Microwave radar systems using compact form factor devices are described. Examples of such devices include a 'folded' beamformer. The beamformer includes: a linear array of microwave antennas; a principal plane including: a Rotman lens; a first set of coplanar microwave waveguides; and a second set of coplanar microwave waveguides; and a series of one or more first planes parallel to the principal, each first plane including the first set of waveguides. Each plane of the beamformer includes one or more sets of miter bends, each set of miter bends configured to redirect waveguides of the first or second set. The beamformer can be configured for use in a radar system, either as a receiver (RX) beamformer, a transmitter (TX) beamformer, or as a combined transceiver (TRX) beamformer. The radar system can also include a second beamformer for receiving and transmitting using two separate beamformers.

A system and rack includes an antenna subsystem having a preexisting processing pipeline that receives radio frequency returns and an upgraded signal processing pipeline that performs detection processing for the antenna subsystem. The upgraded signal processing pipeline couples to the preexisting processing pipeline. The upgraded signal processing pipeline includes sampling converters to sample the radio frequency returns of the antenna subsystem, field-programmable gate array devices to generate detection data of the radio frequency returns at full-bandwidth and full-range of the antenna subsystem, graphics processing units to apply algorithms to the detection data of the radio frequency returns, and a signal processor configured to perform operations on the sampled radio frequency returns. The operations can include sampling returns, down-converting sampled detections, filtering detections, digitizing radio frequency returns, and applying algorithms to generate output data. The output data can be provided to the preexisting processing pipeline of the antenna subsystem.

A radar system includes a transmit front end device including a transmit planar component, and a receive front end device including a receive planar component. Each of the transmit planar component and the receive planar component includes a first end, a second end, a cavity space and a linear array of antennas. The cavity space is bounded by beam ports along a first side of the cavity space and by array ports along a second side of the cavity space. The cavity space is in operative communication with the beam ports and with the array ports to form a Rotman lens. A linear array of antennas is located along the second end of the planar component. The transmit planar component and receive planar component are arranged such that the linear array of antennas of the transmit planar component and the linear array of antennas are perpendicular to one another.

An acoustic cleaving system are described for initiating and controlling crack propagation. In an embodiment, the system includes an acoustic generator that includes a piezoelectric device; a high-voltage power supply; and an acoustic cleaving circuit. The acoustic cleaving circuit includes a push-pull circuit coupled to the piezoelectric device and coupled to the high-voltage power supply, and a capacitor bank that includes one or more capacitors coupled in parallel to the push-pull circuit. In one embodiment, the push-pull circuit is for receiving at least one input signal and for producing an amplified output signal to drive the piezoelectric device.

A front end of a radar system is provided with a first front end apparatus and a second front end apparatus. A first transmit planar component and a first receive planar component in the first front end apparatus are arranged to be perpendicular to one another. A second transmit planar component and a second receive planar component in the second front end apparatus are arranged to be perpendicular to one another. A linear array of antennas is located along a second end of each planar component. Polarization of a first set of waves transmitted from the linear array of antennas of the first transmit planar component and polarization of a second set of waves transmitted from the linear array of antennas of the second transmit planar component are perpendicular to one another.

Structures and methods to actively control the shape of a micro pickup array (MPA) during micro device transfer are described. In an embodiment, a strain is applied to the MPA counteractive to strain arising during micro device transfer operations. For example, strain may be applied by a piezoelectric actuator element bonded to a back side of the base substrate to control a curvature of base substrate, and by extension the MPA.

Aspects of the invention provide improvements to electromagnetic and other wave-based ranging systems, e.g., RADAR or LIDAR systems, of the type having transmit logic that transmits a pulse based on an applied analog signal. The improvements are characterized, in part, by a SERDES having a serializer (a/k/a a 'transmit side') that is coupled to the transmit logic. The serializer has (i) an input to which a pattern on which the pulse is based is applied and (ii) an output from which a serialization of the pattern is applied to the transmit logic. The improvements are further characterized in that the SERDES has deserializer logic (a/k/a a 'receive side') that is coupled to receive logic and that deserialize a received &#x201c;analog&#x201d; signal containing possible reflections of the pulse. According to various aspects of the invention, the transmit and/or receive logic can include circuitry for directionally steering pulses transmitted into the environment and/or the directional sensitivity of the system to possible reflects of those pulses.
