Patent CA-2018597-A1 (CA)
Inventor: LOCKTON DAVID B
IPC: G06F19/00
Filed: 1990-06-08
Abstract: A game of skill or chance playable by several participants remote from each other in conjunction with a common event, such as a computer game, provides the basic format or template of the game on a floppy disk suitable for use with the remote users' personal computers. Then by connection to a mass communications one way channel, such as an FM SCA channel, variations in the game parameters and characteristics are broadcast at the same time to all of the individual remote players. These characteristics both initialize characteristics of the game and when the game is being played, provide updated playing parameters. A score can later be uploaded to the central station by, for example, telephone lines or any other convenient means.

Title: Serial data rate detection systems
Inventor: GUTZ STEVEN J
IPC: H04L25/02
Filed: 1990-09-20
Abstract: A  system  and  method  are  described  for  bit  rate detection in a serial data communication system,  the system  employing  a  data  rate prompt  of  a  pair  of opposite value data bits which follow a series of idle bits.  In a first embodiment a receiving port employs a clocked delay element and a set of data clock rates, each data clock rate being a multiple N of one of a set of established bit transmission rates, ranging from a highest expected bit rate to a  lowest expected bit rate.   The  bit  rate  detection  method  comprises: clocking the delay element at the highest data clock rate, upon the sensing of one of the opposite value data rate prompt bits at the delay element, to step the value of the sensed bit into the delay element.  After a  predetermined number  of  data  clock  pulses  have stepped the value of the sensed bit into the delay element, the system compares the bit value at an input to  the  delay element  and  the bit  value  in  a  bit position  of  the  delay  element.   If  the  comparison indicates an equality of bit values, the delay element is  clocked  at  a  lower  data  clock  rate  until  the comparing step indicates an inequality of bit values. At this point, the bit rate has been determined.      Another embodiment is also described wherein a pair of counters are substituted for the delay element.

Abstract: ABSTRACT         The operation of sticking stamps (3; 3') from a foil in strip form at predetermined locations on a substrate (1) which has motifs (2) printed thereon and which is pulled through at least one sticking station at a predetermined forward feed speed is effected by means of pressing portions, which are raised radially above a pressing cylinder,  in the sticking station.   The pressing portions have curved pressing surfaces which are parts of a larger cylindrical surface which is concentric with respect to the pressing cylinder and which during each sticking phase roll against a backing cylinder and transfer the stamps (3; 3') onto the substrate (1).  The strip speed of the foil may also be lower than the forward feed speed.   The foil used may be a hot embossing foil with a layer of adhesive or an embossing foil without a layer of adhesive, while the apparatus, for sticking the embossing foil onto the substrate (1), has an applicator mechanism for adhesive upstream of the sticking station (11 or 11') and an irradiation station for the activation of adhesive layers.
