We describe a stochastic accumulator model demonstrating that visual search performance can be understood as a gated feedforward cascade from a salience map to multiple competing accumulators. The model quantitatively accounts for behavior and predicts neural dynamics of macaque monkeys performing visual search for a target stimulus among different numbers of distractors. The salience accumulat...

It has recently been shown that accumulators can be used elfciently for test pattem generation as well as for test response compaction. In this paper we present a BIST scheme for accumulators where the accumulator is simultaneously used as a test pattern generator and a response compactor during its own testing. We also show that the proposed BlST scheme is especially suitable for accumulator, ...

Energy storage devices for fluid power applications that are significantly more compact than existing ones will enable energy regeneration for many applications, including fluid power hybrid vehicles and construction equipment. The current approach to hydraulic energy storage makes use of a compressed gas enclosed in a closed chamber. As the system must contain the expanded gas and the hydrauli...
