20130062247 | BATTERY HOLDER AND DISPENSING PACKAGE - A battery holding and dispensing device can hold a plurality of batteries, in an assortment of battery sizes. The battery holding and dispensing device includes a frame having a plurality of compartments sized and shaped to each receive a battery of a particular battery size and each having a detent for releasably retaining the battery in the compartment. Each compartment has at least one opening in the bottom and lower side to expose a corner of the battery to allow finger ejection of the battery from the compartment past the detent, and to allow the user to touch the batteries to ascertain battery size by feel. The assortment of batteries held in the frame is preferably pre-selected to correspond to the batteries needed by a particular profession. An arrangement for illuminating the frame is provided. | 03-14-2013 |

20150335478 | MEASURING MODULE INCLUDING AN INTERFACE FOR COUPLING TO A LASER DEVICE - An apparatus for laser-assisted eye treatment comprises a laser device and first and second accessory modules. The laser device is configured to provide focused laser radiation and has a coupling port. The first accessory module may form a patient interface and has a contact surface for an eye. The second accessory module includes a measuring device that performs measurements of the laser radiation. In certain embodiments, the measurements include the measurement of a pulse duration of the laser radiation using a detector operating on the basis of two-photon absorption. The first and second accessory modules are configured to detachably couple to the laser device at the coupling port. Only one accessory module can be coupled to the coupling port at a time. Therefore, the first accessory module must be removed from the coupling port before the second accessory module can be attached to the coupling port. | 11-26-2015 |

20100230367 | LIQUID MEDIUM TREATMENT METHOD - The liquid treatment device comprises the nozzle with the throat, the confuser inlet chamber and the diffuser outlet chamber. The vortex cylinder with end-to-end cyclonic ports is coupled to the confuser chamber. The cavitation generator, the shaped head part of which is inserted in the nozzle, is secured axially to the said cylinder with possibility of axial travel. Axisymmetrical internal and external shells and correspondingly are built in the diffuser outlet chamber forming the annular channel in between. During treatment the liquid homogeneous mixture while passing through the cavitation zone is “heterogenized” by both wave slamming, generated with cavitation bubbles collapse, and by bubble generation. Partial “micro-cracking” takes place—bond opening with highly active radical and decreased molecular weight hydrocarbon generation. | 09-16-2010 |
