TL;DR: The feasibility of the plastic waveguide interconnect interconnect is shown as a promising alternative to electrical, optical, and wireless interconnects.
Abstract: A new interconnect solution with plastic waveguide is demonstrated. The system consists of a pair of transceivers and a plastic waveguide. Millimeter wave signal is transmitted in a low-cost long piece of solid plastic dielectric acting as a waveguide. The plastic waveguide medium offers a large bandwidth for data communication using mm-wave carrier frequencies. Plastic waveguide interconnects do not require costly electrical-to-optical and optical-to-electrical conversion devices or precise alignment and offer longer transmission distances than wireless solutions due to better field confinement and lower path loss. Multiple plastic waveguides can be used in parallel and the modulated data at different frequencies can be multiplexed to increase the data rate. The demonstrated transceiver chips operate at carrier frequencies of 57 GHz and 80 GHz, and are fabricated in 40 nm low-power logic CMOS. The total area and power consumption of two transceivers are 0.41 mm2 and 140 mW, respectively. The fabricated demonstrator with Yagi-couplers achieves full-duplex transmission of 12.5 Gb/s ASK modulated signal in each direction over the 120 mm polystyrene waveguide with no equalization. The observed bit error rates for both channels are less than 10-12 for a PRBS length of 27-1 at the total data rate of 25 Gb/s. This paper shows the feasibility of the plastic waveguide interconnect as a promising alternative to electrical, optical, and wireless interconnects.

TL;DR: In this article, an imaging apparatus includes an imaging device that images an object image through an optical system, an image signal processing section having a function of combining a plurality of imaged images into a combined image piece, the images being obtained while the imaging apparatus is swept, and a controller that processes information of the position sensor, wherein the controller sends a notification of an appropriate value of a sweeping angular velocity based on the detection information of position sensor and outputs a warning signal when the sweeping angular velocities exceeds an appropriate range.

TL;DR: In this paper, the exciton relaxation processes were studied by use of time-resolved photoluminescence (PL) spectroscopy, indicating the dynamical features of exciton localization.
Abstract: Exciton localization in ${\mathrm{In}}_{x}{\mathrm{Ga}}_{1\ensuremath{-}x}\mathrm{N}$ was studied. At 2 K, the time-integrated photoluminescence (PL) spectrum showed a Stokes shift from the absorption shoulder and broadening at the lower photon energy side. Site-selectively excited PL measurements determined the mobility edge. The exciton relaxation processes were studied by use of time-resolved PL spectroscopy. The PL decay time increased with the decrease of the detection-photon energy, indicating the dynamical features of exciton localization. In addition, we observed localized exciton luminescence turned into stimulated emission just below the mobility edge.

TL;DR: In this article, an eyesight auxiliary device has been described, having within a main body of the device, a spot light source, transparent liquid cyrstal panels illuminated by the spot light, and convex lenses substantially integrally arranged with the liquid crystal panels.
Abstract: An eyesight auxiliary device having within a main body of the device is described, a spot light source, transparent liquid cyrstal panels illuminated by the spot light source and convex lenses substantially integrally arranged with the liquid crystal panels. The main body of the device is fitted to a user's head, the image of the liquid crystal panels is directly projected onto the retina of the user's eyeballs through the spot light source. Further, a small-sized camera for capturing the image of the liquid crystal panels is arranged at a position corresponding to the height positions of the eyeballs.

TL;DR: In this paper, a specific contact resistance as low as 5.0*10/sup -2/ Omega cm/sup 2/ has been achieved for N-doped ZnSe with a hole concentration of 7.0 * 10/sup 16/ cm/SUP -3/.
Abstract: Employing p/sup +/-ZnTe/ZnSe quantum wells whose sub-bands are aligned in energy so that resonant tunnelling of holes can occur through the multiquantum well region, Au/Pt/Pd nonalloyed ohmic contacts to p-type ZnSe have been realised. A specific contact resistance as low as 5.0*10/sup -2/ Omega cm/sup 2/ has been achieved for N-doped ZnSe with a hole concentration of 7.0*10/sup 16/ cm/sup -3/. >
