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: 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.

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: The invention discloses a method for accessing and viewing Internet content on a portable device by means of a proxy server, which method reduces the amount of data transferred to the device and improves its performance. Based on the content of each part of a web page, the server calculates, assigns and saves unique identifiers for each of them. If the web page is revisited or refreshed, unique identifiers are calculated and assigned for parts of this revisited or refreshed page. Parts that have the same identifier as a part previously saved are not transferred as the part with the same identifier in a memory of the device is instead used for display. Various processes can be combined with this method to reduce the number of instances by which the display of the device is refreshed and to optimally adapt the settings of the server's browser.

Abstract: The present invention takes advantage of independent front-end and back-end processing schedules. On the back-end the data traffic is streamlined in order to optimize transfer speed, while on the front-end the user interface employs text boxes and other graphic-related resources to manage the display of information to the user. The user perceives the data entry as seamless and real-time, while the actual data transfer is restricted to the essential for the purpose of actual processing, which is performed by a remote server. The present invention thus reduces user perceived lag on data exchange with a remote server without requiring an actual increase on network transmission speed.
