Abstract: A modular pedicle screw includes a head assembly configured to “pop” or “snap” on a fastener of the screw. The head assembly includes a collet. The collet includes a friction ring for frictionally engaging a head of the fastener. The collet includes ring portions defining a split ring for receiving the head of the fastener. The ring portions are movable axially and radially relative to a rod coupler of the screw to enable attachment and detachment of the head assembly on the head of the fastener. The collet is movable axially relative to a saddle of the screw. The saddle and collet are coupled to one another by a tongue of the collet being received in a groove of the saddle.

Abstract: One or more multi-stage optimization iterations are performed with respect to a compression algorithm. A given iteration comprises a first stage in which hyper-parameters of a perceptual quality algorithm are tuned independently of the compression algorithm. A second stage of the iteration comprises tuning hyper-parameters of the compression algorithm using a set of perceptual quality scores generated by the tuned perceptual quality algorithm. The final stage of the iteration comprises performing a compression quality evaluation test on the tuned compression algorithm.

Abstract: Respective labels indicative of compression-related quality degradation for a set of media object tuples which meet a divergence criterion are obtained; each tuple comprises a reference media object and a pair of corresponding compressed media object versions. Pairs of training records for a machine learning model are generated using the labeled media object tuples and multiple perceptual quality algorithms, with each training record comprising respective perceived quality degradation scores generated by each of the multiple algorithms for a given compressed media object of a tuple. A machine learning model is trained, using the record pairs, to predict quality degradation scores for compressed media objects.

Abstract: A bone screw assembly includes a fastener including a shaft and a head disposed on the shaft. The fastener is configured to be anchored within a subject's bone. A receiving assembly is configured to be movably mounted on the head of the fastener. The receiving assembly includes a receiver disposable around at least a portion of the head of the fastener and defining a channel for receiving a rod member therein. A retaining ring is disposed within the receiver for holding the head of the fastener in the receiver. An insert is disposed in the receiver above the retaining ring. A saddle is disposed in the receiver above the insert. The saddle defines a cradle for seating the rod member in the receiver.

Abstract: A key model identification and feedback system includes a key identification housing, a master key receiving aperture, a master key identifier, a processor in communication with the master key identifier, and a feedback module. The processor is configured to access a database defining a plurality of known key models, compare the physical characteristics of the master key with physical characteristics of the known key models in the database to identify a model of the master key, and communicate the model of the master key to the feedback module coupled to the key identification housing. The feedback module, responsive to the communication from the processor, outputs an indication of the model of the master key and directions to a location remote from the key identification housing where a key blank having the same model of the master key is available for duplicating the master key.

Abstract: A method for controlling medical examinations by means of a patient communication system and includes connecting a patient device to a clinic server unit, and exchanging examination information between the patient device and the clinic server unit. The exchange of examination information can include a retrieval of examination information from the clinic server unit by means of the patient device, a retrieval of a calendar entry, and a retrieval of patient information.

Abstract: A key duplication system may include a housing, a key blank receiving aperture, a cutter and a clamp adjacent to the receiving aperture, wherein the key blank is guided to a predetermined position in relation to the cutter through engagement of a carrier with the housing. A method of aligning a key blank blade with a key blank carrier in relation to a cutter may include guiding a key blade into a cutting position through contact with a key blade receiving aperture, securing at least a portion of the carrier with a clamp, cutting a key bit pattern into the key blank blade and releasing the key blank.

Abstract: Implementations of key blank carriers or key blanks with a standard reference features may include alignment features on a key blank head, key blank tip, a key blank carrier coupled to a key blank sleeve and/or a key blank sleeve, and any feature directly attached to any portion of the key that may be used for referencing in the key duplication system, or any combination of these. The standard reference features may allow any key blank brand model to interface with the machine so as to consistently align each key, regardless of its make and model, for cutting in a universally configured key blank clamp that is clamped to reduce the movement of the key blank during duplication cutting.

Abstract: A key duplication system comprising a key duplication housing wherein at least one key receiving aperture on a first side of the housing sized to receive a key blade and at least one key clamp adjacent to the at least one key receiving aperture, the clamp comprising a first clamp arm with a surface topography corresponding to a first key blade surface topography and a second clamp arm with a surface topography corresponding to a second key blade different from the first key blade.

The planning unit is connected with the at least one medical imaging apparatus. At least one input parameter of a database of the planning unit and at least one input parameter of a database of a subset of the at least one medical imaging apparatus are detected. The database of the planning unit and the database of the subset of the at least one medical imaging apparatus are filtered depending on the at least one detected input parameter. At least one item of output information is determined that includes a selection from medical imaging apparatuses available for the examination of the examination subject.

Abstract: In a finding system, a control system and a computer-implemented method to assess medical images, within the scope of a finding workflow a control module can be activated via which the user can enter control data at the finding system. The control data are automatically converted into control commands, which are transmitted to the acquisition system for execution. The acquisition system is expanded by an expansion module in order to transmit process data and status data to the finding system.
