Title: Self-locking support for digitizer cover
Inventor: KOUHIA KENNETH
IPC: G06F3/041
Filed: 1990-07-12
Abstract: ABSTRACT OF THE DISCLOSURE A digitizer tablet is disclosed having a movable cover and a support which automatically stably holds the cover open when the cover is opened.  The digitizer tablet comprises a base structure, a cover pivotably con-nected thereto and a support coupled to the cover and to the base structure for automatically holding the cover open when it has been pivoted to its open position.  The support is constructed to self engage in the open posi-tion such that the application of a substantial force to the support is required to unlock it from the open posi-tion.  Preferably, the support includes a spring resiliently urging the support to self engage in the open position.  The support comprises a first support arm pivotally connected at one end to the cover and a second support arm pivotally connected at one end to the base structure, the first and second support arms each includ-ing an opposite end which are pivoted together.  The cover is automatically held open once opened by the con-figuration of the arms and by a stop limiting pivoting of the first and second arms relative to each other to a predetermined angle.

Abstract: ABSTRACT OF THE DISCLOSURE          A mechanism for dolls which allows for crying, movement of the lips and swivelling of the eyeballs.  The mechanism includes a control circuit and timing element which is connected to a switch placed in the mouth of the doll, a magnetic field detector placed in the proximity of the mouth, a voice apparatus, and a motor attached to a mechanism for moving the lips and eyes.          The latter mechanism consists of an eccentrically mounted shaft which is attached to one end of a spring having its other end connected to a piece that ends in the shape of an arrow-head connected to the doll face in the proximity of the mouth of the doll.  A pacifier inserted in the mouth of the doll, opens the switch to maintain inactive all the devices. If the pacifier is removed, the voice device is activated.  A bottle having a magnetic element can be inserted into the mouth, and operates the magnetic field detector to start the motor and operate the lips and the eyes.  Upon removal of the bottle the whole mechanism stops; the timing element starts and after an interval the voice device reactivates.
