202results about How to "Avoid image distortion" patented technology

A circuit powering an electrical device based on a commanded current signal is provided. The circuit includes a linear current amplifier which sets a desired current flow. The circuit also dynamically controls a supply voltage in order to minimize power dissipation of the linear current amplifier. The circuit may also include a voltage drop measurement amplifier, a voltage shaping amplifier, and a switching power supply. The circuit is useful for controlling electrical devices requiring precise current control and minimal power dissipation, for example, driving light-emitting diodes (LEDs) that provide illumination inside the passenger compartment of a vehicle for an imaging occupant detection system.

A system and method for delivering one or more implantable members, such as metal coils, via an introducer member, such as an endoscopic needle, into a space created within the submucosal layers of the LES to augment and bulk the sphincter to improve compliance in patients with gastroesophageal reflux disease. The implantable member comprises a first substantially straightened configuration when carried by the introducer member, whereby it assumes a more curvilinear or coiled configuration following deployment such that it expands against adjacent submucosal tissue, creating a bulge at the implantation site. In another embodiment, the implantable member can serve as an anchoring port for sutures or other elements introduced for gastroplication of the LES to create tissue folds that increase sphincter compliance. The implantable members may be configured to include an external portion that interconnects with an adjacent implantable member, thereby creating tension that also increases compliance of the LES.

The image forming apparatus comprises: a recording head which ejects droplets of a liquid onto a recording medium; a droplet ejection control device which controls a droplet ejection timing of the recording head; and a conveyance device which relatively moves the recording medium and the recording head in a relative conveyance direction, wherein when the recording head performs ejection of a first droplet to form a first dot on the recording medium and then performs ejection of a second droplet to form a second dot overlapping with the first dot on the recording medium, the droplet ejection control device controls the droplet ejection timing of the recording head by taking a droplet diameter change time until a diameter of the first droplet deposited on a surface of the recording medium reaches D1b satisfying the following inequality as a droplet ejection time interval between the ejection of the first droplet and the ejection of the second droplet: D1b<2×Pt−D2a, where Pt is an interval between the first dot and the second dot on the surface of the recording medium, D2a is a diameter of the second droplet upon landing on the surface of the recording medium, and D1b is the diameter of the first droplet on the surface of the recording medium when the second droplet lands on the surface of the recording medium.
