System and method for automated placement or configuration of equipment for obtaining desired network performance objectives and for security, RF tags, and bandwidth provisioning

A method is presented for determining optimal or preferred configuration settings for wireless or wired network equipment in order to obtain a desirable level of network performance. A site-specific network model is used with adaptive processing to perform efficient design and on-going management of network performance. The invention iteratively determines overall network performance and cost, and further iterates equipment settings, locations and orientations. Real time control is between a site-specific Computer Aided Design (CAD) software application and the physical components of the network allows the invention to display, store, and iteratively adapt any network to constantly varying traffic and interference conditions. Alarms provide rapid adaptation of network parameters, and alerts and preprogrammed network shutdown actions may be taken autonomously. A wireless post-it note device and network allows massive data such as book contents or hard drive memory to be accessed within a room by a wide bandwidth reader device, and this can further be interconnected to the internet or Ethernet backbone in order to provide worldwide access and remote retrieval to wireless post-it devices.

Home automation system and method

A home automation system and method for automatic control of controlled devices throughout a home. A unique architecture of occupancy sensors includes entry/exit sensors for detecting movement through doorways that separate rooms in the home, room motion sensors for detecting room occupancy, spot sensors to detect occupancy of specific locations within the rooms, and house status sensors to detect the status of certain parameters of the home. A central controller communicates with the sensors and controlled objects over a communications network, where the sensors and controlled objects can be added to the system in a ‘plug and play’ manner. The central controller controls the controlled objects in response to the entry/exit sensors, room motion sensors, spot sensors and the house status sensors. This control is accomplished by assigning each room to one of a plurality of room occupancy states, and to one of a plurality of room modes for creating desired room atmospheres using the controlled objects, which both dictate how the controlled objects are controlled by the central controller. The room modes travel from room to room as the occupant moves throughout the home, and multiple occupants can be using different room modes as they move about the home. The controlled objects also have controlled object states, which are used by the central controller to control the controlled objects.

Methods and systems for calibration of RFID sensors

ActiveUS20090278685A1Testing sensing arrangementsGas analyser calibrationMemory chipComplex impedance spectra
Methods and systems for calibration of RFID sensors used in manufacturing and monitoring systems are provided. The methods include measuring impedance of an RFID sensor antenna, relating the measurement of impedance to one or more parameters (such as physical, chemical and biological properties), computing one or more analytical fit coefficients, and storing the one or more analytical fit coefficients on a memory chip of the RFID sensor. Measuring impedance of the RFID sensor may comprise measuring complex impedance which involves measuring complex impedance spectrum, phase angle and magnitude of the impedance, at least one of frequency of the maximum of the real part of the complex impedance, magnitude of the real part of the complex impedance, zero-reactance frequency, resonant frequency of the imaginary part of the complex impedance, and antiresonant frequency of the imaginary part of the complex impedance. Also provided are manufacturing or monitoring systems comprised of an RFID sensor wherein the RFID sensor comprises, a memory chip, an antenna, and a sensing film wherein analytical fit coefficients are stored on the memory chip to allow calibration of the RFID sensor. Also provided are manufacturing or monitoring systems comprised of an RFID sensor wherein the RFID sensor comprises, a memory chip, an antenna, and a complementary sensor attached to the antenna where the complementary sensor in a pre-calibrated fashion predictably affects the impedance of the antenna.

Bed exit and patient detection system

A bed exit and patient detection system especially adapted for use in the general medical or surgical floor area of a hospital or other healthcare facility as part of a vital signs monitoring and remote warning system includes a plurality of pressure sensors disposed in the patient's bed in a series of rectangular strips or zones that run laterally across the bed in the area of the patient's mid-back, hips and mid-legs, respectively. Each zone contains a plurality of sensors, arranged symmetrically about the centerline of the bed, with the corresponding sensors on opposite sides of the centerline in each zone being connected in parallel. The sensors are connected to a processor with multiple input channels that continuously monitors the sensor states to determine, from the pattern of sensor states observed, whether the patient is in bed, out of bed or is actively attempting to ext the bed at the sides or foot of the bed. At least three different sets of bed exit logic rules are available for user selection to configure the system for high, medium or low sensitivity, or bed exit privileges, for any particular patient. In some embodiments, the system also is capable of detecting when a patient is attempting to assume certain prohibited in-bed positions, such as sitting positions or slumping positions. An alarm in the form of a pre-recorded voice announcement or an alarm over a pre-existing nurse call system is provided when the sensor states are indicative of an out-of-bed or an exiting bed condition, or other prohibited in-bed positions, for a predetermined minimum period of time.

Security control and communication system and method

An integrated security control system and method which integrate the functions of a wireless security system control panel and a radio transceiver in an integrated security control system unit. The integrated control unit includes a first telephone communication system for communicating security system data by wired telephone communications, and a second radio frequency (RF) cellular communication system for communicating security system data by communications through an RF communication network. The cellular communication system is the primary communication network for reporting a security event, thereby leaving the first telephone communication system open for telephone communications during the reporting of a security event. A separate unit of the security system, such as a wireless RF status display or a wireless RF keypad, is provided with a beeper transducer for sounding entry and exit beeps. The separate unit is positioned at a separate location from the integrated security control system unit, such that the entry beeps do not alert an entering person to the location of the integrated security control system unit. When a security event is triggered, the control unit delays activating a security alarm sounder in the control unit until after the second RF communication system has finished transmitting the alarm message.
