A toothbrush holder adapter is provided which consists of an integral, unitary component with a toothbrush receiving section and a rear section adapted to be inserted into the holes or openings in a wall-mounted toothbrush holder. The synchronization signal is implemented as a reference or reset signal from which the alarm units derive a reference time to begin activation of the alarm units. Measuring sphincter pressure is accomplished through the use of a fluid-filled tube placed through the sphincter and attached to a module implanted within the bladder. The memory unit can be incorporated in programmable devices and a programmable device configuration can select either the read bypass paths or the width decoding logic. The manual grip is rotatable while the retaining pin is in the withdrawn position between a locked position in which the housing holds the manual grip with the retaining pin in the withdrawn position and an unlocked positioned in which the manual grip is linearly translatable in a second direction to return the retaining pin to the extended position.
