Abstract: A programmable circuit board, preferably including: a rig, a reservoir, and working metal, wherein the rig preferably includes a set of unit cells cooperatively defined by a stack of substrates and a set of driver elements. A method for dynamically programming a circuit board, preferably including: receiving a circuit board design; determining a unit cell map; positioning working metal; optionally assembling a remainder of circuit board components; optionally testing the assembled PCB analog; and/or optionally updating the physical PCB analog configuration.

Abstract: This generally relates to one or more safety mechanisms of a rechargeable battery for light electric vehicles. The rechargeable battery may include a housing containing a battery management system and at least one battery cell, and a communication system communicatively coupled to the battery management system, where the communication system wirelessly communicates information received from the battery management system to a device external to the rechargeable battery. The rechargeable battery may include a housing formed of a first clamshell member and a second clamshell member. The rechargeable battery may include a first protrusion portion extending from an interior surface of the first clamshell member and a second protrusion portion extending from the interior surface of the second clamshell member toward the first protrusion portion such that the first and second protrusion portions physically contact one another when a force is applied to an external surface of the housing.

Abstract: A rechargeable battery kiosk can dynamically alter a charging rate of one or more rechargeable batteries housed within the rechargeable battery kiosk to increase a probability that the rechargeable battery kiosk has an ample supply of fully charged, or mostly fully charged, rechargeable batteries based on an anticipated usage data for the rechargeable battery kiosk.

Abstract: The present disclosure describes a system for dynamically determining an accurate location of a light electric vehicle. For example, if a light electric vehicle is within a predetermined distance of a location for which an accurate location determination is needed or required, a light electric vehicle management system may update the determined location of the light electric vehicle with a location correction factor that is based, at least in part, on a reference location provided by a stationary reference point.

Abstract: The present disclosure describes a system for determining an optimal gear ratio for a light electric vehicle. The optimal gear ratio may be based on an anticipated or current route of an individual riding the light electric vehicle, riding habits of the individual and/or on maintenance status information associated with the light electric vehicle. When the optimal gear ratio is determined, the system provides an indication of the optimal gear ratio to the light electric vehicle.

Abstract: The present disclosure describes a system for detecting, identifying and addressing a maintenance event for light electric vehicles. The maintenance event may be detected based on rider profile information, riding parameter information and light electric vehicle information. If a maintenance event is detected, a light electric vehicle management system may determine an action that addresses the maintenance event and provide instructions regarding the action to the light electric vehicle and/or one or more individuals that are trained or otherwise certified to address the maintenance event.

Abstract: The present disclosure describes how to determine a range offering for a light electric vehicle. The range offering may be based on riding habits of an individual that provides a reservation or use request to ride the light electric vehicle and on information associated with the light electric vehicle. The range offering may be used to determine whether a light electric vehicle can or should be used by an individual to transport the individual from an origin to a destination.

Abstract: A method for reducing the formation of deposits on the inner walls of a tubular heat exchanger through which a petroleum-based liquid is flowing comprises applying one of fluid pressure pulsations to the liquid flowing through the tubes of the exchanger and vibration to the heat exchanger to effect a reduction of the viscous boundary layer adjacent the inner walls of the tubular heat exchange surfaces. Reduction of the viscous boundary layer at the tube walls not only reduces the incidence of fouling with its consequential beneficial effect on equipment life but it also has the desirable effect of promoting heat transfer from the tube wall to the liquid in the tubes. Fouling and corrosion are further reduced by the use of a coating on the inner wall surfaces of the exchanger tubes.
