Philips Domestic Appliances and Personal Care (Philips DAP) is one of the product divisions of Royal Philips Electronics, alongside Consumer Electronics, Lighting and Medical Systems. In this article we will focus on sensors that are needed within the DAP division. Philips DAP has four Business Units, each with its own specific field of interest Shaving Grooming, Body Beauty Health, Food Beverage and Home Environment Care.

Until the past decade, the cytoplasm was widely considered to be structurally unorganized with the main division of labor at the organellar level. Certainly, relatively little was known about the nature of the cyto-skeleton (with the notable exception of the mitotic apparatus and striated muscle), and the dynamics of cytoplasmic behavior were conceptualized vaguely in terms of sol-gel transitions without a sound molecular foundation. Substantial improvements in electron, light, and fluorescence microscopy, as well as the isolation of discrete protein components of the cytoskeleton, have led the way to a much better appreciation of the structural organization of the cytoplasm. Indeed, the lacelike network of thin filaments, intermediate filaments, and microtubules in nonmuscle cells is as familiar today as the organelles identified... 

The enzyme as isolated is in a stable blue radical form (Fig. 23-50 also Fig. 15-13) which must undergo a one-electron light-induced reduction to the anion FADH- before becoming active. A nearby indole ring...

For many-electron light atoms, the Russell-Saunders coupling rules prevail One combines the orbital angular momenta lt of each electron, treated as a vector, to form the total orbital angular momentum quantum number (and vector) L = h one similarly couples the spin angular momentum quantum numbers s, into a total spin angular momentum quantum number S = s > then one adds L and S to get the total angular momentum vector... 

The area in which matrix isolation is perhaps of greatest value is the stabilization of transient species such as free radicals and high-temperature vapors. Until quite recently, infrared spectroscopy was utilized almost exclusively for the vibrational studies of matrix-isolated species. With the introduction of laser sources and the development of more sensitive, electronic, light detection systems, Raman matrix-isolation studies are now feasible and have recently been applied to a limited number of unstable inorganic fluoride species including the molecules OF (5) and C1F2 (6). Both of these species were formed for Raman study by a novel technique that utilizes the... 

Because a photon with energy less than 0 (v < v0) cannot remove an electron, light with a frequency less than the threshold frequency produces no electrons. On the other hand, for light where v > v0, the energy in excess of that required to remove the electron is given to the electron as kinetic energy (KE) ... 

As previously discussed, electron, light, and confocal microscopy techniques may be used to visualize the position of electron-dense precipitates, radioactive substances, and fluorescent probes, respectively, in the sample tissue. However, none of these techniques possess the capability both to visualize and to selectively measure the flux of a molecule across the skin. SECM, however, permits the measurement and subsequent imaging of the local flux of an electroactive species across biological membranes. Scott et al. [3] used SECM to investigate the effect of pretreatment of the penetration enhancer sodium dodecyl sulfate (SDS), on the ion transport rate and transport pathways of Fe(CN) across hairless mouse skin. Increasing the time of SDS exposure from 10 min to 30 min increased the overall (porous and nonporous) transport of Fe(CN) by 17-fold. More specifically, the SDS-induced increase in Fe(CN)g transport was found to be associated with nonporous (i.e., intercellular) transport routes, while transport via porous routes was significantly reduced. The fraction of Fe(CN)g transport through pores, as measured by... 

On the Osaka University thermionic cathode L-band linac, a time resolution of two picoseconds was achieved using magnetic pulse compression and time jitter compensation systems (Fig. 13). The time jitter between the Cerenkov light from the electron beam and the laser pulse was measured shot-by-shot with a femtosecond streak camera to accurately determine the relative time of each measurement in the kinetic trace. In this way, the time jitter that would otherwise degrade the time resolution was corrected, and the remaining factor dominating the rise time was the electron-light velocity difference over the 2-mm sample depth.

However, there are limitations to the technique when assessing phase purity and also in general. Since X-rays are scattered by electrons, light elements with few electrons scatter poorly in comparison with heavy elements. Therefore, if several phases are present and one contains a heavy element and the others do not, e.g. lead carbonate mixed with magnesium oxide and carbon, then the former will produce a much... 

Furnace camera technology, while meeting today s needs, continues to evolve and progress as it incorporates the latest advances. Until recently, the state of the art in these cameras was 480 lines of resolution. Recently, 540-line-resolution cameras became available, with better color rendition and more sophisticated electronics. Light volume control, allowing users to adjust the amount of light to see the different areas and depths within the furnace in a bright application, continues to be very critical and is very advanced.

The phenomenon of diffraction introduces a certain fuzziness or uncertainty into the trajectories followed by the diffracting particles. Figure 3.3 shows the situation at the moment of collision of a diffracting particle (electron, light atom or molecule) with a surface. The first uncertainty arises in the position of impact of the particle with the surface. Diffraction can occur only if the interaction with the surface extends over more than one lattice spacing, which means that the uncertainty in...
