Abstract: A pulse-echo ranging system is described employing a microwave transducer head (100) providing an echo profile output signal which is largely compatible with receivers (204) and echo processing systems (206) designed for acoustic transducers. The transducer head employs novel microwave pulse generators (20a, 20b) each utilizing a microwave cavity (20a, 20b) excited by an avalanche discharge through a small signal diode (D2a, D2b) initiated by avalanche of a driver transistor (TR1a, TR1b) by a trigger pulse. Repeated pulses from one generator (2a) are transmitted by an antenna (12) towards a target, and return are mixed with pulses from the second generator (26) which are subject to a progressively swept delay relative to the transmitter pulses. The mixer output is applied to a tuned amplifier (110) to extract components at an alias frequency related to the sweep rate of the delay relative to the transmitter frequency. The aliased signal is passed to a receiver (204) and echo processing system (206).

Title: Roller bushing assembly
Inventor: ZIERDEN DEAN
IPC: B60G11/12
Filed: 1998-02-23
Abstract: A roller bushing assembly (21d, 21e, 21f) designed to enable a low tolerance, frictional fit within an out-of-round or otherwise distorted support member (5, 9) includes a bushing member (29a, 216) having an outer surface (102) machined to provide various axially spaced, annular grooves (127-130, 132 and 242-250). Between or directly adjacent respective ones of the annular grooves (127-130, 132 and 242-250) are defined a plurality of axially spaced and radially extending ribs (113-122 and 232-240). The axial outermost ribs (113, 122 and 240) are preferably elongated relative to the remaining ribs (114-121 and 232-239) and have annularly chamfered portions (124, 125 and 252). The ribs (113-122 and 232-240) are adapted to shear upon mounting of the bushing member (29a, 216) within an out-of-round or otherwise distorted support. By providing the shearable ribs (113-122 and 232-240), the bushing assembly (21d, 21e, 21f) can be effectively mounted within a greater range of varying sized support members. In accordance with a first embodiment, the bushing member constitutes a sleeve (29a) within which is mounted at least one bearing unit (33, 34). The shearing of the ribs (113-122) assures that the bearing unit (33, 34) will not be excessively pre-loaded in a radial direction. In accordance with a second embodiment, the bushing member constitutes a pin (216) formed with terminal stub shafts (222 and 223) which are mounted within respective bearing units (186) positioned within pockets (182, 183) formed in a pair of shackle links (164, 165).
Patent CA-2285419-A1 (CA)
Inventor: CHEN JAMES C
IPC: A61K45/00
Filed: 1998-04-15
Abstract: A plurality of light sources that emit light having a long wavelength are energized for an extended period of time to increase the likelihood of two photon absorption by cells that have preferentially absorbed a photoreactive agent such as psoralen. The cells are preferably microscopic metastatic cancer cells that are diffusely distributed throughout a treatment site, for example, within an organ. The plurality of light sources are arranged in a spaced-apart array, mounted on a support plate that includes a plurality of conductive traces. A plurality of such arrays are preferably mounted to a flexible sheet that can conform to an outer surface of an organ being treated. Because the light emitted by the light sources is in the infrared or near infrared waveband, it penetrates deeply into the tissue at the treatment site. The duration of the treatment and the number of light sources employed for administering the therapy increases the likelihood of two photon absorption by the metastatic cancer cells, which has been shown to activate the photoreactive agent to destroy cancer cells in a tumor, even though the characteristic light absorption waveband of the photoreactive agent is in the ultraviolet waveband.

Title: Recording material
Inventor: MORIYA KAZUYOSHI
IPC: B41M5/52
Filed: 1999-11-12
Abstract: The present invention provides a recording material in which a resin layer containing both of a large particle size sponge silica having a particle size 8 to 18µm and a small particle size sponge silica having a particle size 1 to 7µm is provided as a record reception layer on at least one face of a base material. The sponge silica means silica of a sponge-like structure having many pores in silica particles. It is preferable that a pore volume of silica used for the present invention is 0.7 to 7ml/g, and 0.8 to 4ml/g is particularly preferable. If the pore volume of sponge silica is too small, there is a tendency that the record reception property of the reception layer is lowered.

Title: Reversible geling co-polymer and method of making
Inventor: GUTOWSKA ANNA
IPC: A61K47/32
Filed: 1998-05-28
Abstract: The present invention is a thermally reversible gel or geling copolymer that is a linear random copolymer of a [meth-]acrylamide derivative and a hydrophilic comonomer, wherein the linear random copolymer is in the form of a plurality of linear chains having a plurality of molecular weights greater than or equal to a minimum geling molecular weight cutoff. Addition of a biodegradable backbone and/or a therapeutic agent imparts further utility. The method of the present invention for making a thermally reversible geling copolymer has the steps of: (a) mixing a [meth-]acrylamide derivative with a hydrophilic comonomer in a solvent with an initiator forming a reaction mixture; (b) copolymerizing the reaction mixture and forming a first linear random copolymer having a plurality of linear chains having a plurality of molecular weights; and (c) purifying the synthesized first random copolymer and obtaining a second linear random copolymer having a plurality of molecular weights greater than or equal to a minimum geling molecular weight cutoff. The gel is enhanced by either combining it with a biodegradable backbone and/or a therapeutic agent in a geling solution made by mixing the copolymer with an aqueuos solvent.  Advantages of the present invention include (1) the thermally reversible gel of the present invention exhibits a thermodynamic stability, and when geled, will not reverse to the liquid state upon dilution but may reverse to the liquid state only in response to a temperature change and (2) the gelation occurs without substantial syneresis. Moreover, the thermally reversible gel of the present invention has lower initial viscosity more suitable for tissue perfusion.

Title: Apparatus and processes for laser deformation of dielectric particles
Inventor: KAS JOSEF A
IPC: G02B21/32
Filed: 1999-03-04
Abstract: Apparatus and processes for laser deformation of dielectric particles are disclosed. In one implementation, a determination is made as to whether a particle is trapped between two or more sources of laser light. Deformation of a particle under the laser light is also determined, and the laser sources may be adjusted to vary the power of the laser light to both trap a particle and stretch the particle.  Deformation of a particle may be controlled by exposing the particle to two or more counterpropagating laser beams at an intensity and under conditions effective to deform the particle, and measuring its deformation. An optical micromanipulation tool, also referred to as an optical stretcher, may thus use a tunable laser to trap and deform cells between two counterpropagating beams generated by the laser. One possible application of embodiments of the present invention is to detect the deformation of cancer cells.

Title: Off-line broadband network interface
Inventor: OJARD ERIC
IPC: H04L29/06
Filed: 1999-02-26
Abstract: A network interface is presented that receives packet data from a shared medium and accomplishes the signal processing required to convert the data packet to host computer formatted data separately from receiving the data packet. The network interface receives the data packet, converts the analog signal to a digitized signal, and stores the resulting sample packet in a storage queue. An off-line processor, which may be the host computer itself, performs the signal processing required to interpret the sample packet. In transmission, the off-line process converts host-formatted data to a digitized version of a transmission data packet and stores that in a transmission queue.  A transmitter converts the transmission data packet format and transmits the data to the shared medium.
