Abstract: A client device may be used to initiate or answer calls using a host device connected to a network. For example, when a phone operating as a host device receives an incoming call from a network, the phone may communicate the presence of the incoming call to one or more client devices such as laptop, desktop, tablet, or wearable devices that are associated with the host device. When an answer call selection is made at a client, a call answered communication may be sent from the client device to the host device. The host device may then communicate with the network to connect the call to the host, and when the call is connected, the host may hand-off the call to the client that sent the call answered communication.

Abstract: A blade has an airfoil, and the blade is configured for use with a turbomachine. The airfoil has a throat distribution measured at a narrowest region in a pathway between adjacent blades, at which adjacent blades extend across the pathway between opposing walls to aerodynamically interact with fluid flow. The airfoil defines the throat distribution, and the throat distribution reduces aerodynamic loss and improves aerodynamic loading on the airfoil. The airfoil has a linear trailing edge profile.

Abstract: An electronic direction system accesses navigation data describing at least one instance in which a direction was missed during provision of electronic navigation along a route and tracks instances in which directions have been missed based on the accessed navigation data. The electronic direction system accounts for the tracked instances in which directions have been missed in handling provision of future directions.

Abstract: Techniques are described for monitoring whether a user is following directions to a destination during electronic navigation to the destination provided by an electronic navigation device. When the electronic navigation device determines that the user is not following directions to the destination (e.g., the user has missed several turns suggested by the electronic navigation device), the electronic navigation device determines that the user appears to be avoiding the route (or a primary component thereof) to the destination. In response to a determination that the user appears to be avoiding the route (or a primary component thereof) to the destination, the electronic navigation device may automatically, without human intervention, perform an operation directed to using an alternative route (or alternative primary component) to the destination despite the current route remaining preferred according to current routing settings.
