A sterile suture anchor comprising a body with a distal end, tapered planar side walls and a dome shaped proximal end, a cross section of said body forming a triangular shape with at least one rounded end; and a suture aperture transversely cut through the body being dimensioned to hold at least one suture. An insertion tool for inserting the suture anchor through a substantially cylindrical bore hole in a live human bone and causing the suture anchor to be anchored comprises a handle, a hollow tube secured to the handle and a driver rod slidably mounted in the tube. The driver rod has a distal end defining an angled cam which engages a suture anchor mounted in said tube and rotates the suture anchor into a desired position for insertion into human tissue. A finger driver assembly is mounted on the handle and is secured to the driver and so that movement of the finger driver assembly causes the driver rod to be moved within the hollow tube causing the driver rod cam end to engage the suture anchor and turn the suture anchor in a predetermined orientation for anchoring in the bore hole.

A method for producing an electrical circuit between a flexible circuit board (1) is described, with single-sided access and a metallic contact partner (8), such that the contact partner (8) reaches the metallic conductor strip (4) of the circuit board (1) through an access opening (6) in the unit. The circuit board (1) is thus irradiated with laser light (9) in a region opposite the access opening (6) causing a welded connection between the contact partner (8) and the conductor strip (4) to be formed.

A surge suppressor configured to receive signals from a coaxial line having a signal carrying inner conductor and a grounded outer conductor. The surge suppressor includes an inner conductor exhibiting capacitance and configured to connect to the coaxial line inner conductor, an outer conductor configured to connect to the coaxial line outer conductor and to ground, and an inductor formed of a wire encapsulated in an encapsulating material electrically coupling the inner conductor and the outer conductor. RF signals in the surge suppressor's operating bandwidth pass through the surge suppressor relatively unimpeded while electrical surges will be diverted through the inductor to the outer conductor, and therefore to ground, and possible residual pulses will be blocked from passing through the surge suppressor by the capacitance.

A monolithic antenna element comprises a microstrip patch antenna and a ground plane, with a substrate between the patch antenna and the ground plane. A feeding via extends from the ground plane layer through the substrate to the patch antenna, connecting to the antenna distal from lateral edges of the antenna. A coplanar waveguide (CPW) feed line is formed in the ground plane layer, and interrupts and is electrically distinct from the ground plane. The CPW extends from a lateral edge of the ground layer to the feeding via. The antenna can be flip chip bonded to a CMOS die, reducing cost of millimetre wave transceivers, e.g. 57-64 GHz. The antenna is fabricated using standard PCB technology and a single substrate for the antenna. Antenna arrays can be fabricated. Appropriately designed antenna feeds, flip chip interconnects and antenna shape provide suitably broad antenna bandwidth, with relatively high efficiency.

Chemically-bonded laminated polymer achromatic polarization devices, such as circular polarizers, are disclosed for use in optical disc (e.g., CD / DVD) pickup heads. Chemically-bonded laminated polymer achromatic polarization devices have the benefit of providing stable retardation and optic axis over an extended wavelength range, thereby ensuring orthogonal polarization in double-pass for two or more laser wavelengths. Moreover, the chemically-bonded laminated polymer achromatic polarization devices can be symmetric in construction, such that there is no specific input and output side. This alleviates the need to produce geometries that prohibit inversion of the part when installed in the system. Manufacturing processes that produce chemically-bonded laminated polymer achromatic polarization devices, with high light efficiency, durability and robust performance in a variety of environmental conditions are disclosed.
