  • Patent number: 6697383
    Abstract: Magic Packet technique is developed to remotely awake a computer host in a sleeping mode on a node through computer network. Instead of utilizing a large amount of memory or a complex algorithm, an algorithm and system, which only utilize two sets of counters and control logics to perfectly detect the Magic Packet according to the characteristics of magic packet are disclosed. According to the present invention, if a LAN controller on a node of the network is in magic packet mode, it will detect all input frames addressed in the node to search a specific data sequence indicative of the Magic Packet frame. Once the controller detects the data sequence, it will notice the power management circuitry of the computer host on the sleeping node to awake the system.

  • Publication number: 20040010329
    Abstract: A method for reducing buffer requirements in a digital audio decoder. Firstly, N samples that have to be decoded for an audio channel at this time are extracted from a sub-frame of a bitstream. A sub-block of K PCM samples is calculated at a time by performing an inverse transform on the N extracted samples, and then the N extracted samples are discarded. Note that the number of extracted samples is greater than or equal to the number of the PCM samples in a generated sub-block, i.e., N≧K. The above steps are repeated until one PCM output sub-frame of the audio channel is fully obtained.

  • Patent number: 6660975
    Abstract: Methods and structures are provided for extremely flat wafer chucks, allowing close thermal contact uniformly across a semiconductor processing substrate. An upper and a lower section are tightly fit to one another with flat inner surfaces in face-to-face contact. The sections also define at least one groove therebetween. The two sections have asymmetrical thickness, but the groove defined therebetween is correspondingly asymmetrical such that the groove is centered in the assembled chuck. A heater element, such as a resistive heater, is placed within the groove with some clearance prior to assembling the upper and lower sections. After assembly and tightening, the chuck is thermally cycled above the normal operating temperature prior to secondary machining, thus assuring flatness that is maintained during high temperature operation.

  • Patent number: 6650146
    Abstract: A digital frequency comparator includes two double-edge triggered flip-flops and a combination logic. Each of the double-edge triggered flip-flops includes two D-type flip-flops and two multiplexers. The first D-type flip-flop receives a first reference clock pulse and is triggered by a data signal. The second D-type flip-flop receives the first reference clock pulse and is triggered by the reverse of the data signal. The first multiplexer provides the output of the first D-type flip-flop when the data signal is 1 and the output of the second D-type flip-flop when the data signal is 0. The second multiplexer provides the output of the first D-type flip-flop when the data signal is 0 and the output of the second D-type flip-flop when the data signal is 1. The combination logic enables an UP pulse when the data signal transmission clock is faster in frequency than the first reference clock signal.

  • Patent number: 6643718
    Abstract: A barrier control scheme controls the order dependency of items in a multiple FIFO queue structure. The barrier control scheme includes a cycle ID generator, a barrier bit/barrier ID generator and a cycle ID and barrier ID comparator. Each incoming item to the FIFOs is assigned a cycle ID. If an incoming item of a first FIFO has order dependency on items of a second FIFO, a barrier bit is set and a barrier ID is determined and generated by the barrier bit/barrier ID generator. The barrier bit and barrier ID are inserted in the first FIFO along with other fields of the incoming item. When an item is to be consumed, the cycle ID and barrier ID comparator compares its barrier ID and the cycle IDs of items in the second FIFO. The item to be consumed is blocked until all items on which the item is dependent are consumed in the second FIFO.

  • Publication number: 20030186482
    Abstract: Elements of a sensor system are encapsulated into a single package. The sensor elements are covered with a flexible gel coat and then inserted into a molding tool cavity. Each element may be individually coated with a gel blob, or all elements may by coated with a single gel blob. One or more retractable pins are incorporated into the molding tool and in their normal position are each in contact with the gel. A molding compound is injected into the cavity so as to encapsulate the device and gel coat. When the pins are extracted and the device ejected from the molding cavity, one or more passageways in the molding are left defined by the pins. The passageways expose the flexible gel covering the device elements to the atmosphere. For pressure sensitive elements, the gel, being flexible, transfers the local air pressure to the pressure sensitive element. For optical elements, the exposed gel is preferably removed to allow for the passage of radiation to and from the device elements.
