Abstract: A fast disassembling joint structure includes a base part and a removable part. One end of the removable part is secured to a desired structure; the other end is a connection arm. The housing has a raceway and a first semi-circular concavity. The movable clamp has an insertion section to engage a recess of the connection arm. The insertion section has a second semi-circular concavity to fit with the first semi-circular concavity so as to pivotally connect with the connection arm. A spring is adapted to provide a push force for the movable clamp. A top cover, secured on the housing, is employed to house the spring and movable clamp inside. A handle of the movable clamp extends out of an opening of the cover so that users can manually control the handle to disassemble the removable part.

Abstract: In one embodiment of the invention, a programmable logic block within a programmable logic device includes: a plurality of lookup tables, each lookup table providing a combinatorial output signal; and a plurality of registers, each register being adapted to register a selected one of the combinatorial output signals, wherein the number of registers is less than the number of lookup tables.

Abstract: A device and method for cleaning fans in range or stove hoods by spraying steam onto the fan impeller area on which soot and cooking fumes condense to clean the impeller and wash the accumulated condensates down a drain. By using steam above atmospheric pressure as the cleaning fluid, the device uses significantly less water that other devices that spray water or an aqueous solution to clean the fan blades.

Abstract: A razor having a base, a ceramic blade installed in the base, a plurality of ceramic rollers installed in the base at two sides of the ceramic blade. The base has a lid having a slit allowing an edge of the blade to extend through and a plurality of openings allowing portions of the rollers to extend through. The rollers are supported by at least one resilient member such that the exposed portions of the rollers can be pressed inwardly for shaving and retrieved to the original height when the pressing force is relieved.

Abstract: A memory provides a programmable write port data width and an independently programmable read port data width. The independence between the programmable write port data width and the programmable read port data width is achieved without the use of a third clock domain.

Abstract: A programmable device with logic blocks is configured to cascade product terms from one logic block to another to increase the logical input width of the product terms. Each logic block may produce a plurality of product terms based upon the selection of inputs from a routing structure. Logic blocks configured to receive cascaded product terms includes a plurality of AND gates corresponding to the plurality of product terms.

Abstract: A programmable device includes a plurality of programmable blocks each associated with a distributed memory block. The programmable blocks may be configured as logic or memory. The addressing circuitry for each distributed memory block may be shared with its associated programmable block or may be separate.

Abstract: Cascadable logic block architectures are disclosed for programmable logic devices, such as for high density and high performance complex programmable logic devices. The logic block architectures provide, for example, clusters or groups of logic blocks that may have cascadable inputs and/or product terms to provide flexible logic width and/or depth capability. The logic block architecture may, for example, be implemented in conjunction with a multi-stage interconnect architecture to provide array fuse density and/or interconnect fuse density savings compared to conventional architectures.

Abstract: The fuse points within a programmable AND array may be programmed with configuration signals to select for logical signals to form product term outputs in a logic mode. In a switch mode, a subset of these fuse points may be programmed with dynamically-created operating signals to form a cross point switch matrix.

Abstract: An integrated circuit includes non-volatile and volatile memory, with the volatile memory controlling the integrated circuit's functionality. Various techniques are disclosed for programming the different types of memory through one or more data ports to provide in-system programmability and dynamic reconfigurability. External configuration devices are not required if the data from the non-volatile memory is transferred directly to the volatile memory.

Abstract: A programmable device and method with generic logic blocks. Each generic logic block is configurable to perform product term logic functions and memory functions, such as RAM, dual-port RAM, ROM, CAM, FIFO and switch.

Abstract: A subscriber conversion system determines at least one code for an existing subscriber of a first wireless communications system to be converted to a second wireless communications system. When the existing subscriber obtains a wireless unit to be used in the second wireless communications system, the conversion system uses the at least one code provided to the existing subscriber to link existing subscriber information from the first wireless communications system to information associated with wireless unit for the second communications system, thereby improving the efficiency of the conversion process. For example, if a service provider wishes to convert from GSM to CDMA, the service provider can provide a secret code and an identification number, such as a directory number (DN), as the codes to the existing GSM subscriber. The subscriber obtains a CDMA wireless unit and commences an activation process to activate the CDMA wireless unit.

Abstract: A ring assembly for a pen has a bottom ring, a top ring, and a slender bridge connecting the bottom ring and the top ring. In assembly, a barrel of the pen extends through the bottom ring and the top ring, so that a sticker adhered around the barrel is securely attached to the barrel by clamping of the top ring and the bottom ring. Furthermore, a gap formed by two conjunct sides of the sticker is concealed by the bridge. By such arrangement, the ring assembly is able to be decorative and to avoid peeling of the sticker from the barrel after long-term use.

Abstract: A dual-purpose pen has a barrel, a cap engaged with the barrel, and a ball point that is extendable from the end of the barrel, and a key-pressing point that is extendable from the end of the cap. The pen can be used for writing when the ball point is extended and for pressing keys when the key-pressing point is extended.
