Linear lighting apparatus and methods

Linear lighting systems and methods. In one example, two or more lighting elements having an essentially linear or curvilinear shape are coupled together to form a lighting system. Each lighting element includes a group of LEDs arranged so as to illuminate the essentially linear or curvilinear shape of the lighting element. Each element may include LEDs to generate the same color light, and / or LEDs to generate light of different colors. Additionally, each element may include one or more controllers to control the LEDs so as to create a variety of temporal and / or color-oriented lighting effects. The controller(s) may employ one or more of a variety of control techniques to control the LEDs, such as those involving analog control signals or pulse-width modulated (PWM) control signals. The lighting elements of the system may each be configured as a “stand alone” unit working within the system, producing respective lighting effects that may or may not be coordinated with each other. Alternatively, two or more elements of the system may be configured as addressable lighting elements to facilitate coordination of the elements as a networked lighting system. Any of the foregoing linear lighting systems may be used in a variety of interior or exterior, as well as direct or indirect, lighting applications. In one example, such lighting systems are particularly well-suited as replacements or substitutes for neon lighting installations.

Vacuum assisted closure pad with adaptation for phototherapy

A modified vacuum assisted wound closure system adapted for concurrent applications of phototherapy having a foam pad for insertion substantially into the wound site and a wound drape for sealing enclosure of the foam pad at the wound site. The foam pad includes an optical pigtail, whereby desired wavelength of light may be directed into and about the wound site. The foam pad is placed in fluid communication with a vacuum source for promotion of fluid drainage. The foam pad is made of a highly reticulated, open-cell polyurethane or polyether foam for good permeability of wound fluids while under suction and is also embedded with an optical pigtail. The optical pigtail comprises an optical fiber that has been formed to fan into a plurality of sections. The fibers of the most distal fanned sections, which are implanted in the foam pad at its base, are provided with tiny optical slots, oriented away from the foam pad and toward the wound site. Each optical slot is made by stripping the cladding from the optical fiber in the desired areas of the fanned sections to form slot radiators. Because it is necessary to trim the foam pad in preparation for therapy, the optical fibers comprise plastics, such as acrylic or styrene. Upon placement of the pad, having the optical pigtail embedded therein, the wound drape is firmly adhered about the VAC therapy suction hose as well as the extending optical fiber to prevent vacuum leakage.

Treatment apparatus with electromagnetic energy delivery device and non-volatile memory

An apparatus for cooling a skin surface includes a support structure coupled to an electromagnetic energy delivery device. The electromagnetic energy delivery device is configured to be coupled to an electromagnetic energy source. A cooling member is coupled to the electromagnetic energy delivery device and is configured to create a reverse thermal gradient through a skin surface. A memory is coupled to the electromagnetic energy delivery device and is positioned at the support structure or the electromagnetic energy delivery device. The memory is configured to store information to facilitate operation of at least one of the cooling member, and the electromagnetic energy source. Resources are coupled to the cooling member to permit different levels of cooling at different times of treatment.
