摘要： A memory circuit (14) having features specifically adapted to permit the memory circuit (14) to serve as a video frame memory is disclosed. The memory circuit (14) contains a dynamic random access memory array (24) with buffers (18, 20) on input and output data ports (22) thereof to permit asynchronous read, write and refresh accesses to the memory array (24). The memory circuit (14) is accessed both serially and randomly. An address generator (28) contains an address buffer register (36) which stores a random access address and an address sequencer (40) which provides a stream of addresses to the memory array (24). An initial address for the stream of addresses is the random access address stored in the address buffer register (36).

摘要： An electronic telephone answering apparatus which receives a connection from a remote telephone and reacts according to signals from the remote telephone. In one embodiment of the invention, the answering apparatus suppresses the connection between the remote telephone and the local telephone receiver until a predetermined condition is met by the remote telephone. This predetermined condition may include staying on the line a predetermined amount of time after a message has been communicated to the remote telephone, or communicating a selected key word for connection to the local telephone, such as "emergency". This embodiment allows for the selective connection of emergency or high priority calls when the operator of the local telephone does not wish to be interrupted except for these high priority calls. In another embodiment of the invention, an incoming message is speech recognized and stored in a memory. The recognized speech is matched to a list of key words, which are input by the operator of the local telephone, for selective later retrieval when the operator of the telephone desires. This embodiment allows for the storage of key words by the operator so that at a later time, the operator is able to retrieve selective groups of messages in their operator perceived priority and therefore handle more important messages prior to addressing lower priority messages.

摘要： A circuit and method for actuating a display, especially a liquid crystal display, and a keyboard using a common set of conductors. The circuit includes circuits for generating appropriate display potentials, scanning pulses and sensing the scanning pulses. Certain of the display potentials applied to the display device are also applied to the keyboard. Certain of these potentials applied to the keyboard also have a scanning pulse superimposed thereon. Circuits for sensing the scanning pulses are associated with the circuits which generate the other potentials applied to the keyboard; these other potentials preferably float during the generation of the scanning pulses.By using the disclosed circuit, a calculator chip for actuating a multi-character position liquid crystal display and for scanning a keyboard may be packaged in a conventional twenty-eight pin package. By appropriately controlling the circuit, a keyboard can be scanned with negligible effect on the liquid crystal display device.
