Abstract: A modular, weight-shift controlled watercraft device is disclosed which includes: a modular board removably attachable to a power system. The power system includes a modular power supply system, and a modular propulsion system. The power supply system includes a housing including a battery. The propulsion system includes a modular strut, a modular propulsion pod, and a modular hydrofoil. In one embodiment, the power supply system is removably and mechanically attachable directly to the propulsion system.

Abstract: A liner for a child safety seat designed with horizontal slits and fasteners and an elastic gathering at the upper portion of the car seat liner to permit the car seat liner to be draped over and secured to the car seat using a five-point harness system. The overlapping portions of the car seat liner prevent a car seat from becoming soiled when used by an infant or child.

Abstract: A shelf system includes at least one modular shelf assembly including at least one shelf unit, a plurality of support posts, an adjustable foot, covers, and anchors. The at least one shelf unit, plurality of support posts, adjustable foot, covers, and anchors are, in combination, adapted to create the modular shelf assembly. Each shelf unit is adapted to receive the plurality of support posts, including one support post generally located adjacent a rear side of the shelf unit about half-way between a first and a second end of the shelf unit.

Abstract: A first shock isolator is provided that includes an axial compression element, a first disc spring, a disc spring system, and an annular stand-off. The first disc spring has a non-linear load-deflection response. The disc spring system is configured to be deflected by the first disc spring and has a linear load-deflection response. A second shock isolator is provided that includes an axial compression element, first and second disc springs and corresponding first and second annular stand-offs. The first and second disc springs have non-linear load-deflection responses. The first and second annular stand-offs hold the first disc and second disc springs in a spaced apart parallel configuration. The second disc spring is configured to be deflected by the first disc spring. The first and second shock isolators exhibit first and second combined load-deflection curves that include a constant load region.

Abstract: A personal watercraft is disclosed including a flotation portion, a strut extending from the flotation portion, and a motor pod is disposed along the strut with an electric motor operably coupled to a driveshaft. A hydrojet unit is removably attached to the motor pod and includes an inlet portion removably attached to the motor pod and a substantially cylindrical housing. The inlet portion includes a substantially conical motor interface with a shaft through-hole for receiving the driveshaft therein, one or more fins extending outwardly from the conical motor interface, and at least one ring encircling the conical motor interface and connecting to each of the one or more fins for inhibiting objects from passing through the inlet region. The housing defines a fluid flow path to an outlet portion. The hydrojet unit includes an impeller coupled to the driveshaft and a stator disposed within the housing.

Abstract: The innovation relates to a pool covering system that is usable as a flooring surface. The pool covering system includes brackets that support beams spanning the pool opening. The beams provide structural support to cross members and flooring placed on top of the beams. The pool covering system does not require significant drainage of the pool and does not damage the pool structure during installation and use.

Abstract: A battery plate having a substrate with opposing surfaces and one or more nonplanar structures and one or more active materials disposed on at least one of the opposing surfaces; wherein the battery plate includes one or more of: i) one or more projections disposed within but do not extend beyond the active material; ii) one or more projections which project beyond the active material and substantially free of the active material or dust formed from the active material; and/or iii) a frame about the periphery of the substrate which projects beyond the active material and is substantially free of the active material or dust formed from the active material; and wherein the battery plate is adapted to form part of one or more electrochemical cells in a battery assembly.

Abstract: An artists' brush storage and protection device includes a storage unit having a plurality of storage compartments, each of the storage compartments including a cover with a paint well below the cover, the paint well defined in part by upstanding walls, an exterior one of the upstanding walls defining a recess with a resilient sealing member disposed therein. Each of the covers may be opened permitting access to the paint well or closed against the upstanding walls of the paint well and the sealing member. The storage unit may further include drawer slides and a palette slidable on the drawer slides relative to the storage unit to reveal or conceal the palette. When bristles of a paint brush are placed in the paint well, its handle rests upon the resilient sealing member which compresses around the handle when the cover is closed to provide a substantially air-tight seal.

Abstract: Systems, methods and devices are provided for real-time tracking a location an asset (e.g., package) that is in transit (rail, air, truck, etc.) and real-time monitoring of environmental conditions that the asset is subjected to during transit such as temperature, light exposure, barometric pressure, and other conditions.

Abstract: A combination for illuminating the interior of a building comprises a fixture and a retrofit kit. The fixture has a base attached to a building ceiling, the fixture having a first tombstone, and a second tombstone. The first and second tombstones are configured to receive between them a fluorescent light tube. The retrofit kit is connected to the base. The retrofit kit includes a light panel, the light panel having a first side facing the fixture and an opposite second side. The light panel resides between the first tombstone and the second tombstone, and the fixture resides above the light panel. The combination is devoid of a fluorescent light tube. The base and the light panel define between them a raceway. A light emitting diode is disposed on the second side of the light panel.
