  • Publication number: 20050254913
    Abstract: A device for machining grooves (20) in a cylindrical bore emerging at the end of a master cylinder. The device includes a cylindrical tool (44) with a peripheral set of teeth (45) formed thereon by a series of cutting teeth (46). The tool (44) is inserted axially in the bore of the master cylinder (1) through a tool-holder shaft (39) that is initially driven in an orbital movement and later held immobile in rotation about its axis (42) and the master cylinder 1) and the tool-holder shaft (39) are thereafter separated from each other by axial translation.

  • Patent number: 6052673
    Abstract: Data processing for novel form of relationship management links, supervises, and balances depositors, marketing agents, financial intermediaries, mortgage brokers, and borrowers in an inflation-adjusted financing program. Funds are deposited in participating financial institutions in return for certificates of deposit yielding a fixed rate of interest, plus principal growth at a yearly rate equal to that year's rate of growth in the Consumer Price Index-All Urban Consumers, All Items. Funds on deposit are loaned to borrower, either directly or through brokers, at a rate calculated by adding three components: a fixed debt service rate, a fixed constant interest rate, and an inflation factor interest rate which reflects the effects of inflation on the outstanding loan balance.

  • Patent number: 5365934
    Abstract: An exercise apparatus for measuring heart rate is provided which comprises a sensor for generating a signal which includes the biopotential signal produced by a heart. This signal is filtered, amplified and digitized. A computer autocorrelates the digitized signal. A plurality of signal indication routines then scan the autocorrelated output for the presence of periodic signals. Each of the signal indication routines uses different search or filter criteria, such as peak and wave form detection, and generates one (and in some cases, several) candidate heart rates. An arbitrator then selects one of the candidate heart rates according to predetermined criteria. These criteria include the value of previously selected heart rates. In one embodiment, the signal indication and arbitration routines are especially well-suited for measuring the heart rate of a user while exercising on a stair climbing machine or treadmill.

  • Patent number: 5135447
    Abstract: A step type exercise apparatus is disclosed in which two pedal members are connected for reciprocating movement by a chain which, in turn, operates through a transmission providing a resistive force to the pedals. The resistive force is supplied by an alternator which is controlled by a computer. Means are provided to lubricate the chain thereby prolonging the life of the chain.
