Title: System and method for encoding an audio signal, by adding an inaudible code to the audio signal, for use in broadcast programme identification systems
Inventor: SRINIVASAN VENUGOPAL
IPC: G10L25/51
Filed: 1998-11-05
Abstract: An encoder is arranged to add a binary code bit to block of a signal by selecting, within the block, (i) a reference frequency within the predetermined signal bandwidth, (ii) a first code frequency having a first predetermined offset from the reference frequency, and (iii) a second code frequency having a second predetermined offset from the reference frequency. The spectral amplitude of the signal at the first code frequency is increased so as to render the spectral amplitude at the first code frequency a maximum in its neighborhood of frequencies and is decreased at the second code frequency so as to render the spectral amplitude at the second code frequency a minimum in its neighborhood of frequencies.  Alternatively, the portion of the signal at one of the first and second code frequencies whose spectral amplitude is smaller may be designated as a modifiable signal component such that, in order to indicate the binary bit, the phase of the modifiable signal component is changed so that this phase differs within a predetermined amount from the phase of the reference signal component. As a still further alternative, the spectral amplitude of the first code frequency may be swapped with a spectral amplitude of a frequency having a maximum amplitude in the first neighborhood of frequencies and the spectral amplitude of the second code frequency may be swapped with a spectral amplitude of a frequency having a minimum amplitude in the second neighborhood of frequencies. A decoder may be arranged to decode the binary bit.

Inventor: ANTHONY WILLIAM STANLEY
IPC: B07B1/46
Filed: 1999-06-29
Abstract: A method for separating non-fibrous particulates from fibers. A pulverized mixture of non-fibrous particulates and fibers is introduced into a separation zone (24) containing a plurality of revolving spiked cylinders (30). Revolving spikes of the respective revolving spiked cylinders contact and separate fibers from the pulverized mixture to produce non-fibrous particulates. The separated fibers have residual non-fibrous particulates which may be removed by the revolving spikes of one revolving spiked cylinders throwing or impelling the separated fibers against and into the revolving spikes of a contiguous revolving spiked cylinder. When the separated fibers impact the spikes of the contiguous revolving spiked cylinder, residual non-fibrous particulates loosen and separate from the removed fibers. The produced non-fibrous particulates have residual polyester fibers which may be removed and reclaimed.

Abstract: A process for determining lateral overturning of a vehicle involves establishing a threshold value line S separating a lateral overturning region farther from an origin and a lateral non-overturning region closer to the origin on a two-dimensional map made using a rolling angle .theta. and a rolling angular speed .omega. of the vehicle. When a hysteresis line for actual rolling angles and actual rolling angular speeds of the vehicle traverses the threshold value line from the lateral non-overturning region to the lateral overturning region, it is determined that there is a possibility of lateral overturning of the vehicle, and correspondingly an occupant protecting system may be deployed. Also, to assure accuracy, a lateral acceleration sensor for detecting a lateral acceleration for establishing the threshold value line S is disposed on a center plane of a vehicle body.

Patent CA-2342054-A1 (CA)
Inventor: GREEN DAVID K
IPC: E21B34/02
Filed: 2001-03-26
Abstract: A well control system having well controlled fluids distributed through pipes includes valves that are opened by a heat softened valve obstruction element. The translation of a fluid flow obstructing gate in a gate valve is driven by a stem element attached to the gate. Without a mechanical or fluid obstacle, fluid pressure in the distribution pipe above about 2 psi will drive the valve gate to a biased position. This internal pressure displacement of the valve gate also displaces the gate stem. In the present invention, the displacement of gate stems for critical valves from a normal maintenance position to an emergency activation position, is obstructed by a fusible barrier that is secured across the gate stem translation path. In the event of a well fire, at a predetermined temperature of fusion, the barrier element will no longer resist the displacement force imposed by the stem. The internal pipe pressure on the stem will force penetration of the stem through the fusible barrier thereby permitting the valve to open and release fluids into the well for the purpose of plugging uncontrolled well flow and extinguishing the fire.

Abstract: The stent has a proximal portion in a main segment which incorporates a series of angulated struts and flexible omega-shaped connectors. The dista l segment of the main portion of the stent is of a variable design. The distal portion of the main leg is designed to have added flexibility without compromising the expansion diameter of the stent. The distal portion of the side branch segment is designed to offer more flexibility to accommodate challenging side branch angles. The main portion of the stent and its distal side branch portion are connected by a hinge connector firmly joined to both the main branch and the distal branch. This hinge connector is extremely flexible and allows for multiple variations in the vasculature of the patien t. The particular delivery system used with this bifurcated stent encompasses a double-balloon system. The first balloon is placed in the main segment along its entire length. The second balloon is placed within the side branch .  Thus, when the stent tracks (in other words, is passed) along the artery, t he segmented distal portion of the stent is able to fit nicely into the side branch of the vasculature.
