Abstract: The technology relates to partially redundant equipment architectures for vehicles able to operate in an autonomous driving mode. Aspects of the technology employ fallback configurations, such as two or more fallback sensor configurations that provide some minimum amount of field of view (FOV) around the vehicle. For instance, different sensor arrangements are logically associated with different operating domains of the vehicle. Fallback configurations for computing resources and/or power resources are also provided. Each fallback configuration may have different reasons for being triggered, and may result in different types of fallback modes of operation. Triggering conditions may relate, e.g., to a type of failure, fault or other reduction in component capability, the current driving mode, environmental conditions in the vicinity of vehicle or along a planned route, or other factors.

Abstract: Techniques are described for a social networking system to provide group or aggregation accounts that allow users to easily and quickly form relationships with multiple other users based on a membership association of the multiple users to the group account. In some cases, the social networking system may be configured to add and/or remove relationships based on changes in association between members and the group account.

Abstract: Techniques are described for a social networking system to provide collective accounts that allow for multiple holders, editors, and/or managers. In some cases, the social networking system may be configured to distribute content associated with the collective accounts based on metrics and relationships associated with accounts of the contributors to the collective account as well as the collective account itself.

Abstract: Techniques are described for a social networking system to enable multiple users to collaboratively create, publish, receive attribution, and/or edit content. In some cases, the social networking system may be configured to distribute the collaborative content and feedback associated therewith based on metrics and relationships between collaborators of the collaborative content and users of the social networking system.

Abstract: A housing for a flourescent tube wherein the end caps are formed to interengage the end caps of an adjacent housing thereby enabling the formation of a variable length display panel. A large area advertisement can be removably secured to the panel which provides backlighting. Each end cap is provided with a removable section to permit access to the housing interior and replacement of the flourescent tube or ballast therein.

Abstract: A water-activated alarm system, providing an alarm in the event of a water leak, includes a radio-frequency transmitting unit and a receiving unit and a number of safety features to ensure proper operation in the event of an emergency. The transmitting unit includes a flood detector having electrodes to be placed in a flood prone area, a tone encoder, for sending an encoded signal in the event of a flood, and means to provide visible and audible alarm indications, including a buzzer and a user-programmable digital voice circuit for identification of the area in which a flood occurs.
