An attachment housing is for fastening to an exterior side of an aircraft. The attachment housing has a functional compartment. The functional compartment is divided in two, and has a ventilation compartment and a protective compartment. A surrounding wall is configured to separate the ventilation compartment from an environment. The surrounding wall has at least one ventilation opening for air exchange between the ventilation compartment and the environment. A dividing wall is arranged between the ventilation compartment and the protective compartment. The dividing wall has at least one passage opening for air exchange between the ventilation compartment and the protective compartment. The passage opening is configured to counter act a penetration of water, moisture, or particles into the protective compartment.

An object sensing apparatus including: an object sensor mounted at a front upper portion of a vehicle; a vertical-tilting mechanism to allow the object sensor to tilt around a horizontal axis; and a horizontal-rotating mechanism to allow the object sensor to rotate around a vertical axis.

A sensor-cluster apparatus, in which a sensor configured to detect and collect external environment information is mounted in a case. The sensor-cluster apparatus includes a body member on which one kind or more of sensors are mounted on one surface thereof, a case in which an inner space is provided, and one surface thereof is opened to define an opening and on which the body member is mounted so that each of the sensors is exposed to the opening, and a position control device mounted inside the case to adjust a mounting position or a mounting angle of the body member.

Systems and methods for providing wide field-of-view radar arrays. Quadrature phase-shift keying (QPSK) beam forming reduces side lobes by applying a phase shift to transmitted signals to selected transmitting antennas. Super-hemispherical radar coverage at high gain in both broadside and end-fire directions is provided by beam directing elements mounted to a printed circuit board.

The technology relates to enhancing the operation of autonomous vehicles. Extendible sensors are deployed based on detected or predicted conditions around a vehicle while operating in a self-driving mode. When not needed, the sensors are fully retracted into the vehicle to reduce drag and increase fuel economy. When the onboard system determines that there is a need for a deployable sensor, such as to enhance the field of view of the perception system, the sensor is extended in a predetermined manner. The deployment may depend on one or more operating conditions and/or particular driving scenarios. These and other sensors of the vehicle may be protected with a rugged housing, for instance to protect against damage from the elements. And in other situations, deployable foils may extend from the vehicle's chassis to increase drag and enhance braking. This may be helpful for large trucks in steep descent situations.

Example embodiments relate to corrugated radomes for protecting and concealing components of radar units. An example radar system may include a radar unit that includes at least one antenna having a radiation pattern. The radar unit is configured to transmit a radar signal based on the radiation pattern and receive radar signals. In addition, the radar system further includes a radome located in a direction of transmission of the radiation pattern. Particularly, the radome includes a stepped surface having at least one step that includes a height equal to one-quarter of a wavelength at a frequency of operation of the radar unit. The least one step is positioned on the radome such that the at least one step causes deconstructive interference of reflections of the transmitted radar signal caused by the radome.
