Abstract: Provided herein are energy storage devices. In some cases, the energy storage devices are capable of being transported on a vehicle and storing a large amount of energy. An energy storage device is provided comprising at least one liquid metal electrode, an energy storage capacity of at least about 1 MWh and a response time less than or equal to about 100 milliseconds (ms).

Abstract: A portable keyboard enables full QWERTY touch typing with both hands or full QWERTY typing with one hand without external support. The keyboard includes a number of keypads that are selectively positionable to configure the keyboard in different keyboard configurations for use.

Abstract: Sign holders are provided for displaying sign inserts. The sign holders are capable of being reused, whereby several different signs can be removably affixed to the sign holders for displaying signs at multiple events. Signage systems are also provided, comprising a plurality of sign holders and an optional container for storing and transporting the same.

Abstract: A portable keyboard enables touch typing with both hands without external support. The keyboard includes a first array of keys and a second array of keys on opposite sides of the keyboard. The keyboard is held between the hands and is supported against the palm of one hand for touch typing with both hands.

Abstract: A method of alleviating the sound masking effects of wind noise on a cyclist wearing a safety helmet comprising the following steps: designing an ear cover shield having a generally smooth exterior side; positioning the cover shield adjacent to but generally spaced from an ear of the cyclist so that wind is generally deflected from the ear so that the noise of air rushing over the ear is substantially reduced, and the cyclist is better able to hear proximate sound especially that sound generated from directions which he cannot readily see; and, positioning and holding the cover shield adjacent to the ear most preferably by adjustably attaching it to a strap on the helmet. When wearing a cover shield, even in a strong wind, a cyclist is able to hear a vehicle approaching from the rear so that he can accordingly move close to the side of a roadway and ensure that his cycle moves in a straight, unswerving path.

Abstract: A method of forming arrays of electrochemical cells, and improved arrays of cells formed thereby, in which layers of electrically conductive material (16), layers of cathode material (12) and layers of anode material (10) are applied to first and second flexible, electrically insulating surfaces (18) in respective predetermined patterns such that the areas of applied anode and cathode material corresponding to anodes and cathodes of individual cells on each of said surfaces are formed in electrical connection with or isolation from one another by said pattern of conductive material as required in the finished battery; and said surfaces are assembled together such that respective areas of anode and cathode material on said first surface are aligned with corresponding areas of cathode and anode material of said second surface, electrolyte material being disposed between said first and second surfaces such that a plurality of electrically interconnected cells are formed thereby.

Abstract: A substantially farinaceous, fiber-containing batter to produce a battered and fried food having reduced lipid retention and increased moisture content after frying. The preferred fibrous additive for this purpose is powdered cellulose; however, various dietary fibers such as oat fiber, soy fiber, pea fiber, or sugar beet fiber, to name only a few, may be used to achieve the same purpose. More specifically, the fibrous additive is preferably present in the batter in an amount of about 0.3-3.0% by weight of the batter having an average fiber length of from about 50-500 microns. The addition of fiber to a batter used for frying will allow food producers to provide a healthier fried food item which will be more appealing to a health conscious consumer. Moreover, the fiber additive can also enhance the appearance of the fried food by providing a golden yellow color after frying, rather than a non-uniform brown color containing brown and black batter particles.

Abstract: A low calorie ice pop formulation containing powdered cellulose having an average particle size of less than about 20 microns.
