University of Vigo posted this:New wheel slip reset controller for brake systemsThe main motivation for using reset control is the overcoming of fundamental limitations or trade-offs of conventional controllers: with the conventional controllers if we want a fast braking response, the system is fragile and sensitive to uncertainties; and if we want a robust system, this requires slower braking actions. Reset control is a novel technique that achieves more robust and fester braking responses in a way that no other conventional controller is able to produce.

However, all of them have serious disadvantatges. 1) with software that uses atom-atom potentials: Advantages: fast and capable of working with large molecules. Disadvantages: the "blind tests" carried out by the "Cambridge Crystallographic Data Centre" are giving a 50% maximum success in the predictions. 2) with software based on DFT calculations: Advantages: good results Disadvantages: they are computationally very slow, so they are only used for very simple molecules compared with drug molecules. In addition, they have errors predicting van der Waals interactions and weak hydrogen bridges if not corrected empirically. 3) with software using ad hoc potentials for each molecule obtained from systematic exploration of the surface potential of intermolecular interactions: Advantages: efficient and faster. Disadvantages: some potentials should be calculated for each molecule studied, which are complex and slow, and is not general. The approach presented here is new and unique because the potential Pixel has never been used before for drawing polymorphic predictions and it has shown to present the advantages of all the alternatives combined. This is the first research group which has brought the potential Pixel to this level of calculation. The potential calculations and the applicability of the methode based on pixels have the same quality that the sophisticated ab initio based potential calculations. Besides, this is much faster than DFT (Functional-Based Theory)-based and ad hoc potentials ..

RAMOT at Tel Aviv University Ltd. posted this:Effective cooling of ICs with microchannel heatsinkA miniature heat sink containing microchannels for extremely effective forced air cooling of high power electronic devices. Multiple vortex rings are generated and propagate along the channels. This causes optimum mixing of the air which leads to enhanced heat removal from the hot device. Due to the small size of the microchannel, a large number of such channels can be placed over a given heat generating surface in a single layer or multiple layers (the thickness of a layer is less than 1mm) to yield a very high heat removal rate within a very small size heat sink. The channels can also be integrated as separate layers in a 3-D electronic circuit architectures, located between layers of heat generating components to effectively remove heat and resolve hot-spot regions.

RAMOT at Tel Aviv University Ltd. posted this:autonomous pressure relieving aids for wheelchair patientsThe present invention provide a seat cushion for an individual suffering from loss of sensation in the buttocks but having sensation in higher regions of the trunk. The cushion may be used, for example, in individuals who have undergone spinal cord injury (SCI). The cushion of the invention provides tactile stimulation to regions of the surface of the individual’s body where the individual has retained tactile sensitivity (e.g. above the SCI level) to induce the individual to shift his sitting position. The cushion thus provides tactile sensory compensation, by transferring the sense of weight-bearing pressures from an insensitive body site which bears bodyweight loads (e.g. a body site affected by a neural injury) to a different, sensitive site which is not necessarily weight-bearing at the time. By repetitively shifting the location of the tactile stimulation, the cushion promotes frequent changes in posture, which tend to reduce the risk of pressure ulcers. Project ID : 8-2011-265
RAMOT at Tel Aviv University Ltd. posted this:Flexible Blade RheometerThe innovation is a low-cost flexible extension to the standard off-the-shelf rotational blade rheometer. State of the art rotational rheometers use fixed and rigid blades, which rotate against a fluid and have limited accuracy at extremely high or low viscosities. Our inventions replaces the rigid blades with flexible blades work by utilizing fluid mechanics and fluid-blade interaction principles and allow to detect small changes of viscosity. The very small viscosity changes are amplified through the interaction of the thin boundary layers on the sidewalls, the high shear in the small gap between the wall and the blade and on the rotating flexible blade itself.
