Abstract: Trench-confirmable geothermal reservoirs with flexible reservoir bodies that can snugly abut trench walls (that may be of virgin, compacted earth) for facilitating heat exchange and flow liquid from one lower end to an opposing top end, and vice versa, depending on desired heat exchange. The direction can be reversed for summer and winter heat/cooling configurations. A series of the reservoirs may be used for appropriate heat transfer. The water volume of the reservoirs is relatively large and slow moving for good earth heat conduction. The reservoirs include first and second ports, one of which has an elongate internal tube that has a bottom that resides adjacent a bottom of the reservoir body and a series of apertures on only a lower portion of the internal tube to intake or output liquid depending on flow direction.

Abstract: A method for tracking insured assets is provided. Asset identifiers corresponding to assets to be monitored are received from a user. Each of the one or more assets is attached to a tracking device. Monitored assets are covered by one or more insurance policies. One or more geofence regions are defined associated with the one or more monitored assets. A location of each of the monitored assets is estimated, at least periodically. In response to determining that the estimated location of at least one of the monitored assets is outside of the corresponding one or more geofence regions, an insurance policy associated with this at least one asset is determined. A policyholder associated with the insurance policy is notified by sending a notification to policyholder's-preferred device. The notification inquires instructions for remedial actions from the policyholder. One or more remedial actions are initiated based on received policyholder's instructions.

Abstract: A ragger system for removing solid debris from a pulper vessel of a pulping system is disclosed. The ragger system includes a ragger operable to pull a tail of solid debris from the pulper vessel. The ragger includes a puller mechanism, a puller drive, a rider roll, and a pressure device to adjust a pressure of the rider roll on the tail between the puller mechanism and the rider roll. The ragger system includes a measurement device for determining attributes of the tail, operating conditions of the pulping system or ragger, or combinations of these. The ragger system includes a control system that measures input variables with the measurement devices, determines the attributes of the tail or operating conditions from the input variables, and adjusts a withdrawal rate, pull direction, pressure, rider roll torque or speed, or combinations thereof to maintain continuity of operation of the ragger.

Abstract: In a method for producing a thermal component (1, 1?) a pipe (2, 2?,2?) having a fluid channel (3, 3?, 3?) with an inner profile (4, 4?) is provided, and a swirler (6, 6?) having an outer profile (5, 5?) corresponding to the inner profile (4, 4?) is inserted into the fluid channel (3, 3?, 3?).

Abstract: An arc fault detection system samples a high frequency signal on a power line sequentially at different frequency regions according to a frequency hopping sequence, which is repeated a number of times over a predefined period. The different frequency regions include at least one region with a carrier for power line communication on the power line and at least one region without a carrier for power line communication on the power line. The system obtains energy measurements for each frequency region based on the sampled signals, computes an energy level for each frequency region based on the measurements for each region, and assigns a binary value to each region according to the corresponding energy level. The binary value represents a presence or absence of signal content in the frequency region. The system determines a presence or absence of an arc fault based on the binary values for the frequency regions.
