摘要:
An improved D.C. power supply for an emergency locator transmitter ELT mounted on an aircraft that does not require lithium batteries but instead uses conventional alkaline batteries in conjunction with a supercapacitor network to provide a reliable power source even when the ELT that is airborne is subjected to extreme cold temperatures that can affect the alkaline battery operation. Alkaline battery pack with a 12 V output is connected to a supercapacitor network board. The supercapacitors are charged when the ELT is activated ON using the comparator network.

摘要:
This invention relates to an emergency locator transmitter (ELT) that transmits an emergency signal to a global navigational satellite system (GNSS) indicating an aircraft crash location, or an aircraft distress tracker event signal that triggers the ELT to provide location of the aircraft, the ELT including a GNSS RF receiver. The invention ELT includes 406 MHz RF signal blanking switch, a GNSS high pass filter, RF radiator and EMI filter protection for the GNSS receiver to protect the GNSS receiver from 406 MHz emergency signals, unintentional RF radiators and electromagnetic interference (EMI) typically found in aircraft.

An external battery pack for protecting against a battery fire or battery explosion, said battery pack connectable to an emergency locator transmitter (ELT) typically mounted in an aircraft. The external replaceable battery pack has a protective metal enclosure and a removable metal cover. The box includes an aluminum honeycomb grid core mesh with passages, each sized to receive a single battery and a pair of printed circuit boards on top and bottom to receive battery power, voltage and current, from multiple batteries for use with an ELT. By using smaller and more batteries together, the possibility of a catastrophic failure is greatly eliminated or reduced in that a smaller battery have a lesser fire or explosion potential. The batteries are isolated from each other from excessive heat or destruction by explosion.
摘要:
A dual-satellite emergency locator beacon and method for programming and updating such emergency locator beacons over the air. The system uses a second commercial satellite as the carrier for the data back to the beacon together with the means of coupling these parts together. The system can be manually updated or can be part of a registration system that gets automatically updated. In a second embodiment a method and apparatus for implementing emergency locator beacon registration is provided. The system provides data concerning the user into a backend service which can be utilized to provide all necessary information needed to register the emergency beacon.

At least one of the plurality of layers in the semiconductor device may be a via layer configured to determine the connections and capacitances of the plurality of individual capacitors in the capacitor array. The semiconductor device may include a metal structure disposed within the device to provide an electromagnetic shield for at least one of the plurality of individual capacitors in the capacitor array.
摘要:
A computer readable medium includes executable instructions to select a panel layout with panels specified in combination. Interactive graphic files representative of input and output values for panels within the panel layout are selected. The interactive graphic files are associated with panels in the panel layout. A composite interactive graphic file representative of input and output values for the interactive graphic files representative of input and output values that have been associated with the panel layout is generated.
摘要:
An apparatus and a method is provided for pushing back caliper pistons, such as for example, single, double or quadruple caliper pistons. The apparatus may be comprised of a first rod, a second rod, and a third rod. The first rod may be connected to the second and third rods so that when the first rod moves the second and third rods also move. The apparatus may also include a first plate, wherein the first rod, the second rod, and the third rod are connected to the first plate. The apparatus may further include a second or press plate which is connected to the second rod and the third rod. The apparatus may further include a third or tube plate and a fourth or wedge plate. The second and third rods may slide through first and second openings of the third and fourth plates.

Method and apparatus for emergency communications using dual satellite communication systems for redundancy and a means of providing additional information to rescue services support emergency response. The system combines the Cospas-Sarsat emergency system for 406 beacons with a secondary means of distress alerting over a commercial satellite system as well as permitting the government agencies responsible for emergency services to directly interface with the person in distress to know about his/her location and to communicate with him or her to resolve the emergency in the best possible way.
