Abstract: Techniques and materials provide for thermal insulation for tanks, such as tanks for use in space flight missions. Microporous glass blocks may be used as an insulative bridge between spray-on foam insulation and a stainless steel wall of a tank, for example. Blocks of microporous glass may be mechanically attached to the interior of the tank, after which spray-on foam insulation is applied directly to the blocks. The bridging insulation provided by the microporous glass blocks allows the temperature of the stainless steel tank wall to exceed the usable temperature of the spray-on foam insulation by preventing a substantial portion of heat of the stainless steel wall from reaching the spray-on foam insulation. An insulated tank may instead comprise a tank wall that is a honeycomb-structured composite layer including an exterior skin, an interior skin, and a core that presents a relatively long thermal path, for improved thermal insulation.

An example device may include one or more processors and a memory coupled to the one or more processors. The memory includes instructions that, when executed by the one or more processors, cause the device to receive data associated with a modulated optical signal emitted by a transmitter of a first LIDAR device and received by a receiver of a second LIDAR device coupled to a vehicle and the device, generate a rendering of an environment of the vehicle based on information from one or more LIDAR devices coupled to the vehicle, and update the rendering based on the received data. Updating the rendering includes updating an object rendering of an object in the environment of the vehicle.

Abstract: A computing system may operate a LIDAR device to emit and detect light pulses in accordance with a time sequence including standard detection period(s) that establish a nominal detection range for the LIDAR device and extended detection period(s) having durations longer than those of the standard detection period(s). The system may then make a determination that the LIDAR detected return light pulse(s) during extended detection period(s) that correspond to particular emitted light pulse(s). Responsively, the computing system may determine that the detected return light pulse(s) have detection times relative to corresponding emission times of particular emitted light pulse(s) that are indicative of one or more ranges. Given this, the computing system may make a further determination of whether or not the one or more ranges indicate that an object is positioned outside of the nominal detection range, and may then engage in object detection in accordance with the further determination.

Abstract: Disclosed aspects and implementations are directed to systems and techniques for protecting cryptographic operations against side-channel attacks. In one example, polynomials associated with secret data and public data defined on a working domain having a first dimension are mapped to an auxiliary domain having a larger second dimension. The mapped polynomials are masked using masking polynomials associated with a kernel of a homomorphism transformation from the auxiliary domain to the working domain. One or more computations are then performed on the masked polynomials in the auxiliary domain and an output is transformed from the auxiliary domain to the working domain.

Abstract: In a method for optically measuring technical surfaces using a confocal sensor, light is directed onto a sample surface to be measured via an optical system that contains an illumination mask, a sensor matrix, a beam splitter for combining illumination beam and detection beam paths, and imaging optics. The mask has transparent and non-transparent or slightly transparent regions arranged in a checkerboard pattern. The pitch of the mask pattern corresponds to the pixel pitch of the matrix. The mask and the matrix are adjusted relative to each other such that the transparent regions and the pixels of the matrix are simultaneously sharply imaged onto the sample by the imaging optics, whereby the sharp image of the mask is then sharply imaged onto the matrix so that a checkerboard pattern of light and dark illuminated pixels is produced on the matrix. The transparent regions of the mask are round.

Abstract: One example system comprises a LIDAR sensor that rotates about an axis to scan an environment of the LIDAR sensor. The system also comprises one or more cameras that detect external light originating from one or more external light sources. The one or more cameras together provide a plurality of rows of sensing elements. The rows of sensing elements are aligned with the axis of rotation of the LIDAR sensor. The system also comprises a controller that operates the one or more cameras to obtain a sequence of image pixel rows. A first image pixel row in the sequence is indicative of external light detected by a first row of sensing elements during a first exposure time period. A second image pixel row in the sequence is indicative of external light detected by a second row of sensing elements during a second exposure time period.
