  • Patent number: 11407537
    Abstract: A product can be packaged by arranging the product on a support, providing a plastic film above the support with the product arranged between the support and the film sheet, and air tightly fixing the film to the support. The process can be implemented using an apparatus that includes a film supply assembly and a base equipment having an upper side defining one or more receiving areas, each being configured for receiving a respective product loaded support; an upper tool is configured for holding a film portion above the product loaded support and then heat sealing the film portion to the product loaded support. Each receiving area has a flat portion and elongated features protruding above the plane of flat portion.

  • Publication number: 20160192248
    Abstract: Methods, apparatuses, and computer program products are disclosed for facilitating a beacon-assisted handover from a macro network to a femto cell during an active call. A femto cell management system assigns a unique identifier to a femto cell, which the femto cell utilizes to broadcast a beacon at a frequency different than the operating frequency of the femto cell. A wireless terminal receives a control message from the macro network directing the wireless terminal to scan particular frequencies. The wireless terminal subsequently provides a report to the macro network identifying attributes ascertained from the scan, which includes attributes associated with the beacon. The macro network then performs a handover from the macro network to the femto cell as a function of the attributes.

  • Patent number: 6129867
    Abstract: The present invention provides a process for producing alveolar cellulosic products (sponges, sponge-cloths, etc.) from a cellulosic raw material, the process comprising:at least partially dissolving a cellulosic raw material in an intrinsic solvent for cellulose;incorporating an effective quantity of at least one pore-forming agent into the resulting mixture, with mixing; said pore-forming agent(s), being compatible with the cellulosic mixture, being capable of generating macro- and micro-pores when it/they is/are actuated;gelling the homogeneous dough thus obtained;treating said gelled dough under conditions in which the cellulose precipitates out and the pore-forming agent(s) present are actuated.The process is an advantageous alternative to the viscose process which is a polluting process. The properties of the products obtained are completely similar to those of products obtained using the viscose process. The (novel) products form part of the invention.

  • Patent number: 6035549
    Abstract: A method for closely protecting materials (10) sensitive to contamination by airborne contaminating agents and placed on a work surface (P). At least one decontaminated gas stream (1, 2) is fed from either side towards the materials in a direction substantially parallel to the work surface, and each gas stream (3) leaves the work surface in an intermediate area between the edges of the work surface and in a direction substantially perpendicular thereto. Alternatively, at least one gas stream is fed towards the materials from above the work surface at an intermediate area between the edges thereof, and in a direction substantially perpendicular thereto, and each gas stream leaves the work surface in a direction substantially parallel thereto and on either side of the materials.

  • Patent number: 5022001
    Abstract: The use of charge pumps to supply bit lines, when programming memory cells connected to a bit line, is avoided by pre-charging this bit line simultaneously with the neutralization of the selection of this bit line. Subsequently, the pre-charging potential is uncoupled and the effects of the neutralization are stopped. It is known that this method of action prevents the breakdown of a single programming potential generator, used to supply all the bit lines. This results in a gain in space in the lay-out of the control circuits of the memory cells in the memory plane. This method can be implemented especially in page mode programming for memories where the memory cells have EEPROM-type floating-gate transistors.

  • Patent number: 4845673
    Abstract: The present invention pertains to a dynamic memory. The voltage of the hot spot of the storage capacitor is carried to a value such that all the cells comprise the same logic value, owing to a potential generator. It is thus possible to write and read bit fields on a large-capacity memory at high speed. This device has applications with respect to image memories and for manufacturing tests.
