摘要:
A wireless telecommunications system including a base station, a terminal device, and a radio interface having a downlink radio frame structure including radio subframes including an arrangement of reference symbols for channel estimation. The base station determines a time period when certain terminal device specific data are not scheduled for transmission to the terminal device and communicates this information to the terminal device through selective suppression of at least one reference symbol. Different reference symbols may be suppressed to indicate different time periods. The terminal device monitors the transmitted reference symbols to identify where reference symbols are suppressed, to determine a time period when the terminal device is not expected to receive certain types of data and enter a reduced activity mode for that period, to conserve processing and power resources, and provide fast physical-layer signaling of periods during which the terminal device may conserve resources by decoding fewer transmissions.

A method and apparatus for blending liquids and granular materials in which an impeller assembly (27) is mounted for rotation within a housing (20) at a lower end (13) of a particles inlet (12) and characterized in particular by circumferentially spaced impeller vanes (28) in outer concentric relation to a series of expeller vanes (29, 29') surrounding the particles inlet and which together propel the solid particles outwardly to intermix with the liquid introduced into the annulus surrounding the impeller assembly, and different selected vane configurations (52, 61) are provided with circumferential portions protruding into the path of counterflow of the slurry from the annulus in order to keep the eye or central area of the impeller assembly dry.
摘要:
A computer implemented method for automatically detecting variations and/or abnormalities in the developmental conditions of in vitro incubating embryos, the method comprising the steps of: a) obtaining a first dataset comprising morphokinetic parameters relating to the development of a first group of embryos, b) obtaining a second dataset comprising morphokinetic parameters relating to the development of a second group of embryos, c) modifying the first and second datasets by extracting morphokinetic parameter outliers from the first dataset and or the second datasets, d) calculating the difference between specific morphokinetic parameters from the modified first dataset and the corresponding morphokinetic parameters from the modified second dataset, and monitoring said morphokinetic difference thereby detecting variations in the developmental conditions of the first and second group of embryos.
摘要:
Methods for determining a development potential for an embryo, for example an in vitro incubating human embryo, and apparatus for implementing such methods are described. In some examples a method comprises obtaining values for a plurality of morphokinetic characteristics relating to the development of an embryo during an observation period, for example characteristics relating to the temporal or morphological development of the embryo. A value for a continuous variable is determined by combining differences between the obtained values for these characteristics and corresponding reference values in a predefined manner. The reference values may, for example, be determined from values for the plurality of characteristics obtained for at least one reference embryo of known development potential. A development potential for the embryo is then established based on the determined value for the continuous variable.
摘要:
The present invention relates to a method and to a system for selecting embryos for in vitro fertilization based on observed cell kinetics and cell morphology. One embodiment of the invention relates to a method for determining embryo quality comprising monitoring the embryo for a time period, said time period comprising the transformation of the embryo from initial compaction or morula to blastocyst and determining one or more blastocyst quality criteria for said embryo, and based on said one or more blastocyst quality criteria determining the embryo quality.
摘要:
A wireless telecommunications system including at least one base station, a first terminal device and a second terminal device, wherein the first terminal device is a terminal device of a first type and the second terminal device is a terminal device of a second type, the second type being different from the first type, and wherein the at least one base station is configured to communicate data which is specific to the first terminal device in a synchronous manner and to communicate data which is specific to the second terminal device in a non-synchronous manner.
摘要:
A two-dimensional capacitive touch sensor having a cover layer of varying thickness arranged on top of its electrode structure. An array of sensing nodes is formed between edge portions of the receiver electrodes and adjacent portions of the transmitter electrodes. To compensate for the varying thickness of the cover layer, the length of the edge portions per sensing node is varied to equalize node sensitivity across the sensor and thus suppress the systematic variation in node sensitivity which would otherwise arise as a result of the varying thickness of the cover layer.
摘要:
The present invention relates to a method and to a system for selecting embryos for in vitro fertilization based on the timing, and duration of observed cell cleavages and associated cell morphology. One embodiment of the invention relates to a method for determining embryo quality comprising monitoring the embryo for a time period, and determining one or more quality criteria for said embryo, wherein said one or more quality criteria is based on the extent of irregularity of the timing of cell divisions when the embryo develops from four to eight blastomeres, and/or wherein said one or more quality criteria is based on determining the time of cleavage to a five blastomere embryo (t5) and wherein t5 is between 48.7 hours and 55.6 hours, and/or wherein said one or more quality criteria is based on the ratio of two time intervals, each of said two time intervals determined as the duration of a time period between two morphological events in the embryo development from fertilization to eight blastomeres, and based on said one or more quality criteria determining the embryo quality.
摘要:
A pack (1) for smoking articles is disclosed. The pack includes a body having two minor side walls, a minor top wall and a minor bottom wall extending between two opposing major walls so as to define a space for holding smoking articles. The pack (1) further includes an opening in at least one minor wall so as to provide access to the space, a lid (4) that is pivotally attached to the minor wall formed with the open¬ ing so as to open and close said opening. The lid (4) is attached to one of said minor walls along a hinge line (17) that extends obliquely relative to a plane of at least one of the major walls.
