Assignee:

Ford Global Technologies, LLC - Dearborn MI

International Classification:

B60R 11/02

Abstract:

A vehicle includes an instrument panel, a support structure coupled to the instrument panel, and a retainer. The support structure defines a receiver that extends from a lower end to an upper end that is vehicle-upward of the lower end. The portion of the support structure that defines the receiver includes at least one rib that protrudes into the receiver. The retainer includes a barrel portion having a threaded interior surface that defines a hollow and an exterior surface opposite the interior surface and having at least one wing. The retainer also includes a head portion coupled to the barrel portion. The retainer is operably coupled to the support structure, such that the barrel portion is received within the receiver and the at least one wing of the exterior surface is engaged with the at least one rib to maintain the retainer within the receiver.

International Classification:

H04B 7/185
H04W 16/28
H04W 4/46

Abstract:

A drone communication system is described. Using the system, a method may be executed that includes: when a recipient vehicle is out of wireless range, transmitting a message, from a sending vehicle, to a plurality of drones that are focusing antenna beams on the sending vehicle so that the plurality then may transmit the message to the recipient vehicle by focusing antenna beams thereon.

International Classification:

B29C 64/135
B22F 3/105
B29C 64/153

Abstract:

An article includes a body that has a solid shell that encloses an interior region. The interior region has a solid sub-region, a lattice sub-region, and a hollow sub-region that are exclusive of each other and distributed based on load path. In an example, the article is a spoiler cap, such as for the spoiler on a vehicle.

Appl. No.:

15/331411

Inventors:

- Dearborn MI, US
Harold Bernard Samuels - Farmington MI, US
John Jeffrey Pfeiffer - Saline MI, US

International Classification:

B60G 17/019
B60G 17/018

Abstract:

Various embodiments of the present disclosure provide a ride height sensing system that includes an encoded electromagnetic source as an input unit for a Hall Effect sensors and the signal from the electromagnet is encoded to enable the rejection of ambient magnetic field. In various embodiments, the ride height sensing system includes a self-calibration system including at least one Hall effect sensor mounted at a fixed distance and orientation with respect to the electromagnetic source to provide for continuous calibration of the system. In one embodiment, the enhanced ride height sensing system includes at least two inertial measurement units, such as accelerometers mounted to each of the body frame of the vehicle and the axle frame of the vehicle. This enables the system to optimize power usage by more accurately and efficiently measuring the ride height at high frequency rates with relatively lower power consumption.

International Classification:

B60G 17/016
G01D 5/14

Abstract:

Various embodiments of the present disclosure provide a ride height sensing system that includes an encoded electromagnetic source as an input unit for a Hall Effect sensors and the signal from the electromagnet is encoded to enable the rejection of ambient magnetic field. In various embodiments of the present disclosure, a band pass filter is used for signal processing of the encoded electromagnetic data. Additionally, several Hall Effect sensors may be used with a single electromagnetic source to provide multi-axis sensing and as such, provides robustness in determining ride height changes, or in the case of dependent suspensions (solid axle), a single electromagnetic source can used to determine ride height at multiple locations on the axle.
