Monitoring physiological and behavioral signals to detect mood changes of bipolar patients
(2011)In this paper we present a personal, cost-effective, multi-parametric monitoring system based on textile platforms and portable sensing devices for the long term and short term acquisition of data from bipolar patients ... -
Driving an eXtra Small Atomic Resonator with low-power integrated RF frequency and laser locked loops
(2011-05)The first prototype of an eXtra Small Atomic Resonator (XSAR) was presented by CSEM in 2009. This paper describes the progress realized in 2010 towards the realization of a low-power miniature atomic clock. We present a ... -
Optical bistability in InGaN-based multisection laser diodes
(2011-05-09)Optical bistability is observed in cw-operating InGaN-based laser diodes including a saturable absorber (SA) section. The dependence of the light-current hysteresis on the SA section length and reverse bias (VSA)(VSA)<math ... -
Hybrid polymer microlens arrays with high numerical apertures fabricated using simple ink-jet printing technique
(2011-06-01)Microlens arrays fabricated by a direct ink-jet printing of UV-curable hybrid polymer are reported. A periodic pattern of polymer drops was ink-jet printed on the surface-treated glass substrate and cured in the UV-light. ... -
Consistency between backscatter lidar products and visibility range
(2011-06-18)We present a consistency of the following values: the aerosol backscatter coefficient (ABC) and top of Atmospheric Boundary Layer (ABL), derived from backscatter lidar measurements from one side, and the visually determined ... -
Self-referenceable frequency comb from a gigahertz diode-pumped solid-state laser
(2011-08-15)We present carrier envelope offset (CEO) frequency detection of a diode-pumped Yb:KGW (ytterbium-doped potassium gadolinium tungstate) laser with a repetition rate of 1 GHz. The SESAM-soliton-modelocked laser delivers 2.2-W ... -
Theory of the ultrafast mode-locked GaN lasers in a large-signal regime
(2011-08-29)Analytical theory of the high-power passively mode-locked laser with a slow absorber is developed. In distinguishing from previous treatment, our model is valid at pulse energies well exceeding the saturation energy of ...
