摘要:
Methods and apparatus for interfaces to manage inter-regional connectivity for direct network peerings. A system may include a connectivity coordinator, a first resource collection in a first geographical zone and a second resource collection in a second geographical zone. The coordinator implements a programmatic interface defining connectivity operations. The coordinator receives a request via the interface to establish a logically isolated network path to the second resource collection on behalf of a client that has a dedicated physical link set up to connect to the first resource collection. In response to the request, the coordinator performs one or more configuration operations to enable traffic to flow from the client's network to the second resource collection over a logically isolated network path using the dedicated physical link.

Techniques are described for providing users with access to computer networks, such as to enable users to create computer networks that are provided by a remote configurable network service for use by the users. Such provided computer networks may be configured to be private computer networks accessible only by the users who create them, and may each be created and configured by a client of the configurable network service to be an extension to an existing computer network of the client, such as a private computer network extension to an existing private computer network of the client. In addition, access to remote resource services may be configured and provided from such computer networks in various manners, such as to include a local access mechanism as part of a provided computer network that is configured to forward communications sent to the access mechanism to a particular remote resource service.

A network-based service may generate notifications regarding items of interest to a user. A contact selection service may receive the notifications and generate a user interface for transmission of the notification to the user. The generated user interface may include a unique identifier and may further enable the user to submit user contact information to request contact with a service agent. The contact selection service may further pre-authorize contacts between users and customer service agents CSA. The unique identifier, and optionally the submitted user contact information, may be employed by the contact selection service to selectively determine which customer contact requests received by the contact selection service are pre-authorized for contact with a CSA and enables such contacts between customers and CSAs to proceed.

Techniques are described for providing users with access to computer networks, such as to enable users to interact with a remote configurable network service to create and configure computer networks that are provided by the configurable network service for use by the users. Secure private access between a computer network provided for a user by the configurable network service and one or more other remote computing systems of the user (e.g., a remote private network) may be enabled in various ways. For example, a user may programmatically invoke an API provided by the configurable network service to obtain assistance in establishing remote access from a remote location to a provided computer network of the configurable network service, such as to establish a VPN connection from the remote location to the provided computer network using hardware and/or software supplied to the remote location in response to the API invocation.

A bicycle handle with a resistance mechanism is provided such that the combination of the force that the user provides and that the resistance mechanism provides is a zero force directed towards steering the bicycle. The user provides a force on the bicycle handle which in turn overcomes the resistance mechanism to provide linear movement. A repetition of this movement provides a means of strengthening or maintaining the muscle tone of the user's upper body while they are riding the bicycle, thus providing a means of simultaneous exercise for the user's upper and lower body and back.

A system and associated processes for consolidating and replacing various forms of payment (e.g. credit cards, debit cards, and cash) with a single payment system is presented. A client system can read a machine-readable code generated by a merchant system associated with a merchant, or other product or service provider, and present the information encoded by the machine-readable code to a customer. Upon receiving confirmation that the customer desires to proceed with the transaction, the client system can initiate payment by contacting a payment system associated with the customer. This payment system can then transfer payment to the merchant by, for example, transferring cash from the customer's account or using credit associated with the customer's account. Thus, embodiments of the present disclosure enable a customer to complete a transaction without using, for example, cash, a credit card, or a debit card.

Techniques are described for providing managed virtual computer networks that may have a configured logical network topology with one or more virtual networking devices, with corresponding networking functionality provided for communications between multiple computing nodes of the virtual computer network by emulating functionality that would be provided by the networking devices if they were physically present. In some situations, the emulating of networking device functionality includes receiving routing communications directed to the networking devices and using included routing information to update the configured network topology for the managed computer network. In addition, the techniques may further include supporting interactions with devices that are external to the virtual computer network, including remote physical networking devices that are part of a remote computer network configured to interoperate with the virtual computer network, and/or specialized network devices that are accessible via a substrate network on which the virtual computer network is overlaid.
摘要:
A photodisplay device in which an optically addressed image can be viewed indefinitely, erased and readdressed with a new image is disclosed. Optically responsive reversible photochiral materials are incorporated into a bistable cholesteric liquid crystal in an electrooptic display cell. A high resolution image exposed on the cell is fixed by a low voltage pulse to unpatterned electrodes and can be, at a later time, erased with a high voltage pulse.
摘要:
A system for the detection of ligands comprising at least one receptor and an amplification mechanism coupled to the receptor wherein an amplified signal is produced as a result of receptor binding a ligand. Examples of suitable amplification mechanisms include antibody-embedded liquid crystalline materials; use of alpha-2-macroglobulin to encage an enzyme, whereby the enzyme is separated from its substrate by an receptor; and a receptor engineered to inhibit the active of site of an enzyme only in the absence of a ligand. Also provided are methods for the automatic detection of ligands.
