An asynchronous,low-power architecture for interleaved neural stimulation, using envelope and phase information
… low-power cochlear-implant processor chip and a charge-balanced stimulation chip that together form a complete processing-and-stimulation cochlear-implant system. The processor chip uses a novel Asynchronous Interleaved Stimulation (AIS) algorithm that preserves phase and amplitude cues in its …

Tear and skin phospholipids:analysis and hydrogel analogues
… with 2-hdyroxyethyl methacrylate (HEMA). Charge-balanced membranes were also synthesised using potentially anionic monomers in conjunction with cationic monomers in stoichiometrically equivalent ratios also with HEMA as a commoner. Membranes of SPDA copolymers and charge-balanced …

A system for electrical retinal stimulation for human trials
… shock. The stimulation system delivers charge balanced current pulses to the 100 electrodes in the array. The system has been tested in the laboratory setting as well as in rabbit experiments and one human retinal stimulation trial. It functions as specified, and is very robust.

Development of a Parallel Hybrid Energy Management Strategy with Consideration of Drive Quality and State of Charge Dynamics
… Algorithms are proposed for battery state of charge (SOC) management including engine loading and one pedal strategies. Vehicle drive quality with the hybrid control strategy is analyzed, with acceleration and jerk managed through axle torque rate limits and filters. The simulated control …

Understanding the challenges in HEV 5-cycle fuel economy calculations based on dynamometer test data
… because although they are required to have charge-balanced batteries over the course of a full drive cycle, they may have net charge or discharge within the individual phases. The fundamentals of studying battery charge-balance are discussed in this paper, followed by a detailed …

Coordination Cages as a Scaffold for Permanently Porous Liquids
… we define to be a coordination cage that is charge-balanced by a second, different cage of opposite charge. A hetero-cage was synthesized by charge-balancing a liquid coordination cage with +20 charge with 5 equivalents of a solid anionic cage with -4 charge. The resulting material was …

Nominally volatile-free mantle minerals: a reservoir for water and fluorine in the Kaapvaal Craton
… is recognised: Ti4+ in an octahedral site is charge balanced by F− in an oxygen site and OH− in a neighbouring tetrahedral vacancy. This triple coupling limits the independent diffusion of each element and hence preserves metasomatic enrichment on timescales of millions to billions of years. …

A Variable Gain Direct Digital Readout System for Capacitive Inertial Sensors
High fidelity interface circuits for capacitive accelerometers make use of feedback for signal detection but these feedback systems are limited by the sense capacitance and sensitivity of the accelerometers. This problem is addressed by a variable gain delta sigma based interface circuit that time …

Grain boundary chemistry and morphology of heavily doped cerium dioxide
… transmission electron microscope (STEM). Space charge models both at the dilute limit, and with a limited site density at the interface, have been applied. In addition, a number of adsorption models have been considered. The segregation isotherms of singly doped compositions allow one to …

Synthesis of Inorganic-Organic Hybrid Materials Designed For Radiation Detection, Luminescence, and Gas Storage
… (POM) containing a typical Keggin ion, which is charge-balanced via protonated organic ligands. POMs are one of the most studied inorganic clusters owing to their potential catalytic capabilities. A third part concerns a pseudo hybrid material consisting of boron, a metalloid, and a polymeric …

A prototype dynamic model for the co-treatment of a high strength simple-organic industrial effluent and coal-mine drainage
… The prototype model is presented in a mass and charge balanced Gujer matrix that includes, i) 5 SRB mediated processes, ii) 2 liquid-gas mass transfer processes, iii) 3 processes describing the ABS and Fe2+ bio-oxidation units, iv) 4 processes describing sulfide and elemental sulfur oxidation …

Synthesis and characterisation of Aurivillius phase materials
… to maintain a material with a net neutral charge. For the material Bi5Ti3-2xFe1+xNbxO15 (x = 0, 0.1, 0.2, 0.3 and 0.4) a solubility limit of x = 0.1 was found before the appearance of secondary impurity phases became apparent. The increased iron content resulted in an increased absorption …
