20160029775 | COMPRESSION SYSTEM FOR BACKPACK - A compression system for an ergonomic backpack is disclosed. The backpack includes a backpack body having a top side, a bottom side, two lateral sides, a body side, an outer side and a pair of shoulder straps. In the embodiment, each shoulder strap is connected at a junction of the top side and the body side, extended along the corresponding lateral side, threaded through the D-ring with a distal end connected to the backpack body at a junction of the outer side and the lateral side. The invention also comprises an optional back panel and an optional back support device, secured to the body side. The back panel and support device may be filled with padding material such as a gel, foam, rubber, fluid or the like. When the user ties the two straps, the backpack is automatically compressed and moves closer to the user's back The system, operated like a regular two-strap backpack, allows the user to carry heavier loads for a longer period of time with less fatigue. | 02-04-2016 |

20090239316 | METHOD AND SYSTEM TO DYNAMICALLY COMPENSATE FOR PROBE TIP MISALIGNEMENT WHEN TESTING INTEGRATED CIRCUITS - Method for dynamically compensating probe tip misalignment with a semiconductor wafer. The wafer is located on a handler and the wafer is adjusted to a first temperature. Probe tips of an inspection system are moved to a first position centered above pads of a test module on the wafer. The first position is recorded in a memory of the inspection system at the first temperature. The wafer and the probe tips are adjusted to a second temperature while the wafer remains in the inspection system. A second position of the probe tips is recorded in the memory while the probe tips and the wafer are equilibrated at the second temperature. A difference between the first and second position is calculated. Relative positions of the probe tips or the wafer is compensated based on the calculated difference, such that the probe tips are re-centered above the pads at the second temperature. | 09-24-2009 |

20100214927 | METHODS, SYSTEMS, AND COMPUTER PROGRAM PRODUCTS FOR LOAD BALANCED AND SYMMETRIC PATH COMPUTATIONS FOR VoIP TRAFFIC ENGINEERING - The subject matter described herein includes methods, systems, and computer program products for load balanced and symmetric SPF path computations for VoIP traffic engineering. One method includes advertising an output interface cost in a first direction over a first network segment between a source IP device and a destination IP device that is different from an output interface cost in advertised in a second direction over the first network segment. A plurality of available network paths between the source IP device and the destination IP device is identified. A path cost is calculated for each of the available network paths from the source IP device to the destination IP device. Calculating a path cost includes, for paths that include the first network segment, substituting the output interface cost advertised in the first direction with the output interface cost advertised in the second direction. The path costs are ranked based on the calculated costs. A lowest cost path is selected from the ranked paths. Both directions of a media session are assigned to the lowest cost path. | 08-26-2010 |

20160080994 | SYSTEMS AND METHODS OF MANAGING COMMUNICATION ENDPOINTS - In one embodiment, a method includes receiving a trigger to dynamically modify a serving site of a communication endpoint, wherein the communication endpoint is registered to receive digital communication service from a first serving site. The method further includes determining a stored serving-site selection policy applicable to the communication endpoint. The method also includes selecting a second serving site for the communication endpoint based, at least part, on a stored serving-site selection policy. Also, the method includes determining endpoint-configuration requirements of the second serving site. Furthermore, the method includes dynamically generating endpoint configurations that satisfy the endpoint-configuration requirements of the second serving site. Moreover, the method includes writing the generated endpoint configurations to the communication endpoint. Additionally, the method includes causing the communication endpoint to register to receive digital communication service from the second serving site in place of the first serving site. | 03-17-2016 |

20140139866 | Printer control mechanism for a device having a mobile operating system - A table-side hospitality device includes an integral printer mechanism, such as a thermal printer. The device comprises a general purpose processing unit on which a mobile- or embedded-device operating system, such as Android, executes. A control program (the device application) executing on the processing unit facilitates ordering, order management, invoicing and payment. When the application needs to print, it interacts with the printer directly, preferably using the general purpose input-output (GPIO) bus of the processor. In particular, during the print operation, the processor (via the general purpose I/O) outputs, as a set of control signals, a bit-map of the desired graphics (text, images, or the like), and these control signals drive the printer directly without requiring a dedicated micro-controller or OS-specific printer drivers. | 05-22-2014 |
20140192795 | Secure wireless network-based activation for table-side information and point-of-sale devices - A new table-side device is seamlessly and securely integrated to an existing (primary) Wi-Fi network within an operating environment at a restaurant location. The location includes a data management server (DMS) for managing the local operations of devices operating there. The device being installed at the location is auto-configured into the primary Wi-Fi network by being provided with a default Wi-Fi profile that only enables the device to be activated on an activation Wi-Fi network also available at the location. Once the device activates to the Wi-Fi activation network, it requests activation onto the primary Wi-Fi network from a cloud-based data center. The data center requests an activation password from the local DMS. The local DMS generates an activation bundle, which is then returned and eventually instantiated on the device to complete the activation. Once activated, the device updates its Wi-Fi profile to now executed on the primary Wi-Fi network. | 07-10-2014 |
