Abstract: A system for controlling prepaid delivery of utilities includes a utility meter with a cutoff device for enabling or disabling delivery of a utility; and a server connected to the utility meter via a network. The utility meter receives a usage limit from the server, measures usage of the utility by the load, and when the usage limit is exceeded, activates the cutoff device. The utility meter transmits the measured usage to the server at configurable intervals. The server maintains an account balance associated with the load, receives the measured usage from the utility meter, and decrements the account balance based on the measured usage. When the account balance is exhausted, the server sends a command to activate the cutoff device to the utility meter. Otherwise, the server generates a further usage limit based on the account balance, and sends the further usage limit to the utility meter.

Abstract: For tracking a plurality of objects in a three-dimensional space two-dimensional pictures objects are recorded with two black and white cameras out of two different imaging directions. Both first pictures and second pictures of the two cameras are simultaneously exposed at two points in time in equal ways, a point in time at which the second pictures are exposed for a first time following to a point in time at which the first pictures are exposed for a last time at a much shorter interval than the two points in time of exposure of both the first and second pictures. First and second distributions of real positions of the individual objects are determined from their images in the first and second pictures, respectively; and temporally resolved trajectories of the individual objects in the three-dimensional space are determined from the first and second distributions of real positions.

Abstract: A candle assembly for making a personalized scented candle including a candle body comprises a coring device that is configured to remove a core from the candle body, the coring device including (i) a leading edge that selectively extends into the candle body; and (ii) a plurality of measurement markers that measure a depth of the leading edge within the candle body. The coring device can be configured to remove the core from the candle body to form a cavity in the candle body. Additionally, the measurement markers can be utilized to determine a depth of the cavity formed in the candle body by the coring device.

Abstract: The invention relates to a process and an apparatus for the preparation of a crosslinkable rubber mixture for vehicle tires, lines, drive belts and other industrial rubber articles, which can be carried out at least semicontinuously. The present invention is based on the discovery that the experiments known from the prior art to carry out the batchwise process usually used at least partly continuously have failed in particular because of the problem that the crosslinking agents have to be mixed rapidly and homogeneously with the base mixture, also referred to as rubber base mixture, without the mixture consisting of the base mixture and the crosslinking agents heating up too strongly. According to the invention, attention was therefore focussed on reliably mixing the base mixture homogeneously with the crosslinking agents and minimizing the mixing time. A first measure for achieving the desired aim consists in first mixing the crosslinking agents with one another before they are mixed with the base mixture.

Abstract: For reducing a circulation of wake vortexes in a wake turbulence behind an airplane flying over ground at low altitude, at least one ring vortex of airflow is generated at the ground on each side of a vertical middle plane of the airplane. Each ring vortex has a vortex axis and a direction of propagation, wherein the vortex axis is oriented at an angle with regard to the ground, and wherein the propagation direction is oriented upwards from the ground; and each ring vortex disturbs at least one wake vortex to induce its decay.

Abstract: An ultrasonic gas flowmeter includes a measuring pipe with flowing gas, transmitting and receiving sound transducers, transmission and reception electronics, and evaluation electronics. The sound transducers (7, 8, 9, 10) are designed as capacitive electro-acoustic ultrasonic transducers to construct a flowmeter with improved capacity, especially in view of temperature stability and the reduction and consideration of a temperature profile. Devices (5, 6) are provided to level the gas temperature profile and to minimize the influence of the temperature profile on the flow measurement. A more accurate and dependable detection of the volume flow or the mass flow of gases is to be achieved, especially in highly dynamic flows, for the method of determining the flow of gases whereby the mean flow velocity is determined and the flowing gas quantity is determined with highly synchronized resolution from the two transit times of two acoustic signals.

Abstract: A method for the utilization of a woven or loop-formingly knitted fabric which acquires an electrostatic charge as a result of a specific treatment for filtering airborne, dusty allergens such as pollen in a pollen guard mountable in front of windows and doors over the whole area thereof.
