On the date of the Bingo game, the player chooses which preselected Bingo numbers to play. The player is provided with a ticket having the preselected numbers with a control number (58) for each set of numbers and a validation number (60) for the ticket. The player is also provided with a receipt indicating the number of preselected sets of numbers bought by the player and the validation number for the ticket. The Bingo game is then played with them called Bingo numbers being entered into the computer. When a player calls BINGO, the hall enters the control number of the potentially winning set of numbers into the computer to verify the set of numbers is a winner. To collect his prize, the player must present his receipt having the correct validation number.

Patent CA-2358223-A1 (CA)
Inventor: PEARSON MICHAEL
IPC: H04N5/347
Filed: 2001-10-03
Abstract: The invention disclosed is directed to a method and apparatus which allows a "rolling shutter" type of read out sequence in a pixel array that is read using a double sampling technique by having the rows of pixels reset a second time in each of their cycles for a second sampling while the rows are being accessed for reading. In this way, each pixel is sampled to compare its voltage level after integration to its voltage level as it is reset. In accordance with the present invention, the row access signal or a signal that is used to generate the row access signal, is used to generate a second reset signal at the correct time while the row is being accessed. The invention is particularly applicable to image sensors having light sensitive elements that are CMOS pixels, and in particular three transistor pixels.

Title: Wrap-ons aromatic thermal wraps
Inventor: JOHNSTON SCOTTIA E
IPC: A61F7/02
Filed: 2001-10-03
Abstract: An aromatic thermal wrap comprises aromatic compounds such as camphor, menthol, essential oils and similar compounds, mixed with an absorbent material such as a silica powder and then combined with a superabsorbent polymer (SAP) to form a dry, aromatic mixture (200), and packaged in a flexible, water-permeable sachet (100). When suitably mixed with a silica powder, the aromatic compounds do not cause agglomeration or clumping of the superabsorbent polymer. Hydration of the sachet will cause the SAP to absorb water, forming a gel 210. The sachet may be produced with multiple pockets (110) that can be separated into single packets or into sets of packets to accommodate the specific application. The end user hydrates the sachet, and optionally heats or freezes the hydrated package, to produce an aromatic, thermal wrap.
