Abstract: Systems and methods may create and deliver digital advertisements in a delivery ad network. In one implementation, a method may include receiving, by a processor, a digital advertisement. The digital advertisement may include data associated with a product. The method may also include linking, by the processor, the digital advertisement to the product. The linking may include associating a unique identifier associated with the digital advertisement to a unique identifier associated with the product. The method may further include preparing, by the processor, the digital advertisement for delivery. The preparation may include determining a destination device associated with a user. The method may further include transmitting, by the processor, the digital advertisement to the destination device associated with the user, and the transmission may be triggered by a predetermined set of rules.

Abstract: In one embodiment, an improved transceiver assembly for a vehicle capable of detecting potentially hazardous objects is disclosed. The transceiver assembly comprises a tapered slot feed antenna for generating a beam and for detecting the beam as reflected from the potential hazards. The antenna is formed in or on a housing which also contains a parabolic dish that oscillates to sweep the beam of radiation towards the potential hazards outside of the vehicle. In a preferred embodiment, approximately 77 GHz radiation is generated from and detected by the antenna. The antenna is preferably formed on a printed circuit board (PCB) (substrate), which can include additional circuitry necessary to operate the antenna, and which is preferably mounted at an acute angle with respect to the housing to direct the beam at the parabolic dish.

Abstract: High quality epitaxial layers of monocrystalline materials can be grown overlying monocrystalline substrates such as large silicon wafers by forming a compliant substrate for growing the monocrystalline layers. An accommodating buffer layer comprises a layer of monocrystalline oxide spaced apart from a silicon wafer by an amorphous interface layer of silicon oxide. The amorphous interface layer dissipates strain and permits the growth of a high quality monocrystalline oxide accommodating buffer layer. The accommodating buffer layer is lattice matched to both the underlying silicon wafer and the overlying monocrystalline material layer. Any lattice mismatch between the accommodating buffer layer and the underlying silicon substrate is taken care of by the amorphous interface layer. Once such a structure is built, a high electron mobility transistor (HEMT) or a heterojunction bipolar transistor (HBT) can be constructed on the structure.
