| 20110175182 | Optical Seneor Package Structure And Manufactueing Method Thereof - An optical sensor package structure includes a substrate, a metal plate, an optical sensing chip, a plurality of bonding wires and a lens module. The substrate includes a top surface, a bottom surface and a hole penetrating the top surface and the bottom surface. The metal plate covers the hole from the bottom surface of the substrate. The optical sensing chip is received in the hole and mounted on the metal plate. The bonding wires interconnect the optical sensing chip and the top surface of substrate. The lens module is covering on the hole and mounting on the top surface of the substrate to enclose the optical sensing chip and the bonding wires. Because the optical sensing chip is received in the hole of the substrate, the height of the optical sensor package structure can be reduced to adapt to a compact size electrical device. | 07-21-2011 |

| 20090110515 | SCREW FOR USE IN NONMETAL OBJECTS - The present invention pertains to a screw for use in nonmetal objects comprising a plurality of cut-aiding portions formed by the longer and shorter cutting surfaces inclined toward opposite directions. Further, a cutting edge formed by the junction of any two adjacent cutting surfaces presents in a fastening direction of the screw. Thus, the cutting edge assists the threads to thoroughly severe and to shatter the fibers and debris of the objects, which can also be accommodated into the cut-aiding portions. Also, the ridge of the longer cutting surface aids in cutting fibers and further guides the debris out. In this manner, the present invention facilitates to enhance cutting capability for obtaining less screwing resistance, to prevent the destruction of the object and to increase the screwing speed. | 04-30-2009 |

| 20090265503 | Non-Volatile Memory Apparatus and Method for Accessing a Non-Volatile Memory Apparatus - A non-volatile memory apparatus and a method for accessing the non-volatile memory apparatus are provided. The non-volatile memory apparatus comprises a management unit, a look-up table and a controller. The management unit comprises a plurality of data blocks and a plurality of spare blocks. The look-up table is adapted to record the read status of the management unit. The controller is configured to read the management unit and then generate the read status denoting the times that the management unit has been read to the look-up table, and to replace one of the data blocks by one of the spare blocks in response to the read status when the times that the management unit has been read exceeds a reference value. | 10-22-2009 |

| 20090057931 | Tabletop Humidifier - A tabletop humidifier is disclosed which embodies one or more of low voltage operation from a high voltage supply through a current-limited transformer to provide a safely limited shock risk proximate to its water containing areas, tool-free and uncomplicated disassembly to enable end-of-life recycling of its components, and improved humidification efficiency through an inexpensive and reliable by-pass preventing means. | 03-05-2009 |
| 20090205498 | Air cleaner - An air cleaning apparatus including a housing defining an airflow passage, a blower retained by the housing and adapted when energized to move air through the airflow passage, a filter element disposed in the airflow passage and having an inlet surface for collecting particulate matter from the airflow. A nozzle element is adapted to engage the inlet surface and is connectable to a vacuum system for allowing the vacuum system to remove the particulate matter collected on the inlet surface. An emitter bathes the inlet surface with radiation to kill germs and detoxify impurities which collect thereon. The filter element is rotated relative to the nozzle element and emitter so that substantially all of the inlet surface is vacuumed and radiated. | 08-20-2009 |
| 20090290973 | TOWER FAN - An air blowing apparatus is disclosed having an elongate housing with an elongate scroll defining an airflow passage. An elongate blower is surrounded by the scroll and adapted when energized to move air through the airflow passage. The airflow passage is partially helically-shaped to cause the moved air to be distributed into the surrounding environment in a partially helical pattern. | 11-26-2009 |
