This invention is a system that tracks the 3-dimensional position and orientation of one or more bodies (20) in a volume by a light based as well as at least one non-light based mensuration sub-system. This overcomes the limitation of light based mensuration systems to the necessity of the bodies (20) to be in constant line-of-sight of its light based position sensors (26). The invention possesses most of the accuracy and stability of its light based position measurement sub-system (24, 26, 72), but can also work without direct line of sight either for short periods of time or within certain parts of the volume. It does so by incorporating other sensors (31, 34), such as inertial or magnetic, which are frequently recalibrated against the light based sub-system (24, 26, 72) while the bodies (20) are visible by the light based sub-system (24, 26, 72).

A process is provided for determining the distance between two devices by sending ranging packets between them. The local device sends a first ranging packet, which the remote device sends holds for a first hold time before sending a second ranging packet in return. The local device also sends a third ranging packet, which the remote device sends holds for a second hold time before sending a fourth ranging packet in return. If the second hold time is twice the first hold time, then the propagation time for signals between the two devices can be determined solely by time measurements made by the local device. For received signals, these time measurements can be adjusted to provide accurate time estimates for a direct line of sight signal, which corresponds to a shortest transmission distance between the two devices. The propagation time can then be used to determine distance between the devices.

A biodynamic apparatus to perform correct, safe and effective SIT-UP and LEGS-UP exercises and simultaneously perform spinal arching, spinal decompression, and flexibility exercises, comprising of two part frame hinged at one end and a set of parallel bars that elevate and anchor the legs of the user concentrating the exercise in the abdominal area of the body. The main feature of the apparatus is provided by a device the inventor calls “flexor”. The flexor is not an ordinary lumbar support. Its function is to meet the natural fulcrum of the human torso, which is below the sacrum, to safely and efficiently articulate. Most exerciser bend the spine during the exercise, rather than the pelvis putting a tremendous negative stress on the vertebra and on the intervertebral discs. With the help of the “Flexor” the torso can move from horizontal to at least 90 degrees angle as one straight piece, free from the gravitational stress produced on the spine, especially on the cervical vertebra, by the weight of the head during the initiation of the exercises. It is a fact that ordinary SIT-UP and LEGS-UP exercises the work is performed for the most part by the neck, back and lumbar muscles during the first part of the movement placing a dangerous negative stress on the spine, and especially on the spinal cord. With the use of this apparatus, the reverse can be observed. The user by lying on the “flexor” places in traction the entire set of abdominal, pectoral and neck muscles creating a direct line of force between the abdomen and the head. The spine is arched and decompressed, the abdominal muscles are in traction and the lumbar muscles are neutralized since there are bent beyond their working point. This position of the body allows to safely concentrate 100% the force on the abdominal muscles to initiate the primary work constituted by the lifting of head of the user, instead of the neck, and on the lumbar muscles of the user, as well as to protect the spine and the weak abdominal muscles from negative stress and subsequent short and long term injuries. Decompression, arching, and flexibility of the spine, being achieved during this new method of performing SIT-UP and LEGS-UP exercises, simultaneously, make this apparatus bio-dynamically correct, as far as distribution, compensation and equalization of stresses; meet the scientific principles of muscle dynamics of traction and contraction; protect the spine from negative stress, especially the weak cervical and lumbar areas; maintain and enhance the spine's integrity and flexibility; and obtain maximum abdominal muscle developments, which are the major benefits of this invention. The flexor is mounted on two external parallel railing as to adjust to the length of all users. It also has an internal adjustable mechanism that allows its two padded flanges to adjust in width to accommodate all waist sizes of users for additional support and prevention of lateral stress to the lower spine.

A section of a wire rope is magnetized by longitudinally spaced magnetic poles. A magnetic field parameter, e.g. magnetic flux density, is measured in, by at least, one pair of points between the poles of magnetizing device (in an inter-pole area) at the object under test surface. The pair of points is formed by two sensors placed in the inter-pole area along a direct line parallel to the rope axis. The rope cross sectional area corresponds to a sum of the sensor pair signals. Local flaws, such as broken wires and pitting corrosion in the rope, is detected by a first differences of signals of the sensor pair. At least one additional magneto-sensitive sensor is located radially inward of the poles and weight coefficient A depending on a nominal value of the rope cross sectional area is subtracted from the sum of signals of the sensor pair thereby providing a second difference of the signals corresponding to the rope cross sectional area. The coefficient A value is chosen to get the minimum value of the second signal difference while the magnetizing device and all the sensors are placed onto the rope having a nominal value of a cross sectional area. A sensor unit in the inter-pole area includes a magnetic core in form of three longitudinally spaced ferrous elements. Pairs of the sensors are located in the gaps along a direct line parallel to the rope. Two embodiments of the magnetic heads are disclosed: the hollow cylinder-shaped one and the U-shaped one.
