A first transceiver edge departs from the joint in a first path in a first direction. A second transceiver edge departs from the joint in a second path in the first direction. Each edge includes at least a first edge sector having a first radius and a second edge sector having a second radius. The radii define a separation between the edge sectors.

Optical in-vivo monitoring systems
InactiveUS20080097221A1Easy to integrateIncrease energy densityDiagnostic recording/measuringSensorsGratingIn vivo
Systems for highly efficient, in-vivo collection of modulated infra-red light are presented. Specifically, these devices are arranged in an important format with a view to integration with a wristwatch or other wearable device. An optical aperture of large surface area, specially distributed in an annular ring, receives radiation having been modulated in a tissue test site by blood flow. Radiation received about the annular aperture is redirected by a blazed grating or similar optical element at near perpendicular angles, into a radially distributed, condensing light pipe array and further toward a common axis. Radiation converges on the axis, thus increasing the energy density of the collected signal, before it is further directed via a conic element to a detector such as a photodiode. In some versions, these highly specialized optical paths may be formed into a single element of inexpensive plastic or other rigid substrate.

Low-odor single element equipment grip
A low odor grip is disclosed for a handle of a hand-held implement such as a sports implement or a manual or electric tool which is essentially free of disagreeable odors, which can be installed and quickly shrunk into a tight vapor resistant grip within a matter of a few minutes rather than requiring extended periods of time, and can be installed without the need for any application of heat or use of special tools, equipment or materials. The present device is therefore easy to install, merely sliding over the handle while in dilated state and then allowed to shrink and set by evaporation of the solvent, and thus can be satisfactorily installed in both fabrication facilities and in the field either as an original or replacement grip. The invention also includes an implement fitted with such grip. Representative implements include sports implements such as golf clubs, tennis racquets, weight bars and fishing poles, as well as tools such as hammers, drills, pliers, shovels, axes, and the like. The grip is preferable made of a swellable elastomeric material, preferably a natural or synthetic rubber. Suitable rubbers include EPDM rubber, neoprene or chlorosulfonate polyethylene (Hypalon(TM)) rubber, of which EPDM rubber is preferred.

Dynamic backup routing of network tunnel paths for local restoration in a packet network
A packet network of interconnected nodes employing dynamic backup routing of a Network Tunnel Path (NTP) allocates an active and backup path to the NTP based upon detection of a network failure. Dynamic backup routing employs local restoration to determine the allocation of, and, in operation, to switch between, a primary / active path and a secondary / backup path. Switching from the active path is based on a backup path determined with iterative shortest-path computations with link weights assigned based on the cost of using a link to backup a given link. Costs may be assigned based on single-link failure or single element (node or link) failure. Link weights are derived by assigning usage costs to links for inclusion in a backup path, and minimizing the costs with respect to a predefined criterion.
