A method for repairing fiber-reinforced composite structures while maintaining original EM and lightning protection using carbon nanotubes, fibers, and thermoset resins is disclosed. According to one embodiment of the invention, the method comprises preparing a damaged area for repair; preparing a repair patch for the damaged area, the repair patch comprising nanotubes; applying the repair patch to the damaged area; and curing the repair patch. A repair patch for a composite structure having a conductive layer is disclosed. According to one embodiment of the present invention, the repair patch includes a binder and nanotubes. A repair resin for repairing a composite structure having a conductive layer is disclosed. According to one embodiment of the present invention, the repair layer includes a resin and nanotubes. A putty for repairing a composite structure having a conductive layer is disclosed. According to one embodiment of the present invention, the putty includes a base and electrically conductive carbon nanotubes.
摘要:
A multi-protocol serial data bus system includes two clock lines and a data line. A controller generates a first clock signal and a first data signal according to a first serial data bus protocol during a first mode of operation of the system, and generates a second clock signal and a second data signal according to a second serial data bus protocol during a second mode of operation. The first clock signal and the first data signal are provided on the first and third signal paths, respectively, during the first mode of operation. The second clock signal and the second data signal are provided on the second and third signal paths, respectively, during the second mode of operation.
摘要:
In an electronic instrument subject to power line interruptions and having a standby power supply, an external timer is used to time a predetermined brief period (e.g. 15 seconds to 1 minute). If the timer has not yet expired when standby power is once again developed, then a controller will cause a real time clock to start timing, using the currently held time of day. If the timer has expired when standby power is once again developed, the controller will cause the time of day clock to indicate that its time is no longer accurate. Moreover, if the timer has expired, then the controller will not cause the receiver to be turned on. If the timer has not expired, then the controller will determine if the receiver was turned on when the AC power line failure occurred, and if so, the controller will cause the receiver to turn on. If the receiver was turned off when the AC power line failure occurred, then the controller will cause the receiver to remain in standby mode. If, however, a reset was caused by an extremely fast phenomenon, such as a kine arc, then the receiver would not have had time to store status bytes. Upon waking up, the receiver would note that it was inoperative for only a short time, and that certain functions, such as degaussing need not be performed.
摘要:
A protective barrier that will typically be installed beneath ceilings during construction work being performed on ceilings or roofs of buildings. The protective barrier can be comprised entirely of one material or of different materials connected by seams. Some or all of these materials can be designed to fail when contacted by water via dissolution, melting or through some other destructive process initiated by contact with water. Some or all of the materials comprising the protective barrier can be designed to fail at a certain temperature. This failure can create access points from the ceiling through the protective barrier to the area being protected by the barrier, which can allow water from a fire suppression system to reach a fire located below the protective barrier.
摘要:
The present protective barrier is similar to those commonly installed beneath ceilings during construction work being performed on ceilings or roofs of buildings, wherein two or more sections are sewn together to construct the protective barrier. However, the present protective barrier also comprises a dustcover, which covers the seam entirely preventing dust from passing through holes created when the seam is sewn using a thread or similar means.

摘要:
Protective barriers are commonly installed beneath ceilings when construction work is performed either on these ceilings or on the roofs located above them. These protective barriers can be comprised entirely of one material or of different materials connected by seams. Some or all of these materials can be designed to fail when subjected to temperatures above a certain temperature range causing melting or some other destructive process to occur to these materials. These failures can create access points from the ceiling through the protective barrier to areas below being protected by the barrier, which can allow water from a fire suppression system, typically located near the ceiling, to reach a fire located below the protective barrier.
摘要:
An electric grill which vaporizes grease and juices and sears the food being cooked. The grill has two sets of heating elements, one located directly beneath the cooking surface and the second located proximate a smoker box. The grease and juices fall from the food located on the cooking surface onto the bottom of the grill which channels the grease and juices into the smoker box. The bottom of the grill also functions as a reflector plate to redirect heat towards the cooking surface. The grease, juices, and, optionally, wood chips may vaporized and smoked by the heating element located proximate the smoker box. A printed circuit board regulates the current passing through the heating elements.
