摘要:
The present invention provides a hub cover for a wheel hub on a vehicle used for agriculture and a stud extension piece used to operatively affix the hub cover to the wheel hub. In a preferred embodiment, the hub cover comprises a polyethylene convex dome that is affixed to the wheel hub of the vehicle using a stud extension piece that couples the hub cover to an exposed wheel hub. The use of the hub cover minimizes crop damage caused by the exposed hubs of the vehicle in crop fields.

A method of activating a micro-cell in which the micro-cell includes a first compartment, a second compartment, a fluid in the first compartment, an element in the second compartment and a porous barrier separating the first compartment from the second compartment. The porous barrier, in a first state, is operable to prevent the fluid from entering the second compartment whereas the porous barrier, in a second state, is operable, in response to an event, to allow the fluid to enter the second compartment and interact with the element in the second compartment so as to generate an activation signal.

A reserve battery having a prolonged shelf life that may be used in a wide variety of consumer related and non consumer related electrical devices. The reserve battery includes an outer enclosure, an internal breaking element extending directly from an inner surface of the outer enclosure and a breakable barrier positioned within the outer enclosure. At least one reservoir and at least one chamber are defined by the breakable barrier and the outer enclosure. An electrolyte material is contained within the reservoir and a plurality of electrodes are contained within the chamber. The plurality of electrodes receive the electrolyte material to activate the battery when manual pressure is applied to the internal breaking element to move the internal breaking element inwardly thus breaking the breakable barrier to allow passage of the electrolyte from within the reservoir to saturate the separator within the chamber.

A fluidic device includes a porous substrate, a wetting region extending through a first portion of the porous substrate from a first side of the substrate, in which the wetting region is permeable to fluid transport, and a non-wetting region extending through a second portion of the porous substrate from a second side of the substrate, in which the non-wetting region is operable to switch between a first state impermeable to fluid transport and a second state permeable to fluid transport.

An electrochemical cell includes a first cell, a second cell and a barrier isolating a fluid in the first cell from the second cell in which the barrier, in response to an activation signal, changes to a second state to allow the fluid to pass into the second cell and activate the electrochemical cell.

A portable battery booster for providing a compact, light, and energy efficient battery to jump start a vehicle. The portable battery booster generally includes a housing, a battery means adapted to be received by the housing, a pair of cable means, each of the cable means having a proximal end and a distal end, the proximal end electrically connected to the battery means and the distal end detachably connected to a discharged battery of the vehicle. The battery is generally comprised of one or more batteries having the type of primary lithium-metal, rechargeable lithium-ion, and/or lithium-polymer and more specifically preferably comprised of lithium iron phosphate for fast charging, small size, and high performance. The battery may also be connected to one or more supercapacitors, an internal CPU, DC/DC converter, etc. to increase performance. The cable means includes jaws that detachably connect to the housing in a flush and sleek manner.
