摘要:
An immersed membrane system or process may use measured or calculated process information to optimize one or more process operating parameters to improve performance or reduce operating costs. An on-line process control system or method may use the resistance in series method in operating an immersed membrane water treatment system. A process control system or process may consider resistance values and adjust operational parameters such as membrane aeration frequency factor, membrane aeration flow, permeate flux, permeation duration, backwash flow and duration, relaxation duration or maintenance or recovery chemical cleaning frequencies in order to reduce the operational costs related to membrane fouling removal.

Briefly, some embodiments of the invention provide devices, systems and methods for selective aggregation of transmission streams. For example, a method in accordance with an embodiment of the invention may include selectively aggregating a first transmission stream and a second transmission stream into an aggregated stream, based on a data-related characteristic of the first and second transmission streams.
摘要:
Briefly, a method and apparatus to estimate a collision rate parameter by manipulating a first probability value with a second probability value. The first probability value may be the probability of an attempt to transmit a data packet within a desired time slot of a contention window. The second probability value may be a probability of data packet transmitted from the desired time slot within the contention window to collide with an at least one other data packet transmitted by other station of wireless communication network.
摘要:
Briefly, a method and apparatus that may enable roaming of a station from a first access point to a second access point by presenting a power saving mode to the first access mode while establishing a secured connection with the second access point.
摘要:
An auditory assistance apparatus and method for use with a sound signal source which also produces a magnetic field propagated along a magnetic field axis to increase the signal-to-noise ratio with respect to ambient noise. A pair of magnetic pickup coils of substantially the same electrical and magnetic parameters, but of opposite polarity, are located close to the sound signal source and oriented symmetrically with respect to the geometrical axis of the auditory assistance apparatus with the magnetic axes of the pickup coils substantially parallel to each other and substantially perpendicular to the magnetic field axis of the sound signal source and the geometrical axis of the auditory assistance apparatus; and an amplifier which adds and amplifies the outputs of the serially-connected pickup coils and feeds same to an audio transducer for conversion to sound.
摘要:
Apparatus for determining a location of a target, the apparatus comprising: first and second magnetic dipole beacons positioned at substantially a same spatial location having respectively first and second time dependent magnetic moments oriented in different directions that generate first and second magnetic fields having different time dependencies; at least one magnetic field sensor coil located at the location of the target that generates signals responsive to the first and second magnetic fields; and circuitry that receives the signals generated by the at least one sensor coil and processes the signals responsive to the different time dependencies of the magnetic fields to determine a location of the at least one sensor coil and thereby the target.
摘要:
Embodiments of systems, apparatuses, and methods for performing in a computer processor vector packed horizontal partial sum of packed data elements in response to a single vector packed horizontal sum instruction that includes a destination vector register operand, a source vector register operand, and an opcode are described.
摘要:
Solvent and acid stable ultrafiltration and nanofiltration membranes including a non-cross-linked base polymer having reactive pendant moieties, the base polymer being modified by forming a cross-linked skin onto a surface thereof, the skin being formed by a cross-linking reaction of reactive pendant moieties on the surface with an oligomer or another polymer as well as methods of manufacture and use thereof, including, inter alia separating metal ions from liquid process streams.
摘要:
A processor may support a two-dimensional (2-D) gather instruction and a 2-D cache. The processor may perform the 2-D gather instruction to access one or more sub-blocks of data from a 2-D image stored in a memory coupled to the processor. The 2-D cache may store the sub-blocks of data in a multiple cache lines. Further, the 2-D cache may support access of more than one cache lines while preserving a 2-D structure of the 2-D image.
