An implantable hearing prosthesis for a recipient patient is described. The system includes a first filter means for separating bacteria from the sample and a broth for culturing the bacteria including an inducing agent for inducing enzyme production. The computing device receives a request to present an out-of-office calendar for a portion of an organization associated with the employee and sends, to a user device, a calendar with the stored information for the employee out-of-office event that is responsive to the request to present the out-of-office calendar.
