Abstract: The present invention relates to a mixed material bone screw. The bone screw comprises a distal end made of a biocompatible material and a proximal end made from a stronger material to resist stripping of the bone screw during its insertion or removal from a bone. In another embodiment, the mixed material bone screw is cannulated, wherein the bone screw has a bore forming a central channel connected to a plurality of sideward channels for delivering bone cement or other substances into the bone surrounding the bone screw.

Abstract: A surgical screw system and device with a screw head having multiple insertion engagement features. The screw preferably a tubular body having a first end and a closed second end, wherein the head configured to engage with a diiver to advance the screw into the bone. The head of the screw has at least two different insertion features, such as a cross shaped insertion feature and a hexalobe shaped insertion. The screw can be advanced or removed via a driver that mates with the cross shaped or the hexalobe shaped insertion features.

Abstract: A method of creating a template for presenting content within a document. The method includes defining a plurality of components, each including at least one content region and at least one of a frame, a template perimeter and an object. A number of links are then defined between the components, each link representing a respective spatial relationship. A processing system is then responsive to the template to populate the content region with content, generate a representation of each component and position the representation of each component in the document using the defined links to control the relative spatial positioning of the components.

Abstract: A portable brewing device is provided for brewing a hot beverage such as espresso that includes a compressed gas container communicating with a pressure regulator that is configured to control the pressure of gas released from the compressed gas container. A release switch is configured to communicate with pressure regulator and configured to release pressure controlled gas when actuated by a user. A water vessel is configured to receive the pressure controlled gas when the switch is actuated by a user. A mixing vessel can hold a brew substance and is configured to communicate with the water vessel and also configured to receive water from the water vessel to pass through the brew substance when pressure is released from the gas container through the pressure regulator. An outlet is configured to release a brewed product produced from water flowing through the brew substance contained in the mixing vessel when brewing.

Abstract: An LVDS (Low Voltage Differential Signal) driver circuit having low sensitivity to fabrication process variation, power supply noise voltage variation, and operating temperature variation (PVT). The LVDS driver circuit includes a predriver having an input coupled to an internal circuit. The predriver is coupled to a current source. The current source includes a first resistance and is configured to produce a reference current through the first resistance. The reference current is coupled to the predriver to control an output swing of the predriver, the output swing determined by a ratio of the first resistance and a second resistance in the predriver. The ratio of the first and second resistance is such that the output swing is constant across PVT. An output driver is coupled to the predriver to receive the output swing. The output driver has an output for coupling an output signal to an external circuit.
