Abstract: A mount for a remote camera for use with a jack. The remote camera is wirelessly coupled to a processor-based device, and contained within a housing that is rotatably coupled to a base mounted to a surface, or is integrated within a control box of the jack.

Abstract: A method of heating a subsurface hydrocarbon containing formation includes providing heat flux per volume to a first portion of a subsurface hydrocarbon containing formation. The heat flux per volume is provided by two or more first heat sources positioned in the first portion. Heat flux per volume is provided to a second portion of the subsurface hydrocarbon containing formation with the heat flux per volume being provided by two or more second heat sources positioned in the second portion. The heat flux per volume provided by the two or more second heat sources is greater than the heat flux per volume provided by the two or more first heat sources. The second portion is positioned below the first portion.

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.
