Patent number: 5711804Abstract: Oxide coatings are formed with a desired crystallographic texture over a large surface area. A metallic substrate is electrodeposited or vacuum deposited with a preferred crystallographic orientation, and a sol-gel/thermal process is used to form a "pseudo-epitaxial" oxide coating having crystallites that are influenced by the crystallographic orientation of the substrate. In one embodiment, p-type nickel oxide coatings with desirable electronic properties are produced by sol-gel/thermal processing on nickel substrates electrodeposited from a sulfamate nickel bath at a relatively high current density and low temperature. The electrodeposited nickel substrate has a strong Ni{100} preferred orientation. Epitaxial effects during sol-gel/thermal formation of NiO on the electrodeposited substrate enhance the extent to which the NiO{100} and NiO{111} crystal facets are aligned parallel to the coating surface, and minimize the NiO{110} orientation.Type: GrantFiled: May 3, 1996Date of Patent: January 27, 1998Assignee: Rockwell International CorporationInventors: D.

Timing recovery scheme for packet speech in multiplexing environment of voice with data applications
Patent number: 5699481Abstract: Multiple speech bit-stream frame buffers are used between the controller and the speech decoder. Whenever excessive or missing speech packages are detected, the speech decoder switches to a special corrective mode. If there is too much, the buffered frames are played out fast; if there is too little the buffered frames are played out slowly. For the fast play, some speech information has to be discarded, while for the slow play some speech-like information has to be synthesized. The speech may be handled in sub-frame units, which may be 52 samples at a time. Low energy, silent or unvoiced sub-frames, which also indicate non-periodicity, are detected and manipulated. Moreover, the decoded signal is manipulated at the excitation phase, before the final LPC synthesis filter, resulting in a transparent perceptual effect on the manipulated speech quality. Additionally, the buffers are enlarged such that the problem caused by controller asynchronicity is eliminated.Type: GrantFiled: May 18, 1995Date of Patent: December 16, 1997Assignee: Rockwell International CorporationInventors: Eyal Shlomot, Michael J. Simpson, Qiang Ye -

Patent number: 5694521Abstract: A variable speed playback system exploits multiple-period similarities within a residual signal, and includes multiple-period template matching which may be applied to alter the excitation periodical structure, and thereby increase or decrease the rate of speech playback. Embodiments of the present invention enable accurate fast or slow speech playback for store and forward applications without changing the pitch period of the speech. A correlated multiple-period similarity measure is determined for an excitation signal within a compressor/expander. The multiple-period similarity enables overlap-and-add expansion or compression by a rational ratio. Energy variations at the onset and offset portions of the speech may be weighted by energy-based adaptive weight windows.Type: GrantFiled: January 11, 1995Date of Patent: December 2, 1997Assignee: Rockwell International CorporationInventors: Eyal Shlomot, Albert Achuan Hsueh

Patent number: 5689615Abstract: A method for efficient coding of non-active voice periods is disclosed for a speech communication system with (a) a speech encoder, (b) a communication channel and (c) a speech decoder. The method intermittently sends some information about the background noise when necessary in order to give a better quality of overall speech when non-active voice frames are detected. The coding efficiency of the non-active voice frames can achieved by coding the energy of the frame and its spectrum with as few as 15 bits. These bits are not automatically transmitted whenever there is a non-active voice detection. Rather, the bits are transmitted only when an appreciable change has been detected with respect to the last time a non-active voice frame was sent. To appreciate the benefits of the present invention, a good overall quality can be achieved at rate as low as 4 kb/s on the average during normal speech conversation.Type: GrantFiled: January 22, 1996Date of Patent: November 18, 1997Assignee: Rockwell International CorporationInventors: Adil Benyassine, Huan-Yu Su

Patent number: 5689351Abstract: A method and apparatus are provided for reducing speckle noise in images read out from holographic memories. An image recorded in the memory is read out using a multiple component readout beam, with each component having the same horizontal orientation but a different vertical orientation. Because the Bragg effect is pronounced only in the horizontal direction, the readout beam components all access the same stored image. Each readout beam component is set to oscillate at a slightly different frequency such that the smallest frequency difference is greater than the reciprocal of the output detector response time. The multiple oscillating readout beam components can be produced by an acoustooptic deflector driven by a wideband electrical signal. The memory readout comprises multiple reconstructions of the desired image, with each image reconstruction oscillating at a slightly different optical frequency.Type: GrantFiled: December 7, 1995Date of Patent: November 18, 1997Assignee: Rockwell International CorporationInventor: John H.

Patent number: 5679093Abstract: An engine control provides rapid decrease in the output speed of the engine when an upshift of the transmission is being actuated. The system selectively actuates a speed retardation system to decrease the engine output speed to match a desired engine output speed at the next highest gear ratio. In one embodiment, an engine control actuates engine braking to achieve this rapid speed reduction. In other embodiments, an additional load may be placed on the engine, such as the actuation of a fan. An operator is preferably provided with a shift intent switch that provides an indication to the engine control that an upshift will be actuated. The engine control waits for an indication that the transmission has been moved to neutral. Once this indication is received, the speed retardation system is actuated to rapidly reduce the engine output speed toward a desired value.Type: GrantFiled: July 27, 1995Date of Patent: October 21, 1997Assignees: Rockwell International Corporation, Detroit Diesel CorporationInventors: Thomas Desautels, Edward M.
