Title: Germicidal toothbrush and toothbrush holder
Inventor: RIDDELL ROBERT H
IPC: A46B17/06
Filed: 2004-07-12
Abstract: This patent describes a special toothbrush made with bristles of optical fibers that conducts ultra violet germicidal light by total internal reflection. The germicidal light must be directed from a low angle, usually greater than 43 degrees from the normal, so that it will result in total internal reflection of the light so all the bristles are sterilized from top to bottom. The germicidal light can come from an ultra violet germicidal lamp---or--groups of ultra violet germicidal light emitting diodes. (LED's)----or-groups of ultra violet germicidal micro lasers. There is a timer and off/on switch. The time should be about 20 minutes because the bristles must dry out before the germicidal effect will take place. The on/off switch is used to turn the light on after the door is closed and sealed to prevent light from escaping. The light will not turn on unless the door is closed and sealed.  This is a safety feature that is necessary because germicidal light is detrimental to the eyes. Because the outer bristles of a toothbrush tend to bend out after considerable use, it is best to have the light come from both sides to accommodate this bending of the bristles. Opening at the bottom to allow water to escape because the toothbrush will be wet after use.

Title: Nucleotide sequence coding for a mannitol 2-dehydrogenase and method for the production of d-mannitol
Inventor: WALTER MARTIN
IPC: C12N9/04
Filed: 2003-05-06
Abstract: The invention relates to a nucleotide sequence coding for the mannitol 2-dehydrogenase and a method for producing D-mannitol. Previously known biocatalytic methods for producing D-mannitol yield only small production rates due to the small number of specific activities of mannitol 2-dehydrogenases used for transforming D-fructose into D-mannitol. D-mannitol production can be improved by supplying a nucleotide sequence which codes for a mannitol 2-dehydrogenase having a higher specific activity. Mannitol production can be increased in a particular manner by creating a regeneration system for reduction equivalents by introducing and/or strengthening a formiate dehydrogenase in a microorganism.

Title: Tool for in vitro-in vivo correlation
Inventor: FARRELL COLIN B
IPC: G16B40/10
Filed: 2003-08-13
Abstract: A biological modeling system and method for enhanced computer-aided analysis of biological response data provides information synthesized from immediate and extended release in vivo data and in vitro data. An executable model of a biological system is developed from information and structures based on the data. In a preferred embodiment, a two stage approach to modeling is used in the development of an IVIVC. The first stage of the procedure is deconvolution, where the percentage of drug absorbed is determined. In the second stage, the in vivo percentage absorbed data is correlated to the in vitro fraction or percentage dissolved data. This correlation then represent s a point-to-point relationship between the in vitro dissolution and the in vi vo input rate of the drug from the dosage form. In such a correlation, the in vitro dissolution and in vivo absorption profiles are either directly superimposable or may be made to be superimposable by the use of a scaling factor. Prior to the deconvolution stage, a unit impulse response function c an be determined from immediate-release concentration-time data. This impulse response function is used in the deconvolution process to determine the in vivo percent absorbed for the extended release formulations. A nonlinear IVI VC model is developed that can incorporate time-scaling and time-shifting into the model if needed. After the two-stage modeling is completed, the predictability of the developed IVIVC model is evaluated by both internal an d external validation.

Title: Method and apparatus for soliciting connectivity from wireless data networks
Inventor: ZHAO WEN
IPC: H04W88/00
Filed: 2005-07-15
Abstract: According to the embodiments of the techniques of this application, a wireless data device or other data node sends solicitation messages periodically to a wireless gateway, such as a PDSN, when there is no data traffic between the wireless data device and a wireless data network. Each solicitation message resets the simple IP inactivity timer on the wireless gateway. When multiple wireless data devices send solicitation messages, the interval between subsequent transmissions of solicitation messages is randomised to reduce the probability of collision with the solicitations from other devices on the same wireless link. The solicitation timer, for instance, may be based on the simple IP inactivity timer setting on the wireless network, and the number of wireless data devices that the wireless data network serves. Expiration of the solicitation timer at the wireless data device or other data node causes the next solicitation message to be sent from or on behalf of the wireless data device.
