Adhesive Has Very High Thermal Conductivity
Premier die attach epoxy EP3HTSDA-1 features much higher
conductivity than other silver conductive epoxies. This video shows
how it is dispensed and applied to a defined area without tailing.

Protective Suits Made
Safer with MoistureTrapping
Film
Researchers at the National
University of Singapore are using
a novel 'super-hygroscopic'
material to reduce heat stress in
personal protective suits.
The new training technique uses positive reinforcement to teach a robot
to stack blocks. (Image: Will Kirk/Johns Hopkins University)
To stack blocks, Spot the robot needed to learn how to focus
on constructive actions. As the robot explored the blocks, it
quickly learned that correct behaviors for stacking earned high
points but incorrect ones earned nothing. Spot earned the
most by placing the last block on top of a four-block stack.
The training tactic not only worked but it also took just days
to teach the robot what used to take weeks. The team was able
to reduce the practice time by first training a simulated robot,
which is a lot like a video game, then running tests with Spot.
The robot quickly learns the right behavior to get the best reward.
In fact, what used to take a month of practice for the robot
to achieve 100 percent accuracy was done in two days.
Positive reinforcement not only worked to help the robot
teach itself to stack blocks but also with the point system, the
robot quickly learned several other tasks - even how to play a
simulated navigation game. The ability to learn from mistakes
in all types of situations is critical for designing a robot that
could adapt to new environments.
The team imagines these findings could help train household
robots to do laundry and wash dishes - tasks that could
help seniors live independently. It could also help design improved
self-driving cars or perform product assembly.
