Title: Method for extracting motion errors of a platform carrying a coherent imaging radar system from the raw radar data and device for executing the method
Inventor: MOREIRA JOAO
IPC: G01S13/90
Filed: 1990-07-06
Granted: 1995-01-31
Abstract: In a method for extracting motion errors of a platform carrying a coherent imaging radar system from raw radar data, azimuth spectra continuously following each other in time are formed over a set period of time for the imaging of terrains with mainly homogenous ground reflectivities.An estimate of the ground reflectivity part  is performed with a Kalman filter and with the aid of the azimuth spectra represented and system parameters entered.  Then the antenna pattern part    is obtained by dividing the azimuth spectrum by the estimated ground reflecti-vity part.      By frequency filtering a separation of the drift angle ? (t) from the velocity Vb(t) in the LOS-     direction of the antenna is subsequently performed and then the velocity obtained is subjected to normalization   after having been integrated, from which results the displacement in the line of sight direction of the antenna.

Title: Scalable compound instruction set machine architecture
Inventor: VASSILIADIS STAMATIS
IPC: G06F9/318
Filed: 1991-04-03
Granted: 2000-01-11
Abstract: Scalable compound instruction set machine and method which provides for processing a set of instructions or program to be executed by a computer to determine statically which instructions may be combined into compound instructions which are executed in parallel by a scalar machine. Such processing looks for classes of instructions that can be executed in parallel without data-dependent or hardware-dependent interlocks. Without regard to their original sequence the individual instructions are combined with one or more other individual instructions to form a compound instruction which eliminates interlocks. Control information is appended to identify information relevant to the execution of the compound instructions. The result is a stream of scalar instructions compounded or grouped together before instruction decode time so that they are already flagged and identified for selective simultaneous parallel execution by execution units. The compounding does not change the object code results and existing programs realize performance improvements while maintaining compatibility with previously implemented systems for which the original set of instructions was provided.

Abstract: The invention relates to a structure for positioning a cathode ray tube in a cabinet of a television receiver. The cabinet typically includes a front window opening and window frames which surround that opening. A portion of each window frame is formed so as to be elastically deformable outwardly due to contact between a cathode ray tube and the cabinet when assembling them together. Variation in a dimensional relationship between the cabinet and the cathode ray tube caused when positioning the cathode ray tube within the cabinet is compensated for by the elastic deformation of portions of the window frames. The window frames are an integral part of wall portions of the cabinet. Preferably each of the front window frames is gradually reduced in thickness from its proximal end portion in contact with a wall of the cabinet, towards its free end.

Abstract: This invention solves problems encountered in driving conveyor belts where mating belt drive engagement surfaces, sprocket drive surfaces, pivot rods and pivot rod surfaces all interact to cause wear and unreliablity in belt operation. Pivot rods are removably confined to prevent linear movement out of the belt due to conditions encountered in operation with corresponding interference or failure. Driving engagement is improved for variously shaped modular belt.links with drive surfaces extending from cylindrical structure about the pivot rod journalling aperture to form drive surfaces for mating with sprocket teeth. Dynamically moving sprocket drive surfaces interact between substantially radially disposed parallel drive planes on both the sprocket and the belt modules, thereby to avoid radially directed forces that drive the belt away from the drive sprocket to cause wear and unreliability. Trapezoidal shaped mating drive teeth upon the modules extend from a generally cylindrical body about the pivot rod. Sprocket drive teeth engage respective ones of such trapezoidal drive teeth on different end to end intercoupled modular links so that the belt may be driven in opposite directions. At the belt edge, one of two different pivot rod retention cap embodiments swivels elastically away from the normal pivot rod axis position retaining a pivot rod in place to permit pivot rods to be inserted or removed.

IPC: G07F9/00
Filed: 1991-12-30
Granted: 1996-08-27
Abstract: A coin processing apparatus arranged to automatically execute a cancellation process for canceling acceptance of an inserted coin by detecting, on the basis of output levels of receiving coils in a plurality of sets of coin selecting coils disposed on a coin path, a fact that the inserted coin has been guided into a return path through the operation of a return lever. and also to judge the occurrence of coin jamming and coin counter-flow on the basis of the output levels of the receiving coils. The output level of the receiving coil in each of the plurality of sets of coin selecting coils is monitored so as to carry out the automatic cancellation process in case the output levels of the respective receiving coils concurrently exceed a predetermined threshold level and persist longer than a predetermined period of time. In case the output level of the receiving coil in at least one of the plurality of sets of coin selecting coils exceeds the, predetermined threshold level and persists longer than a second predetermined period of time, it is judged that the coin jamming has occurred.  Further, in case the output level of the receiving coil of the most downstream one of the plurality of sets of coin selecting coils exceeds the predetermined threshold level and the detection output occurs again after the lapse of a third predetermined period of time from the time point when the detection output has once ceased, then the coin judged as a true coin is treated as a false coin.

Granted: 2004-11-16
Abstract: A novel conjugate vaccine comprising partially hydrolyzed, highly purified, capsular polysaccharide (Ps) from Streptococcus pneumoniae bacteria (pneumococci, Pn) linked to an immunogenic carrier protein, is produced by a new process. The conjugate is useful in the prevention of pneumococcal infections. Vaccines comprising a mixture of from one to ten different pneumococcal polysaccharide-immunogenic protein (Pn-Ps-PRO) conjugates induce broadly protective recipient immune responses against the cognate pathogens from which the polysaccharide components are derived. Young children and infants younger than 2 years old, normally unable to mount a protective immune response to the Pn-Ps alone, exhibit protective immune responses upon vaccination with these Pn-Ps-PRO conjugates.

Abstract: The present invention relates to a screw-shaped titanium anchoring member for permanent anchorage in bone tissue, specifically permanent anchorage of artificial teeth or tooth bridges in the jaw-bone. The tip of the anchoring member comprises at least one cavity (4). The edges of the cavities on the outer cylindrical surface form cutting edges (5) to provide self-tapping when the anchoring member is screwed into the bone tissue. The total volume of the cavities is adapted to contain the scraped-off bone tissue material, i.e. all the scraped-off bone tissue material can be housed in the screw in the volume formed by the cavities. Behind the cutting edges (5) the anchoring member has a clearance surface (9), i.e. behind each cutting edge the surface of the anchoring member is slightly bevelled towards the center of the anchoring member. By means of such clearance surface any squeezing effect which might occur in the cutting portion of the fixture when it is screwed into hard bone tissue can be avoided.
