A novel and useful safety functionality assurance mechanism incorporating an RF built in self-test (RFBIST) system in a radar system having a plurality of transmitter devices and receiver devices. The RFBIST functions to verify, inter alia, that the transmitted signal is operating correctly and that all channels transmit a proper, valid or 'legal' signal and that the receiver devices are also operating correctly. A higher level of safety assurance is achieved by comparing safety data between the receiver devices. In one embodiment, the signal received from the various transmitter devices is compared. The RFBIST circuit block eliminates the physical transmit antenna position properties to compare the transmitted signal properties after signal path elimination. Thus, the present invention is capable of (1) validating multiple transmitter devices with a single receiver device and (2) validating multiple receiver devices with a single transmitter device. When receiver devices detect a fault and that particular device is the master device, then a mechanism is provided to shut down the master device and making a slave device the new master device.

A novel and useful system and method for eliminating settling time delays in a radar system. In one embodiment, a plurality of oscillators is provided with a single transmitter. In an alternative embodiment, a plurality of transmitters is provided, each with its own oscillator. In either case, more than a single oscillator is used, whereby startup or turn on transients associated with one oscillator are allowed to settle out while another oscillator is being used. The two or more oscillators switch off and/or alternate or rotate such that oscillator settling time between chirp transmissions from the radar is substantially or completely eliminated. In a radar system having two transmitters, when the chirp propagation time window for the first transmitter is complete, the first transmitter is disconnected from the receive channel and the second transmitter is connected to the antenna and receive channel without having to wait for the second transmitter to settle since it was allowed to settle beforehand.

A novel and useful radome suitable for use in an automotive radar system that employs patch antenna arrays. In one embodiment, the radome is a 'U' shaped half cylinder for patch antenna arrays such as on a printed circuit board (PCB). The patch antennas may or may not be situated in the same plane. Each array has its own half cylinder associated with it. Each array may have a different antenna pattern with different gain and side lobes. In this case, each patch antenna array has its own radome configured appropriately. Alternatively, the radome comprises a half sphere shape (or bubble shape) whereby each antenna port has its own individual half sphere shaped radome. This functions to improve the performance of the radome by increasing the number of curved dimensions from one to two.

An energy storage and regeneration system that converts irregular, non-constant, and variable input power to regular, constant, and controlled output power using hydraulics whereby the irregular input power is used to pump hydraulic fluid into an accumulator array where it is stored pressurized. Energy is released in a controlled fashion using a hydraulic motor operated by the pressurized hydraulic fluid from the accumulator array, in accordance with the specified power demand. One or more power units may be deployed depending on the amount of energy required at the output. Each power unit includes a hydraulic motor and associated floating accumulator whose internal pressure is controlled to maintain a substantially constant pressure differential across its associated motor. The system can be integrated into various energy system sources including renewable energy such as wind, PV or thermal solar, wave, tidal, etc. as well as various types of vehicles such as cars, trucks, motorcycles, trains, boats, etc.
