Title: In mold closing mechanism and method
Inventor: GOMES MANUEL
IPC: B29C45/57
Filed: 2005-04-21
Abstract: The present invention is a mechanism for folding plastic injection molded parts after the parts have been molded and while the parts are still on the mold core half.  The mechanism consists of a mold core half having one or more mold cores. The mold core half has a finger movably mounted adjacent the mold core half and movable along a predetermined path between a first position wherein the finger is clear of the mold core and a second position wherein the finger bears against the part on the mold core so as to fold the part. The invention also includes a drive (either electrical, hydraulic or pneumatic) for driving the finger between its first and second positions. The present invention also consists of a method of in-mold folding of a foldable plastic part. The method consists of projecting a finger across a face of the mold core half and towards the plastic part sitting on the mold core such that the finger engages a lower edge of a first portion of the plastic part. The finger is then forced upwardly away from the mold core and towards a second portion of the plastic part in order to fold the first portion onto the second portion. After folding the plastic part, the finger is moved clear of the mold core so that the part can be fully ejected from the mold core and so that the injection mold can proceed with the next molding cycle.

Abstract: A schema model allows objects to be contextualized by using stored values th at are used to localize the object. The values used for localizing each object that is to be localized are stored in a container class element that is associated with the object that is to be localized. The object having localized term values stored in a container class element is related to another object wherein the objects are related using one of a hierarchical term and an entry term relationship. The associate values allow a user to override by redefinition default values presented by a controlled vocabulary system. The user can further relate term objects by using hierarchical-, ent ry- , and related-term relationships. This arrangement allows users and systems to more effectively re-use standard data definitions.

Abstract: A digital counter (e.g., Fig. 1) that uses non-volatile memories (12, 14, 16 , 18, ~) as storage cells, wherein the storage cells are sub-divided into two groups, one for the implementation of a rotary counter (20, 22) that keeps track of the less significant part of the count and a binary counter (10) th at keeps track of the more significant part of the count. The rotary counter implements a counting method that maximizes the count that can be obtained before the endurance limit of the memory is reached by making sure that each change of state of each cell is recorded as one count and that all cells in the rotary counter experience two change of state in every cycle. The binary counter (10) records the number of cycles the rotary counter has gone throug h.

Title: Monitoring thermal conditions to vary operation of an ultrasonic needle tip of a surgical instrument
Inventor: MACKOOL RICHARD J
IPC: A61B19/00
Filed: 2004-04-15
Abstract: A method and apparatus to operate a surgical instrument in response to a thermal condition being detected that warrants curtailment of further operation. When the thermal condition is reached, command signals are generated that cause a needle of the surgical instrument to either have its vibrational speed slowed, have its vibrational movement stopped, or have it withdrawn from its relative position. The detection is of infrared radiation wavelengths and is carried out with either a thermal imaging device of a thermal recognition device. A corresponding temperature of the detected infrared radiation wavelengths is compared to a critical temperature to determine whether the thermal condition has been reached.
