A three-dimensional image is derived from two-dimensional images. At least one of the two-dimensional images has a predetermined number of pixels. Depth measurements are derived from the two-dimensional images. The number of derived depth measurements is substantially equal to the predetermined number of pixels. The three-dimensional image is derived from the two-dimensional digital images and the depth measurements.

A first condition determining portion 6 determines whether or not a picture moves corresponding to inter-field variations of space variation amounts SG (t), SG (t-1), and SG (t+1). A second condition determining portion 7 determines whether a picture moves corresponding to inter-field differences FiGu (t-1), FiGu (t), FiGd (t-1), and FiGd (t). A third condition determining portion 8 determines whether or not a picture moves corresponding to a ratio gf of the inter-frame difference FrG to the spa...

A position determining system for determining a position of a rotor of a rotating motor has sensors that are coupled to the rotor. The sensors generate, in response to a rotation of the rotor, a quadrature signal that has sine and cosine components. The position determining system calculates a sum (A.sup.2) of a squared value of the sine component (A.sup.2sin.sup.2x) and a squared value of the cosine component (A.sup.2cos.sup.2x). An amplitude correction factor (A) is calculated as the squared r...

A determining device for determining a failure in an engine cylinder of an internal combustion engine, comprising a variation detecting unit for sequentially detecting a variation in an engine speed between a first engine speed detected by an engine speed detecting unit during a combustion process at a first engine cylinder and a second engine speed detected by the engine speed detecting unit during a combustion process at a second engine cylinder immediately preceding the first engine cylinder ...

In an extrusion process comprising the steps of fabricating a metal billet, heating said billet for a predetermined time and at a selected temperature to increase its plasticity and then forcing said heated billet through a small orifice to produce a desired extruded object, the improvement comprising the steps of randomly inserting a plurality of small metallic thermal tabs at different cross sectional depths in said billet as a part of said fabricating step, and examining said extruded object ...

An apparatus and method are provided for measuring hematocrit. A diluted blood sample is passed through a well-known conductivity sensor providing a sensor pulse for each sensed blood cell. Each pulse has a peak amplitude corresponding to the size of a blood cell passing through the sensor. During a first time period initiated by passing of the sensor pulse above a threshold level, the sensor pulse is coupled to peak detecting means, and a signal indicative of the level of the peak is generated ...

A method of determining the volume of gas in a well below the wellhead includes measuring the gas flow rate in the well annulus, closing the wellhead and measuring the change in pressure with time, and calculating the volume from the recorded data. A further method includes determining the change of pressure with time with the wellhead closed, venting the well through a calibrated orifice and measuring pressure changes with time for a short interval of time, and calculating from the recorded dat...

Apparatus for determining the internal stress within electrodeposited metals is disclosed. The apparatus includes an improved spiral contractometer wherein the spiral substrate is coupled directly to a dial indicator without the use of a gear system. A rod, passing between the dial indicator and the lower end of the spiral substrate, causes a dial indication for changes in the radius of curvature of the spiral substrate. To determine the internal stress that is created within metal electrodeposi...
