摘要:
A culture flask comprising a culture chamber in a flask body comprising an even bottom wall with a growth surface on the top side, an even cover wall at a section from the bottom wall, and side walls that bridge the distance between the margins of the bottom wall and cover wall, an opening that is in adjacent regions of a side wall and the even cover wall at a distance from the bottom wall, and a hollow cylindrical flask neck that is connected to the margin of the opening and is aligned at a sharp angle to the growth surface so that the serological pipette, a scraper, a cannula or another elongated device for adding or removing material can be placed on the rear corners of the growth surface from the outside through the flask neck.

A pulsed light communication device has a plurality of indicator light emitting diodes emitting diodes emitting at least one of a plurality of wavelengths of colored light to correspond to a designated color assigned to a security level for a network. A continuous uninterrupted modulated pulsed light emitting diode light signal may be generated having a sensitivity threshold detection level exceeding minimal parameters of a photodetector.

An LED light and communication system includes at least one optical transceiver, the optical transceiver including a light support and a processor. The light support has a plurality of light emitting diodes and at least one photodetector attached thereto. The processor is in communication with the light emitting diodes and the at least one photodetector, where the processor is constructed and arranged to illuminate at least one of the light emitting diodes to generate a light signal which in turn includes at least one embedded data packet. The at least one embedded data packet communicates global positioning system (GPS) location information.

An osteosynthesis system for treating fractures of tubular bones includes an intramedullary nail with an elongated nail body consisting of a hard metal material with two end sections and a middle section therebetween that has at least one transverse screw hole close to the end for screwing in at least one bone screw into each end section. The nail body is solid or has a through-channel arranged in the center in the cross-section of the nail body. In the middle section at least two transverse one-sided screw holes are placed proximate to a fracture. Screw holes are formed as inlays made out of soft metal material securely joined to the nail body, and bone screws with an initial thread consisting of hard metal material that can be screwed into the bone and screw holes while forming threads.
摘要:
A method and device for measuring the position of sections with an absorbing substance in multi-segment filter rods of the tobacco processing industry by measuring a varying shift of the resonance frequency A and/or spread of the resonance line B during movement of the rod in the longitudinal direction, using a microwave resonator, which has a field concentration in a spatial area, wherein this spatial area is smaller in the rod direction than the segment length to be determined, forming a difference quotient ΔA of the resonant frequency shift A and/or ΔB of the resonance line spread B relative to the longitudinal direction, determining local extreme values of the respective difference quotients, and assigning local extreme values as a position of a transition from a section with higher content of absorbing substance to a section without, or with lower content, of absorbing substance, and vice versa.

A method of handling parcels (2) and a logistics center (1) for handling parcels, use is made of superposable racks (5) and motor-driven shuttle carts (6) that are remotely controlled by a central processing unit (7) to travel in freely guided manner and that are suitable for docking with each rack (5), each parcel (2) is unloaded onto a rack (5) and the destination of the parcel is identified (103), a specific location is assigned (104) to said rack (5) using an outward shipping plan, and said corresponding shuttle cart (6) is caused to move (105) so as to store said parcels (2) side-by-side and in superposed manner, and then, using an inward delivery plan, each rack (5) is docked (110), and each parcel (2) is transferred (111) from said stowage zone (11) to a loading point (3) so that parcels (2) are presented in their order of delivery.
摘要:
An LED light and communication system includes one or more optical transceivers that have a light support having a plurality of light emitting diodes and one or more photodetectors attached thereto, and a processor in communication with the light emitting diodes and the one or more photodetectors. The processor is constructed and arranged to generate a communication signal. The one or more optical transceivers are engaged to a lighting fixture within a building. The one or more optical transceivers are constructed and arranged to communicate with a name tag.
