The present invention provides an a electronic payment system for bank, financial institutions, portals and companies to receive payment from their customers for one or more payees. The electronic payment system allows payer (consumer or business) to use any funding method (bank account, credit / debit cards or any other business or personal account or method associated with one or more banks) accepted by the payee to initiate a payment and the payment transaction is routed to the appropriate payment processor based on payee's preferences. The electronic payment system also provides a instant payment delivery notification to the payer directly from the payee. The system also creates a unique payment tracking number which can be used by all parties associated with the transaction to track a payment's status and other attributes associated with the payment. The electronic payment system also provides a rule based payment management system for the payees to use for managing the processing and posting of the payments. The system also allows for payees to manage their payments received and post to various receivable systems based on rules defined. Additionally, the system allows payees to create rules for other aspects of payment processing. The system also allows for much simplified electronic bill delivery system which uses biller's existing infrastructure to create bill data for distribution to 3rd party consolidators.

This invention relates generally to a system for processing database queries, and more particularly to a method for generating high level language or machine code to implement query execution plans. The present invention provides a method for generating executable machine code for query execution plans, that is adaptive to dynamic runtime conditions, that is compiled just in time for execution and most importantly, that avoids the bounds checking, pointer indirection, materialization and other similar kinds of overhead that are typical in interpretive runtime execution engines.

The elevation mechanism comprises a first pair of arms and a second pair of arms, with both the pairs of arms mounted relative to the patient support and the base. The first pair of arms and the second pair of arms have pivot connections at the patient support, with the pivot connections of at least one pair of the pair of arms moving in a sinusoidal path when the patient support is raised or lowered with respect to the base.

NAND architecture Flash memory strings, memory arrays, and memory devices are described that utilize depletion mode floating gate memory cells. Depletion mode floating gate memory cells allow for increased cell current through lower channel rdS resistance and decreased “narrow width” effect, allowing for increased scaling of NAND memory cell strings. In addition, the required voltages for reading and programming operations are reduced, allowing the use of more efficient, lower voltage charge pumps and a reduction circuit element feature sizes and layouts. Cell inhibit of unselected cells is also increased, reducing the likelihood of cell disturb in the memory array. Operation speed is improved by increasing read current of the selected NAND string and by increasing the ability to overcome the RC time constants of circuit lines and capacitances through lowered voltage swings and increased current supplies.

An auto-focusing method and device are presented for determining an in-focus position of a sample supported on a substrate plate made of a material transparent with respect to incident electromagnetic radiation. The method utilizes an optical system capable of directing incident electromagnetic radiation towards the sample and collecting reflections of the incident electromagnetic radiation that are to be detected. A focal plane of an objective lens arrangement is located at a predetermined distance from a surface of the substrate, which is opposite to the sample-supporting surface of the substrate. A continuous displacement of the focal plane relative to the substrate along the optical axis of the objective lens arrangement is provided, while concurrently directing the incident radiation towards the sample through the objective lens arrangement to thereby focus the incident radiation to a location at the focal plane of the objective lens arrangement. Reflected components of the electromagnetic radiation to a location objective lens arrangement are continuously detected. The detected reflected components are characterized by a first intensity peak corresponding to an in-focus position of said opposite surface of the substrate, and a second intensity peak spaced in time from the first intensity peak and corresponding to an in-focus position of said sample-supporting surface of the substrate. This technique enables imaging of the sample when in the in-focus position of the sample-supporting surface of the substrate.
