Patent MX-9703319-A (MX)
Title: Optical multilayer information carrier.
Inventor: BRAAT JOSEPHUS JOHANNES MARIA
IPC: G11B7/24041
Filed: 1996-08-29
Abstract: A record carrier is described, which has standard and high-density information layers. The standard density layer (2), e.g. in a standard CD format, is positioned at the bottom of a substrate, and is read out through the substrate with a laser beam. The thickness of the substrate is within the CD specification, e.g. 1.2 mm. At least one high-density layer (3) is formed by a material which is (nearly) transparent for the laser wavelength of standard CD players ('lambda' = 780 nm), but is (at least partially) reflective for shorter wavelengths used for high-density discs ('lambda' = 635 nm). To achieve a high density, a smaller track pitch and smaller pits are used in the high-density layer(s). To achieve better reading signals from both layers, the high-density layer is positioned closer to the side of entrance of the laser beam in the substrate. This enables a higher numeric aperture of the focusing lens and, therefore, a smaller spot for the shorter wavelength. The high-density layer is preferably positioned midway in the substrate e.g. at 0.6 mm, because in that case the high-density layer configuration will be compatible with two-sided high density discs which have a total thickness of 1.2 mm. The information content of the standard layer may be duplicated on the high-density layer, or it may be represented by a different coding scheme.

Patent MX-9706914-A (MX)
Title: Scanning laser demolding of ophthalmic lenses.
Inventor: BEATON STEPHEN R
IPC: B29D11/00
Filed: 1997-09-10
Abstract: An apparatus and method for removing a molded ophthalmic lens from between the mold portions in which it is produced. A source of intense electromagnetic radiation is applied to at least one of the mold portions in a predetermined scanning pattern through the intermediary of galvanometer- driven mirrors. Differential expansion of the heated mold polymer relative to the cooler polymer shifts one surface with respect to the other, and the shear force breaks the polymerized lens/polymer mold adhesion and assists in the separation of mold portions. The greater the temperature gradient between the surfaces of the mold portions, the greater the shearing force and the easier the mold portions, the greater the shearing force and the easier the mold portions separate. The heated back mold portion is promptly removed so that very little energy is transferred to the polymer lens, avoiding the possibility of thermal decomposition of the lens.

Patent MX-9800652-A (MX)
Title: Transmission of data on multirate networks.
Inventor: GOETZ IAN
IPC: H04W88/18
Filed: 1998-01-21
Abstract: Mobile radio units (11, 21) communicate with their respective base stations at a lower bit-rate than the conventional switching rate of a fixed network. When communication is made between a mobile user (11) and a conventional subscriber to the 64 kbit/s PSTN system, or between such a conventional subscriber and a receiver (21). Such calls are identified by mobile to mobile recognisers (17 and 27) which identify characteristic bit streams and handle calls appropriately. The first mobile to mobile recogniser (17) is located at the fixed side of the air interface (14) and, for a normal call routes the call to the digital to A-law transcoder (15). The mobile to mobile recogniser (27) identifiers calls coming from the 64 kbit/s switch (10), and for a normal call routes the call to the high bit-rate digital to A-law transcoder (26) as described above with reference to Figure 2. If a call is established between two mobile users (11, 21) the mobile to mobile recogniser (17) identifies such a call, for example by number recognition in the call set up phase and diverts the signal received over the air interface (14) to a bit stuffer (18). The bit stuffer (18) creates (64) kilobit frames from (16) kilobit frames by providing three null bits for every bit received over the air interface. The null bits may be random numbers, but preferably include a recognisable pattern which can be detected by a second mobile to mobile recogniser (27). By "bit stuffing" in this way a 64 kbit/s signal can be generated from a 16 kbit/s signal with minimal signal processing and without the need to transcode to A-law and back. The mobile to mobile recogniser (27), may be controlled, either by recognition of the identity of the calling number, or by recognition of the characteristic pattern of null bits in a bit-stuffed signal generated by bit stuffer (18), and routes the signal to bit stripper (28) instead of to the high bit digital-to-A-law transcoder (26). The bit stripper removes the null bits and transmits only the signals making up the original 16 kbit/s signal. These are then transmitted over the air interface (24) to the low-bit-rate to A-law decoder (23), and thus to the A to D converter (22) and the listener (21).
