摘要:
An optical system and method for providing a visible light beam with a desired characteristic includes a visible light source producing a visible light beam defining an optical train. An optical element is disposed in the optical train to create a modified beam, and that is capable of introducing an undesired characteristic that continuously transitions across at least a portion of the modified beam. A wire-grid polarizer is disposed in the optical train, and has a plurality of elongated elements with at least a portion that continuously transitions to a different characteristic. The wire-grid polarizer is positioned and oriented in the optical train with the different characteristic corresponding to the undesired characteristic of the modified beam to obtain a visible light beam with a desired characteristic substantially across the visible light beam.

A system for controlling slack in a winch rope associated with a vehicle can include a winch, a plow, and a support member pivotably coupled to the plow and carrying a pulley that receives the rope for raising and lowering the plow. A limit switch can be operatively associated with the winch and configured to selectively enable and disable lowering of the plow by the winch. A first member can be carried by the support member and operatively associated with the switch. A biasing member can bias the support member to a first position when a load on the winch rope is below a predetermined threshold. The first member can be in at least substantial alignment with the switch when in the first position. The switch can change an activation state upon the first member being in the first position to automatically disable lowering of the plow by the winch.

摘要:
A heating assembly, including a blanket portion and a control apparatus for electrically heating the blanket portion. The control apparatus generates direct current power of desired wave form to enable the assembly to be used for warming patients without interference of medical equipment as may be used in the process of a surgery. Alternate power sources include battery power and alternating current power transformed by a transformer into direct current power.
摘要:
A method and system for wrinkle reduction. The method includes the steps of positioning and applying a patch to skin of a consumer and adhesively securing the patch to the skin. A chemical composition on the patch includes both active ingredients and adhesive. A pair of electrodes are connected to a battery-driven, microprocessor-based controller. A current is applied through the electrodes in the patch for a selected time. The chemical composition in the patch is propelled into the consumer through use of the current in order to relax the skin of the consumer. The patch is removed and any residue of the chemical composition is massaged into the skin.
