摘要： 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.

摘要： 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.
