Abstract:
Methods and apparatus for accessing modules on a flash memory package concurrently during testing are disclosed. According to one aspect of the present invention, a memory device for storing data includes a plurality of modules and a logic block. The plurality of modules each include a plurality of storage elements that hold the data. The logic block is arranged to enable the plurality of modules to be accessed in parallel, and is also arranged to enable the plurality of modules to be accessed serially.
Abstract:
A serial interface has an input for receiving a digital audio signal and an output for serially outputting bits of the digital audio signal. A shift register includes a serial input connected to the output of the serial interface for storing bits of the digital audio signal. A first-in-first-out (FIFO) buffer has a parallel input connected to a parallel output of the shift register. A digital-to-analog processor is connected to a parallel output of the FIFO. A volume controller initiates loading of bits in the shift register into the FIFO according to a volume control signal to effect a coarse volume adjustment. The volume controller also adjusts resistances of an analog amplifier to effect a fine volume adjustment.
Abstract:
A surface mounted device includes a base body that is mounted on a building or vehicle exterior, and a raised body that is supported and secured on the base body with elongated members. A free space is formed between the base body and the raised body. An opening or openings are facilitated on, and near the center of, the upper surface of the base body, to connect the free space with an internal space of the base body that will be channeled to any other space needing air relief. Alternatively, an opening or openings are facilitated on, and near the center of, the lower surface of the raised body, and channeled to the internal space of the base body through a hollowed raised body and hollowed elongated support members. The base body and the raised body are configured in such a way that the free space between them is narrower at the center than along the perimeter. This forms an airflow path that is first contracting towards the center and then expanding afterwards for any approaching wind direction, providing a venturi mechanism. The device thus creates a low air pressure in the free space near the center and hence a suction effect at said opening, and communicates the suction effect to any space that is connected to the internal space of the base body.
Abstract:
This application discloses a wind pressure-driven air intake device for natural ventilation of zero power consumption. Such a device comprises multiple tunnels being arranged around a common central chamber, each having an inflow valve at its inner end connecting the central chamber and an outer end open to ambient airflow. The inflow valve allows only inward flow from a corresponding tunnel into the central chamber. The central chamber has an opening allowing airflow exit to a space to be ventilated. The device is capable of capturing ambient wind flow and wind pressure to be fed to the vented space regardless of wind flow direction towards the device, with no need for a powered air driver.

Abstract:
A personal audio device including a flexible headband is disclosed. The flexible headband includes a left and right headband portion. The headband has a longitudinal centerline which occupies a substantially single plane. The personal audio device also includes a left earphone, which is secured to a first end of the left headband portion, and a right earphone, which is secured to a first end of the right headband portion. A connector portion connects a second end of the left headband portion with a second end of the right headband portion. The connector portion is linearly adjustable, which enables a distance between the left headband portion and right headband portion to be variable. A change in the distance causes an inversely proportional change in bent compression force applied by a left earphone and applied by the right earphone.
Abstract:
A non-volatile memory storage system is provided. The non-volatile memory storage system includes a memory configured to store a storage system firmware and a non-volatile memory cell array configured to maintain a buffer. A processor in communication with the memory and the non-volatile memory cell array also is included in the non-volatile memory storage system. Here, the processor is configured to execute the storage system firmware stored in the memory. The storage system firmware comprises program instructions for receiving a write command to write data to the non-volatile memory cell array. The write command is allocated a timeout period to complete an execution of the write command. The storage system firmware also comprises program instructions for performing a portion of a garbage collection operation within the timeout period and for storing the data in the buffer.

Abstract:
A flash memory system including a flash memory device and a controller, operable according to an advanced data transfer mode is disclosed. The flash memory device is operable both in a “legacy” mode, in which read data is presented by the memory synchronously with each cycle of a read data strobe from the controller, and in which input data is latched by the memory synchronously with each cycle of a write data strobe from the controller. In the advanced mode, which can be initiated by the controller forwarding an initiation command to the memory, the flash memory itself sources the read data strobe and also a write data strobe that is out-of-phase relative to the read data strobe, and presents data synchronously with one of the edges of that read data strobe. In the advanced mode for a data write, the input data is presented by the controller synchronously with a selected edge of both the write data strobe and the read data strobe. The voltage swing of the data and control signals is reduced from conventional standards, to reduce power consumption.
Abstract:
Methods and systems for binning defects detected on a specimen are provided. One method includes comparing a test image to reference images. The test image includes an image of one or more patterned features formed on the specimen proximate to a defect detected on the specimen. The reference images include images of one or more patterned features associated with different regions of interest within a device being formed on the specimen. If the one or more patterned features of the test image match the one or more patterned features of one of the reference images, the method includes assigning the defect to a bin corresponding to the region of interest associated with the reference image.
