic-range (D2R) compositing – that is, assembling sensor information, such as images or audio, from multiple dynamic-ranges that are allowed to move and change over time, as lighting conditions or sound conditions change over time in their amplitude-domain properties. We propose a feedback-control method to automatically adjust multiple exposure-value...
We introduce a multidimensional space to quantify a signal or sensor, expressed in three sets of dimensions: the physical space-time domain, the Fourier space-time domain, and the amplitude domain. When combined with veillametrics we can measure a sensor’s capacity-to-sense, as that capacity-to-sense propagates through space. Physical-Fourier-Amplitude visualizations can be generated for sensors,...
We propose a method to automatically adjust multiple exposure-value settings for HDR video compositing. The method uses imagespace-to-lightspace post-conversion and tonal extrapolation to iteratively select optimal exposure settings, as opposed to present systems, which use manually set settings. The limiting factor becomes the image sensor as opposed to the implementation of the algorithm, as in...
A novel class of modulation is introduced, for frequency transformation and spectral synthesis in real-time. Swarm modulation has potential applications to enhance human hearing with extended frequency ranges, in medical diagnostics for electrocardiogram (ECG), electroencephalogram (EEG) and other medical signals, for RADAR analysis, for user-interface sonification, and for sound synthesis or non-synthetic...
A core problem humanity faces today — underlying failing economies and governments, widespread corruption, and systems interoperability disasters — comes from a lack of integrity. We live in a world where organizations seek to know everything about us, yet reveal substantially nothing about themselves. This is a world of hypocrisy, which is the opposite of integrity. Hypocrisy is evident in entities...
We measure and visualize the ability-to-see, from the human eye, as that ability-to-see propagates through space. "Biological veillance flux" is a metric of sensory precision emitted from the eyes and falling on objects, with much greater detail than merely tracking the center of the eye's field of view. This work makes it possible to "see sight" and "measure sight" as...
We propose a highly expressive input device having keys that each generate an acoustic sound or similar disturbance when struck, rubbed, or hit in various ways. A separate acoustic pickup is used for each key, and these pickups are connected to a computer having an array of analog inputs. Non-binary, continuous sensitivity allows a smooth ("fluid") range of control. We describe three embodiments...
The light-bulb idea metaphor (a light bulb above someone's head that appears or switches on when they think of an idea) is widespread in the literature and popular culture. But, to the best of our knowledge, nobody has ever built an actual device that implements this function. Therefore we present the "Inventometer", a fun and playful wearable device that measures and displays epiphanometric...
We present "SqueaKEYS", a musical instrument application to enhance touch screens on mobile devices. Sound is generated acoustically by the sound of one or more fingers rubbing on the glass surface of a liquid crystal display screen, or the like. In this sense, the instrument is not an electronic instrument, but, rather, a friction idiophone (e.g. in the Hornbostel Sachs musical instrument...
We present a system that measures veillance flux, the ability of a camera to see, as the flux propagates through space. By wearing a veillance-integrating device, individuals are given an accumulated dosage readout based on their presence or absence in the veillance field of various cameras. The dose readout can be used as a score for players in an image-capture gaming environment, and as a means...

Actergy, the time-integral of energy, is employed in a human kinetic sensing system. This paper presents hardware and signal-processing mathematics to measure actergy in a health science, training or gaming environment, as a more detailed metric of performance than reflex time-delay. Fundamental quantities of Integral-Kinematics are compared alongside actergy, with further potential applications in...
A 3-dimensional augmediated reality (AR) environment was designed, where users can physically walk through space, and by looking through AR glasses can see and interact with hidden veillance flux produced by cameras. Surveillance cameras, physically attached to a room, as well as handheld and body-worn cameras, each emit veillance flux and have a veillance field — a mathematical formulation of their...
High Dynamic Range (HDR) compositing is well established in the field of image processing, where a sequence of differently-exposed images of the same scene are combined to overcome the limited dynamic range of ordinary cameras. We extend this technique to audio. Rather than acquiring samples separated by time or space, as is done in HDR image processing, we propose to perform simultaneous sampling...
We propose a hydraulic user interface consisting of an array of spray jets and the appropriate fluid sensing and fluid flow control systems for each jet, so that the device functions as a fluid-based tactile user interface. Our array of fluid streams work like the keys on a keyboard, but where each fluid stream can also provide tactile feedback by dynamically modulating the pressure of the fluid spray,...
A novel induction motor drive system has been designed for electric vehicles. The drive's speed controller includes an augmented proportion-integration (PI) control which increases drive efficiency and enhances overload protection. The augmented PI speed control is simply a traditional PI control with signal paths additively influenced by two new signals. These two new signals force the PI control...
