Title: Coding method of image information
Inventor: ONO FUMITAKA
IPC: H04N1/41
Filed: 1990-01-30
Granted: 1995-04-25
Abstract: A coding method of a binary Markov information source comprises the steps of providing a range on a number line from 0 to 1 which corresponds to an output symbol sequence from the information source, and performing data compression by binary expressing the position information on the number line corresponding to the output symbol sequence.  The present method further includes the steps of providing a normalization number line to keep a desired calculation accuracy by expanding a range of the number line which includes a mapping range, by means of a multiple of a power of 2, when the mapping range becomes below 0.5 of the range of the number line; allocating a predetermined mapping range on the normalization number line for less probable symbols LPS proportional to its normal occurrence probability; allocating the remaining mapping range on the normalization number line for more probable symbols MPS; and reassigning the predetermined mapping range to the remaining mapping range the half of a portion where the allocated remaining range is less than 0.5, when the allocated remaining range becomes below 0.5.

Title: Method and apparatus for descrambling a television signal
Inventor: WHITE CHARLES M
IPC: H04N7/171
Filed: 1990-03-19
Granted: 1995-06-13
Abstract: A baseband television signal having a video portion with a suppressed horizontal sync pulse is descrambled by using a variable attenuator.  The attenuator shifts the level of predetermined portions of the signal to restore the suppressed horizontal sync pulse to a normal unsuppressed level with respect to the rest of the signal.  A reference voltage is derived from a blanking level potential and sync level potential of the signal, and is equal to the zero carrier level of the video portion of the signal.  The reference voltage is utilized to maintain the level of the restored sync pulse at a proper value.
Patent CA-2016222-C (CA)
Inventor: OVERFIELD ROBERT EDWARD
IPC: G01N30/86
Filed: 1990-05-07
Granted: 2001-02-20
Abstract: A sample of a hydrocarbon oil containing asphaltenes is chromatographically analyzed by forming a mixture of the oil with a weak solvent. The mixture is passed in contact with a column of a stationary phase of fine solid particles of fully functionalized material, followed by a weak solvent. The solvent, after recovery from, the column, is analyzed for aromatics by UV-absorption of UV radiation in the range 200 to 400 nm. The absorbance of the UV light by the irradiated eluents across the UV wavelength range is monitored and the integral of absorbance is derived as a function of photon energy across the wavelength range. The magnitude of the derived integral in at least one time interval corresponding with aromatics in the eluent from the stationary phase is measured as an indication of the level of aromatics in the oil sample.      The weak solvent may be followed by a strong solvent which, in turn, may be followed by a strong solvent which is modified by the addition of a hydrogen bonding solvent. The solvents are analyzed for saturates, aromatics, polar compounds and any asphaltenic materials by the combination of the UV-absorption measurement and a mass sensitive measurement which measures the combined level of the saturates, aromatics, polars and any asphaltenic compounds present. Equipment to perform the foregoing analysis is also described. The analysis can be used for evaluation of are oil and/or for on-line regulation of an oil refining process.

Title: Viterbi decoder
Inventor: HATAKEYAMA IZUMI
IPC: H03M13/41
Filed: 1990-06-15
Granted: 2000-02-22
Abstract: ABSTRACT OF THE DISCLOSURE This invention relates to a Viterbi decoder for decoding a convolution coded reception signal. The Viterbi decoding is an algorithm for efficiently executing the maximum likelihood decoding using a convolution code by selecting a path locating at the minimum distance from a reception series between two paths which are joined.  Since it is necessary to store a state metric of each state, after the state metric of the surviving path was calculated by ACS calculation, it is considered to normalize metrics. However, this results in a large circuit scale and a low processing speed.  Therefore, in this invention, a maximum likelihood value of a present state metric is detected from a maximum likelihood branch metric pair before the ACS calculation and the preceding maximum likelihood state metric pair and metrics are normalized by using the maximum likelihood value.

Title: Self adjusting soft neck support collar
Inventor: SARKOZI JEFF
IPC: A61F5/055
Filed: 1990-09-14
Granted: 1994-05-31
Abstract: A soft neck support collar is disclosed comprising two offset and attached,  tubular ring elements,  each element hooking together at their respective ends.  Both ring elements contain a soft fill material such as nylon, cotton, polyester, acrylics, foam, foam chips, etc.  The combined effect of the fill material together with the tubular configuration, enables the neck to adjust for lateral forward and backward forces during movement.  The upper ring element is tapered at each end, so that when these ends are joined together, a space is formed into which the chin can fit, thereby maintaining the neck in a neutral position, and preventing hyperextension.          The lower ring element is hooked together at each end, and the rings are offset to enable the lower ring to close at the back of the neck, approximately opposite from the closure of the upper ring element.  Hence, the lower ring element functions as a continuous, uniform, tubular-shaped ring which does not interfere with movement of the chin.   Thus, in the closed configuration,  the neck support collar allows for neutral positioning of the chin and neck, and restricts neck mobility.

Abstract: A piezoelectric gas lighter has an actuator cap which is mounted on an upper part of a lighter body to be movable up and down between upper and lower positions relative to the lighter body and is urged to the upper position. The actuator cap is depressed toward the lower position to discharge fuel gas stored in a reservoir provided in the lighter body and to actuate an ignition mechanism to ignite the fuel gas.  A safety device for the piezoelectric gas lighter includes a projection which is provided on said upper part of the lighter body, a stopper member which is mounted on said actuator cap so that it can be movable relative to the actuator cap along a linear path between a locking position where a part of the stopper member is aligned with the projection and interferes with the projection to prevent downward movement of the actuator cap and a releasing position where said part of the stopper member is out of alignment with said projection and permits downward movement of the actuator cap and so that the actuator cap can be depressed by pushing downward the stopper member, and a spring which urges the stopper member to the locking position.  The projection has a vertical surface which extends downward facing toward the releasing position of the stopper member and the vertical surface holds the stopper member in the releasing position when the actuator cap is below said upper position.

Abstract: A fastener and a workpiece assembly comprises a fastener composed of a relatively strong, inflexible material having a shank. Wings are disposed on the shank, and the workpiece has portions thereof composed of a relatively flexible, resilient material. An aperture having a diameter is located through the portions. The wings define an outer diameter substantially greater than the diameter of the aperture. The wings are capable of swaging the apertures, thereby increasing the diameters thereof, to allow for passage of the wings. The relatively flexible, resilient material has sufficient elastic memory so that the diameter of the aperture will become smaller than the outer diameter defined by the wings after being swaged by the passage of the wings.
