Patent CA-2124506-A1 (CA)
Inventor: MCDONALD THOMAS M
IPC: H01R13/713
Filed: 1994-05-27
Abstract: An improved ground fault circuit interrupter (GFCI) device requires manual setting following initial connection to an AC power source or termination of a power source interruption. The improved GFCI device utilizes a controlled switching device which is responsive to a load power signal for allowing the relay contact sets of the GFCI device to be closed only when power is being made available at the output or load terminals. The controlled switching device preferably comprises an opto-isolator or other type of switching device which provides isolation between the GFCI input and output terminals when the relay contact sets are open. The improved GFCI device may be incorporated into portable units, such as plug-in or line cord units, for use with unprotected AC receptacles.

Title: Improved phacoemulsification handpiece
Inventor: WHITTINGHAM WILLIAM F
IPC: A61B19/08
Filed: 1993-02-05
Abstract: A surgical device is provided which emulsifies body tissue, irrigates the surgical site with a saline solution, and removes fluids and tissue, via aspiration from the surgical site. More specifically, a surgical handpiece (4) is provided which is particularly suited to be utilized for the removal of cataractous tissue from the eye. In order to prevent cross-contamination of tissue, the surgical device herein incorporates an easily detachable and disposable outer housing (15) to facilitate thorough cleansing of the irrigation solution path and reduce the time and effort required for such cleaning. Moreover, a secure sealing system (42) is provided in the area of the interface between the inner body portion of the handpiece and a stainless steel shell to prevent leakage and contamination of the irrigating solution.
Patent CA-2128984-A1 (CA)
Inventor: WEBER KARON A
IPC: G06F3/0488
Filed: 1994-07-27
Abstract: An interactive method and system are disclosed for supporting and facilitating note-taking tasks in a variety of settings, primarily, though not exclusively, in real time. In one embodiment, the system user uses a stylus device and display to enter notes in the form of handwritten strokes that are stored and correlated with an address, such as a time provided by a system clock. The system user must specify the request of an address from the system, and in this manner, the specification of an address such as time is entirely under the system user's control. Notes are collected in a data structure represented by a spatial region on the display called an address. or time, zone that is created when the user enters a gesture requesting an address from the system. All notes entered in a particular time zone region in the display area are stored in a portion of the data structure correlated with the time associated with that time zone region, and, while time zones are created in sequential time order, notes can be entered in time zones in any sequence. An additional feature is provided for designating a portion of the user's notes as an information designator. A common example of an information designator is a key word, but the information designator function is designed for any task requiring the identification, tracking, and retrieval of specific information contained in the notes. In one embodiment, the method and system avoid recognition of the strokes entered and designated as an information designator by assigning a unique, system-recognizable identifier to each information designator so as to facilitate later access to time values via the unique identifier. An information designator data structure stores both the strokes and the unique identifier of an information designator. A well-designed user interface provides workspaces for creating and using time zones and for easily displaying and using information designators.

Title: Stiff beam suspension system
Inventor: STEPHENS DONALD L
IPC: B60G11/46
Filed: 1995-04-21
Abstract: A suspension system in which a relatively lightweight stiff beam connects the axle to the frame via a connection at one end with a resilient link that allows vertical motion of the end of the stiff beam and transverse motion of the stiff beam to reduce the lateral loads between the axle and the beam and between the beam and the frame rail connection to enable the suspension to be made of fewer and lighter weight components for improved payloads. In the preferred embodiment, the connection between the stiff beam and the frame rail is a C-shape spring allowing the forward connection of a horizontal fore aft link to be moved farther forward to give an increased clearance to the wheel, thereby reducing potential interference between the wheel and the horizontal link and bushing assembly at its forward end.

Abstract: The invention relates to a composition consisting of a dendrimer provided with blocking agents and an active substance occluded in the dendrimer.          According to the invention a blocking agent is a compound which is sterically of sufficient size, which readily enters into a chemical bond with the terminal groups of a dendrimer and which can also be split off from the dendrimer or be modified without thereby affecting the chemical structure of the dendrimer and the active substance. The blocking agent can be provided with protective groups.          Such conjugates have the advantage that the time at which the releasing of the active substance starts, can be controlled.          The invention also relates to a process for the preparation of such a composition and to a process for the controlled release of the active substance.

Title: Electronic article security system
Inventor: WHEELER RICHARD G
IPC: G08B13/24
Filed: 1993-11-22
Abstract: An electronic article security system (10) includes a transmitter (100) for generating electromagnetic energy and a single antenna (150) for emitting electromagnetic energy received from the transmitter (100) to establish an electromagnetic field within the detection zone and for sensing disturbances within the electromagnetic field, including disturbances resulting from a security tag (12) within the detection zone. A receiver (200) processes signals from the antenna (150) relating to sensed disturbances and provides output signals. A data processing and control section (300) analyzes the output signals and determines whether a sensed disturbance  within the electromagnetic field is caused by the presence of a security tag (12) within the detection zone. The output signals from the receiver (200) are analyzed in accordance with predetermined criteria and pattern recognition techniques based upon receiver output signals which would be expected if a security tag (12) were present in the detection zone to establish a security tag probability percentage.

Title: Oxygen respirator
Inventor: IMAI MASAYUKI
IPC: A62B7/04
Filed: 1995-08-23
Abstract: An oxygen respirator with safety and simple handling, comprising a body, a small portable-type oxygen cylinder or oxygen generator mounted on the body, a mask, a first hose transferring oxygen from the body to the mask, a tank member mounted on the body for receiving exhalation, a second hose transferring exhalation from the mask to the body, and a carbon dioxide absorbing material charged in the body for removing carbon dioxide from exhalation sent back from the mask to the body. During emergency and evacuation for example in fire, thus, oxygen is transferred to the mask by removing a trigger or the like. The respirator also enables the reuse of exhalation for respiration.      Despite of the small size, therefore, the respirator can protect a user from risks such as suffocation for a relatively long period of time.

Filed: 1995-10-18
Abstract: An infusion guidewire or catheter for introduction through a selected path in a patient's vascular system to a site in a blood vessel and for infusing a drug or agent into the blood vessel. An elongated tubular body extends between a proximal and a distal end having an infusion device lumen formed therein extending to a plurality of infusion ports formed in a distal infusion segment of the elongated tubular body. The distal infusion segment is pre-biased to assume an infusion configuration when positioned in a blood vessel that tends to present the infusion port toward the blood vessel wall in a low blood flow rate zone and defining a generally centrally disposed perfusion lumen for perfusing blood therethrough. A core wire or a guidewire is inserted through said infusion device lumen from said proximal end into said distal infusion segment for changing the configuration to allow the advancement of the infusion device through the patient's vascular system to a desired site in a blood vessel and for allowing the distal infusion segment to assume said infusion configuration on withdrawal of the corewire or guidewire from the distal infusion segment.
