Title: Call me conference call system
Inventor: BUSHNELL WILLIAM JACKSON
IPC: H04M3/58
Filed: 2000-08-14
Abstract: A "Call Me" conference call system includes a multiport conference unit (MCU) interconnected with the public switched telecommunications network (PSTN), a telecommunications switching system also interconnected with the PSTN, a service control point (SCP) or other intelligent network control component having at least a signaling connection to the switching system, a Call Me conference bridge reservation system interconnected with the SCP and the MCU, and suitable facilities interconnecting these components. When a conference reservation is made, information regarding the conference is distributed to the SCP and MCU. A "Called Party Busy" trigger is applied to the conference host's line. To join the conference, the host and participants alike simply call the host's telephone number. The switching system, finding the host's line busy, queries the SCP, which instructs it to redirect the call to the MCU. The MCU associates the call with a reserved conference by matching the called number with a host's telephone number in reservation records. This advantageously avoids the need for hosts to distribute, and participants to receive a special conference bridge telephone number or access code.
Patent CA-2318815-A1 (CA)
Title: Method and apparatus for integrating manual input
Inventor: WESTERMAN WAYNE
IPC: G06F3/0488
Filed: 1999-01-25
Abstract: Apparatus and methods are disclosed for simultaneously tracking multiple finger (202-204) and palm (206, 207) contacts as hands approach, touch, and slide across a proximity-sensing, compliant, and flexible multi-touch surface (2). The surface consists of compressible cushion (32), dielectric electrode (33), and circuitry layers. A simple proximity transduction circuit is placed under each electrode to maximize the signal-to-noise ratio and to reduce wiring complexity. Scanning and signal off-set removal on electrode array produces low-noise proximity images. Segmentation processing of each proximity image constructs a group of electrodes corresponding to each distinguishable contacts and extracts shape, position and surface proximity features for each group. Groups in successive images which correspond to the same hand contact are linked by a persistent path tracker (245) which also detects individual contact touchdown and liftoff. Classification of intuitive hand configurations and motions enables unprecedented integration of typing, resting, pointing, scrolling, 3D manipulation, and handwriting into a versatile, ergonomic computer input device.

Title: Support element for fragile structures such as catalytic converters
Inventor: FERNANDO JOSEPH A
IPC: B01D53/86
Filed: 1999-02-18
Abstract: A support element (20) is disposed between a housing (12) and a fragile structure (18) resiliently mounted within the housing (12). The support element (20) includes an integral, substantially non-expanding ply or layer of melt-formed ceramic fibers containing at least alumina and silica. The fibers have an average diameter ranging from about 1 micron to about 14 microns and have been heat treated by treating the fibers at a temperature of at least 1100 °C over a 30-minute period, or at a temperature of at least 990 °C for a period of at least on hour. The resultant heat treated fibers exhibit suitable handling properties, have at least about 5 to about 50 percent crystallinity as detected by x-ray diffraction, and have a crystallite size of from about 50 A  to about 500 A. The resultant support element (20) provides a minimum residual pressure for holding the fragile structure (18) within the housing (12) after 200 cycles of testing at 900 °C of at least 4 psi. Such a support element (20) may be used in devices for the treatment of exhaust gases, such as catalytic converters (10), diesel particulate traps and the like. A method of mounting a fragile structure (18) in such a device is also provided.

Abstract: The invention relates to a method for producing knitted goods in general, hose in particular, with tridimensional effects or shaped goods, preferably fitted with at least one pocket automatically produced with the continuous motion of the needle cylinder. The usual knitted fabric production is modified by excluding, according to a preestablished order, sequences of needles (retaining the last loop or stitch) that are preferably alternated (1:1 - 2:2 -3:1 - etc.), even by groups. The knitted tube production goes on, even over several courses, with a differentiated growing, i.e. regions having full needles or ribs and regions having non-full needles or ribs, forming knitted layers or tubes (5, 6) concentric with the inner knitted tube folded upwardly and only partly interstitched or closed in the horizontal direction. The remaining part, which is open, corresponds to the two-layer pouch-like pocket, being the object of the invention.

IPC: H04L12/12
Filed: 1997-02-07
Abstract: A system is disclosed for providing direct automated access to an online information services provider through an address embedded in a video or audio program, commercial message, or news story. The system operates with video or audio programs which are received through broadcast. cable or pre-recorded media, and which are encoded in either analog or digital formats.      The address of an online information provider is encoded in a vertical blanking interval or other non-displayed portion of an electronic signal which represents the video or audio program so as not to interfere with the program as displayed or transduced on a television or audio sound system. The online information provider address is detected and decoded from the electronic signal and used in establishing a direct digital communication link to the online information provider.      Upon detecting an online provider address, the system indicates to the user that more information is available. The user may then elect to establish a connection with the online information provider by giving a simple command, e.g., pushing a special button on a remote control. The system then automatically establishes a direct digital communication link to the online information provider through the address and provides for interactive information exchange and processing to permit signals received from the online information provider to be displayed on a conventional television, transduced on a sound system, or also on a high resolution reproducing system such as a computer monitor, or other reproduction device.
