  • Redundant power system switch for backup power switching without power interruption
    Patent number: 8378519
    Abstract: A redundant power system may include a first switch that connects between a redundant power source and a first remote system, a second switch that connects between the redundant power source and a second remote system, and a control circuit. The control circuit may apply a first control signal to the first switch to cause the redundant power source to connect through the first switch to the first remote system via a switched connection. The control circuit may determine if the second remote system requires power, and may apply a second control signal to the first switch to open the switched connection when the high priority remote system requires power. The control circuit may apply a third control signal to the second switch, upon an expiration of a delay timer, to cause the redundant power source to connect through the second switch to the second remote system.

  • Voltage monitoring circuit for redundant power systems
    Patent number: 8237310
    Abstract: A redundant power system determines a rate of decline of a voltage supplied by a remote power source. The redundant power system further supplies power from a redundant power source to the remote power source based on the determined rate of decline of the voltage supplied by the remote power source.

  • REDUNDANT POWER SYSTEM SWITCH FOR BACKUP POWER SWITCHING WITHOUT POWER INTERRUPTION
    Publication number: 20110115291
    Abstract: A redundant power system includes a redundant power source, a first switch, a second switch, and a control circuit. The first switch connects between the redundant power source and a low priority remote system, where the first switch has a characteristic of turning off faster than the first switch turns on. The second switch connects between the redundant power source and a high priority remote system, where the second switch has a characteristic of turning off faster than the second switch turns on.

  • Method and apparatus for maximizing data throughput in a packet radio mesh network
    Patent number: 6480497
    Abstract: In a mesh network communication system, net throughput is optimized on the link between the communicating nodes by dynamically modifying signal characteristics of the signals transmitted between nodes in response to performance metrics which have been determined from analysis at the receivers for the corresponding links. The signal characteristics can be the data rate, modulation type, on-air bandwidth, etc. The performance metrics are calculated based on data-link on-air characteristics of received signals.
