Filed:

Jun 30, 1999

Appl. No.:

09/345274

Inventors:

James William Engel - Simi Valley CA
John Tomasik - Littleton CO

Assignee:

ZIH Corp. - Wilmington DE

International Classification:

B41J 1516

US Classification:

400618, 400641, 400611

Abstract:

An image forming device for separating a printable medium from a continuous protective backing strip attached thereto includes a stepped stripper roller shaft encircled by a roller sleeve adapted to press a platen of the device wherein the image forming device causes the continuous strip to pass over a stripper bar and directs the protective backing strip to move under the stripper bar and between the platen and the roller sleeve while the printable medium continuously moves out of the device from over the stripper bar.

Appl. No.:

11/533605

Inventors:

Thomas Zevin - Valencia CA, US
James Engel - Simi Valley CA, US

International Classification:

B65H 16/06

US Classification:

242571500, 242596700

Abstract:

One embodiment of the invention is a notch finding mechanism that at least partially supports and drives a core carrying printer media. The notch finding mechanism includes a notch finding spring and a plurality of support posts that extend from a support disk. The notch finding spring includes a plurality of fingers constructed of a flexible sheet material, and the fingers are positioned circumferentially and adjacent each other to define a plurality of spaces between the fingers. In addition, the fingers are biased radially outwardly, and each of the fingers has a free end that has a width that is approximately matched to a width of a notch in an end of the core. The bias of one of the fingers urges the free end of the finger into the notch aligned with the finger when the core is placed over the fingers and is rotated a small amount.

US Classification:

34082554

Abstract:

In a data message communication system, certain messages require a return acknowledgement signal. The present invention contemplates a method and means which are activated whenever an outbound message is received. Each portable unit which receives a message then monitors the outbound communication channel to determine if the inhibit signal is currently active. If the inhibit is not currently active, the particular unit will transmit its acknowledgement message immediately. If the inhibit signal is active, each portable unit will maintain a count of the number of outbound messages, addressed to other units requiring an acknowledgement, since that particular portable received its message. At the termination of the inhibit signal, each portable unit will pause for a period equivalent to the product of the acknowledgement message time slot multiplied by count of messages accumulated since the receipt of the particular portable units message. Each portable unit will then transmit an acknowledgement signal at the termination of its unique pause period.

International Classification:

G01C 100

US Classification:

73514

Abstract:

An integrated accelerometer includes hinges of silicon composition for securing the strut legs of a pendulous mass to the accelerometer body. Both the body of the accelerometer and the pendulous mass are of metal-coated compositions. Metallized pads are provided on selected surfaces of the hinges for forming eutectic bonds with the body and struts of the pendulous mass of the accelerometer. A heavily-doped continuous region adjacent the surface of the hinge connects the eutectic bonds through a flexure region of reduced thickness to complete necessary device circuitry.

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.

Motorola, Inc. - Schaumburg IL

International Classification:

H04Q 700

US Classification:

375100

Abstract:

A radio data communications system is disclosed in which messages, normally lost to interference caused by independent remote units contending for the radio channel, may be salvaged. If a remote unit communicating a message to a fixed site is interrupted by a second remote unit having a stronger radio signal, the fixed site detects the increase of radio signal strength and activates a synchronization detector which responds to a synchronization data bit sequence which precedes each data message. If the synchronization sequence is detected, the remainder of the first remote data unit message is discarded and the message of the second remote data unit is processed.

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.
