Various features of the assembly are described. Also described are methods of manufacturing the same, some of which are directed to methods of pre-fabrication, mass manufacture and transportability. Also described are methods of installing the same, some of which are directed to methods of laying out in grid patterns for large-scale projects.

Abstract: This application discloses a method to use sensors for games of skill relating to physical exercise. The method may employ the use of sensors that can collect data, including location using GPS, sense barometric pressure, steps walked, blood oxygen levels, navigational directions, gyroscopic movement, heart rate, and many other data types. Players may challenge other players to competitions wherein the players make a challenge wherein a winning player is rewarded a wager. Data collected by the sensors may be used for metrics to determine the winning player.

Abstract: An energy storage system is provided and comprises a battery management unit; a controller configured to start an idle condition timer, measure a voltage of a battery cell of a battery connected to the battery management unit while the battery is idle, after the idle condition timer has expired, start a steady condition timer, measure the voltage of the battery cell while the battery is on, after the steady condition timer has expired, calculate a total resistance of the battery cell, and calculate an open circuit voltage of the battery cell using the total resistance.

Abstract: A portable energy system is provided and includes a controller configured to control periodic polling to determine when a load is attached or actively connected to the portable energy system, such that when the load is attached to the portable energy system, the controller energizes the portable energy system for supplying power to the load, and when the load is not attached or not actively connected to the portable energy system, the controller deenergizes the portable energy system output for not supplying power to the load.

Abstract: A storage system configured for use with an energy management system is provided herein and comprises a battery, a battery management unit coupled to the battery and a power converter comprising plurality of microinverters operably coupled to the battery and the battery management unit, each microinverter of the plurality of microinverters configured to calculate an estimate of state-of-charge of the battery and periodically communicate a calculated estimate of state-of-charge to the other microinverters, such that each microinverter of the plurality of microinverters calculates an average state-of-charge of the battery and communicates the calculated average state-of-charge to the battery management unit for controlling charging/discharging of the battery.

Abstract: The invention is a universal mounting system allowing a wide variety of accessories to be used interchangeably among one or more mounts secured to convenient surfaces or structures, such as the gunnel of a boat. The universal mount system includes a mount having barrel configured to receive the insert member of an accessory. A locking mechanism on the mount engages the insert automatically and interlocking splines on the insert member and along the barrel of the mount secure the insert at a desired rotational orientation.

Abstract: The invention is an adjustable rod holder comprising a tubular holster mounted to an arm and a base, wherein the arm is secured to the base by a rotating joint that is secured in a first angular position by a locking member that moves radially with respect to an axle of the rotating joint. The rotating joint can be releasably secured at a plurality of indexed angular positions by the locking member fitting within a plurality of recesses spaced radially about an axle of the rotating joint. Preferably, the arm of the rod holder has a sufficient length to allow the rod holder to store the rod in a vertical position without interference from the gunnel or other mounting surface. In one embodiment, the rod holder has a pivoting stabilizer that engages the reel of a rod placed in the holder to secure and stabilize the system.
