A system and method allowing wager(s) to be placed over a wireless network using a remote device by authenticating an established user account, and validating the location of the player using network centric data. The player utilizes the remote device, which may be a cell phone or remote computing device, connected securely to a wagering system over a wireless network (e.g., 3G). Depending on the type of game, player location is determined using A-GPS and/or control plane technology utilizing carrier network information. Wagers may be placed using verbal instructions or keypad entries which communicate with a voice recognition system, dedicated software application, live operator and/or web browser based application. Regardless of the wager placement methodology, the remote device is linked to a wager server and location verification is specific to the subject remote device connected thereto. Other methods of verifying location are utilized as safeguards against spoofing and remote operation.

A method and apparatus for correcting vision, including a corneal-pocket keratome device to create a corneal pocket and a lens to be inserted and retained in the corneal pocket to effect correction. The corneal-pocket keratome includes a drive unit having cutting head elements which contact the subject eye during corneal pocket formation. The cutting head elements may be removeable and may be disposable. The cutting head elements include a corneal restraint device, which may be a positioning ring to position an eyeball with the cornea protruding through the ring; a keratome blade assembly with a corneal-pocket blade; and may also include an applanation shoe surface to restrain the cornea, in addition or instead of the positioning ring. The applanation shoe may be pivotable away from the surgical area. The corneal-pocket blade may include a guide which travels with the blade. The blade assembly oscillates laterally while extending forward into the cornea to form the pocket, and the amplitude of the lateral oscillation is preferably increased as the blade goes beyond an opening incision into the cornea. Lenses for this invention preferably include a feature to impede accidental lens movement after the lens is disposed within the corneal pocket, which may be a swelling after insertion or a circumferential irregularity. Lenses may be of Fresnel or non-Fresnel type, and may employ annular changes in the index of refraction of the lens material, as well as changes in refractive shape which may be annular or not, to effect variations in focal length for relieving presbyopia, astigmatism, and combinations of those as well as myopia and hyperopia. Drive control and vacuum for the positioning ring are provided under user command by a control unit having user inputs.

The invention discloses a deep learning-based quick automatic capture and placement method. The method can quickly and accurately determine positions and attitudes of articles in combination with a GPU and a 3D camera by adopting a deep learning scheme. Through a quick calibration scheme, a transfer matrix from a coordinate system of the 3D camera to a coordinate system of a mechanical arm can beobtained. The transfer matrix can convert the positions and attitudes of the articles to the coordinate system of the mechanical arm, and then operate the mechanical arm to perform capture. For accurately placing the articles in a specific mode, the articles are subjected to secondary attitude estimation. A secondary attitude estimation process comprises the steps of firstly capturing the articlesto an estimation position by fixed attitude; at the moment, segmenting out the articles more completely by only using depth information; projecting the articles to a placement plane; and performing accurate attitude estimation for information on the plane, thereby enabling the mechanical arm to perform placement.
