Abstract:
Disclosed is a system and method for treatment of skin disorders. More particularly, the disclosed invention is directed toward the treatment of acne and acne scarring by treating sebaceous oil glands and the surrounding tissue with an exogenous chromophore composition and then exposing the target tissue to visible, infrared, or ultraviolet light to inhibit the activity of the oil gland and eliminate acne bacteria. The treatment method of the present invention may be futher augmented by enhancing the penetration of the topical composition into the oil gland and surrounding tissue through the use of procedures including enzyme peeling, microderm abrasion, or ultrasound.
Abstract:
A radioactive substance absorber is incorporated into an intravascular radiotherapy source ribbon assembly to prevent the migration of radioactive matter throughout the assembly container. The radioactive substance absorber comprises carbon in various forms and configurations. The radioactive substance absorber is positioned in proximity to the source core and absorbs radioactive materials which break free from the source core, thereby containing the radioactive material.
Abstract:
A system is provided for logging digital messages and forwarding them outside a proprietary telecommunications network. The system includes a service logic program (“SLP”) which determines whether the message is to be forwarded outside the proprietary system. If the message is to be forwarded outside the system, the SLP sends it to the main relay, which logs the message to a log file, and forwards it to a discriminator. The discriminator forwards the message to a sub-relay, which is connected to a vendor application. The sub-relay forwards the message outside the proprietary telecommunications system, to the vendor application.
Abstract:
A detector unit for a detector array includes a photo sensor array, a light guide, and a plurality of scintillator elements formed unitarily with the light guide, the scintillator elements configured to emit absorbed energy in the form of light, the light guide being configured to transmit the light received from at least one of the scintillator elements to a photo sensor, the light guide and the plurality of scintillators being formed from the same material, an area covered by the photo sensors being smaller than an area covered by the scintillator elements and a number of photo sensors being less than a number of scintillator elements. A detector array and a method of manufacturing a detector array are also described herein.

Abstract:
A feed apparatus feed apparatus for delivering particulate material to a foundry furnace having disposed therein a furnace form defining an annulus with the furnace exterior wall for receipt of the particulate material. The novel feed apparatus broadly includes a cover, having a top end, side wall, and a bottom end, the latter of which is adapted to fit on top of the furnace ring or melt deck floor; a rotatable tabletop that is adapted to fit on the top end of the cover while permitting air ingress into the cover and having at least one access port for delivering the particulate material into the interior of the cover; a form top that is adapted to fit within the cover on top of the furnace form to facilitate delivery of said particulate material into the annulus made by the furnace form and the furnace exterior wall; means for rotating the tabletop about the centerline of the cover; and means for centering the tabletop as it rotates about the centerline of the cover. In another aspect of the present invention there is provided a portable dust collector for filtering and removing of dust and particulate materials that are generated in industrial plants, such as coreless electric furnaces. The portable dust collector broadly includes a cover, having a top end, side wall, and a bottom end, the latter of which is adapted to fit on top of the furnace ring or melt deck floor; a rotatable tabletop that is adapted to fit on the top end of the cover while permitting air ingress into the cover and having at least one access port for delivering the particulate material into the interior of the cover; a form top that is adapted to fit within the cover on top of the furnace form to facilitate delivery of said particulate material into the annulus made by the furnace form and the furnace exterior wall; means for rotating the tabletop about the centerline of the cover; means for centering the tabletop as it rotates about the centerline of the cover; and means for filtering the dust and particulate materials that are generated within the cover during plant operations and collecting same for ultimate removal and disposition thereof.
Abstract:
Human and mammalian skin undergoes a variety of changes associated with chronological aging. Various environmental factors, disease states and genetic disorders may accelerate both the appearance of aging skin and also the structural and functional changes associated with aging skin. Ultraviolet radiation from the sun is one of the classic known and well-defined means of accelerating or worsening the aging of the skin and this is frequently termed photoaging. Other environmental factors, such as oxidative stress, free radicals, environmental toxins such as ozone and cultural customs or habits such as tobacco smoking are other known probe accelerators in photo aging skin. A wide variety of other factors known and unknown contribute to accelerated or premature aging of the skin. This invention discusses methods where electromagnetic radiation, in particular, light, can be used to photobiomodulate the activity of living cells to delay, diminish, retard or even reverse the structural and functional effects of aging of the skin and other living cells and tissues. In particular methods described for improving the appearance, structure, function of aging skin, including up and down regulating the genotypic markers for the phenotype of aging skin.
Abstract:
A radioactive source ribbon assembly may be reusably utilized in conjunction with a delivery sheath or catheter for delivering therapeutic dosages of ionizing radiation to various anatomical regions. The radioactive source ribbon assembly comprises an outer jacket formed from or coated with a lubricious coating for insertion into the delivery sheath or catheter. The assembly also comprises a radiation resistant sleeve formed from a braided structure which encapsulates a radioactive source and core. The braided structure is the primary axial load bearing member of the assembly and functions as such without sacrificing assembly flexibility.
Abstract:
A method of fabricating a light guide assembly includes the steps of providing an array of generally frustum-shaped light guides made of a light-transmissive material, providing an optical isolation frame of interconnected slats made of an opaque material, wherein the slats are arranged and profiled to correspondingly match the gaps between the light guides and the outer gap around the periphery of the light guide array, and bonding the light guide array and the optical isolation frame to each other.
Abstract:
A mechanism that provides for communication of heartbeat signals from servers (call agents) to clients (gateways) in a packet telephony network environment. Clients listen for receipt of multicast heartbeats from any of the servers that may be part of a multicast group. A client assigned to a particular server for control messaging, upon failure to receive a response to a message sent to the assigned server and failure to receive a heartbeat from the assigned server, may select a second server from among the servers and re-send the message to the second server. Without receipt of heartbeat signals, the client defaults to a normal retry behavior for re-sending the message first to the assigned server a number of times before attempting to re-send the message to the second server. With receipt of the heartbeat from the second server, the client adopts an aggressive retry behavior by re-sending the message to the assigned server a lesser number of retries before attempting to re-send the message to the second server. The clients use the multicast heartbeats as a hint, allowing them to switch to the more aggressive retry behavior and consequently reduce the time to re-associate with a new server and re-establish a new security association (if IPsec is used), resulting in a drastic reduction in service delay due to server failures.
