Abstract: Exemplary methods and systems manage a mobile network. A mobile network node is managed when the node is connected to the network. However, an alarm is not necessarily generated when the node is not connected to the network. A status message is periodically generated and transmitted from the mobile network node to a network control facility. The status message may include any status information regarding the mobile network node as desired. When the status message is indicative of a predetermined condition, an alarm is automatically generated. When no status message is received from the mobile network node, a determination is made whether connectivity exists between the mobile network node and the network. If connectivity does not exist between the mobile network node and the network, then no alarm is generated. If connectivity does exist between the mobile network node and the network, then an alarm is generated.

Each VSAT terminal is provided with two separate tuners, one for Unicast information and one for Multicast information. The system thus provides Unicast information through the Unicast channel to the Unicast receiver in the VSAT terminal to individual destination VSAT terminals, and sends Multicast information to all VSAT terminals via the Unicast channel and the Unicast receivers in each VSAT terminal.

Abstract: During a system reconfiguration, a selected column or column of wireless units, such as associated with airplane seats, are powered up. The first unit in the column detects a ground and begins a wireless identification process with an access point which allows the system to determine a corresponding physical location for each node's logical address. The first unit then closes a switch, which connects the ground to the next unit. As the next unit detects the ground on the line, such as a token line, the second unit communicates with the AP. This process continues sequentially down the column until the last unit is assigned a physical location/address. The next column of units can then be powered up and identified.

Abstract: A radio control device is provided that has the D/R function wherein the rate can be switched by a simple operation without impairing the operability of a stick. The adjustment value (rate) determining a relationship between stick operation amount and servo motor operation amount is switched at the changeover point arbitrarily set within a range of stick operation amounts. The rate 1 is 100% while the rate 2 is 60%. The point 1 is set to the position corresponding to about 65% of the maximum value of the stick operation amount in the right direction (or down direction). The point 2 is set to the position corresponding to about 85% of the maximum value of the stick operation amount in the left direction (or up direction). In the rate 2, the rudder does not effectively work over the range where the operation amount of the stick is relatively small. When the adjustment value exceeds the point, the mode enters the rate 1, so that the rudder works effectively.

Abstract: In a clamshell housing, such as is used for portable devices, engaging elements other than screws or hooks are employed to prevent the two halves of a clamshell housing from having significant slippage between them along the interface at which they meet when the clamshell is subjected to bending and/or torsional moments. Such engaging elements may include slip preventing elements at the clamshell halves interface, e.g., various forms of interlocking teeth, elements that increase friction, or the like, which are added to, or molded into, each half of the housing. By restricting relative motion along the plane of the interface, the propensity to separate along the direction perpendicular to the interface plane is reduced. This is achieved because the restriction of the relative motion increases the bending and torsional rigidities.

A terrestrial communication portable unit is detachably mounted in the mobile satellite communication unit. The mobile satellite communication unit as base unit does not include a key operating section, a display section and a speech transducer section having a microphone and a loudspeaker, and utilizes those mechanically assembled on the portable unit side for keying and other operations. In an interlocked relation to the removal of the portable unit, the stand-by state of the base unit is turned off. It is thus possible to avoid wasteful battery power consumption on the base unit side.

Abstract: In a code division switch in a satellite communication system each of a plurality of uplink CDMA modulated RF beams, each including a plurality of uplink traffic channels, are down converted to IF and overspread with a new orthogonal code having a spreading rate N times that of the spreading code of the uplink CDMA modulated RF beam. All of the overspread beams are combined into a single combined IF stream. The individual traffic channels are extracted from the combined IF stream by de-overspreading the stream with orthogonal codes and despreading with beam and traffic channel specific orthogonal codes. All traffic channels are respread with downlink beam codes and downlink orthogonal traffic channel codes and joined onto selected ones of downlink CDMA modulated IF beams having common destinations with the included traffic channels. Downlink CDMA modulated IF beams are up converted to RF frequency and transmitted to selected destinations.

Abstract: An automated transceiver is adapted to monitor a frequency of interest. In response to receiving some predetermined protocol, it becomes activated and records the next transmission on the frequency. The transceiver then rebroadcasts the recorded transmission. In this way, a radio operator can be assured that the transceiver is operating when the rebroadcasted transmission is received. If the transmission from the device is an acceptable quality, there is an assurance that the transceiver is operating properly since, to receive the rebroadcasted transmission, both the transmitter portion must operate to transmit the message to the inventive radio check device, and the receiver portion of the transmitter must be operational to receive the rebroadcasted message from the system. The remote operator need not rely on the subjective determination of another. Further, the participation of another person is not required.

Abstract: An interface circuit which receives a PCM telemetry data stream comprising waveform divided into 100 words including a three word frame sync signal. The PCM data stream is supplied to a comparator which converts input telemetry signal to a TTL compatible signal. When the PCM data is unencrypted, the PCM data stream is supplied to a de-randomizer circuit which de-randomizes the randomized data. A bit sync circuit which also receives the PCM data stream generates a 320 kHz clock signal which is synchronized to the incoming PCM data stream. The de-randomized PCM telemetry data stream which is in a serial format and the 320 kHz clock signal pass through a digital multiplexer to a universal synchronous asynchronous receiver transmitter. When the receiver transmitter detects a PCM frame sync signal for a frame of PCM data, it interrupts a master microprocessor which then retrieves each word of PCM data from the frame. The master microprocessor writes the frame of PCM data into one bank of a dual Port RAM.

Abstract: Simultaneous transmitter operation in a radio network is prevented by monitoring the signal received at the control position from the transmitter of the apparatus, this signal being delayed by the passage down land lines connecting the control position to its transmission antenna and the receiver to its control position. If a signal is received within a known time period from the time of commencement of a transmit action then it is assumed to be a signal from a remote transmitter and the operation of the local transmitter is aborted to prevent interference. The system is particularly useful where land lines and consequent time delays are present between the control position and the transmitter and the receiver and the control position.

Abstract: A system of making satellite-to-ground range measurements, carrying out communications between a ground station and a constellation of autonavigating satellites, and using these range measurements to improve navigation accuracy is disclosed.

Abstract: Generation of a high power rf pulse is achieved in a simple transmitting device that uses permanent magnet material(s) to store energy. Such energy is released through the thermal quenching of the magnetic material(s). Thermal quenching is accomplished, e.g., through an explosion. Such thermal quenching is facilitated in one embodiment by using a magnetic composite material comprising both magnetic particles and explosive particles. The rf pulse thus generated may be used for any desired purpose, e.g., tracking or research. The transmitting device includes a permanent magnet for establishing a constant magnetic flux for so long as the magnet retains its normal magnetic properties. The magnetic flux passes through a coil. Upon the thermal quenching of the magnetic material(s), the magnetic properties rapidly change, causing the magnetic flux to also rapidly change, thus inducing a high power electrical pulse in the coil.
