Abstract: Reversible connectors for accessory devices are described. In one or more implementations, a connector cable for an accessory of a host computing device is configured such that a head of the connector cable may be plugged into a corresponding port of the host in either orientation (straight or reverse). The host computing device is configured to sample signals associated with allocated pins of the connector to detect connection of the connector to an accessory port and to ascertain an orientation of the connector. A combination of high and low values of signals conveyed via these allocated pins upon insertion of the connector may be used by a controller of the host to distinguish between different types of devices and to resolve the orientation of the connector cable. A switching mechanism of the host computing device may then be configured to automatically route signals accordingly.

Abstract: The invention is a device and a method for delivering a dose of a pharmaceutical agent to the eye. The device and method provide a safe and effective way to instill a specified dose of the agent to the eye virtually independent of gravity and posture. The device includes a filter matrix in which the fluid capture and release properties can be modified. The filter matrix is attached to a flexible handle with an impermeable or semipermeable membrane there between.

Abstract: Power management contracts for accessory devices are described. In one or more implementations, a power management contract is established for a system including a host computing device and an accessory device based at least in part upon power exchange conditions observed for the system. The power management contracts define operating constraints for power exchange between components of the system, including at least a power exchange direction and current limits. The host computing device and accessory devices are each configured to renegotiate the power management contract to dynamically change operating constraints in “real-time.” Additionally, different power management contracts may be associated with identifying data corresponding to different types of accessory devices.

Abstract: Accessory device power management techniques are described in which a power exchange state for a system including a host computing device, an accessory device, and an adapter is recognized. Power exchange states may be defined according to relative states of charge (RSOC) and connection status for the system components and mapped to power management control actions. Responsive to the recognition of a current power exchange state, corresponding power management control actions may be ascertained and applied to jointly manage power for the system. For instance, the host device may draw supplemental power from a power source associated with an accessory device (e.g., a battery or power adapter) or supply power for use by the accessory device according to different states. Power exchanges may also be managed in accordance with capabilities of the accessory device identified based on authentication of the accessory device.

Abstract: Accessory device authentication techniques are described. In one or more embodiments, connection of an accessory device to a host computing device is detected. Responsive to the detection, an authentication sequence may occur to verify an identity and/or capabilities of the accessory device. Upon successful authentication of the accessory device, the host device may authorize the accessory device for power exchange interactions with the host device. The host device may then draw supplemental power from a power source associated with the authorized accessory device, such as a battery or power adapter. The host device may also enable the accessory device to obtain and use power supplied by the host device in some scenarios. Power exchange between a host device and an authorized accessory may be managed in accordance with capabilities of the accessory device that are identified during authentication.

Abstract: An input device is disclosed that includes keys on a first surface and a second surface of the input device. At least some of the keys are operably coupled to a matrix including a switch for each key therein. When one of the keys is pressed, the corresponding switch is activated to provide a signal indicative thereof.

Abstract: Electrical contact and connector techniques are described. In one or more implementations, a computing system includes a computing device and an input device that are configured to be physically and communicatively coupled using a projection that is configured to be disposed within a channel, communication contacts that are configured to contact contacts within the channel to support the communicative coupling; and a protrusion disposed on the projection, the protrusion configured to be received within a cavity formed as part of the channel. The protrusion includes an electrical contact that is configured to be self-cleaning due to movement of the protrusion in relation to the cavity and is configured to transfer power between the input device and the computing device.
