Abstract: An optical filter may reduce the frequency and/or severity of photophobic responses or for modulating circadian cycles by controlling light exposure to cells in the human eye in certain wavelengths, such as 480 nm and 590 nm, and a visual spectral response of the human eye. The optical filter may disrupt the isomerization of melanopsin in the human eye reducing the availability of the active isoform, whereas the attenuation of light weighted across the action potential spectrum of the active isoform attenuates the phototransduction cascade leading to photophobic responses. Embodiments of an optical filter are described. In one embodiment an optical filter may be configured to transmit less than a first amount of light in certain wavelengths, and to transmit more than a second amount of light weighted across the visual spectral response. Methods of use and methods of manufacturing optical filters are also described.

Abstract: A reconfigurable device comprises flexible bladder that encloses a jammable material. The geometry of the device can be altered by unjamming the jammable material (making it flexible), changing the shape of the device while it is flexible, and then jamming the jammable material (making it rigid). In some applications of this invention, a joint connects rigid arms. The ends of the rigid arms are enclosed in the bladder. By varying the stiffness of the jammable material in the bladder, the stiffness of the joint can be controlled.

Abstract: Improved methods and networks of components are described for dynamically changing an operational mode of node operations in a wireless node network having at least a plurality of master nodes and a server. A method begins with a first master node detecting an environmental change related to the first master node, such as when the first master node loses reception of a location signal due to surrounding structure. In response to the detected environmental change, changing an operational mode for the first master node to a temporary ID node mode where the first master node no longer can self-determine its location. The first master node operating in the temporary ID node mode then notifies the server that the first master nodes is operating in the temporary ID node mode, and associates with a second master node.

Abstract: Embodiments provide methods, apparatuses, and systems for fixation of a fractured bone. In various embodiments, the systems and plates may provide elastic suspension of the receiving holes relative to the osteosynthesis plate. This elastic suspension may promote load distribution between the screws that connect a bone segment to the plate, thereby reducing stress risers and load shielding effect. In addition, stress at the screw holes, and within the construct as a whole, is reduced by incorporation of these elastic elements in the plate. Additionally, in some embodiments, for instance if fracture healing by callus formation is desired, elastic suspension of the receiving holes relative to the osteosynthesis plate may enable small, controlled amounts of relative motion between bone fragments connected by the plate, which may promote fracture healing by callus formation.
