A study guide includes a housing with a screen and a removable cartridge. The cartridge provides textual material including a plurality of questions and a set of answers for each question. The textual material is displayed on the screen and the user then selects one of the answers in response to each question. A microprocessor in the housing tabulates the answers and on demand displays a score of the total number of questions and/or the number of correct answers.

An introducer device for receiving a generally bullet-shaped obturator and for facilitating the insertion of an examination instrument into an orifice or body cavity of a patient has first and second hingeably connected half-sections. Each half-section includes a handle, a flange connected to the handle and a nose portion extending continuously from the flange. A connector secures the half-sections together to form a cylindrical hollow nose portion sized to receive and hold the obturator. The generally cylindrical hollow nose portion is large enough in diameter to receive the examination instrument when the obturator is removed.

Automated telephone attendant equipment involving a technique for connecting an incoming call on an external line to one out of a plurality of telephone devices. Each telephone device is connected in an internal line branching off from the external line. A main control box is placed in an internal line. After it senses a ring on the external line, it processes an incoming identification signal, such as is characteristic of a facsimile transmission, for example, which contains information as to which particular telephone device is to be accessed. The main control box then generates a ringback signal which not only notifies the caller that the extension desired is ringing, as is conventional, but also contains a coded signal unique to the telephone device of interest. A local control box is provided in each internal line to normally block signals from passing to the telephone device from the external line. This local control box detects the coded ringback signal from the main control box and compares it with the code preassigned to itself. If a match is found, the local control box connects its corresponding telephone device to the external line.
