Abstract: A remote monitoring system, particularly useful in monitoring the position of a child or Alzheimer's patient, has a first unit including a handheld portable transmitter and receiver; and a second unit including two identical sections, wherein each section is carried in one of a footwear pair, and each section has a transmitter and receiver. The transmitter of the first unit has a selective switch for on-demand transmission of a find signal. The transmitters of the second unit each continuously emits a location signal. The receiver of the first or handheld unit is responsive to one of or both location signals. The handheld unit generates an audible alarm indicating that the person wearing the footwear has gone beyond a preset distance from the first or handheld unit.

Abstract: A method and apparatus for alerting personnel in response to an alarm from an automated system. The monitoring system detects an alarm. Upon detection of the alarm, the monitoring system searches a list. The list includes contact numbers, wherein each contact number has a corresponding contact person, delay time, and a contact day and time for when each contact number should be used. A current day and time is matched with a contact day and time from the list. Upon a successful match, a contact person corresponding to the matched contact day and time is notified using a contact number corresponding to the matched contact day and time. If after a delay time corresponding to the matched contact day and time the alarm is not reset, a next contact number from the list having a contact day and time matching the current day and time is used to notify a contact person corresponding to the next contact day and time. A next contact number is selected and used from the list until the alarm is reset.

Abstract: A computer system processes physiological data signals provided by a physiological-condition monitoring system to determine whether the person may have suddenly experienced fear by comparing the monitored physiological data with stored stress profile data for the person that is based upon measurements of the monitored physiological conditions of the person during situations of stress and/or upon statistical classification in view of a combination of predetermined characteristics of the person. When such processing by the computer system determines that the person may have suddenly experienced fear, the computer system activates an alarm indicator. The computer system includes a neural network for modifying the stored stress profile data in response to an input signal indicating that the computer system provided a false alarm indication. The surrounding conditions that may have caused the determination of probable fear are recorded and transmitted to a remote location.

Abstract: Eyeglasses hold a light sensor (1) positioned to receive light reflected from an eye. An electronic comparator circuit (4) uses variations of current through the sensor which occur during blinking and eye movement to produce pulses which reset an electronic timing cycle, thereby continually delaying the activation of an alarm signal (8). In the absence of eye motion for a predetermined period of time a warning tone is sounded in the preferred embodiment, followed by a full volume alarm if needed to wake a sleeping driver.

Abstract: A switch including a mass suspended above a base by a flat horizontal spring has electric contacts that close in response to the initial shocks of major earthquakes and activates safety devices before the onset of destructive ground motions. The vertical unidirectional seismic switch can be manufactured by micromechanical photolithography and is integrated with electromechanical safety devices to latch cabinets closed, secure movable objects, shut off gas, water, and electric utilities, activate alarms, early warning networks, and related automated response systems. The device is fully self contained, consumes no power until activated, is inexpensive to produce, and impervious to nonearthquake noise in that it is designed to respond specifically to the vertical acceleration and displacement characteristic of the initial shock waves of a major earthquake.

Abstract: The invention relates to a special type of magnetic tag that serves both as an identifier of the article to which it is attached and as an antitheft device. Identification comes about through the use of an array of individual magnetic elements that are closely spaced, preferably along and perpendicular to an amorphous wire or strip. The wire or strip forms an integral part of the identification array and can be used as an anti-theft device to trigger an alarm when activated by an external field from a magnetic gate. The array may be personalized (coded) by leaving out elements of the array or by driving selected elements to saturation while others remain demagnetized. The elements can also be in the form of a double array to constitute `l`s and `0`s to form a code. Reading of the elements (code) is accomplished with a special reading head consisting of one or more small magnetic circuits coupled to one or more pickup loops utilizing, in some cases, the Matteucci effect.

Abstract: An inclination sensor is disclosed. The sensor includes two temperature controlled inclination devices that are mounted orthogonal to each other. The inclination devices include an oven, a resistive element attached to the oven, an inclination transducer mounted in the oven and a thermistor being mounted to the oven. The thermistor produces a signal representative of the actual temperature of the oven. A microprocessor receives the actual temperature signal of each inclination device and produce heating signals to energize the corresponding resistive elements to control the temperature of the respective ovens to a desired temperature.

Abstract: A material used to form a biasing element for a magnetomechanical EAS marker has a coercivity that is lower than the coercivity of biasing elements used in conventional magnetomechanical markers. The marker formed with the low coercivity material can be deactivated by applying an AC magnetic field at a level that is lower than is required for deactivation of conventional markers. The marker with the low coercivity bias element can also be deactivated when at a greater distance from a deactivation device than was previously practical.

Abstract: A multiple sensor smoke detector includes at least an ionization and a photoelectric sensor. Outputs from the sensors are fed to circuitry for generating continuously variable coefficients.

Abstract: A method of electrically connecting an integrated circuit (IC) to at least one electrical conductor on a flexible substrate. A flexible dielectric substrate has an IC attachment area and at least one resonant circuit formed thereon. The resonant circuit is formed with a first conductive pattern disposed on a first principal surface of the flexible substrate and a second conductive pattern disposed on a second, opposite principle surface of the flexible substrate. The first conductive pattern is electrically connected to the second conductive pattern such that the first and second conductive patterns form an inductor and a capacitor, with the inductor also functioning as an antenna. The IC attachment area of the flexible substrate is cleaned and the flexible substrate is secured in a fixed position in a plenum to prevent substantial movement thereof. The IC is secured to the IC attachment area of the flexible substrate to minimize movement of the IC relative to the flexible substrate.

Abstract: A glazing unit has a tempered glass pane or other frangible glazing pane carrying a glazing pane breakage detector assembly. The detector assembly includes spaced first and second electrically conductive bus pads formed of electrically conductive material on a surface of the glazing pane. An electrically resistive trace on the surface of the glazing pane is formed of electrically resistive material different from the electrically conductive material of the bus pads. The resistive trace establishes a non-short electrical interconnection between the bus pads, which can be formed of highly conductive material, such as silver-filled paint currently in widespread commercial use. Such bus pads afford a structurally sound attachment, with good electrical contact by soldering, electrically conductive epoxy or the like upon which upstanding attachment tabs are secured. Electrical leads can be attached to such upstanding tabs to connect the detector assembly to suitable security circuitry.
