Sustainable printing for the Chinese consumer market

Worldwide, consumers demand companies to take more responsibility for what environmental problems their products might cause. Companies are following this demand from consumers by producing more sustainable products. HP forms no exception and has implemented so called “Eco solutions” to reduce the environmental impact of their consumer inkjet...

Feedback in voluntary closing arm prostheses: Investigation of optimal force feedback in shoulder controlled arm prosthesis operation

High rejection rates indicate that prosthetic users are not satisfied with the performance of their arm prostheses. In theory, one of the advantages of shoulder controlled prosthesis, compared to myo-electric prostheses, is that the user gets direct proprioceptive feedback about opening width and pinch force of his prosthetic hand. However,...

Improving the Quality of Haptic Feedback Yields Only Marginal Improvements in Teleoperated Task Performance

In teleoperations, haptic feedback allows the human operator to touch the remote environment. Yet it is only partially understood to what extent the quality of haptic feedback contributes to human-in-the-loop task performance. This paper presents a human factors experiment in which telemanipulated task performance is assessed for three stages of...

Design of LNTA for Multi-Band WCDMA

Currently, a low cost, single-chip multi-band WCDMA/GSM transceiver is needed for the 3G segment of the cellular communication that provides backward compatibility with the 2G GSM network. In this thesis, a novel, multi-band, low noise transconductance amplifier (LNTA) is presented. The LNTA has three stages, which are the transconductance,...

Digital Cartesian feedback linearization of power amplifiers

The efficient use of the power budget in mobiles and small satellite applications is of primary importance because of the reduced size of the power sources. The limited power supply has to be spent wisely. In a transmitter, the power amplifier is the main consumer of that budget, which is why it has to be as efficient as possible. Unfortunately,...

Jacket for people with balancing problems

This report concerns the development of a jacket for people with balance problems. Patients with failing balance organs can have serious difficulty to maintain their balance. The balance jacket contains a sensor and a belt of actuators. The sensor determines the orientation of the patient and provised feedback to the jacket. The jacket contains...

A new perspective on continental moisture recycling

The importance of moisture feedback between continental precipitation and evaporation, referred to as moisture recycling, is still under debate. Most of the research in the past focused on the contribution of recycling to precipitation within a certain region only. This paper clearly distinguishes between different definitions of moisture...
