Abstract: Techniques of transmitting wireless communications involve generating orthogonal spreading codes for any number of user devices that are linear combinations of sinusoidal harmonics that match the frequencies within the spread bandwidth. Along these lines, prior to transmitting signals, processing circuitry may generate a set of initial code vectors that form an equiangular tight frame having small cross-correlations. From each of these rows, the processing circuitry produces a new spreading code vector using a code map that is a generalization of a discrete Fourier transform. The difference between the code map and a discrete Fourier transform is that the frequencies of the sinusoidal harmonics are chosen to match the particular frequencies within the spread bandwidth and differ from a center frequency by multiples of the original unspread bandwidth. Different transmitters may then modulate respective signals generated with different spreading code vectors.

Abstract: Methods, systems and apparatuses for providing high electrical resistance for an upper control assembly (including control handles) of an aerial lift are provided through an isolation member that is integral to the upper control assembly and interposed between fluid lines in the control assembly and a set of fluid conduits that extend from the control assembly towards other portions of the aerial lift. The isolation member is a dielectric element that comprises a manifold that is made of material that is substantially electrically non-conductive, and that has a plurality of through-holes or hoses configured to allow hydraulic fluid to flow through the isolation member into and out of the fluid lines and conduits. These methods, systems and apparatuses are preferably used in upper control assemblies of aerial platforms that can carry one or more operators in order to prevent such operators from electrocution when controlling the lift.

Abstract: A block copolymer useful in electron beam and extreme ultraviolet photolithography includes a first block with units derived from a base-solubility-enhancing monomer and an out-of-band absorbing monomer, and a second block having a low surface energy. Repeat units derived from the out-of-ban absorbing monomer allow the copolymer to absorb significantly in the wavelength range 150 to 400 nanometers. When incorporated into a photoresist composition with a photoresist random polymer, the block copolymer self-segregates to form a top layer that effectively screens out-of-band radiation.
