Title: Improvements in switch mode power supply
Inventor: RAYMOND JOHN PETO
IPC: H02P27/08
Filed: 2016-06-30
Abstract: A passive switch mode power supply (SMPS) has a main circuit 300 and a passive circuit 304 for reducing current ripple flowing in a main inductor 207 in the main circuit. The passive circuit is operable, so that when a switch 205 in the main circuit is closed for a time period the closed switch prevents current in the passive circuit from flowing in a main inductor. The passive circuit is then operative so that current flows in the passive circuit in a first direction in an auxiliary inductor 302 so that energy is transferred from the auxiliary inductor to an auxiliary capacitor 301. During a subsequent time period current flows in a direction which is opposite to the first direction so that energy is transferred from the auxiliary capacitor to the auxiliary inductor. The exchange of energy to/from auxiliary inductor and capacitor acts to conserve energy whilst permitting reversal of current direction. During subsequent time periods current flows to/from the passive circuit thereby compensating current in the main inductor and so reduces current ripple in the main inductor.

Abstract: A nano- or micro-scale therapeutic agent is provided for use in the treatment of an infection of a human or animal. The agent comprises micro- and/or nano-particle carriers loaded singly or in combination with at least one inert precursor chemical. The carriers encapsulate the precursor chemical or chemicals which after release from the carrier are activatable by the physiological milieu in situ at the site of the infection to form an antimicrobial agent. Preferably, the precursor chemical or chemicals form an oxidative biocide on release, which oxidative biocide is hydrogen peroxide. Advantageously, the precursor chemicals also comprise an acetyl donor that on release reacts with the hydrogen peroxide produced by the peroxygen donor to produce a mixture of peracetic acid and hydrogen peroxide. The carrier is preferably in the form of micro- and/or nano-particles that have been manufactured using a thermally induced phase separation (TIPS) process, for example the carrier may comprise a biodegradable polymer such as poly(lactic-co-glycolic acid) (PLGA).

Title: Method to reduce complexity in flow noise calculation
Inventor: DRASKO MASOVIC
IPC: G06F17/50
Filed: 2017-03-07
Abstract: Disclosed is a method of predicting sound diffraction a sharp body, such as a trailing edge, in low Mach number flows. The method starts by checking the applicability of the method by analysing the flow and geometry, to give the Mach number, (<0.3) and Helmholtz Number (<0.5). Next, the computational fluid dynamic (CFD) model is discretised based on the set boundary and initial conditions. Then the velocity and temperature profile of the flow is determined by the CFD calculations. Next, the acoustic computational domain is discretised, with setting the boundary conditions, the initial conditions and loads (sound sources). The critical computational nodes at the sharp edges are identified, and the acoustic sink at the critical nodes is determined according to the relationship Pic = - Mp. The stiffness matrix is then modified using Kij = (2 + Mi)Kij and the resultant system of equations is then solved.

Title: Structuring a finance agreement to include an insurance component appendix to hedge against risk
Inventor: ROBIN POINTER
IPC: G06Q40/08
Filed: 2017-03-09
Abstract: Method for providing financial asset protection for a project, by creating a Risk Transfer Structure to protect the assets, revenue stream(s), including but not limited to protection of Lender(s) interest and principal payment obligations, and liabilities of the Business/Borrower by providing a strategy that contractually hedges risk at all levels of a funded project, thereby limiting potential exposures to the Borrower and Lender, without negatively impacting the overall financial condition of the Business or its ability to meet its financial obligations. An insurance policy provides, by contract, language and a template that allows the primary insurer and reinsurer to act as the Lender for specific projects and pays financial asset Lender(s) for their loan amount through an all risk policy. This reduces the need for the servicer to engage in additional investing in order to hedge against default risks during the life of the loan.
