20150217105 | Catheter Coupling - A catheter coupling has a tubing and two jaws extending in the longitudinal direction of the tubing which form a channel having an orifice to accommodate an end section of a catheter when the jaws abut against each other. The jaws are interconnected at a respective jaw end via a jaw joint having a joint axis extending transversely to the tubing. The other jaw end is in each case provided with a snap-in locking member and a counter snap-in locking member, respectively, interacting therewith to form a snap-in locking arrangement. In the engagement position, the tubing is deformed by at least one jaw deformation component to securely accommodate the catheter end section. The catheter coupling has at least one inspection window in a base body. The inspection window allows a stop in the tubing for the end section of the catheter to be visually inspected. As a result, a catheter coupling is obtained which prevents an end section of the catheter from being introduced into the tubing if said end section is too short. | 08-06-2015 |

20100187574 | Memory Cell For Modification of Revision Identifier In An Integrated Circuit Chip - A memory cell for reducing the cost and complexity of modifying a revision identifier (ID) or default register values associated with an integrated circuit (IC) chip, and a method for manufacturing the same. The cell, which may be termed a “Meta-Memory Cell” (MMCEL), is implemented on metal layers only and utilizes a dual parallel metal ladder structure that traverses and covers each metal and via layer from the bottom to the top of the metal layer structure of the chip. One of the metal ladders is connected to a power supply at the bottom metal layer, corresponding to a logic 1, and another metal ladder is connected to ground at the bottom metal layer, corresponding to a logic 0. The output of the MMCEL can thus be inverted at any metal or via layer and can be inverted as often as required. Significant cost savings are achieved because a revision ID or default register bits may be modified by altering only those metal layers where design changes are necessary. | 07-29-2010 |
20130043916 | Wave Clocking - Embodiments provide systems and methods for dynamically regulating the clock frequency of an integrated circuit (IC) based on the IC supply voltage. By doing so, the clock frequency is no longer constrained by a worst-case voltage level, and a higher effective clock frequency can be supported, increasing the IC performance. Embodiments include a wave clocking system which uses a plurality of delay chains configured to match substantially the delays of respective logic paths of the IC. As the delays of the logic paths vary with supply voltage and temperature changes, the delay chains matched to the logic paths experience substantially similar changes and are used to regulate the clock frequency of the IC. | 02-21-2013 |

A Power Management Unit (PMU) can monitor aging, temperature, and increased load on the processor cores. The PMU instructs the processor to take action such that aging, temperature, and/or increased load are approximately evenly distributed across the processor cores, so that the processor can continue to efficiently process instructions. | 02-21-2013 |
20140214191 | Adaptive Integrated Circuit to Optimize Power and Performance Across Process Variations - An integrated circuit is disclosed that measures and/or monitors a substrate parameter. An actual value of the substrate parameter can vary from its expected value as a result of characteristics of the integrated circuit and/or characteristics of an environment surrounding the integrated circuit. The integrated circuit classifies the semiconductor substrate upon which it is fabricated as being a fast semiconductor substrate or a slow semiconductor substrate based upon the substrate parameter. The integrated circuit operates in a fast-substrate mode of operation when the semiconductor substrate is classified as being a fast semiconductor substrate to adjust an operational parameter to compensate for the fast semiconductor substrate or in a slow-substrate mode of operation when the semiconductor substrate is classified as being a slow semiconductor substrate to adjust the operational parameter to compensate for the slow semiconductor substrate. | 07-31-2014 |
