Abstract:
The location of a wireless mobile device may be estimated using, at least in part, one or more pre-existing Network Measurement Reports (“NMRs”) which include calibration data for a number of locations within a geographic region. The calibration data for these locations is gathered and analyzed so that particular grid points within the geographic region can be determined and associated with a particular set or sets of calibration data from, for example, one or more NMRs. Received signal level measurements reported by a mobile device for which a location estimate is to be determined may be compared with the data associated with the various grid points to estimate the location of the mobile device.
Abstract:
A method of modifying calibration data used to geo-locate a mobile station located in an indoor environment is disclosed. When a mobile station is located indoors, the signal strength of signals received and/or transmitted by the mobile station have the tendency to be lower than the strength of the signals received by a mobile station located outdoors. As a result of these lower signal strengths, geo-location efforts which rely on signal strengths may result in unsatisfactory location accuracy. Modifying pre-existing calibration data obtained outdoors may provide a way to simulate indoor calibration data characteristics.
Abstract:
The coupled building wire of the present invention comprises a first length of non-face metallic cable having a top surface and a bottom surface and a second length non-metallic cable having a top surface and a bottom surface, wherein the bottom surface of the first length of non-metallic cable is coupled to the top surface of the second length of non-metallic cable. The first length of non-metallic cable comprising at least one circuit conductor having a first gauge. The second length of non-metallic cable comprises at least one circuit conductor having a second gauge. The first gauge of the at least one circuit conductor of the first length of non-metallic cable may be substantially equal or unequal to the second gauge of the at least one circuit conductor of the second length of non-metallic cable.

Abstract:
The instant disclosure generally relates to a method and apparatus for determining path loss by combining geolocation with interference suppression. In one embodiment, the disclosure relates to a method for determining a path loss value between a receiver at a first location and a wireless mobile device at a second location. The method includes the steps of: (a) locating the mobile device at the second location and (b) at the receiver: (i) receiving a first signal transmitted by the mobile device at the second location; (ii) determining a received signal level of the first signal; (iii) receiving a second signal comprising data from which a transmitted signal level of the mobile device at the second location can be determined; and (iv) determining from the first and second signals the path loss value between the receiver and the mobile device at the second location.
Abstract:
The present invention includes a cable having reduced surface friction and the method of manufacture thereof including steps in which a conductor wire is coated with a first plastic material, optionally coated with a second plastic material and the coated conductor wire then cooled, and includes a step in which a lubricating material is applied to the surface of the cooled, coated cable. The cable includes at least one conductor core and at least one coating of plastic material and incorporates a lubricating material on the exterior coating. The equipment for the manufacturing of the electrical cable includes a reel for supplying a conductor wire to an extruding head, which is connected to tanks containing plastic materials for coating the conducting wire, a reel for taking up the cable, and a device for the application of a lubricating material onto the surface of the cable.
Abstract:
A method is described that enables a system to estimate the individual times of arrival of multi-path signals components in a received signal while blind to the particular angular response characteristics of an antenna array. Additionally, a system is described that estimate the impulse response of the modulation channel. The impulse response is used to generate impulse response estimates for all multi-path signal components without reference to the actual angle of arrival of the signal. The impulse response for the multi-path constituents are directly associated with the time delays on each path, providing delay estimates for each path.
Abstract:
A novel system and method for a network overlay geolocation system operating in a host wireless communication system with repeaters (350a, 350b) is disclosed. Embodiments of the novel system and method enable the geolocation system to determine if signals being received by the geolocation system arrive directly from a target mobile appliance or if the signals are passing through a repeater (350a, 350b) and therefore are subject to a known time delay. Embodiments of the novel system and method provide a more accurate geolocation of mobiles served by repeater stations than capable in the prior art.
Abstract:
Methods and systems are provided for generating colorized previews of selected document templates. Upon selection of a desired color scheme, each document template represented by a collection of displayed document template previews is colorized according to a user-selected color scheme to provide the user with a preview of the collection of document templates colorized according to the user's desired color scheme prior to selection of one of the displayed templates for actual use. The colorized document templates are converted to bitmap format and are displayed to the user to allow the user to select a particular template colorized according to the user's selected color scheme.
Abstract:
Systems, kits, and methods for establishing vascular access are described. A system typically includes a radially expandable sleeve, a dilator, and a guidewire. The methods comprise positioning the guidewire through an initial tissue tract, passing the radially expandable sleeve over the guidewire through the tissue tract to a target blood vessel, and thereafter passing the dilator over the guidewire and through the radially expandable sleeve to effect radial expansion of the sleeve. Use of the sleeve reduces the risk of injuring tissue surrounding the tissue tract by lessening the axial forces imparted to the tissue. Kits comprise at least the radially expandable sleeve together with instructions for use.
