Abstract: Systems and methods are disclosed with respect to using a blockchain for managing the subrogation claim process related to a vehicle collision, in particular, utilizing evidence oracles as part of the subrogation process. An exemplary embodiment includes receiving recorded data from one or more connected devices at a geographic location; analyzing the recorded data, wherein analyzing the recorded data includes determining that an collision has occurred involving one or more vehicles; generating a transaction including the data indicative of the collision based upon the analysis; and transmitting the transaction to at least one other participant in the distributed ledger network.

Abstract: A window insertable pet door devised for removable installation in a window without tools and without altering the window by including a center frame having a U-shaped bracket on a top side thereof and a pair of side panels that slidingly extend from the center frame to engage a bottom railing and a respective one of a right railing and a left railing of a window frame. Each side panel includes an outer trim and a static barrier wall therewithin formed of a plurality of vertical popoid pleats. An annular door frame is centrally disposed in the center frame, with a gasket being disposed between the door frame and the center frame. A plurality of pliable triangular flaps, radially disposed within the door frame, converge at a center point of the door frame to simultaneously fold inwardly and outwardly for passage of a cat therethrough.

Abstract: A standard handheld cellular telephone for obtaining diagnostic data is described. In at least one aspect, a standard handheld cellular telephone has a processor, a cellular transceiver, a signal transmitter, a signal receiver and memory for storing instructions for execution by the processor. The acoustic, electromagnetic, optical, and positioning functions of a cellular telephone are exploited. The standard handheld cellular telephone is configured to be capable of performing operations including causing the signal transmitter to transmit a signal through a medium when the signal transmitter is placed adjacent to the medium, receiving with the signal receiver one or more propagations of the transmitted signal after the transmitted signal has passed at least in part through the medium, and obtaining diagnostic data from the received one or more signal propagations.

Abstract: Embodiments include an underwater communications device and methods of using and operating such devices. For example, an underwater communications device may include a radiative element, a communications section comprising at least one of a receiver and a transmitter. The radiative element communicates RF signals associated with the communications module. The system further includes an at least partially nonmetallic housing to enclose the radiative element and the communications section.

Abstract: A new and improved low power GPS signal receiver system includes a GPS signal receiver device and control processor for powering up the signal receiver device for a first sufficient period of time to locate and acquire a time signal from a single GPS satellite and then powering down the GPS signal receiver device after establishing a local time and for waiting another sufficient period of time after receiving a user request to update time before powering up the signal receiver device to facilitate about an immediate sync on another GPS navigation message subframe indicative of the time maintained by said single GPS satellite vehicle. Once the second sufficient period of time has elapsed, the control processor powers up the GPS signal receiver device for a third sufficient period of time to acquire and process 29 bits of subframe message information indicative of time maintained by the GPS satellite vehicle.

Abstract: There is disclosed a portable free drifting oceanographic instrument package for cyclically collecting oceanic and/or fresh water environmental data over a range of depths.
