Motion Control with Vision

This paper describes the work that is done by a group of I3 students at Philips CFT in Eindhoven, Netherlands. I3 is an initiative of Fontys University of Professional Education also located in Eindhoven. The work focuses on the use of computer vision in motion control. Experiments are done with several techniques for object recognition and tracking, and with the guidance of a robot movement by means of computer vision. These experiments involve detection of coloured objects, object detection based on specific features, template matching with automatically generated templates, and interaction of a robot with a physical object that is viewed by a camera mounted on the robot.

A Testbench Driven FR2 EMF Sensor Development and Validation

The 5th generation of mobile communications is designed to employ both FR1 and FR2 bands throughout the world. The higher frequency bands (i.e., FR2 n257 26.50 - 29.50 GHz) are posing several challenges to operators and national telecom agencies for performing electromagnetic fields (EMF) measurements. In this work we present the design and preliminary evaluation of an FR2 sensor node to measure EMF radiations in urban environments. The design is carried out in an RF circuit design software, i.e., Keysight ADS, where the various nonidealities (i.e., nonlinearities, noise behavior and electromagnetic response) of the various sub blocks of the systems are accounted for. The sensor concept is then implemented in a prototype board technology (i.e., X-microwave) and its response is experimentally verified in the FR2 band.

Three-dimensionality of contact forces during clinical manual examination and treatment : a new measuring system

Description of a new hand/palm-held computerized 3D force measuring system. The system is built for interface (direct) measurement of 3D manual contact force with real-time data presentation. Static calibration was performed of the 3D force sensor with variable preloads to study their effect as well of the prototype system adapted for clinical manual examination and treatment. The new system enables, for the first time, recording and presenting of 3D manual contact forces at the patient-practitioner interface. 3D direct manual contact force measures have the potential to give a more complete and differentiated characterization of patient and practitioner forces than 1D forces. Clinical validity of the prototype system will have to be investigated, and for studying specific clinical manual handling techniques, obvious limitations require further development.

Speech privacy in multiple-bed patient rooms

While research has shown the multiple benefits of single-bed patient rooms in hospitals, amongst which the experience of privacy and dignity, the majority of patient rooms in existing hospitals are shared. Transforming them into single-patient rooms can be time-consuming, costly or even impossible, which motivates this study looking into privacy in multiple-patient rooms. To share a hospital room, means to share sensitive information with total strangers. This may cause uncomfortable situations for both patients. Furthermore, the awareness of other ears in the room can withhold some patients from sharing important information during daily ward rounds The aim of this study was to investigate the acoustic effect and the acceptance of an adjustable sound masking system in a 4-bed patient room. The objective of the system is that when a doctor shares personal information with one patient, the other patients in the room are not able to understand the conversation.

Essential requirements for securing consumer IoT devices

Embedded connected computers are installed in homes in increasing numbers in the form of consumer IoT devices. These devices are often insufficiently protected against cyberattacks. In this research report, we propose several security requirements for consumer IoT devices. These requirements are suitable for enforcement through legislation and will significantly improve consumer IoT cybersecurity when implemented.This research report, commissioned by the Dutch Radiocommunications Agency, describes a threat model and significant security problems, derived from literature research. These assisted in evaluating more than 400 security measures, after which the top measures were summarised into eight essential security requirements. These requirements are easy to implement, easy to test, unambiguous, and greatly improve the cybersecurity of the products. We recommend standardisation agencies to make these requirements mandatory for all consumer IoT devices.
