Title: Method of preparing alpha-1 proteinase inhibitor
Inventor: LEBING WYTOLD
IPC: C07K1/18
Filed: 2000-12-14
Abstract: Purification of .alpha.-1 proteinase inhibitor (.alpha.-1 PI) from aqueous solutions, such as human plasma, is accomplished by precipitation of contaminating proteins from the aqueous solution, followed by dilution of the solution to adjust its conductivity, and passing of the solution through an anion exchange resin. The conductivity of the solution is adjusted so that the .alpha.-1 PI binds to the anion exchange resin, while other contaminating proteins and solvent pass though the resin. Further purification may be accomplished by cation chromatography, which takes advantage of the fact that .alpha.-1 PI does not bind to the cation column under certain conditions. Some embodiments of the invention also include virus removal and/or inactivation by methods such as nanofiltration and such as contact with a non-ionic detergent.  The methods of the present invention result in greater yield, purity, and pathogenic clearance of plasma fractions than known methods.

Title: A system for encryption of wireless transmissions from personal palm computers to world wide web terminals
Inventor: MULLEN SHAWN PATRICK
IPC: H04L29/06
Filed: 2002-03-04
Abstract: Encryption is provided in wireless personal palm type computer devices for Internet transmitted documents despite the limited data processing and memory functions in such devices. The palm type device initially encrypts only a portion of a text document which is then wirelessly transmitted to the server computer which normally functions as the Web server, i.e. the server through which Web computer terminals are wired or connected into the Web. This Web server then further encrypts the received text document and then further transmits this further encrypted document to a terminal in said network.  Preferably, the further encryption in the server involves two steps:  decrypting the lower level encryption (necessitated by the limited CPU and memory resources in the palm device) to restore the text document at the server before the server may then re-encrypt the whole document using a higher level conventional 128 bit Web encryption protocols such as SSL.

Title: A wearable and portable keyboard operable with only one hand
Inventor: EXCIR STEVEN
IPC: G06F3/0354
Filed: 2004-05-06
Abstract: This wearable and portable keyboard is an one-hand operable and vertically modified with respect to a conventional keyboard and attached onto a person's thigh (on the clothing or under the clothing) and is used to enter text and data into the electronic devices such as cell phones, Personal Digital Assistants (PDAs), or portable hand-held computers via a cable attachment or a secured wireless means.   The wearable, portable keyboard is implemented as a vertically modified keyboard which is strapped onto a person's thigh as shown in FIG.2. This keyboard is an accessory for entering teat and data into a cell phone, a PDA (Personal Digital Assistant) or a portable computer. This innovative keyboard is operated by one hand. Nonetheless, it has all the standard keys of a conventional keyboard. It is also designed with our finger sizes in mind.  Therefore, instead of operating a PDA or cell phone with our thumbs, when we are moving around, on a bus, on a train, or sitting on a bench, we use our PDAs or cell phones to monitor what we punch on the keyboard attached to other thigh with our fret hand. Furthermore, these keyboards may be worn under the clothing or on the clothing. They could be made transparent made of durable nylons or polymers, or they can be made of other waterproof light fabrics. A  cable may be used to send the stream of text or data to a cell phone or a PDA via USB or serial port (e.g. RS-232). More conveniently, the keyboard can send data to the devices wirelessly using already available technologies such as the Blue-Tooth or a radio frequency (RF) transceiver. But attention must be made to the security of the data on the later case, for example the data must be coded randomly for each individual keyboard made which may be hard coded in the keyboard circuitry or can be changed as frequent as need by the owners of the keyboards.

IPC: B21D5/04
Filed: 2004-05-26
Abstract: The tool kit comprises a set of angle gauges for measuring angles in a workpiece being formed in a sheet metal bender, and printed math tips and charts related to the angle gauges. Each angle gauge has an elongated shape with juxtaposed longitudinal base surface and longitudinal angled surface; and an indicia thereon indicating a nominal angle. The angled surface makes a true angle with a transverse projection of the base surface. This true angle corresponds to the sum of the nominal angle on the indicia plus a supplement angle. The nominal angles on the angle gauges in the set are different from each other, and the supplement angle is common to all angle gauges in the set. The supplement angle corresponds to the slope of the nose bar in the sheet metal bender. The entire set can be used an a same bender to measure different angles.
