Title: Processing of audio signals during high frequency reconstruction
Inventor: KJOERLING KRISTOFER
IPC: G10L19/032
Filed: 2011-07-14
Abstract: An audio encoder applies a high frequency reconstruction (HFR) process to generate a high frequency component of an audio signal from a plurality of low frequency subband signals. The encoder includes means to generate control data indicative of whether to use a plurality of spectral gain coefficients in the HFR process. The spectral gain coefficients are associated with the energy of the respective plurality of low frequency subband signals. The encoder includes means to analyse an audio signal and to determine a degree of spectral envelope discontinuities introduced when regenerating the high frequency component from the low frequency subband signals. The control data is generated based on the degree of discontinuities. Associated methods relate to generating control data, encoding and decoding audio signals.

Patent CA-2931441-A1 (CA)
IPC: A61M25/095
Filed: 2016-05-26
Abstract: Nasogastric tubes are utilized during esophageal and foregut surgical procedures. In traditional surgical procedures ("open" surgery), a surgeon is able to manually palpate (feel) the stomach or esophagus in order to position the nasogastric tube. Minimally invasive procedures eliminate the tactile feedback from the surgeon, resulting in surgeons having to rely on other approaches in order to determine the position of a tube. A luminous feedback apparatus is inserted into a nasogastric tube for positioning the nasogastric tube at the time of minimally invasive thoracic and foregut surgery. The luminous feedback apparatus includes integrated light source, power supply, manually controlled switch, and light conduit. When the luminous feedback apparatus is activated and inserted into a nasogastric tube, the light conduit produces visible light at the tip of the nasogastric tube and can be seen through tissue such as esophagus or stomach wall, providing visual feedback on the position of the nasogastric tube.
