Publication number: 20160345988Abstract: An instrument can comprise an instrument body, a cross-pin, and a ring. The instrument body can be configured to be partially inserted into an intramedullary canal of a bone having a bone resection. The cross-pin can extend through the instrument body, and the ring can be movably coupled to the cross-pin and positionable on the bone resection. The ring can be configured to pivot about a longitudinal axis of the cross-pin such that an angle of the ring relative to the instrument body approximates a surface angle of the bone resection relative to the instrument body. Additional apparatus, methods, and systems are disclosed.Type: ApplicationFiled: May 19, 2016Publication date: December 1, 2016Inventor: Andrew Hopkins

Publication number: 20160259851Abstract: Systems, apparatuses, and methods for generating a parser training set and ultimately a correct treebank for a corpus of text, based on using an existing parser that was trained on a different corpus. Also disclosed are systems, apparatuses, and methods for improving the operation of a parser in the case of using a less familiar set of training data than is typically used to train conventional parsers. This can be used to generate a more effective and accurate parser for a new corpus (and hence more accurate parse trees) with significantly less effort than would be required if it was necessary to generate a standard size training set.Type: ApplicationFiled: March 3, 2016Publication date: September 8, 2016Inventors: Mark Andrew Hopkins, Mark Edwin Schaake, Samuel Stuart Skjonsberg

Publication number: 20150289985Abstract: The present disclosure relates to a shoulder prosthesis comprising a glenoidal component having a glenoidal articulation surface and a humeral component having a humeral articulation surface, and a separate mobile glenohumeral bearing component comprising a glenoidal bearing surface and a humeral bearing surface arranged on opposite sides of the glenohumeral bearing component. The glenoidal bearing surface contacts in an implanted state the glenoidal articulation surface and/or the humeral bearing surface contacts in an implanted state the humeral articulation surface. At least one of the glenoidal and humeral bearing surfaces is concave. The glenohumeral bearing component is disposed in an implanted state between the glenoidal component and the humeral component. Both the glenoidal and humeral articulation surfaces are convex.Type: ApplicationFiled: December 19, 2013Publication date: October 15, 2015Inventor: Andrew Hopkins

Patent number: 9109118Abstract: A cellulosic inclusion-thermoplastic composition that includes cellulosic inclusions and a thermoplastic polyolefin that forms a matrix in which the cellulosic inclusions are dispersed. A maleated polymer and a polar thermoplastic polymer resin of a polyamide or polyester are provided to improve adhesion between the cellulosic inclusions and the thermoplastic polyolefin. The polar thermoplastic polymer resin is characterized by a melting temperature greater than that of the thermoplastic polyolefin. The composition as provided has increased break tensile strength relative to a composition devoid of the polar thermoplastic polymer resin but otherwise is unchanged. The break tensile is measured at 23° Celsius and at an elongation rate of 50 millimeters per minute.Type: GrantFiled: September 26, 2013Date of Patent: August 18, 2015Assignee: RHETECH, INC.Inventors: Robert C.

Publication number: 20150150687Abstract: The disclosure includes methods and systems for making orthopedic connections where there is unique adjustability to the connection. Illustratively, one embodiment provides a connecting assembly for connecting a plurality of orthopedic components. Such connecting assemblies can include a first orthopedic component that provides a female bore. Additionally the assembly can include a second orthopedic component that can be or include a male-type connecting member that is positionable in the bore of the first orthopedic component. In one preferred form, the male-type connecting member will be a quasi-spherical member. The quasi-spherical member can include a textured outer surface, e.g., for contacting one or more walls or surfaces in the bore in a fashion that removeably locks or helps to removeably lock or fix the quasi-spherical member in the bore.Type: ApplicationFiled: December 2, 2014Publication date: June 4, 2015Inventor: Andrew Hopkins

Patent number: 8401184Abstract: An integrated circuit assembly having monitoring circuitry for observing the internal signals of the system so that its properties are captured. The system properties are manipulated so that they can be used as a pseudo random number and or as the basis number for an encryption key. The monitoring circuitry having: manipulation circuitry to transform monitored data and combine it with previously manipulated values; and registers to store previously manipulated values; and counters to count events; and condition detection circuitry for detecting when a signal is at a specific value or range of values. Optionally the monitoring circuitry which has the functionality for capturing system properties may be combined with other monitoring circuitry, which has the functionality required by a debug support circuit. The monitoring circuitry avoids replication of resources by sharing parts of specific monitoring circuits like counters.Type: GrantFiled: August 2, 2007Date of Patent: March 19, 2013Assignee: University of Essex Enterprises LimitedInventors: Andrew Hopkins, Klaus McDonald-Maier, Gareth Howells
