Abstract: A diagnostic data collection device and a diagnostic data bus are disclosed. In an embodiment, the diagnostic data collection device includes a diagnostic communication interface and a flexible interface module. The interface module is configurable to measure one or more electrical properties associated with an HVAC component, such as voltage, current, resistance. Electrical properties may include a sensor output and may include analog and digital signals. The diagnostic data collection device generates an exception message if the sensed property is out of specification. Evaluation rules are provided to detect various types of failures, including transient failures, steady state failures, and trending failures. The diagnostic data collection device self-calibrates by recording electrical properties during normal operation of the HVAC equipment.

Abstract: A method and system for detecting and diagnosing faults in a heating, ventilation and air conditioning (HVAC) system includes a remote server receiving data from sensors associated with the HVAC system. The data received includes measured sensor data, from both HVAC equipment and co-located sensors, and identifying criteria for identifying the piece of equipment associated with the sensor and/or identifying a location of the sensor, which may or may not be on or in the HVAC equipment. A probability that a fault exists and/or a likelihood of occurrence of a fault in one of the pieces of the equipment is calculated based on the data received, and an alert is generated in accordance with an analysis thereof, which may include comparison of the probability and/or likelihood with predetermined threshold(s).

Abstract: Example apparatus and methods concern improved input of radicals. Example apparatus and methods facilitate more efficiently inputting Chinese radicals using a touch screen. One example method includes displaying a labeled soft key on a touch screen device. The label may represent all or a portion of a radical. The example method includes accepting a touch input associated with the soft key and then taking an action based on the label and the touch input. The action may include inputting a radical or updating the display on the touch screen. Updating the display may facilitate iterative and intuitive progress through radical construction leading to radical selection and input.

Abstract: An electroluminescent lamp comprises a substrate, an electroluminescent system printed on the substrate and a protection layer covering the outer surface of the electroluminescent system. The electroluminescent system comprises two electrode layers, where a dielectric layer and electroluminescent layer placed there between. The protection layer and the substrate interconnecting to form an envelope layer sealing the electroluminescent system, isolating the electroluminescent system inside the substrate and the protection layer. There is an adhesive layer beneath the substrate. It is also disclosed here a combination of an electroluminescent lamp and a metal dome sheet. There is a metal dome sheet beneath the adhesive layer. The metal dome sheet comprises a spacer where several receiving-grooves are provided and several metal domes seated respectively within the receiving-grooves. There is a second adhesive layer beneath the spacer. This invention has a simple structure and is easy to assemble.

Abstract: An apparatus and method for automatically offsetting the linear deviation of a V/F converter, the offset adjust pin of which is connected to a fixed resistance, and the frequency output pin of which is connected to a microcontroller unit (MCU) via an opto-isolator, a standard V/F transfer function being pre-stored in the MCU, wherein standard frequencies F1 and F0 (i.e., two coordination points (V1, F1) and (V0, F0)) are output by the V/F converter, when V1 and V0 are input as standard voltages, and the MCU may detect an error status in the V/F converter, when the V/F converter obtains real output frequencies F1? and F0? from real input voltages V1 and V2, and standard coordination points (F1, K1) and (F0, K0) will be corrected to (F1?, K1) and (F0?, K0?), from which a transfer function of offsetting frequency down is obtained, when the MCU processes a frequency down procedure.

Abstract: An integrated circuit (IC) has logic and timing circuits that are coupled to discrete circuitry to provide protection and indications whenever an AC adapter that is faulty or has improper voltage levels or polarity are plugged into a system. In particular, the IC device provides over-voltage, under-voltage, and reversed-polarity protections to an electronic system to keep the electronic system from being damaged by an alternating current (AC) adapter having an improper voltage range or voltage polarity. It also provides a protection that prevents an adapter from powering a host system that has a short-circuit fault.

Abstract: Dynamic sampling systems for fabrication with inspection control are provided. In embodiments of a fabrication system comprising a processing tool, inspection tool, and a controller, the processing tool performs a fabrication process on a workpiece associated with identification information. The inspection tool performs an inspection step on the workpiece. The controller, coupled to the processing and inspection tools, determines whether the processing tool corresponds to an inspection result obtained during a preset time period, and determines whether the workpiece is to be inspected by the inspection tool accordingly.
