Title: Method and apparatus for transmitting data
Inventor: KAWAI NOBUYUKI
IPC: H04L1/16
Filed: 1997-07-28
Abstract: Data relating to the status of users 12 in a mobile communications system is broadcast via satellite 8 from a network register 4 to local registers 10 in an HDLC format. Each of the local registers 10 requests retransmission of any HDLC frames which are incorrectly received. The network register 4 records the earliest transmitted frame not yet acknowledged by all of the local registers and inhibits transmission of new frames if they fall outside a transmission window relative to the earliest transmitted frame. The network register 4 polls the local registers 10 for retransmission requests and the local registers 10 also send unsolicited requests to the network register 4. The network register 4 only retransmits a frame once if multiple requests for that frame are transmitted within a predetermined period.      When a new local register 10 enters the broadcast reception group, the network register 4 informs the new local register 10 which new frame will next be transmitted.      The number of bits used for frame sequence numbers is greater than that defined in the HDLC protocols.

Filed: 1997-07-30
Abstract: This invention relates to cigarette makers and in particular to planar devices that can be folded from a single sheet of material into free standing three dimensional cigarette makers for inserting pre-formed tobacco sticks into tubular cigarette papers.   Cigarette makers can be complex,  expensive devices incorporating  plungers  inter-linked  with  cylindrical  shaped chambers.   These devices are often sold separately from the cigarette paper tubes and tobacco rods and are therefore often lost or misplaced prior to actual use.  What is provided by the present invention is a cigarette maker, foldable from a single sheet of material, that is inexpensive, easy to construct and use and which can be packaged in a kit along with tobacco sticks and cigarette paper tubes or constructed from the very same packaging material used to package the cigarette kit.

Abstract: Two light signals (L1',L2') pass, in opposite directions, through a series circuit comprising a first optical fiber (4), a first polarizer (5), a Faraday sensor device (3), a second polarizer (6) and a second optical fiber (7). To set the working point, additionally, the planes of polarization of both light signals are reciprocally rotated by a predetermined angle of rotation by rotation means (8) between the two polari-zers. From light intensities (I1, I2) of the two light signals (L1,L2), after passing through the series cir-cuit, a measuring signal (M) is determined which is independent of vibrations and bending influences in the optical fibers.
