System, method, and computer program product for selecting and presenting financial products and services

An apparatus and method are provided which use client information from a client to automatically select and present financial products appropriate for the client. The apparatus according to one aspect of the invention comprises an input device for inputting client information relevant to a need by the client for the financial products, for inputting information about the financial products, for inputting ancillary data which excludes the client information and the financial products information, and for inputting decision criteria pertaining to selection from among the financial products. The apparatus further includes a storage device for storing the client information, the financial products information, the ancillary information, and the decision criteria. The apparatus still further includes decision making logic circuitry for using the client information, the financial products information, the ancillary information, and the decision criteria to select a subset of the financial products. It further includes an output device for preparing a client communication which identifies the subset of the financial products. The output device incorporates a portion of the client information and a portion of the financial products information into the client communication. The method according to one aspect of the invention comprises inputting client information relevant to a need by the client for the financial products, inputting information about the financial products, inputting ancillary data which excludes the client information and the financial products information, and inputting decision criteria pertaining to selection from among the financial products. The method also includes storing the client information, the financial products information, the ancillary information, and the decision criteria. This method further includes using the client information, the financial products information, the ancillary information, and the decision criteria to select a subset of the financial products. It further includes preparing a client communication which identifies the subset of the financial products. This client communication preparing step includes incorporating a portion of the client information and a portion of the financial products information into the client communication.

Switch circuit and method of switching radio frequency signals

A novel RF buffer circuit adapted for use with an RF switch circuit and method for switching RF signals is described. The RF switch circuit is fabricated in a silicon-on-insulator (SOI) technology. The RF switch includes pairs of switching and shunting transistor groupings used to alternatively couple RF input signals to a common RF node. The switching and shunting transistor grouping pairs are controlled by a switching control voltage (SW) and its inverse (SW_). The switching and shunting transistor groupings comprise one or more MOSFET transistors connected together in a “stacked” or serial configuration. The stacking of transistor grouping devices, and associated gate resistors, increase the breakdown voltage across the series connected switch transistors and operate to improve RF switch compression. A fully integrated RF switch is described including digital control logic and a negative voltage generator integrated together with the RF switch elements. In one embodiment, the fully integrated RF switch includes a built-in oscillator, a charge pump circuit, CMOS logic circuitry, level-shifting and voltage divider circuits, and an RF buffer circuit. Several embodiments of the charge pump, level shifting, voltage divider, and RF buffer circuits are described. The inventive RF switch provides improvements in insertion loss, switch isolation, and switch compression.

Method and apparatus for testing error detection

Disclosed is a device and method for testing of a program or a design of an electronic device comprising digital logic circuitry. The method comprises testing the design of software or an electronic device and injecting, after initiation of the testing step, a predetermined error pattern into a value operated upon by the design of the digital logic circuitry. In a preferred embodiment, the software is a simulation of the design of a processor having a cache with error detection and/or correction circuitry. A triggering condition is preferably a cache hit, in response to which a detectable error is injected into the cache. The simulated operations of the model are observed to determine whether the injected error is detected, as should happen if the processor's error detection circuitry has been designed properly. In another respect, the invention is an apparatus, or computer software embedded on a computer readable medium, for testing a program comprising an error detector. The apparatus or software comprises the program, an error injector module connected to the program; and a checker module connected to the program. The checker module is capable of determining whether the program responds appropriately to an error dynamically produced by the error injector module during execution of the program. By injecting errors dynamically the invention easily facilitates precisely focused testing at any time during simulated operation regardless of initialization conditions.
