Abstract: Since CO2 is identified as a main greenhouse gas, its capture and storage is essential to control of global warming.  Flexible operation of CO2 capture and compression equipment will increase the competitiveness of power plants (1) designed for CO2 capture and compression and will allow earlier introduction of this kind of plants. The main objective of the present invention is to improve the plant operating characteristics by taking advantage of the additional flexibility, which can be realized by controlling the power consumption of the CO2 capture and compression system. One particular aim is to minimize the impact of CO2 capture and compression on the capacity of a power plant (1), i.e. to maximize the electric power the plant can deliver to the power grid.  Further, the impact of CO2 capture and compression on the average plant efficiency shall be reduced. Both are achieved by an operating method, in which the power consumption of the CO2 capture system is used to control the net output (D) of the plant.  Besides the method a power plant (1) designed to operate according to this method is subject of the present invention.

IPC: E21B47/12

Abstract: A side-hole optical cane for measuring pressure and/or temperature is disclosed. The side-hole cane has a light guiding core containing a sensor and a cladding containing symmetrical side-holes extending substantially parallel to the core. The side-holes cause an asymmetric stress across the core of the sensor creating a birefringent sensor. The sensor, preferably a Bragg grating, reflects a first and second wavelength each associated with orthogonal polarization vectors, wherein the degree of separation between the two is proportional to the pressure exerted on the core. The side-hole cane structure self-compensates and is insensitive to temperature variations when used as a pressure sensor, because temperature induces an equal shift in both the first and second wavelengths. Furthermore, the magnitude of these shifts can be monitored to deduce temperature, hence providing the side-hole cane additional temperature sensing capability that is unaffected by pressure. Additionally, the side-hole cane can be used to measure a differential pressure between a first pressure ported to the side-holes and a second external pressure.

Abstract: The present invention provides an anastomosis device which includes an elongate center pin having proximal and distal ends. The proximal end is configured to be graspable using a grasping tool. A grip mechanism is located at the distal end for crimping a suture. The device includes an outer sleeve having a passageway therethrough to receive therein the elongate center pin. A suture having a suture needle is attached to a first end of the center pin and a second end of the suture is formed into a pre-formed knot mounted on the sleeve. The device includes a suture release mechanism having a passageway extending therethrough to receive the outer sleeve therein. The suture release mechanism slides along the sleeve between a first position in which the suture release mechanism is spaced from the distal end and a second position such that movement of the suture release mechanism from the first position to the second position dislodges the pre-formed knot off the sleeve. A free end of the suture, which was attached to a suture needle but cut lose after the suture has been passed through the tissue being sutured, is crimped by the crimp mechanism. The pre-formed knot is dislodged such that the crimped end of the suture is located within the pre-formed knot and pulling the suture through the knot tightens the pre-formed knot on the suture.

Abstract: A multi-antenna transmitting entity transmits data to a single- or multi- antenna receiving entity using (1) a steered mode to direct the data transmission toward the receiving entity or (2) a pseudo-random transmit steering (PRTS) mode to randomize the effective channels observed by the data transmission across the subbands. The PRTS mode may be used to achieve transmit diversity or spatial spreading. For transmit diversity, the transmitting entity uses different pseudo-random steering vectors across the subbands but the same steering vector across an entire packet for each subband. The receiving entity does not need to have knowledge of the pseudo-random steering vectors or perform any special processing. For spatial spreading, the transmitting entity uses different pseudo-random steering vectors across the subbands and different steering vectors across the packet for each subband. Only the transmitting and receiving entities know the steering vectors used for data transmission.
