A patellar trial and drill guide for use during knee replacement surgery comprising an articular surface member and a fixation peg drill guide. The articular surface member is the exact geometry as the artificial patellar implant, and the drill guide aligns the holes for the fixation pegs of the artificial patellar implant. The patellar trial is placed on the resected patella in the desired position, a patellar clamp is used to temporary fix the patellar trial to the patella. The patella is then returned to its normal position and a trial reduction of the total knee replacement is completed. If the placement and / or size of the patellar trial is unacceptable, the patella is inverted, the patellar trial removed, and a different sized trial or new location is determined. The new patellar trial is secured to the resected patella, and another trial reduction of the total knee replacement is completed. This procedure can be repeated until the patellar trial is the correct size and in the proper location. If the placement of the patella is acceptable, the patella is inverted, the articular surface member removed, fixation peg holes are drilled using the fixation peg holes of the drill guide, and an artificial patellar implant is implanted on the patient's remaining patella.

An instrument for recording and replicating the spatial orientation of a dialable component of an implant relative to a bone engaging component of the implant includes a base assembly for supporting the bone engaging component and a fixture supported on the base assembly for supporting an alignment tool. The alignment tool is configured to engage a portion of the dialable component when the implant is supported by the base assembly. The fixture includes a locking assembly for locking the spatial position of the alignment tool relative to a pre-determined datum on a trial implant. The same instrument can be used to support a final implant and to replicate the spatial position of the alignment tool relative to the same datum on the final implant. The alignment tool can then be used to align the dialable component of the implant. The alignment tool can also constitute an impacting tool so that it can be used to impact the dialable component into locking engagement with the implant using the same instrument.

A system and a method for configuring communication between a source device and a sink device using captured configuration data are described. The source device communicates with a repeater, which modifies received data to facilitate transmission to the sink device, using a communication channel. The communication channel transmits video and / or audio data from the source device to the sink device. An auxiliary communication channel is used to communicate configuration data between the source device and sink device to optimize transmission and receipt of data through the communication channel. The repeater is coupled to the auxiliary communication channel and passively captures configuration data from the auxiliary communication channel. The repeater uses a subset of the captured configuration data (e.g., data rate, voltage swing, pre-emphasis, etc.) to modify how the repeater transmits data to the sink device using the communication channel.

Systems and processes for the duplication of dentures from existing dentures. The interior and exterior of the dentures are scanned and a best fit procedure is used to create a fully digitized denture.

The invention discloses a matching current mirror for converting a current ratio and particularly relates to a current ratio converting current mirror for converting a reference current into an accurate fixed-fold current. The current mirror reduced current reproduction errors and ensures accurate current production. In the current mirror, the output end of an operational amplifier controls the current or voltage of a controlled circuit to change, so that a current or voltage signal generated after the change passes through a load circuit to generate a voltage value equal to that of the voltage at the positive input end of the operational amplifier at the negative input end of the operational amplifier. According to the characteristic that the voltage at the positive input end of the operational amplifier is equal to that at the negative input end of the operational amplifier, the drain voltages of two MOS tubes constituting the current mirror are clamped to be equalized so as to ensure that the drain-source voltages of the two MOS tubes constituting the current mirror are equal. The grid electrodes of the two MOS tubes constituting the current mirror are connected to ensure that the gate-source voltages of the two MOS tubes are equal. Thus, the current reproduction errors are reduced, the current is accurately reproduced, and the matching accuracy of the current mirror is improved.
