Abstract: A routing method and apparatus are provided. The routing method includes the following steps: sending a probe frame that carries an address of a destination node to a neighboring node(s); receiving a response message returned; selecting one neighboring node from the neighboring node(s) that returns the response message as a next-hop node to which data is sent. A neighboring node with a cost parameter which is lower than a cost parameter in a routing table of the destination node is selected as the next-hop node. In the routing method, when a routing node forwards data, the route is found in real time by broadcasting a probe frame, and data may be sent as long as any one of the neighboring nodes that may arrive at the destination node is in an active state, and thus a data transmission delay is shortened.

Abstract: A method for controlling a power generation system connected to a weak grid may generally include operating a power converter of the system so as to produce current at or above a power factor threshold associated with a power factor operating requirement for the system, detecting that a generator speed of the system has increased over a period of time, detecting that a local reference voltage for the system has decreased within the same period of time over which the generator speed has increased and adjusting the operation of the power converter to produce current at a reduced power factor below the power factor threshold so as to increase a real power output of the system.

Abstract: An origami enabled manufacturing system. The system uses origami design principles to create functional materials, structures, devices and/or systems having an adjustable size and/or shape. An operational device can be coupled to a planar substrate shaped and sized to correspond to a desired origami shape of an origami pattern. A plurality of planar substrates can be coupled together by a plurality of connection members that corresponds to one or more crease of the origami pattern. An array of planar substrates can be formed that convert into a three dimensional structure with origami shape. The resulting three-dimensional structure provides smaller projection area, higher portability and deformability.

Abstract: An arrangement that converts mechanical energy into electrical energy employs a base member and a cantilever member coupled thereto. The cantilever member has two piezoelectric layers with an air space therebetween. A proof mass is coupled to the cantilever member distal from the base member. The first and second piezoelectric layers are formed of lead zirconate titanate (PZT), and the output voltage of the cantilever member is proportional to the height of the air gap. A piezoresistive accelerometer that is useful for measuring mechanical vibration has a suspension beam and a piezoresistive layer be separated from the suspension beam. A method of monitoring an acoustic vibration utilizes a piezoresistive element having an air-spaced cantilever formed of a piezoelectric material in the vicinity of the system to be monitored and obtains an alternating voltage form the air-spaced cantilever of the piezoresistive element.
