Abstract: The system provides analogue electronic sensor means, novel mechanical harness mounting means having adjustment means and provided with remote attached monitor control means for sampling breast surface temperature and means for collecting, storing and displaying these data. The system allows breast temperatures to be measured, with great reliability, for periods of an hour or more at any desired rational sampling rate. Collected breast surface temperature data may then be downloaded into a computer for elaboration using proprietary software. Breast surface temperatures are measured at a specific point during the menstrual cycle, determined by progesterone levels in the urine. The data obtained with the instant invention under these conditions enables an investigator to determine, in women who have not reached the menopause, those who are at risk of developing breast cancer at some time in the future and those who are not at significant risk of developing the disease.

Abstract: A communication system providing telephony communication across combined circuit switched and packet switched networks, such as a telephone network and the Internet, which are connectable to terminals, such as telephones and computers, for selective communication therebetween. The communication system includes a directory object in the packet switched network, multiple gateways between the circuit switched and packet switched networks providing controlled connectivity between those networks, and an interface between the directory object and the gateways. The directory object is preferably provided in hierarchical architecture as a unitary logical object having distributed instances. In addition to the customary address translation capability the directory object polls or communicates with the gateways through the additional interface and provides an intelligent routing function. The directory object is of an enhanced type with access to a storage of customer routing and handling selections.

Abstract: A number of gateway objects interconnect circuit switched and packet switched networks, such as the telephone network and the Internet, for example to enable telephony communication across the combined networks. A directory object coupled to the packet network provides address translation capability, and the directory object polls or communicates with the gateways to provide an intelligent selection of one of the gateway objects, typically for egress to the telephone network. The system also includes an authorization control object. After gateway selection, a calling terminal attempts communication through the gateway object. The gateway object then queries the authorization control object, which instructs the gateway object to proceed only if the requested communication between the calling terminal and the destination terminal is authorized.

Abstract: An internetwork (such as the Internet) telephony system and method incorporating architecture and methodology which facilitates a high degree of scalability. The scalability provides improvement dealing with usage recording, usage pricing, billing account management, and fraud control. The scalability is achieved primarily by bundling of usage recording, pricing, authorization and billing practices in one logical database object which may be physically distributed. A predefined set of network elements are provided access to the database object to obtain authorization for a call along with limitations on the maximum cost or duration of the call for the particular account involved. The database object records usage statistics relating to the completed call, including pricing, and this data is available for virtually immediate billing. The database object provides to customers on a virtual real time basis the customer's usage statistics, including statistics for a call in progress.

Abstract: A laser targeting device for use during surgical procedures provides means for the precise co-axial alignment of a narrow laser beam with an x-ray beam. The device has a case which contains a reflecting mirror mounted at 45.degree. on a low mass assembly. The mirror lies directly in front of a radio-opaque cruciform target. The case is adjustably mounted so that the image of the crosshair target may be accurately centered on the target head. A calibration aid is used to pinpoint the emanation point of the x-ray beam from the source cone of the image intensifier. The angle at which the laser beam strikes the mirror may be varied in two planes. When the crosshair image is centered and the laser beam is directed onto the emanation point the two beams are rendered precisely co-axial. Accurate drilling along the laser beam path without further recourse to x-ray screening is more accurate and eliminates direct exposure of the surgeon to irradiation during orthopedic procedures.

Abstract: A die structure for use in conjunction with a metal working press is provided without the usual large bottom plate member secured to the undersides of the spaced apart parallel members projecting downwardly from the underside of the shoe portion of the die. To permit the plateless die structure to be rollingly transported from place to place along a horizontal support surface, a plurality of specially designed lifter devices are secured to the die parallels and rotatably carry a plurality of roller members. The lifter devices are pneumatically operable and, when actuated, drive the roller members downwardly beyond the common plane in which the bottom sides of the parallels lie to thereby elevate the die structure above a horizontal support surface and rollingly support the die structure thereon. Upon deactivation thereof, the lifter devices permit the undersides of the die parallels to settle back down onto the support surface, thereby stationarily positioning the plateless die structure thereon.
