Abstract: The risk of loss in individual collateral loans may be evaluated by taking into consideration the market supply and demand for the collateral/asset, as well as the amount of the loan balance in proportion to the value of the collateral. A Collateral Risk Index is determined using information regarding the total number of sales of the collateral/asset, the total number of pending listings, the total number of active listings, and the total number of expired listings in a time period. This information is used in conjunction with the loan balance versus the collateral/asset value to determine an index reflective of the risk of loss to the lender or investor.

Abstract: A variable displacement peristaltic pump includes an stator carrying a flexible resilient tube, and a spoke-like array of pinch rollers for cooperation with the flexible tube. The rollers extend radially of the axis of a driven rotor, the stator and tube extending tangent to the axis of rotation of the rotor and being adjustable radially of the rotor axis, thus providing for adjustment and calibration of the pump output.

Abstract: A microprocessor-controlled interface for permitting any digital host computer to receive serial digital data from any instrument wherein (a) the time at which digital data from the instrument is to enter the host computer and (b) the logical structure of the digital data entering the host computer are controlled by instructions from the host computer to the microprocessor and wherein (a) physical formatting incompatabilities between the host computer and the instrument and (b) the communicating of prohibited characters from the instrument to the host computer and vice versa are avoided. The timing control and logical structure of the digital data are effected by directing data from the instrument into a scratchpad memory, which is divided into records pursuant to instructions from the host computer, the contents of the scratchpad memory being sent to the host computer upon a corresponding instruction therefrom. A terminal for communicating with the host computer and the instrument may be included.
