Abstract: Aspects of the disclosed technology relate to an active array system that can form and steer a directed beam across its aperture. The disclosed array system utilizes a novel configuration that significantly reduces a number of transmit and receive elements. In some aspects, the disclosed array system can be configured with a modular design, for example, to permit the extension of the transmit/receive array, e.g., to increase/decrease aperture size. In other aspects, the disclosed array system may be configured to dispose the elements of either the first or second group of radiators in a modular fashion.

Abstract: Methods and system for alerting a vehicle driver via wireless communications. One or more conditions with respect to a vehicle are monitored. A change in the condition can be detected and a signal automatically and wirelessly transmitted to a computing device, wherein the signal is indicative of the change in condition(s). The driver is then alerted to the change in condition(s) in response to transmitting the signal to the computing device (e.g., a tablet computing device, smartphone, smartwatch, other wearable device, in-vehicle system, etc.) associated with the driver and/or a vehicle passenger.
