The present invention is generally directed to a system for monitoring a variety of environmental and/or other conditions within a defined remotely located region. In one aspect, a system is configured to monitor utility meters (613) in a defined area. The system is implemented by using a plurality of wireless transmitters (614), each integrated into a sensor (612) adapted to monitor a particular data input. The system also includes a plurality of transceivers (221) that are dispersed throughout the region at defined locations. The system uses a local gateway (210) to translate and transfer information from the transmitters to a dedicated computer (260) on a network (230). The dedicated computer collects, compiles and stores the data for retrieval upon client demand across the network. The computer further includes means for evaluating the received information and identifying an appropriate control signal to be applied at a designated actuator.

System and method for monitoring and controlling remote devices

An adaptive interface for a programmable system, for predicting a desired user function, based on user history, as well as machine internal status and context. The apparatus receives an input from the user and other data. A predicted input is presented for confirmation by the user, and the predictive mechanism is updated based on this feedback. Also provided is a pattern recognition system for a multimedia device, wherein a user input is matched to a video stream on a conceptual basis, allowing inexact programming of a multimedia device. The system analyzes a data stream for correspondence with a data pattern for processing and storage. The data stream is subjected to adaptive pattern recognition to extract features of interest to provide a highly compressed representation that may be efficiently processed to determine correspondence. Applications of the interface and system include a video cassette recorder (VCR), medical device, vehicle control system, audio device, environmental control system, securities trading terminal, and smart house. The system optionally includes an actuator for effecting the environment of operation, allowing closed-loop feedback operation and automated learning.

Adaptive pattern recognition based control system and method

The Wireless Integrated Network Sensor Next Generation (WINS NG) nodes provide distributed network and Internet access to sensors, controls, and processors that are deeply embedded in equipment, facilities, and the environment. The WINS NG network is a new monitoring and control capability for applications in transportation, manufacturing, health care, environmental monitoring, and safety and security. The WINS NG nodes combine microsensor technology, low power distributed signal processing, low power computation, and low power, low cost wireless and/or wired networking capability in a compact system. The WINS NG networks provide sensing, local control, remote reconfigurability, and embedded intelligent systems in structures, materials, and environments.

A wireless machine monitoring and communication system includes one or more machine monitors (4a-m) which attach to one or more machines to sense a physical characteristic of the machine, such as vibration or temperature, and to produce wireless transmissions corresponding to the sensed characteristic. A command station (6) executes machine status polling in accordance with a time-division communication protocol and processes machine status data obtained during polling to determine the status of the machine. The machine monitor incorporates a wireless transmitter (430, 440) for transmitting at least status information, and the command station (6) incorporates a wireless receiver (618) for receiving monitor transmissions. To conserve power, the machine monitors (4a-m) are turned on only at preprogrammed times in accordance with the time-division communication protocol. Each machine monitor (4a-m) includes a receiver (430) and the command station (6) includes a transmitter (604) to enable the command station to send commands to each machine monitor. A microcomputer (418) in each monitor analyzes sensor data and a memory (422) stores the analyzed sensor data. Repeaters (8a-e) are employed as necessary to assist in propagating wireless transmissions throughout the system. A tachometer sensor (5a-c) is employed at each machine to provide monitors and sensors with information relating to machine speed. A computer network (10) is connected to the command station (6) for transferring data and for controlling the overall operation of the system.

Wireless machine monitoring and communication system

A hand held data collector and analyzer achieves superior stability, accuracy and reliability through the use of a fixed frequency anti-aliasing filter and two analog to digital converters, one for high frequency signals and one for low frequency signals. Efficient digital filtering and decimation is achieved by providing specialized hardware filters and decimators and implementing software filters and decimators in a data processor. A true zoom method is employed to take advantage of the filtering and decimation capabilities, and independent digital signal processors operate serially on incoming signals to further reduce demands on the central processing unit. In addition, the RAM system memory is formatted as a pseudo-card to facilitate use of a PCMCIA memory card or the RAM system memory.

Hand held data collector and analyzer system

A method of configuring and synchronizing a wireless machine monitoring system that has at least one chain, that includes at least one machine monitor and at least one repeater is disclosed. The wireless machine monitoring system may further include a master repeater that is in communication with the chain and a command station that is in communication with the master repeater. The wireless machine monitoring system is configured so that only one element of the system is communicating at any given time. In addition, bit error rate transmission tests are performed on the elements of the system to determine their ability to communicate at different transmission power levels. Thus, power consumption of battery powered elements is minimized by decreasing the amount of time the devices are active and by configuring the communicating elements to transmit at the lowest acceptable power level. An installation and configuration unit is provided for installing and configuring the machine monitors and the repeaters within each chain of the wireless machine monitoring system.

Method and apparatus for configuring and synchronizing a wireless machine monitoring and communication system

A zoom processor for increasing the resolution of a band of interest within an acquired analog time domain frequency signal. The signal is converted from an analog time domain signal to a digital time domain signal. Next, the signal is multiplied by a value which will lower the center frequency of the band of interest to zero. The value by which the signal is multiplied is based on both the sine and cosine of a function of the center frequency and the sampling frequency used to digitize the signal. The sine function is solved with the aid of a numerical substitution which simplifies finding the value of the function in a sine table. After the signal is shifted, it is low-pass filtered, which removes all of the signal except the band of interest. During filtering, the band is also decimated by a predetermined factor, which compresses the time domain signal, and proportionally expands the frequency domain signal which is produced at a later step of the method. A transform, such as a Fast Fourier Transform, is performed on the band, to convert the signal from time domain to frequency domain. The signal is analyzed according to the ultimate function of the instrument in which the zoom processor is incorporated.
