摘要:
A telecommunications network includes a mobile switching center (MSC) and a service control point (SCP) communicatively coupled to one another. The SCP is configured to provide the MSC with call routing information for a mobile telephone call received at the MSC so as to direct the call to a wire-line prepaid telephone service provider platform (WPP) in accordance with calling number identification information received at the MSC. The call routing information may include a temporary routing number (TRN) to be used by the MSC to connect the mobile telephone call to the WPP, a carrier identification code, or steering digits prepended to a called number.

This invention relates to a control panel for a vehicle interior. The control panel includes a housing having a recess formed therein. A panel is movably attached to the housing. The panel defines first and second sides, wherein the first side generally defines a first plane which is at an acute angle relative to a plane defined by the second side. The panel is movable between first and second positions, wherein at least a portion of the panel is disposed in the recess when the panel is in the first position. A first control mechanism is mounted on the first side of the panel.

A rear view mirror device for relatively permanent attachment to a transparent support such as an automotive vehicle windshield. The rear view mirror device comprises a housing holding a light reflective member, such as a mirror, permitting a view rearwardly of the device, a pivoted arm extending rearwardly of the housing and a bracket adapted for attachment to the windshield. A bonding layer is located in the bracket and is rigidly adhered thereto. An intermediate member, such as a plastic layer, is incidental the opposite side of the bonding layer. Fracturable pins are integral with the bonding layer and extend into the intermediate member and which fracturable pins have ends which are adapted for attachment to a transparent support such as a windshield. These fracturable pins are constructed such that upon a high shear force applied to the rear view mirrow device and which high shear force is imposed upon the pins, they will fracture, thereby permitting separation of the bracket and from the transparent support. This bracket is also highly effective for relatively permanent attachment of any device to a glass or transparent supporting surface and which must separate therefrom upon application of a high shear force.

A resonant antenna circuit for a radio frequency identification (RFID) reader generates an electrical signal for activating a passive identification tag. The identification tag in turn generates a coded electrical signal that is detected by the reader. The electrical characteristics of the resonant circuit are actively and dynamically altered so that the antenna performs more optimally during the transmit and receive intervals.

A diffractive optical element (DOE) and various methods of producing such a DOE are provided in which a diffractive optical microstructure is formed with encrypted data on at least one side of a transparent substrate or in a layer applied to the substrate. The diffractive optical microstructure when illuminated with collimated light, generates a far field interference pattern corresponding to the encrypted data which may be decrypted with suitable optical detectors and processing equipment.

Systems and methods are described for reading EID tags in difficult to reach locations using a portable RFID reader. In many embodiments, the system includes a portable RFID reader and one or more stationary antenna assemblies. The stationary antenna assemblies typically include a loop antenna in a first location and a ferrite antenna in a second location. EID tags in the reading zone of the loop antenna can be read using the portable RFID reader via an inductive coupling between the resonant antenna in the portable RFID reader and the ferrite antenna in the stationary antenna assembly. One embodiment of the invention includes a portable reader having reader circuitry configured to generate an activation signal, a first resonant antenna, where the first resonant antenna is electrically connected to the reader circuitry, a reader housing containing the reader circuitry and the first resonant antenna, and a stationary antenna assembly having a resonant antenna unit including a housing and a second resonant antenna, a loop antenna unit including a housing and a loop antenna and an electrical connection between the resonant antenna unit and the loop antenna unit. In addition, the first resonant antenna in the portable reader is inductively coupled to the second resonant antenna in the stationary antenna assembly.

Systems and methods are described for adapting a portable RFID reader to create a portable RFID reader assembly that includes an extension antenna. In many embodiments, the extension antenna can be added to increase the reach of the portable RFID reader. The extension antenna is inductively coupled to the portable RFID reader and in many embodiments, the extension antenna is retrofit to an existing portable RFID reader. In other embodiments, a portable RFID reader and one or more extension antennas are produced as part of a set. One embodiment of the invention includes a reader having reader circuitry configured to generate an activation signal, a first antenna, where the first antenna is electrically connected to the reader circuitry, a reader housing containing the reader circuitry, an extension antenna including an elongated housing, a second antenna located at one end of the housing, and a third antenna located at the opposite end of the housing, where the second antenna is electrically connected to the third antenna. In addition, the first antenna and second antenna are inductively coupled.

Methods and systems are provided for acquiring seismic data. An ambient electromagnetic signal having a known time dependence is transmitted for propagation within a survey area. The ambient electromagnetic signal is received at distinct geographic locations with independently operating data acquisition units positioned at the distinct locations. Data representing acoustic signals received from the Earth at the distinct geographic locations are collected with the data acquisition units. The collected acoustic signals for the distinct geographic locations are synchronized by correlating the known time dependence of the propagated electromagnetic signal with time dependencies of the collected acoustic signals.

A load indicating fastener comprising a load indicator, a fastener body, and a securing mechanism retaining the load indicator on the fastener body. The load indicator has integral protuberances struck and partially sheared from the load indicator to project from a face and leave corresponding indentations in an opposite face. The securing mechanism may be a member extending radially outward from the shank of the fastener body, such as a plurality of spaced apart tabs; at least one thread; at least one flare, stake, or form; a step ring; a series of bumps; a knurl; and one or more lobes. Alternative embodiments of the securing mechanism include a key-and-keyhole combination; an interference fit facilitated by a chamfer or by one or more lobes or by shaped surfaces of the fastener body and of the load indicator; one or more tack welded interconnections; and an adhesive patch.
