Illumination provided to the interior of a convex surface can be controlled using a plurality of internal barriers separating light sources such as light emitting diodes. Such controlled illumination can simulate phases of the moon using logic which can be limited to yes or no Boolean decisions, thereby minimizing the complexity of required input.

摘要:
A method of determining at least one parameter of a waveguide (3) from wavefield data acquired from wave propagation in the waveguide including obtaining first and second dispersion curves (9a, 9b, 9c) in the frequency domain from the wavefield data. A frequency interval between the first dispersion curve and the second dispersion curve is found, and this is used in the determination of at least one parameter of the waveguide. The frequency separation Δƒ(V) between the first and second dispersion curves may be found at a particular value of the phase velocity V, and the thickness h of the waveguide can be found using: Δ f ( V ) = c 1 2 h 1 - c 1 2 V 2 Here, c1 is the velocity of wave propagation in the waveguide. This may be found from the asymptotic velocity values of the dispersion curves.

A computer system has at least one data defect memory, at least one address defect memory and also a test program. The computer system is connected to a memory module that has a memory space with defect-free and defective memory cells, a plurality of data lines, and a plurality of address lines. The addresses of the defective memory cells in the memory space and the data lines that are connected to the defective memory cells are determined from the information items of the address defect memory and also from the information items of the data defect memory.

An ink application device for tattooing or for making permanent make-up includes a handle, a needle drive, a needle, a needle nozzle and a protective cap. The device further includes at least two modules releasably connected to one another. One of the modules is formed as a reusable base module with an integrated needle drive, and the other module is a sterilized disposable module in which all components of the manual device capable of being infected by bodily fluids of a customer are integrated. The device can be constructively divided into two or three separate modules: a basic module, a disposable or hygienic module and an optional ink module. The basic module corresponds to the handle that includes the needle drive and is designed such that the hygienic module can be safely attached and connected to the integrated needle drive.
摘要:
Two methods check functional capability of electrical connections between address lines of a printed circuit board of a memory module and address line contacts of an integrated semiconductor memory chip mounted on the printed circuit board. Ruptured solder contacts are conventionally examined optically or investigated by electrical resistance measurements; however, the latter do not work in the case of memory modules with a number of semiconductor chips, the pin contacts of which are connected in parallel by the address lines. The methods make it possible to locate interrupted contacts on individual address lines by the indirect use of a write-read access to the semiconductor memory chip, specifically utilizing the misrouting of writing and reading commands produced by defective contact connections.
