Abstract: An absorbent article is provided herein that comprises a first layer with at least two conductive lines being provided thereon along and throughout its length, and a second porous layer overlaying the first layer. Conductive material is applied onto the second porous layer such that the conductive material impregnated into the second porous layer connects the conductive material on the top surface of the second porous layer to the conductive lines on the first layer.

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. Also, with increasing volume of moisture, the resistance of the closed circuits also tends to decrease. This rate of decrease of resistance is also detected by the detecting device and is used to calculate a volume of moisture present in the diaper. The detecting device then generates a suitable alarm to give an idea about the saturation level of the diaper. The process of manufacturing sensing elements by spraying conductive inks on moving sheet of layer reduces the processing and modification overhead of specially designed conductive ink printers and also does not impact the manufacturing time of a diaper manufacturing assembly line.

Abstract: A system for sensing wetness in an ordinary diaper includes a disposable sensor unit which has a sensor strip and 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 urine and also keeps the conductive elements at a specific height from the diaper's padding such that urine content retained by a soaked diaper do not raise alarms.

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 present invention discloses a solar concentrator for supplying energy. Sunlight is redirected by a concentrating reflector toward a target area, whereat concentrated sunlight is collected and converted by a solar panel. As the target area changes position based on daily and seasonal solar movement, the position of the solar panel is adjustable to track the target area. The solar panel is guided by a repositioning mechanism, and both the repositioning mechanism and the solar panel are supported by a mechanical structure. The present invention discloses various embodiments for the repositioning mechanism and mechanical structure to enable tracking the target area two-dimensionally with minimal efficiency losses.

Abstract: A head mounted display device is capable of providing user a type of augmented reality (AR) experience with private access of the augmentation elements as represented by computer-generated (CG) contents. The core of the device comprises an optical combiner and a layer of photochromic materials or other means alike that changes from transparent to opaque when subjected to appropriate conditions, such that an occlusion mask pattern occupying a small portion of the said layer is created with dimension and position correspond to the CG content. The device allows user to selectively conceal the CG content from the surrounding people while keeping a sight of the real world whose elements are augmented or supplemented.

Abstract: A system for sensing wetness in an ordinary diaper comprises a disposable sensor strip that adhered to a diaper's padding, and a portable yet non-disposable alerting device. The sensor strip has electrical circuit with conductive elements as wetness sensors, wherein a closed electrical circuit is formed when an amount of body fluid is present that subsequently triggers the alerting device. The sensor strip is electrically coupled to the alerting device with a portion wrapped around the alerting device, wherein the position of the wrapped portion is secured by the indentation or ribs around the outer surface of the alerting device. Locations of the adhesives on the sensor strip are designed in a way that the alerting device is fastened to the outer surface of the diaper without skin contact to the wearer and without contact to any adhesive, such that the alerting device is ready for immediate reuse.
