A rental / car-share (RCS) vehicle access and management system and method, in some embodiments, utilizes barcodes, QR codes (or NFC / RFID), GPS, and a mobile app coupled with a wireless network to enable customers to bypass the reservation desk and pickup and drop off reserved RCS vehicles using a mobile phone, tablet or laptop. The QR code, RFID, or NFC communication with the mobile application allows for identification of the vehicle by a mobile application, which, if authorized, can access the vehicle via a temporary access code issued by remote servers. The remote servers and / or mobile application communicates with a control module that plugs into the on-board diagnostics module of the rental / car-share (RCS) vehicle and includes a host processing unit with a processor, an accelerometer, data storage, a GPS with internal GPS antenna; a wireless modem with internal antenna, and CAN bus transceivers connected with the processor, and a USB programmable interface.

A system determines three-dimensional attitude of a moving platform using signals from two closely spaced Global Positioning System (GPS) antennas. The system includes three rate gyroscopes and three accelerometers rigidly mounted in a fixed relationship to the platform to aid in determining the attitude. The system applies signals from one of the two GPS antennas to sufficient channels of a GPS receiver to support navigation. The system applies signals from a second of the two GPS antennas to the additional receive channels to support interferometry. The system resolves the ambiguity normally associated with the interferometric heading solution by having closely spaced GPS antennas, and uses interferometry to refine a coarse heading estimate from a GPS plus Inertial Measurement Unit (IMU) transfer alignment solution. The system achieves sub-meter spacing of the two GPS antennas by merging many temporal interferometric measurements and the attitude memory provided by the IMU time-history solution.

A system for detecting a pedestrian is provided. The system includes a base and a mast extending from the base, and a plurality of sensors mounted on the mast, the plurality of sensors for detecting objects and pedestrians within a predetermined range, and wherein the sensors include a GPS antenna, at least one camera, an alert mechanism, a radio with an integrated directional antenna, and a short range communication antenna. A path predicting circuit is in communication with a system vehicle and the pedestrian detection system. The path predicting circuit processes information from the system vehicle and pedestrian detection system to predict the path of the system vehicle and detected objects. The path predicting circuit is in communication with a path collision circuit and the predicted paths are mapped on the path collision circuit so as to determine if the system vehicle may possibly collide with a detected object.

An apparatus for providing Global Positioning System (GPS) position data to an underwater diver for use in navigation is comprised of a SCUBA Flag / Antenna Float, positioned on the surface of the water, containing a Spring-loaded Cable Reel which is connected via a Signal Umbilical Cable to a GPS Capsule carried by the underwater diver. A GPS Antenna and power supply provide a signal to a GPS Receiver / Display which is encased in the GPS Capsule. The diver views icons displayed on the GPS Receiver to determine his / her current position in relation to previously entered waypoints, or geographical coordinates, such as a wreck, dive boat, or locations of interest plotted by the diver during the dive. The position information displayed by the GPS receiver enables the diver to navigate to and from the various locations or geographical coordinates while submerged.

A wireless portable device that includes a screen, a wireless antenna, transmitter and receiver for communicating over a wireless network with a remote server, a GPS antenna and receiver for receiving GPS signals from GPS satellites, a processor controlling communication over the wireless network and processing the GPS signals, memory storing a navigator application that utilizes the GPS signals and a client program. The client program includes a hypertext markup language (HTML) or scripting language interpreter that is configured to receive a file including hyperlinks from a server, render the file on the screen of the wireless portable device, recognize tags associated with a hyperlink, including either location information, geocode or both, and use the tags to initiate the navigator application.

A RF breathalyzer system, which transmits a unique RF signal in response to a toxic or non-toxic breath sample given to a RF breathalyzer by the user. An immobilizer CPU is installed in a vehicle to receive commands from the RF breathalyzer and to control a horn and lights of a vehicle, to immobilize the engine, and is connected to a GPS antenna driver through a mobile phone / pager unit to communicate with a monitoring station.

A charging system which carries out position confirmation of a moving body at a place where there is a radio wave blocked facility, and which carries out automatic detection of GPS antenna blockage for avoiding charging. The charging system includes a GPS positioning device for recognizing a vehicle position, a vehicle speed pulse measuring device for dead reckoning navigating, a monitor device which generates information expressing a current position by using these, and a charging processing which judges whether or not a recognized current position is within a charge area and which carries out data processing for charging. The monitor includes a simple map database which includes positions of facilities or geographical features at which GPS positioning is impossible, and when GPS positioning is impossible, the facility or geographical feature corresponding to the current position is detected, and that position is made to be a current position.
