Abstract: an ultra wide band (uwb) antenna is described and includes: a planar portion arranged above and parallel to a ground plane; a ground connecting portion configured to electrically connect the uwb antenna to the ground plane; a tapered portion, the tapered portion extending around at least 40 percent of a periphery of the planar portion and extending perpendicularly from the planar portion toward the ground plane, where a height of the tapered portion decreases around the periphery of the planar portion moving away from the feed, and where a lower edge of the tapered portion is spaced from the ground plane by a gap; and a radio frequency (rf) balun, where a feed is configured to be electrically connected between the rf balun and the tapered portion.

CPC Code(s): H02K1/32
Abstract: a radial flux electric motor includes a stator having a radially inner stator surface and a rotor mounted inside the stator. the rotor defines a rotational axis and has axially opposite rotor ends and a radially outer rotor surface positioned proximate the radially inner stator surface, thereby establishing an airgap therebetween. the rotor also includes a fluid circulation arrangement having at least one fluid channel extending through the rotor to the radially outer rotor surface and configured to receive a liquid via a first passage and a gas via at least one second passage. the fluid circulation arrangement is also configured to direct the liquid and the gas, via centrifugal force, into the airgap as the rotor rotates inside the stator sufficiently to discharge the liquid and the gas out of the airgap at the axially opposite ends of the rotor, thereby cooling the electric motor.

Abstract: a system for a vehicle comprises a wifi station, data processing hardware including, and memory hardware in communication with the data processing hardware, the memory hardware storing instructions that when executed on the data processing hardware cause the data processing hardware to perform operations comprising detecting an access point, establishing a link between the access point and the wifi station, obtaining recent yaw rate data of the vehicle, obtaining recent speed data of the vehicle, obtaining recent acceleration data of the vehicle, obtaining recent mobility pattern data of the vehicle based on geolocation data and map data, and determining optimal physical (phy) parameters corresponding to highest data rate based on at least one of the recent yaw rate data, the recent speed data, the recent acceleration data, or the recent mobility pattern data.
