A wireless method for monitoring medication compliance
… and a transmissive "electric eye" photosensor. Each mode exhibited blind spots or other failures to detect pill presence, but by combining modes with complementary characteristics, the accuracy of pill detection is greatly increased. Two methods of caregiver notification are …

H-NS Counter-silencing as a Primary Regulatory Mechanism of Curli Gene Expression in Salmonella Typhimurium
… allosteric regulator of MlrA and may serve as a photosensor to trigger biofilm formation in response to harmful UV irradiation. Characterization of counter-silencers in Salmonella can help us understand mechanisms of gene regulation that can be extrapolated to other organisms and provide new …

Développement d'un dispositif intégré de photodétection de grande sensibilité avec discrimination spectrale pour les laboratoires sur puce
This thesis aims to develop an integrated photosensor device for biomedical applications requiring high detection sensitivity and spectral discrimination (selectivity). For example, this system can be applied to mesure simultaneous emissions of several fluorescent labels in lab-on-a-chip …

Towards unveiling the Photoactive Yellow Proteins: characterization of a halophilic member and a proteomic approach to study light responses
… and which induces a unique dimerization of the photosensor with no precedents described before with any of the other published PYPs. Truncation of the N-terminal extension does not seem to influence the photochemical properties, and no structural motif or functional relevance towards signaling …

SYNTHESIS AND CHARACTERIZATION OF ZINC OXIDE BASED NANOSTRUCTURES AND COMPOSITES FOR ENERGY RELATED APPLICATIONS
… under ultra violet (UV) illumination. UV photosensor devices fabricated using these NW assemblies demonstrated a high photodetection abilities at room temperature under moderate UV illumination power of ~ 250 µW/cm2. These findings indicate the possibility of using ZnO NWs, grown using the …

Spectroscopic investigation of phytochromes and NIR fluorescent variants
… the lifetime of the Pfr state. Furthermore, the photosensor constructs with and without the PHY domain (PAS-GAF-PHY [PGP], PAS-GAF [PG]) were analyzed in solution and in the crystalline state. While the respective Pr states have unaltered chromophore structures, PCB adopts a configuration similar …

Arc-discharge In Solution: A Novel Synthesis Method For Carbon Nanotubes And In Situ Decoration Of Carbon Nanotubes With Nanoparticles
… between the two electrodes is maintained using a photosensor which allows a continuous synthesis of the carbon nanostructures. The system operates in a feedback loop consisting of an electrode-gap detector and an analogue electronic unit, as controller. This computerized feed system was also used …

Lighting Control Systems for Energy Saving and User Acceptance: State-of-the-art and future directions
Lighting accounts for one-fifth of global electricity use. In Sweden, energy demand for lighting corresponds to 20% of the total electricity use in office buildings. Lighting retrofit measures are considered to be among the most cost-efficient way to reduce energy use in buildings. In particular, …
