This patent concerns a compact and portable system for real-time detection and location of electromagnetic emissions in the spectrum used by mobile devices (cell phones and Wi-Fi/Bluetooth devices). The principle of detection and location is based on phased array technology, which enables the synthesis of a directional radiation beam that can be electrically controlled in terms of both its shape and direction. This technology is used primarily in military and astronomical applications. The device also includes localization and control algorithms. This device will allow for detecting and locating electromagnetic emissions by means of an antenna beam scan within a field of view of 8080 degrees. Once the detection and location have been established, the results are overlaid to a visual image captured by a video camera.

An intraocular micro-display (IOMD) system includes an auxiliary head unit. The auxiliary head unit includes a frame for mounting to a head of a user, a scene camera module mounted in or on the frame in a forward-facing orientation, a gaze tracking module disposed in or on the frame and configured to monitor an eye of the user, and an auxiliary controller. The auxiliary controller includes for: acquiring a scene image with the scene camera module, determining a gazing direction of the eye based upon gaze direction data from the gaze tracking module, identifying a sub-portion of the scene image based upon the gazing direction, and wirelessly relaying the sub-portion of the scene image to an IOMD implant within the eye for displaying to a retina of the eye.

Augmented reality apparatus and methods of use are provided with secure persistent digital content linked to a location coordinates. More specifically, the present method links a physical location with digital content to enable a user interface with augmented reality that combines aspects of the physical area with location specific digital content. According to the present method, digital content remains persistent with a location even if visual aspects of the location change.

A system for determining a location of a work machine operator relative to a work machine comprises a machine controller, a radio frequency receiver, and an infrared transmitter unit. The unit comprises a plurality of infrared transmitters configured to generate infrared signals that collectively divide a 360-degree area around the infrared transmitter unit into a plurality of zones. A remote controller remote from the work machine, which comprises a radio frequency transceiver and an infrared receiver, is configured to receive the infrared signal generated by at least one of the plurality of infrared transmitters. The remote controller has a computer system which is configured to decode information within the one or more infrared signals to determine whether the operator is in an approved zone. The computer system enables the radio frequency transceiver to communicate with the radio frequency receiver upon determining that the operator is in the approved zone.

A system is provided. The system comprises: a processing system comprising a memory coupled to a processor; wherein the processing system is configured to be coupled to at least one sensor; wherein the memory comprises a grid adaptation system, a system model, measurement data, and an estimation system; wherein the measurement data comprises data measured by the at least one sensor; wherein the estimation system is configured to provide probability density functions (PDFs) for a predictive estimate and a filtered estimate of a state in a form of a point-mass density; and wherein the grid adaption system is configured to adapt grid parameters of a predictive estimate and a filtered estimate.

A radio receiver is made much more immune to jamming signals. A vector EM sensor, in a 2-dimensional (3-axis sensor) or 3-dimensional (6-axis sensor) sensor configuration, is combined with a unique digital rotation to a preferred direction to create a new reference channel and, using an advanced frequency domain noise mitigation algorithm or other noise cancellation algorithm, can effectively reject jamming and other interference signals and improve the signal-to-noise ratio (20-40 dB) and the receiving performance of the receiver. The method can cancel both near-field and far-field interference and improve accuracy for various applications concerned with establishing the direction, or bearing, to a source. A communication receiver with the vector sensor and the cancellation algorithm has unique anti-jamming capabilities even for multiple jamming sources.

A system and method for improved detection of lasers for use in laser guidance systems. By providing background illumination via one or more radiation sources the accuracy of the laser detection system can be improved. A closed loop system detects the background current on the detector and provides additional illumination when the back ground level is below a threshold current value thus providing for a faster detector response.
