Display apparatus, display system and cable

Abstract: In order to automatically distinguish a type of cable connected to a display apparatus, and transmit appropriate specification information to a host, when a host 10 and a display apparatus 100 are connected via a DVI-D to DVI-D cable 14 for digital signal, a DDC 5V from the host is applied to an emitter of a detection transistor 19 , and a lower voltage due to a resistor 17 is applied to its base so that the detection transistor turns on. A collector voltage thus becomes an H level so that a multiplexer 21 is switched to the side of a non-volatile memory 23 in which a digital EDID is stored. When they are connected via a D-Sub to DVI-I conversion cable 15 for analog signal, a DDC 5V terminal and an HPD terminal of the cable are short circuited, so the detection transistor turns off, the collector voltage becomes an L, and the multiplexer is switched to the non-volatile memory side in which an analog EDID is stored.

Cellular telephone with ear proximity display and lighting control

Abstract: A cell phone includes illuminated components and a proximity sensor. The proximity sensor detects when the cell phone is coupled to the ear of a user. Therefore, the proximity detector is placed, in part, near the loudspeaker of the cell phone. The proximity sensor controls the illumination of the illuminated components according to the coupling. The illumination is off when coupled, an on when not coupled. The amount of illumination can depend to the intensity of ambient light as measured by a photodiode.

Effect Plasma Transport on Etched Profiles with Surface Topography in Diverging Field Electron Cyclotron Resonance Plasma.

Abstract: Recent studies of electron cyclotron resonance (ECR) plasma etching for fabricating fine patterns of less than a half-micron indicate a serious problem in the etched profiles caused by a charge build-up of the patterns. The relationships between the local pattern distortion and the plasma properties measured by the electrostatic probe are investigated. Lowering the electron temperature perpendicular to the surface normal is one of the most effective techniques for eliminating the local side etch. It is enhanced by setting the wafer at the lower magnetic field. As the large space charge bends the ion trajectories, the higher ion current density also enhances the local side etch. The distribution of plasma potential which accelerates the ions can reduce the local side etch in spite of the higher current density.

Correlations of pedometer readings with energy expenditure in workers during free-living daily activities

Abstract: In a total of 23 subjects consisting of 10 clerical and 13 assembly workers in a factory, the pedometer readings during a day of free-living activity were analyzed for the relation with energy expenditure as determined by the simultaneously recorded 24-hour heart rate. The 24-hour energy expenditures in the clerical and assembly workers were 9515 kJ (2274 kcal) and 9698 kJ (2318 kcal) respectively. The whole day readings of the pedometer for all the subjects moderately correlated (r=0.438,p 0.05). The correlation analysis of the pedometer readings with the NEC in three activity phases in a day (work, commuting and staying at home), showed that the extent of the relationship differed by job types and activity phases. The best correlation was obtained during commuting in both of the job types (clerical workers:r=0.843,p<0.01; assembly workers:r=0.743,p<0.01). During work, a quite strong correlation (r=0.889,p<0.01) was obtained with the clerical workers but not with the assembly workers. No significant correlations were found in the data while the subjects were at home. The capacity of the pedometer to detect the impacts of body movements, and the characteristics of activity, are responsible for the differences in correlation. The limitations of the pedometer suggested in the present study must be taken into account if the device is to be used for measuring physical activity. A particular advantage of the device appears in its use for a sedentary population without regular srenuous exercise or static contractions.

Graphene on metal-insulator-metal-based plasmonic metamaterials at infrared wavelengths.

Abstract: Metal-insulator-metal-based plasmonic metamaterial absorbers (MIM-PMAs) generate strong localized surface plasmon resonance (LSPR) on their surfaces. Therefore, MIM-PMAs are expected to enhance the absorption of graphene coated on their surfaces. Graphene-coated MIM-PMAs (GMIM-PMAs) were developed and their optical properties were investigated both experimentally and numerically at infrared wavelengths. Significant modification of the absorption of GMIM-PMAs was achieved only in the main LSPR wavelength region, where the insulator is lossless. The enhancement of the absorption of graphene could be maximized by the optimization of the insulator thickness of the MIM-PMAs. The results obtained here are expected to contribute to the development of high-responsivity graphene-based photodetectors and optoelectronic devices.
