An apparatus for cleaning the touch or display touch or display surface of an electronic device such as a cell phone or computer tablet comprising a wiper coupled to cleaner bar. The cleaner bar moves longitudinally and/or laterally across the electronic device with the wiper in contact with the touch or display surface. The wiper comprises both a moist pad and a dry pad. The moist pad is fluidly communicated to a reservoir defined within the cleaner bar. On its “cleaning stroke”, cleaning fluid is released into the moist pad and then deposited onto the touch or display surface. The cleaner bar moves longitudinally across the touch or display surface by manual or motorized means. The cleaner bar may also be in communication with the electronic device to detect when a task has been completed on the electronic device. After detection, the cleaner bar automatically traverses the touch or display surface, thereby cleaning it after every use.

A dental bracket having a non-adhering, moldable base, wherein the moldable base is conformed to the surface of the tooth to which it is to be adhered. A very thin layer of dental adhesive interposed between the moldable base and the tooth (by coating of any or both of the tooth and moldable base--preferably the tooth) effects full adherence of the bracket to the tooth. The base material is fully cured by normal curing methods such as by UV or other wavelength light activation. Use of a non-tacky, bondable plastic membrane (or coating or use of a thin inert interposition material which is non-tacky and bondable) bonded to the base material (and which is conformed with the molding of the base material), facilitates application of a bracket with an applicator. A bracket applicator and package suitable for use with the dental bracket of the present invention is also described.

An apparatus provides automatically controlled facial rejuvenation treatments and is comprised of a scanner for scanning a patient's face, a treatment robot, including a plurality of dermatological devices for treatment of facial skin, and a computer coupled to the scanner and robot for determining a treatment protocol of the patient's face based on a scanned input of the patient's face and for generating a plurality of commands for the treatment robot for movement and/or control of the plurality of dermatological devices for the automated treatment of the skin of the patient's face. A dermatological laser, needle injector, and/or air injector are used. The needle injector injects a minute amount of substance at a multiplicity of points within a computer-identified treatment area on the patient's face.

A method for producing appointment cards comprises the steps of selecting one of a plurality of patient management systems in which data retrieval is to occur. Data is retrieved according to the format assumed in the database of that selected patient management system. Both text and/or image data on the appointment card corresponding to the corresponding patient, such as image data of the corresponding patient relating to the treatment received by or to be received by the patient like dental images relating to orthodontic improvement in the patient. Selected advertisements as controlled from a remote server on the internet are printed onto the card as determined by a remote advertising sales manager or advertising schedule, selected according to patient data criteria communicated to the server, including biographical, geographic and treatment information uploaded to the server.

An apparatus for cleaning the touch screen of any personal electronic device, including but not limited to smart phones and personal computing tablets. The apparatus comprises a wet portion and a dry portion in a substantially horizontal figure “8” configuration. The apparatus may also comprise a reservoir for storing a volume of conventional cleaning fluid. When not in use, the apparatus is slid into a case which is configured to house the wet and dry portions of the apparatus in separate housing compartments. A method is also provided for storing the apparatus when not in use so as to prolong its effective lifespan and improve its overall performance.

A cold sterilizer comprises a tray for containing a sterilant and instruments to be sterilized, a lid fitting over the tray, a timer for measuring the period for which the instruments are to be contained in the sterilant to effect sterilization and means for resetting the timer to its original setting for a sterilization upon lifting the lid from the tray during the sterilization. The sterilizer may further comprise means for locking the lid onto the tray and means operatively connecting the timer to the locking means so that the locking means is locked while the timer is timing a sterilization and the locking means unlocks when the period for which the timer is set has expired. There may also be provided means for manually overriding the timer and unlocking the locking means during a sterilization and for thereupon resetting the timer to its original setting for the sterilization.
