Chronic wounds represent a significant burden to patients, health care professionals, and health care systems, affecting over 40 million patients and creating costs of approximately 40 billion annually. Goal of the project is the fabrication of a medical device for professional wound care. The device will use recently proven therapeutic effects of visible light to enhance the self-healing process and monitor the status and history of the wound during therapy. Light exposure in the red part of the spectrum (620-750nm) induces growth of keratinocytes and fibroblasts in deeper layers of the skin. The blue part of the spectrum (450495nm) is known to have antibacterial effects predominantly at the surface layers of the skin. In order to be compliant with hygiene requirements the system will consist of two parts: 1. a disposable wound dressing with embedded optical waveguides and integrated sensors for the delivery of light and monitoring (temperature and blood oxygen) of the wound. 2. a soft and compliant electronic module for multiple use containing LEDs, a photodiode, a controller, analog data acquisition, a rechargeable battery, and a data transmission unit. Both parts of the device will be interconnected by a mechanically robust plug, enabling a low loss coupling of light into the waveguide structures and electrical interconnection to the sensors. The status of the wound will be monitored with temporal and low level spatial resolution. The electronic module will be optimized for functionality and user comfort, combining leading edge heterogeneous integration technologies (PCB embedding) and stretchable electronics approaches. The detailed effects of light-exposure schemes will be explored and backed by in-vitro and in-vivo animal studies. Results will be used to develop smart algorithms and implement it into respective programs and feedback loops of the device.

The Tamessa project represents a step change in harsh environment electronic assembly. Tamessa will develop a integrated system will eliminate the need to use expensive & heavy ceramic technologies in applications up to 225Deg C and allow the integration of bespoke through hole components. Typical applications benefiting from this system are aerospace, automotive, offshore & power management or other areas were electronics are subjected to high temperature, salt and hydrocarbons. OEMs will benefit from 30% reduction in board cost, 50% reduction in board weight and 95% reduction in tooling NRE cost. Energy cost associated with manufacture are signifcantly reduced.


A digital phase locked loop has a phase acquisition module that outputs a first phase value representative of the phase of a reference signal expressed with respect to an internal phase reference. A phase offset write module convert a phases offset commanded from an external source into a phase offset correction value expressed with respect to the internal phase reference. A phase offset controller sums the phase offset correction values to produce a second phase value, which is added to the first phase value to produce a third phase value expressed with respect to the internal phase reference. A digital controlled oscillator (DCO) outputs a fourth phase value expressed with respect to the internal phase reference. A phase detector outputs a fifth phase value representing the difference between the third and fourth phase values. A loop filter derives a frequency offset for the DCO based on the fifth phase value. An output module generates one or more output clocks from the fourth phase value.

A clock generator with glitchless phase adjustment having a phase locked loop with a controlled oscillator providing an output representing a phase value. One or more output modules generate one or more output clocks from the output. One or more adjustment modules add a requested phase adjustment to an output clock. The phase adjustment modules are configured to break the requested phase adjustment into smaller increments and apply the increments to an output clock generated in said at the output modules one cycle at a time.
