Abstract: Techniques are described for a social networking system to provide community profiles 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 community profiles based on metrics and relationships associated with accounts of the collaborators to the community profile as well as the community profile itself.

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 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: An environmentally controlled chamber system. The system includes an insulated enclosure having an access door and a humidification/dehumidification chamber enclosure arranged and disposed to provide humidification or dehumidification to the insulated enclosure. The system also includes a refrigerant loop having an enclosure evaporator, a dehumidification evaporator, at least one condenser, a variable speed compressor and piping for directing refrigerant from the variable speed compressor to the enclosure evaporator, the dehumidification evaporator, and the at least one condenser. An electrical heating element is arranged and disposed adjacent to the enclosure evaporator to selectively provide heat to at least a portion of the enclosure evaporator. A method for controlling the environmentally controlled chamber system is also disclosed.

Abstract: Systems, methods, and non-transitory computer-readable media can determine a geographical area associated with a crisis. A first user within the geographical area can be identified based on locational data associated with the first user. Information about a safety status of the first user can be actively requested or acquired from the first user. The safety status of the first user can be broadcasted, communicated, or provided to at least a second user associated with the first user.

Abstract: In one embodiment, a method includes determining that an emergency event has occurred. The method also includes determining a geographic area affected by the emergency event. The method also includes determining that a user has entered the geographic area within a pre-determined amount of time after the occurrence of the emergency event. The method also includes sending a prompt to the user to indicate whether the user is safe. The method also includes receiving from the user a response indicating whether the user is safe.

Abstract: In one embodiment, a method includes detecting that a first set of users associated with an emergency event have posted content related to the emergency event on an online social network. The method may also include sending a safety-check prompt to each of one or more users in the first set. The method may also include determining a current-prompting probability based on one or more engagement metrics of the one or more users in the first set. The method may also include sending, in response to determining that the current-prompting probability is above a threshold probability, the safety-check prompt to each of a second set of users. The second set of users may have more users than the first set of users.

Abstract: A rotary medical device configured to be used to prepare a surgical site within a patient for affixing at least one fixation device via a rotary abrading element and a rotary drill bit, both of which are attachable to the same handpiece, is disclosed. By configuring the rotary medical device to operate both a rotary abrading element and a rotary drill bit, the need for a separate, single use drill and the time and human resources needed to disinfect and process the drill is eliminated, thereby saving time and cost. In at least one embodiment, the rotary medical device may include a first detachable system including a first abrading element attached to a first detachable hub, which is attachable to the handpiece, and a second detachable system including a first drill bit attached to a second detachable hub, which is also attachable to the handpiece.

Abstract: In one embodiment, a method includes identifying an emergency event; determining that a threshold percentage of users who are associated with the emergency event have posted content related to the emergency event to an online social network; sending, in response to the determination, a safety-check prompt to each of a first set of users; determining a current-prompting probability based on one or more engagement metrics of the safety-check prompt by the first set of users; and sending, in response to determining that the current-prompting probability is above a first threshold probability, the safety-check prompt to each of a second set of users, wherein the second set of users comprises more users than the first set of users.

Abstract: An advertising campaign maintained by an online system includes an objective, and the online system determines a metric for the advertising campaign based the objective. For example, the online system determines the metric as a ratio of an amount received from an advertiser for presenting the advertising campaign to a number of completed objectives associated with the advertising campaign. Additional advertising campaigns including the objective are identified, and the online system determines metrics for the additional advertising campaigns. The online system compares the metric for the advertising campaign to the metrics for the additional advertising campaign and communicates information to the advertiser based on the comparison.

Abstract: The present invention is system and method for providing a self-calibrating pressure sensor. A pressure sensor apparatus comprises a diaphragm, at least one driving element operably coupled to the diaphragm configured to induce deflection in the diaphragm, and at least one strain gauge coupled to the diaphragm. The at least one strain gauge measures the deflection of the diaphragm. Typically, the driving elements will be piezoelectric drivers and will be operably coupled to the diaphragm. A method for evaluating a pressure sensor comprises inducing deflection in a diaphragm, measuring the deflection, determining the frequency-dependent response, calculating mechanical characteristics of the diaphragm from the frequency-dependent response, and calculating a response coefficient for the diaphragm based in part on said mechanical characteristics. The response coefficient is used to evaluate the sensor. The sensor can then be re-calibrated or self-calibrated based on the response coefficient.

Abstract: A folding work table for mounting to a wall structure so that the folding work table may be folded out of the way when not in use. The folding work table includes a table top with a support leg structure pivotally coupled to a lower face of the table top adjacent a first end edge of the table top. A mounting board is pivotally coupled to a second end edge of the table top. The lower face of the table top has a generally U-shaped track with an elongate channel extending therealong. At least one C-clamp is provided having a generally C-shaped frame has a pair of opposing ends defining a break therebetween. One of the ends of the frame of the C-clamp has a pivot ball slidably disposed in the channel of the track.
