Scanners, targets, and methods for surveying

Abstract: Apparatus and methods useful in surveying to provide information rich models. In particular, information not readily or possibly provided by conventional survey techniques can be provided. In some versions targets provide reference for baseline positioning or improving position information otherwise acquired. Scanning may be carried out in multiple locations and merged to form a single image. Machine mounted and hand mounted scanning apparatus is disclosed.

Systems, apparatus, and methods for acquisition and use of image data

Abstract: Systems and methods for mapping. In one version mapping can be carried out. Vehicles may carry scanners used for mapping and three-dimensional modeling. Surveillance and monitoring methods and apparatus are also disclosed.

Systems, apparatus, and methods for data acquisition and imaging

Abstract: A scanning system uses synthetic aperture radar and photography. The system is capable of conjoint use of image data developed by these and other scanning apparatus to form a model of a zone. In some versions, the model includes subsurface image information. Methods for use to scan and for implementation of images and models developed by the scan are also disclosed.

Mapping Techniques Using Probe Vehicles

Abstract: Vehicle-mounted device includes an inertial measurement unit (IMU) having at least one accelerometer or gyroscope, a GPS receiver, a camera positioned to obtain unobstructed images of an area exterior of the vehicle and a control system coupled to these components. The control system re-calibrates each accelerometer or gyroscope using signals obtained by the GPS receiver, and derives information about objects in the images obtained by the camera and location of the objects based on data from the IMU and GPS receiver. A communication system communicates the information derived by the control system to a location separate and apart from the vehicle. The control system includes a processor that provides a location of the camera and a direction in which the camera is imaging based on data from the IMU corrected based on data from the GPS receiver, for use in creating the map database.

Systems and methods for computer assisted operation

Abstract: An augmented reality method includes selecting an image of an object to be installed; converting the image into a 3D model; capturing a view of an environment and selecting a place to insert the 3D model; overlaying the 3D model with the view of the environment in a mashed-up and aligned manner wherein the 3D model view is displayed contemporaneously and contiguously to form an augmented reality view; and enabling user interaction with the displayed 3D model view to update the 3D model of the environment in the 3D modeling system.

Radar-based gesture sensing and data transmission

Abstract: This document describes techniques and devices for radar-based gesture sensing and data transmission. The techniques enable, through a radar system, seamless and intuitive control of, and data transmission between, computing devices. This radar system can both transmit data and sense gestures, thereby performing with a single system, control of many devices and data transmission with those devices. Not only can this provide control of many devices, from refrigerators to laptops, this radar system also allows high-bandwidth data transmission between devices.

Radar-enabled sensor fusion

Abstract: This document describes apparatuses and techniques for radar-enabled sensor fusion. In some aspects, a radar field is provided and reflection signals that correspond to a target in the radar field are received. The reflection signals are transformed to provide radar data, from which a radar feature indicating a physical characteristic of the target is extracted. Based on the radar features, a sensor is activated to provide supplemental sensor data associated with the physical characteristic. The radar feature is then augmented with the supplemental sensor data to enhance the radar feature, such as by increasing an accuracy or resolution of the radar feature. By so doing, performance of sensor-based applications, which rely on the enhanced radar features, can be improved.

Remote vehicle rental systems and methods

Abstract: A system for renting vehicles is disclosed. The system can comprise a vehicle access communicator (“VAC”) capable of interfacing with one or more functions of a rental vehicle and a user provided portable electronic device. The VAC can control various functions of the vehicle including, but not limited to, the door locks and/or enabling/disabling the vehicle. The VAC can also monitor various functions of the vehicle including, but not limited to, the fuel level and/or the odometer readings. The VAC can connect to the portable electronic device using a suitable connection method to access additional functionality such as, for example and not limitation, locations services, cellular, and/or internet access. The VAC and the portable electronic device can be used to provide a rental system with reduced infrastructure and operating costs. The system can enable the use of “Green Zones” to provide permanent or temporary vehicle rental areas.
