The present invention provides method and apparatus for treating tissue in a region at depth by applying optical radiation thereto of a wavelength able to reach the depth of the region and of a selected relatively low power for a duration sufficient for the radiation to effect the desired treatment while concurrently cooling tissue above the selected region to protect such tissue. Treatment may be enhanced by applying mechanical, acoustic or electrical stimulation to the region.

A method of treating an object with radiation that includes generating volumetric image data of an area of interest of an object and emitting a therapeutic radiation beam towards the area of interest of the object in accordance with a reference plan. The method further includes evaluating the volumetric image data and at least one parameter of the therapeutic radiation beam to provide a real-time, on-line or off-line evaluation and on-line or off-line modification of the reference plan.

Devices and methods for treating tissue with radiation, including light and other optical radiation, in a manner that is eye-safe are described. In one embodiment, a photocosmetic treatment device has a cavity into which tissue to be treated is drawn. The device determines whether the tissue is safe to treat and whether the tissue may be tissue associated with the eyes, such as an eyelid. In another embodiment, an eye-safe pulse of radiation is provided at a time interval prior to treatment of the tissue. The pulse is at a wavelength of radiation that the human eye perceives as particularly intense and uncomfortable, even though the pulse is not dangerous or destructive. If the device is oriented to treat eye tissue, directly or through the eyelid, the pulse will cause an aversive reaction in the subject being treated that inhibits the treatment.

There is described a fluid treatment system that is particularly well suited for treating ballast water on a shipping vessel. The present fluid treatment system is characterized by having two general modes of operation. A so-called ballasting mode and a so-called deballasting mode. In the ballasting mode, water is pumped from the sea or other body of water in which the shipping vessel is located to a ballast fluid inlet in the present fluid treatment system. Thereafter, it passes through the filter separation and radiation treatment sections in the fluid treatment zone of the fluid treatment system. Next, the fluid exits the fluid outlet of the fluid treatment system and it is pumped to one or more ballast tanks that are located on the shipping vessel. In the deballasting mode, water contained in the ballast tank(s) is pumped to a deballasting fluid inlet of the fluid treatment system after which it is treated in the radiation section only—i.e., in the deballasting mode, water substantially bypasses the fluid separation section of the fluid treatment system. Next, the treated fluid exits the fluid outlet of the fluid treatment system and is discharged overboard the shipping vessel. A valve system is used to switch between ballasting mode and deballasting mode.

The invention provides a two-stage phase shift-driven power factor corrector which comprises a power unit and a control unit which matches the power unit. The power unit as a whole is two-stage staggered structural power sub-circuits. Each stage of power subcircuit contains two power devices connected in parallel, and inputs single-phase AC sinusoidal voltage, outputs direct voltage for power supply and generates an input voltage signal, an output DC voltage signal and a boost inductive current signal. The control unit inputs a direct voltage reference signal and the above three routes of signals from the power circuits. By a power-factor correction algorithm, four routes of phase shift-driven pulse signals which respectively have 1/4 switching period for phase shift are generated to be used for correspondingly driving the four power devices in the power unit, controlling on-off of the four power devices and realizing power-factor correction. According to the invention, the circuit structure is simple, thus being conducive to miniaturization design of an inductor. Meanwhile, switching loss and conduction loss of the power devices are reduced, thus being conducive to type selecting and heat radiation processing of the power devices.
