Title: Burst demodulator for establishing carrier and clock timing from a sequence of alternating symbols
Inventor: YOSHIDA SHOUSEI
IPC: H04L27/38
Filed: 1990-06-13
Granted: 1993-09-21
Abstract: ABSTRACT OF THE DISCLOSURE     In a burst demodulator, an APSK burst signal containing a preamble of alternating "1" and "-1" symbols, followed by a data field is received and quasi-coherently demodulated into a baseband complex signal, which is converted to digital form such that each symbol of the complex signal yields N digital samples, with N being selected such that at least one of the N digital samples is closest to a signal point of the burst signal. A clock recovery circuit is responsive to the arrival of the burst for estimating the symbol timing of the burst signal from digital samples of the preamble. A digital sample is extracted from every N samples of the preamble in response to the estimated symbol timing so that it is most likely to be closest to the signal point. A carrier recovery circuit responds to the estimated symbol timing by estimating the carrier frequency and phase of the burst signal from the extracted digital samples to produce a complex carrier signal, which is multiplied with the extracted digital samples to recover the original signal. Memories are preferably provided to store the received burst signal. By repeatedly reading the preamble from the memories, the same symbols of the preamble can be used for clock timing and carrier phase recovery operations.

Title: Submersible marine dock system and method
Inventor: MELDRUM CHARLES R
IPC: E02B3/06
Filed: 1991-01-08
Granted: 2001-12-25
Abstract: A submersible dock system with mooring pilings which folds down for storage underwater. The dock system includes a deck or mainspan normally above water, a submerged horizontal frame and, if necessary, leveling means, and a plurality of vertical support structures extending between the submerged frame and dock. The submerged frame, vertical structures and mainspan of the deck are all preferably constructed of rectangular tubing members which are pivotally joined in key places to enable the deck to be pivoted from an upright position to a substantially supine position underwater. The dock system also includes a plurality of telescoping members to hold the deck in an upright position. The height of the dock walkway is also easily adjusted to accommodate changes in water levels. Storage of the deck and vertical structures under water is achieved by pulling pins or other fasteners out of the telescoping diagonal connecting members so that they are free to collapse by shortening or lengthening, thereby allowing the vertical members to pivot about hinged points of the deck and submerged frame. The galvanized steel tubular members are made more corrosion resistant by use of sacrificial anodes and regular perforations in the tubular members.

Granted: 1999-02-23
Abstract: The creation and ordering of custom business forms is simplified for short-run orders, allowing the end user of the business form to design and transmit the order on a personal computer.  Using appropriate design software, the business form is first designed, and then electronically transferred into a second software program which allows for the selection of a number of business form parameters, and also includes order parameters including quantity and delivery options.  The business form parameters from the design software are automatically transferred to the ordering software, and any remaining parameters that must be selected are then selected in a sequence, the order quantity and delivery information is inputted, and the price is calculated, and then the custom business form and order are transmitted in machine form to a second computer remote from the first computer.  At the second computer a confirmation of the order is produced, and the order is evaluated to determine where the best facility to print it is.  The order is then electronically transferred to the printing location, and after printing it is shipped.  The particular manner of highlighting and/or pictorially illustrating the options selectable, and a number of the particular parameters to be selected -- such as the edge along which multipart forms are to be attached -- are controlled for optimum utility.
