Abstract: Certain aspects of the present disclosure generally relate to methods and apparatus for decoding low-density parity check (LDPC) codes, for example, using a parity check matrix having full row-orthogonality. An exemplary method for performing low-density parity-check (LDPC) decoding includes receiving soft bits associated to an LDPC codeword and performing LDPC decoding of the soft bits using a parity check matrix, wherein each row of the parity check matrix corresponds to a lifted parity check of a lifted LDPC code, at least two columns of the parity check matrix correspond to punctured variable nodes of the lifted LDPC code, and the parity check matrix has row orthogonality between each pair of consecutive rows that are below a row to which the at least two punctured variable nodes are both connected.

Abstract: Additive layer manufacturing apparatus utilizing a housing, which bounds a vacuum chamber and has a window for monitoring a region of the chamber in which additive layer manufacturing is to be carried out, and an electron beam column for generating an electron beam and transmitting the beam through the chamber to the region for action on successive layers of fusible powder material, particularly metallic material, to produce an article therefrom. In order to combat the problem of deposition on the window of metal material escaping from the layer as gaseous phase constituents with a boiling point below the melting point of the material, an optical element is arranged in the chamber to intercept such liberated gaseous phase constituents, which in a vacuum environment in the chamber travel along an optical path between the region and the window, and optical element heating means substantially preventing condensation of the intercepted constituents.

Abstract: A compression garment for a limb is disclosed. The garment can include a body portion and a spine portion. Each of the body and spine portions can have a plurality of bands (e.g. bands for adjusting tension of the garment). The spine portion can be releasably attached onto the body portion such that the spine portion is positionable at different locations on the body portion to adjust a width of the garment. The bands of the body portion and/or of the spine portion can be trimmable and include a detachable fastener, whereby as a result the band can be caused to move to a plurality of different positions to adjust the garment to a plurality of different sized limbs (e.g. different sized feet).

Abstract: Aspects of the disclosure relate to wireless communication devices configured to generate polar codewords utilizing a single master sequence constructed using density evolution with a nested structure for identifying the frozen bit locations and information bit locations. This single master sequence may be used for any codeword length N up to a maximum codeword length Nmax, and may further be utilized for any code rate R. For example, from the master sequence of length Nmax, a bit location sequence S with codeword length N (where N<Nmax) may be obtained by selecting the bit locations (indexes) in the master sequence corresponding to each bit location in S in the order provided in the master sequence.

Abstract: Aspects of the present disclosure relate to low density parity check (LDPC) coding utilizing LDPC base graphs. Two or more LDPC base graphs may be maintained that are associated with different ranges of overlapping information block lengths. A particular LDPC base graph may be selected for an information block based on the information block length of the information block. Additional metrics that may be considered when selecting the LDPC base graph may include the code rate utilized to encode the information block and/or the lift size applied to each LDPC base graph to produce the information block length of the information block.

Abstract: A method of additive layer manufacture includes the steps of successively depositing layers of fusible powder material in overlying relationship and introducing energy, such as by an electron beam, into each deposited layer to selectively melt material in the layer so as to fuse the melted material together and to already fused material of a layer thereunder in order to produce a three-dimensional solid article in successive cross-sectional layers. In order to monitor layer quality, structured light defining a fringe pattern is projected onto each deposited layer before and/or after melting of material in that layer and the fringe pattern on each layer is imaged from a perspective different from that of the projection so as to reveal disturbance of the pattern by topographical features of the layer.

Abstract: Mobile devices are used as temporary location anchor points, e.g., to supplement fixed location permanent location anchor points, in a wireless communications system in which mobile device locations are determined. A mobile device receives a command or request to operate as a location anchor point. In some embodiments, the command includes time information indicating the amount of time the mobile device is to operate as a location anchor point. In some embodiments, a mobile device operating as a location anchor point reports a received signal strength measurement along with information identifying the device from which the signal was received to a network element, e.g., a location server node. In some embodiments, a mobile device operating as a location anchor point broadcasts a signal providing location information. The mobile device receives compensation for operating as a location anchor point. Compensation may be monetary, services, or benefits provided by the network.

Abstract: Various aspects of the disclosure relate to encoding information and decoding information. In some aspects, the disclosure relates to an encoder and a decoder for Polar codes with HARQ. If a first transmission of the encoder fails, information bits associated with a lower quality channel may be retransmitted. At the decoder, the resulting decoded retransmitted bits may be used to decode the first transmission by substituting the retransmitted bits for the original corresponding (low quality channel) bits. In some aspects, to decode the first transmission, soft-combining is applied to the decoded retransmitted bits and the original corresponding (low quality channel) bits. In some aspects, CRC bits for a first transmission may be split between a first subset of bits and a second subset of bits. In this case, the second subset of bits and the associated CRC bits may be used for a second transmission (e.g., a retransmission).
