Devices, systems and methods are disclosed for the ablation of tissue. Embodiments include an ablation catheter that has an array of ablation elements attached to a deployable carrier assembly. The carrier assembly can be constrained within the lumen of a catheter, and deployed to take on an expanded condition. The carrier assembly includes multiple electrodes that are configured to ablate tissue at low power. Additional embodiments include a system that includes an interface unit for delivering one or more forms of energy to the ablation catheter.

Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material.

An oxygen-based biomass solid fuel combustion system and method has an air separator for separating oxygen from air providing a supply of oxygen for feeding oxygen to a solid fuel combustion chamber. An airlock feeds a metered amount of solid fuel to the solid fuel combustion chamber. A burner stage having a firetube for collecting fuel gases from the solid fuel combustion chamber combusts the collected fuel gases with further oxygen from the separator and heats a boiler to generate steam. A heat utilization device (e.g. an electrical generator) may be connected to the steam boiler. Nitrogen-free diluent gases (e.g. argon and carbon dioxide) are used to control combustion process temperatures. The usable heat energy and useful byproducts are extracted from the different stages of the process.

This invention provides a vehicle control apparatus constructed so that during the control of a downshift for deceleration, braking shocks can be reduced and the amount of energy regenerated can be increased, and a hybrid vehicle equipped with the control apparatus.The hybrid vehicle 1 includes wheels 14, an engine 12, a motor 11, a multi-stage transmission 20 that reduces motor torque and transmits the reduced torque to the wheels, and a brake 15 that brakes the wheels. During deceleration downshift control, a hybrid control module 100 provides distribution control of the regenerative torque of the motor 11 and the braking torque of the brake 15 so that the total braking force of the vehicle during gear shifting matches a target value.

A device for subdividing vehicle cabs and / or storage spaces into a number of sub-portions, comprising a number of deformable walls and a drive unit for moving the walls between an open position, in which the walls do not subdivide the cab and / or the storage space, and a closure position, in which the walls subdivide the cab and / or the storage space into the sub-portions. The walls become deformed during movement between the closure position and the open position. Also included is a method for subdividing vehicle cabs and / or storage spaces into a number of sub-portions and a vehicle.

Lighting fixtures, systems, and methods of using the lighting fixtures that can achieve radically increased energy efficiency and visual effectiveness, are disclosed. The invention also offers the potential for decorative effects, supplementary background lighting, and other lighting effects. Various embodiments use light sources capable of individual focus, replacement, and control of operation. Fixtures allow mounting of the light emitting components to achieve a large effective aperture / diameter of the fixture in relation to the distance from the illuminated area, producing improved illumination. The light emitting components may be installed on parts of the fixture that may be oriented individually, thereby allowing infinite and / or incremental adjustment of the overall light emission pattern to achieve desirable illumination effects. Desirable lighting effects are further achievable by selection of the lighting type (LED, incandescent, fluorescent, etc), combinations thereof, and by selection of the fixture aperture / diameter, axis, and intensity. Shielding of the light sources to avoid glare to bystanders may be included.

Systems, methods, and devices used to treat eyelids, meibomian glands, ducts, and surrounding tissue are described herein. In some embodiments, an eye treatment device is disclosed, which includes a scleral shield positionable proximate an inner surface of an eyelid, the scleral shield being made of, or coated with, an energy-absorbing material activated by a light energy, and an energy transducer positionable outside of the eyelid, the energy transducer configured to provide light energy at one or more wavelengths, including a first wavelength selected to heat the energy-absorbing material. Wherein, when the eyelid is positioned between the energy transducer and the scleral shield, the light energy from the energy transducer and the heated energy-absorbing material of the scleral shield conductively heats a target tissue region sufficiently to melt meibum within meibomian glands located within or adjacent to the target tissue region.

An in-vehicle power transmission apparatus is equipped with a plurality of power split rotors and a power transmission control mechanism. The power split rotors work to split power among a rotary electric machine such as a motor-generator, an internal combustion engine, and a driven wheel of the vehicle. If rotational energy, as outputted from the power split rotors, is defined as being positive in sign, the power split rotors are so assembled that when the power transmission control mechanism establishes transmission of the rotational energy that is positive in sign as the power from a first rotor that is one of the power split rotors to the internal combustion engine, the other power split rotors are so linked as to provide output rotational energies which are opposite in sign to each other. This enables the speed of the first rotor to be placed at substantially zero.

The present invention relates to a method and apparatus for treating of marine growth on the surface, such as the holes of boats and ships.A confinement arrangement is used to confine a volume of heated fluid against the surface. The confinement arrangement is retained against the surface by maintenance and mounts rollers so that it can be moved over the surface to treat other parts of the surface. A heated fluid is provided to the confined volume from an external heater.

An apparatus for cooling a computer system includes a primary cooling loop. The primary cooling loop includes an evaporator configured to cool at least a component of the computer system, an ambient cooled condenser connected to the evaporator, a first pump to provide a coolant flow within the cooling loop, a pressure regulator configured to maintain a selected pressure in the primary cooling loop, and a controller responsive to changes in outdoor ambient conditions and an amount of heat dissipated by the computer system and configured to dynamically adjust the pump and pressure regulator in response thereto.
