摘要： In the disclosed computerized lending systems, terms of contracts are coordinated between a plurality of parties, each of which operate party client systems to interface to the electronic transaction processing system, including a database of transactions representing contracts, parties to the contracts and at least essential terms of the contracts. Signaling to each of the parties can be done without identifying each party to the other, including throughout execution of the contract. The logic to coordinate can be contract term negotiating logic and/or auction logic and the binding contract can be a loan contract, with the loans being obtained through an auction process directly between lender and borrower. A lender might have a standing order that can be filled with loans to multiple borrowers, to provide diversification. Contracts and loans can be represented by sponsors, wherein a sponsor might introduce a borrower to the system as well as be part of the process of default management for the borrowers that sponsor brings to the table. Reputations might be tracked and used in contract term negotiating, including reputations of borrowers and reputation of sponsors who sponsor borrowers. Reputation values of sponsors might relate to performance of loans of borrowers sponsored by those sponsors. Risk mitigation might occur by way of personal relationships between borrowers and sponsors.
摘要翻译：在所公开的计算机化贷款系统中，合约条款在多方之间进行协调，每个方面操作方客户端系统以与电子交易处理系统接口，包括代表合同的交易数据库，合约方，至少基本合同条款。可以在不确定每一方的情况下，包括在执行合同期间，向各方发出信号。协调的逻辑可以是合同期限谈判逻辑和/或拍卖逻辑，有约束力的合同可以是贷款合同，贷款通过直接在贷方和借款人之间的拍卖过程获得。贷款人可能会有一个可以向多个借款人提供贷款的常规订单，以提供多元化。合同和贷款可以由赞助者代表，其中赞助商可能会向系统介绍借款人，并将其作为赞助商借款人的违约管理过程的一部分。声誉可能在合同期限谈判中得到追踪和使用，包括借款人的声誉以及赞助借款人的赞助商的声誉。赞助商的声誉价值可能与由赞助商赞助的借款人的贷款履行有关。风险缓解可能通过借款人和发起人之间的个人关系来实现。

摘要： An audio processing system that includes an audio filter having one or more elements capable of having state, such as a capacitor, an inductor or a delay. A saturation detector is configured to detect saturation of the audio filter and to generate an output when saturation of the filter is detected, such as a switch control signal. A switch is connected to the audio filter and the saturation detector, wherein the state of one or more of the elements of the audio filter is changed when the saturation detector provides the output to the switch, such as when the switch shorts the element and causes the energy stored in the element to be dissipated.

摘要： A grounding switch is described which operates properly even in the presence of negative voltages on a signal line. The grounding switch uses isolated field effect transistors that have their substrates tied to different voltages. The isolated field effect transistor has a gate voltage and substrate voltage which can be pulled down to a negative voltage when the signal line has a negative voltage allowing the switch to remain open even with a negative voltage.

摘要： A circuit for providing a reference voltage can be widely used in audio applications. However, at startup an abrupt start in the reference signal can cause undesirable audible artifacts. A circuit employing feedback of a reference voltage to control the charging of a capacitor which provides the reference voltage can be used to provide a smooth startup to the reference voltage. The circuit contains a differential pair for steering a fixed current source from one path to another as the reference voltage increases. The steered current can then be mirrored into one or more current mirrors where the newly mirrored current can be squeezed to zero when the difference between a desired reference voltage and the reference voltage approaches zero. This newly mirrored current can be used to charge a capacitor which is used to provide the reference voltage.

摘要： High linearity is essential in audio circuitry. As sampling rates for audio applications are needed, high speed and high linearity are needed in analog and mixed signal portions of audio circuitry such as in current mirrors. A current mirror employs two current paths in an output. The first current path is driven by a fast acting transistor through a resistor. The second current path is driven by a differential amplifier coupled to another transistor through another resistor. The second current path is used to maintain linearity by causing the voltage across both transistors to be the same.
