20130232350 | Accessory Device Authentication - 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. | 09-05-2013 |

20140132550 | Electrical Contacts and Connectors - 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. | 05-15-2014 |
20150089248 | Accessory Device Power Management - 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. | 03-26-2015 |

20090143502 | Aqueous dispersions utilizing carboxyalkyl cellulose esters and water reducible polymers - Aqueous dispersions containing hydrophobic materials that are useful as reduced volatile organic content may be utilized as a coating, a stain, a resin, a polymer, or an additive. Specifically, the aqueous dispersion may contain one or more of a carboxyalkyl cellulose ester, such as carboxymethyl cellulose acetate butyrate, a fluorosurfactant, such as a polyoxetane fluorosurfactant or a fluoroaliphatic polymeric ester based surfactant, a water dispersible resin, and optionally, a C-11 ketone and/or surfactant. | 06-04-2009 |
20110104501 | Emulsions Useful for Coatings and Coating Additives - The invention relates to a method of preparing aqueous emulsions of resins and additives, to provide coating compositions and additives which maintain solvent-like application and performance properties yet have reduced volatile organic content. The compositions and additives contain an organic phase, an aqueous phase, and an emulsifier. The emulsifier is preferably a polyolefin aminoester, a substituted alkanolamine, or a mixture thereof, a polyalkylene glycol ether, or an orange oil emulsifier. The compositions of the invention are particularly useful as coatings and coating additives that are applied to substrates, such as wood and plastics. | 05-05-2011 |
