Abstract: A leg mechanism includes an articulated leg system, a passive device and a cable. The articulated leg system has a leg portion. The passive device is coupled to the articulated leg system and is configured to apply a first force to a portion thereof. The cable is coupled to the articulated leg system and is configured to apply a second force, in opposition to the first force, to a portion thereof. When the cable is drawn away from the articulated leg system, the second force moves the leg portion in a first direction. When tension is released from the cable, the passive device exerts the first force so as to move the leg portion a second direction that is opposite the first direction.

Abstract: A leg mechanism includes an articulated leg system (100), a passive device (130) and a cable (134). The articulated leg system (100) has a leg portion (128). The passive device (130) is coupled to the articulated leg system and is configured to apply a first force to a portion thereof. The cable (134) is coupled to the articulated leg system (100) and is configured to apply a second force, in opposition to the first force, to a portion thereof. When the cable (134) is drawn away from the articulated leg system (100), the second force moves the leg portion (128) in a first direction. When tension is released from the cable (134), the passive device (130) exerts the first force so as to move the leg portion (128) a second direction that is opposite the first direction.

Abstract: A sensing device includes a pressure sensor and a deformable cover. A fluid cavity engineered between the deformable cover and the pressure sensor changes shape and ultimately collapses as force is applied to the sensing device. The shape and collapse of the engineered cavity, along with the entire structure of deformable cover and the pressure sensor, govern the force vs. pressure behavior of the sensing device and can be tailored as desired. A first benefit includes providing tailored properties of the sensing device by varying the structure of the deformable cover. A second benefit includes that if too much force is applied, excess force—beyond that which is required to collapse the engineered cavity—does not produce excess pressure which would cause damage to the pressure sensor. As such the sensing device is protected from accidental, or intended, over loading.

Abstract: An exemplary embodiment of the present invention provides a sensing device comprising a pressure sensor, a sensor housing, and a deformable cover. The sensor housing comprises a sensor cavity disposed within the sensor housing. The pressure sensor is disposed within the sensor cavity. The deformable cover is disposed adjacent to the sensor housing. The deformable cover comprises a deformable cavity. The deformable cavity is in fluid communication with the sensor cavity. The deformable cavity and the sensor cavity contain a fluid, such that when an external force is applied to a surface of the deformable cover, the deformable cavity deforms and alters a volume of the deformable cavity to alter a pressure sensed by the pressure sensor.

Abstract: In one embodiment, a method includes receiving, from a client system of a first user of an online social network, an unique identifier associated with a second user of the online social network, the unique identifier being sent responsive to a communication between the second user and the first user, accessing a social graph including first and second nodes corresponding to the first and second users, respectively, identifying the second user based on the unique identifier, retrieving profile information associated with the second user and a privacy setting associated with the second user, determining whether the information is visible to the first user based on the privacy setting and a degree of separation in the social graph between the first node and the second node, and sending, to the client system, the profile information that is visible to the first user for display in association with the communication.

Abstract: Techniques for prompting communication among members of a social network are described. A social server may include an interaction detection component configured to detect a user interaction of a first user with an information unit. An information component of the social server may be configured to store an association between the first user and the information unit. A correlation component of the social server may be configured to correlate the first user with one or more other users based upon one or more stored associations. A messaging server may include a display component and a messaging component. The display component may be configured to provide a prompt to the first user suggesting that the first user initiate a communication with the one or more other users, the prompt based at least in part on the correlation. The messaging component may be configured to initiate a communication with the one or more other users in response to a selection of the prompt by the first user.

Abstract: A free-standing evaporative air cooling system includes a base, at least one air inlet and at least one cooling pad. A neck extends upwardly relative to the base and includes at least one upwardly-oriented air flow passageway in gaseous communication with the air inlet(s). At least one air outlet is disposed proximate to the upper end of the neck and is in gaseous communication with the air flow passageway.

Abstract: When rich data is tunneled, its associated link identified by a primary data reference is changed by swapping primary references of original data with changed data. Thus, without duplicating the rich data, it is now associated with the changed data, preserving it in constant time. The primary references can include, but are not limited to, names and/or other item identifications. This technique allows preservation of rich data to occur without burdening processing and/or time constraints based on the size and/or number of rich data elements. The technique also allows disparate applications and/or systems to maintain data integrity even when rich data is not expected for a given application and/or system. Since the rich data follows a primary reference, awareness of the rich data is not required for it to be properly handled, ensuring its integrity.
