  • Patent number: 11916793
    Abstract: The performance and ease of management of wireless communications environments is improved by a mechanism that enables access points (APs) to perform automatic channel selection. A wireless network can therefore include multiple APs, each of which will automatically choose a channel such that channel usage is optimized. Furthermore, APs can perform automatic power adjustment so that multiple APs can operate on the same channel while minimizing interference with each other. Wireless stations are load balanced across APs so that user bandwidth is optimized. A movement detection scheme provides seamless roaming of stations between APs.

  • Publication number: 20060284114
    Abstract: A technique for uniformity tuning in an ion implanter system is disclosed. In one particular exemplary embodiment, the technique may be realized as a method for ion beam uniformity tuning. The method may comprise generating an ion beam in an ion implanter system. The method may also comprise tuning one or more beam-line elements in the ion implanter system to reduce changes in a beam spot of the ion beam when the ion beam is scanned along a beam path. The method may further comprise adjusting a velocity profile for scanning the ion beam along the beam path such that the ion beam produces a substantially uniform ion beam profile along the beam path.

  • Publication number: 20060091208
    Abstract: A method of identifying or authenticating a product by providing an analog identification indicium including a randomized pattern of identification features on a first part of the product wherein one or more attributes of the randomized pattern of identification features correspond to an item identifier. A digital identification record is provided on a second part of the product including an encoded digital version of the item identifier, the first and second parts being separable when the product is used. The randomized pattern of identification features of the analog identification indicium is read and decoded to generate an item identifier and the digital identification record is read and decoded to generate an item identifier. The product is deemed authentic if the item identifier from the analog identification indicium substantially matches the item identifier from the digital identification record.

  • Publication number: 20060095778
    Abstract: An authentication-enabled indicium contains authentication information in a digital recording medium. The information may be a digital signature that verifies the manufacturer's data and/or an analog signature. The analog signature is generated by placing a randomized pattern on a product package or label and encoding information about the randomized pattern in the digital recording medium for verification. The randomized pattern may be made up of color-shifting features imbedded in the label that are visible when illuminated with UV or infrared light. Characteristics of the reflected light when the features are illuminated is used to generate an analog signature that is encoded in the recording medium. During processing the features are illuminated and a new analog signature is determined for comparison with the signature recorded in the digital recording medium.

  • Patent number: 4056846
    Abstract: In a data processing system having a plurality of channels that are organized for separately processing the operations of specific I/O devices and the operations that are background to these specific operations, apparatus for transferring the background processing from one channel to another channel to distribute the background processing load. A system of registers and lines connect these registers to the channels for controlling these operations. Each channel processor has a request register for use in designating that background processing has been completed and that processing of a device oriented portion of a channel program is to begin, and a completion register set by an associated I/O processor for use in signifying that processing of a device oriented portion of a channel program has been completed and that background processing is to begin.

  • Patent number: 4048671
    Abstract: Apparatus for signalling the occurrence of a match between an address that is supplied to a control store and an address that is to be watched for in a data processing system that executes several instruction streams concurrently. The apparatus signals the occurrence of a storage accessing operation at a location that is uniquely identified only by a virtual address that is longer than the actual address used in accessing the store. Means is provided for comparing the actual address used in accessing the store with the corresponding portion of the complete address, and means is provided for recording the location of an address to be watched for in a particular frame of the store and for signalling a match that occurs in such a frame. The apparatus is useful for testing the operation of the data processing system by relating a recurring malfunction of the system to the execution of an instruction at the address that is watched for.
