Filed:

Dec 7, 2001

Appl. No.:

10/013284

Inventors:

Qi Li - Fremont CA

Assignee:

Highpoint Technologies, Inc. - Fremont CA

International Classification:

H03K 19018

US Classification:

326 75, 326 66, 326 67, 326 73, 326 77, 326 78

Abstract:

An improved ECL circuit, based upon an ECL circuit of conventional design, functions as the required transceiver for the bi-directional data transmission between a computer and an electronic device with a specific interface of USB 2. The value of an emitter resistor within an emitter resistance network in the conventional ECL circuit is adjusted till its output voltage amplitude meets the USB 2. 0 specification. A number of voltage level shifting and capacitive coupling circuits are added to both the input and output sections of the conventional ECL circuit making it directly interfaceable with the popular CMOS logic family. A collector electrode switch network is also added to the conventional ECL circuit to make its output terminals tri-statable thus compatible with the communication scheme of half duplexing under the USB 2. 0 specification.

Abstract:

Systems and related methods facilitating secure payments are discussed herein. Some embodiments may provide for a system including a payment gateway server, a tokenizer server and a detokenizer server. The payment gateway server may receive payment card data from a merchant device and provide the payment data the tokenizer server. The tokenizer server may be configured to generate one or more tokens based on the payment data and provide the one or more tokens to the payment gateway server. During payment processing, the payment gateway server may be configured to provide the one or more tokens to the detokenizer server configured to determine the payment data based on the one or more tokens to facilitate completion of a financial transaction. In some embodiments, the one or more tokens may be stored for subsequent payments. Furthermore, some embodiments may provide for secure promotion redemptions in addition or alternative to payments.

Abstract:

Embodiments of the present invention provide improved methods, techniques, and systems to compute relevant and useful information that may be presented to users in an understandable, intuitive, and actionable platform. The interactive platform includes a format and visualization that is capable of presenting data for a wide range of protocols and topologies at various functional layers of the network. The interactive platform provides selectable categories of filters which update the network data and views displayed to the users to aid in the analysis and investigation of potential root causes of problems, rather than merely presenting examples of symptoms. The interactive platform includes a method and visualization that is capable of presenting differences in network behavior at various functional layers of the network.
