Filed:

Appl. No.:

7/859231

Inventors:

Eugene J. Bruckert - Arlington Heights IL

International Classification:

H04Q 100

US Classification:

34082525

Abstract:

A method and means for controlling transmissions among a plurality of communication units is described that determines an inhibit state based upon an inhibit signal and information in a header preceding a coded message before allowing transmission. This inhibit state prevents all of the other remote units from transmitting while a prescribed remote unit transmits a coded message or an acknowledgment (ACK) so that collisions between messages and ACKs, or between one ACK and another, are avoided. Message-message collisions are substantially reduced since the method causes a remote unit to utilize a random delay before attempting a retry to send the message a second time. Hence, the method and arrangement better coordinates inbound transmissions to the base station so that collisions on the inbound channel to the base station are minimized.

Abstract:

An album includes a full color cover and a number of pages secured therein. Also secured within the album is a removable cardboard viewer including a tinted transparent filter. A flap is provided that serves as a handle for the viewer. The viewer also includes a tear away area containing a check list with numbers corresponding to each sticker that may be collected and secured in the album. Printed throughout the album pages are sequentially numbered boxes corresponding in size and number to full color, self adhesive stickers which are purchased separately from the album. A story line is also printed under a number of the designated boxes describing a story portrayed on the sticker. Printed within a number of these boxes is a photographic half tone image of the full color images on a corresponding sticker. All the photographic half tone images throughout the album are printed in a first color. Printed over all the half tone images in a second color is a patterned design which has the effect of camouflaging or obscuring the photographic half tone images.
