Title: Method and apparatus to minimize packet loss during active data hard handoff
Inventor: SREY LENA
IPC: H04B7/26
Filed: 2007-01-12
Abstract: A method of hard handoffs begins by establishing a wireless link between a source radio access network (102a) and a mobile station (106). When the mobile station moves into another adjacent radio access network (102b), the present invention detects that handoff of the link from the source to the target is necessary. Additional data is not sent to the mobile station from the source radio access network. The data that has not been received by the mobile station is stored or buffered. A disconnect message is received by the source and a connect message is received by the target so that an active handoff is achieved between the source and the target. When the active handoff procedure is complete the data that was buffered by the source BTS as not being received by the mobile station is then sent to the active target cell such that data and packet loss is reduced.

Title: Reinforced optical films
Inventor: OUDERKIRK ANDREW J
IPC: G02F1/1335
Filed: 2007-03-28
Abstract: Optical films having structured surfaces are used, inter alia, for managing the propagation of light within a display. As displays become larger, it becomes more important that the film be reinforced so as to maintain rigidity. An optical film of the invention has a first layer comprising inorganic fibers embedded within a polymer matrix. A second layer having a structured surface, for providing an optical function to light passing therethrough, is attached to the first layer. The film may have various beneficial optical properties, for example, light that propagates substantially perpendicularly through the first layer may be subject to no more than a certain level of haze or light incident on the film may be subject to a minimum value of brightness gain. Various methods of manufacturing the films are described. ® KIPO & WIPO 2009

Title: Method of detecting malfunction of restriction mechanism downstream side valve of pressure flow control device
Inventor: NAGASE MASAAKI
IPC: G01F1/00
Filed: 2007-06-13
Abstract: There has been a problem that it is impossible to judge the opening of a restriction mechanism downstream side valve of any conventional pressure flow control device on the basis of presence of the upstream output signal because of the structure of the pressure flow control device. According to the invention, the opening of a restriction mechanism downstream side valve can be judged from the variation state of the flow output signal when the pressure flow control service operates. The restriction mechanism downstream side valve of the pressure flow control device is opened, the flow set value Qe input into the pressure flow control device is varied, and the variation V of the flow output signal Qo from the pressure control device while the flow set value Qe is varied is detected. When the variation V of the flow output signal Qo is equal to or higher than a specified value, the opening of the restriction mechanism downstream side valve is judged to be normal. When the variation V is less than the specified value, the opening is judged to be abnormal.

Abstract: Systems and methods are disclosed that determine whether incoming calls are in a home local calling area (LCA) in a wireless network. One embodiment comprises an LCA determination system (300) that includes a processing system (302) and a mapping data structure (304). The mapping data structure (304) includes a plurality of entries that map a switch/cell identifier (e.g., an MSC/cellsiteID) to a set of LCA identifiers. For a call in a wireless network, the processing system (302) receives a switch/cell identifier, masks the sector identifier from the switch/cell identifier, and searches the mapping data structure (304) based on the masked switch/cell identifier to identify an associated set of LCA identifiers. The processing system (302) then compares the set of LCA identifiers to a subscriber profile to determine if an LCA identifier matches. If there is a match, then the processing system (302) determines that the call is in a home LCA.
