Abstract: A bone fixation member can be configured to secure first and second bone segments of a target bone together in a compressed approximated position. The bone fixation member can include a strap made of a first material, a locking head extending from a proximal end of the strap, and a leader portion extending from a distal end of the strap. The locking head can have a housing and a strap receiving slot that extends through the housing, slot is configured to receive a distal end of the strap. The housing can be tapered such that a distal end of the housing has a thickness that is greater than the thickness of a proximal end of the housing. The leader portion can be configured to be more flexible than the strap. The leader portion can be made of a second material that is different than the first material.

Abstract: An implant assembly can include an implant configured to be coupled to at least one bone part. The implant can include an implant body that defines at least one unsmooth surface. The assembly can further include a cap configured to be coupled to the implant body such that the cap overlies the at least one unsmooth surface. The cap can include a shell that defines a cavity that is configured to receive at least a portion of the implant body such that the shell flexes relative to the implant body as the cavity receives the at least a portion of the implant body to thereby couple the cap to the implant. The cap defines an outer surface that is curved.

Abstract: Described herein is a system and method of emulating characteristics of an output signal of a first analog-to-digital converter by a second analog-to-digital converter employing signal processing. A signal processing module may receive a digital signal from the first analog-to-digital converter and alter the digital signal to define an altered digital signal such that the altered digital signal emulates a second digital signal that is characteristic of the second analog-to-digital converter, the second analog-to-digital converter differing from the first analog-to-digital converter.

Abstract: A sighting mechanism for a firearm, including two video cameras, a video screen, a digital sighting distance meter, a sensor for measuring environment, cartridge and/or weapon parameters, a biometric sensor, a memory module for biometric data and/or munitions data and a digital computer. The video cameras are arranged parallel to each other to capture the target sighting field. The computer has video inputs and an image processing unit enabling the video image data to be superimposed in real time in a pixel precise manner in relation to the target field on the screen. The computer includes a ballistic computer which enables the target image to reproduce on the screen. A graticule arranged on the screen can be positioned automatically and in real time according to the incoming data, such that the position of the graticule in the target field corresponds to a real projectile point of impact.

Abstract: Digital amplifier for amplifying a digital input signal, comprising a digital modulator for converting the digital input signal into an amplitude-discrete and temporally analogue signal, comprising an analogue error correction circuit which modulates the pulse widths of the amplitude-discrete and temporally analogue signal in dependence on an analogue error signal, comprising a power switching stage, the input of which receives the signal modulated by the error correction circuit and which delivers the modulated signal amplified at an output and comprising an analogue feedback circuit which, in dependence on the output signal of the digital modulator and on the output signal of the power switching stage, generates the analogue error signal for adjusting the analogue error correction circuit.

Abstract: The invention relates to an apparatus for fixing a ligament, which comprises a bone-anchoring element having a proximal end and a distal end which has a bore running in the longitudinal direction, and which comprises a clamping sleeve having a proximal end and a distal end, which clamping sleeve can be accommodated in the bore. The clamping sleeve is radially expandable, with the result that the ligament can be fixed between the clamping sleeve and the bore of the bone-anchoring element.
