    摘要: A MIMO radar transceiver assembly includes a plurality of transceiver circuit regions and a plurality of antennas. The plurality of antennas include a first transmit antenna coupled to a first transceiver circuit region among the plurality of transceiver circuit regions, a first receive antenna coupled to the first transceiver circuit region, a second transmit antenna coupled to a second transceiver circuit region among the plurality of transceiver circuit regions, and a second receive antenna coupled to the second transceiver circuit region. At least one of the second transmit antenna and the second receive antenna is interleaved between the first transmit antenna and the first receive antenna. Interleaving of the antennas can increase virtual aperture and angular resolution of the radar system without increasing physical dimensions of the transceiver assembly.

    摘要: Purified nucleic acids, vectors and cells containing a gene cassette encoding at least one modified bioluminescent protein, wherein the modification includes the addition of a peptide sequence. The duration of bioluminescence emitted by the modified bioluminescent protein is shorter than the duration of bioluminescence emitted by an unmodified form of the bioluminescent protein.

    摘要: A conventional grenade shell launcher contains a laser generator shell thin which directs a blinding flash of light at an adversary to temporarily induce blindness of the adversary carrying out unlawful or dangerous actions such as pointing a weapon at police officers or others. The laser generator shell can be rapidly removed from the launcher, and conventional tear gas grenades or the like can be fired by the grenade launcher at the adversary to induce his surrender. This mode of operation is enabled by detachably coupling a laser triggering transmitter to the launcher. The wide angle light beam directed at the adversary also eliminates the need to accurately aim the device to disable the adversary.
