A method of transmitting data in a communications system comprising a first station and a second station. The method for transmitting data in a communications system comprises encoding data; allocating the encoded data to different quality channels based on how data is encoded; and transmitting the encoded data on the allocated channels from the first station to the second station.

This invention relates to a method, device, computer program and computer program product for determining a mapping for a sequence of information-carrying values, including determining K representations of a sequence of information-carrying values in K successive stages, respectively, wherein in a first stage, a first representation of said K representations is determined to be equal to said sequence of information-carrying values, wherein in subsequent stages, each representation is determined by performing a mapping operation on the representation determined in the preceding stage, and wherein said mapping operation is the same for each stage; calculating, in each stage, a parameter from a transformation of the representation determined in said stage; and determining for which stage of said K stages an extreme value of said parameter is calculated. The invention further relates to a method, device, computer program and computer program product for inverse-mapping a mapped sequence of information-carrying values, and a system for the transfer of information-carrying values.

A method and device for capturing speckles are described. A highly coherent light emitted from a light source is used to illuminate a surface and produces scattered lights. The scattered lights pass through a light restrictive element and the diffracted lights produced by this restrictive element interfere with one another to generate a speckle pattern. An image sensor is then used to pick up the speckle pattern to form a speckle image. Therefore, the effects of diffraction and interference and a light restrictive element to enlarge the speckle size and reduce the variation of the speckle pattern during the movement of the imaging device are utilized, so that the speckle pattern can be clearly identified in the image. As a result, the method and device for capturing speckles are fairly stable and sensitive.

A phased array antenna module for use in the gigahertz bandwidth. The module includes a metallic core with a pair of chip carrier assemblies secured to opposite sides of the core. The core has an internal waveguide with a signal splitter for directing electromagnetic wave energy evenly to the two chip carrier assemblies. A flexible, cylindrical connector assembly electrically couples the chip carrier assemblies to an aperture board. The aperture board includes a plurality of dipole antenna radiating elements. The module core is coupled directly to a cold plate. A direct thermal path is created between the chip carrier assemblies, the module core and the cold plate for highly efficient cooling of the electronic components on the chip carrier assemblies.

A method, apparatus, and computer instructions are provided for expressing high availability (H/A) cluster demand based on probability of breach. When a failover occurs in the H/A cluster, event messages are sent to a provisioning manager server. The mechanism of embodiments of the present invention filters the event messages and translates the events into probability of breach data. The mechanism then updates the data model of the provision manager server and makes a recommendation to the provisioning manager server as to whether reprovisioning of new node should be performed. The provisioning manager server makes the decision and either reprovisions new nodes to the H/A cluster or notifies the administrator of detected poisoning problem.

A method, apparatus, and computer instructions are provided for a common cluster model for configuring, managing, and operating different clustering technologies in a data center. The common cluster model supports peer cluster domains and management server cluster domains. Each cluster domain may have one or more cluster nodes. For each cluster domains, one or more cluster resources may be defined. These resources may depend on one another and may be grouped into a resource group. A set of cluster domain and cluster resources logical device operations are provided to configure, manage, and operate cluster domains and its associated resources.

A system and method for a transceiver structure, where Different Known Guard Intervals (DKGI) are appended to multiple, consecutive data blocks and are then used in combination with Channel State Information (CSI) to restore cyclic convolution in the time domain. Once restored, the CSI and cyclic convolution are transformed into the frequency domain by FFT processing to facilitate equalization of the channel through Frequency Domain Equalization (FDE). Through performance of time domain channel estimation, there is no need for pilot signals and related overhead, thus channel capacity is enhanced.

A waveguide transition for use with an antenna aperture. The waveguide includes a tubular waveguide component with a concentrically disposed dielectric insert. In one embodiment the inner surface of the waveguide component is non-linear and formed by either a gradually curving surface or a plurality of linear sections disposed adjacent one another to form an overall non-linear surface when viewed in profile. In other embodiments the outer surface of the dielectric insert is shaped so as to form either a gradually curving surface or by a plurality of non-linear, adjacently formed sections that form an overall non-linear shape when the dielectric insert is viewed in profile. The waveguide of the present invention produces significantly improved cut-off frequency performance that allows a greater degree of flexibility in designing the antenna aperture with a desired operating frequency bandwidth.
