  • Publication number: 20130122466
    Abstract: The device performs reference point indentation without a reference probe. The indentation distance is measured relative to the instrument which remains substantially stationary during the impact process, which occurs on the order of one millisecond. In one embodiment, an impact motion with a peak force of order 28N creates an indentation in bone with a depth of approximately 150 ?m during which the instrument case moves less than 1 ?m. Thus the error in measuring indentation depth due to the motion of the case is less than 1%, making a reference probe unnecessary. Further, this “error” is consistent and can be corrected. In one embodiment, the device measures the fracture resistance of hard tissues by actually creating microscopic fractures in the hard tissues in a measured way. It creates these microscopic fractures by impacting the sample with a sharpened probe. The indentation distance in the sample is correlated with fracture resistance.

An embodiment includes a rotational stimuli applied to the rotational motion for testing that includes two separate components, a bias component and a probe component. The bias component for rotational motion is designed to temporarily turn off vestibular responses in one ear while the responsiveness in the opposite ear is simultaneously evaluated using the probe component of the stimulus. Responses from application of these stimuli are analyzed by isolating and separating the bias response from the probe response. The bias and probe component responses are parameterized by applying curve fits of mathematical functions to the isolated bias and probe component responses. These parameters characterize the patient's vestibular function.

  • Patent number: 7399281
    Abstract: A pain measurement system is capable of accurately and reliably measuring the magnitude of temporary pain in a patient while reducing burdens on the patient during pain measurement. The pain measurement system has a system assembly including a controller that controls an electric stimulus signal output unit to apply a pulse current which increases with time through an electrode. The value of the pulse current is recognized as a minimum sensed current value when a first signal is received. The electric stimulus signal output unit is then controlled to apply, through the electrode, a pulse current having a current value which increases from a predetermined initial value stepwise by nX (where X represents the minimum sensed current value and n represents a positive rational number). The current value of the pulse current is recognized as a pain-commensurate current value when a second signal is received.
