Patent CA-2279643-A1 (CA)
Inventor: JONES DANE
IPC: A47C17/175
Filed: 1999-08-04
Abstract: A futon frame is convertible between a bed position and a sitting position and includes a back portion and a seat portion. The back portion is oriented generally upright when the frame is in the sitting position and is oriented horizontally when the frame is in the bed position. The seat portion is hingedly attached to the back portion to permit relative movement of the back portion with respect to the seat portion. A connector releasably connects the back portion and seat portion to cause the back portion to move on movement of the seat portion in a first direction about a pivot point. A support supports the back portion with respect to a supporting surface and the back portion includes a pair of opposed outer edges. A pair of first pins are provided, each connected to one of the outer edges of the back portion and the support and a pair of first slots, each in the other of the outer edges of the back portion and the support are provided for constraining movement of the first pins within respective first slots. Each first slot includes a contact surface preventing upward movement of the pins with respect to the first slots when the frame is in the bed position and curved such that the pins are releasable from the contact surface upon movement of the back portion in a pivoted direction, when the frame is moved from its bed position to its sitting position.

Title: Launching tool for objects downhole
Inventor: SMITH SIDNEY K JR
IPC: E21B33/16
Filed: 1999-11-02
Abstract: The invention comprises a tool for launching objects downhole, such as one or more plugs in a desired sequence. The movements leading to the release of the individual plugs are regulated by virtue of displacement of oil through at least one orifice. The wiper plugs are retained in the tool until such time as they are physically displaced beyond the lower end of the tool. The biased retainers holding the plugs within the tools are released upon a predetermined movement of the plugs beyond the lower end of the tool. If the retaining mechanism for the plug does not automatically release upon sufficient extension of the wiper plug from the tool, a pressure assist can be used to launch any given plug. The darts used to move an actuating piston to release the plugs are separated from the plugs and retained in the tool so that they do not need to be drilled out later.

Title: Cluster ablation electrode system
Inventor: COSMAN ERIC R
IPC: A61B18/14
Filed: 1998-07-24
Abstract: A multiplicity of high frequency electrodes in a cluster configuration may be inserted into tissue of a patient's body for producing heat ablation of abnormal tissue such as a tumor. The electrodes are connected coherently to the voltage output of a high frequency generator. An enlarged ablation volume is accomplished by the electrode cluster with reduced risk of hemorrhage because of the smaller diameter of the individual electrodes of the cluster. The electrodes terminate in conductive tips, which are cooled by a fluid coolant to further facilitate enlarged ablation volumes. Very large ablation volumes are accomplished by this process and apparatus. Various cluster electrode configurations may be adapted to meet specific clinical requirements.

Filed: 1998-07-27
Abstract: The present invention is directed to an isolated protein or polypeptide which elicits a hypersensitive response in plants as well as an isolated DNA  molecule which encodes the hypersensitive response eliciting protein or polypeptide. This isolated protein or polypeptide and the isolated DNA  molecule can be used to impart disease resistance to plants, to enhance plant growth, and/or to control insects on plants. This can be achieved by applying the hypersensitive response elicitor protein or polypeptide in a non-infectious form to plants or plant seeds under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds. Alternatively, transgenic plants or plant seeds transformed with a DNA molecule encoding a hypersensitive response elicitor protein or polypeptide can be provided and the transgenic plants or plants resulting from the transgenic plant seeds are grown under conditions effective to impart disease resistance, to enhance plant growth, and/or to control insects on plants or plants grown from the plant seeds.

Title: Enhanced fatigue strength orthopaedic implant with porous coating and method of making same
Inventor: SHETTY H RAVINDRANATH
IPC: C23C24/08
Filed: 2000-03-03
Abstract: A method for producing an orthopaedic implant having enhanced fatigue strength. A forged implant substrate having an elongated stem is incorporated with a melting point lowering substance. Then, metal particles are sintered to the substrate, forming a porous layer on the substrate which enhances bone ingrowth or the mechanical interlock with bone cement. Advantageously, the sintering occurs at a lower temperature than if the substance were not incorporated into the substrate, which in turn results in an enhanced fatigue strength of the inventive implant. The fatigue strength of a forged or cast implant can also be improved by nitrogen diffusion hardening and/or thermally processing the implant after the porous coating is adhered by sintering. Further, the fatigue strength can be further improved by combining incorporating the melting point lowering substance with nitrogen diffusion hardening and/or aging treatment subsequent to sintering.

The radio unit, for example, a radio telephone, includes a first processor, a reader for reading a credit amount and a personal access number from a debit card, and a transceiver for communicating, using radio waves, a credit signal. The base station receives and relays the credit signal over a communications channel to the end station. The end station includes a switch to generate a first control signal to allocate the credit amount of the debit card to the radio unit, and to set a radio unit access number of the radio unit to the personal access number of the debit card with a communications path through the base station. The end station also generates a second control signal for changing the credit amount and the personal access number of the debit card. The base station may be connected to a debit meter. The radio unit sand the debit meter respond to the second control signal to change the credit amount and the personal access number using magnetic writers or writer processors to store an updated credit amount and personal access number on a magnetic strip on a debit card or on a chip on the debit card as the debit card is used in the radio unit. The personal access number may be used as a telephone number of the radio unit.

Abstract: Devices and methods for creating a series of percutaneous myocardial revascularization (PMR) channels in the heart. One method includes forming a pattern of channels in the myocardium leading from healthy tissue to hibernating tissue. Suitable channel patterns include lines and arrays. One method includes anchoring a radiopaque marker (38) to a position in the ventricle wall, then using fluoroscopy repeatedly to guide positioning of a cutting tip (32) in the formation of multiple channels. Another method uses radiopaque material injected into each channel formed, as a marker (38). Yet another method utilizes an anchorable, rotatable cutting probe (30) for channel formation about an anchor. Still another method utilizes a multiple wire radio frequency burning probe, for formation of multiple channels simultaneously. Still another method utilizes liquid nitrogen to cause localized tissue death.

Inventor: NAIM GHASSAN
IPC: H04L12/56
Filed: 2000-05-16
Abstract: A method of selecting which one of a number of wireless station is to be allocated a particular transmit opportunity is provided, for example the opportunity to transmit an air interface unit such as a MAC frame. For each wireless station, a transaction length is maintained indicating how many transmit opportunities are required to transmit an upper layer packet to or from the wireless station, and a delay parameter is also maintained for each wireless station indicative of how long since the wireless station was last selected. A group of wireless stations to compete for the right to transmit or receive during the particular transmit opportunity is selected, and for each of the group of the wireless stations, a transmit priority is computed which is a function of transaction length and the delay parameter. Finally, the wireless station in the group of wireless stations with the highest transmit priority is selected as the wireless station to transmit or receive an air interface unit during the particular transmit opportunity.      Preferably, the transmit priority is also a function of a wireless station priority for each wireless station.
