Abstract: Systems and methods for document analysis. An image containing at least one document is received at a pre-processing stage and the image is analyzed for image quality. If the image quality is insufficient for further processing, this is adjusted until the image is suitable for further processing. After the image quality adjustment, the image is then passed to an initial processing stage. At the initial processing stage, the boundaries of one or more documents within the image are determined. In addition, the orientation of the image may be adjusted and the type of document(s) within the image is determined. From the initial processing stage, the adjusted image is then passed to a data extraction stage. At this stage, clusters of data within the document are determined and bounding boxes are placed around the clusters. Data regarding each of the clusters of data is then gathered.

Abstract: A beam 14 having, at one end, a tie-point 11 screwed to reference location 12 of vibrating panel 15. At the other end of beam 14 is rubbing-point 13. Rubbing-point 13 is pushed into contact with panel 15 at contact location 17 by the flexibility of beam 14. Direct rubbing occurs between 13 and 17 during vibration. But a friction linkage 18 (FIG. 1B) can be mounted between beam point 13 and panel location 17 to redirect rubbing direction and/or to amplify friction movement. Vibration of panel 15 will cause slippage (rubbing) between point 13 and location 17, therefore creating friction dissipation of vibration energy. Construction of beam 14 can be complex to include more rubbing-points (FIG. 2, 3, 4) or more rubbing pieces (FIG. 1A, 1C) that can rub with each other to create more friction dissipation.

Abstract: A programmable logic device (PLD) includes a central processing unit (CPU) and a programmable interface coupled to the CPU, wherein the programmable interface includes a core designated by a user. The programmable interface core allows devices, both on and off-chip, to communicate with the CPU. In one embodiment, the programmable interface core includes a crosspoint switch for coupling a plurality of devices and the CPU. Re-programmability of the PLD provides significant flexibility in providing features that can be parameterized based on the user's needs and/or associated design. Specifically, these parameterized features can be implemented in programmable resources on the PLD, thereby allowing these features to be modified at any time. Moreover, only those resources actually needed for the programmable interface core need be implemented, thereby allowing the user to optimize use of the remainder of the PLD.

Abstract: An apparatus (Z) having controllable impedance is inserted from output (22) to ground (23) of an audio-signal amplifier (20). Typically, the apparatus comprises a switch-chain (50) having multiple switches (52, 53, and so on); the first switch (52) is connected to one terminal (62) of the apparatus. A capacitor (82, 84, and so on) is connected from each switch to a second terminal (61). The network formed by the switch-chain (50) and the capacitor network (80) is called a matrix (60C). To bypass audio frequencies away from the chopping effect of the switches, an inductor (31) parallels the matrix. To prevent shorting of audio signals to ground, a larger capacitor (30) is in series with the inductor. An unstable voltage at output will see increasing capacitance as more switches are closed. The changing of capacitive impedance in relation to the amplitude of the unstable voltage is designed such that the unstable voltage cannot grow too large. More complex matrices further reduce voltage fluctuations.

Abstract: The invention relates to an absorption system having a regenerator (17) wherein an absorption process of the absorption of low-pressure ammonia vapor into a weak liquid solution of ammonia-water is carried out in the shell (16) of the regenerator (17) with the heat of absorption being used in a generation process wherein a high-pressure ammonia water solution is boiled in a conduit (14) passing through the regenerator (17). A waste heat recovery conduit (40, 40', 40") is provided for concurrent flow of an ammonia-water solution and ammonia-water vapor, the flow being heated (46) to boil the solution. The heated vapor is then introduced into the absorption process in the shell (16) of the regenerator (17) with the heat (46) used to boil the solution in the waste heat recovery conduit (40) being recuperated in the regenerator as the hot vapor is absorbed into the ammonia-water solution therein.

Abstract: An improved regenerative absorption cycle using a super-pressure boiler to achieve a high coefficient of performance (COP). In the basic cycle, an ammonia/water solution is boiled in high-pressure boiling conduit (66). Boiled-off high-pressure ammonia vapor is condensed (96), expanded to low-pressure (99), and boiled in evaporator (101) to extract heat from a refrigerating fluid going to cooling load (104). Low-pressure ammonia vapor from evaporator (101) returns to regenerator (28) and is absorbed back into low-pressure liquid. The low-pressure solution from regenerator (32) is then cooled in absorber (56) to reject heat from the cycle, and is then pumped (58) back to the high-pressure boiling conduit (66). In the present invention, the liquid solution from high-pressure boiling conduit (66) is pumped up to an externally-heated super-pressure boiler (11).

Abstract: An improved regenerative absorption refrigeration cycle having a high COP and a commercially practicable pumping system. In the basic cycle, an ammonia/water solution is boiled in an externally-heated generator (11). The boiled-off ammonia vapor is cooled (14) in a regenerator (16), condensed (28), expanded to low pressure (32), and boiled in an evaporator (34) to extract heat from fluid circulating to and from a cooling load (41). The low-pressure liquid ammonia returns (46) to the regenerator (16) and is absorbed back into the low-pressure water from the generator. The solution is then cooled in a low-pressure absorber (50), pumped (53) to a high-pressure conduit (57) which is heated by the regenerator heat before going back to the generator 11. The improved cycle uses at least one intermediate absorber stage 60 to absorb more ammonia vapor (69, 71) into the solution coming from the lower pressure absorber (50) to produce a cooled solution of higher ammonia concentration.

Abstract: Multi-effect regenerative absorption cycles which provide a high coefficient of performance (COP) at relatively high input temperatures. An absorber-coupled double-effect regenerative cycle (ADR cycle) (10) is provided having a single-effect absorption cycle (SEA cycle) (11) as a topping subcycle and a single-effect regenerative absorption cycle (1R cycle) (12) as a bottoming subcycle. The SEA cycle (11) includes a boiler (13), a condenser (21), an expansion device (28), an evaporator (31), and an absorber (40), all operatively connected together. The 1R cycle (12) includes a multistage boiler (48), a multi-stage resorber (51), a multisection regenerator (49) and also uses the condenser (21), expansion device (28) and evaporator (31) of the SEA topping subcycle (11), all operatively connected together. External heat is applied to the SEA boiler (13) for operation up to about 500 degrees F.
