Abstract: A system for directing and compelling cleaning of the keys of the keyboard by a user carrying out a wipe-down process by detecting the keys as they are pressed during wipe-down, and analyzing the key depression data to determine the thoroughness and completeness of the cleaning cycle.

Abstract: A computer keyboard is designed to accommodate a variety of security features that may be installed in the keyboard during manufacturing, whereby various combinations of devices that impart selected security features or other functions may be assembled. The keyboard assembly includes a base extension for accommodating the security devices, and a number of interchangeable modular tops supporting various discreet input technologies. This modular design is tooled to accommodate different combinations of technologies, such as biometric fingerprint readers, NFC-RFID receivers, auto locking sonar, game cartridges, and connector-supporting modules. Each interchangeable modular top can hold independent modular technology that can be used to construct an integrated device that meets the customer requirements without any substantial modification of the keyboard base or extension.

Abstract: A terminal for a computer system includes a keyboard incorporating modules for performing two factor authentication (TFA) for log-on of a user. TFA preferably combines a fingerprint scan with the proximity of a previously enrolled Bluetooth device that typically accompanies the user, such as a wireless phone or headset. The keyboard also includes an ultrasonic proximity detector aimed to detect the presence of the user at the keyboard and to terminate log-on when the user leaves the keyboard. The keyboard processor may be used as an encryption engine to encode all keystroke data and authentication/log-on transactions with the computer system.

Abstract: A computer keyboard supports an ultrasonic user presence detector (UPD) that is rotatable and supported on the upper surface of the keyboard, adjacent to the uppermost row of keys and located adjacent to one corner of the keyboard. The UPD is aimed at an elevation of 20°, and rotates to sweep through an angle of approximately +35° to ?20° to be selectively directed toward the most-likely position of an individual using the keyboard, so that the proximity detection error rate is very low. In one embodiment the UPD housing is rotatably supported on a modular interchangeable top secured to the keyboard at the upper margin thereof adjacent to the uppermost row of keys.

Abstract: A modular identity authentication apparatus for a computer system includes at least two different authentication technologies, such as biometric fingerprint readers, NFC-RFID receivers, and BYOD sensors. Each modular apparatus provides multiple authentication sensors that are connected through a single port at a computer terminal location. System software permits terminal use when all module devices are authenticated, and shuts down the terminal whenever the module is disconnected.

Abstract: A method and apparatus disinfecting a computer keyboard includes a metal ion treatment applied to the computer keyboard and other user input devices. A further measure taken is the installation of a shutoff mechanism in the link connecting the computer keyboard to the computer system to open the data connections between the keyboard and host system. Another measure is the periodic and reiterated wipedown of the keyboard and ancillary input devices with an antiseptic wipe. The shutoff mechanism is turned off before the wipedown procedure is carried out, to prevent any incidental keyboard entries made during the wipedown process from being transmitted to the host system.

Abstract: Dairy whey, a waste product of cheese production, is fermented with an organism to produce a whey product containing an emulsifier. Fermentation is carried out by forming a fermentation broth of whey or whey and oil, and optionally yeast extract and then fermenting the broth with Candida lipolytica. The resultant fermented whey product is used as an emulsifying agent in the food industry.

Abstract: A vegetable oil and mineral salts broth is fermented with an organism to produce a vegetable oil product containing an emulsifier. Fermentation is carried out by forming a fermentation broth of vegetable oil and mineral salts, and optionally yeast extract and then fermenting the broth with Candia Lipolytica. The resultant fermented vegetable oil product is used as an emulsifying agent in the food industry.

Abstract: Diary whey, a waste product of cheese production, is fermented with Xanthomonas campestris ATTCC 31923 to produce a fermented whey product containing a thickening polymer. The fermented whey product can be used as a thickening agent by the food industry. Yeast extract may be added to the whey prior to fermentation. Xanthomonas campestris ATCC 31923 is a novel microorganism having the ability to grow on lactose as the sole source of carbon.

Abstract: Dairy whey, a waste product of cheese production, is fermented to produce a thickening agent for use in the food industry by forming a fermentation broth containing whey and sucrose, and fermenting the broth with Leuconostoc mesenteroides ATCC 14935. The fermentation broth can optionally contain a water-soluble phosphate as a pH buffer and yeast extract.

Abstract: Dairy whey, a waste product of chesse production, is fermented with an organism to produce a whey product containing a thickening polymer that serves as a thickening agent. Fermentation is carried out by forming a fermentation broth of whey and glucose, and optionally a water soluble phosphate and/or yeast extract and then fermenting the broth with Xanthomonas campestris ATCC 31922. The resultant fermented whey product is used as a thickening agent in the food industry.
