Title: Implantable signal amplifying circuit for electroneurographic recording
Inventor: BARU FASSIO MARCELO DANIEL
IPC: A61B5/04
Filed: 2002-04-19
Abstract: An implantable microvolt-level signal amplifying circuit may be used for resolving electrical signals generated by nerves in the presence of larger amplitude signals generated by muscles, the heart, or external noise sources. The circuit has a low-noise, high Common Mode Rejection Ratio (CMRR) preamplifier, followed by a cascade of stages, which provide filtering and further amplification of the neural signal. The band-pass amplifying circuit can also present high Power Supply Rejection Ratio (PSRR). The output is offset-compensated by a DC restoration stage. Nerve protection circuitry minimizes or blocks DC current flow through the input terminals in the event of semiconduc-tor failure in the preamplifier. The circuit may be incorporated onto a common monolithic circuit with follow-up circuitry for controlling Functional Electrical Stimulation (FES) devices.

Title: Apparatus for and method of secure atm debit card and credit card payment transactions via the internet
Inventor: HODGSON ROBERT B
IPC: G06Q20/00
Filed: 2000-08-25
Abstract: The present invention is directed to a combination software and/or hardware system that provides consumers and merchants with a secure method for making and accepting credit card and ATM card payments over the Internet. Using various software and/or hardware implementations, the system operates by: 1) creating (at the consumer's Internet access device) a Data Encryption Standard (DES) encrypted Personal Identification Number (PIN) Block meeting American National Standards Institute (ANSI) X9.8 and Automatic Teller Machine (ATM) network requirements (as a result of the consumer entering their PIN number and encryption automatically taking place); 2) using additional layer(s) of encryption (also performed at the consumer's Internet access device) to place the PIN  block and card information in a public key/private key encrypted financial payment transaction data block ("FP Block"); 3) transmitting the FP Block to the merchant, along with any necessary product or service order information, which may be transmitted over the Internet encrypted or in the clear according to the implementation method chosen by the system software at the merchant's web site; 4) software at the merchant location then forwards the FP Block to a secure transaction management system, where the FP Block is decrypted using a decryption algorithm matching that used by the software at the consumer's Internet access device. The financial data is then re-formatted for transmission to the appropriate transaction processing network, and forwarded to the payment service processor accordingly.  The present invention is independent of the encryption algorithm(s) used, and may be implemented with any number of encryption algorithms.
