Title: Breast biopsy system and method
Inventor: BURBANK FRED H
IPC: A61B10/00
Filed: 1999-03-02
Granted: 2008-01-15
Abstract: An apparatus and method are provided for precisely isolating a target lesion in a patient's body tissue, resulting in a high likelihood of "clean" margins about the lesion when it is removed for diagnosis and/or therapy. This approach advantageously will often result in the ability to both diagnose and treat a malignant lesion with only a single percutaneous procedure, with no follow-up percutaneous or surgical procedure required, while minimizing the risk of migration of possible cancerous cells from the lesion to surrounding tissue or the bloodstream. In particular, the apparatus comprises a biopsy instrument having a distal end adapted for entry into the patient's body, a longitudinal shaft, and a cutting element disposed along the shaft. The cutting element is actuatable between a radially retracted position and a radially extended position. Advantageously, the instrument is rotatable about its axis in the radially extended position to isolate a desired tissue specimen from surrounding tissue by defining a peripheral margin about the tissue specimen. Once the tissue specimen is isolated, it may be segmented by further manipulation of the cutting element, after which the tissue segments are preferably individually removed from the patient's body through a cannula or the like. Alternatively, the specimen may be encapsulated and removed as an intact piece.
Patent CA-2341841-C (CA)

Granted: 2007-02-27
Abstract: A dough divider including a hopper with a lid and a press plate vertically slidable within the hopper. The hopper is adapted to accept dough between the lid and the press plate, and the press plate is adapted to move towards the lid in order to compress the dough between the press plate and the lid within the hopper. The dough divider further includes a two part pressure relief system including a reversible cylinder assembly and at least one pressure relief opening. The reversible cylinder assembly is connected to the press plate and adapted to move downward in order to allow the press plate to move towards a bottom of the hopper when pressure applied to a top of the press plate from the dough within the hopper reaches a predetermined level. The pressure relief opening is adapted to relieve pressure within the hopper between the press plate and the lid by allowing the dough to escape from the hopper through the pressure relief opening when the press plate has reached the bottom of the hopper.

Title: A work table having tool counterbalancing means
Inventor: BARCLAY DWAINE
IPC: B23Q1/62
Filed: 2001-04-25
Granted: 2009-01-06
Abstract: The present invention provides a work table for use with a tool, comprising an inclined work surface, which is substantially planar and is supported by a frame having a base; a gantry movably attached to the work surface and having two ends, a longitudinal axis and extending within a plane parallel to the work surface; a movable tool mount slidably attached to the gantry for removable attachment of the tool wherein the tool mount and the tool have a combined effective weight; a first movement means attached to one end of said gantry for translation of the gantry over said work surface; a second movement means attached to the tool mount for translation of said tool between the ends of the gantry; and a weight counterbalancing means operatively associated with the tool mount for neutralising the combined effective weight. Neutralisation of the weight is accomplished by attaching the tool mount to a counterbalancing system that counterbalances the combined effective weight of the tool and tool mount along the length of the gantry, enabling its smooth movements when the work surface is in an inclined position.

Patent CA-2374891-C (CA)
Inventor: SASAKI HIDESHI
IPC: A01D34/90
Filed: 2002-03-06
Granted: 2004-11-30
Abstract: In a plant cutter apparatus, a handling rod includes an outer pipe portion, an inner pipe portion and three radial stay portions interconnecting the outer and inner pipe portions. The three stay portions are arranged, about an axial centerline of the rod, at non-equal angular intervals in such a manner that angles formed between the three stay portions differ from each other. Thus, the rod has a cross-sectional configuration asymmetric about the axial centerline. Geometric moment of inertia of the thus-constructed handling rod takes different values in all angular positions about the axial centerline, and thus the inherent vibrating frequency of the rod also takes different values in all the angular positions. Consequently, the rod's inherent vibrating frequency coincides with a frequency of vibrations transmitted from a drive source unit in only one of the angular positions, so that resonant vibrations of the handling rod can be avoided easily.

Title: Fluorescent intensity method for assaying binding between proteins or peptides
Inventor: ERIKSON GLEN H
IPC: G01N21/64
Filed: 2000-06-20
Granted: 2007-08-28
Abstract: A method for assaying specific binding between a fluorophore-labeled probe a nd an unlabeled target is provided. The method includes detecting a quenching effect on fluorescence emitted by the fluorophore-labeled probe resulting from binding. The method is conducted without separating complexes of the target and probe from the free target and free probe prior to quenching effect detecting, and without providing a signal quenching agent to quench fluorescent light. Preferably, the probe and target are amino acid-containing compounds, such as proteins. The method can be used fo r a variety of applications, including screening for drug candidates having optimum binding properties, and quantifying and classifying the binding characteristics between peptide- containing compounds. The method is more sensitive than conventional assays, enabling the analysis of minute samples and low affinity binding interactions between receptors and ligands that are below t he detection limits of conventional technology.

Granted: 2007-08-07
Abstract: A magnetic hook, jaw-type clip or spring clip has a rectangular housing containing magnets. A conventional hook or clip is attached to the housing. A finger tab extends from one edge or wall of the housing. When a user desires to remove the magnetic hook from a mounting surface he or she places a finger tip on a curved portion of the finger tab causing the upper edge of the magnetic hook to move away from the mounting surface. This results in a pivoting action forcing the magnetic hook away from the mounting surface with little or no sliding. A flexible fin may be placed adjacent the magnets and extend slightly beyond the housing. When the magnet is placed against a metal surface the flexible fin will bend to a smaller height and bear against the metal surface thereby improving the load carrying capacity of the device.

Title: Photon windowing kernel
Inventor: BURGENER ROBIN A
IPC: G06F9/44
Filed: 1994-10-14
Granted: 2003-12-30
Abstract: The most commonly available operating systems over the last two decades have had a monolithic kernel architecture. These operating systems often employ windowing systems or graphical user interfaces (GUI's) by adding complex functionality to the monolithic kernel itself. Microkernel operating systems offer a superior architecture, but heretofore, where not available with an effective GUI. While monolithic operating systems support complex instructions such as "drawing"or managing an input device, microkernel architectures seek to operate with a minimal set of primitives, delegating the more complex tasks to external processes. The invention provides an effective GUI for managing the interaction of multiple displays, by defining a multi-dimensional "event space" in which the displays. Each software program operating on the system has a set of characteristics, which define its location in the event space. This paradigm allows a microkernel operating system to manage the software programs by managing this small set of characteristics.
