Point-of Care (POC) devices that can perform multi-step processes, are easy to use, and are inexpensive, are needed for use in limited-resource settings. We present an integrated paper-based device that performs an automated immunoassay for the detection of IgM antibodies with on-board sample processing. The device is a two-dimensional paper network (2DPN) consisting of protein-G coated nitroce...

The Data Management System (DMS) is the information and communications system on-board Space Station Freedom. Extensive modeling of the DMS is being conducted throughout NASA to aid in the design and development of this vital system. In this paper we discuss activities at NASA Ames Research Center to model the DMS network infrastructure, focusing on modeling of the Fiber Distributed Data Interf...

This paper reports on work carried out in the project Vehicle Model Based Diagnosis (VMBD ), funded through the BriteEuRam III programme of the European Commission. The project aims at demonstrating the utility of model-based diagnosis for real automotive problems both in on-board and off-board situations by installing suitable systems on demonstrator vehicles. The paper presents the results ob...

The paper presents an on-board estimation, navigation and control architecture for multi-rotor drones ying in urban environment. It consists of adaptive algorithms to estimate vehicle's aerodynamic drag coe cients with respect to still air and the urban wind components along the ight trajectory, with guaranteed fast and reliable convergence to the true values; navigation algorithms to generate ...

We investigate how the contractibility of actions affecting the value of an asset affects asset ownership. We examine this by testing how on-board computer (OBC) adoption affects truck ownership. We develop and test the proposition that adoption should lead to less ownership by drivers, particularly for hauls where drivers have the greatest incentive to drive in non-optimal ways or engage in re...

In 2013 the Alphasat spacecraft will be launched: in addition to its main commercial payload, four Technology Demonstration Payloads (TDPs) will fly on-board. The different payloads are provided by different research institutes, which will be able to define in-orbit demonstration tests of these new technologies. To optimize this opportunity, coordination of the different, possibly conflicting, ...

This paper presents the application of an evolutionary technique to lane markings detection in road environments. The aim is the localization of the path in images acquired by a vision system installed on-board of a vehicle for driving assistance or automation purposes. The first step of the procedure is the removal of the perspective effect from the images. The resulting bird’s eye view image ...

In this paper we present an open robotic platform which is targeted to perform the task of a tennis ball boy. Our platform can localize itself and navigate on a tennis court. It can also localize tennis balls lying on the court. It is self-contained with on-board sensing and computation, uses only cost-effective off-the-shelf components, and was designed with an eye for robustness and repeatabi...

With respect to the long-life missions associated with NASA’s X2000 Advanced Deep-Space System Development Program, reliability implies a system’s continuous operation for many years in an unsurveyed radiation-intense environment. Further, the stringent constraints on the mass of a spacecraft and the power on-board create unprecedented challenges on the means for achieving the ultra-high missio...

We describe a system of small wireless autonomous mobile cameras that operate as a group to solve machine vision tasks. Given sufficient on-board computing to do realtime scene analysis without external processing resources, these cameras enable us to investigate how scene understanding can be improved when each camera is independently capable of analyzing its own sensor data, and sharing infor...
