Sponge Connectors

Fujipoly® America Corp., Carteret, NJ, offers Fujipoly® Self-Supporting Sponge Connectors for connecting LCD displays to circuit boards. Each connector is made from an electrically conductive Zebra® core that is supported by a low-compression-force silicone sponge on either one or two sides. The soft supports create a larger base width and eliminate the need to install a separate holder. The connector is available in a choice of widths to accommodate LCDs with a minimum glass lip overhang of 0.060"/1.5 mm.

Antenna Basics

The antenna is the most intrinsic component of all RF systems, yet the principles of antenna design and wave propagation are rarely discussed outside the entry level engineering classes. Rohde & Schwarz has developed an educational white paper on Antenna Basics to reteach the basic principles in a simplified manner.

The Economics of Accuracy in Low-cost, High-volume Sensing Applications

Various research firms forecast the market for portable medical devices to be somewhere around the $20 billion-range within the next several years. Part of the increased demand is due to an aging population with more chronic conditions. These smaller portable units requires devices with smaller footprints. By the same token, smaller devices need to provide adequate levels of care to ensure patient safety and comfort. Thus, functionality cannot be sacrificed for space.

Improve Encoder Performance With EtherNet/IP

As industrial automation networks go, EtherNet/IP has more than its share of advantages. It’s fast. It’s flexible. It’s easy to set up. It’s robust. Those advantages, however, come at a price. Users have to invest in infrastructure and devices certified to work with the EtherNet/IP standard.Today, EtherNet/IP is among the most popular industrial networks, and there’s no shortage of compliant devices. Consider motion control applications, for example. There are hundreds of EtherNet/IP actuators, drives, controllers and sensors on the market today.

Developing and Testing Electronic Control Units for Electric Drives

Air framers are looking to build more eco-friendly and economical aircraft, and they are turning to electric drives. One growing trend is to build more electrical aircraft by replacing pneumatic and hydraulic systems with electric actuators. Electric drives, therefore, will play an important role in the aircraft of the future. This paper examines the current state of technology for developing and testing electric drives.

Method of Forming Textured Silicon Substrate by Maskless Cryogenic Etching

NASA’s Jet Propulsion Laboratory has developed an advanced energy-storage device to accommodate portable devices, minimize emissions from automobiles, and enable more challenging space missions. The use of silicon for the anode of lithium ion (Li-ion) batteries is attractive because silicon has the highest theoretical charge capacity of any material when used as an anode in a Li-ion battery. Conventional silicon anodes undergo large-volume expansions and contractions with the absorption and desorption of Li-ions, however, and this results in pulverization of the anode after several charge and discharge cycles. JPL’s innovative Li-ion battery anodes are made of micro-textured silicon, which is able to accommodate the stress of expansion and contraction during the charging cycle. These robust silicon anodes make high-capacity, rapid-charge-rate Li-ion batteries practical.

An Apparatus and Method for Communication Over Power Lines

NASA’s Glenn Research Center is offering a sensor and actuator networking innovation applicable to smart vehicle or component control. This innovation requires no additional connectivity beyond the wiring providing power. This results in lower system weight, increased ease and flexibility for system modifications and retrofits, and improved reliability and robustness. The technology was specifically designed for harsh, high-heat environments, but has applications in multiple arenas. The device is compatible with most communication protocols.
