Title: C-pile wall method
Inventor: HWANG JIA-SHYONG
IPC: E02D5/36
Filed: 1996-09-10
Granted: 1997-12-11
Abstract: This concerns a method for constructing underground structures, especially earth retaining walls, underground continuous walls, cut-off walls, caissons of big piers, etc.. The method involves a 'C' shaped, hollow-core pile and a special drill bit. The drill bit is driven into the earth to dig out the soil, while, the C shaped pile is lowered into the soil after it. In this way, several C shaped piles are embedded tightly together in the soil one after the other. After embedding the C shaped piles, concrete is poured into their hollow core, thus, producing a continuous,water-tight, underground wall.

Title: Detection and prevention of channel grabbing in a wireless communications system
Inventor: DAVID N HOOGERWERF
IPC: H04L29/06
Filed: 1996-11-28
Granted: 1997-11-21
Abstract: A method and system for detecting a voice channel grab by a pirate in a cellular telephone network. Initially, RF signals transmitted to and from an authorized cellular telephone over the control and voice channels are monitored to track call processing activities and obtain various data that are used to detect potential voice channel grabbing attempts. The data may include such things as RSSI, change power output messages and responses, and hook-flash signal, From the data, the system looks for two events. A first event is an unexpected change or an absence of an expected change in the voice channel RF signal indicating that the pirate may be transmitting on the voice channel. The first event may be any one or more of the following: (1) a sudden upward shift in the voice channel RSSI; (2) an unexpected phase shift of either the RF signal or the SAT signal contained in the RF signal; and (3) an absence of an expected shift in the RSSI that corresponds to the change power level message from the network. The second event is receipt of a message indicative of a request to establish a new telephone connection such as a hook-flash message initiating a call conference. When the unexpected change in the RF signal and the message indicative of the request to establish the new telephone connection are detected, the system determines that the voice channel assigned to the authorized cellular telephone has been grabbed by the pirate. When the system determines that the channel grab has occurred, it prevents the pirate from establishing the new telephone connection by preventing receipt of dialed digits or terminating the connection on the voice channel.

Granted: 2000-01-01
Abstract: The present invention relates to a method and an apparatus for image factor conversion using a suitable edge enhancement wherein plural sets of gradient thresholds and enhancement thresholds are separately corresponding to a predetermined enhancement mode. An enhancement mode of an average pixel value corresponding to an one-dimensional pixel array comprising a to-be-updated center pixel and pixels adjacent to said center pixel is determined, such that one set of the gradient threshold and the enhancement threshold corresponding to the selected enhancement mode can be selected. After the resolution is calculated by summing up the absolute values of the difference between the center pixel and each adjacent pixel, one enhancement threshold in one set of the gradient threshold and the enhancement threshold is selected by comparing said resolution with said gradient threshold in said selected set of the gradient threshold and the enhancement threshold. When the selected enhancement threshold is added to the value of the center pixel, the sign of said selected enhancement threshold is determined causing the difference between the left brightness and the right brightness to be increased.
