    Abstract: A haptic device includes a first signal generator embedded in a host and configured to generate a first haptic signal. A first waveguide is operatively connected to and configured to transmit the first haptic signal away from the first signal generator. A first integrator is operatively connected to the first waveguide and configured to receive the first haptic signal. The first waveguide and the first integrator are in mechanical communication with the host. The first waveguide may include a first bent portion characterized by a first bend angle. An additional waveguide may be configured to transmit the first haptic signal to the first integrator. The additional waveguide may include an additional bent portion characterized by a second bend angle. The haptic device may be part of a seat assembly, where the host is at least one of a seat bottom, a seat back and a head rest.

    Abstract: An electric motor includes a rotor having a stack of laminations positioned axially relative to one another. The stack of laminations includes a first rotor lamination that is divided into a first portion and a second portion. The first rotor lamination is configured to have an asymmetric mass distribution such that the first portion has a first mass and the second portion has a second mass, with the first mass being different from the second mass. The electric motor is configured to selectively generate an unbalanced force during operation (i.e., when the rotor is spinning). The electric motor may include a stator configured to have an asymmetric magnetic field distribution. The electric motor may be employed in a haptic assembly and eliminates the need for a separate eccentric mass to generate a haptic signal.

    Abstract: An occupant support structure and a method of customizing an occupant support structure. The occupant support structure may comprise a base and a reconfigurable cushion carried by the base. The reconfigurable cushion may include an occupant support surface and a bladder. The bladder may include an outer wall that defines an inner cavity underlying the occupant support surface and two or more overlapping material layers disposed within the cavity. The overlapping material layers may be adapted to selectively transition from a compliant state to a rigid state and vice versa by selective control of a pressure condition across the outer wall of the bladder to reconfigure or conform the occupant support surface of the cushion to a contour of a portion of an occupant supported by the cushion.

    Abstract: A textile assembly includes a knitted or woven textile panel of non-conductive fibers, and defines a first delimited area. A first conductive filament is knitted or woven into the textile panel in the first delimited area, and is arranged to form an electronic device, such as a sensor or a switch, in the first delimited area. The textile assembly may further include a third conductive filament that is knitted or woven into the textile panel in a second delimited area. The third conductive filament is arranged to form a second electronic device, such as a sensor or a switch, in the second delimited area. A controller may use a signal from the first electronic device and the second electronic device to execute a function, such as generate a pressure map of the textile panel.

    Abstract: An energy absorber according to various embodiments can include a structure having a predetermined cross-sectional profile. A hollow profile is formed within the structure. The pre-determined cross-sectional profile of the structure is configured based on a deceleration-time profile that includes a first period and a second period. The first period is defined by a substantially sharp and linear increase in magnitude of the deceleration of an impact until a maximum deceleration value is achieved. The second period is defined by a rapid decrease in the magnitude of the deceleration.

    Abstract: Methods for welding sandwich structures together, especially vehicle structures, where the structures include two opposing face sheets with a core, such as a micro-truss core, therebetween. In one embodiment, two sandwich structures are butt welded together. A cooling fluid barrier is provided at an end of the core between the face sheets to prevent cooling fluid from entering the core during the welding process, where the cooling barrier can be a micro-truss structure and can include cooling fluid channels. A welding insert is inserted into the end of one of the structures adjacent to the cooling barrier, and is welded to the other structure to secure the structures together.

    Abstract: An approach to designing lightweight metal-polymer composite structures in a manner that decomposes the structure into at least two parts. In one specific embodiment, the approach is a manufacturing process for a vehicle that includes attaching an impact beam to a vehicle structure. The process includes providing a vehicle structure including a back plate of the impact beam being made of a suitable material, such as a metal, that can withstand high temperature processes. A front part of the impact beam including a front plate and a polymer core is attached to the back plate. The back plate is designed to provide structural integrity that allows the vehicle structure to go through the high temperature processes and/or the vehicle structure provides structural integrity that allows the back plate to go through the one or more processes. The back plate is also designed to provide desired functional characteristics of the beam.
