  • Publication number: 20130285468
    Abstract: A power over one-pair Ethernet approach. A data transformer is coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. The data transformer enables a network device to transmit and receive data with a link partner device via the single conductor pair. Power transmission over the single conductor pair is enabled through the coupling of a power over Ethernet module to the single conductor pair using a diode that can be paired with a zener diode.

  • Publication number: 20130254565
    Abstract: Embodiments of power sourcing equipment (PSE) utilizing AC disconnect are provided herein. In one embodiment, a PSE is provided that includes a DC supply configured to provide a DC voltage over a data communications medium, a controller configured to provide an AC disconnect signal over the data communications medium, and a parallel inductor-capacitor (LC) circuit coupled between the DC supply and the data communications medium. The parallel LC circuit is configured to isolate the DC supply from the AC disconnect signal. In another embodiment, a PSE is provided that includes a DC supply configured to provide a DC voltage at an output, an inductor coupled between the output of the DC supply and a data communications medium, and a capacitor coupled between the data communications medium and ground. The inductor and capacitor form a series LC circuit configured to generate an AC disconnect signal.

  • Patent number: 8301504
    Abstract: A system and method for allowing a user to schedule pickup of an ordered item provides a user interface having user interface elements for allowing a user to specify a frequency with which an order is it to be picked up, for informing a user as to availability of the item for pickup, and/or for allowing a user to request that an item be held in reserve for pickup within a given period of time, such as 24 hours. Frequency options provided to the user for selection when scheduling an order for pickup may include a one-time frequency, a daily frequency, a weekly frequency, a monthly frequency, and user specified dates. The information as to availability of the item for pickup is determined considering a time of order and real-time stocking information for the item.

  • Publication number: 20120179582
    Abstract: Once a purchaser has proceeded through a check out experience with an online retail system, the settings established during that checkout experience will be applied to future checkout experiences by that purchaser. By capturing and thereafter using checkout settings in this manner, a purchaser can proceed from a shopping cart directly to a checkout review page with the checkout review page being pre-populated with such prior established settings. Furthermore, the methodology allows the purchaser to have a virtually unlimited number of goods in their shopping cart and to have multiple different types of order fulfillment options (e.g., shipping, store pickup, delivery to an organization, etc.) automatically established for those goods.

  • Publication number: 20120159060
    Abstract: Disclosed is a power isolation and backup system. When a power fail condition is detected, temporary storage is flushed to an SDRAM. After the flush, interfaces are halted, and power is removed from most of the chip except the SDRAM subsystem. The SDRAM subsystem copies data from an SDRAM to a flash memory. On the way, the data may be encrypted, and/or a data integrity signature calculated. To restore data, the SDRAM subsystem copies data from the flash memory to the SDRAM. On the way, the data being restored may be decrypted, and/or a data integrity signature checked.

  • Publication number: 20120150681
    Abstract: A retailer computer system facilitates the purchase of products that are determined to be useful in the performance of a task by presenting to a consumer a first user interface by which the consumer may select a task from a repository of tasks, each task stored in the repository of tasks having documented instructions, such as a recipe, for performing the task, by presenting in a web page the documented instructions of the selected task, by using one or more keywords within the documented instructions of the selected task to select at least one product from an electronic product catalog, the selected at least one product being one or more of a part, such as a recipe ingredient, and a tool, such as an appliance, usable in performing the task, and by presenting to the consumer a second user interface for allowing the consumer to purchase via use of an online retail channel the selected at least one product.

  • Publication number: 20120072295
    Abstract: In a database that is associated with the retailer POS system, inventory is flagged as being FSA-eligible and a retailer POS system is programmed to support FSA debit card auto-adjudication, i.e., the retailer POS system is IIAS certified. The FSA-eligible information that is stored in the retailer POS database is also used to flag for a customer FSA-eligible items presented to the user online, e.g., in an online catalog. When an FSA-eligible item is purchased on-line or at a retailer POS, the FSA debit card information is captured and the purchase transaction is processed by the retailer POS system so the customer has easy access to FSA purchases via either channel.

  • Patent number: 8117333
    Abstract: A network device includes at least one input interface, at least one processing path and at least one output interface. The at least one input interface receives data blocks from a plurality of streams in a first order. The at least one processing path processes each of the data blocks, the processing including performing one or more route look-ups for each of the data blocks. The at least one output interface re-orders the data blocks based on a number of the one or more route look-ups associated with each of the data blocks.

  • Patent number: 8044747
    Abstract: A system and method for enabling power applications over a single conductor pair. In one embodiment, data transformers are coupled to a single conductor pair using one or more direct current (DC) blocking elements that preserve an alternating current path. Power is injected onto the single conductor pair after the DC blocking elements and power is extracted from the single conductor pair before the DC blocking elements. Saturation of the data transformers by the injection of power onto the single pair is thereby prevented.

  • Patent number: 7979721
    Abstract: A pay-per-use computer, or other electronic device that uses local security, may use a security module or other circuit for monitoring and enforcement of a usage policy. To help prevent physical attacks on the security module, or the circuit board near the security module, a second circuit may be mounted over the security module to help prevent access to the security module. Both circuits may be mounted on a interposer and the interposer mounted to the circuit board, creating a stack including the first circuit, the interposer, the security module, and a main PC board. When the PC board includes dense signal traces under the security module a three dimensional envelope is created around the security module. When the first circuit is a high value circuit, such as a Northbridge, the risk/reward of attacking the security module is increased substantially and may deter all but the most determined hackers.

  • Patent number: 7956616
    Abstract: A system and method for measuring a cable resistance in a power over Ethernet (PoE) application. A short circuit module in a powered device is designed to produce a short circuit effect upon receipt of a cable resistance detection voltage. The cable resistance detection voltage can be designed to be greater than a voltage for detection or classification and less than a voltage for powering of the powered device. The measurement of the current at a time when a short circuit effect is produced at the powered device enables a calculation of the actual resistance of the cable on a given PoE port.
