    Abstract: A thermal control system includes a component having a surface. A plurality of thermal generating devices include a first conductive plate, second and third conductive plates, a first semiconductor device arranged between the first conductive plate and the second conductive plate, and a second semiconductor device arranged between the first conductive plate and the third conductive plate. The first semiconductor device and the second semiconductor device have different types of doping. First ones of the plurality of thermal generating devices are arranged with the first conductive plate located adjacent to the surface of the component. Second ones of the plurality of thermal generating devices are arranged with the second and third conductive plates located adjacent to the surface of the component. The first ones and the second ones of plurality of thermal generating devices perform heating and cooling of the surface, respectively.

    Abstract: An inflatable system includes a first bladder configured to contain gas and a second bladder configured to contain gas. The first bladder includes a top wall, a bottom wall opposite of the top wall, a sidewall extending between and connected to perimeter edges of the top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of the top and bottom walls. The second bladder includes a top wall, a bottom wall opposite of its top wall, a sidewall extending between and connected to perimeter edges of its top and bottom walls, and a plurality of tethers extending between and connected to interior surfaces of its top and bottom walls. The bottom wall of the first bladder is secured to the top wall of the second bladder.

    IPC: G05D16/06

    Abstract: A pressure regulator includes an inlet channel, an outlet channel, a bladder, a first plate, and a second plate. The bladder is connected to the outlet channel and extends alongside of the inlet channel. The first plate is disposed on one side of the inlet channel between the bladder and the inlet channel. The second plate is disposed on the other side of the bladder and is at least partially aligned with the first plate along the length of the inlet channel such that a portion of the inlet channel is disposed between the first and second plates. When the bladder is pressurized, the bladder urges the first plate toward the second plate and thereby pinches the portion of the inlet channel disposed between the first and second plates to regulate a ratio of a pressure in the outlet channel to a pressure in the inlet channel.

    CPC classification number: F03G7/06

    Abstract: Some on-vehicle devices, such as air dams, air spoilers, and HVAC system baffles, may have movable components that are pulled from one position to another by shrinkage of a linear shape memory alloy (SMA) actuator. Upon an activation signal, the shrinkage of the SMA actuator occurs when it is resistance heated by an electrical current. It is found that useful information concerning the overall intended operation of the on-vehicle device may be obtained by computer analysis of the temporal variation of both current flow through the actuator and its electrical resistance as it is heated to perform its function in the device. A comparison of present current flow and variation of resistance, during activation of the device, with prescribed stored values can reveal malfunction of components of the device as it is being used, in place, on the vehicle.

    Abstract translation: 一些车载设备，例如空气坝，空气扰流器和HVAC系统挡板，可以具有通过线性形状记忆合金（SMA）致动器的收缩从一个位置拉动到另一个位置的可移动部件。 在激活信号时，当SMA电阻被电流加热时，​​SMA致动器的收缩发生。 发现关于车载设备的总体预期操作的有用信息可以通过对通过致动器的电流的时间变化及其被加热以在其中执行其功能的电阻的计算机分析来获得。 在设备激活期间，当前电流和电阻变化与规定的存储值进行比较可以显示设备在组件被部署在车辆上时的故障。

    Abstract: An inflatable lift system for a vehicle includes N bladders arranged vertically in a stack, where N is an integer greater than two. N pressure sensors are configured to sense pressure in the N bladders, respectively. A compressor is configured to supply pressurized gas. N valves are configured to selectively connect and disconnect the N bladders to the compressor. A controller is configured to control the N valves to inflate the N bladders sequentially in a first predetermined order and to deflate the N bladders sequentially in reverse.
