Patent CA-2329106-A1 (CA)
Inventor: DUNCAN DAVID
IPC: H04H20/88
Filed: 2000-12-20
Abstract: A method and apparatus for compressing digital data, particularly audio and other data, in a way that the packing method used can be automatically detected and decoded at the receiving station. The audio signal is divided into compression packets consisting of four word pairs of left and right words. The first word pair in each compression packet is tagged with an identifier to indicate the start of a new compression packet, and is provided with configuration information which, over an entire compression block of 48 compression packets, constructs a 48-bit word specifying the manner in which the compressed audio and other data is packed. The method and apparatus of the invention is able to compress digital audio and other data to accommodate 16-, 20- and 24-bit resolutions and transmit up to eight channels of audio information in a variety of formats, and makes more efficient use of available bandwidth in the 16-, 20- or 24-bit output by allowing other information to be embedded into the least significant bits of the remaining available compression packet space which would otherwise be dropped.

Title: Intelligent-networked system with service for notifying and hearing selected e-mails via a public switched telephone network
Inventor: HUA SHIYAN
IPC: H04M3/42
Filed: 2001-01-25
Abstract: An intelligent-networked telecommunication system for audio playing of Electronic Mail (~E-Mail~) messages uses the Service Control Point (SCP) of the Intelligent Network (IN) to route e-mail messages directed to subscribing cus-tomers to the customer's telephone number when the e-mail header matches the limitations stored in the subscribing customer's profile. The text of the e-mail message is con-verted to an audio message which can either be heard by the customer when a call is answered, or stored on an answering machine or in a voice mailbox. The present-inventive Noti-fying and Hearing Selective E-Mails (NHSE) system and method also includes features such as the subscribing customer be-ing able to specify that audio e-mail messages will be trun-cated to a specified length, sending a special Caller ID message identifying the e-mail sender and subject of the message when the customer also has Caller ID service, and preceding the transmission of the audio e-mail message with a distinctive ringing pattern, to allow a subscribing cus-tomer the option of going ~off-hook~ to listen to the mes-sage, or allow the call to go directly to voice mail or an answering machine.

Abstract: A monitoring system for a furnace (5), such as one in which ceramic welding is practiced, where the temperature often exceeds 2000 ~F, allows substantially distortion-free, real time, monitoring. In order to monitor the furnace, a fluid cooled lance (10) designed to be held by an operator outside the furnace has a camera (13) (e.g. microcamera, endoscope or boroscope) mounted at the free end (12) of the lance. An electrical connection (18) is provided between the camera and a portable control unit (20) mounted exteriorly of the furnace.  A stationary video monitor (25) and recorder (26) may be mounted in the control unit (20), and a portable real time video monitor (28) is mounted on the operator's headgear (27) so that it may be seen by the operator when manipulating the lance. The lance is cooled by a water jacket (14) having an inlet (15) and outlet (16) at the end of the lance exterior of the furnace, and the water jacket (14) substantially surrounds the camera. The camera is mounted in a waterproof metal casing (30) and the cord (18) is covered by an aramid reinforced covering adjacent the camera. A second, sapphire, lens (33) protects the camera lens (31) from radiant heat, and air under pressure also helps cool the camera.

Abstract: A device for predistorting a transmission signal (S1) to be transmitted over a nonlinear transmission path (10) comprises an estimator (14, 16) for determining an error signal (S2') depending on the transmission signal (S1) and a previously registered transfer characteristic of the nonlinear transmis-sion path (10). The error signal (S2') represents an estimate of an error generated due to the nonlinearity of the trans-mission path (10). A time-dispersive element (18) is provided to produce a correction signal (S3) by a temporal extension of the error signal (S2'). A combiner (20) is provided to combine the transmission signal (S1) and the correction sig-nal (S3). As a result of the temporal extension of the error signal (S2'), an error signal segment in the frequency spec-trum of a transmission signal (S4) transmitted by the nonlin-ear transmission path (10) is shifted away from the useful frequency range of the transmission signal.
