摘要： A system for generating a non-visual notification of a machine condition includes a machine condition sensor configured to sense a machine condition. A notification generation controller is in communication with the machine condition sensor. The notification generation controller generates a notification according to the sensed machine condition. In a feedback configuration the notification generation controller compares an integral of a rate of change of the sensed machine condition with a threshold to trigger the generation of a notification. In a guidance configuration the notification generation controller uses the deviation of the machine condition from a guidance direction determined with a steering algorithm to control the generation of a notification. A non-visual notification generator is in communication with the notification generation controller and generates a non-visual notification based on the notification.

摘要： A high altitude balloon system includes a dual chamber balloon extending from an upper apex to a lower apex with a circumferential edge between the upper and lower apexes. A deflectable diaphragm is within the dual chamber balloon and coupled along the circumferential edge. The deflectable membrane divides the dual chamber balloon into a lift gas chamber formed by an interior surface of the dual chamber balloon and the deflectable diaphragm, and a ballast chamber formed by the interior surface of the dual chamber balloon and the deflectable diaphragm. Optionally, the dual chamber balloon is constructed by interposing the deflectable diaphragm between an upper and lower balloon panels. Each of the upper and lower balloon panels and the deflectable diaphragm are then coupled together along the circumferential edge to form both the lift gas chamber and the ballast chamber.

摘要： A fiber optic GPS signal device and method comprising a VCSEL multimode transmitter having a gain that, together with the GPS antenna gain, is greater than the VCSEL multimode transmitter noise. When in operative communication, via a long length of multimode fiber, i.e., up to 2000 feet and greater, with a fiber optic receiver, the GPS signals are transmitted at, inter alia, L1 and L2 frequencies with minimal degradation over the length of multimode fiber. The present invention may be used in a variety of GPS transmission applications requiring long lengths of cabling. For example, the invention is particularly useful when the GPS antenna is located on top of an office building or cell phone tower and remotely from the GPS receiver and for use in high-volume commercial telephone synchronizing (DTMF) applications.

摘要： A modular device, system and associated method, used to enhance the quality and output speed of any generic GPS engine is provided. The modular device comprises an inertial subsystem based on a solid state gyroscope having a plurality of accelerometers and a plurality of angular rate sensors designed to measure linear acceleration and rotation rates around a plurality of axes. The modular inertial device may be placed in the data stream between a standard GPS receiver and a guidance device to enhance the accuracy and increase the frequency of positional solutions. Thus, the modular inertial device accepts standard GPS NMEA input messages from the source GPS receiver, corrects and enhances the GPS data using computed internal roll and pitch information, and produces an improved, more accurate, NMEA format GPS output at preferably 2 times the positional solution rate using GPS alone. The positional solution frequency using the present invention may increase to as much as 5 times that obtained using GPS alone. Moreover, the modular inertial device may assist when the GPS signal is lost for various reasons. If used without GPS, the modular inertial device may be used to define, and adjust, a vehicle's orientation on a relative basis. The modular inertial device and architecturally partitioned system incorporated into an existing GPS system may be applied to navigation generally, including high-precision land-based vehicle positioning, aerial photography, crop dusting, and sonar depth mapping to name a few applications.

摘要： A technology platform includes hardware and software components that enable applications of autonomous agricultural equipment operation in an agricultural or other off-road setting, within a common architecture. The technology platform represents a technology stack that is a modular architecture leveraged across multiple use cases and vehicle types. The technology platform includes a vehicle interface component for the physical interface to agricultural equipment, a telematics component that provides stable in-field communications between all aspects of the technology platform, and a perception component that operates as a safety mechanism and includes object detection and classification. Additionally, a cloud-side application performs account management and field setup and as well as syncing of field equipment and operating systems in a common operating system. The technology platform includes an executive control layer that enables porting from one platform to another, so software applications in the integrated technology platform work with hardware of any manufacture.

摘要： Techniques for multi-modal contextualization of object detection for use with an agricultural vehicle are described herein. The techniques can provide additional context information to radar detection to assess the likelihood of an object detected by radar of being an object of interest. Examples of detection that might be detected by a radar sensor that, based on the additional context information, the agricultural vehicle can make a determination to ignore can include ground targets, ghost targets, side or overhead reflections from obstacles, detections from tall crops/weeds in a field.
