  • Patent number: 10775507
    Abstract: An electro-optical device includes a laser, which is configured to emit toward a scene pulses of optical radiation. An array of detectors are configured to receive the optical radiation that is reflected from points in the scene and to output signals indicative of respective times of arrival of the received radiation. A controller is coupled to drive the laser to emit a sequence of pulses of the optical radiation toward each of a plurality of points in the scene and to find respective times of flight for the points responsively to the output signals, while controlling a power of the pulses emitted by the laser by counting a number of the detectors outputting the signals in response to each pulse, and reducing the power of a subsequent pulse in the sequence when the number is greater than a predefined threshold.

  • Patent number: 10775508
    Abstract: A compact remote sensing device is described that includes a transmit component that scans a beam of light across a scene or object field, and a receive component that receives return light from the object field. The transmit component includes a small, fast scanning mechanism such as a MEMS mirror or a piezo mirror that scans a beam of light emitted by a light source across a field of view (FOV). The receive component includes a focal plane array (FPA) with a FOV at least large enough to capture the FOV of the scanning mechanism. The FPA may be a low resolution FPA (i.e., with fewer pixels than the resolution of the scanning mechanism), and the light beam may be scanned and captured at multiple spots within the pixels of the FPA.

  • Patent number: 10765404
    Abstract: An internal probe device for insertion into the body of a patient, comprises an elongate body with a plurality of EAP actuators mounted at the surface of the body. The EAP actuators are made to vibrate so that their position becomes visible in a Doppler ultrasound image. The use of EAP actuators to provide vibrations enables individual locations to be identified. In particular, the movement of the EAP actuator may be largely isolated from the main body of the probe. Furthermore, EAP actuators can be thin, lightweight and have a small form factor suitable for application to or within the surface of a probe, such as a catheter, needle or endoscope.

  • Patent number: 10768281
    Abstract: A time delay of arrival (TDOA) between a time that a light pulse was emitted to a time that a pulse reflected off an object was received at a light sensor may be determined for saturated signals by using an edge of the saturated signal, rather than a peak of the signal, for the TDOA calculation. The edge of the saturated signal may be accurately estimated by fitting a first polynomial curve to data points of the saturated signal, defining an intermediate magnitude threshold based on the polynomial curve, fitting a second polynomial curve to data points near an intersection of the first polynomial curve and the intermediate threshold, and identifying an intersection of the second polynomial curve and the intermediate threshold as the rising edge of the saturated signal.

  • Patent number: 10725174
    Abstract: Methods and systems for estimating a distance between an acoustic sensor and an acoustic reflector in a conduit are disclosed. One such method includes using the acoustic sensor to measure a combined acoustic signal that comprises an originating acoustic signal propagating along the conduit and an echo signal. The echo signal is generated by the originating acoustic signal reflecting off the acoustic reflector after propagating past the acoustic sensor. A frequency domain representation of the combined acoustic signal is determined and the echo signal is identified by identifying in the frequency domain representation periodic oscillations having a peak-to-peak difference between 0.75 Hz and 1500 Hz. The distance between the acoustic sensor and the acoustic reflector is determined from the velocity of the echo signal and a time required for the echo signal to propagate between the acoustic sensor and the acoustic reflector.
