Abstract:
The present invention is a spinal fixation device that includes an occipital rod having a first end and a second end, and a spinal rod extending from a connection housing having a first end and a second end. The first end of the spinal rod is integral with a portion of the connection housing and the connection housing is configured with an elongated opening, a rotating plug, and a locking mechanism. The elongated opening is configured for mating with the first end of the occipital plate and the locking mechanism is adapted to enable the occipital rod to be locked in a fixed position.
Abstract:
A fastener, for example a bone screw, is sized to pass through a hole of an implant, for example a bone plate, the fastener having a shaft or anchor portion engageable with body tissue, and a head portion. A locking cap secures to the bone plate and covers the head to block the head and inhibit screw back out. Alternatively or additionally, a locking disc located in the plate hole resiliently deflects downward to allow screw insertion, but is blocked to limit or prevent upward deflection so that screw back out is inhibited.
Abstract:
A bone stabilizing plate includes two plate portions, each affixable to bones of a patient, the plate portions telescoping together with mating rails and grooves. A limiter associated with one of the plate portions sliding engages one a catch associated with the other of the plate portions, when the plate portions are telescoped together, and resists stops telescoping when the plate portions are telescoped a predetermined distance apart. Once the limiter and catch are engaged, the plate portions enable imposition of a minimum compressive force between bones connected to the plates. The limiter is resiliently positioned to deflect into a relief formed in its respective plate portion. A groove positioned proximate the catch enables free telescoping motion limited by the engagement of the catch and limiter, whereby the minimum compressive force between bones is maintained, and Wolfe's Law may apply.

Abstract:
A device for the application of two or more hygienic effects is provided. The device could have one element on a support (e.g. a pick or a toothpick) or multiple elements distributed on a support (a brush, a comb, a toothbrush, a glove or a facemask). In case of multiple elements, a pattern of elements could be created into a topographical surface of elements. Two or more light sources are used for each element whereby each of the light sources is capable of producing a unique light treatment. The two or more light sources could be within the element, i.e., inside or integrated in the element, or could be inside the support and then optically connected to the element.
Abstract:
A method and apparatus are disclosed for laser treatment of surfaces, such as tissue. In a preferred embodiment, the invention employs a unique reflective optical delivery system which produces an improved beam intensity cross-section which reduces thermal injury, increases the precision of the tissue interaction and allows the creation of craters with decreased sizes. Reflective optics provide precise, single-layer vaporization at low power levels without thermal injury to the underlying papillary dermis. Movable optical elements focus and direct the laser beam in a scanning pattern to treat a large area of the surface.
Abstract:
Liquid crystal sunglasses indicating overexposure to UV-radiation comprising a pair of liquid-crystal lenses (12 and 14) a rim (10), a bridge portion (14) which support the lenses, and a pair of temples (18 and 20) which supported by the rim. The rim (10) supports a pair of solar cells (28 and 30) and a dual-photodetector sensor (26) which can separately measure an incident UV-A radiation and a UV-B radiation and convert these radiations into electric signals. The sunglasses's rim also incorporates a microcontroller (36). The lenses have a laminated structure composed of a color mask (43), an input polarizing plate (44), a liquid crystal cell (50) sandwiched between a pair of voltage-controlled active matrices, and an output polarizing plate (46). Each active matrix consists of a plurality of sets of pixels which control the transmission of light through the respective color cells of a mosaic mask. The microcontroller also incorporates a frequency generator (104) and a memory unit. The memory stores an algorithm for calculating thresholds of UV radiation. When these thresholds are exceeded the lenses give to the wearer a warning signal either changing the color of the lenses or causing blinking.
Abstract:
A mirror-based laser processing system, e.g., for laser welding, provided with manual control of movements of a laser welding spot W on an object O being treated. The system includes a laser source (10) which generates a laser beam capable of treating the object (O), a mirror-based micromanipulator (14) which consists of a concave mirror (18) and a convex mirror (16) facing each other, and a laser beam splitter (20) which is located on the path of the laser beam reflected from the concave mirror (18). The laser beam splitter (20) has a coating which reflects the laser beam onto the object (O), but is capable of passing visible and infrared light. Movements of the laser-beam splitter are manually controlled from an external terminal, which is made in the form of a joy stick (50). The joy stick is capable of moving the laser welding spot (W) in any direction over the object's surface in the X-Y coordinate system. Adjustment in the Z-axis direction is performed through a zoom system of the mirror-based micromanipulator (14). The infrared light which is generated by the heated area of the object passes through the laser-beam splitter which transmits visible light to the microscopic head for observation of the object and reflects the infrared light. The latter is processed by a processing unit (38) and is converted into visible thermal information presented on a display (46) in the form convenient for manual control of the position of the welding spot W.
