A blade set for paper shredders is disclosed. In one embodiment, a notched blade having at least two notches in proximity to a central hole is brought into contact with a mating blade also having a central hole. Force is applied to the mating blade in such a fashion as to displace some of the body of the mating blade into the notches. This acts to substantially secure the blades together. In another embodiment, the notches are disposed on the edge of the blade and through the periphery. In yet another embodiment, one blade can have holes and not notches.

The invention provides an energy storage system having storage elements linked for collective charging and discharging. Monitoring circuitry is provided for monitoring each of the storage elements independently. Preferably, the system includes control circuitry configured for controlling the linking of individual storage elements in order to enhance system performance. In preferred embodiments, the system also includes storage elements in an arrangement whereby they may be selectably linked and delinked, in series, parallel, or in one or more series/parallel combination.

The invention provides advances in the arts with useful and novel driver methods. The invention provides circuit driver and control methods for relatively high-current drivers, usable with relatively low-voltage battery power sources. Preferred embodiments include one or more high series resistance capacitors electrically connected with a power source. A low resistance driver circuit regulates power supplied from the capacitors to the load.

The invention provides advances in the arts with useful and novel methods for assembling multi-layer semiconductor structures having one or more internal conductive layers. The disclosed structures provide advantages in terms of resistance to Single Event Effects (SEE) particularly useful in electronics designed for radiation hardness. Disclosed methods include steps for providing two semiconductor layers, each having a conductive surface, and bonding them together with their conductive surfaces adjoining in order to form an internal conductive layer within a completed multi-layer structure. The conductive surfaces may include metals selected for their superior conductivity, refractory metals, selected primarily for their heat-resistance, or conductive dopants. In alternative embodiments, vertical interconnects are also included.

A system for receiving data is provided. The system includes an inductive data device, such as a device that receives high-speed data over an inductive coupling. An adjustable impedance is coupled to the inductive data device, where the adjustable impedance is used for dynamically controlling ringing in the inductive data device, such as by damping ringing signals generated by circuit inductances or capacitances.

The disclosed invention provides electrochemical dispensing apparatus and methods. According to the principles of the invention, a microelectronic electrochemical dispenser is used to cause the release of one or more selected chemical substance from a stored chemical compound. The release is controlled using a timer or sensor apparatus in a controlling device, preferably an ASIC.

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:
A method, for use for example in pension scheme defeasance, comprises providing to an entity a financial instrument which undertakes to pay to the entity, at regular points in time within a specified duration, sums according to a schedule of payment amounts associated with the financial instrument, the scheduled payment amounts being arranged to match with the expected cash flow obligations of a pension scheme to its members. At a re-set point in time the schedule of payment amounts is re-set such that the entity will receive an adjusted payment amount calculated to be the aggregate of nominal cash flows to be paid to the pension scheme members adjusted to take into account the actual cumulative mortality experience of the pension scheme prior to the re-set point in time. Calculations for carrying out the method may be made using a data processing system.

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.
