摘要:
The invention provides integrated power supplies, circuit drivers, and control methods for relatively high-current drivers, usable with common battery power sources. Preferred embodiments include one or more high series resistance super-capacitors electrically connected with a power. A low resistance driver circuit regulates power supplied from the super-capacitors to the load.

An AC to DC converter system is disclosed in which a conversion circuit for converting an AC input signal to a DC output signal is operably coupled with an enabling circuit designed for sensing and output parameter indicative of the presence or absence of a load at the DC output. The system is designed so that the conversion circuit operates in an inactive standby state when there is no load, and in an active state for supplying DC power when a load is present. The enabling circuit is configured to operate using low power.

There is provided a computer-implemented method of projecting the future cash flows of a pension scheme, comprising: receiving data representative of the members of the pension scheme; receiving data representative of a mortality assumption; calculating, using data processing apparatus, for each pension scheme member, a projection of the future cash flow liabilities of the pension scheme to that member on the basis of the pension scheme member data and by applying the mortality assumption data to the pension scheme member data; and generating, using data processing apparatus, data representative of a projected liability cash flow of the pension scheme to all of its members by aggregating the liabilities to each member.
摘要:
Multiple coil systems and methods are disclosed in which transmitter and receiver inductors, or coils, are coupled in a configuration for wirelessly transferring data and/or power among them. In preferred implementations, the systems and methods are used for transmitting both power and data using pairs of coupled coils. One preferred aspect of the invention is that the coils are not permanently affixed in physical proximity to one another, but can be moved and/or interchanged.

A transceiver interface is disclosed in which a true positive node and a true ground node are maintained with three adaptive terminals. The adaptive terminals each have pairs of isolation elements linking them to the true positive node and true ground node, whereby, each of the adaptive terminals can function as a positive terminal, ground terminal, and transceiver terminal, in response to how the interface is connected to external equipment.

There is provided a method of securitizing a pension fund associated with a pension scheme, comprising: calculating, using data processing apparatus, the expected liabilities of a pension scheme to at least a portion of its members taking into account an expected mortality of the scheme members; issuing from a securities issuing entity a financial instrument which undertakes to pay to an investor a cash flow according to a payment schedule, said expected liabilities being establishing as the initial payment schedule of a financial instrument; exchanging financial instrument with assets held by pension fund; and supporting the securities issuing entity in issuing the financial instrument by providing risk capital to the securities issuing entity; wherein the risk capital is initially provided by at least three separate equity investor entities. One of the equity investor entities may be the corporate sponsor of the pension scheme. Alternatively the risk capital is initially provided by the corporate sponsor of the pension scheme.

There is provided a computer-implemented method of estimating a capital reserve requirement to cover the longevity risk exposure of a financial instrument in the case of a future longevity shock, the financial instrument undertaking to pay to an investor sums according to a payment schedule of amounts arranged to match with the future cash flow obligations of a pension scheme to at least a portion of its members. The method comprises: (a) calculating, using computing apparatus, an expected payment schedule of the financial instrument by calculating what the cash flow obligations of the pension scheme to its relevant members would be in the case of an expected longevity scenario for the pension scheme membership occurring; (b) calculating, using computing apparatus, a present value of the financial instrument in the case of a stressed longevity scenario for the pension scheme membership in which a longevity-related shock to the expected longevity scenario of the pension scheme membership occurs; and (c) calculating, using computing apparatus and using the calculations of the expected payment schedule and a present value of the financial instrument in the case of a stressed longevity scenario, an estimate of the longevity capital reserve required to ensure that the future cash flow obligations of the financial instrument would be covered in the event that the stressed longevity scenario were to occur.
摘要:
The radiation beam of discrete light source such as LEDs is shaped by a cylindrical lens and a spherical lens to form two perpendicular narrow lines to illuminate a surface. The first line is projected onto a sample surface to improve illumination efficiency, and the second line is projected onto a pupil plane of an imaging lens to improve illumination uniformity. The layout of the LED chip is optimized to match the aspect ratio of the imaging detector. Multiple LEDs at different wavelengths are combined to improve sensitivity. The full surface of the sample is inspected through the relative motion between the sample and the optics.
