Abstract: Provided herein is a computing system including a processor in communication with at least one memory. The processor is configured to (i) build a model using historical vehicle telematics data and historical vehicle data, the model configured to: (a) predict an operating cost of a vehicle based upon a vehicle type and user data and (b) output operational parameters for operating the vehicle, (ii) receive a vehicle acquisition request for a selected vehicle including vehicle data for the selected vehicle and selected user data for the user of the selected vehicle, (iii) input the vehicle acquisition request data into the model, and (iv) output from the model an acquisition cost and operational parameters for the selected vehicle and the selected user including a procurement cost for the selected vehicle and an operating cost for operating the selected vehicle within the operational parameters for a predetermined time period.

Abstract: A novel syringe is provided herein. It includes a cylindrical barrel having a closed forward end provided with a longitudinally-extending channel therethrough. A hypodermic needle is slidably received in the channel. A frangible septum is disposed in the channel and is adapted to be pierced upon inward sliding movement of the hypodermic needle. At least a single stopper is slidably and sealingly disposed in the barrel to divide the barrel into (i) a forward, payload chamber, defined between the closed forward end of the barrel and the leading face of the stopper, and (ii) a rearward propulsion chamber downstream of the trailing face of the stopper. The propulsion chamber is controllably variably prechargeable to a predetermined gaseous pressure. The syringe may be used with a novel retractable collar and with a novel sliding fin assembly.
