Cross roller ring can swing the loads
Because it has orthogonally arranged cylindrical rollers, the cross roller ring from THK is a roller bearing with high rotation accuracy capable of bearing loads in every direction. Cylindrical rollers are arranged with each roller perpendicular to the adjacent roller, in a 90-deg V groove, separated from each other by a spacer retainer. This design allows just one bearing to receive loads in all directions. This component is optimal for applications such as joints and swiveling units of industrial robots, swiveling tables of machining centers, precision rotary tables, and medical equipment. Rotation configurations include inner/outer ring, inner ring only, and outer ring only. A new micro cross roller ring is perfect to handle smaller applications.

7 reasons your life depends on an accurate IMU in a self-driving car
An inertial measurement unit (IMU) is a device that directly measures the three linear acceleration components and the three rotational rate components (6-DOF) of a vehicle. An IMU is unique among the sensors typically found in an autonomous vehicle because it requires no connection or knowledge of the external world. By Mike Horton, CTO, Aceinna

Metal tape measure tech grows up

When first-timers see the Zippermast rise into the air from an unmanned vehicle, they are amazed by how high it can be extended. Inspired by the lowly metal tape measure design, the compact and super-sturdy Zippermast consists of three interlocked steel tapes that also function like a locking zipper, lifting cameras and sensor equipment up to 40 ft in the air. A small DC motor from FAULHABER provides the unique design with reliable retraction and extension, all incorporated into an amazingly small base housing.

Videos+: Technologies and inspiration in action
Intro to using mouse gestures in SOLIDWORKS
Chris Joren, application engineer at TriMech Solutions in Knoxville, runs through the basics of using pre-programmed mouse gestures in SOLIDWORKS to save you time in design work. Mouse gestures are activated by simply right clicking and dragging your mouse in a certain direction. This direction corresponds to a SOLIDWORKS command that is set by you in the customization window. Very useful tips.

Solving analog-to-digital conversion challenges
Analog-to-digital converters (ADCs) are critical components in high-speed, high-resolution applications where an analog or RF signal has to be processed, stored, or transported in digital form. ADC performance requirements vary by application and include resolution, dynamic range, linearity, power consumption, speed, bandwidth, SNDR (Signal-to-Noise and Distortion Ratio), and ENOB (Effective Number of Bits). Watch this short overview video from Mentor to learn more about the key technology challenges associated with ADCs and how the Analog FastSPICE Platform can help address them.
