Abstract: The present invention discloses a method of manufacturing a diaper that has multiple moisture sensing elements on interior side of its bottom impermeable layer or on any surface of the top permeable layer. The moisture sending elements are made by spraying conductive ink on a moving sheet of either the bottom impermeable layer or the top permeable layer, before other layers of the diaper are attached. Spraying of conductive ink on the moving sheet causes parallel lines of conductive inks to be formed on the layer. The parallel lines of conductive ink run through the entire length of either of the layers and are designed to get connected with a detecting device. When a user urinates inside the diaper, the moisture causes a closed circuit between at least two of the parallel lines of conductive inks. These formations of closed circuits, between parallel lines of conductive inks, are detected by the detecting device.

Abstract: A remote incontinence detection/monitoring system is provided with its methods of operation and manufacturing. The system comprises a diaper embedded with markers that are each associated with a dedicated frequency. Each marker is operable to relay or reflect towards an external receiver, or absorb or interfere with the wireless signal tuned to its dedicated frequency that is emitted from an external transmitter. When in contact with liquid, a marker loses its ability to relay, reflect, absorb, or interfere with the wireless signal tuned to its dedicated frequency, indicating the diaper is saturated on the marker's spot. A method of manufacturing diapers embedding components for said system is provided wherein each diaper manufactured from a same roll of materials will be embedded with the same number of markers reacting to the same serial of pre-set dedicated frequencies with not a single frequency missing or repeating within each and every diaper.

Abstract: The present invention discloses a method of manufacturing a diaper that has multiple moisture sensing elements on interior side of its bottom impermeable layer or on any surface of the top permeable layer. The moisture sending elements are made by spraying conductive ink on a moving sheet of either the bottom impermeable layer or the top permeable layer, before other layers of the diaper are attached. Spraying of conductive ink on the moving sheet causes parallel lines of conductive inks to be formed on the layer. The parallel lines of conductive ink run through the entire length of either of the layers and are designed to get connected with a detecting device. When a user urinates inside the diaper, the moisture causes a closed circuit between at least two of the parallel lines of conductive inks. These formations of closed circuits, between parallel lines of conductive inks, are detected by the detecting device.

Abstract: The invention discloses a system for accessing and viewing Internet content on a portable device by means of a proxy server. The server requests web content, renders it and sends compressed image parts to the device. In order for the device to be cost-competitive, its processing operations are generally limited to decompressing image parts and displaying them. The server sends information to the device that allows it to locally create, display and manage text boxes, in which the user can type immediately. As a user types into a local text box, text input data is communicated to the server and processed therein before further requests for web content. By simultaneously managing multiple text boxes locally, the present invention reduces instances of data transfer from the server to the device, which decreases the likelihood of lag and improves the performance of the device.

Abstract: The present invention discloses a solar module, preferably for use within a solar energy concentrator system. The solar module comprises multiple solar cells that are divided into sets. The solar cells constituting a set form a parallel circuit, while the sets are connected together in series. The sets are arranged such that they each generate substantially the same amount of current despite solar cells potentially receiving an uneven diffusion of solar radiation. The voltage of each set can thus be added together without yielding any significant efficiency loss. In a further embodiment, electrical contacts and conductors with relatively high resistance on the solar cells are located on their back sides, coupled to conductors with relatively low resistance on a PC board substrate incorporated as a substrate to the solar module. This circuit reduces the overall resistance of the circuit, especially when integrated to a solar energy concentrator system.

Abstract: A system for sensing wetness in an ordinary diaper comprises a disposable sensor unit that can be adhered to an absorbent layer of a diaper, and comprises a sensor strip and a support structure. The sensor strip has electrical circuit with conductive elements as wetness sensors printed on the bottom surface of the strip, wherein a closed electrical circuit is formed when an amount of body fluid is present that subsequently triggers an alerting device. The support structure has multiple slots cut out on it to expose conductive elements to body fluids and also keeps the conductive elements at a specific height from the absorbent layer of the diaper such that no alert is generated because of the body fluid content retained by a top permeable layer of the diaper after absorbing the body fluid. The thickness of the support structure is maintained such that the height created between the conductive elements and the top permeable layer of the diaper, does not cause capillary action.
