Abstract: A system and method for rendering flows and volumes includes the steps of generating a preintegrated table, the preintegrated table having a plurality of entries, each of the plurality of entries having color information and opacity information, generating illustrative effects based on the plurality of entries of the preintegrated table and displaying the illustrative effects.

Abstract: A dental apparatus and process for the transmission of dental data by means of a transmitter and a receiver in a wireless manner.

Abstract: A fluid distribution module (1) for causing and monitoring the circulation of fluids from and to a patient through an extracorporeal blood treatment device, comprises a degassing device (11) connected to a connecting structure (10). The degassing device (11) comprises a first chamber (12) having a lower inlet (13) for a liquid and a second chamber (14) having an upper opening (79) closed by a hydrophobic membrane (78) and an outlet (15) for discharging the liquid. The connecting structure (10) has at least a first and a second conduits (20, 21) defined therein, wherein the first conduit (20) comprises a first end for connection to a discharge tube (7) from the treatment device and a second end connected to the inlet (13) of the first chamber (12) of the degassing device (11), and the second conduit (21) comprises a first end connected to the outlet (15) of the second chamber (14) of the degassing device (11) and a second end for connection to a blood return tube (6) to a patient.

Abstract: An adjustable rear pistol sight has a sight base and a sight block. The sight block is secured in a recess in the sight base and has both windage and elevation adjustment capabilities. The sight base has a dovetail that will be receivable in a cooperatively shaped notch in a slide of a pistol with which the adjustable rear sight is intended for use. The sight has no sharp edges or surfaces and is essentially snag-free.

Abstract: A device for removing material from a workpiece, in particular for removing a hard substance, such as tooth enamel or dentine from a tooth, or for removing ceramic materials, has a laser for irradiating the workpiece in a locally limited ablation area where material is removed, and a handling part (1) which receives the laser or is connected thereto by an optical fiber element or by a mirror arrangement. The handling part (1) is used to position the laser beam (3) in the ablation area and has a distance measurement device (11 to 15, D1, D2) to monitor the depth of material removal. While the material is being removed, the distance measurement device (11 to 15, D1, D2) measures the distance to the workpiece surface in the ablation area and therefore the depth of material removal by means of the material-removing laser or of a measurement beam (11) generated by another laser.

Abstract: A method and apparatus for the ablation of hard biological material, such hard dental material, using a rapidly pulsed laser employ a crystal or absorber film disposed in the propagation path of the laser radiation, the crystal or absorber film being disposed at the laser output and serving as an interface with an optical conductor which conveys the laser radiation to the treatment site. The crystal or absorber film smooths the time/intensity characteristics of the pulsed laser radiation to the extent that transmission to the treatment site using optical wave guides is possible. Additional protective features are provided to prevent the ablated biological material to destroy the exposed optical end surfaces of the treatment applicator. Additional design features improve the ergonomic efficiency of the handpiece and its ability to be sterilized.
