Abstract: The present invention provides a system and method for retrieving ionospheric parameters from dayside disk-viewing measurements of an ultraviolet emission within the upper atmospheric airglow. The invention may provide nowcasting and forecasting information of the ionosphere, which is important for ultraviolet communications.

Abstract: The present invention comprises a key-fob device including portable remote units with Radio Frequency (RF) receivers or transceivers capable of receiving command transmissions from a high power wireless network and/or RF tower or low power wireless system and/or handheld device. Upon receiving a user's activation signal from the wireless network, the key-fob will then emit an audible sound, activate a flashing light and/or activate various vehicle functions.

Abstract: A boat security system based on two-way paging technology to allow immediate notification of any abnormal situations that the boat owner chooses to monitor. In response to an abnormal condition, affirmative action may be taken such as generating an audible alarm, disabling the boat, or enabling a tracking device. The system communicates alarm condition employing the ReFLEX™ two way paging technology and, when coupled to an alphanumeric pager, allowing for reporting of status conditions of the boat can be obtained. The basic embodiment includes a alarm functions for the bilge including bilge cycles, battery strength, door and hatch sensors, a shock sensor for detecting an impact such as dock line breakage.

Abstract: A dual digital signal processor (DSP) provides real time links between multiple time division channels of a digital carrier system (e.g. T-1) and a host data processor. Operating only on digital signals, internally and at its interfaces to the carrier and host systems, the DSP exchanges data and control signalling information with the carrier system and data and control information with the most processor, converting the data in passage to different digital forms. At the interface to the carrier system, signals are received and transmitted in a form adapted to diverse terminal equipment of users remotely linked to the carrier system via the switched public network. At the host interface, signals are transferred and received in a form suited to the data process requirements of the host system (e.g. data bytes directly representing alphanumeric characters). Thus, the DSP acts as the equivalent of multiple different types of modems in performing required conversions.
