Title: Method and apparatus for determining a quantizing factor for multi-generation data compression/decompression processes
Inventor: WATNEY JOHN
IPC: H04N19/00
Filed: 1992-03-25
Abstract: ABSTRACT OF THE DISCLOSURE           The invention provides techniques for changing the quantization used in multiple generations of data quantization such that the errors incurred in subsequent generations are substantially the same as the error incurred in the first generation even though the complexity of the data has been changed. To this end, in a preferred embodiment, quantizing factors are selected from a preselected finite non-degenerative set of quantizing factors provided in the form of arrays of a periodic series of individual quantizer values, wherein a special numerical relationship is maintained between corresponding quantizer values in successive arrays. A different quantizing factor may be selected for each generation of compression/decompression as required by changing data complexity as when performing a layering process during the generations. In another embodiment, an over-quantizing factor is chosen large enough to compress the data to a greater extent than that required in the first generation, such that sufficient compression still is provided in subsequent generations even though the same quantizing factor is used while the complexity of the data is being changed. If for some reason the complexity of the data changes faster than expected, it is necessary to change the quantizing factor to fit the data into the allotted space. To moderate the associated increase in noise, the invention technique includes a dither rounding process wherein a psuedo random number sequence in the range of 0...1.0 is selectively added as determined by a threshold. The invention also includes estimating a quantizing factor applied in a previous generation of image recording if this information is not available explicitly, by distinguishing the peaks and/or valleys of a histogram. The amplitudes of the peaks and/or valleys represent the number of counts of the respective values of frequency coefficients to be quantized.

Abstract: ABSTRACT     A description is given of a clutch with an input shaft (2), an output shaft (3) and gears (4 to 9, 13 to 16) mounted in pairs. The shaft (2, 3) or an inner race with cams (43) mounted on the shaft and rotating with the shaft is equipped with gripping surfaces (17) along its circumference. Rollers (10) are fitted between the gripping surfaces (17) and the inner surfaces (18) of the gears (8, 9, 13 to 16). Cams (20), mounted on an outer race (21) protrude into the spaces between the rollers (10). The outer race (21) is dragged by the first springs (35) from the corresponding shaft (2, 3) to an initial relative position and can be shifted against the force of the above-mentioned springs (35) with the help of a sliding element (39 or 44) to a secondrelative position. Sliding elements, fitted on a clutch-gear sleeve (37) produce the shift. The clutch-gear sleeve (37) is axially rotatable and is fitted over a synhronizer drum (27, 27', 27") on the shaft (2, 3). When the outer race (21) is shifted from the first to the second relative position, a frictional coupling (shifting position) results between the gripping surfaces (17) and the inner surface (18) of the corresponding gear.

Title: Molded protective exterior weather-resistant building panels and method of making and installing
Inventor: KEMERER W JAMES
IPC: E04C2/20
Filed: 1992-04-16
Abstract: ABSTRACT        Molded exterior building panels formed from thermoplastic material and method of making and installing such panels in aligned relationship on  building structures.  An upper margin of a building panel includes  nail slots for fastening to a building.  An upwardly projecting lip along the top defines an engageable mounting groove behind this lip. horizontally extending mounting hook on the back of a lower margin of each panel provides for hooking engagement with lip and groove of a next lower installed panel.  During installation such hooking engagement advantageously supports the weight of a panel being installed and automatically provides alignment of the panel with the next lower installed panel, thereby freeing an installer from the burden of holding a panel in a desired position at a desired level while driving nails through the nail slots.  Panels are molded from thermoplastic material with surface textures and patterns for simulating courses of attractive building surfacing products, such as clapboards, shingles, shakes and slates.  Front and back lap-joint channels are routed along panel ends.  The mounting hook is formed by heating, bending down and then setting a rear edge of a horizontally-extending, rearwardly-projecting ledge strip.          Elongated nail slots accommodate thermal expansion and contraction of installed panels.  Anti-overdrive ridges above and below the nail slots prevent driving nails so tightly as to restrict expansion and contraction.  Wider multi-course panels may have a second horizontally-extending, intermediately-located mounting hook on the back for engaging a locking strip.

Title: Hpth (1-37) fragment, its production, drug containing it and its use
Inventor: FORSSMANN WOLF-GEORG
IPC: G01N33/74
Filed: 1990-10-25
Abstract: A human blood peptide, hPTH (1-37), the structure of which has been elucidated, can be used as a drug for diagnostic, medical and industrial purposes. The isolation of an hPTH (38-84) fragment demonstrates the existence of the hPTH (1-37). Removal of amino-terminal amino acids on the hPTH (1-37) reduces its biological activity. The hPTH (1-37) which circulates in the blood is identical to the synthetic reference substance hPTH (1-37), but not fragments such as hPTH (1-33), hPTH (1-34) or hPTH (1-38). The existence of the hPTH (1-37) molecular form was proved by mass spectroscopy (plasma desorption method). A different biological activity and differences in the three-dimensional peptide structure between the hPTH (1-37) fragment and other hPTH fragments prove that this hPTH fragment is the preferred natural peptide of the parathormone family, which should be used for treating diseases of the parathyroids, the circulatory and respiratory systems, the male genital organ and the kidneys.

Title: Three axis thruster modulation
Inventor: YOCUM JOHN F
IPC: B64G1/26
Filed: 1992-08-26
Abstract: The three axes thruster modulation (8) of the present invention accepts three axes of input torque commands or angular acceleration commands and generates thruster selection and thruster timing (40) information which is used to fire thrusters (48) for the purpose of spacecraft attitude control and velocity change maneuvers. The modulation logic (8) works in all three axes simultaneously and is suitable for use with an arbitrary thruster configuration,including a configuration in which individual thrusters or thruster groups do not produce torques about mutually orthogonal axes. After thruster selection and on-times have been determined, the modulation logic (8) uses this information to compute a best estimate of the actual rate change (42) which is then compared to the commanded rate change (44) to develop a residual unfired rate change. The residual unfired rate change is retained and fed forward for addition to the subsequent acceleration command in computing the commanded rate change for the subsequent sample period (10, 20, 30). As a result, all commanded rate changes will ultimately be fired even if the commanded rate change is below a minimum rate change achievable.

Abstract: VAPOR SUPPRESSING FUEL    HANDLING SYSTEM            Abstract of the Disclosure A fuel handling system incorporates a reservoir canister within the fuel tank that is enclosed, but for a float controlled vapor vent valve with a vent orifice of predetermined size.  A second stage pump sends fuel to the engine, with unused fuel being returned to the canister through a bubble separator that removes the entrained fuel vapor bubbles and sends them into a vapor space just below the top of the canister.  A first stage pump continually runs to send fuel into the canister, thereby maintaining the vapor space at a vapor suppressing elevated pressure. When the vapor space grows far enough that the float falls and opens the vapor space, fuel sent in by the first stage pump and vapor is expelled.  The orifice is large enough to allow the vapor to be expelled, but small enough, relative to the first stage pump's capacity, that a vapor suppressing pressure is substantially maintained.
