This paper proposes a new approach of implementing low-level OS components, especially device drivers. We introduce the notion of concurrent objects into device driver programming. A device driver for every hardware device is implemented as independent concurrent objects. A device driver object has a single thread of control, so that mutual exclusion operations such as spl and semaphores are no...

INTELLIGENT robots which manipulate objects using visual information have been studied and experimental models have already been developed in various laboratories. ~1-3) Generally the intelligent robot consists of the visual system, the handling system and the supervisory system that links these systems. The visual system and handling system are usually combined together as an open loop system....

The purpose of this review is to name and describe the important factors of musculoskeletal strain originating from pushing and pulling tasks such as cart handling that are commonly found in industrial contexts. A literature database search was performed using the research platform Web of Science. For a study to be included in this review differences in measured or calculated strain had to be i...

Energy consumption is an important design parameter for embedded and portable systems. Software-controlled (or dynamic) power management (DPM) has emerged as an attractive alternative to inflexible hardware solutions. However, DPM via I/O device scheduling for real-time systems has not been considered before. We present an online I/O device scheduler, which we call lowenergy device scheduler (L...

Microfluidic diagnostic devices often require handling particles or cells with different sizes. In this investigation, a tunable hydrophoretic device was developed which consists of a polydimethylsiloxane (PDMS) slab with hydrophoretic channel, a PDMS diaphragm with pressure channel, and a glass slide. The height of the hydrophoretic channel can be tuned simply and reliably by deforming the ela...

In ‘atomistic’ device simulation the resolving of discrete charges onto a fine-grained simulation mesh can lead to problems. The sharply resolved Coloumb potential can cause simulation artefacts to appear in classical simulation environments using Boltzmann or Fermi–Dirac statistics. Various methods have been proposed in an effort to reduce or eliminate such artefacts as the localisation of mob...

Recent technologies, like general purpose computing GPU, have a major limitation consisting in the difficulties that developers face when implementing parallel code using deviceoriented languages. This paper aims to assist developers by automatically producing snippets of code handling GPU-oriented tasks. Our proposed approach is based on Aspect-OrientedProgramming and generates modules in CUDA...

The ability to concentrate cells from dilute samples into smaller volumes is an essential process step for most biological assays. Volumetric concentration is typically achieved via centrifugation, but this technique is not well suited for handling small number of cells, especially outside of the laboratory setting. In this work, we describe a novel device that combines acoustofluidics with a r...

In this work, a method is presented for dispensing droplets. The method exploits the built-in capacitance of an electrowetting device to meter the droplet volume and control the dispensing process dynamically. A fully automated droplet dispensing device is developed and used to load liquid samples or couple continuous flow to electro-wetting droplet handling. The reproducibility of the dispensi...
