摘要： A receiver comprises a plurality of antennas (108) for receiving signals originally transmitted as a plurality of different signals, for example from a MIMO (Multi-Input Multi-Output) transmitter. The receiver includes a plurality of coders (302) for applying a respective unique code to each received signal and a summer (306) for combining the coded signals into a single signal which is then down-converted by a single frequency translation stage (202) and digitised. An output signal corresponding to each received signal is obtained by a plurality of detectors (312) with reference to the codes used by the coders. In a preferred embodiment, the unique codes are orthogonal codes such as Walsh codes. The receiver enables a single frequency translation stage to be used to process a plurality of received signals, thereby both saving hardware and reducing the receiver's power consumption.

摘要： A method and system identifying the language of a textual passage is disclosed. The method and system includes parsing the textual passage into n-grams and assigning an initial weight to each n-gram, and adjusting the weight initially assigned to a word or n-gram parsed from the textual passage. The initially assigned weight is adjusted in a manner proportionate to the inverse of the number of languages within which such words or n-grams appear. Reducing the weight assigned to such words or n-grams diminishes—without completely eliminating—their importance in comparison to other words or n-grams parsed from the same textual passage when determining the language of a passage. The method and system of the present invention appropriately weighs the short words or n-grams common to multiple languages without affecting the short words or n-grams that are uncommon to several languages.

摘要： Transistors fabricated on SSOI (Strained Silicon On Insulator) substrate, which comprises a strained silicon layer disposed directly on an insulator layer, have enhanced device performance due to the strain-induced band modification of the strained silicon device channel and the limited silicon volume because of the insulator layer. The present invention discloses a SSOI substrate fabrication process comprising various novel approaches. One is the use of a thin relaxed SiGe layer as the strain-induced seed layer to facilitate integration and reduce processing cost. Another is the formation of split implant microcracks deep in the silicon substrate to reduce the number of threading dislocations reaching the strained silicon layer. And lastly is the two step annealing/thinning process for the strained silicon/SiGe multilayer film transfer without blister or flaking formation.

摘要： An improved molded plastic elbow and a related mold assembly and manufacturing method are provided, wherein the elbow defines an internal flow path having a smoothly radiused inside turn. The elbow is formed by injecting plastic material into a tubular mold cavity formed by closed mold members in cooperation with a pair of slidably retractable core units of circular cross section and having distal ends in mating, angularly set end-to-end contact to form the internal flow path having a turn formed along the length thereof. Each core unit comprises an outer core pin to form an outer portion of the flow path and including a ramped track for slide-fit mounting of an inner slide segment which forms an inner portion of the flow path and further includes a curved inside edge to form a portion of the smoothly radiused inside turn. Initial retraction of each outer core pin from the mold cavity permits relative advancement of the inner slide segment along the ramped track toward a centerline of the flow path, sufficiently for the curved inside edge of the inner slide segment to clear the radiused inside turn of the molded elbow and thereby enable interference-free linear withdrawal of the core unit from the molded plastic part.

摘要： A single-inductor dual-output buck converter facilitates power conversion by converting a single DC power source/supply into two separate DC outputs, each of which can be configured to provide a selected/desired voltage. The converter includes a single inductor and three power switches, which control operation of the converter. The converter has four basic stages of operation in which power is initially supplied to a first output that also stores charge. Subsequently, the stored charge of the first output is employed to provide power to a second output.

摘要： A self-powered awning having a drive assembly with a motor at least partially inserted into an awning roll-up tube for deploying/retracting the awning. The awning uses a rechargeable battery and/or one or more solar panels to charge the rechargeable battery and/or power the awning. Accordingly, the awning can be installed onto a building or vehicle wall without requiring the awning to be wired to the building or vehicle electrical system. The drive assembly and power system can also be retrofitted to existing awnings.
