Abstract: A handle for an oral-care implement for safe and hygienic use by multiple users includes an electrical motor and a detachable head. The handle has a display for displaying instructions to control functional operation of the handle, a microcontroller for controlling the motor and the display, and at least one switch to allow a user to control the functional operation of the handle, including causing the output element to vibrate in at least one oral-hygiene mode having an oral-hygiene frequency and causing the output element to vibrate in a disinfection mode when the handle is being disinfected before or after being used for the oral-hygiene routine. The disinfection mode has a modulated frequency, different from the oral-hygiene frequency, and alternating up and down between a low modulated frequency and a high modulated frequency, wherein the high modulated frequency is at least 50 percent greater than the low modulated frequency.

Abstract: A connector alignment assembly is provided for aligning memory modules in a test position relative to a memory module tester. An automatic feeder receives, stages and then dispenses the electronic memory modules onto a conveyor, one at a time. The conveyor moves the electronic memory modules from the feeder to a test station. A contact plunger is used to push tester contacts against surface contacts of the electronic memory module to electrically connect the electronic memory module to test circuitry. The connector alignment assembly includes two alignment pins which are mounted to the contact plunger, such that when the contact plunger is moved to press the test contacts against the surface contacts, the alignment pins are moved into two alignment holes of the electronic memory module.
