摘要： A method for manufacturing low cost electroluminescent (EL) lamps is disclosed. The method of the present invention includes the first step of die cutting, embossing or chemically etching the metal foil surface of a metal foil bonded flexible electrical insulation to simultaneously form one or more rear capacitive electrodes, electrical terminations, optical registration fiducial indicia, and a continuous carrier means that is then coupled to a precisely positioned indexing system. Next, the rear metal foil capacitive electrodes are coated with a capacitive dielectric layer precisely isolating the rear electrode form. In the third step, a layer of electroluminescent phosphor ink is applied to the rear capacitive electrodes to precisely form areas of illumination. In step four, a layer of light transmissive and electrically conductive ink is applied to cover the EL phosphor layer. Next, in step five a transparent polyester film or ultraviolet activated dielectric coating is applied to the entire surface of the lamp.

摘要： An integrated efficient fan controller circuit device for controlling a fan of a heating, ventilating and air conditioning (HVAC) system, comprising an input-output port, a voltage regulator, a microprocessor, and a transistor wherein the transistor turns on the microprocessor that sends a trigger signal to the gate of a triac which controls the fan of an HVAC system to switch OFF the HVAC fan operation when the thermostat fan output is in float or unknown state. The proposed circuit avoids the floating state of the thermostat fan output and keeps the HVAC fan either in ON state or in OFF state. The transistor acts as a switch and the collector of the transistor is connected to the input terminal of microprocessor which controls the triac operation. The microprocessor measures the real time temperature of the system and controls the operation of the HVAC fan. The present invention handles the switching OFF of the HVAC fan operation when the thermostat fan is switched to OFF.

The method includes the first step of die cutting, embossing or chemically etching the metal foil surface of a metal foil bonded, light transmitting flexible electrical insulation to simultaneously form one or more front capacitive electrodes, membrane switch contacts and electrical shunt, electrical distribution means and electrical terminations that together comprise a flexible printed circuit panel. This continuous flexible printed circuit substrate is then coupled to a precisely positioned indexing system. Next, the front metal foil capacitive electrodes arc coated with a light transmissive electrically conductive layer. Then, a layer of electroluminescent phosphor is applied to the electrically conductive layer, a layer of capacitive dielectric is applied insulating the phosphor layer, a rear capacitive electrode is then applied over the capacitive dielectric layer, thus forming an electroluminescent lamp portion. Next, a transparent dielectric coating is applied to the entire surface of the lamp and substrate with open portions exposing electrical terminations, switch contacts and shunt. A spacer is applied to surround the switch shunt, providing an isolation barrier. An intermediary material is applied to the surface of the isolated rear EL electrode thus forming a switch actuator. Finally, the illuminated switch pattern is die-cut from the substrate material, and is then folded into three layers forming the final illuminated membrane switch.

摘要： A method is disclosed for integrating a file system with a RAID array that exports precise information about the arrangement of data blocks in the RAID subsystem. The file system examines this information and uses it to optimize the location of blocks as they are written to the RAID system. Thus, the system uses explicit knowledge of the underlying RAID disk layout to schedule disk allocation. The method uses separate current-write location (CWL) pointers for each disk in the disk array where the pointers simply advance through the disks as writes occur. The algorithm used has two primary goals. The first goal is to keep the CWL pointers as close together as possible, thereby improving RAID efficiency by writing to multiple blocks in the stripe simultaneously. The second goal is to allocate adjacent blocks in a file on the same disk, thereby improving read back performance. The method satisfies the first goal by always writing on the disk with the lowest CWL pointer. For the second goal, a new disks chosen only when the algorithm starts allocating space for a new file, or when it has allocated N blocks on the same disk for a single file. A sufficient number of blocks is defined as all the buffers in a chunk of N sequential buffers in a file. The result is that CWL pointers are never more than N blocks apart on different disks, and large files have N consecutive blocks on the same disk.

摘要： A method is disclosed for maintaining consistent states of a file system. The file system progresses from one self-consistent state to another self-consistent state. The set of self-consistent blocks on disk that is rooted by a root inode is referred to as a consistency point. The root inode is stored in a file system information structure. To implement consistency points, new data is written to unallocated blocks on disk. A new consistency point occurs when the file system information structure is updated by writing a new root inode into it. Thus, as long as the root inode is not updated, the state of the file system represented on disk does not change. The method also creates snapshots that are user-accessible read-only copies of the file system. A snapshot uses no disk space when it is initially created. It is designed so that many different snapshots can be created for the same file system. Unlike prior art file systems that create a done by duplicating an entire inode file and all indirect blocks, the method of the present invention duplicates only the inode that describes the inode file. A multi-bit free-block map file is used to prevent data referenced by snapshots from being overwritten on disk.

摘要翻译： 公开了一种用于维持文件系统的一致状态的方法。 文件系统从一个自我一致的状态进展到另一个自我一致的状态。 由根inode生成的磁盘上的一组自相关块被称为一致性点。 根inode存储在文件系统信息结构中。 要实现一致性点，新数据将写入磁盘上的未分配块。 当通过在其中写入新的根节点来更新文件系统信息结构时，会发生新的一致性点。 因此，只要root inode不被更新，在磁盘上表示的文件系统的状态就不会改变。 该方法还创建快照，这些快照是文件系统的用户可访问的只读副本。 快照在最初创建时不使用磁盘空间。 它的设计使得可以为同一个文件系统创建许多不同的快照。 与通过复制整个inode文件和所有间接块创建完成的现有技术文件系统不同，本发明的方法仅复制描述了inode文件的inode。 多位自由块映射文件用于防止快照引用的数据被覆盖在磁盘上。

摘要： The ionizer feedback control converts high-voltage signals to feedback signals to monitor the corresponding high-voltage signals and compares the feedback signals to a first specification to determine whether the feedback signals are within the first specification. The ionizer varies a frequency and a duty cycle of a digital signal to control an excitation signal for a step-up transformer and modulates the frequency and the duty cycle of a step-up transformer output voltage to consistently maintain the feedback signals within the first specification and maintain the high-voltage signals within a second specification to generate consistent ion concentrations over a range of electrical signal inputs. The microprocessor calculates and reports high-voltage signals, and ion concentrations based on feedback signals. The microprocessor monitors concentrations of Volatile Organic Compounds (VOCs) in an airflow serving the ionizer and adjusts the high-voltage signals and ion concentration when VOC concentrations are above a threshold.
