A method of forming a three-dimensional object is carried out by: providing a carrier and an optically transparent member having a build surface, the carrier and the build surface defining a build region therebetween; filling the build region with a polymerizable liquid; irradiating the build region through the optically transparent member to form a solid polymer from the polymerizable liquid while concurrently advancing the carrier away from the build surface to form the three-dimensional object from the solid polymer, while also concurrently: (i) continuously maintaining a dead zone of polymerizable liquid in contact with the build surface by electrochemically generating a polymerization inhibitor therein from a precursor of the polymerization inhibitor, and (ii) continuously maintaining a gradient of polymerization zone (e.g., an active surface) between the dead zone and the solid polymer and in contact with each thereof, the gradient of polymerization zone comprising the polymerizable liquid in partially cured form. Apparatus for carrying out the method is also described.

In a vehicle door assembly, controllers processes signals from an extension force sensor and a retraction force sensor to control a door handle. As a motor retracts the handle, a swing arm in the vehicle door presses against the retraction force sensor causing the handle controller to stop the motor. Pushing on the retracted handle presses the swing arm against the retraction force sensor a second time causing the controllers to operate the motor and extend the handle. As the handle extends, the swing arm presses against the extension force sensor and the handle controller stops the motor as the handle is fully extended. Subsequently, a hand pulling on the door handle presses the swing arm against the extension force sensor a second time causing the controllers to unlatch a latch holding the vehicle door shut, and thereby allow the vehicle door to open.

Controller apparatus and sensors for a vehicle door handle

A door handle assembly for a vehicle door includes a door handle operated using a controller and sensors. In the door interior, an upper portion of a swing arm connects to a first post and a second post portion of the door handle. The lower portion of the swing arm, rotably attached to a shaft on the inner door, pivots between an extended and retracted position. When an extension force sensor contacts the upper portion of the arm, the extension force sensor on the inner door surface generates an extension force response signal. A retraction force sensor on the lower portion of the arm generates a retraction force response signal when the retraction force sensor on the lower portion of the arm contacts a flush adjuster rod. Both extension and retraction force response signals are used by the controller to operate the door handle.

A method of charging a rechargeable battery pack installed in an electric vehicle is provided in which the charging system includes a switching circuit that is operable in at least a first mode and a second mode. In the first mode the switching circuit couples the power supply and an external power source to both a heater and the charging circuit, the heater providing a voltage divider circuit within the charging circuit. In the second mode the switching circuit couples the power supply and the external power source only to the charging circuit, bypassing the heater.
