20090267286 | METHOD AND APPARATUS FOR SEPARATING MEDIA COMBINATIONS FROM A MEDIA STACK - The present invention provides a method and apparatus separating a media combination from a stack of interleaved slip-sheets and printing plates and relates to image recording systems such as, for example, computer-to-plate (CTP) systems. Image recording systems include imaging systems that image an image recordable material in response to imaging information. Image recordable materials can include, for example, printing plates. Image recording systems can include integrated systems that additionally process the image forming materials. Additional processing can include, but is not limited to materials punching, materials bending, exposure to non-imaging radiation, chemical development and materials drying. The present invention relates to a materials handling system that separates a media combination from a media stack that includes image recordable materials. A slip-sheet separates each of the image recordable materials from one another in the media stack. The image recordable materials removed from the stack are subsequently imaged and optionally additionally processed. The slip-sheets removed from the stack are stored in a slip-sheet holder. | 10-29-2009 |

20110310862 | Method and apparatus for affiliating a wireless device with a wireless local area network - The present invention provides a system and method for affiliating a wireless device with a wireless local area network (WLAN). An embodiment of the method of this invention comprises establishing, at a control node of the WLAN, access frequency(s) for affiliation with the WLAN. The control node periodically provides a beacon frame on the access frequency(s) that indicates the timing of affiliation with the WLAN. The wireless device determines the access frequency(s) for affiliating with the WLAN and the timing of affiliation with the WLAN based on the beacon frame. The wireless device provides self identification information via the access frequency during the beacon frame. This allows the control node to determine the access privileges of the wireless device based on the identification information. Finally, the control node affiliates the wireless device with an initial access channel from a set of access channels in accordance with the access privileges. | 12-22-2011 |
