A gas-liquid separator includes a chamber having an inlet for liquid to enter and at least one outlet for expulsion gas and/or vapour that has separated from the liquid within the chamber under gravity. For some applications the chamber will also have an outlet for the liquid. These systems can rely on the chamber remaining in a static orientation with the gas outlet arranged uppermost. Exemplary embodiments provide the chamber with multiple spaced apart outlets and an ability to sense orientation and/or acceleration of the chamber. A controller uses the output of the sensors to determine the spatial arrangement of the liquid phase and gas phase within the chamber relative to the outlets and selectively opens the multiple outlets to allow one of the liquid phase or gas phase to escape the chamber in preference to the other.

A radar system includes two circuit boards, a first carries an array of antenna elements and the second carries power circuitry to power the circuitry of the first board. To provide adequate cooling whilst minimising the size of the system the two circuit boards are mounted in a sandwich arrangement on opposite sides of a heat sink. Data and power connections between the two boards are provided by a plurality of electrical cables that extend through apertures in the heat sink.

Circuit board assembly

A radar system for air volume surveillance, the radar having a transmitter and receiver with separate antennas. The receiver aperture being relatively large compared with the transmitter aperture such that the receiving beam is narrower than the transmitting beam, which itself is relatively small compared with the volume to be surveyed. Multiple receiving beams can be configured so that collectively they substantially match the angular volume of the transmitting beam; and in which the transmitter is arranged, when operating, to transmit a signal with a duty cycle greater than fifty percent.

The present disclosure relates to manufacture of an active array antenna from a combination of modular sub-arrays, nominally of equal size; each sub-array being associated with a separate receiver and/or transmitter. A solution to calibrating a modular array is the inclusion of a calibration manifold having multiple 1st ports that connect to respective sub-arrays between their passive network and their respective receiver and/or transmitter. Each of the first ports communicate with a common second port through which a signal can be introduced in order to be received at each element of each sub array, or through which a signal from any element of any sub-array can be received. This allows any element of the sub array to be calibrated at any time including during operation.
