Abstract: An optical absorption calorimeter performs absorbance measurements at low cryogenic temperatures, such as above 0K to 5K (e.g. near liquid helium temperature), using high-resolution thermometry with SQUID readout to probe optical absorption to better than 1 ppb. This improved sensitivity yields improved performance in calorimetric absorption spectroscopy by lowering the required excitation power, improving the spectral resolution, and opening up the full spectrum, from near-IR to near-UV and beyond for analysis.

Abstract: An oral care implement includes a handle and a head connected to the handle. A tissue cleanser is positioned on the head and has a textured surface and a plurality of apertures extending therethough. Each of a plurality of tissue cleaning elements extends through one of the apertures and extends outwardly from the head.

Abstract: This invention relates to S-MNTX, methods of producing S-MNTX, pharmaceutical preparations comprising S-MNTX and methods for their use.

Abstract: An oral care implement or toothbrush 100 includes a head 104, a tooth cleaning element region 116 and a tissue cleaning element region 114. The tissue cleaning element region 114 includes a plurality of flexible, angled projections 120. The projections 120 are configured to flex from an at-rest position to a substantially flat position when the tissue cleaning element region 114 is in contact with the tongue and is pushed into the mouth. The projections 120 are also configured to flex to a substantially upright position when the tissue cleaning element region 114 is in contact with the tongue and is pulled out of the mouth. This arrangement aids in preventing debris from being pushed into the mouth and in removing debris from the mouth and tongue. The flexible projections 120 may be used in conjunction with rigid projections 122 having a generally vertical configuration to aid in removing debris from the mouth and in engaging the cheek to improve saliva production during brushing.

Abstract: Field devices or other devices within a process control system are provided with both hardwired and wireless communication ports to enable communications to be performed within the process control system using one or both of hardwired and wireless communications. In particular, a field device for use in a process control system within a process control environment includes a microprocessor-based communication unit adapted to generate or receive communication signals, a first communication port adapted to be connected to a hardwired communication link for providing communications to or from the communication unit via the hardwired communication link and a second communication port adapted to be connected to a wireless transceiver to provide wireless communications to or from the communication unit via the wireless transceiver.

Abstract: A fluid dispensing oral care implement with fluid delivery system. The implement includes a storage member containing a fluid. A channel formed of one or more wicking or capillary members extends through at least a portion of the oral care implement to deliver fluid(s) through one or more fluid outlets via capillary action. In one embodiment, the fluid outlet is comprised of a wicking or capillary material and is disposed in the head of the implement. In some embodiments, the implement may include a valve and a specially configured storage cap. A variety of fluids can be administered for therapeutic, hygienic, and/or other benefits, such as fresh breath, tooth whitening, tooth sensitivity, plaque and/or tartar control, or producing sensations of heat, cool, or tingling.

Abstract: A fluid delivery system usable in an oral care implement and a reservoir containing a flowable substance. A capillary channel formed of one or more wicking or capillary members extends through at least a portion of the oral care implement to deliver flowable substance(s) through one or more outlets via capillary action. In one embodiment, the rate of fluid flow through the capillary channel is different in at least a first flow section than in a second flow section. In another embodiment, the rate of flow between flow sections of the wicking member is different than in at least one of the flow sections. A variety of flowable substances can be administered for therapeutic, hygienic, and/or other benefits, such as fresh breath, tooth whitening, tooth sensitivity, plaque and/or tartar control, or producing sensations of heat, cool, or tingling.
