  • Patent number: 11054512
    Abstract: The invention relates to a frequency converter circuit for a radar-based distance-measuring device. The core of the frequency converter circuit is a non-linear, high-frequency component, having a frequency connection point and a signal connection point, which serves as a signal input for a low-frequency input signal. On the reception side, the frequency converter circuit comprises at least one receiving antenna for receiving the high-frequency reception signal and a non-linear semiconductor component for downconverting the high-frequency reception signal. The frequency converter circuit therefore uses the effect that, by means of the low-frequency input signal, corresponding harmonic waves are induced at the non-linear, high-frequency component. Furthermore, the high-frequency reception signal is downconverted into a low-frequency evaluation signal, whereby the further determination of the distance can be performed on the basis of the low-frequency evaluation signal, which can be processed more easily.

  • Patent number: 10866306
    Abstract: A radar sensing system for a vehicle includes transmitters, receivers, a memory, and a processor. The transmitters transmit radio signals and the receivers receive reflected radio signals. The processor produces samples by correlating reflected radio signals with time-delayed replicas of transmitted radio signals. The processor stores this information as a first radar data cube (RDC), with information related to signals reflected from objects as a function of time (one of the dimensions) at various distances (a second dimension) for various receivers (a third dimension). The first RDC is processed to compute velocity and angle estimates, which are stored in a second RDC and a third RDC, respectively. One or more memory optimizations are used to increase performance. Before storing the second RDC and the third RDC in an internal/external memory, the second and third RDCs are sparsified to only include the outputs in specific regions of interest.

    Abstract: A shared radar and communication system for a vehicle includes capabilities for radar detection and communication with vehicles equipped with similar systems. The radar system is equipped with pluralities of transmit antennas and pluralities of receive antennas. The radar transmits a signal modulated with spread codes that are information bits. A receiver discriminates the signals sent from own transmitters and multiple reflections to detect objects of interest. In addition, the receiver discriminates signals transmitted from different systems on other vehicles. This requires the receiving system to have knowledge of the codes transmitted by the other vehicle. The receiving system determines the information bits sent by the other vehicle. If multiple radar systems on multiple vehicles use different sets of codes (but known to each other), the multiple systems can create a communication infra-structure in addition to radar detection and imaging.

A risk zone within which the UAV may navigate during the micro scan may include a plurality of virtual tags that identify navigational hazards relevant to the navigation of the UAV at a specific location or specify scan actions to be implemented while the UAV is at the specific location. Scan data from any of a wide variety of sensor types may be compared with profile data using computer vision techniques to identify characteristics, defects, damage, construction materials, and the like. A rule set evaluator may evaluate tags and/or matched profile data to determine adaptive actions to modify the navigation or scanning process of the UAV.

  • Patent number: 9787359
    Abstract: Aspects of the subject disclosure may include, for example, generating first traffic for transmitting along a network path toward a recipient device, determining a schedule for transmitting the first traffic, and facilitating transmission of the first traffic along the network path using a first waveguide system. The first waveguide system has a dielectric coupler, and operates by communicating electromagnetic waves via the dielectric coupler at a physical interface of a transmission medium that propagate without utilizing an electrical return path. The electromagnetic waves are guided by the transmission medium, wherein the electromagnetic waves at least partially surround an outer surface of the transmission medium, and wherein the electromagnetic waves have a non-optical frequency range. Other embodiments are disclosed.

  • Patent number: 9720086
    Abstract: A passive-tracking system is described herein. In one example, the passive-tracking system includes a thermal sensor configured to generate a series of thermal frames based on an object in a monitoring area. In this example, the system also includes a processor and a time-of-flight (ToF) sensor configured to generate a series of modulated-light frames based on the object. The processor may be configured to receive the thermal and modulated-light frames and based at least in part on the data of the frames, generate a novelty representation of the object. Based on this data, the processor may also be configured to determine whether the object is human and if so, generate a three-dimensional (3D) position of the human object. The processor may also be configured to passively track the human object over time by, based on the novelty representation, selectively updating the 3D position of the human object.

  • Patent number: 9467664
    Abstract: A video/audio recording device is mounted on a mobile support for recording surveillance information. The recording device is movable relative to the mobile support to adjustably position the recording device to face the target along a line-of-sight during recording. A database stores public map spaces, private map spaces, and warrant spaces that exist in a geographic area to be surveilled. A programmed controller accesses the database, determines whether the target is recordable from a public map space along the line-of-sight between the recording device and the target and/or whether the target is covered by a warrant space, and controls the recording device to record the surveillance information upon a successful determination that the target is so recordable or so covered.

  • Patent number: 9383438
    Abstract: A presence detection system is equipped with a transmitter that transmits a multipath wireless signal and a receiver that detects the presence of a person by receiving the transmitted wireless signal, within a prescribed space. On the basis of the reception level for a wireless signal received intermittently at the beginning of a first interval, the receiver determines whether there has been a change in the present/absent state of a person. When it is determined that there has been a change in the present/absent state of a person, the receiver determines whether a person is present/absent on the basis of variation in the reception level for a wireless signal received at the beginning of a second interval, which is shorter than the first interval.

  • Patent number: 9282258
    Abstract: Disclosed herein is a method and system for detecting potentially hazardous and/or explosive material concealed under clothing or in luggage. Through the emission, reflection, and reception of microwave radiation, a 3D image of a targeted area can be constructed. The image will show the outline of a moving person as well as any dielectric objects potentially hidden on their body. By measuring phases and amplitudes of microwaves reflected off a dielectric object, the optical path of the microwave through a hidden object can be determined, thus allowing for the creation of a 3D microwave image of a targeted area. Several emitters and receivers can be utilized at once, and video imaging can also be superimposed over the microwave image for improved detection accuracy. The invention has security and safety applications across the nation, particularly in areas of mass transit and large public events.
