A near-to-eye display system for forming an image as an illuminated region on a retina of at least one eye of a user is disclosed. The system includes a source of modulated light, a proximal optic positionable adjacent an eye of the user to receive the modulated light. The proximal optic has a plurality of groups of optically redirecting regions. The optically redirecting regions are configured to direct a plurality of beams of the modulated light into a pupil of the eye to form a contiguous illuminated portion of the retina of the eye. A first group of the optically redirecting regions is configured to receive modulated light from the source and redirect beams of the modulated light into the pupil of the eye for illumination of a first portion of the retina. A second group of the optically redirecting regions is configured to receive modulated light from the source and redirect beams of the modulated light into the pupil of the eye for illumination of a second portion of the retina.

The present invention describes the use of two semiconductor layers, a thin film (TF) layer and a bulk Si wafer layer, to make high density and high speed merged logic and memory IC chips. The memory cells use three-dimensional (3D) SRAM structures. Two kinds of 3D logic cells are disclosed. 3D form of the differential cascode voltage switch (DCVS) architecture, and a 3D form of the DCVS with pass gate (DCVSPG) logic architecture. A high density "system on chip" architecture is described. The high density is achieved by locating large PMOS transistors in the TF Si layer, and the fast NMOS transistors in a bulk Si wafer layer. A single process sequence to simultaneously make the logic and memory circuits on the IC chip is also described.

A high-intensity light source configuration has a long lifetime and can be modulated at a high rate. The configuration includes a movable member mounted to an actuator; a light-emitting phosphor region associated with the movable member; an input light source that illuminates the light-emitting phosphor region at a spot that is fixed relative to an emitted light output region; and a light source controller controlling the movable member actuator and the input light source. The input light source (e.g., laser) provides high-intensity input light to the illuminated spot, causing the light-emitting phosphor region to emit high-intensity output light. The light-emitting phosphor region is moved relative to the illuminated spot so as to reduce optical quenching and photobleaching, to thereby extend the life of the light source configuration. The phosphor region may emit broadband light and/or may include respective sub-regions having phosphors that emit respective peak wavelengths.

A cartridge having at least one layer containing sodium zirconium phosphate and at least one layer containing a combination of acid zirconium phosphate and alkaline hydrous zirconium oxide is described. Methods of using the cartridge for water purification are also described.

The present invention provides improved optical switches in which only a spatial beam shifting of a small free space offset is required to direct optical pathways between plural fiber ports. This is achieved by spacing two fibers closely and collimating their beams with one imaging lens for compactness. Advantageously, the inventive switches incorporate beam correcting devices to render the beam propagations parallel, allowing light beams to be efficiently coupled into two fibers that sharing a single lens with substantially improved stability.

A horizontal articulated robot has a plurality of horizontal arms coupled by joint shafts, and a working shaft disposed at the extreme end of an extreme end arm among the horizontal arms has mounting portions of an end effector formed to both the upper and lower ends thereof. With this arrangement, there can be provided a horizontal articulated robot that can cope with various work transport forms and various types of works by one type of a robot by selectively using the upper and lower sides of a working shaft.

The linear accelerator comprises an acceleration cavity shell, a core pipe and at least three tandem four-pole magnets, wherein the acceleration cavity shell is located in an acceleration cavity and is connected with the inner wall of the acceleration cavity; the core pipe is located in the acceleration cavity shell and allows particle beams to pass,and the four-pole magnets are located in a magnet cavity shell, are used for focusing the particle beams and comprise central through holes, and the core pipes penetrate through the central through holes. A synchronous accelerator is characterized in that the linear accelerator is taken as an injector of the synchronous accelerator.

A microwave transmitting device for a level measuring device (1) having an electronic device, a microwave emitter and a waveguide (3). The inside of the waveguide is filled with a casting compound. A microwave transmitting device that is particularly compact and cost-effective is implemented by the microwave emitter and the electronic device being enclosed by a casting formed of a casting/potting compound.

The present invention relates to a cell culture device (1) comprising a disposable culture vessel comprising at least one external wall made of a material having a Young modulus E of less than 50 GPa, in which there is situated at least one cell culture zone and at least one cell-free medium transfer zone, allowing a flow of a culture medium between the cell culture zone and the transfer zone, and at least one sensor element of a cell-density sensor wherein said sensor element is situated in the cell culture zone of said vessel. The sensor element is an electrode arrangement of at least two and preferably at least four measuring electrodes arranged on the inner side of an external wall of the disposable culture vessel and directed towards the cell culture zone. The present invention further relates to a method of culturing cells.

A packaged unit screw compressor includes a low-pressure stage compressor and a high-pressure stage compressor. The raw power from the electric motor is transmitted to the two compressors through the speed increaser. The exhaust gas compressed and heated by the low-pressure stage compressor is cooled by the intercooler. The exhaust gas, which is compressed and heated by the high-pressure stage compressor to increase its temperature, is cooled by the aftercooler. The casing of the intercooler, the casing of the aftercooler and the casing of the speed increaser are integrated, thereby reducing the number of components. The cooler section formed by the intercooler and the aftercooler is separated from the speed-up case, thereby preventing heat generated by the compressed air from being transferred to the speed-up case.

The invention relates to a silencer for exhaust systems of motor vehicles with an internal combustion engine. The silencer includes an exhaust gas flow pipe for guiding exhaust gas with an exhaust gas inlet opening, an exhaust gas outlet opening having a flow connection to the exhaust gas inlet opening, and a longitudinal center axis. It furthermore has at least one actuable adjustment body for influencing the flow of the exhaust gas in the exhaust gas flow gas pipe, the at least one adjustment body being arranged downstream of the exhaust gas inlet opening. Moreover, the silencer includes at least one bypass channel, which has a flow connection to the exhaust gas flow pipe, runs past the at least one adjustment body and has an exhaust gas outlet opening.
