Abstract: The present invention provides methods, devices, and systems for modeling optimized flow path assignments for signaling and media traffic in a network connected population of telecommunications systems. More specifically, optimum inter- and intra-system flow path assignments can be determined based on, for example, a virtual simulation of the telecommunications system. The optimization criteria may include flow path properties, flow path length, flow path element degradation of voice quality, monetary cost of flow path element usage, and flow path element contribution to overall system availability.

Abstract: The present invention provides methods, devices, and systems for determining the availability of at least a part of a communications network in the context of alternate routing. Moreover, the present invention is adapted to consider network flow variations based on device outages all while accounting for the actual probability associated with various re-routing scenarios.

Abstract: A feature of the present invention is it is adaptable to any pre-existing storm catch basin system. Another feature of the present invention is that it permits empirical analysis and verification of the draw down rate. Another feature is the present invention can be adjusted or modified to increase or decrease the rate of draw down after it has been installed to insure regulatory conditions are precisely met without difficulty. Changes in future regulatory draw down rates can be easily implemented. A flow restriction device has an orifice plate, the orifice plate having a frontal surface area A and at least one opening for the passage of fluid of an area Oa, wherein Oa is less than A. The flow restriction device may also employ a screen debris plate, the screen debris plate having a plurality of spaced openings for the passage of fluid; the sum area of the openings being ?Osp wherein ?Osp is greater than Oa.

Abstract: A brake controller, for controlling the brakes of a towed vehicle, having a control module and a power module is provided. The control module is mounted in the cab of a vehicle used for towing, in such a manner that it can be easily seen and accessed by the driver. The control module is provided with an accelerometer, which can read acceleration forces in at least two axes, and a microprocessor which polls the accelerometer and sends braking information to the power module. The control module is also provided with a gain control, to adjust the amount of brake force information, a manual braking lever and a display panel. The power module, which may be mounted in a convenient location, preferably on the towed vehicle, receives the braking information from the control module and secures power from the towed vehicle to engage its brakes.

Abstract: This invention utilizes transparent plastic probes or a single multi-level probe, immersed in a fuel tank to detect fuel level. A light source and light sensing element is incorporated with the level probe so that as liquid touches the immersed end of the probe a change in reflective light occurs which results in a change in the electrical output of each light sensing device. The resulting signals from the light sensing devices are converted for use in fuel level gagging and for use by flight computers and similar devices. The invention also includes corporation of static electricity suppressing. coatings and an encasement cage to reduce the effect of fuel foam and fuel level fluctuations to due movement of fuel in the tank resulting from vehicle movement.

Abstract: This invention uses the change visual appearance on one end of a transparent probe when the opposite end contacts the surface of the liquid to be measured. A flexible fiber optic device is used to allow remote viewing or sensing with electronic sensors. The device includes the use of multiple probe levels to allow indication of a range of liquid levels. Optional use of a light source in low light conditions is also provided.

Abstract: A hierarchical database reporting and updating system is disclosed. The invention makes unique use of bit vectors to represent the relationship between various data items to enable the system to provide powerful data analysis functions. The data structure allows users to change values which represent intermediate or grand summary levels. Such changes are prorated across all lower level data items which make up the intermediate or grand summary level. The invention also allows for the graphical representation of data. Users may modify these graphical representations and the system will update the underlying data.

Abstract: A rigidly constructed tonneau cover, hatch and seat assembly is disclosed for converting the truck bed of a standard pickup truck into an expanded seating capacity outside of the truck cab. The assembly is comprised of a generally rectangular tonneau cover for covering the bed portion of the pickup truck. This cover includes a hingably openable back portion that functions like a trunk to allow easy access to the truck bed. This portion can be locked so the contents of the truck bed are secured. The tonneau cover also has a removable hatch that provides access and protection for a rotatably mounted windshield, and for persons in one or more seats slidably mounted on the truck bed. In the closed position, the hatch protects the truck bed, seats, and added cargo, etc., from damage and undesired access. When the hatch is detached from the tonneau cover, it may be positioned vertically behind the seats and projects above the surface of the tonneau cover.

Abstract: A pressure-actuated head for detonating a gun for perforating a well bore is suspended on a tubing string for lowering down the well. The head includes a detonator pin biased towards a detonator but restrained until detonation is required. Detonation is effected by causing or allowing a pressure differential to develop across a piston. Fluid communication between chambers on respective sides of the piston is via a pressure control system which allows the pressure differential to develop over a period of time.
