Abstract: An international time indicating system is associated with a telephone for automatically displaying a specific time and date of a called place upon entering the international access code, called country code, and called area code if necessary. A called time and date are calculated via time zone offsets stored in system memory by determining the difference in time between a time zone of a local place of a caller and a time zone of a called place. The offsets are defined with respect to a reference time zone. The difference in time is then offset in order to determine the called time.

Abstract: A portable wireless telephone including a main unit of small volume to which an antenna, an earpiece and a microphone are connected. The means for composing a number to be called include a display system (4, 5, 13) in which the digits making up the number to be called can be displayed, one after another, by the manipulation of a crown (10). Such crown can be rotated (60) then pressed (61) in order respectively to choose a digit then confirm it and continuing thus until said number is entirely composed. The telephone can be advantageously combined with a timepiece.

Abstract: A combined wristwatch and radiotelephone has a portion such as a wristband which typically remains on the user's wrist, and a timekeeping and radiotelephone portion which is typically removable from the portion that remains on the wrist. The wristwatch and radiotelephone portion is reconfigurable between a relatively compact form in which it is suitable for wearing on the wrist as a wristwatch, and a more elongated form in which it is suitable for use as a hand-held radiotelephone with a microphone and speaker spaced sufficiently far apart to permit simultaneous use of those components adjacent the user's mouth and ear.

Abstract: A combined wristwatch and radiotelephone has a plurality of substantially rigid segment members arranged end to end in a series with pivotable connections between each adjacent pair of members in the series. The pivotal axes of these connections are substantially parallel to the longitudinal axis of the user's wrist when the apparatus is worn on the wrist as a wristwatch. The pivotable connections allow the apparatus to be curved into a shape which fits around the user's wrist when the apparatus is to be used as a wristwatch. Alternatively, the pivotable connections allow the apparatus to form a more elongated structure suitable for use as a hand-held radiotelephone when such use is desired.

Abstract: A wristwatch radiotelephone mechanism has three substantially rigid members connected to one another in a series by connection mechanisms connected between adjacent members in the series. The connection mechanisms allow the members to be arranged either in a C-shaped array when the apparatus is to be worn on the wrist as a wristwatch, or in a more elongated array when the apparatus is to be used as a hand-held radiotelephone.

The rigid members house a radiotelephone speaker, microphone, display, dialing buttons, and control buttons. A wristwatch strap joins the free ends of the rigid members so that the rigid members may be worn around a wrist when arranged in a compact unit.

Abstract: A wristwatch radiotelephone having a plurality of telescopically arranged substantially rigid members and a flexible strap member joined to the proximal end of the endmost rigid member. The rigid members house a radiotelephone speaker, microphone, display, dialing buttons, and control buttons. When the rigid members are extended, the radiotelephone is accessible and the flexible member is contained within the rigid members. When the rigid members are collapsed, the flexible member may be extended around a wrist to attach the rigid members and radiotelephone to a wrist.

Abstract: A timer for automatically controlling the cumulative service time of a telephone consisting of a box mounted over and plugged into a standard wall telephone outlet. The box contains an exterior receptacle for connection with the telephone cord. The interior of the box is secured by a locked cover that prevents access to the controls as well as to the mounting screws that fasten the unit to the outlet box. The desired total amount of time of phone use permitted during each 24 hour period is selected by setting appropriate control switches and it remains unchanged until a new selection is made. At the expiration of the selected cumulative service time, the timer alerts the user of the impending disconnection by a tone signal and automatically disconnects the phone soon thereafter. The device is powered by a battery backed utility 110 VAC source and it resets itself automatically every 24 hours, so that no periodic adjustments or calibrations are required.
