摘要:
An ancillary tool for fitting a humeral component of a total or partial elbow prosthesis, comprising a guiding tool (30) for boring a humeral trochlea (T) along a geometric axis (X-X′) of bend of a joint to be equipped with said prosthesis. The guiding tool (30) includes a stirrup element (31) and means (32b, 33b) for securing said stirrup element on the humeral trochlea (T) so that said guiding tool defines a guiding zone that is aligned in the geometric axis of bend for the introduction (F1) of a drill (40), a punch or the like, in the humeral trochlea (T) along said geometric axis of bend. This ancillary tool also comprises at least one stepped template (701, 702, 703) for determining an anterior offset of said geometric axis of bend (X-X′) with respect to a humeral diaphyseal axis (Y-Y′).
摘要:
A humeral component, forming a first articulating surface, and an ulnar component forming a second articulating surface adapted to be disposed around a part of the first articulating surface and to pivot about its longitudinal axis. This ulnar component is provided with structure for mounting a locking element which forms a third articulating surface extending the second and adapted likewise to be disposed around a part of the first surface. These mounting structure comprise guiding structures adapted to cooperate with complementary structure provided on the locking element in order to guide this element in translation with respect to the ulnar component, up to a position where blocking structure provided respectively on the locking element and on the ulnar component may be employed to immobilize this element on this component, these blocking structure being able to be employed only in this position.
摘要:
An ancillary tool (10) comprising a trial humeral trochlea (202) that is representative of an anatomical humeral trochlea when the trial humeral trochlea is in place with respect to corresponding cubital (SC) and/or radial (SR) articular surfaces and a cut-out guide (30) for cutting an ulna (C) and/or a radius (R), wherein the cut-out guide (30) is adapted to be positioned with respect to the trial humeral trochlea (202). The cut-out guide (30) is also adapted to be positioned with respect to an ulna (C) and/or to a radius (R) equipped with the trial humeral trochlea (202).
摘要:
An adaptive telecommunications system for transporting communication traffic over a network comprising a means for transmitting communication traffic between a plurality of devices through a network, monitoring the communication traffic between the plurality of devices, and a adaptively changing the mode of operation either before and/or during a call, based on at least one of instantaneous network changes, connection type characteristics, and type of communication traffic. The devices attached to the network may consist of, for example, a fax machine, phone, mobile phone, public branch network exchange, a computer, or a switch. The traffic traveling across the system, voice, fax, or data, for example, may be compressed and/or restricted based on the type of traffic. The system may fully replace the existing PSTN circuits or may be used for overflow when the existing PSTN circuits are at near or full capacity.
摘要:
An automated telecommunications system includes a first system operable to receive PSTN compatible audio frequency signals, to decode and interpret said incoming signals according to the message format and a modem protocol being used, and transmit digital messages to a second system over a packet data network. Said second system receives and interprets digital messages incoming from the first system, encodes and regenerate outgoing audio frequency signals. The system may be bi-directional and operate over a packet based data network, such as for example an Internet protocol (IP) based network, a satellite based network, or an IP based cable or wireless network. The functionality of said first and second systems may be combined at a single location and operate with a VoIP network to allow modem signals to pass across the VoIP system.

An automated telecommunications backup system includes a first system operable to monitor a primary time division multiplexing (TDM) link on a TDM network for a failure condition and a second system operable to back up at least a portion of the telecommunications traffic of the TDM link over a backup network. The backup network may be a packet based network, an Internet protocol (IP) based network, a satellite based network, or an IP based system over a satellite network. The first system may continuously monitor the primary TDM link and switch the functionality thereof into circuit with the TDM link upon the detection of the failure condition. The second system may compress the telecommunications traffic of the TDM link to transmit a pre-designated number of time slots thereof.

摘要:
A Viterbi decoder is provided with synchronization error detector which detects synchronization errors by monitoring the growth of the path metric associated with a state having itself as a predecessor and to indicate synchronization errors independently of the behavior of metrics associated with other states. The difference between the integral of the selected metric over a certain period of time and the sum of the absolute values of the input encoded data signal is determined and compared to a threshold to indicate whether or not a synchronization error exists.
