摘要:
The head plate has a rectangular body with a central portion. The connecting portion of the flexible hinge part is integral with the central portion or the central portion is provided with a recess or slot into which the connecting portion is received. The upper and lower surfaces of the central portion of the body are substantially continuous and uninterrupted so as to provide maximum surface area for bonding to the casting material layers. The upper and lower surfaces may be provided with teeth or splines to increase the area of the bonding surfaces. In one embodiment, the head plate is provided with parallel spaced grooves on either side of the central portion to permit the head plate to move accurately to conform to the contours of the body of the patient.

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 an authorization and account control object in the packet switched network, multiple gateways between the circuit switched and packet switched networks providing controlled connectivity between those networks, and an information retrieval object in the packet switched network, wherein the authorization and account control object maintains a substantially real time record of user accounts and usage, and the information and retrieval object provides substantially real time retrieval of selected information from the authorization and account control object. The retrieval object provides on demand to terminals which provide authentication for access to an identified account information regarding that account. The information regarding the account is substantially real time information including information with respect to communications in progress which are chargeable to the account which has been authenticated. The authorization and account control object is preferably a unitary logical object having distributed instances thereof handling multitudinous accounts of widely separated terminals. The retrieval object provides isolation of the authorization and account control object permitting simultaneous multitasking by the authorization and account control object and the retrieval object respectively.

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. The operation proceeds in the following manner. Each Internet telephone service subscriber will have at least one billing and authorization account maintained in a database on the Internet. During set-up of a call, the hop-off gateway will obtain identification and password information from the caller. The gateway then communicates with the database to determine if the call is authorized and to negotiate the overall billing algorithm. When the call if finished, the gateway will report usage data to the database for billing purposes.
摘要:
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 provides an architecture and methodology for handling resource allocation across carriers or service providers, settlements between carriers and service providers, usage accounting across carriers and service providers, and usage allocation among carriers or service providers. A first provider of packet switched services controls a directory of addresses of gateways between the packet switched and data switched networks, and an authentication database of account data. A second provider of packet switched services controls a multiplicity of the gateways and a database of addresses of authentication databases.

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.
摘要:
A limb brace or immobilizer having at least two relatively rigid support arms extending medially and laterally along opposite sides of a wearer's limb, each support arm having a limb-contacting plate of arcuate cross-sectional configuration and a traction plate connected to or formed integrally with the limb-contacting plate. Each traction plate has a pair of wing portions extending anteriorly and posteriorly in relation to the limb-support arm and spaced outwardly from the limb-contacting plate, with the span of the wing portions being substantially less than the anterior-posterior dimensions of the associated limb-contacting plate. Attachment straps are adjustably secured to the wing portions and join corresponding wing portions of the traction plates on opposite sides of a wearer's limb to secure the assembly in limb-bracing or limb-immobilizing condition.

An orthopaedic brace having an adjustable control mechanism for controlling in a continuously variable manner the limits of pivotal movement of a body support member. The mechanism includes a threaded guide rod with a longitudinal slot, a collar slidably carried by the rod and equipped with an insert element projecting into the slot for preventing relative rotation of the collar and rod, and a pair of stop members disposed on opposite sides of the collar for controlling the extent of the collar's sliding movement. At least one of the stop members is in the form of a nut threadedly mounted upon the rod.

The catheter includes an inner tubular member and an outer sleeve member into which the inner tubular member is freely movably received. The inner tubular member has a section with calibrated markings. The calibrated section is spaced from the end adapted to be received in the urethra, by a distance equal to the length of the outer sleeve member. The outer sleeve member has an outwardly flared end adapted to be situated adjacent the external urethral meatus. The non-flared end of the sleeve member is used as a pointer against the calibrated markings to determine the length of the urethra.
