A dilatometer configured to measure dilation of an electrode in a battery. The dilatometer including a controller configured to: receive calibration force readings from a magnetic force sensor, the calibration force readings including magnetic force strength between a magnet of the dilatometer and a magnetic spacer of the battery at different calibration distances resulting from movement of the magnet relative to the magnetic spacer across a distance range during calibration; assign a position value to each one of the calibration force readings, the position value is a distance between the magnet and the magnetic spacer of the battery; and predict magnetic force strength between the magnet and the magnetic spacer across an entirety of the distance range based on the position values of the calibration force readings.

A method for using idle computing power of an electric vehicle includes receiving computing tasks while the electric vehicle is electrically connected to a charging infrastructure, accepting to perform the computing tasks while the electric vehicle is electrically connected to the charging infrastructure, and in response to accepting to perform the computing tasks, performing the computing tasks while the electric vehicle is electrically connected to the charging infrastructure.

Method and system for using idle computing power of an electric vehicle

A method for using idle computing power of an electric vehicle includes sending the computing tasks and the task rates for performing the computing tasks to a vehicle controller of the electric vehicle and receiving an acceptance signal from the vehicle controller. The acceptance signal is indicative that the vehicle controller accepted to perform the computing tasks. The method further includes commanding a charging infrastructure to supply electrical power the electric vehicle while the vehicle controller performs the computing tasks.

A climate control device includes a radiant heater for radiating heat and a porous material attached to the radiant heater. The porous material desorbs a plurality of water molecules, in response to the porous material receiving heat from the radiant heater and raising a temperature of the water molecules in the porous material to a boiling temperature threshold. The porous material adsorbs the water molecules in response to the temperature of the water molecules falling below the boiling temperature threshold.

A heat pipe is provided for cooling an electronic component of a printed circuit board. The heat pipe includes a tube having an inner diameter surface defining a bore, with the tube having first and second ends along the bore. The heat pipe further includes a sorbent material coated onto the inner diameter surface of the tube, a first liquid contained within the bore, and a second liquid adsorbed by the sorbent material. The second liquid has a second boiling temperature that is higher than a first boiling temperature of the first liquid. The first liquid vaporizes into a first vapor, in response to the tube receiving heat from the electronic component and the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material and vaporizes into a second vapor in response to the second liquid reaching the second boiling temperature.

Systems, apparatuses, and methods are described that combine a sorbent containing a flame retardant with a substrate, which is capable of responding to temperature increases to prevent, suppress, delay the spread of, or otherwise mitigate a proximal thermal event. A flame retardant system has a flame retardant material that is incorporated into a matrical sorbent material, which is incorporated into a substrate. The matrical sorbent material is configured to release the flame retardant material upon exposure to an elevated temperature, e.g., a temperature that is greater than 300&#xb0; C. in one embodiment.

A system for determining a trigger amplitude indicating a precursor to a material fracture in a specimen under test includes a microphone converting acoustic emission emitted by the specimen under test into electrical signals. A load is exerted upon the specimen under test and the acoustic emission are emitted when the load causes the specimen under test to undergo deformation prior to the material fracture. A control module is in electrical communication with the microphone and executes instructions to monitor the electrical signals generated by the microphone and filter the electrical signals generated by the microphone. The control module converts the electrical signals generated by the microphone into individual frequency components based on a fast Fourier Transform (FFT). The individual frequency components each include a peak intensity. The control module determines the trigger amplitude based on the peak intensity of the individual frequency components of the FFT.

A heat dissipation device for an electronics cooling system having an electronic component includes a housing that defines a chamber. The device further includes a first liquid, which is contained within the chamber and has a first boiling temperature. The device further includes a sorbent material immersed within the first liquid. The device further includes a second liquid, which is adsorbed by the sorbent material and has a second boiling temperature that is above the first boiling temperature. The first liquid vaporizes into a first vapor, in response to the first liquid reaching the first boiling temperature. The second liquid is desorbed from the sorbent material, in response to the second liquid and the sorbent material reaching a desorption temperature that is below the second boiling temperature. The second liquid vaporizes into a second vapor, in response to the second liquid reaching the second boiling temperature.

Methods and systems for receiving, by a destination device at which a securement-monitoring application is operating, from a securement sensor device, a securement-condition communication indicating a condition of a securement remote to the destination device. Operations also include determining, by the destination device using the securement-monitoring application, an action to take responsive to the securement-condition communication, such as notifying a user of an undesired condition at the securement. The operations further include initiating the action determined.

Automated wireless securement-monitoring and feedback system

A system implemented at a user structure, to monitor a tracked object using a three-body arrangement including the user, a tracked object, and a controlling apparatus. The system has a data storage device including user-presence module code causing a processor to determine, based on wireless sensing, whether the user has entered a first space having a boundary external to the user structure, or has left the space. Object-presence module code causes the processor to determine, based on tracked-object-presence data, whether the tracked object is within a second space. And the storage device includes alert-module code to, in response to determining that, depending on the embodiment, (i) the user entered or exited the first space and (ii) the tracked object is or is not present within the second space, initiate provision of a system-user alert communication to indicate that the tracked object is not present within the second sensed space.

An electric-vehicle power management system including a processing hardware unit and multiple modules executable by the processing hardware unit. The modules include a calendar module configured to, by way of the processing hardware unit, obtain a user itinerary indicating multiple appointment locations to be visited by a user of an electric vehicle and associated times to visit the appointment locations. The modules also include a routing module configured to, by way of the processing hardware unit, determine optional routes connecting the appointment locations indicated by the itinerary, and a vehicle-energy module configured to, by way of the processing hardware unit, predict states of charge, or changes in state of charge, for the vehicle in connection with the optional routes, yielding state-of-charge predictions. The routing module determines selected routing based on the state-of-charge predictions from the vehicle-energy module. Analogous methods and computer-readable storage devices are also provided.
