Abstract: The present invention relates to a light guide for a lamp for dentistry procedures. The light guide provides an optical channel between a light source and a dental substrate. The light guide may be a one-patient use light guide including a recording medium to record the time used. The light guide further provides protection for a patient's soft tissues during treatment.

Abstract: A dental lamp includes a control system adapted to control operation of a light source within the dental lamp. The control system requires that an unexpended light guide including a recordable medium be coupled to a lamp head of the dental lamp, in order to illuminate the light source. The control system records a first data signal on the recordable medium during illumination of the light source indicating that the light guide has been expended. The control system also records a second data signal onto a second recordable medium so that a particular duration of use of the light source may be indicated.

Abstract: A dental lamp boom hinge includes a pivot supporting a dental lamp head and a base supporting the pivot where the pivot may be rotated about a substantially vertical axis with respect to the base. The rotational movement between the pivot and the base is damped with a damping device. The damping device in one embodiment is adjustable to provide a variable level of damping.

Abstract: A direct scheduling system (100,300) that permits automatic appointment scheduling in a computer network environment (304). The system includes a scheduler (108,320) that utilizes scheduling parameters (124,336) to schedule appointments (104) of various types. A user interface (112,324) allows a requester to request that the scheduler schedule an appointment by identifying, among other things, the type of appointment so that a digital appointment identifier (172,332) is created. A mapper (116,328), located between the user interface and scheduler, is configured to map each appointment requested to the corresponding one or more scheduling parameters that the scheduler needs to schedule an appointment of the desired type.

Abstract: A communication system (110) for connecting in real-time an Internet-based network interface (130) to a plurality of backend systems (136), each of the plurality of backend systems having an associated backend communications protocol and requiring an associated backend data format. The system includes a router (112) for receiving a job (124) having a front-end data format and a front-end communications protocol from the Internet-based network interface. The router selects one or more backend systems from the plurality of backend systems as a function of attributes of the job for delivery of the job to the one or more backend systems. The system also includes a plurality of service agents (114, 116, 118), each in communication with an associated one of the plurality of backend systems and configured to translate and reformat the job prior to delivery to the one or more backend systems.

Abstract: The present invention relates to a curing light suitable for curing light curable dental composite materials. The curing light device has a light module housing having at least one heat sink located therein. The heat sink has at least two mounting platforms arranged in different geometric arrangements. More than two light sources may be used, emitting at least two different wavelengths. The curing light includes at least one heat sink having various geometric shapes, which facilitate the arrangement of the light sources in the curing light and minimizing the concentration.

Abstract: This invention relates to a curing light device suitable for curing light curable dental composite material. The device comprises a housing having a substantially hollow interior, a distal end, a proximal end, with the portion of which that is towards the distal end serving also as a handle. A light module is housed in a desirable position in the interior of the housing, and comprises at least one light source, at least one reflector to direct and/or focus the light from the light source, and at least one heat sink located in the proximity of the light source to divert heat away from the light source. The reflector and portions of the housing to which the reflector is attached have the same or substantially the same coefficient of thermal expansion.

Abstract: The present invention relates to a heat sink material that can more efficiently remove or divert heat from a light source or sources with a given weight of heat sink material when compare to a heat sink made of a solid block of thermally conductive material such as metal. It further relates to a heat sink that can more efficiently remove or divert heat from a curing light device when a reduced weight of heat sink material is used. The inventive heat sink has at least one suitable phase change material including organic materials, inorganic materials and combinations thereof. These materials can undergo substantially reversible phase changes, and can typically go through a large, if not an infinite number of cycles without losing their effectiveness.

Abstract: Dentistry equipment includes a voice alert device adapted to annunciate a status of the dentistry equipment or a process performed by the dentistry equipment. The voice alert device in various embodiments employs synthesized and recorded human voices.

Abstract: A processor-based device having a plurality of memory cartridges secured within a chassis by a lever system. The processor-based device comprises an indication system to indicate memory system operating conditions. Each memory cartridge has a protective assembly to protect memory elements within the memory cartridge when the memory cartridge is removed from the processor-based device. The processor-based device is operable such that at least one memory cartridge may be removed from the processor-based device without affecting operation of the processor-based device.

Abstract: The present invention provides for a method for treating an ischemic disorder in a subject which comprises administering to the subject a pharmaceutically acceptable Factor IXa compound in a sufficient amount over a sufficient time period so as to treat the ischemic disorder in the subject. The invention further provides a method for treating an ischemic disorder in a subject which comprises administering to the subject a pharmaceutically acceptable form of inactivated Factor IXa in a sufficient amount over a sufficient period of time to inhibit coagulation so as to treat the ischemic disorder in the subject.

Abstract: A method of adding memory capacity to a computer system. The computer system comprises a redundant memory system including a plurality of memory cartridges. By powering-down a memory cartridge, adding an additional memory module to the memory cartridge, and powering-up the memory cartridge for each memory cartridge in the system, the system can transition from a redundant mode of operation to a non-redundant mode of operation for each power-down, thus allowing the computer system to remain functional during the addition of the memory module. Alternatively, memory cartridges with higher memory capacity than those currently present in the computer system can be used to replace existing memory cartridges in the computer system, using the same techniques.

Abstract: A high-profile air sleep system is disclosed having an air posturizing sleep surface wherein the system comprises a base fabric cover layer, a plurality of resilient blocks overlying the base fabric cover layer, and a middle fabric cover layer overlying resilient blocks. A plurality of air chambers is carried above the middle fabric cover layer, and a resilient pad overlies the air chambers. A top fabric cover layer overlies the resilient pad.
