Title: Apparatus and method for transmitting digital data over a radio communications channel
Inventor: CHILDRESS JEFFREY S
IPC: H04L1/12
Filed: 1988-05-12
Granted: 1991-04-23
Abstract: APPARATUS AND METHOD FOR TRANSMITTING          DIGITAL DATA OVER A RADIO COMMUNICATIONS CHANNEL     ABSTRACT OF THE DISCLOSURE   a digital radio RF signalling protocol communicates either digitized voice or digital data signals and indicates the type of information being communicated to the receiver.  Multiple repeats of control signals are provided for fade protection and to ensure correct receipt even under adverse communications channel conditions.  When the destination transceiver received a transmitted digital data burst from the transmitter, the destination transceiver transmits a responsive acknowledge message and may specify in the acknowledge message which portions of the received message were received incorrectly and should be retransmitted by the originating transceiver.  The originating transceiver determines the contents of subsequently-transmitted data bursts based upon the information it receives from the destination transceiver by way of the acknowledge message.  As deleterious phenomena (e.g., noise and/or fading) degrade communications channel quality, the acknowledge message handshaking causes the originating transceiver to repeat incorrectly received data packets until the destination transceiver finally receives those data packets correctly.

Granted: 1993-04-20
Abstract: ABSTRACT OF THE DISCLOSURE            A tool is described for assembling a length of sealing strip onto a mounting flange around a door opening in a motor vehicle.  The strip has a channel-shaped gripping part whose walls are initially splayed apart so that it is an easy fit onto the flange.  It carries a tubular sealing  part.   The  tool  comprise  a  roller  which engages the outside of the base of the channel of the gripping  part  and  a  perpendicularly  mounted  roller which engages the outside of the tubular sealing part of the  strip  and,  via  this  sealing  part  which  it compresses,  exerts  a  side  force on  the corresponding wide  wall  of  the  channel  of  the  gripping  part.   A flange rigid with the roller engaging the gripping part itself engages the opposite side wall of the gripping part.   The  two  rollers  may  or  may  not  be  geared together and are driven via a flexible drive shaft by a motor.  The tool thus travels along the length of the sealing  strip  which  is drawn  off  a  coil  or  other supply.   As  the  tool  travels,  it  closes the splayed apart walls of the gripping part towards each other so as  to  press  them  firmly  into  gripping  and  sealing contact  with  the  surfaces  of  the  flange,  in  which position they subsequently hold themselves.
