Title: Remote control television system using supplementary unit for simplified personalized control
Inventor: SKINNER KENNETH ROMAYN
IPC: H03J1/00
Filed: 1990-12-13
Abstract: The system (10) includes a state of the art complex television (20), a complex remote control transmitter device (100) for use by the technically oriented user in both programming and, if desired, controlling the television, and a simple auxiliary remote control transmitter device (200) for the less technically oriented user. The simple auxiliary remote control has a minimum of keys (210), such as power on (210e), channel up (210c), channel down (210d), volume up (210a), and volume down (210b), as well as a switch (220) which identifies the user. Different power on and channel up and down codes for each switch position is provided by the simple remote device (200), and each such code is different than the corresponding codes of the complex remote (100). In this manner, a microprocessor (30) in the television will recognize which user is in control. By using the complex remote, values for personal preference parameter and/or channel rings associated with each user may be entered and stored in a programmable memory (40) of the television. Then, when the television recognizes the power on code for a particular user, the personal preference parameter and/or channel rings are immediately accessed. In this manner, less technically oriented users may be the beneficiaries of complex personal preference rings programmed for them by a highly technically oriented user, and will only have to deal with a simple remote control device to control the television.

Abstract: Coordination of test sequences to be run simultaneously by individual testers for conformance testing of multi-user systems to their specification is achieved in accordance with the present method. In order to utilize the present invention, it is necessary to generate a test sequence, desirably, one of minimum cost, which covers all aspects of the specification for the multi-user system under test. For many standard test sequence generation techniques, it is preferable to represent the multi-user system as a finite state machine. The test sequence is then divided into several different test sequences corresponding to individual testers wherein each of the different test sequences can be run simultaneously by individual testers. Then, the separate test sequences are inspected to identify instances where coordination is required among the various multiple testers which are expected to run the tests simultaneously. After the coordination instances are identified, additional instructions coordination primitives are inserted into the original test sequence for each tester to permit effective coordination between all testers. Coordination signalling is performed on an out-of-band communication media between the testers.

Abstract: A power supply for vacuum fluorescent displays has a source of a relatively high frequency signal which is provided to a power driver amplifier which is also supplied with a desired supply voltage. The output of the driver amplifier is a square-wave signal varying between approximately zero and the supply voltage; this signal is provided to the filament of the vacuum fluorescent display such that the filament is heated and is self-biased at a DC level which is substantially one-half the supply voltage level. Self-biasing a capacitor between the filament and ground, which also allows the RMS level of the voltage across the filament to be controlled by controlling the frequency of the output signal from the driver amplifier. The voltage may be regulated by comparing the RMS voltage across the filament with a reference and using the difference to control the frequency of oscillation of the source. A voltage multiplier may be connected to receive the square-wave output from the driver amplifier to produce a higher level DC voltage which can be used to supply the grid and plate drivers with the higher voltage needed for these elements. Two driver amplifiers may be connected together with circuitry to self-oscillate, with the outputs of the two amplifiers being connected across the filament to heat the filament and self-bias the filament at one-half the DC supply voltage level.

Abstract: A download system for programming decoders for redundancy. Auxiliary fuse banks (10, 15) have sets of nonvolatile storage elements, such as fuses that store logic states that (a) select a redundant decoder and (b) indicate the address of a faulty row/column of memory cells (MEMORY MARCO n). When the chip (100) is first powered up, each set of nonvolatile storage elements (10A, 10B, 15A, 15Z) is accessed and downloaded to program selected redundant decoders. Because the sets of nonvolatile storage elements can be dynamically assigned to redundant decoders on an any-for-any basis, the fault tolerance of the redundancy system is enhanced.

Abstract: A first interlayer dielectric film layer is formed on a semiconductor substrate (21). The first interlayer dielectric film (22) is made of a BPSG film formed by atmospheric pressure chemical vapour deposition method. First connection holes (24) are formed at specified positions of the first interlayer dielectric film layer. A first conductive film layer (23) is formed in a region including at leas the first connection holes. The first conductive film layer is composed of three layers by sequentially laminating a barrier metal film (23A), an aluminium alloy film (23B), and an anti-reflection film (23C). On the first conductive film layer formed in a specified pattern, a second interlayer dielectric film layer (26) is formed. The second interlayer dielectric film layer is composed of a lower layer (26A) of silicon oxide film, an intermediate layer (26B) of silicon oxide film made of inorganic silica or organic silica, and an upper layer (26C) of silicon oxide film. Specified portions of the second interlayer dielectric film layer are selectively removed. The removed regions become second connection holes (25). A second conductive film layer (27) is formed thereon. The second conductive film layer is composed of two layers: a refractory metal film (27A) as a lower layer and an aluminium alloy film (27B) as an upper layer. Thus, the second conductive film layer is not moved easily by the stress of the passivation film formed above. at the same time, formation of voids in the second connection holes is prevented, and increase of resistance of wiring is kept to a minimum. Hence, a semiconductor device with reduced reliability problems and a method for fabricating such a device are disclosed.
