A nano particle reinforced polymer element of a stator and rotor assembly for a power section of a positive displacement fluid motor or a progressive cavity pump. Nano-sized particles are blended with an uncured polymer to improve the physical and chemical properties of the polymer. The use of nano-sized particles reduces the quantity of reinforcement material required to manufacture the polymer for the stator and rotor assembly and lowers the viscosity of the uncured polymer to improve manufacturing characteristics. The use of chemically functionalized nano particles improves the chemical and physical characteristics of the polymer.

A power converter circuitry for converting a DC voltage generated by a generator with varying output power in the mean voltage range into an alternating voltage for feeding into a grid, with several series-connected power converters, which are connected in parallel with said generator, as well as with a controllable bridging switch for each power converter, said bridging switch lying in a direct voltage intermediate circuit and bridging the respective power converter in the closed condition, is intended to be used for a photovoltaic generator. This is achieved in that a resistance chopper is connected between each power converter and the generator, no input diode being provided in the current path from the generator to the power converter, and that each bridging switch is connected in parallel with the resistance chopper in the direct voltage intermediate circuit.

A tubular guidewire assembly having a distal occlusive device and an extended crimpable section proximate a proximal end that is adapted to connect to a gas inflation/evacuation system. The extended crimpable section can be selectively sealed at one of a plurality of separate locations to form an airtight seal of the tubular guidewire assembly. Each time a deflation of the occlusive device is desired in order to reestablish blood flow to a vessel downstream of the occlusive device, the extended crimpable section preferably is cut distal to the location of the last seal to quickly deflate the occlusive device.

A method for performing a common cancel (CC) function on a dynamic random access memory (DRAM) semiconductor device to improve reliability and speed of a memory system. The CC function rakes advantage of the intrinsic delays associated wit memory read operations at high clock frequencies, and the increased write latency commensurate with increased read latencies where non-zero larencies for read and write operations are the norm by permitting address and command ECC structures to operate in parallel with the address and command re-drive circuitt The CC function is extendable to future DDR2 and DDR3 operating requirements in which latency of higher frequency modes will increase due to the shift from 2 bit pre-fetch to 4 and 8 bit pre-fetch architecture.

A radio base station has a baseband unit (BB) and multiple RF heads (RH1, RH2), which are interconnected by means of a bi-directional two-fiber optical ring (R). Each RF head (RH1, RH2) has a delay counter (31) for determining a propagation delay (tL) on the ring (R) and a variable delay circuit (16, 26) for compensating a difference between the propagation delay on the ring and a predefined target delay (tRR). The delay counter counts (31) the delay between a test signal sent on the first fiber (F1) of the ring to the baseband unit and a received test signal looped back by the baseband unit on the second fiber (F2) of the ring.

A strengthened glass container or vessel such as, but not limited to, vials for holding pharmaceutical products or vaccines in a hermetic and/or sterile state. The strengthened glass container undergoes a strengthening process that produces compression at the surface and tension within the container wall. The strengthening process is designed such that the tension within the wall is great enough to ensure catastrophic failure of the container, thus rendering the product unusable, should sterility be compromised by a through-wall crack. The tension is greater than a threshold central tension, above which catastrophic failure of the container is guaranteed, thus eliminating any potential for violation of pharmaceutical integrity.

A facsimile machine provides file specifying information of a transmission file to an agent software. The agent software runs an appropriate application program in accordance with the file specifying information. By using this function, a prescribed file on a data conversion device is converted directly into an image content via a network from the facsimile machine. Accordingly, a facsimile transmission of the image content to a prescribed destination can be carried out just by an operation from the facsimile machine. As a result, an efficiency of a facsimile transmission process is improved.
