CMOS Cameras

SMARTEK Vision (New London, CT) offers the “twenty-nine” series of CMOS machine-vision cameras. Distributed by FRAMOS Technologies (Ottawa, Ontario, Canada), the 29 x 29- mm camera line fits GigE Vision and USB3 Vision with a high-speed sensor front-end into a miniature housing. Pixel sizes range from 5.86 μm and 3.45 μm down to 1.25 μm; sensor formats range from 1/2" to 1/3". The camera connects with C-Mount, Power-over-Ethernet (PoE), and general-purpose IOs (GPIO) via a 6-pin Hirose component.

Motorized Actuators

A new series of low-cost DC drive motors from Siskiyou Corporation (Grants Pass, OR) enables precise, hands-free adjustment of translation stages and mirror mounts, using a simple, push-button control pad. Specifically, the new 500 series actuators can replace manual screw and micrometer adjusters on Siskiyou’s crossed roller bearing linear stages, kinematic mirror mounts, and IS OGP beam steering assembly for microscopes. The hand-held controller for operating these actuators offers two preset drive speeds (0.3 mm/s and 0.1 mm/second), as well as an adjustable low speed range (from 10 μm/s to 30 μm/s). The latter enables consistent, small moves (down to 1.0 μm) with a single, short button press.

How to Manage Heat in Modular, COTS Enclosures

As components shrink, embedded systems have made their way into smaller and more mobile applications. Systems need to withstand more intense vibration, shock and EMI parameters and still function effectively. All of this affects the ruggedization of enclosures.

Tension Stiffened and Tendon Actuated Manipulator

This configuration offers mechanical advantage and improved efficiency over existing arms that use weighty gearboxes and motors.

Langley Research Center, Hampton, Virginia

NASA’s Langley Research Center is developing a robotic arm with lightweight joints that provide a wide range of motion. The envisioned design provides users with a long reach and numerous degrees of freedom. The arm, ideal for use in aquatic environments or for manipulation of light terrestrial loads, consists of articulating booms connected by antagonistic cable tension elements. The arm elements are structurally efficient and lightweight, and support compact packaging. The inherent mechanical advantage provided by the tendon articulation allows the use of small, efficient motor systems. The manipulator can be scaled over a large range from 10 m (load-bearing arm) to over 1000 m (submersible or float-supported arm). Current efforts are focusing on a 15-m prototype and a 300-m subsystem to test the unique robotic architecture. NASA is seeking partners to assist with the development of its concept system for specific applications.

Lattice Structures Coating Concept for Efficient Thermal Linking Beds

Marshall Space Flight Center, Alabama

Conventional air revitalization technology for removal of CO2, moisture, and trace organic contaminants usually involves a packed bed of sorbent pellets that can be regenerated using a concept similar to that of pressure swing adsorption (PSA). Additional heat input for thermal regeneration is preferred during the adsorption-desorption process to increase the regeneration efficiency. Typically, a pair of adsorber modules consisting of the same sorbent material with identical loading capacity is placed in parallel and work in tandem, where one module adsorbs the contaminants from the process air while the other is in regeneration mode. The two adsorber modules have separate housings and may be placed in separate locations.

A Statistically Based Approach to Broadband Liner Design and Assessment

The current method targets the entire broadband frequency spectrum simultaneously.

Langley Research Center, Hampton, Virginia

The broadband component of fan noise has grown in relevance with the utilization of increased bypass ratio and advanced fan designs. Thus, while the attenuation of fan tones remains paramount, the ability to simultaneously reduce broadband fan noise levels has become more attractive. Advanced manufacturing techniques have also opened new possibilities for the implementation of broadband liner concepts. This innovation is an integrated method for the design and evaluation of novel broadband acoustic liner concepts for complex engine configurations.

Connection and Repair Techniques for Capillary Tubing in Restrictive Areas and Gas Chromatography Applications

John F. Kennedy Space Center, Florida

Capillary columns offer challenges in gas chromatography (GC) work due to their small size and fragile nature. Typical repair techniques to join two capillary columns require cumbersome metal fittings. This solution is not applicable in all situations due to size and mass limitations. Another repair or joint technique involves the use of polyimide glue with a tapered glass union. Without the bulky glass fitting, this technique is difficult to perform without plugging the column; the low-viscosity glue wicks up the capillary column and fills the small opening of the joint. Polyimide is also a problem due to its hydrolysis when trying to analyze water; the polyimide glue interacts with the water in the sample and affects the analysis. These solutions don’t support a repair of capillary columns for water analysis in a small gas chromatograph module.

Product of the Month: August 2016

Hexagon Manufacturing Intelligence, North Kingstown, RI, introduced the BLAZE 600M non-contact optical measurement solution. The flexible, manually operated system provides ultra-rapid 3D data acquisition and actionable data for measurement, inspection, product development, line tuning, and reverse engineering. The scanner performs feature and surface measurements of parts and assemblies in various sizes, combining high-resolution digital imaging with blue light LED illumination, and does not require surface treatment of metallic, plastic, and composite parts. The system is not sensitive to industrial and ambient light sources or indirect daylight. It is designed for operation in high-vibration industrial environments. The all-in-one system is available in two projection configurations for tasks such as routine dimensional control operations or measurement of workpieces with complex features or challenging material types. Operators can also directly switch between surface data acquisition modes.

Measurement Terminal

The EL3751 EtherCAT terminal from Beckhoff Automation (Savage, MN) provides measurement as part of a standard I/O system. It acquires data at 10,000 samples per second and provides measurement accuracy of ±0.01% for most interfaces at 25 °C, and 24-bit resolution. Parameterization options are available for the analog input, which supports measurement functions U, I, R, DMS (strain gauge), and RTD. Optionally, measured data can be transmitted to higher-level automation devices with oversampling. The integrated distributed clocks ensure synchronized sampling across the EtherCAT system. Available measurements include voltage, current, resistance, electrical resistance, RTD, strain gauge/load cell, and potentiometer.
