    摘要: An electrochemical cell or battery uses iron gall ink as an electrolyte. In some examples, mold, bacteria, or yeast are allowed to grow on the electrolyte. The ink is made by combining tannic or gallic acid from a material such as dehydrated tea with a metal or transition metal sulfate, such as iron sulfate, potassium sulfate, or manganese sulfate. Urea, a metal or transition metal salt, and glycerin can also be added to the electrolyte to assist in the ion-producing reaction. One example includes electrodes made from iron and graphite, and an electrolyte of iron-gall or iron-tannate ink. Another example uses a manganese based ink. Aluminum, potassium, or sodium tannate ink, urea, and graphite can be used to make a metal-air cell, in which the cell is open to the air. The ink can be used as a charge transport in a redox-flow electrochemical cell. Yet another example utilizes Bauxite residue, a waste product of aluminum manufacture. The Bauxite is used to form an ink and used in cells similar to those described above.

    摘要: A document encryption and decryption system and method for selectively encrypting and decrypting files and attachments, electronic mail, text messages, and any other items to protect or secure its contents by helping to prevent unauthorized individuals from viewing data in human-perceivable or readable form. The encryption and decryption system includes remote authentication to verify user credentials stored on a remote database hosted by a web server. The encryption system further includes remote deletion to automatically delete at least encrypted items stored on the user's computer, handheld or portable device, smartphone, tablet, and any other computer of any kind when enabled and logged onto a network. The encryption and decryption system includes selectively decrypting items by retrieving a decryption key and decrypting the item, and/or typing a decryption key if the item cannot be decrypted with the key, and/or sending an invitation to a recipient using the web server.

    摘要: A biopsy device includes a probe and holster that may be coupled together. The probe includes a cannula with a transverse opening and a cutter within the cannula. The holster includes a mechanism that is operable to rotate and translate the cutter within the cannula. In one example, the holster also includes a user interface having buttons and indicators. The indicators may indicate, e.g., the longitudinal position of the cutter within the cannula and an error condition. The buttons may be operable to, e.g., selectively and incrementally adjust the longitudinal position of the cutter within the cannula, initiate a sampling cycle, initiate a clear probe cycle, and initiate a lateral vacuum cycle. The user interface may also include a trigger operable to cock and fire the cannula into tissue. The user interface may be provided as one or more membranes on one or more sidewalls of the holster.

    摘要: An improved dry disc brake has its housing positioned radially inwardly of its rotating member. In this way, the interface between the pads and the rotor is sealed from the environment. Further, there are two braking surfaces on the rotating member at opposed ends of the housing. Since the braking heat is spread across two surfaces, the system is better able to take heat away from the braking operation. The use of external facing fins adds even more capacity to take heat away.
