Patent EP-0351546-A2 (EP)
Inventor: PFLUGER ANTONIO DR
IPC: F24J2/04
Filed: 1989-06-14
Abstract: A solar collector for the generation of high temperatures including a tub-like housing defining a cavity, a glass plate for sealingly closing the cavity, a selective absorber and a trasparent thermal insulation structure located on the inside of the glass plate. An air gap separates the selective absorber from the glass plate. The solar collector is operated at a vacuum of less than 10000 pascal by means of a vacuum pump. The transparent thermal insulating member reduces the air convection and acts similarly to a mulitple pane for the reflected, diffuse thermal radiation. High efficiencies are thus achievable even at large temperature difference between the absorber and the area outside the solar collector. The thermal insulation effect of the air gap and at the same time of the microporous thermal insulation located in the bottom of the housing is varied by regulation of the degree of vacuum. A higher air pressure results in greater thermal losses of the absorber toward the thermal insulation member and the microporous insulation, whereby the temperature of the absorber is controllable.

Abstract: A method is disclosed for measuring the volume of a pile of material on a substrate. A pair of binocular stereo images of the material are captured and digitized. The images are filtered using a Laplacian of Gaussian filter function. The signs of the filtered images are cross-correlated at various relative alignments to generate a correlation response. The center of area of the correlation response is determined by calculating the displacement of the center of symmetry of two regions of constant gradient. The volume of the material (in cubic pixels) between a reference plane and the viewed surface of the material is obtained by multiplying the area of the correlation window by the displacement of the center of symmetry. The volume of the material in physical units is obtained by multiplying the volume in cubic pixels by parameters determined by the imaging geometry.

The main member (1) has a barrel (2), a head (3) fitted in an upper portion of the barrel (2), a discharge section provided at an upper end of the head (3), a passage cylinder (5) communicating with the discharge section and extended downwardly into the upper portion of the barrel (2), a cylindrical piston (6) formed at a lower end of the passage cylinder (5), and a resilient discharge valve (7) in the passage cylinder (5). The cylinder (8) is movably inserted into the barrel (2) to be elevationally movably engaged with an outer surface of the lower portion of the passage cylinder (5) and to be resiliently urged downwardly. The cylinder (8) has a suction valve (10) at its lower end thereof. The container body (12) is movably inserted into the barrel (2). The container (12) has a neck portion (12a) is tightly engaged with an outer surface of a lower portion of the cylinder (8). The container (12) has a slidable bottom plate (14). A lower end of the container body (12) is closed by a bottom cover (15). A hammer (16) is elevationally movably. inserted into a gap between the bottom cover (15) and the slidable bottom plate (14). When the container is strongly axially fluctuated, the hammer (16) hits the slidable bottom plate (14) to apply an impact to the slidable bottom plate (14). Thus, the slidable bottom plate (14) is intruded by the impact into the container body. The liquid in the container body is pressurized by the intrusion of the slidable bottom plate (14), air bubbles adhered to the ball valve body (9) of the suction valve are thus compressed and isolated from the ball valve body, again mixed within the liquid, and discharged together with the liquid through the discharge valve.

Abstract: A method using CH Loc  (change-local) type information is used for data prefetch (D-prefetch) decision making. This information is stored in history tables H, there being one such table for each CP at, for example, the buffer control element (BCE). For each line L, H[L] indicates the information for L in H. Two different types of histories may be kept at H:
     (1) XI-invalidates - At each H[L], there is recorded whether L was XI-invalidated without refetching.   (2) CH Loc  - At each H[L], there is also recorded local-change history, i.e., whether L was stored into since the last fetch.   
     It is also possible to keep a global H at the storage control element (SCE). In this case, the SCE maintains a table I recording, for each line L, information I[L] recording whether L involved XI-­invalidates during the last accesses by a CP. Upon a cache miss to L from a processor CP i , the SCE prefetches some of those lines that involved XI-­invalidates (indicated by I) into cache C i , if missing there. The management of table I is simple. When an XI-invalidate on L occurs, e.g., upon a store or an EX fetch, the corresponding entry is set. When L is accessed, e.g., upon D-fetch misses, without XI-invalidate, the entry in I is reset. Another criteria for turning an I entry OFF is when the line is fetched, e.g., on demand or upon prefetch.

Title: Mapping digital data sequences
Inventor: FORNEY DAVID G JR
IPC: H04L27/34
Filed: 1990-02-16
Abstract: In a so-called trellis shaping modulation system, instead of mapping a digital data sequence into a sequence of signal points drawn from a finite-dimensional signal point constellation as in typical coded modulation, the data sequence is mapped into a sequence of signal points drawn from a so-called trellis constellation of available infinite-dimensional sequences so that there is no single N-dimensional constellation used repeatedly in each N dimensions. The region occupied by the available sequences in sequence space is shaped to minimize the required power; i.e., preferably the region is an approximation to the Voronoi region of the trellis code (where the trellis code is not just a repeated lattice code).

Abstract: A laser oscillator/amplifier system in which thermally induced birefringence in the gain medium of the oscillator is compensated by thermally induced birefringence in the gain medium of the amplifier. The system produces a quality output beam efficiently and with high power density in the preferred polarization. The oscillator cavity (10) has a high reflector (12) at one end and an output coupler (13) at the second end with an oscillator gain medium (14) exhibiting thermally induced birefringence in between. An amplifier (11) exhibiting thermally induced birefringence which matches the thermally induced birefringence in the oscillator gain medium is mounted to receive the output of the oscillator cavity. A ninety degree rotator (21) is mounted between the oscillator gain medium (14) and the amplifier (11) so that thermally induced birefringence in the oscillator gain medium is compensated by the matching thermally induced birefringence in the amplifier. The ninety degree rotator may be mounted inside the oscillator cavity, that is, between the oscillator gain medium and the output coupler; or it may be mounted outside of the oscillator cavity, that is, between the output coupler and the amplifier, as shown.
