摘要:
A wireless hub uses a first processor to communicate with IEDs, uses a second processor to communicate with landline SCADA devices, and uses a third processor to extract, store and exchange messages between SCADA protocols and IED data formats so as to as to permit two way communications between SCADA users and IEDs which are independent of protocol data formats and time of exchange.
摘要:
Apparatus for viewing in neutrino light first uses microwaves to create neutrino force differentials on piezoelectric material. The force differentials are used by elements of a matrix to create pixels of a two dimensional picture for use in viewing of underground structures from a satellite. In another form pixels are formed on an LCD display for direct human viewing.
摘要:
In an independent basic service set (IBSS) of IEDs, using wireless communications devices to provide license-free two-way wireless peer to peer communications of digital data between pairs of IEDs, and also to provide wireless peer to peer communications between ones of said IEDs and a common access port to the IBSS.
摘要:
A terminator for permanent connection to either end of a fiber optic cable which then provides transmission of electrical TTL logic signals from one end to the other.
摘要:
A microcontroller-based tap-changer controller including apparatus for keeping track of an electrically closed tap position and for automatically changing the tap setting of load tap-changing transformers and regulators; the tap-changer controller further utilizes the "keep-track" tap position to calculate the source voltage of the regulator for reverse power operations; and, a method for paralleling tap-changing transformers and regulators utilizing the circulating current of the units.
摘要:
A system and method for removing energy from tornados and hurricanes whereby the formation of a tornado is prevented or the force of the tornado or hurricane is substantially decreased. The system comprises superconducting donuts not requiring cryogenic cooling for producing magnetic fields, high permeability posts mounted on the ground in positions at the center of the donuts for developing artificial lightning that can be directed toward the tornado or adjacent clouds to remove energy from the tornado or hurricane.
摘要:
A method and apparatus for forming an antenna extending downwardly into the ground, below the Earth's surface, for sensing the Earth's inner ELF (extremely low frequency) signals which signals are in turn useful in predicting earthquakes and volcanoes, and also sensing the intensity of said phenomena. More particularly, the inventive antenna is basically reversed in direction from conventional antennas.
摘要:
Intrinsically compressed device coded data is sent in radio packets with end use programs expanding the coded data for other purposes. Intelligent electronic devices are physically combined with radio communication mean to avert the coupling of interfering electromagnetic transients into the system processing and sending the data.
摘要:
An extruder die apparatus, system and method for the extrusion of a thermoplastic material, which die apparatus has an adjustable choke ring. The apparatus comprises an extruder housing having an axial bore for the extrusion of thermoplastic material therethrough from the inlet to the outlet of the bore, an inner die lip and an outer die lip about the bore and within the housing, the lips forming a concentric die gap passageway for the extrusion of a thermoplastic material from the one to the other end of the die, and a choke gap within said thermoplastic material flow passageway having a movably positioned choke ring. The choke ring has a plurality of individual, axially extending castellations thereon, some having oval receiving holes therein. These separate, castellated sections may be adjusted incrementally and independently by a plurality of eccentric bolts extending through the housing and the oval receiving holes, to provide selected areas within the choke gap having a restricted cross section thermoplastic material flow area. The restricted choke gap provides for an improved distribution of the thermoplastic material being extruded through the choke gap prior to being extruded through the die gap.
