Abstract:
Apparatus, systems, and methods for providing transmission and localized reception of data, aural, visual, and tactile signaling are taught for a myriad of useful purposes, including embodiments that permit differentiation between selected groups of intended recipients to permit simultaneous use of multiple instances of this technology in close proximity, if desired.
Abstract:
A method comprises: receiving a signal from a first device that is part of a tag, the tag adapted to be affixed to a person or object, the receiving being performed by a processor within the tag; analyzing the signal within the processor to determine whether the person or object is performing a predetermined type of behavior; adjusting a variable rate of transmitting a monitoring signal from the tag, based on a result of the analyzing, the adjusting being controlled by the processor; and transmitting the monitoring signal from the tag to an external device separate from the tag at the adjusted variable rate.
Abstract:
Systems (100) and methods (400) for powering an electrical load (322) in an environment. The methods involve using a battery (310) to simultaneously supply electrical energy to control electronics (308, 316) and a Super Capacitor ("SC") storage element (314) immediately after a system has been disposed in the environment and turned on. In effect, the control electronics are caused to perform intended functions thereof nearly instantaneously after turning on the system. The SC storage element is charged from a first charge state in which approximately zero volts exist across terminals thereof to a second charge state in which greater than zero volts exists across the terminals. The SC storage element is then used to supply electrical energy to the electrical load of the system so as to cause the electrical load to perform intended functions thereof.
Abstract:
A position sensing system and method for detecting the displacement of a door from a reference position, such as, for example, from a closed position. The system includes a magnetometer that may be operably connected to the door, and which measures positional location relative to a reference magnetic field, such as, for example, a magnetic field provided by a magnet of a lock device. The system may also include an accelerometer that detects acceleration of the door, and thereby provides an indication of when location is to be measured by the magnetometer. Measurement information from the magnetometer is used to derive a position indicator that is compared to a reference indicator, the reference indicator being associated with the reference position. Differences between the position and reference indicators may provide an indication that the door has been moved from the reference position.
Abstract:
An environmental monitoring device that includes an imaging device is described. During operation of the environmental monitoring device, the imaging device provides imaging data for an external environment that includes the environmental monitoring device. Moreover, the imaging device has different spatial sensitivity in different regions of the external environment, which defines a field of view of the imaging device. For example, the imaging device may include a lens with a predefined distortion that provides the different spatial sensitivity, such as Fresnel lens. Alternatively, a mechanical stop may provide the different spatial sensitivity. Furthermore, the environmental monitoring device may include an angular adjustment mechanism that, in response to an external force or a control signal from a control mechanism in the environmental monitoring device, selectively rotates about an axis to change an orientation of the field of view.
Abstract:
The present invention provides a monitoring system having an alarm base and one or more remote sensors and data collecting devices. The alarm base and remote sensors communicate over a wireless connection and use a frequency hopping technique to implement a highly efficient communication protocol. By predefining and fixing both hop channels and ordering, the system is able to operate with reduced power demand. The communication protocol has very low power requirements in the alarm base and even lower power requirements in each of the remote sensors. The communication protocol is robust providing 100% data communications even at the edge of range,
Abstract:
This invention is an alarm apparatus (100) for detecting radiation and/or pollutants including smoke and carbon monoxide. The apparatus comprises an alarm circuit including detection means for detecting the radiation and/or pollutants and an audible alarm emitting device(102). A power supply circuit(A, B), connectable to an external AC power supply,supplies power the alarm circuit. A controller (60) operates the power supply circuit (A, B) in a first mode of operation in which it supplies current to the alarm circuit (52) at a first level less than that required to energise the audible alarm emitting device (102) and, in response to the detection of radiation and/or pollutants, operates the power supply (A, B) in a second mode of operation in which it supplies current to the alarm circuit (56) at a second level sufficient to energise the audible alarm emitting device (102).
