  • Patent number: 11917258
    Abstract: Systems and methods are provided for enhanced ship-based network connectivity using a content delivery network (CDN) edge server. An example method includes receiving user requests from user devices in wireless communication with a system, with the user requests being associated with applications executing on the user devices. An operating status associated with a satellite communication system is determined, the operation status being indicative of the satellite communication system having bandwidth and/or connectivity to route the user requests via a satellite network. Based on the operating status being negative, a first subset of the user requests is queued for transmission. A second subset of the user requests are responded to using an edge cache. Based on the operating status being positive, the user requests are transmitted via the satellite network to a shore-based system, the shore-based system routing the user requests to web applications associated with different functionality.

  • Patent number: 11908554
    Abstract: Ultra-Wideband (UWB) wireless technology transmits digital data as modulated coded impulses over a very wide frequency spectrum with very low power over a short distance. To support extended operation, particularly with battery power sources, the inventors have established UWB devices which support wake-up from deep sleep modes when these devices exploit low frequency clock sources for ultra-low power consumption. Further, power consumption may be reduced by exploiting transistors or so-called compounded MOSFET structures whose effective gain and output resistance exceeds any single transistor irrespective of length or by employing biasless low power differential (exponential) transconductance stages within operational transconductance amplifiers in order to provide very high gain low power amplification stages. Further, the inventors have established voltage reference sources that consume very low current, a few nA, and ultra-low power low dropout regulators.
