  • Patent number: 7884276
    Abstract: Methods, systems, and devices are described for automatically converting audio input signal data into musical score representation data. Embodiments of the invention identify a change in frequency information from the audio signal that exceeds a first threshold value; identify a change in amplitude information from the audio signal that exceeds a second threshold value; and generate a note onset event, each note onset event representing a time location in the audio signal of at least one of an identified change in the frequency information that exceeds the first threshold value or an identified change in the amplitude information that exceeds the second threshold value. The generation of note onset events and other information from the audio input signal may be used to extract note pitch, note value, tempo, meter, key, instrumentation, and other score representation information.

  • Patent number: 7884826
    Abstract: Methods and apparatus are disclosure for maintaining realistic grooming of simulated objects. In a method for simulating objects, a reference shape associated with a simulated object is received. A predetermined orientation is also received. A force acting on the simulated object is then modified based on the predetermined orientation. The force acts on the simulated object to shape the simulated object according to the reference shape. The force may be “strategically weakened” when the simulated object (or a portion thereof) is substantially aligned with the predetermined orientation. In a further method for simulating objects, a measured height associated with the simulated object is received. A “lifting” force is generated to reduce a difference between the measured height and a predetermined height associated with the reference shape. The lifting force simulates structure and internal forces that provide volume and shaping to physical objects, such as hair.

  • Patent number: 7884831
    Abstract: Circuits, methods, and apparatus that provide texture caches and related circuits that store and retrieve texels in a fast and efficient manner. One such texture circuit provides an increased number of bilerps for each pixel in a group of pixels, particularly when trilinear or aniso filtering is needed. For trilinear filtering, texels in a first and second level of detail are retrieved for a number of pixels during a clock cycle. When aniso filtering is performed, multiple bilerps can be retrieved for each of a number of pixels during one clock cycle.

  • Patent number: 7877999
    Abstract: A thermodynamic engine is configured to convert heat provided in the form of a temperature difference to a nonheat form of energy. Heat is directed through a heating loop in thermal contact with a first side of the thermodynamic engine. A second side of the thermodynamic engine is coupled to an environmental cooling loop in thermal contact with an environmental cooling device. The thermodynamic engine is operated to dispense heat from the second side of the thermodynamic engine through the environmental cooling loop into the environmental cooling device. Operation of the thermodynamic engine thereby generates the nonheat form of energy from the temperature difference established between the first side and the second side of the thermodynamic engine.

  • Patent number: 7879729
    Abstract: In a method of forming micro patterns of a semiconductor device, first etch mask patterns are formed over a semiconductor substrate. An auxiliary film is formed over the semiconductor substrate including a surface of the first etch mask patterns. Second etch mask patterns are formed between the auxiliary films formed on sidewalls of the first etch mask patterns. The first etch mask patterns and the second etch mask patterns are formed using the same material. The auxiliary films between the first and second etch mask patterns are removed. Accordingly, more micro patterns can be formed than allowed by the resolution limit of an exposure apparatus while preventing misalignment.

  • Patent number: 7882292
    Abstract: An arbiter decides to grant access from multiple clients to a shared resource (e.g. memory) using efficiency and/or urgency terms. Urgency for a client may be determined based on an “in-band” request identifier transmitted from the client to the resource along with the request, and an “out-of-band” request identifier that is buffered by the client. A difference between the out-of-band request identifier and the in-band request identifier indicates the location of the request in the client buffer. A small difference indicates that the request is near the end of the buffer (high urgency), and a large difference indicates that the request is far back in the buffer (low urgency). Efficiency terms include metrics on resource overhead, such as time needed to switch between reading/writing data from/to memory via a shared memory bus, or bank management overhead such as time for switching between DRAM banks.

  • Patent number: 7880216
    Abstract: In a method of fabricating a flash memory device, trenches are formed in an isolation area of a semiconductor substrate. A first insulating layer is formed on sidewalls and bottoms of the trenches. Conductive layer patterns are formed on the first insulating layers at the bottoms of the trenches. A second insulating layer is formed on the conductive layer patterns. Gate lines are formed over a semiconductor substrate including the second insulating layer. The gate lines intersect the conductive layer patterns. Junctions are formed on the semiconductor substrate between the gate lines. An interlayer insulating layer is formed over the semiconductor substrate including the gate lines. Contact holes are formed through which the conductive layer patterns and the junctions located on one side of the conductive layer patterns are exposed. The contact holes are gap-filled with a conductive material, thereby forming contact plugs.

  • Patent number: 7882021
    Abstract: System and methods for facilitating the settlement of financial accounts across different entities utilize a host computer system that tracks financial transactions made at each merchant location or store and uses this information to reconcile accounts across different entities. In one embodiment, the host computer periodically performs a net settlement analysis of the transactional data received from each entity's stores. A request is prepared to transfer funds from each entity's bank account having a positive net settlement amount into a central entity bank account. A request is also prepared to transfer funds into each entity's bank account having a negative net settlement amount from the central entity bank account.
