Abstract:
A plurality of character forming segments are affixed to one surface of a front and back plate of a liquid crystal device. Three conductors affixed to one of the plates are each coupled to approximately one-third of the segment electrodes affixed to that plate. A plurality of conductors are affixed to the other plate and are each coupled to three of the segment electrodes affixed to that plate. Liquid crystal material is disposed between the two plates. By making use of the display device and a disclosed keyboard scanning circuit, an eight character position liquid crystal display device and a keyboard may be coupled to an electronic calculator chip disposed in a standard twenty-eight pin package.
Abstract:
Integrated circuit speech synthesis system utilizing complementary metal-insulator-semiconductor technology to achieve low voltage operation, wherein a pluse width modulated digital-to-analog converter is employed to provide for accurate conversion of digital signals into analog signals even though the low voltage operation prohibits the large voltage swings normally required for digital-to-analog converter circuitry. The speech synthesis system includes a linear predictive filter as a speech synthesizer which utilizes coded reflection coefficients to produce digital signals representative of human speech. A microprocessor controls the access of digitized speech data which is stored in a memory. The speech synthesizer and microprocessor along with the pulse width modulated digital-to-analog converter are implemented in complementary metal-insulator-semiconductor technology. The system also includes a speaker for generating audible sounds in the form of synthesized human speech from the analog signals provided by the digital-to-analog converter.

Abstract:
The user receives a digital radio transmission through a digital receiver and transmits a request to download selected content from this transmission to a content agent, an entity responsible for authorizing the authorized downloading of the digital content. If the content is not free of charge, the user also transmits sufficient information to allow for payment for the digital. The user then receives a transmission authorizing the downloading of the digital content from the content agent upon acceptance of the payment by the content agent. The user then downloads the content to a storage device which is coupled to the receiver.
Abstract:
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).
