Title: Sediment mat
Inventor: PETERSON ALLEN M
IPC: E02B3/12
Filed: 1993-08-18
Abstract: ABSTRACT OF THE DISCLOSURE      The present invention features a dual-purpose sediment mat for trapping loose sediments that have been disturbed upstream in a riverbed.  The mat is generally rectangular in shape and laid horizontally on the riverbed.  The low horizontal profile provides a mechanism by which the sediments can be entrapped without unduly disturbing the flow of the river.  The sediment mat has a highly porous top surface and a tightly woven bottom surface to entrap the sediments settling thereupon.  The mat itself is a loose arrangement of excelsior, straw or other sediment-absorbing material.  Wooden stays define modular portions of the sediment mat, maintain its configuration and provide handles for moving the mat.  Eyelets disposed at the corners and along the sides of the mat provide a mechanism for staking the mat to the riverbed.  Thereafter, the sediment-rich mat can be anchored to the sides of the riverbank.  There, it can be seeded to grow vegetation that beautifies and stabilizes the berm.  The sediment mat can be fabricated in rolls of various sizes or shapes for ease of storage, transportation and use.

Patent CA-2110149-A1 (CA)
Inventor: HORI TSUGUO
IPC: H04W52/04
Filed: 1993-11-26
Abstract: A high-frequency-signal detecting circuit is capable of smoothing a mean power in each time slot, and of performing rapid response during a transition time. A detector detects the envelope of a radio-frequency signal whose power level may change depending on the time slot.  A filter narrows the pass band in the data field of each time slot, and broadens it in the transition field of the same.  The output of the detector is applied to the filter.   The detecting circuit,  therefore, produces an output which is smoothed in the data field without regard to the content of data, and which sharply responds to a change in the power level in the transition field.
