  • Publication number: 20200306523
    Abstract: Described herein are microelectrode array devices, and methods of fabrication, assembly and use of the same, to provide highly localized neural recording and/or neural stimulation to a neurological target. The device includes multiple microelectrode elements arranged protruding shafts. The protruding shafts are enclosed within an elongated probe shaft, and can be expanded from their enclosure. The microelectrode elements, and elongated probe shafts, are dimensioned in order to target small volumes of neurons located within the nervous system, such as in the deep brain region. Beneficially, the probe can be used to quickly identify the location of a neurological target, and remain implanted for long-term monitoring and/or stimulation.

  • Publication number: 20190351219
    Abstract: Described herein are microelectrode array devices, and methods of fabrication and use of the same, to provide highly localized and efficient electrical stimulation of a neurological target. The device includes multiple microelectrode elements arranged along an elongated probe shaft. The microelectrode elements are dimensioned and shaped so as to target individual neurons, groups of neurons, and neural tissue as may be located in an animal nervous system, such as deep within a human brain. Beneficially, the neurological probe can be used to facilitate location of the neurological target and remain implanted for long-term monitoring and/or stimulation.

  • Publication number: 20190275352
    Abstract: There is described herein methods and systems for generating a treatment plan for delivery of a radiation dose to a subject based on a plurality of radiation modalities, each radiation modality having a delivery element and an associated weight associated thereto. The treatment plan is constructed iteratively by considering the different radiation modalities and different delivery elements and selecting those that meet one or more goals regarding a target dose distribution.

  • Publication number: 20190134400
    Abstract: A preferred frequency is identified, being usable to stimulate a neurological target within a mammalian body using at least one microelectrode positioned at or near the target. To establish efficient and effective stimulation, an impedance analyzer is provided for measuring electrical impedance values indicative of a microelectrode-tissue interface across a range of different frequencies. A preferred one of the measured electrical impedance values is identified as being closest to a pure resistance. The neurological target can then be stimulated at or near the frequency associated with the preferred impedance value (peak resistance frequency), thereby promoting desirable traits, such as optimum charge transfer, minimum signal distortion, increased stimulation efficiency, and prevention of microelectrode corrosion. The peak resistance frequency can be used to determine an preferred pulse shape.

  • Publication number: 20170175368
    Abstract: An improved, wholly mechanical, valve unit is provided to automatically allow for flow between a high temperature liquid line and a cooler temperature liquid line in order to maintain the immediate availability of hot liquid immediately upstream of the valve, especially for hot water used in a building. The valve unit of the present invention includes a thermally-activated, bi-metal, or more broadly bi-flexive, valve disc, and a smaller diameter valve seat that concentrically contacts the valve disc intermediate the outer circumference and the center of the disc. The bi-flexive disc is provided two-sided, circumferential support, thus substantially equalizing the pressure against both sides of the disc, even when in the closed valve position between the higher temperature, higher pressure, hot water line and the lower pressure cold water line. The valve opens when the temperature differential across the valve disc decreases below a preset amount.

  • Patent number: 4783608
    Abstract: An electric motor provided with a bearing of improved design has a stator (1) supported by a mounting frame (3) and a rotor (4) in rigidly fixed relation to a shaft (5), the shaft being rotatably mounted in a plain bearing (7) placed within a tubular support (8) which is rigidly fixed to the motor frame (3). A sleeve (23) composed of material having a sufficient degree of elastic deformability to absorb vibrations is interposed between the outer face (24) of the bearing (7) and the inner face of the tubular support (8). The electric motor is intended in particular to equip propeller-type fans and is primarily applicable to direct-current motors of the electronic commutation type.

  • Patent number: 4481436
    Abstract: The electric motor with radial air gap comprises a rotor, a stator having a magnetic circuit and windings which form winding heads projecting with respect to the magnetic circuit at the axial ends thereof, a case whose end wall extends radially and a sensor for detecting the position of the rotor fixed on an electrically insulating disc separating that end wall from the winding heads situated on the same side as this wall, applied and immobilized against the case. The sensor has terminals connected to connecting wires which issue from the case at a point remote from the connection point thereof with the terminals, and the internal face of the disc has guide means for leading the wires from one point to the other while passing at a distance from the rotor and the winding heads, which come very close to the end wall.
