Abstract: A computer-implemented method applies labels to unlabeled public data for use by a global model. One or more processors train one or more local machine learning models with local private data to create one or more trained models. Processor(s) generate a label for each of the local private data using the one or more trained models, where each label describes the local private data, and then apply the label to unlabeled public data to create labeled public data. One or more processors then input the labeled public data into a global model that uses the public data.

Abstract: Embodiments of the present disclosure relate to a new approach for image orientation detection. In the computer-implemented method, at least one character area in an image is sampled. The orientation of the sampled character area is determined, and the orientation of the image is determined based on the determined orientation of the sampled character area.

Abstract: Aspects of the present disclosure relate to a safety mechanical barrier for use with a ladder for an above-ground swimming pool that is easy to install and provides safety from children accessing the pool via the ladder. Certain aspects of the present disclosure relate to a safety mechanical barrier that blocks access to the ladder itself, thereby restricting access to an above-ground pool by unsupervised minors.

Abstract: Systems and methods for OFDM channelization are provided that allow for the coexistence of sub-band channels and diversity channels. Methods of defining diversity sub-channels and sub-band sub-channels are provided and systematic channel definition and labeling schemes are provided.

Abstract: Methods and systems are described that are suitable for channelization, in particular, but not limited to, the IEEE 80216.m telecommunications standard. For a time-frequency resource, physical sub-carriers for each of one or more zones in the time-frequency resource are assigned to one or more zones having a respective type of transmission. At least one zone is allocated for a type of transmission using localized sub-carriers. The physical sub-carriers assigned to each zone are permuted to map to logical sub-carriers. Groups of resource blocks are formed, in which each resource block includes at least one logical sub-carrier for each of the one or more zones. The information defining the groups of resource blocks for each of the one or more zones can then be transmitted to a user. The information may be in the form of a zone configuration index.

Abstract: Methods described herein are for wireless communication systems. One aspect of the invention is directed to a method for a HARQ process, in which the HARQ process includes a first transmission of an encoder packet and at least one retransmission. The method involves allocating a transmission resource for each respective transmission. The method involves transmitting control information from a base station to a mobile station for each respective transmission. The control information includes information to uniquely identify the HARQ process and an identification of one of a time resource, a frequency resource and a time and frequency resource that is allocated for the transmission. In some embodiments of the invention, specific control information is signalled from a base station to a mobile station to enable RAS-HARQ operation. In some embodiments of the invention, retransmission signaling in included as part of regular unicast signaling used for both first transmission and retransmissions.

Abstract: A codebook C is provided in a MIMO transmitter as well as a MIMO receiver. The codebook C will include M codewords ci, where i is a unique codeword index for each codeword ci. Each codeword defines weighting factors to apply to the MIMO signals, and may correspond to channel matrices or vectors to apply to the MIMO signals prior to transmission from the respective antennas of the MIMO transmitter. The present invention creates codeword subsets Si for each codeword ci of the codebook C. Each codeword subset Si defines L codewords cj, which are selected from all the codewords ci in the codebook C. The codewords cj in a codeword subset Si are the L codewords in the entire codebook that best correlate with the corresponding codeword ci.
