Title: Data communication method and apparatus using multiple physical data links
Inventor: DRETZKA ELLEN ELIZABETH
IPC: H04L29/06
Filed: 1986-11-18
Granted: 1990-01-09
Abstract: - 37 -DATA COMMUNICATION METHOD AND APPARATUS USING MULTIPLE PHYSICAL DATA LINKS Abstract A multi-link interprocessor communication protocol that allows a pair of processors to increase the speed of their communication by using multiple physical links in parallel. When a message is sent from one processor to another, the message is packetized into smaller segments and loaded onto the available physical links according to a simple algorithm. The individual packets are received at the other end, their accurate transmission verified, and the received packets are then reassembled in the proper order. Packets of one or more messages to the same destination can go over the same physical link, or over different physical links; that is, there is no association of any message to any particular physical communication link. Packets received out of order on a per logical channel basis are stored until a correct sequence of packets is received after which their transmission to the message destination is effected. The reordering of packets is accomplished using a multi-link header advantageously comprising only a single byte.

Title: Time division multiplexing method with channel compression and a device therefor
Inventor: AIKOH SHINICHI
IPC: H04J3/17
Filed: 1987-12-22
Granted: 1991-02-19
Abstract: ABSTRACT OF THE DISCLOSURE     In a time division multiplexing method or device wherein first through N-th-channel samples are extracted at first through M-th unit intervals which correspond to first through M-th bit rates of first through N-th-channel input signals, where M is equal to or less than N, a control signal is produced in response to the input signals to indicate first through M-th consecutive fields in each of successive frames of a time division multiplexed signal and to indicate whether the samples are significant or insignificant samples in the respective frames.  The first through the M-th fields correspond to the respective unit intervals and have a predetermined total time duration in each frame.  The control signal is used moreover to arrange the samples in the fields of the respectlve frames by selecting the significant samples with preference to the insignificant samples.  Together with the control signal, a sample arrangement information signal is produced to indicate arrangement of the samples in the respective frames and is arranged in an information field which remains in each frame.  Depending on the number of the samples arranged in each field with the unit interval corresponding to the field under consideration, time durations of the respective fields may vary from frame to frame.  An insignificant sample may be discarded in (Abstract of the Disclosure continued) order to arrange in a certain frame in order to arrange a discarded sample which becomes a significant sample in the frame in question, in which event the sample arrangement information signal indicates the channel number of the significant sample in place of that of the discarded sample.

Abstract: Abstract of the Disclosure A method for contact fusion bonding of compressible, low density thermoplastic parts is disclosed, which comprises essentially: (a) fluidizing only a surface film on opposed mateable margins of the thermoplastic parts by precompressing the margins against a transversely stationary heated platen located therebetween and, prior to fluidization, continuing such contact to promote such fluidization by thermal conductivity and make heat settable a limited, predetermined, nonmelted subsurface layer of said mateable margins; and (b) within a time period during which said surface films remain fluid, withdraw said platen from between said opposed margins with minimal separation while bringing the mateable margins together with sufficient force to merge said fluid films and compress said subsurface layers a predetermined moulded dimension.         The time period during which the fluid films must be merged after removal of the heated platen is typically less than one second for most low density thermoplastics (low density here being used to mean less than or equal to 2.5 lbs/ft3).

Title: Automatic focusing circuit using a two period detection interval to compensate for motion occurring within a field of view
Inventor: MURASHIMA HIROTSUGU
IPC: H04N5/232

Granted: 1992-05-26
Abstract: jrr ABSTRACT OF THE DISCLOSURE In  an  automatic  focusing  circuit  of  a  video camera, an automatic focusing operation is performed by a focus evaluating value produced in response to a video signal obtained in an image sensing circuit.  A focusing motor control circuit controls rotation of a focusing motor so that a focusing lens is once fixed in the position where the focusing evaluating value takes the maximum value. Then,  a control circuit resumes the automatic focusing operation after a lapse of a second time period when it is determined that the focus evaluating value was decreased to a predetermined  level  during a  first time period and maintained the level over the second time period, and does not resume the automatic focusing operation when it is determined that the focus evaluating value did not maintain the level.  On the other hand, the control circuit resumes the automatic focusing operation after a lapse of the first time period when it is determined that a time period which is more than the first time period is required until the focus evaluating value attains the predetermined level.
