Tiny Camera Lets NASA Inspection Tool “See”

micro ScoutCam‘ 1.2 micro camera Medigus, Ltd. Omer, Israel 011 972 8646 6880 www.medigus.com NASA has incorporated the micro ScoutCam 1.2 into its Visual Inspection Poseable Invertebrate Robot (VIPIR) tool. VIPIR is a robotic, maneuverable, borescope inspection tool being tested as part of the Robotic Refueling Mission, an experiment on the International Space Station that has been demonstrating tools, technologies, and techniques for on-orbit satellite servicing since 2011.

Head-Worn Display Concepts for Ground Operations for Commercial Aircraft

This display enables a higher level of safety during ground operations, including taxiway navigation and situational awareness. Langley Research Center, Hampton, Virginia The Integrated Intelligent Flight Deck (IIFD) project, part of NASA’s Aviation Safety Program (AvSP), comprises a multi-disciplinary research effort to develop flight deck technologies that mitigate operator-, automation-, and environment-induced hazards. Toward this objective, the IIFD project is developing crew/vehicle interface technologies that reduce the propensity for pilot error, minimize the risks associated with pilot error, and proactively overcome aircraft safety barriers that would otherwise constrain the next full realization of the Next Generation Air Transportation System (NextGen). Part of this research effort involves the use of synthetic and enhanced vision systems and advanced display media as enabling crew-vehicle interface technologies to meet these safety challenges.

Flight Imagery Recorder Locator (FIRLo) and High-Temperature Radome

This technology is applicable to the commercial airline industry for locating “black boxes.” NASA’s Jet Propulsion Laboratory, Pasadena, California LDSD (Low Density Supersonic Decelerator) is a Mars EDL (entry, descent, and landing) Technology Development Project that launches three test vehicles out of the Pacific Missile Range Facility in Kauai. On the test vehicle, most mission science data can be recorded safely on land; however, high-speed and high-resolution imagery cannot be telemetered due to bandwidth constraints. Therefore, all information had to be recorded solely onboard the test vehicle; this unit is called the flight imagery recorder (FIR). A typical commercial airliner “black box” is only capable of recording on the order of gigabytes of data, whereas this work required on the order of terabytes (a few orders of magnitude larger).

Thermal Imaging’s Pocket-Sized Potential

Let’s say you’re a prospective buyer touring an older home that you suspect has some weatherization issues. What if you could verify your hunch by literally seeing cold air seeping under doors or cooling walls where insulation is missing? And what if you could do this on the spot using a smartphone?

Camera Considerations When Inspecting Printed Circuit Boards

PCB manufacturing is a very competitive market, and manufacturers must be able to confidently ship accurate printed circuit board (PCB) products. Delivery of incorrect boards may have a significant, negative impact on the company reputation, which can directly result in lost business. Inspection of the boards before shipment is required.

NASA's Hot 100 Technologies: Instrumentation

Powder Handling Device for Analytical Instruments This technology provides automated sample handling and movement of coarse-grained powder or other solid materials to enable analysis by a robotic or totally automated computer system. The powder is handled as a fluid, using mechanical vibrations in conjunction with a driving force, and requiring few or no moving parts.

NASA's Hot 100 Technologies: Optics

Automated Vision Test The traditional test for visual acuity requires the patient to look and report which letters they see. A new invention provides an automated system to estimate visual acuity based on objective measurements of the eye optics and wavefront aberrations. A typical measurement consists of a list of numbers that constitute the coefficients of the polynomials. The algorithm converts the list of numbers into an estimate of the visual acuity of the patient.

Prepping Advanced Driver Assistance for Mainstream Vehicles

Forward-facing cameras, integrated with vehicle controls, are being used to recognize pedestrians, signs, and other cars and motorcycles. Automatic brake mechanisms — often connected to a combination of radar, camera, and sensors — can halt a vehicle as it approaches an object ahead. New mounted cameras have the ability to register road markings and keep drivers within their own lanes.

Blurring the Boundaries: IP and Machine Vision Cameras Converge

In modern production facilities, users are more frequently combining two different strands of camera technology. Classic machine vision cameras manage inspection tasks and yield management, while network cameras (also called IP cameras) handle process monitoring and bringing production to a standstill when necessary.

Defining the Smart Camera

Smart cameras have been used in industrial applications for roughly two and a half decades, but advances in processor technologies have made the devices much more accessible and popular within the past 7 years, especially in areas such as machine vision and surveillance. However, when the term smart camera is mentioned, a wide variety of ideas still come to mind among individuals because there is no widespread agreement upon the definition of what a smart camera technically is. It is generally agreed upon that the basics of a smart camera include not only the image sensor, but also some type of processing chip: a CPU, DSP, FPGA, or other type of processing device (see Figure 1).
