| 20090148258 | PICK AND PLACE APPARATUS INCORPORATING DEBRIS REMOVAL DEVICE - A pick and place apparatus is provided for picking up an electronic component from one location and placing it at another location, which comprises a pick up tool having an opening at which electronic components are configured to be held by vacuum suction. An air channel extends through the pick up tool from the opening and is connectable for fluid communication with an air supply source which is operative to blow a quantity of air out from the opening towards the electronic component for removing any debris located thereon. The air channel is also connectable for fluid communication with a vacuum suction source which is operative to generate vacuum suction force at the opening for picking up the electronic component by vacuum suction. | 06-11-2009 |

| 20080293410 | METHOD AND SYSTEM FOR SENSING DISCONTIGUOUS CHANNELS IN A WIRELESS NETWORK - A method for sensing channel availability in a wireless network includes receiving a measurement request message which includes a channel interval list. A first channel interval in the list includes information associated with a first starting channel number, a first number of channels, and first linkage information of the channel interval list. The method includes processing information associated with the message, generating a first list of contiguous channels, and performing at least first channel measurement to determine a first channel availability for each of the first list of contiguous channels. The method also includes determining whether the channel interval list further includes a second channel interval that needs to be processed based on at least first linkage information, and if needed, generating a second list of contiguous channels and performing at least second channel measurement to determine a second channel availability for each of the second list of contiguous channels. | 11-27-2008 |
