Method for mobile ad-hoc network (manet) multi-hop routing in a broadcast domain
A method for use in a first layer-3 switch, the method comprising: learning, by the first layer-3 switch, a first layer-3/layer-2 (L3/L2) cache, the learning of the first L3/L2 cache including generating a first cache entry that maps a layer-3 address of a first device to a layer-2 address of the first device, the first device being part of a first LAN portion; and transmitting, over a wireless network, contents of the first L3/L2 cache to a second layer-3 switch, the transmitted contents including at least a portion of the first cache entry, the second layer-3 switch being part a second LAN portion, the second LAN portion being connected to the first LAN portion via the wireless network.
A shock isolator includes slots in inner and outer parts that define flexures between the parts. The slots may include inner slots and outer slots that are offset from each other around a perimeter of the inner part. The shock isolator also includes stops that provide a mechanical limit on the movement of the flexures. The stops may be posts that extend from one of the parts into holes in the other of the parts. In another embodiment that stops may be extensions from one of the parts over portions of the other of the parts. The stops help in preventing plastic bending and/or fracture of the flexures due to stress.

A dispersive optical element includes a substrate including a dielectric material, an optical coating arranged on the substrate, and a layer of material including a microscale feature arranged directly on the optical coating.
A system including: a container that is arranged to enclose, at least in part, an object; a monitoring device that is disposed inside or on an exterior surface of the container and configured to monitor the object; a notification device that is coupled to the container, the notification device including: (1) an output unit that is arranged to provide a first indicator and a second indicator, (2) a memory that is configured to store a first threshold, and (3) a processing circuitry that is configured to: establish a connection with the monitoring device; receive a first parameter value from the monitoring device, the first parameter value corresponding to a parameter of the object that is monitored by the monitoring device; detect, based on the first parameter value, whether the parameter has crossed the first threshold; and turn on the first indicator when the first threshold is crossed.
The present disclosure relates to an optical sensor protection system. The system may have a sensor for receiving an incoming optical signal, a passive sensing and modulation component, and an active sensing and modulation subsystem. The passive sensing and modulation component is configured to sense when a first characteristic is associated with the incoming optical signal is present that adversely affects operation of the sensor, and redirects at least a portion of the incoming optical signal thereof away from the sensor to thus reduce an intensity of the incoming optical signal reaching the sensor. The sensor is located on an image plane downstream of the ISM subsystem, relative to a path of travel of the incoming optical signal. The active sensing and modulation subsystem has an active modulation component and is located upstream of the passive sensing and modulation component, relative to the path of travel of the incoming optical signal, and is also located on a conjugate image plane, and is configured to use the redirected portion of the incoming optical signal as feedback in controlling a modification of the incoming optical signal to reduce a risk of damage to the passive sensing and modulation component.
Discussed herein are devices, systems, and methods for determining an approximation of a set of largest maximal cliques containing each node, entities represented by nodes and pairwise relation represented by edges. The method can include receiving dynamic graph data indicating the nodes and the edges of a dynamic graph, estimating, for one or more nodes of the nodes, cliques of size less than (or equal to) a user specified or default clique size parameter, storing the estimated cliques in a clique variable, identifying, for cliques of size greater than (or equal to) the clique size parameter, at most a single clique of a corresponding size, storing the identified single clique in the clique variable, and returning, for each node, the largest maximal cliques in the clique variable.

At least one of the n sections is bent in at least one plane different from the plane of first section, and the first section and n sections each have at least two sides that are broader than at least two other sides; and n−1 walls within waveguide configured to divide a height of first section into n heights. Each of n sections has a height equal to one of the n heights, wherein the n−1 walls are located at a junction of the first section and the n sections and extend toward the first opening of the first section.
A method of embedding a screen in a substrate includes placing the screen on the substrate, and then melting part of the substrate, so that the screen becomes embedded in the substrate. The melting may involve heating at least part of the screen to melt part of the substrate, or directly heating the part of the substrate. The screen may be a screen of electrically-conductive material, and the heating may be Joule heating in which an electrical current is passed through the screen to heat the screen. Alternatively, the heating may involve microwave, conductive, or laser heating. The produced device of the substrate with an embedded screen may be an optical window with an embedded electromagnetic interference (EMI) screen, may be a touch screen or touch display, or may be a window with an embedded heating element, to give a few non-limiting examples.
