Abstract: A system and method for auditing medical records to determine the coding accuracy of medical coding professionals. The system assigns an expected coding accuracy level to each medical coding professional, establishes a confidence level and a margin of error for each expected coding accuracy level, determines code populations for each medical coding professional, determines a sample size for each medical coding professional for each code population, randomly retrieves medical records to obtain, for audit, samples of codes assigned by the respective medical coding professionals, determines if the codes obtained from the retrieved medical records were assigned correctly, and calculates an accuracy for each medical coding professional based on the number of correct code assignments by each respective medical coding professional.

Abstract: A coupling device of synchronous cable for connecting a frequency of an induced voltage generated from a fly back transformer (FBT) is provided. The coupling device includes a metal support 53 formed with an accommodating groove 52 so as to be interposed with a shield metal 51 to a front wall surface of a case 50 of the FBT. Case 50 is provided with a ferrite core 60, and the ferrite core 60 is inserted and supported between the metal support 53. Shield metal 51 of the metal support 53 is connected with a synchronous cable 70 and grounded so as to draw out an induced voltage of the FBT. According to this design, not only a frequency of the induced voltage generated from the FBT is made to be stably drawn out, but also the coupling of the synchronous cable is automated whereby its workability and a productivity are improved.

Abstract: Thermoplastic elastomers in which low molecular weight ethylene/propylene/nonconjugated diene rubber ("liquid" EPDM rubber) replaces part of the high molecular weight EPDM rubber used in conventional blends exhibit better tension set properties than conventional blends in which liquid EPDM rubber is not used. A masterbatch containing liquid EPDM rubber and phenolic curing resin which is added to a mixture of polyolefin, high molecular weight EPDM rubber, and other ingredients during mixing results in a thermoplastic elastomer having better mechanical properties as well as better tension set properties than blends of conventional materials.

Abstract: Disclosed is a keyboard device of an electronic keyboard instrument generating a sound upon actuation of a switch disposed on a main plate by a pushing operation of a keyboard; the device includes a touch element varying in position according to the operation of the keyboard and a guide element for guiding the touch element, so that pushing force of the keyboard may be regulated. Therefore, this device enables a player to feel the same sense of touch as that in a common piano by eliminating a sense of friction which may be exerted upon his finger when pushing down the keyboard.

Abstract: A combination folding ladder and height adjustable scaffold, comprises (a) a first assembly including a first leg and a second leg, each formed by an outer and inner telescoping member, and outer and inner rungs which connect the outer and inner telescoping members in substantially parallel, spaced apart relation; (b) a second assembly including a third leg and a fourth leg, each formed by an outer and inner telescoping member, and outer and inner rungs which connect the outer and inner telescoping legs of the third and fourth legs in substantially parallel, spaced apart relation; (c) positioning joints removably secured to upper ends of the for pivotally securing the first and second assemblies together; (d) a height adjustment assembly for varying the heights of the legs; and (e) a scaffold platform for use with the combination when the positioning joints are removed from the legs and the first and second assemblies are separated, the scaffold platform including a flat rectangular board, U-shaped supports a
