The invention provides an anti-fouling lighting system (1) configured for preventing or reducing biofouling on a fouling element (1201) of an object (1200). The fouling element (1201) is during use at least partly moving and at least temporarily exposed to water. Fouling is prevented by irradiating an anti-fouling light (211) onto said fouling element (1201). The anti-fouling lighting (1) system comprises at least one laser light source (2) configured to generate the anti-fouling light (211) and to provide said anti-fouling light (211) to said fouling element (1201) during use, wherein the system (1) is arranged such that during use the fouling element (1201) at least partly moves with respect to the laser light source (2).

A patient warming system for stabilizing and/or heating and cooling a patient includes a plurality of solid-surface sections arranged for attachment to a surgical table and a warming pad layer comprising a plurality of warming pads configured for removable connection to the plurality of solid-surface sections. At least one of the plurality of solid-surface sections includes a power connector for connection to an external power source. Each warming pad of the plurality of warming pads includes a foam insulation layer, a distributed heating element layer having a warming-pad power connection for connection to the power connector, an isothermal layer, and a flexible waterproof layer. Power supplied to the warming-pad power connection of the distributed heating element layer of the respective warming pad can be used to provide a user-selected uniform temperature over the surface of the flexible waterproof layer in order to prevent hot spots.

Typical prior art circuits for ignition and operation of UV lamps do not optimize power usage through the whole cycle of ignition and ongoing operation. Typically, the higher power required to initially ignite the UV lamp is not diminished once the UV lamp is burning brightly and at a desired temperature. The circuit of the present invention utilizes a sensor to monitor the light emitted from the UV lamp and a sensor to measure the temperature of the device containing the UV lamp as voltage is applied to it. Once the constant light and desired temperature are achieved, the voltage boost converter is latched away and constant lower voltage is provided to the UV lamp from that point forward, thus optimizing the energy consumption or the energy used for a battery powered device incorporating a UV lamp.

Proposed are a method and a system for removing L-FC in a plasma etching process, in which L-FC, which is condensed on a wafer, an electrode, a substrate, a head, or the like, is removed by using infrared or ultraviolet rays in a plasma etching process using an L-FC precursor.

A method for manufacturing a structure on a surface of a workpiece (1) is disclosed, the method having the following steps: applying a liquid base layer (2) onto the surface of the workpiece (1); spraying on at least one droplet (3) into the not yet congealed base layer (2), wherein the at least one droplet (3) at least partially, preferably completely, penetrates into the base layer (2); fixing the base layer (2); and at least partially removing the at least one droplet (3). Further, a second method having the following steps is disclosed: spraying on at least one droplet (3) onto the surface of the workpiece (1); applying a liquid base layer (2) onto the surface of the workpiece (1), wherein the base layer (2) flows around the at least one droplet (3) and preferably at least partially covers the at least one droplet (3); fixing the base layer (2); at least partially removing the at least one droplet (3). Finally, a device for performing the methods is disclosed.
