Title: Re-encoding decoded signals
Inventor: FLETCHER JOHN ANDREW
IPC: G10L19/16
Filed: 1998-07-20
Granted: 2007-09-25
Abstract: If a signal is repeatedly encoded and decoded, coding noise generally accumulates as it passes through the various coding systems.  The present system provides means for preventing this, by providing means for identifying, at the second coding system, which coding system was previously used. The second coding can then use the same system as the previous coding. This use of matching coding systems results in very little extra coding noise being introduced by the second coding. The input signal is coded by two different encoders (11 and 12), their outputs are decoded and compared with the input signal at (20 and 21), the differences accumulated at (22 and 23). The smaller of the differences is used by selector (13) to select the encoder which matches the previous coding of the signal. The principles can be extended to MPEG Layer II Audio Coding and similar block coding systems.

Abstract: Detergent bar compositions comprising optional fillers with both soap and high levels of acyl isethionate surfactants are prepared.  When high levels of soap and surfactant are normally used in such a process, there is a significant "grittiness" problem. Preprocessing the isethionate containing chip (e.g., "DEFI" chip) has been unexpectedly found to remedy this problem. Preprocessing involves blending of the isethionate with fatty acid soap, optionally surfactant (e.g., betaine) and other minor components using the same process as that used to manufacture final soap (e.g., mixing components at greater than 90 °C for at least 15 minutes, cooling for example on a chill roll, and refining to form chips). The raw material so formed is collected in the form of noodles or chips and then used as the sodium acyl isethionate source in a non-molten process.

Title: Approach for routing an integrated circuit
Inventor: CHAPMAN DAVID C
IPC: H01L21/82
Filed: 1999-10-19
Granted: 2009-09-15
Abstract: A computer-implemented approach for routing an integrated circuit using non-orthogonal routing is accomplished during two phases:  a global routing phase and a detailed routing phase. During global routing, routing indicators, in the form of hint polygons, are added to the integrated circuit layout and strategy lists, that include bias directions and straying limits, are generated for the new wires to be added.  The hint polygons and strategy lists are used during detailed routing to aid in placing the new wires. If obstacle conflicts or insufficient space problems prevent the detailed routing of a new wire, then an obstacle resolution portion of global routing is used to resolve the obstacle conflict and/or provide additional space in the integrated circuit layout to route the new wires. Obstacle resolution includes, without limitation, moving or changing layout geometry, changing or add hint polygons, changing the routing strategy by changing the bias direction and/or adjusting straying limits, inserting one or more layer changes, instructing the detailed router to backup and insert a bend, ripping-up, and rerouting one or more wires, or routing the wire from the destination connection point. Also, a tight routing approach may be employed to accommodate constructing routing paths in tight layout areas.  Object specific design rule checks are employed to increase routing flexibility optimize routing performance. "On-the-fly" design rule checks are performed on portions of routing paths as the routing paths are being constructed.

Title: A wireless communication system using surface acoustic wave (saw) second harmonic techniques
Inventor: CAMPBELL COLIN K
IPC: H03H9/00
Filed: 2001-05-25
Granted: 2006-07-11
Abstract: SAW devices such as interdigital transducers (IDTs) have been widely used in RADAR applications and as filters. An IDT produces a SAW when excited by a single electrical pulse and can be fabricated to embody a code, which code provides for a passive autocorrelation of a SAW input to the IDT and thereby lends itself to further application as a signal generator in a communication device. However, internal dimensions of IDTs are inversely proportional to operating frequency, such that high frequency IDTs present significant manufacturing difficulties. Fabrication of IDTs for high frequency applications is simplified by exploiting a harmonic frequency SAW generated by IDTs. An IDT may therefore be designed according to fundamental frequency internal dimension criteria but can operate at a multiple of the fundamental frequency, thereby providing much higher frequency operation than conventional SAW systems. A communication system based on SAW harmonic techniques would be low-cost, low-power, small and simple alternative to known short range communications schemes, including for example the Bluetooth TM solution. Operation of a second harmonic SAW system at 2.4 GHz based on a fundamental frequency of 1.2 GHz is contemplated.
