Upon connecting with a wireless client, a wireless access point determines predictive roaming information for the wireless client. Predictive roaming information identifies the wireless client; its home network subnet; and includes connection information associated with the wireless client. The wireless access point forwards the predictive roaming information associated with a wireless client to neighboring wireless access points while the wireless client is still connected with the wireless access point. Neighboring wireless access points store received predictive roaming information. Upon connecting with a wireless client, a neighboring wireless access point determines if the wireless client matches the stored predictive roaming information. If so, the neighboring wireless access point uses the predictive roaming information to quickly connect with the wireless client and to establish a tunnel to redirect network traffic associated with the wireless client through to its home subnet. | 08-27-2015 |

20090164853 | SYSTEMS AND METHODS FOR REMOTE MONITORING IN A COMPUTER NETWORK - Systems and methods for providing automated problem reporting in elements used in conjunction with computer networks are disclosed. The system comprises a plurality of elements that perform data migration operations and a reporting manager or monitor agent which monitors the elements and data migration operations. Upon detection of hardware or software problems, the reporting manager or monitor agent automatically communicates with elements affected by the problem to gather selected hardware, software, and configuration information, analyzes the information to determine causes of the problem, and issues a problem report containing at least a portion of the selected information. The problem report is communicated to a remote monitor that does not possess access privileges to the elements, allowing automated, remote monitoring of the elements without compromising security of the computer network or elements. | 06-25-2009 |

20130017279 | FORMULATIONS FOR TREATMENT OF SKIN DISORDERS - The Present Invention teaches herbal formulations based on a non-aqueous extract of wrightia tinctoria and an extract of cocos nucifera, which, when applied topically and used as directed in therapeutically effective amounts, have been clinically proven to be safe and effective for people needing treatment for skin conditions such as reducing or regressing dermal tortuosity, reducing spongiform pustules, and reversing and regressing stratum granulosum in keratinization disorders. The formulations can take the form of an ointment, an oil, a soap, or a shampoo. | 01-17-2013 |
20130247455 | FIRE STARTER - The Present Invention is a fire starting device for use as kindling manufactured from pine straw, as the primary component, a vegetable oil, natural resins, and an herbal component. The composition of the device differs from prior art devices that burn petroleum hydrocarbons. The device is hollow, having at least one vertical channel and at least one horizontal channel drilled from the outer wall of the device to the inner vertical channel. The fire starter device is ignited from the top, and it burns to produce a high, intense flame that ignites other flammable materials having a much greater kindling temperature. The height of the flame and the burn duration are controlled by the overall size of the device and the sizes of the channels. The device burns clean with a minimum of smoke and harmful or noxious fumes. Burning the device minimally creates air pollution. It burns completely with a minimum of ash residue. | 09-26-2013 |

20130078348 | PROCESS FOR PREPARING LOW-CALORIE, LOW-FAT SNACK NUTS - The Present Invention relies upon a physical process for preparing reduced fat, high fiber, high protein, low calorie roasted snack nuts. The process of the Present Invention exhibits significantly lower process times and higher yields than the prior art processes. The process comprises expelling the oil from nutmeat kernels (defatting) using a novel pressing process that takes less than a minute. The defatting process deforms the nuts. The nuts are reformed to their original shape using water. Then the reformed nuts are annealed using cold water to produce hardened nuts. The nuts are then dried and post-processed with coatings and roasting using state-of-the-art technology. The yield of snack nuts produced by this process is generally greater than eighty percent. | 03-28-2013 |
20130078361 | LOW-CALORIE, LOW-FAT SNACK NUTS - The Present Invention is a reduced fat, high fiber, high protein, and low calorie roasted snack nut. The nuts are manufactured using a physical process comprising expelling the oil from nutmeat kernels (defatting) using a novel pressing process that takes less than a minute. The defatting process deforms the nuts. The nuts are reformed to their original shape using water. Then the reformed nuts are annealed using cold water to produce hardened nuts. The nuts are then dried and post-processed with coatings and roasting using state-of-the-art technology. Prior art processes that expel the oil from nuts and reconstitute them produce nuts that easily break and flake. Most of these nuts have an undesirable taste. By contrast, the nuts of the Present Invention have hardness, texture, taste, aroma, and a physical appearance closely approximating that of natural nuts. The shelf life is improved relative to the prior art processes. | 03-28-2013 |
