Sensor devices for structural health monitoring
Publication/Patent Number: US2002154029A1 Publication Date: 2002-10-24 Application Number: 10/115,872 Filing Date: 2002-04-03 Inventor: Watters, David G.   Huestis, David L.   Bahr, Alfred J.   Priyantha, Namal   Jayaweera, Palitha   Assignee: SRI International   IPC: H04Q009/00 Abstract: Described herein are wireless interrogation systems and methods that rely on a complementary sensing device and interrogator. The sensing device is disposed to measure a parameter indicative of the health of a structure. A sensor reading from the sensor indicates the level of a parameter being monitored or whether one or more particular physical or chemical events have taken place. Using wireless techniques, the interrogator probes the device to determine its identity and its current sensor reading. This often includes transmission of a wireless signal through portions of the structure. When activated, the device responds with a wireless signal that identifies the device and contains information about the parameter being measured or a particular sensor state corresponding to the parameter. The identity of the device allows it to be distinguished from a number of similar devices. Thus this invention finds particular usefulness in the context of an array of devices that can be probed by a wireless interrogation unit. In one embodiment, the devices are passive and derive power from the interrogation signal. Described herein are wireless interrogation systems and methods that rely on a complementary sensing device and interrogator.

Remote maintenance system and data processing system using electronic mail
Publication/Patent Number: US2002147806A1 Publication Date: 2002-10-10 Application Number: 10/112,702 Filing Date: 2002-04-02 Inventor: Hasegawa, Kiyoshi   Assignee: Yokogawa Electric Corporation   IPC: G06F015/173 Abstract: The present invention provides a remote maintenance system that eliminates the need for reconfiguring the network environment. In addition, the present invention is intended to solve the problem that the response of equipment becomes slower due to a delay in the timing for receiving emails when they arrive at higher frequencies since the interval of checking for arrival of any email addressed to the equipment itself is relatively long. The remote maintenance system for remotely configuring and maintaining target equipment comprises the target equipment to be remotely maintained and a command unit for sending emails containing commands to the target equipment through the Internet, wherein the target equipment executes a command contained in an email, so that the target equipment is configured and maintained. The remote maintenance system is designed so that when an email addressed to the target equipment arrives, the interval of checking for incoming emails is automatically shortened for a given period of time. In addition, if another email has arrived when the checking for incoming emails is performed at the shorter interval, the above-mentioned period of time is prolonged. As a result, it is possible to speed up the response of the target equipment and avoid imposing excess load on the mail server, or the like. The present invention provides a remote maintenance system that eliminates the need for reconfiguring the network environment. In addition, the present invention is intended to solve the problem that the response of equipment becomes slower due to a delay in the timing for ...More Less

System and method for managing a serial port
Publication/Patent Number: US2002147853A1 Publication Date: 2002-10-10 Application Number: 09/788,125 Filing Date: 2001-02-16 Inventor: Sherman, Roman   Shell, Scott R.   Assignee: Microsoft Corporation   IPC: G06F015/163 Abstract: The present invention provides for a virtual serial port (VSP) situated between a serial port in a mobile electronic device, applications that require a serial port connection handle, and other applications that require command-mode access to the serial port. Data-communication applications (e.g. web browsing, e-mail, etc.) connect to the serial port through the VSP. The VSP creates a virtual connection handle that is returned to the application. Command-mode requests (e.g., short messaging requests) are received by the hardware abstraction layer, translated into command-mode messages (e.g., AT commands) and placed in a queue. The VSP multiplexes the serial port between the currently-open data communication session (data-mode) and command-mode messages by periodically suspending the currently-open connection and processing one or more command-mode messages that are in the queue. A buffer continually stores incoming data while the data communication session is suspended. The VSP uses a heuristic calculation to determine the maximum time interval for which the data-communication session can be interrupted. The heuristic calculation takes a percentage of a time-quantum (e.g. 0.5 seconds) based upon the ratio of an average bit rate for air communication (e.g. 7000 bits/sec) and a bit rate for the serial port (e.g. 152,000 bits/sec). This ensures that data-communications are not interrupted for a time interval long enough to result in lost data-packets. The parameter for the time quantum and other parameters may be statically or dynamically adjusted to account for a finite buffer size in the hardware. The present invention provides for a virtual serial port (VSP) situated between a serial port in a mobile electronic device, applications that require a serial port connection handle, and other applications that require command-mode access to the serial port.
