| 20100129523 | IOL INSERTION APPARATUS AND METHODS FOR MAKING AND USING SAME - Apparatus, and methods of making and using apparatus, for inserting intraocular lenses (IOLs) are disclosed. The apparatus includes a hollow tube having an interior wall defining a hollow space through which an intraocular lens may be passed from the open space into an eye. A lubricity enhancing component is covalently bonded to the hollow tube at the interior wall in an amount effective to facilitate the passage of the intraocular lens through the hollow space. The lubricity enhancing component includes a substituent component effective to reduce hydrolysis of said lubricity enhancing component relative to an identical lubricity enhancing component without the substituent component. | 05-27-2010 |

| 20090088839 | POLYMER COMPOSITIONS SUITABLE FOR INTRAOCULAR LENSES AND RELATED METHODS - A polymeric material with a molecular response time that makes it suitable for use near fragile body tissues. The polymeric material is useful for both low modulus and high modulus applications thereby simplifying the multi-part polymeric article manufacturing process and creating better integrated multi-part polymeric articles. Cross-linked polymers with different moduli may be obtained utilizing the same or similar starting materials but modifying the amount of catalyst, the amount of cross-linking agent, and/or the amount of methyl vinyl cyclics. | 04-02-2009 |
| 20090163602 | SILICONE CONTAINING POLYMERIC MATERIALS - A polymeric material with a variable modulus of elasticity is described herein. The polymeric material described herein is useful for forming implantable medical devices (e.g. ophthalmic lenses, breast implants, and body augmentation devices). In addition, medical devices formed from the polymer material can be used to controllably release a therapeutic agent. Also, the polymeric material may be used to prepare topical compositions or other applications or devices where control of a mechanical property such as material modulus is important. | 06-25-2009 |

| 20090203183 | Method for integrating SIGE NPN and Vertical PNP Devices - According to one exemplary embodiment, a method for forming an NPN and a vertical PNP device on a substrate comprises forming an insulating layer over an NPN region and a PNP region of the substrate. The method further comprises forming a buffer layer on the insulating layer and forming an opening in the buffer layer and the insulating layer in the NPN region, where the opening exposes the substrate. The method further comprises forming a semiconductor layer on the buffer layer and in the opening in the NPN region, where the semiconductor layer has a first portion situated in the opening and a second portion situated on the buffer layer in the PNP region. The first portion of the semiconductor layer forms a single crystal base of the NPN device and the second portion of the semiconductor layer forms a polycrystalline emitter of the vertical PNP device. | 08-13-2009 |

| 20100234782 | CIRCUMFERENTIAL WALKER - An orthopedic device in the form of a circumferential walker includes a first member (posterior shell) and a second member (dorsal shell) corresponding to the first member. An outsole or plantar shell portion is attached to, or formed on or with the posterior shell. A hinge mechanism is provided between the posterior and dorsal shells to allow the dorsal shell to be swung away from the posterior shell in order to accommodate an anatomical limb therein. Inflatable bladders having perspiration wicking channels and/or openings are provided within a liner for insertion between the posterior and dorsal shells. Quick-connecting buckle and retaining assemblies can be provided to allow a user to quickly don and doff the orthopedic device. | 09-16-2010 |
| 20110146032 | STRAPPING SYSTEM - A strapping system includes a flexible, textile strap having locking elements. The strap defines an attachment portion upon which a reinforcement element formed from a solid mass of polymeric material inseparably and integrally secures. The locking elements of the strap are embedded at least in part into the thickness of a reinforcement element. | 06-23-2011 |

| 20090072368 | PACKAGE FOR MONOLITHIC COMPOUND SEMICONDUCTOR (CSC) DEVICES FOR DC TO DC CONVERTERS - A multichip module defining a dc to dc converter employs a monolithic chip containing at least two III-nitride switches (a monolithic CSC chip) mounted on a conductive lead frame. The CSC chip is copacked with an IC driver for the switches and with the necessary passives. The module defines a buck converter; a boost converter, a buck boost converter, a forward converter and a flyback converter. The drain, source and gate pads of the monolithic CSC chip are connected to a lead frame by solder or epoxy or by bumping attach and a conductive connector or wire bonds connect the switch terminal to lead frame. | 03-19-2009 |
