摘要:
An analog digital converter with switched-capacitor reset architecture. The analog to digital converter (ADC) includes a plurality of pipelined stages, each stage including an analog to digital converter comprising a pair of comparators outputting signals to a multiplying digital to analog converter (MDAC). The MDAC includes an opamp and a reset circuit connected to inputs of the opamp, the reset circuit including first and second capacitors and switching circuitry for precharging each of the first and second capacitors to a difference between the input and output common-mode voltages of the opamp, and during a reset phase of the MDAC, connecting the first capacitor between a positive input and a negative output of the opamp and connecting the second capacitor between a negative input and a positive output of the opamp to reset the opamp.

A Computer-Telephony Integration (CTI) system is used to control an Automatic Call Distribution (ACD) system, and non-ACD phone functions, where all functions can be performed at either the phone or the computer display by creating a Bidirectional CTI Model (BCM) in software. The ACD system is used in call centers to route incoming calls to call takers according to attributes such as dispatcher skill-sets or time since last call received. The ACD system is also able to send a call to a dispatcher without ringing, using an auto-answer system. The CTI system allows telephone functions such as originating calls, answering calls, and hold, transfer, and conference features to be controlled by a computer workstation.

摘要:
A computer implemented system and method for requesting, gathering, evaluating, and scoring knowledge. The system includes a first user interface for allowing a first group of users to define prompts and response choices, a second user interface for allowing a second group of users to view prompts and select response choices and view prompts without response choices and enter responses, and a third user interface for allowing a third group of users to evaluate previously-entered response by viewing the responses and selecting response choices. The system may automatically score the responses of the second group using scoring elements embedded in the response choices. The system may also include a relational database of related tables for storing the prompts, response choices, responses, evaluations, and user information. The system may also limit a user's access to various records based on the user's profile or a user responsibility associated with the user.
摘要:
A system for realizing improved fuel efficiency and reduced fuel emissions in an internal combustion engine. The system comprises a nano-jet filter includes a fuel channeling chamber having a set of aligned magnetic members such that the flow of fuel passes through a magnetic field created by the set of aligned magnetic members. The system further comprises a nano-jet saver, having a chamber equipped with additional sets of magnets in order to magnetize larger fuel molecules and traverse hyper magnet gradients. The purpose of using a hyper magnetic field is to change conventional fuel into “nano” fuel. Having fuel particles with a smaller diameter, both better fuel efficiency and reduced emissions are achieved as the fuel burns more completely and more cleanly. With any fossil-fuel internal-combustion engine, an operator can expect to see a reduction in emissions to the environment, fuel savings, and better performance while using an apparatus that consumes no external energy.

A beverage fountain includes a container and removable freezable member for containing and chilling a beverage. The removable freezable member is placed in or above the interior of the beverage container, in the flow path of a beverage circulating through the fountain to lower the temperature of the beverage. The removable freezable member is maintained in a position within the flow path without disrupting or interfering with circulation of the beverage. The removable freezable member may be a component of the fountain, such as a portion of the central support or one of the trays secured to the central support.
