Described are techniques for generating, updating, and using sensor-based navigational maps. An input map is generated based on sensor data captured by a first sensor of a first vehicle. The input map is filtered based on one or more criteria to generate a filtered map corresponding to a three-dimensional representation of a route traveled by the first vehicle. The filtering can be based on detecting features using sensor data captured by a second sensor of the first vehicle. The one or more criteria can include object classes, distance criteria, and/or other criteria relating to attributes of features in the sensor data captured by the first sensor and/or the sensor data captured by the second sensor. The filtered map can be stored for transmission to a second vehicle, for use in determining a location of the second vehicle while the second vehicle is traveling along the same route.

A method of determining changing well characteristics at downhole locations based on changes in detected temperatures by permanently installed downhole sensors. The methods and tools utilized involve the establishing of baseline temperature profiles, for example, at the outset of well operations. The installed sensors may be powered are rechecked on a periodic or continuous basis for substantial deviations to the temperature profiles which are indicative of particular well condition changes such as the depositing of asphaltene or decreases in fluid velocity.

A thermal sensor may include a housing having a thermal contact member, an indicator coupled to the housing, and a thermal sensing element disposed in the housing in thermal communication with the thermal contact member. The thermal sensor may also include an actuator element in communication with the indicator and thermal sensing element. The thermal sensing element may be configured to expand in response to reaching a temperature threshold thereby engaging the actuator element and activating the indicator.

A processing apparatus and a method capable of accurately measuring a real temperature of a workpiece contained and heated in a chamber. The processing apparatus includes a chamber containing a workpiece, a measurement piece installed in the chamber, and a measuring unit. The measurement piece is capable of thermal expansion and contraction in response to an internal temperature of the chamber. The measuring unit measures a thermal expansion and contraction amount of the measurement piece to thereby measure the real temperature of the workpiece.

A method of detecting thermal hotspots in a power distribution system is provided. The power distribution system includes a conductive hub including a connection point for coupling to an electrical distribution component. The method includes measuring a first temperature of the conductive hub at the connection point, estimating a second temperature of the conductive hub at the connection point, and determining when a difference between the first temperature and the second temperature exceeds a first predetermined threshold. The estimation based at least partially on an amount of electric current flowing through the conductive hub.

A fixing apparatus includes a first rotary member, a nip forming member, a second rotary member, a heating element, a temperature detection element, a holder configured to hold the temperature detection element, and an urging member configured to urge the holder toward the nip forming member to bring the holder into contact with the nip forming member. The holder includes a base member configured to receive an urging force from the urging member, and a head member to which the temperature detection element is attached, the head member being configured to be in contact with the base member and tiltable with respect to the base member. The head member is configured to be urged toward the nip forming member by the urging force and to tilt following a portion of the nip forming member opposing the head member.
