Abstract: The described invention provides a method and system for allowing subscribers of a telematics service provider (TSP) to make hands-free phone calls within their vehicles through a telematics unit over a network or hardware-based pre-pay system, wherein the telematics unit or a wireless network provider associated with the TSP controls the ingoing and outgoing hands-free calling (HFC) processes. The wireless network provider, through its system at a remote call center or through the telematics unit, may determine whether the subscriber has subscribed to the TSP's HFC service, whether the subscriber has a sufficient remaining balance to initiate, receive or continue a call, and whether a user of the telematics unit is “roaming.” When a user attempts to make or receive a call through the telematics unit, the wireless network provider or the telematics unit may handle the incoming or outgoing call processing, and may further provide subscriber account balance notifications to the user.

Abstract: The described method and system provide for over-the-air configuration of a telematics-equipped vehicle by wireless carriers and telematics service providers (TSPs). Regardless of whether a telematics-equipped vehicle has been provisioned for cellular service or not, the TSP and wireless carrier may control undesirable location updating from the vehicle, for example, by setting certain triggers or conditions upon the telematics unit before processing location updates provided by the telematics unit. These triggers or conditions may also be programmed into the telematics unit, whether through an OTA configuration session, or pre-loaded during manufacture. The TSP or wireless carrier may conduct OTA configuration sessions with the telematics unit to provision the telematics unit for cellular service, or provide the telematics unit with software or firmware updates.

Abstract: A system and method of managing communications with a vehicle telematics unit includes determining that a data transmission to a vehicle telematics unit over a wireless carrier system has failed; automatically performing a network registration check with the wireless carrier system to determine the registration status of the vehicle telematics unit based on the data transmission failure; and deciding whether to re-transmit the data to the vehicle based on the results of the network registration check.

Abstract: Methods for providing emergency service to a mobile vehicle are disclosed herein. One method involves monitoring a network country code broadcast from a communications network provider and comparing the network country code with a list of country codes stored in the telematics unit. This method further includes determining where to direct an emergency call by the telematics unit based on the comparing. Another method involves notifying a telematics service provider of a need for emergency services and, in response to a denial for the services, monitoring the network country code broadcast and comparing the network country code with the list of country codes to determine where to direct the emergency call. Yet another method involves notifying a telematics service provider of a need for emergency services and, in response to a denial for the services, automatically notifying another service provider of the same.

Abstract: An automated method for remotely changing the mobile number (MDN or MIN) of a wireless communications device, such as a vehicle communications device capable of making hands-free calls. Generally, some wireless carriers do not allow multiple mobile numbers to be simultaneously activated to a single wireless communications device. Therefore, when a mobile number change request is made, the automated method determines what type of process is most appropriate for that change: an indirect change process that uses at least three mobile numbers (current, intermediate, and target numbers) and addresses the above-mentioned wireless carrier limitations, or a direct change process that uses only two mobile numbers (current and target numbers). In either case, a wireless data link is established between a call center and the vehicle communications device so that the remote number change can be performed.

Abstract: A method and apparatus for assigning a mobile dialing number (MDN) to a wireless mobile communication device (MCD), for providing local call access to the MCD from a base address for the MCD, by first selecting a wireless rate center encompassing the base address and having an MDN providing local call access to the MCD from the base address for the MCD, and then assigning the MDN to the MCD, for providing local calling access to the MCD from the base address for the MCD. A database defines geographic boundaries of a plurality of wireless rate centers, including the wireless rate center encompassing the base address and having the MDN providing local call access to the MCD from the base address.

Abstract: A caster arrangement for cabinets used on access or raised floors of a computer room or the like. The caster arrangement allows for a small, heavy cabinet to be situated on the panels of the access floor without applying concentrated or ultimate loads on the panels that may exceed the design characteristics of the panel and access floor. The caster arrangement allows for at most three casters to apply load to a given panel while the cabinet is being moved or has an arbitrary orientation.

Abstract: A recessed hinge is disclosed that allows a door to open to an angle greater than 90 degrees. The hinge has a hinge pin with two free ends so that the hinge is also fully reversible, for use either on the right hand or left of an enclosure. The hinge also provides for simplified horizontal adjustment by having oval mounting holes for attaching the hinge to the enclosure, and the hinge provides for vertical adjustment by disposing one or more washers on the free end of the hinge pin. Vertical adjustment of the door as well as door removal may be accomplished without tools.

Abstract: A system of ancillary cabinet for use with an uninterruptible power source (UPS) is disclosed. The ancillary cabinets have modular and reversible features that facilitate the installation of an uninterruptible power supply. The frames for the ancillary cabinets use a galvanized riveted frame design. The frames use pop rivets to allow the units to be shipped flat and assembled easily in the field. The overall size of the ancillary cabinets are consistent with the dimensions of a UPS cabinet. Specifically, the depth and height of the ancillary cabinets match the UPS. Also, the overall cabinet design matches the style, color, and texture of the UPS cabinet. The ancillary cabinets may be bolted to each other and/or the UPS cabinet to form a specific UPS system. The cabinets are serviceable by front access. An inter-cabinet wiring trough (wiring access) in the ancillary cabinets matches up with the UPS.

Abstract: A radio frequency bridge, useful for measuring complex values of an unknown impedance or associated complex reflection coefficient and VSWR value, which comprises an rf source, a novel asymmetrical bridge, a measuring device (comprising two logarithmic amplifiers, a difference amplifier and a phase detector), a computing device and a display or interface device. The complex impedance may be any two terminals of a general N-port network not to exclude an antenna with or without feed-line. The invention is more accurate than prior art when measuring complex impedance values having magnitudes from approximately five ohms to an upper value limited only by the dynamic range of the logarithmic amplifiers, normally greater than 4000 ohms. It has the great advantage of maintaining constant measuring accuracy over a wide measuring range and can be designed to operate over very wide bandwidths.
