Abstract: A method of triggering a desired operating mode in a universal serial bus (USB)-compatible client device is provided. A USB-compatible client device detects that it has been coupled to a USB-compatible host device via a USB bus. The USB-compatible client device attempts to pull a data line of the USB bus high. The USB-compatible client device then ascertains that the data line remains pulled low, thereby indicating that the USB-compatible client device should enter a first mode of operation. The USB-compatible client device operates according to the first mode of operation.

Abstract: Apparatuses and methods to distinguish proprietary, non-floating and floating chargers for regulating charging current are disclosed. In one aspect, a charger detection circuit is provided in a portable electronic device. The charger detection circuit is configured to detect whether a connected Universal Serial Bus (USB) charger is compliant with a USB battery charging specification. If the connected USB charger is non-compliant with the USB battery charging specification, the charger detection circuit is configured to further detect if the non-complaint USB charger is a non-compliant floating USB charger or a non-compliant proprietary USB charger. If the connected USB charger is determined to be a non-compliant proprietary USB charger, the portable electronic device can be configured to draw up to a maximum charging current according to the USB battery charging specification.

Abstract: Apparatuses, methods, and systems for enabling higher current charging of Universal Serial Bus (USB) Specification Revision 2.0 (USB 2.0) portable electronic devices from USB 3.x hosts are disclosed. In one aspect, a USB 2.0 controller is provided in a USB 2.0 portable device. A USB 3.x controller is provided in a USB 3.x host. The USB 2.0 controller is configured to draw a higher charging current than specified in USB 2.0 for the USB 2.0 portable device over a USB 2.0 cable. In order to draw the higher charging current without violating USB 2.0, the USB 2.0 controller is configured to use one or more reserved elements in an existing USB 2.0 descriptor(s) or bitmap(s) to indicate a higher charging current request from the USB 2.0 controller.

Abstract: Electronic devices are adapted to facilitate detection of a type of USB charger to which an electronic device is connected. According to one example, an electronic device can apply a current source to a data line of a USB plug coupled to a USB port. A determination can be made whether the data line has gone to a LOW state or remained at a HIGH state after a predetermined period of time. If the data line has gone to a LOW state, the USB port may be identified as a downstream port, such as a standard downstream port (SDP) or a charging downstream port (CDP). If the data line has remained at the HIGH state, the USB port may be identified as a dedicated charging port (DCP), no matter if it is compliant or non-compliant with the BC 1.2 spec. Other aspects, embodiments, and features are also included.

Abstract: A facility for guiding users through a series of steps or tasks, often associated with a process, is described. The facility assigns tasks or steps to users having roles identified with the task or step. The role associated with the task or step may change depending on the state of the task or step. When the role associated with a task or step changes, the facility may assign the task or step to another user. The facility guides a user through a task or step by providing instructions and other information, such as data tables and user input fields, that may be used to complete the task or step. The facility provides for the definition of processes by allowing users to specify tasks, steps and instructions relating to processes.

Abstract: A framework is presented that can be used to create and execute software applications that include a user interview. The framework includes run-time engines and a data repository. The run-time engines include an interview driver. The data repository includes interview instructions and model information. The interview driver generates or modifies an instantiated data model by using the interview instructions and model information to obtain information from a user. The interview instructions include flow control information, prompts, and user interface (UI) information. There are three types of prompts: AskExist, AskDetail, and AskChange. A prompt is associated with an element. A prompt is created manually or using a template. A prompt is customized based on info known about the user.

The interview driver generates or modifies an instantiated data model by using the interview instructions and model information to obtain information from a user.

The flow control information specifies how to traverse a graph of the data model and can include, for example: pre-defined sequence, rules/heuristics (including idea of groups), graph-search, or combination; discover vs. explore data model element; once discovered, explore immediately vs. defer until later.

The interview driver generates or modifies an instantiated data model by using the interview instructions and model information to obtain information from a user.

Once an instantiated model has been created, it can be used to generate an application-specific document, such as a tax form. A transformer and application logic are used to generate an instantiated application-specific model. The instantiated application-specific model and the document renderer are used to generate an application-specific document.
