Abstract: The disclosure is directed to a system and methods for dynamic diagnosis of musculoskeletal conditions. The methods include monitoring at least one body part of a subject with at least one sensor, the at least one sensor configured to detect motions of the at least one body part of the subject, the at least one sensor comprising a Micro Electro Mechanical System (MEMS) sensor. The at least one sensor transmits kinematic data to a signature-comparing device. The methods include obtaining composite signatures of the subject based on the kinematic data, the composite signatures comprising at least one motion signature. The methods also include comparing the composite signatures of the subject to a normal composite signature to determine whether a difference between the composite signatures of the subject and the normal composite signatures is larger than a pre-determined threshold.

Abstract: A system having a catheter having a distal pressure sensitive capacitive element providing an impedance and phase shift which varies responsive to the amount of pressure from blood external the catheter, a detector having electronics for determining the impedance and/or phase shift. This impedance and or phase shift corresponds to the pressure of the blood about the distal end of the catheter. When the catheter is inserted into a patient's body, the impedance or phase shift is detected quasi wirelessly without special signal communication means like optical fibers or electrical wires from outside the patient's body utilizing the patient as a ground path and the catheter shaft as an electrical conductor.

Abstract: A system for detection of blood pressure in a blood vessel includes a guide wire and a LC resonance circuit provided at a distal end of the guide wire. The resonance circuit may be a non-LC resonance circuit responsive to changes in pressure of fluid external to the guide wire such that the resonance circuit has a resonance frequency that varies in accordance with changes in pressure of the external fluid.

Abstract: A compliant interface (14,16) for vehicular seat weight sensors minimizes parasitic stresses affecting sensor output. In one embodiment, an integral compliant interface (14) has an annular flange (14a) attached to a post extending from the sensor body with a first compliant member (14r) disposed between the annular flange and an upper elongated flange (14h) of a mounting bracket (14l) and a second compliant member (14s) disposed between the annular plate and a lower elongated flange (14k) to allow pivotal movement of the sensor limited by a motion stop member (14f) of annular flange (14b) engaging the lower flange. An overload cage (14u) may be placed over the sensor and attached to an additional flange (14l) to contain the sensor in the event of a failure of the mount in a catastrophic high speed crash. According to another preferred embodiment, an interface having upper and lower body members are formed with a sensor post receiving bore (16c) for attachment to the post.
