| 20110079209 | RIGID GRILL STRUCTURE - A cart suitable for supporting a grill, including a grill bowl. The cart has two union members with curved channels for receiving tubular, U-shaped frame members. The union members may be in the form of two similar (but not necessarily identical) halves joined together to enclose the frame members. The tubular channels of the union members resist movement (such as twisting and tilting) in at least two directions. The union members lock the frame members in place with internal protrusions that fit into mating depressions or holes in the frame members. Extra rigidity is added to the cart by one or more side tables which are structural members as well as functional tables. The side tables thus serve as cross-members between two frame assemblies. The grill's lid can easily be tilted back to rest in place on lid supports underneath the bottom edge and contact points on the side tables. | 04-07-2011 |

| 20090216841 | IDENTIFYING IP ADDRESSES FOR SPAMMERS - Detecting and blocking spam messages using statistical analysis on distributions of message sizes for a given IP address. Mail volumes are examined to model a distribution of volumes to cluster IP addresses. The messages sizes may distributed across ranges of message sizes, which is then used to determine an entropy of message sizes for the given IP address. The entropy of the given IP address may be compared to entropies of known good IP addresses, and if a difference between the entropies is statistically significant, then the given IP address may be determined to be an IP spammer. User feedback may also be employed to further characterize an IP address. For example, a number of messages from the IP address may be sent to intended recipients. User feedback may then be monitored to determine whether to the IP address should be reclassified. | 08-27-2009 |
| 20090220166 | FILTER FOR BLOCKING IMAGE-BASED SPAM - A network device and method are directed towards detecting and blocking image spam within a message by employing a weighted min-hash to perform a near duplicate detection (NDD) of determined features within an image as compared to known spam images. The weighting for the min-hash is determined based on employing a machine learning algorithm, such as a perceptron, to identify an importance of each bit in a signature vector of the image. The signature vector is generated by extracting a shape of text in the image using a Discrete Cosine Transform, extracting low-frequency characteristics using a high-pass filter, and then performing various morphological operations to emphasize the shape of the text and reduce noise. Selected feature bits are extracted from the lowest frequency and intensity bits of the resulting signal to generate the signature vector used in the weighted min-hash NDD. | 09-03-2009 |
