Abstract: A band configured to wrap around and be secured to an object includes at least three members pivotably connected to one another so as to be pivotable between an open position and a closed position, the first member including an outwardly disposed face defining an imaginary plane and each of the second and third members including an actuator prong that extends outwardly beyond the imaginary plane when in the open position and that is retracted to no longer extend outwardly beyond the imaginary plane when in the closed position. Movement of the object into contact with the first member so as to exert actuation forces toward the outwardly disposed face when the actuator prongs are in contact with a surface causes the second and third members to move from the open position to the closed position due to forces created between the actuator prongs and the surface.

Abstract: An injection mold for the manufacture of an axisymmetric part of composite material comprising a mandrel supporting a fibrous preform and comprising an annular wall, and a plurality of counter-mold angular sectors assembled to the mandrel and intended to close the mold and to compact the fibrous preform wound on the mandrel. Each angular sector comprises an annular base intended to come into contact with the fibrous preform. The plurality of angular sectors includes a first series of angular sectors and a second series of angular sectors, first and second lateral edges of the first series of sectors each including a protruding lower portion, the first and the second lateral edges of the second series of sectors each including a recessed lower portion.

Abstract: A band has at least one actuator including first and second members connected to one another so as to be pivotable between open and closed positions. The first member includes a pair of deformable beams, each having a protuberance extending therefrom. The second member includes a series of ridges and valleys formed therein that are sized, shaped and positioned to cooperate with the protuberances extending from the beams. In the open position and the closed position, the protuberances align with the valleys, such that the beams are in a relaxed state and generally parallel with each other, and when the first and second members are pivoted to positions between the open and closed positions, the protuberances cooperate with the ridges, such that the beams are elastically deformed so as to no longer be parallel with each other, and so as to store strain energy.

Abstract: Systems, devices, and methods for determining an optimal position for a physiological sensor against a subject are described herein. A system may include a physiological sensor and a processing device. The processing device may store and execute instructions to receive a first signal generated by the physiological sensor as the physiological sensor is at a first position relative to the body part, receive a second signal generated by the physiological sensor as the physiological sensor is at a second position relative to the body part, determine a difference between the first signal and the second signal, determine, based on the difference, whether the first position or the second position is more closely aligned to a vein or an artery of the subject; and generate an indicator that indicates whether the first position or the second position is more closely aligned to the vein or the artery.

Abstract: A band includes a pair of members moveable between an open position adapted to receive an article in a channel and a closed position adapted to retain the article within the channel. Each of the members includes a plurality of pivotally attached bistable compliant links, such that when the links are pivoted past a threshold position toward the closed position, the links are biased toward the closed position and such that when the links are pivoted past the threshold position toward the open position, the links are biased toward the open position. An actuator linkage is pivotally connected to at least one of the links, the actuator linkage including an engagement end protruding into the channel when the members are in the open position, such that movement of the article into the channel causes the article to contact and exert actuation forces on the engagement end.

Abstract: Embodiments disclosed are systems and methods for interfacing a metallic capillary in a microchannel of a metallic body. A method may include inserting a portion of the metallic capillary into a portion the microchannel of the metallic body, sintering the portion of the metallic capillary to the portion of the microchannel of the metallic body, disposing a sacrificial powder at least proximate to the metallic capillary and the metallic body after sintering the portion of the metallic capillary and the portion of the microchannel of the metallic body, and infiltrating at least the portion of the metallic capillary sintered to the portion of the microchannel of the metallic body with an infiltrant in the presence of the sacrificial powder disposed at least proximate to the metallic capillary and the metallic body.

Abstract: A plurality of bistable compliant links are pivotally attached to one another, each of the links having a compliant section and first and second rigid sections extending from the compliant section. The links are pivotally attached to one another via the first and second rigid sections, such that when the links are pivoted with respect to each other past a threshold position toward a closed position, the links are biased toward the closed position by forces created by the compliant sections, and when the links are pivoted with respect to each other past the threshold position toward an open position, the links are biased toward the open position by forces created by the compliant sections. The forces created by the compliant sections biasing the links toward the closed position and biasing the links toward the open position are caused by elastic deformation of the compliant sections.

Abstract: A band includes at least three members pivotably connected to one another so as to be pivotable between open and closed positions. A first member includes first and second permanent magnets disposed at opposite ends thereof, a second member includes a third permanent magnet and a third member includes a fourth permanent magnet. The first and second members are configured such that when they are pivoted with respect to each other past a threshold position toward the closed position, they are biased toward the closed position by forces created by the first and third magnets and when they are pivoted with respect to each other past the threshold position toward the open position, they are biased toward the open position by forces created by the first and third magnets. The first and third members are similarly biased by forces created by the second and fourth magnets.

Abstract: An ingestible device (200), comprising: a housing (210, 220) comprising a stop geometry (228) at an exit hole (224); a tissue penetrating member (230) and an actuator that comprises: a pushing portion (260) configured for axial movement from a first to a second position, the pushing portion configured to move the tissue penetrating member from within the housing to a lodged position in tissue, and a holder portion (270) coupled with the pushing portion (260) for initial axial movement with the pushing portion. In the first position the holder portion releasably holds the tissue penetrating member (230) in axial retaining engagement. As the pushing portion (260) moves towards the second position, the tissue penetrating member (230) moves through the exit hole (224) until the holder portion (270) enters into engagement with the stop geometry (228). The pushing portion (260) moves further to release and advance the tissue penetrating member (230).
