  • Patent number: 9412127
    Abstract: Methods and systems for assessing the quality of an item listing are described. In an example embodiment, a listing quality score for an item listing is derived as a weighted sum of first and second parts. The first part represents a predicted score based on a comparison of item attributes for the item listing that are known at listing time, with item attributes of similar item listings that have historical data available for assessing their actual performance. The second part is based on one or more observed demand metrics representing actual historical performance of the item listing. The weighting factor is derived, such that over time, the emphasis shifts from the predicted to the observed score.

  • Patent number: 9384278
    Abstract: A system and method for assessing excessive accessory listings in search results includes a processor-implemented textual mining module that parses a data field of a document and generates at least one token from the data field. A processor-implemented scoring module calculates a score for the at least one token, with the at least one token score representing a likelihood that the at least one token belongs to one of two binary classifications. The processor-implemented scoring module also calculates a score for the document based on the at least one token score, with the document score representing a probability of the document being in one of the two binary classifications. A processor-implemented decision tree module inputs the document score and document attribute values into a decision tree and generates an output representing a refined score based on the document score and at least one of the document attribute values.

  • Patent number: 9320163
    Abstract: Disclosed is a portable downloader comprising a pen-shaped housing and a circuit board provided inside of the pen-shaped housing. Provided at one end of the circuit board is a micro-universal serial bus (MUSB) port. Connected to the circuit board are a ground wire and two data wires. Each data wire is connected to a probe at the other end. Provided at the end of the pen-shaped housing corresponding to the MUSB port is a socket. Provided at the other end are two position-fixing holes. The two probes penetrate the position-fixing holes. The MUSB port connects to a computer universal serial bus (USB) port through a USB-MUSB computer extension wire. The portable downloader uses USB power supply with no need for an external power supply, and supports hot plug. The downloader uses the two probes as the C2 port, and is convenient to transmit data to C2 slave devices. The downloader is of a pen-shaped packaging, and is therefore easy to carry.

  • Patent number: 9274789
    Abstract: An in-application upgrade method is used for optical module firmware not breaking a service. A storage area for internal programs of an optical module is divided into two areas which are respectively used for storing upgrade and application programs, and is divided into an area for backing up an interrupt vector table of a Boot program. An upper computer is in communication with the optical module. The interrupt vector table is switched, and the jump between the Boot program and the application program is achieved. The method includes extracting the contents of firmware, entering a download mode and updating the firmware. The original firmware is erased, and new firmware is written. An application mode is entered, the upper computer sending an exit command from the download mode. The upgrade program exits and a new application program is executed. The optical module operates normally without interruption.

  • Publication number: 20150194311
    Abstract: A method for forming a semiconductor device includes forming a gate structure over a substrate, performing a lightly-doped drain (LDD) implantation of first dopant ions into the substrate using the gate structure as a mask to form LDD regions in the substrate, performing, after the LDD implantation, a pre-amorphization implantation (PAI) into the substrate using the gate structure as a mask to pre-amorphize at least a portion of the LDD regions, and performing, after the PAI, a high-doping implantation of second dopant ions into the substrate using the gate structure as a mask to form highly-doped regions at least partially overlapping the LDD regions.

  • Publication number: 20150161635
    Abstract: In an example embodiment, a pseudo product group for an item to be listed in an online marketplace having unstructured data is determined. Then, a fair market price for the item is determined using past data from listings in the pseudo product group. The fair market price may be used as a reference price in a curve of price elasticity versus price to obtain a price elasticity value. A price range may then be recommended to a user for the listing based upon the fair market price and the price elasticity value.

  • Patent number: 8848609
    Abstract: Techniques are provided for a foreign controller to receive a handoff message including information for a multicast group that is used to forward network control information originating from an Internet Protocol version 6 (IPv6) network router by a home wireless controller to one or more foreign wireless controllers for mobile client devices that were first associated with the home controller. The foreign controller joins a multicast group based on the information contained in the handoff message and establishes a communication path with a mobile client device. The foreign controller extracts network control information addressed to the mobile client device received from the home wireless controller via a multicast stream associated with the multicast group, and forwards the network control information to the mobile client device via the communication path.

  • Publication number: 20140264528
    Abstract: A non-volatile memory structure includes a source and a drain. The memory structure includes a substrate and a dielectric layer on the substrate. The memory structure further has a gate, which can be a floating gate, on the dielectric layer. A recess is on the drain side and nearest to the bottom corner of the dielectric layer. The recess is configured to reduce the electric field density around the bottom corner nearest to the drain in order to reduce the damage on the dielectric layer when the memory is under a bias.

  • Patent number: 8112552
    Abstract: In accordance with one or more aspects of the default peripheral device selection based on location, a current location of a computing device is obtained. A mapping record of default peripheral devices to locations is accessed to identify a default peripheral device corresponding to the current location of the computing device, and the identified default peripheral device is returned as a current default peripheral device for the computing device. Additionally, an identification of a peripheral device to be a default peripheral device can be received. A mapping of the current location of the computing device to the identified default peripheral device can also be stored.
