Abstract: A power assembly module provides multiple interfaces for accessing a battery. A power input of the power assembly module can receive power from a variety of external sources. Photovoltaic panels, car batteries, or any other suitable DC power source can be used to charge the battery within the power assembly module. A switch provided on a housing of the module allows for activation or deactivation of power delivery from the battery, at outputs of the power assembly module. In some embodiments, the power assembly module includes a single power output that provides power from the battery using a cabled connector. Additionally, the power assembly module includes a power distribution element that provides power from a standard plug outlet for powering certain appliances that receive power using a standardized electric plug terminal.

Abstract: A device includes a signaling means and a motion sensor, and logic for activating or controlling the signaling means in response to a sensed motion according to an embedded logic. The device may be used as a toy, and may be shaped like a play ball or as a handheld unit. It may be powered from a battery, either chargeable from an AC power source directly or contactless by using induction or by converting electrical energy from harvested kinetic energy. The embedded logic may activate or control the signaling means, predictably or randomly, in response to sensed acceleration magnitude or direction, such as sensing the crossing of a preset threshold or sensing the peak value. The visual means may be a numeric display for displaying a value associated with the count of the number of times the threshold has been exceeded or the peak magnitude of the acceleration sensed.

Abstract: Disclosed herein are systems and methods for energy management. A system (e.g., a vehicle) includes energy storage units that include a supercapacitor and an electrochemical battery. The system includes a communication interface that receives an indication of a requested process to be powered using at least a subset of the plurality of energy storage units. The system includes an energy controller that tracks historical power draw from the energy storage units over time in power tracking data, and that identifies a power draw for the requested process based on the power tracking data. The energy controller switches between a first configuration and a second configuration for the requested process based on the identified power draw for the requested process. The first configuration draws power from the electrochemical battery and disconnecting from the supercapacitor, while the second configuration draws power from the supercapacitor and disconnecting from the electrochemical battery.

Abstract: Disclosed herein are systems and methods for energy management. A system, such as a vehicle, includes a plurality of energy storage units that include a supercapacitor and an electrochemical battery. The system includes an energy controller that identifies a safety threshold associated with at least a subset of the energy storage units. The energy controller tracks historical power draw from the plurality of energy storage units over time in power tracking data, and identifies a power draw based on the power tracking data. The energy controller switches between a first configuration and a second configuration based on the identified power draw crossing the safety threshold. The first configuration is configured for drawing power from the electrochemical battery and disconnecting from the supercapacitor, while wherein the second configuration is configured for drawing power from the supercapacitor and disconnecting from the electrochemical battery.
