20110274035 | Routing to the Access Layer to Support Mobility of Internet Protocol Devices - Techniques are provided for seamless integration of wired and wireless functionality packet forwarding in network. A plurality of access switches are provided in each of a plurality of mobility sub-domains that are part of a mobility domain of a network. Each access switch serves one or more Internet Protocol (IP) subnets, each comprising a plurality of IP addresses. An access switch obtains an IP address for a wireless device according to the one or more IP subnets that the access switch serves. The access switch sends an association advertisement message to indicate the IP address of the wireless device and to enable other access switches and routers to compute a path to the wireless device. When a wireless device obtains an IP address, it can keep the same IP address as it roams in the mobility domain. | 11-10-2011 |
20110274036 | Maintaining Point of Presence at Tunneling Endpoint for Roaming Clients in Distributed Wireless Controller System - Techniques are provided to support roaming of wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam within and across mobility sub-domains. When a wireless device roams from one access switch to another access switch, a tunneling endpoint apparatus in the wireless device's home mobility sub-domain is configured to serve as the point of presence for the roamed wireless device. Traffic for the roamed wireless device is tunneled from the access switch where the wireless device has roamed (where it is currently attached) to the tunneling endpoint apparatus. When the wireless device roams across mobility sub-domains, then traffic is tunneled from the access switch where the wireless device is currently attached to the tunneling endpoint apparatus in that mobility sub-domain (called a “foreign” mobility sub-domain) to the tunneling endpoint apparatus in the wireless device's home mobility sub-domain. | 11-10-2011 |
20110274082 | Maintaining Point of Presence at Access Switch for Roaming Clients in Distributed Wireless Controller System - Techniques are provided to enable support of roaming wireless devices in a network such that the wireless devices can keep their Internet Protocol (IP) addresses as they roam across mobility sub-domains. Traffic for a wireless device that roams is tunneled back to the access switch that serves the IP subnet which includes an IP address for the wireless device. Traffic is tunneled back to that access switch for the wireless device when the wireless device roams to another access switch which does not serve the IP subnet for the wireless device in the same mobility sub-domain and when the wireless device roams to a different mobility sub-domain, in which case the traffic is tunneled between tunneling endpoints in the respective mobility sub-domains. | 11-10-2011 |
20120082161 | METHODS AND APPARATUS FOR DATA TRAFFIC OFFLOADING AT A ROUTER - This disclosure relates to a system and method for offloading selected data traffic in logical tunnels to the Internet. The offloading provides another data path for selected data traffic that can relieve the burden on a mobile operator's network, such as the backhaul and core networks. As the proliferation of data rich content and increasingly more capable mobile devices has continued, the amount of data communicated over mobile operator's networks has increased. Upgrading the existing network that was designed for voice calls is not desirable or practical for many mobile operators. This disclosure provides systems and methods for offloading data to the Internet at a router to relieve congestion on the mobile operator's network. | 04-05-2012 |

20140085213 | Force Sensing Using Bottom-Side Force Map - A force sensor incorporated into a touch device, measuring deflection in a device stack, including compressible elements disposed between the device stack and the frame element. When the device stack is deformed, applied force is measured using the compressible elements, using capacitive sensing or strain measurements.

20140085247 | Force Sensing Using Dual-Layer Cover Glass with Gel Adhesive and Capacitive Sensing - A touch device including a force sensor disposed between capacitive sensing structures, so both touch and force sensing occur capacitively using device drivers in rows and columns. A dual-layer cover glass, with gel adhesive separating first and second CG layers, so capacitive sensing between the first and second CG layers can determine both touch locations and applied force. The first and second CG layers include a compressible material having a Poisson's ratio of less than approximately 0.48, the force sensor being embedded therein, or disposed between the first and second CG layers. Applied force is detected using capacitive detection of depression of the first CG layer. Depression is responsive to compressible features smaller than optical wavelengths, so those features are substantially invisible to users. Alternatively, the compressible features may be large enough to be seen by a user, but made substantially invisible through the use of a fluid or other element filling spaces between the features. Such a fluid may have an index of refraction equal to, or nearly equal to, the index of refraction of the compressible features. | 03-27-2014 |

20140268150 | MULTI-SURFACE OPTICAL TRACKING SYSTEM - An optical tracking device that is capable of operation on both glossy and diffuse surfaces includes at least one housing, at least one light source, and at least one sensor. The light source emits light toward a surface on which the housing is moved and the sensor receives the light emitted by the light source after it is reflected off of the surface. The light source is oriented such that the angle of incidence of the emitted light corresponds to Brewster's angle. The sensor may be also oriented such that the angle of reflection of the reflected light corresponds to Brewster's angle. The light emitted by the light source may be polarized to increase the p-polarization of the emitted light and/or the light received by the sensor may be filtered to block s-polarized portions of the reflected light. | 09-18-2014 |
