Title: Railroad car coupler gap analyzer
Inventor: MACE STEPHEN E
IPC: F16P3/14
Filed: 2006-04-12
Abstract: In trains a dragging air hose can snag an object on the tracks and break. A broken air hose can lead to an emergency stop or an accident caused by faulty brakes. The present invention mounts a video camera opposite a lit screen, thereby contrasting the air hose profile against a white screen in all weather and lighting conditions.      Machine vision algorithms locate the air hose in a captured image from a moving train, and compute its lowest point. An alarm condition is sent to a remote location. An optional car gap detector is laser based. It helps align the car gap with the data capture for the camera. Another subsystem can include a car coupler height detection algorithm.

Title: Methods and apparatus for providing a tolerable delay for slotted messages in wireless communication networks
Inventor: ISLAM MUHAMMAD KHALEDUL
IPC: H04L69/14
Filed: 2004-12-07
Abstract: In one illustrative example, a plurality of page message requests for a plurality of mobile devices which operate in a wireless communication network are received. One or more paging slots assigned to the mobile devices are identified for transmitting a plurality of page messages in response to these requests. However, the wireless network refrains from causing a page message for the mobile device associated with a tolerable delay indication to be transmitted within the one or more paging slots when a paging capacity limit of the one or more paging slots is reached. This allows higher priority page messages to be transmitted within the one or more paging slots. The wireless network subsequently causes a page message for the mobile device having the tolerable delay indication to be transmitted within one or more subsequent paging slots within a tolerable delay period corresponding to the tolerable delay indication. The mobile device may transmit the tolerable delay indication to the wireless network in response to identifying a predetermined condition, for example, identifying use of a high capacity power source.

Title: Pull down, push up, shade assembly
Inventor: WU LAWRENCE S
IPC: E06B9/322
Filed: 2004-07-21
Abstract: A collapsible window covering capable of height adjustment, comprising, in combination, an upper elongated support, a lower elongated member that is adjustable up and down, and control lines extending downwardly to suspend said lower elongated member. A primary rotor structure at the upper elongated support entrains the lines. Dual rotary members act on the lines to exert a counterbalancing suspension force on the lines at different window covering height adjusted levels. One dual rotary member exerts tensioning force on the lines and there is an S-shaped spring coupled to the dual rotary member acting to urge the one rotary members in a direction for winding the lines on the one rotary member. The upper elongated support includes a straight channel with a receptacle in the channel in which the dual rotary members and the spring are protectively carried. The channel orients the receptacle so that the lines in the channel remain substantially aligned with the one rotary member in the receptacle.
