Abstract: A method for distance alert for a vehicle, the distance of the vehicle to obstacles in the vehicle's surroundings being detected. The output of an alert depends on whether or not an obstacle is located in the vehicle's travel path. If there is no obstacle located in the travel path, then an alert is only output at a substantially smaller distance than would be the case when an obstacle is located in the travel path. The method is used for avoiding unnecessary alerts about obstacles.

Abstract: A method and apparatus for powering one or more remotely-situated devices. In accordance with some embodiments of the invention, energy is added (at a convenient location) to a medium that the remotely-situated devices are associated with (e.g., a medium that the remotely-situated devices are sensing, controlling, alarming, etc). The energy is removed from the medium near to the remotely-situated devices. If required, the energy is converted to a form that is useable by the remotely-situated device. The removed energy is delivered to the remotely-situated devices and is used by them to perform an action that is associated with the medium (e.g., sensing a characteristic of the medium, controlling a characteristic of the medium, providing an alarm responsive to a value of a characteristic of the medium, etc.

The coupling apparatus/system generally includes one or more common mode chokes that feature a first winding and a second winding, the first winding being electrically connected between the first terminal of the power supply and the first electrical conductor of the network transmission medium, and the second winding being coupled between the first terminal of the power supply and the first electrical conductor of the network transmission medium. The common mode choke generally includes at least one core for coupling the first and second windings of the one or more common mode chokes. An RJ45 to 110 IDC modular connector may be connected to a printed circuit board used to transfer high speed signals for telecommunication interface media connections. The printed circuit board is configured to help reduce near-end crosstalk (NEXT) without compromising impedance.
Abstract: A power line communications technique (PLC) is disclosed which allows communications across any three phase electric system by modulating the impedance through earth between any two points of differing voltage on the electrical system in order to use the power supply as the communications power source thereby using the power supply current as the communications carrier. No additional coupled communications source is required and modulation of an earth link current at the power frequency is especially suitable for remote electrical loads, such as an oil well electric submersible pump, where it is most cost effective to only have the three power conductors and no neutral nor signal wires in the power cable. Embodiments of the invention are described.

The base of the container is arranged one of above a maximum filling level of the tank and substantially at the same level as the maximum filling level of the tank. A communication conduit is connected to each of the base of the container and an area of the tank which is in proximity to an upper portion of the tank. The system generates at least one warning signal after the tank is completely filled and when the container is partially filled by the communication conduit. This Abstract is not intended to define the invention disclosed in the specification, nor intended to limit the scope of the invention in any way.
Abstract: An intersection controlled by an intersection controller receives trigger signals from on-coming emergency vehicles responding to an emergency call. The intersection controller initiates surveillance of the intersection via cameras installed at the intersection in response to a received trigger signal. The surveillance may begin immediately upon receipt of the trigger signal from an emergency vehicle, or may wait until the intersection controller determines that the signaling emergency vehicle is in the field of view of the cameras at the intersection. Portions of the captured images are tagged by the intersection controller based on tag signals transmitted by the vehicle or based on detected traffic patterns that indicate a potential traffic violation. The captured images are downloaded to a processing facility that analyzes the images and automatically issues citations for captured traffic violations.

Abstract: Work tools such as a printhead, platen, and/or cutting head are spaced normally with respect to a media path based on a location of one or more objects carried by the media, and the position of the media with respect to the work tool. Additionally or alternatively the work tools are selectively operated based on a location of one or more objects carried by the media, and the position of the media with respect to the work tool. The approaches are suitable for the manufacture and use of RFID tags and labels.
Abstract: A position-tracking system for tracking the position of an object is disclosed. According to various embodiments, the tracking system includes a tracking device that is connected to or otherwise affixed to the object to be tracked. The tracking device may include, among other things, an inertial sensor assembly, radio transceivers and a processor. The position tracking system may also include a host processing system that is in communication with the tracking device. The position tracking system may provide variable-resolution position information based on the environment in which the object is moving. In a “wide resolution” area, the system may compute a general position for the object based on a wireless telephone network Cell-ID/map correlation architecture. In a high-resolution area, greater position resolution may be realized from the combination of a wireless aiding system and inputs from the inertial sensors.
Abstract: Methods and systems for electronically tracking the progress of teams as they cover an assigned geographic area are described herein. A server computer establishes a coverage area, divides the coverage area into a plurality of regions, and assigns each region to a team. Each team carries a tracking device capable of autonomously determining its present location without user assistance, thus allowing the team to focus on the assigned task, such as searching for a missing person, plowing a field, paving a road, etc. The server monitors the location of each tracking device as each team covers its assigned region, and updates on a visually displayed geographic map a historical path associated with each tracking device based on the monitored location of each tracking device. In this manner, users can quickly view the visual depiction of the historical to determine as yet uncovered areas.
Abstract: A bed monitoring system that remotely monitors a patient bed. The bed monitoring system comprises a bed status system and a master station. The bed status system is coupled to the patient bed and is configured to monitor at least one condition of the bed, and to generate a bed message indicating the status of the monitored condition. The master station, remote from the patient bed, is operatively coupled to the bed status system to receive bed status information. The bed message can include a bed identifier, bed type identifier, patient exit detection signal, bed occupied signal, or various other status signals. The system can also include locating stations that receive the bed messages from any beds within its monitored location, and generates a station message including information from the bed messages. The master station receives the station messages and can determine the status and location of any bed.

Abstract: An apparatus and method for generating incursion alerts in response to incursion events detected by incursion detector units, attached to safety icons such as traffic cones and signage. The incursion detector units are activated by automatic activation sensors and remain activated for a period of time. Alerts are generated in response to impacts detected at the safety icons by an incursion detector and transmitted to one or more incursion receiver units which annunciate the alert with audio, lights, or tactile output to warn personnel of possibly impending danger. Alert signals are preferably repeated by other incursion detectors wherein the distance and conditions over which the alert signals may be communicated is extended. A validation circuit and tilt sensor filter out not incursion events such as wind tipping. The incursion detectors may generate area alerts, or personal alerts and can transmit operational status and alerts to discrete groups of receivers.
