PROBLEM TO BE SOLVED: To provide a microchip made of a resin with a microchannel with a channel sealed by an upper substrate which is transparent and absorbs little in ultraviolet region, is minute and has satisfactory surface smoothness, and is high in dimension accuracy. SOLUTION: The microchip for optically measuring a liquid sample has at least both a lower substrate with the microchannel through which the liquid sample flows and the upper substrate made of a flat film. At least the lower substrate is made of a transparent hydrocarbon-based polymer expressed by Fig. (1). At least the surface of the lower substrate on the side with the channel is treated with oxygen plasma, and then the lower substrate and the upper substrate are subjected to thermocompression bonding at temperatures lower than the glass-transition temperature (Tg) of the transparent hydrocarbon-based polymer to obtain the microchip.

Abstract:
PROBLEM TO BE SOLVED: To provide a method for producing a silicone elastomer stamp with a hydrophilic surface. SOLUTION: The method for fabricating silicone elastomer stamps with hydrophilic surfaces is provided. The concept of polymer grafting is used to produce the stamps. The stamps thus produced have the great advantage that grafting of a thin hydrophilic polymer on a hydrophobic PDMS surface can render PDMS stamps permanently hydrophilic. With such stamps, it becomes possible to print aqueous or highly polar inks reproducibly over days and weeks.

The volume hologram comprises a plurality of diffractive patterns disposed in sequence across the volume hologram, each of the plurality of diffractive patterns being configured to diffuse the light rays from the projection system in a determined direction corresponding to the specific diffractive pattern and oriented towards a position of an intended eye of a user wearing the display panel assembly.
Abstract:
A multi-core architecture with ultra-low power consumption is needed for a wide variety of applications, especially in the bio-medical domain. In this patent, an ultra-low power multi-core architecture is presented: it is composed of one or more cores, several (one or more] shared multi-banked instruction and data memories, and flexible crossbar interconnects. The interconnect includes a selective broadcasting mechanism, enabling coordinated multiple accesses to the shared memories, thus energy savings in the memory hierarchy and in the interconnects. The memory hierarchy enables power gating of the unused banks to lower leakage power. The core instruction set of the novel architecture has been customized to exploit the specific features of bio-signal events, as well as the highly parallel computation opportunities of bio-signal processing characteristics. In addition to near threshold computing, the proposed architecture also exploits other advanced low-power features, which lead to further energy savings. The architecture has a synchronization method and unit that allows power- efficient handling of data dependencies when code is parallelized across the multiple processing cores.

The invention concerns a method for producing ultrashort and ultrahigh peak power laser pulses and a system for putting into practice this method. The production of ultrashort and ultrahigh peak power laser pulses is implemented by amplifying and compressing relatively long and low energy laser pulses to such ultra short and ultrahigh peak power pulses, and the use of the plasma compression technique for producing ultrashort and ultrahigh peak power pulses having a duration in the range of 20 femtoseconds (fs) or less and an energy of at least 10 Kilojoule (kJ), wherein a pump pulse (PP) in the order of picoseconds (ps) and a seed pulse (SS) are applied to the plasma cell (PLC), which are synchronized with one another and adapted to the plasma cell.
