Patent number: 5293349Abstract: A memory cell constructed in accordance with the present invention includes a node operable to present an electrical level representing a first state or a second state. Further included is a first switching device having a first terminal connected to the node such that if the first switching device were to close, the electrical level at the node would be connected to a second terminal of the first switching device. Additionally, second and third switching devices are provided both having first and second terminals and both operable to switch as a function of the state at the node. Finally, a single control switching device is provided in association with the second and third switching devices wherein a control signal switches the control switching device such that the state at the node may be determined by connecting to the first terminals of the second and third switching devices.Type: GrantFiled: June 24, 1991Date of Patent: March 8, 1994Assignee: Texas Instruments IncorporatedInventors: James F.

Patent number: 5029214Abstract: Electronic speech control apparatus that includes a circuit for establishing and changing over time a subject code and an utterance index. The subject code generally indicates one of a plurality of sets of utterances. The utterance index identifies an utterance of at least one word in the set indicated by the subject code. Combined with the circuit is another circuit responsive thereto for generating the utterance identified by the utterance index in the set indicated by the subject code. The apparatus also repeatedly computes an emotion and generates an utterance representing the emotion so computed. The various utterances are made in an alternating conversational fashion in response to a person's speech. These and other aspects of apparatus and method are described in greater detail herein.Type: GrantFiled: August 11, 1986Date of Patent: July 2, 1991Inventor: James F. Hollander

Patent number: 4214200Abstract: An electrical meter has light-emissive display elements and a meter circuit featuring electrically floating input terminals relative to device ground, and offers a potentially significant cost advantage compared to available alternatives in low-accuracy measuring applications.A series string of the light-emissive display elements are physically arranged along a line in order of increasing turn-on current threshold of each element so that they are successively turned on along the line with increasing current to be measured. A control circuit included in the series string has first and second semiconductively-complementary active semiconductor devices, such as an NPN and PNP transistor, each with base, emitter, and collector. The input-sensing conductor, such as a base, of each active semiconductor is a respective floating input of the meter.Type: GrantFiled: November 1, 1978Date of Patent: July 22, 1980Inventor: James F.
