Abstract: A device, system, and method for global maximum power point tracking comprises monitoring an output power of a DC power source while executing a maximum power point tracking algorithm and adjusting a maximum power point tracking command signal in response to the output power being less than a reference output power. The command signal is adjusted until the output power exceeds a previous output power by a reference amount. The command signal may be a voltage command signal, a current command signal, an impedance command signal, a duty ratio command signal, or the like.

Abstract: A system, method, and computer storage configured for determining period-ending positions of multiple parts movable by select actuation of corresponding active materials. The operations include receiving, from a work-source sensor, work-source input indicating a distance moved by the work source and a direction of the movement, and determining, based on the work-source input and a first and second status histories, corresponding to a first and a second part, respectively, first and second distances travelled by the parts, respectively. Operations also include calculating, based on the first and second distances determined and first and second period-starting positions, corresponding to the first and second parts, respectively, first and second period-ending positions for the first and second parts, respectively.

Abstract: An actuator system for use in selectively engaging an input to an output. The actuator system includes an input sub-system having an input component configured to connect to an input element which is in turn connected to a work source. The actuator system also includes an output sub-system being connectable to the input sub-system for receiving work from the work source via the input sub-system. The actuator system further includes an actuator sub-system having an active material and an actuating component. The actuator sub-system is configured so that the active material, when activated, causes the actuating component to move from a first state to a second state to disengage the input and output sub-systems.

Abstract: A portable structure for use in ice fishing. A two-piece structure that generally includes a lower shell and a separate removable hard cover shell that is installed onto the lower shell is provided. Further, the lower shell is formed as a hull, having a floor surrounded by exterior sidewalls to define an interior well within the lower shell. The cover unit is interfittingly received onto the walls of the sidewalls of the lower shell to complete the enclosure. The separability of the lower shell and the cover allow easy removal of the cover. When being transported, the cover of the shelter is removed, inverted and placed within the lower shell.

Abstract: A water softener particularly for use in a dishwasher. The water softener is located in the dishwasher water supply (238) between the primary supply valve and the wash chamber. The softener includes a resin container (207) with an ion exchange resin (290). Water supplied to the wash chamber optionally passes through the resin container (207). Regenerating brine is developed in a brine container (203). The brine container (203) is supplied manually with solid salt (270) and water diverted into the container from the main supply at an air break (201). In the regenerating cycle brine is delivered from the brine container (203) to the resin container (207) by a pump (206). The duty cycle of the pump (206) determines the degree of regeneration of the resin (290).

Abstract: A portable structure for use in ice fishing is disclosed. The present invention provides a two piece structure that generally includes a lower shell and a separate removable hard cover shell that is installed onto the lower shell. Further, the lower shell is formed as a hull, having a floor surrounded by exterior sidewalls to define an interior well within the lower shell. The cover unit is interfittingly received onto the walls of the sidewalls of the lower shell to complete the enclosure. The separability of the lower shell and the cover allow easy removal of the cover. When being transported, the cover of the shelter is removed, inverted and placed within the lower shell to reduce the exposure of the structure during transport and reduce the volume of space necessary for storing the shelter when not in use. The construction provides that when the two pieces are joined together a rigid lightweight structure is created that is capable of floating itself and its occupants in the event of an ice failure.
