Abstract: A wireless communication device such as a payment reader has a wireless communication interface and is able to establish wireless pairing with an interactive electronic device such as a merchant device running a point of sale application. In order to establish pairing, the wireless communication device accesses an identifier. The identifier is transmitted to the interactive electronic device via the wireless communication interface, and the interactive electronic device sends the identifier to a pairing server. The pairing server retrieves a passkey based on the identifier and sends the retrieved passkey to the interactive electronic device via a secure connection. The wireless communication device and the interactive electronic device establish wireless pairing based on the retrieved passkey.

Abstract: In some examples, a system and method for pairing a payment object reader with a point-of-sale (POS) terminal is described herein. The payment object reader includes one or more light indicators configured to display information in an optical pattern of one or more colors, brightness, lightness, and intensities, wherein the light indicators display a first optical pattern representative of an operational status of the payment object reader in a first mode, and a second optical pattern representative of a pairing code in a second mode. A display control component, executed by a processor, is configured to control the light indicators in accordance with the pairing code to generate the second optical pattern, the second optical pattern when shared with the POS terminal enables pairing between the payment object reader and the POS terminal. When paired, the payment object reader allows the POS terminal to accept payments from a customer.

Abstract: A payment handling system may operate to handle payments for the cost of a transaction in which one or more devices operate in an offline mode. The payment handling system may allow for merchant devices to make modifications to local versions of an open ticket while in an off-line mode. When a merchant device subsequently enters an online mode, the systems and techniques may operate to reconcile differences between the local versions of the open ticket.

Abstract: A network may be configured to route traffic in such a way as to avoid packet loss in an event of link failure. The network may include a plurality of inner switches and a plurality of outer switches coupled to the plurality of inner switches. Each inner switch may be configured to receive traffic, determine whether a link to a next hop for the traffic is down, and forward the traffic to another outer switch if the link to the next hop is down. Each outer switch may be configured to bounce traffic received from the first inner switch to a second inner switch if the traffic is received as a result of determining that the link from the inner switch to the next hop is down. The second inner switch may then deliver the traffic, or further bounce the traffic off another outer switch.

Abstract: In some examples, a merchant device at a point of sale (POS) location may present information to a merchant in a first language preferred by the merchant, and may present information to a buyer in a second language preferred by the buyer. The merchant device may switch between the different languages in response to detecting a change in the physical orientation of a display. For instance, in a first orientation in which the display is viewable from a merchant direction, the merchant device may present information in the language preferred by the merchant. When the orientation of the display is changed to a second orientation in which the display is viewable from a buyer direction, the merchant device may present information in the language indicated to be preferred by the buyer. Various techniques may be used for determining the preferred language of a particular buyer.

Abstract: A packet switch/router including a first stage switch fabric receiving an electrical signal, a mid-stage buffer receiving and storing the electrical signal from the first stage switch fabric, and a second stage switch fabric receiving the electrical signal from the mid-stage buffer. Each switch fabric includes N layers of N×N arrayed waveguide gratings (AWGs), and each AWG has ingress ports and egress ports. A wavelength tunable device, such as a tunable laser, communicates with a source ingress port of an AWG and converts the received electrical signal to an optical signal having a wavelength selected for routing a packet from the source ingress port to a target egress port of the arrayed waveguide grating. A photoreceiver, such as a burst-mode photoreceiver, receives the propagated optical signal from the target egress port and converts the optical signal to the electrical signal.

Abstract: In some examples, a merchant device may control access to features based on an orientation of a display. For instance, the merchant device may present a first user interface (UI) for enabling a merchant to enter transaction information. Subsequently, the merchant device may present a second UI to enable the buyer to interact toward completion of the transaction, and the merchant may change the orientation of the display to face the buyer. While the display is oriented in the buyer direction, access to the merchant UI is prevented, thereby preventing initiation of a new transaction, cancellation of transaction, etc. When the display is returned to the first orientation, i.e., facing the merchant, the merchant device may enable certain UI features such as for initiating a new transaction, canceling a transaction, or perform other functions that a buyer may have been restricted from performing.

Abstract: A method and apparatus are provided for communicating congestions that area detected in a communications network. According to the method and apparatus, a first Ethernet frame encapsulating a first PDU is transmitted across an Ethernet network. Congestion in the network is then detected, and an indication of the congestion is inserted in a predetermined header field of the first Ethernet frame. Once the first Ethernet frame is received by an endpoint in the network, the indication of congestion is transferred into a second PDU that is associated with the first PDU. The second PDU is then encapsulated in a second Ethernet frame and transmitted towards the sender of the first PDU.

Abstract: Energy proportional solutions are provided for computer networks such as datacenters. Congestion sensing heuristics are used to adaptively route traffic across links. Traffic intensity is sensed and links are dynamically activated as they are needed. As the offered load is decreased, the lower channel utilization is sensed and the link speed is reduced to save power. Flattened butterfly topologies can be used in a further power saving approach. Switch mechanisms are exploit the topology's capabilities by reconfiguring link speeds on-the-fly to match bandwidth and power with the traffic demand. For instance, the system may estimate the future bandwidth needs of each link and reconfigure its data rate to meet those requirements while consuming less power. In one configuration, a mechanism is provided where the switch tracks the utilization of each of its links over an epoch, and then makes an adjustment at the end of the epoch.

Abstract: A domain-specific sentiment classifier that can be used to score the polarity and magnitude of sentiment expressed by domain-specific documents is created. A domain-independent sentiment lexicon is established and a classifier uses the lexicon to score sentiment of domain-specific documents. Sets of high-sentiment documents having positive and negative polarities are identified. The n-grams within the high-sentiment documents are filtered to remove extremely common n-grams. The filtered n-grams are saved as a domain-specific sentiment lexicon and are used as features in a model. The model is trained using a set of training documents which may be manually or automatically labeled as to their overall sentiment to produce sentiment scores for the n-grams in the domain-specific sentiment lexicon. This lexicon is used by the domain-specific sentiment classifier.
