A key component of interacting with the world is how to direct ones’ sensors so as to extract task-relevant information — a process referred to as active sensing. In this review, we present a framework for active sensing that forms a closed loop between an ideal observer, that extracts task-relevant information from a sequence of observations, and an ideal planner which specifies the actions th...

Sequences having better autocorrelation properties play a crucial role in enhancing the performance of active sensing systems. Hence, sequences with good are very much demand. In this paper, we addressed problem designing unimodular sequence side-lobe levels. We formulated it as constrained optimization comprising Integrated Side-lobe Level (ISL) metric and then proposed an effective algorithm ...

Most distributed sensing methods assume that the expected value of sensed information is same for all agents – ignoring differences in sensor capabilities due to, for example, environmental factors and sensors’ quality and condition. In this paper, we present a distributed sensing framework to exploit heterogeneity in information provided about a dynamic environment using an active-passive netw...

Discovering the three dimensional structure of an object is important for a variety of robot tasks. Single sensor systems such as machine vision systems cannot reliably compute three dimensional structure in unconstrained environments. Active, exploratory tactile sensing can be used to complement passive stereo vision data to derive robust surface and feature descriptions of objects. The contro...

Scientists with NASA’s Earth Science Applications Directorate are creating a well-characterized Verification &Validation (V&V) site at the Stennis Space Center (SSC). This site enables the in-flight characterization of remote sensing systems and the data that they acquire. The data are predominantly acquired by commercial, high-spatial resolution satellite systems, such as IKONOS and QuickBird ...

Traditional local active noise control systems minimise the measured acoustic pressure to generate a zone of quiet at the physical error sensor location. The resulting zone of quiet is generally limited in size and this requires the physical error sensor be placed at the desired location of attenuation, which is often inconvenient. To overcome this, a number of virtual sensing algorithms have b...

The future of Intelligent Transportation Systems is intertwined with the development, implementation, and penetration of distributed sensing and communications networks. We propose a general, cooperative, holistic active safety framework, LACASA, that can make immediate and significant impacts on safety as part of a stand-alone driver assistance systems in vehicles. The cooperative modularity o...

The ubiquitous trend toward miniaturized sensing systems demands novel concepts for compact and versatile spectroscopic tools. Conventional optical sensing setups include a light source, an analyte interaction region, and a separate external detector. We present a compact sensor providing room-temperature operation of monolithic surface-active lasers and detectors integrated on the same chip. T...
