Abstract: In a multiprocessor system including a plurality of cache units which are connected in common to a main storage (20) and to instruction processing units, respectively, each cache unit (3n) comprises a flag circuit (5n) divided into a plurality of flag bit areas (FA-1 to FA-M) which correspond to block areas (BA-1 to BA-M) of a cache memory (4n).  Each flag bit area memorizes a flag bit corresponding to a block memorized in the corresponding block area to indicate presence or absence of one of memory blocks in a common memory area of the main storage in correspondence to the memorized block.  Supplied with a cache clear request (CRn) from an n-th one (1n) of the instruction processing units, a cache clear circuit (6n) clears the cache memory so as to erase the memorized block when the flag bit indicates presence of the above-mentioned one of the memory blocks in the common memory area.  When a block fetching circuit (7n) stores a memory block fetched from the main storage in the cache memory, a fetch detecting circuit (8n) detects whether the fetched memory block is present or absent in the common memory area.  When the fetched memory block is present in the common memory area, a flag setting circuit (9n) sets the flag bit indicative of presence in the corresponding flag bit area.

Abstract: A percutaneous implant device includes a main body portion and a flange extending outwardly from the main body portion.  The flange has a free edge and can have a thickness that decreases as an imaginary point moves toward the free edge.  The stiffness of the flange decreases as an imaginary point proceeds from portions of the flange nearest the main body portion to portions of the flange nearest the free edge.  This is accomplished in one embodiment by a flange density that decreases as the imaginary point moves toward the free edge.  In another embodiment, the porosity of the flange can increase as the imaginary point moves toward the free edge.  The thickness and density of the flange can decrease while the porosity increases as the imaginary point moves toward the free edge.  The thickness and thread count of a textile flange can decrease as the imaginary point moves toward the free edge.  The thickness and packing density of a fibrous flange can decrease as the imaginary point moves toward the free edge.

Abstract: A speech coding system of the code excited linear prediction (CELP) type comprises means (24,26) for filtering digitised speech samples to form perceptually weighted speech samples.      Entries in a one-dimensional codebook (110) comprising frame length sequences are filtered in a perceptually weighted synthesis filter (28) to form a one-dimensional filtered codebook (38). The filtered codebook entries are compared with the perceptually weighted speech signals to obtain a codebook index which gives the minimum perceptually weighted error when the speech is resynthesised. Using a one-dimensional codebook (110) reduces the amount of computation which is required compared to using a two-dimensional codebook.

Abstract: ABSTRACT OF THE DISCLOSURE    A safety cover for an electric receptacle has a mounting plate fitting over an electrical receptacle, and a cover assembly with a cover edge extending around the periphery thereof, the mounting plate having an edge engagable surface thereon corresponding in shape to the cover edge.  The cover assembly is mountable on the mounting plate between a closed and an open position.  The cover assembly has a plurality of locking projections spaced around the periphery of the cover assembly at positions so that they are incapable of simulta-neous operation by a hand below a predetermined size.  When the cover assembly is closed, locking hooks on the locking projections engage in locking hook receiving apertures in the mounting plate structure and the cover edge is snugly abutted against the edge engagable surface.  The cover assembly can be moved to the open position only by simulta-neous deformation of the cover assembly at the positions of the locking hooks sufficient to move the locking hooks sufficiently far inwardly of the cover assembly to free the locking hooks from the locking hook receiving apertures.

Title: Feed network for a dual circular and dual linear polarization antenna
Inventor: BAINS PARAMJIT S
IPC: H04B7/155
Filed: 1991-04-12
Granted: 1995-10-03
Abstract: A feed network for an antenna system, e.g., a phased array antenna system, which is operatively associated with a signal source, e.g., satellite-based transponders, which generates first and second R.F. signals of circular polarization, and third and fourth R.F. signals of orthogonal linear polarizations. The feed network includes a 3dB hybrid coupler or the like for splitting each of the first and second R.F. signals into first and second signal components disposed in phase quadrature with each other. Facilities are provided for applying the first signal components of the first and second R.F. signals, and the third R.F. signal, to a first beam forming network (BFN); and, for separately applying the second signal components of the first and second R.F. signals, and the fourth R.F. signal, to a second BFN. Subsequent to their emergence from the BFN's, the first and second signal components of each of the first and second R.F. signals are applied to respective through and side ports of ortho-mode-tees (OMT's) which function to re-combine the first and second signal components, in phase quadrature, in order to thereby produce output first and second R.F. signals of opposite-sense (i.e., dual) circular polarizations. The third and fourth R.F. signals pass unaffected through the OMT's as output third and fourth R.F. signals of orthogonal (i.e., dual) linear polarizations. The first, second, third, and fourth output R.F. signals are then fed through common transmission lin?? to excite the individual antenna elements of the antenna system.      In an alternative embodiment, the feed network has an architecture which is virtually identical to that of the preferred embodiment described above, except that pin polarizers or the like are provided between the OMT's and the antenna elements. However, in the alternative embodiment, the first and second R.F. signals are of orthogonal linear polarizations, and the third and fourth R.F. signals are of opposite-sense circular polarizations. The first and second signal components of the first and second R.F. signals are re-combined at the OMT's to produce intermediate first and second R.F. signals of opposite-sense circular polarizations. The pin polarizers function to convert the intermediate first and second R.F. signals to orthogonally linearly polarized output first and second R.F. signals. The first, second, third, and fourth R.F. signals of both of the above-described embodiments preferably occupy different frequency bands.
