20090077277 | Methods and apparatus for decreasing power consumption and bus activity - Methods and apparatus for enhancing efficiency (e.g., reducing power consumption and bus activity) in a data bus. In an exemplary embodiment, a client-driven host device state machine switches among various states, each comprising a different polling frequency. A client device on the data bus (e.g., serial bus) checks for non-productive periods of polling activity, and upon discovering such a period, informs the host. The state machine then alters its polling scheme; e.g., switches to a lower state comprising a reduced polling frequency, and polling continues at this reduced frequency. In one variant, the client device continuously monitors itself to determine whether it has any data to transmit to a host device and if so, the host is informed, and the state machine restarts (e.g., to its highest polling state). By eliminating extraneous polling, power consumption and serial bus activity is optimized, potentially on both the host and the client. | 03-19-2009 |
20090100275 | Dynamic port power allocation apparatus and methods - Methods and apparatus for dynamically adjusting the amount of power (or current) distributed to one or more connected devices via electrical interfaces. In one embodiment, the apparatus comprises a first module adapted to detect current drawn by a first set of ports, and a second module adapted to adjust the current provided to a second set of ports based on the detected current. The second module is also optionally adapted to distribute unreserved current among the devices according to an allocation protocol. In the exemplary context of a plurality of interconnected serial bus devices, the invention enables a device to draw more current than that required to be reserved for that device (such as to comply with a specification such as USB), yet without increasing the total amount of power which must be dedicated to the serial ports as a whole. Power supply efficiency may also be advantageously optimized. | 04-16-2009 |
20100057946 | TYPE A USB RECEPTACLE WITH PLUG DETECTION - A modified Series A universal serial bus (USB) receptacle connector is equipped with the functionality to allow the electronic system in which it resides to be configured either as a host device or a peripheral device. The modified USB Series A receptacle connector, according to one embodiment of the invention may include a mechanism such as an additional pin or a mechanical switch to detect the presence of a standard USB Series A plug being inserted into it. Upon detection of a plug, an algorithm may allow the system to determine whether it is to act as a host device or a peripheral device and to determine which device supplies power. | 03-04-2010 |

20090063183 | ASSOCIATION OF SUPPORT SURFACES AND BEDS - Systems, methods, beds, supports surfaces and machine readable medium for associating beds and support surface of a healthcare facility are disclosed. A surface association system for a healthcare facility may comprise a plurality of beds. The system may further comprise a computing device and a plurality of support surfaces to be placed upon beds of the plurality of beds. The computing device may associate a support surface of the plurality of support surfaces with a bed of the plurality of beds. The computing device may make the association based upon status data received from the plurality of beds and the plurality of support surfaces. The support surface and/or bed to be associated may initiate a surface association request. The computing device, in response to the surface association request, may request performance of one or more actions on the bed and/or support surface to be associated to identify the bed and/or support surface from the beds and support surfaces of the healthcare facility. | 03-05-2009 |

20120239494 | PRICING DEALS FOR A USER BASED ON SOCIAL INFORMATION - Social networking systems determine price of a deal for a user based on social information associated with the user. For example, multiple users connected via the social networking system may participate in a deal. The price of a deal for a particular user may be determined based on the actions of that user to promote the deal and/or the deal's provider. A user may promote the deal or its provider, for example, by sending explicit messages describing the deal to the user's connections or by posting to a newsfeed that is sent by the social networking system on behalf of the user to the user's connections. Factors considered in determining a price of a deal may include information describing the connections of the user, the actions associated with the deal performed by the user, the connections of the user participating in the deal, and the locations of the user's connections. | 09-20-2012 |
20120239505 | USER INITIATED DEALS IN A SOCIAL NETWORKING SYSTEM - Social networking systems allow users to initiate a deal associated with a provider. A user sends a deal proposal to the social networking system and provides information describing connections of the user that are potential participants of the deal. The social networking system may propose potential participants of the deal to the user. The social networking system determines whether the proposal is acceptable to the provider. The social networking system may send a request to the provider to determine whether the deal is acceptable to the provider. If the proposal is acceptable to the provider, information indicating acceptance of the proposal is sent to the user. If the proposal is not acceptable to the provider, a modified deal proposal may be sent to the user. | 09-20-2012 |
20140089816 | DISPLAYING SOCIAL NETWORKING SYSTEM ENTITY INFORMATION VIA A TIMELINE INTERFACE - A social networking system displays information about a user via a timeline included in a profile page. Narrative data about a user stored in a social networking system, including data about the user and social network activities related to the user is accessed. Timeline units summarizing information about the user are generated from the narrative data. When a viewing user requests a profile page, timeline units are displayed based information related to the viewing user and interactions with the profile page by other users connected to the viewing user. Users that administer the profile page are presented with additional information when viewing the profile page, allowing the administering users to modify appearance of the timeline or to identify actions for an administering user to take to increase interaction with the profile page. | 03-27-2014 |
