Publication number: 20120179358Abstract: The characteristics of two intersecting roadways are compared to determine whether an inference can be made as to whether there are traffic controls (e.g., stop signs) on one of the roadways. If a larger road with characteristically higher speed intersects with a small road with lower speed, the small road is determined to have a stop sign. A map database is updated with the information regarding the inferred traffic control, and that information is then usable for purposes such as trip planning.Type: ApplicationFiled: March 21, 2012Publication date: July 12, 2012Applicant: ON TIME SYSTEMS, INC.Inventors: PAUL A.C.

Publication number: 20110037619Abstract: A traffic routing system reduces emissions from commuter and other traffic, eases congestion on roadways, and decreases transit time by use of communications among vehicles and traffic controls, such as traffic lights. In one aspect, a traffic light receives a signal that a vehicle is approaching and in response turns green to allow the vehicle to pass without impairment. In another aspect, a vehicle receives a signal to adjust a current rate of speed to arrive when a traffic signal allows vehicles to pass. In still another aspect, a combination of congestion, emergency traffic, roadwork and similar factors influence proposed routes sent to vehicles.Type: ApplicationFiled: December 16, 2009Publication date: February 17, 2011Applicant: ON TIME SYSTEMS, INC.Inventors: Matthew L.

Patent number: 7508868Abstract: A system abstracts channel information from field data gathered in actual wireless communication system environments. The abstracted data is then transformed into control signals or programming codes that can be used to control channel simulators so as to recreate the field conditions, including path loss, slow fading, fast fading, path delay, fading power spectral density with and without line-of-sight (LOS), and different kind of handoff scenarios, such as soft, softer, intra-band hard, inter-band hard handoffs. The system thus can accurately simulate a realistic wireless communication link originated from multiple signal sources in different band channels and formed by multipath signal propagation. The simulated realistic wireless communication link can be condensed by selecting the most useful scenarios from its original field data files or modified by tuning its parameters as desired.Type: GrantFiled: December 2, 2005Date of Patent: March 24, 2009Assignee: Kyocera Wireless Corp.Inventor: Paul C.

Patent number: 7434285Abstract: An adjustable pulsating submersible (10) is taught consisting of, a lower pool sweep body (20) with a resilient skirt (22) attached underneath. An integrated valve (50) is positioned within the lower pool sweep body and is used to accomplish a preliminary pre-selected flow adjustment. An upper pool sweep body (88) is placed over the integrated valve and is attached to the lower pool sweep body with threads in no more than one quarter turn. A flow adjuster (102) is slid tightly into upper pool sweep body and includes a number of first flow openings (104). A flow gate (106) is slid onto the flow adjuster and may rotate within limits with the flow adjuster. The flow gate incorporates a number of second flow openings (108) aligned with the first flow openings, when the flow adjuster is manually rotated the second flow openings misalign with the first flow openings providing precise adjustable flow operation.Type: GrantFiled: March 1, 2008Date of Patent: October 14, 2008Inventor: Paul C.

Patent number: 6615864Abstract: A pool cleaner reed valve for a pulsating submersible swimming pool cleaner which has a valve body (22) configured to fit into a pulsating valve enclosure. The body includes a rectangular inlet end (24) and an round outlet end (26) with a pair of fulcrum points (30) and restricting boundaries (32) for retaining and confining valve movements. A pair of opposed rigid valve plates (50) are angularly juxtaposed within the valve inlet end contiguously engaging the fulcrum points and respective restricting boundaries such that each opposed blade rotates inwardly on the fulcrum point until the distal ends intimately engage as influenced by negative fluid pressure applied by a pool pump. A pair of torsion springs (70) surround each restricting boundary and interface with each valve plate returning them to a parallel position when fluid pressure is terminated. A resilient sleeve (72) is positioned on each spring for eliminating a metal to metal contact with the spring to the valve plate.Type: GrantFiled: January 29, 2002Date of Patent: September 9, 2003Inventor: Paul C.

Patent number: 6098228Abstract: A diaphragm valve for a pool cleaner which utilizes a conventional cleaning head (30) attached with a mounting foot (32) to a cleaning disc (34). A screen (36) is inserted into the foot and an outer sleeve (38) is mounted within the head leaving a gap (40) in between. A restricting jacket (56) is slideably mounted on the sleeve and is urged into a position that restricts a water flow path from the gap, by an adjustable bypass valve (68) superimposed on the jacket. A compression spring (96) maintains the jacket position and a valve diaphragm (98) receives pool water from a pool pumping system and oscillates open and closed causing the cleaner to be propelled by a hydraulic pulsation. When the diaphragm is momentarily closed the bypass valve permits the jacket to be slid to an open position by negative pressure of pool water bypassing the diaphragm permitting full water flow through the cleaner.Type: GrantFiled: February 17, 1999Date of Patent: August 8, 2000Inventor: Paul C.

Patent number: 5992451Abstract: An improved valve for a pulsating submergible pool cleaner having a valve body (20) with an integral relief valve (32). The valve is dual acting and utilizes a pair of opposed laminated valve plates (50) with an outward bend (52) on one end and a right angle bend (54) on the other. When negative pressure is applied to the opposed plates, each plate draws together over a fulcrum (26) until the right angle bend touches a restrictive boundary in a cage (28) integral with the body creating the first step in the dual action. When negative pressure continues, the valve plates arcuately bow until the outward bends contiguously abut, closing the valve to fluid flow and creating the final step in the dual action. A garter spring (60) pulls the valves plates into their original parallel position when pressure is relieved.Type: GrantFiled: March 9, 1998Date of Patent: November 30, 1999Inventor: Paul C. Chang

Patent number: 5655246Abstract: A pulsating submergible pool cleaner which has a hollow body (24) connected to a pool pump through a flexible hose. An integrated reed valve (42) and relief valve (44) receive the full flow of water from the pump, with the reed valve closing, forcing the relief valve open generating hydraulic cyclic pulsations. An inlet mounting foot (74) is attached to the hollow body and a flexible circular debris removing disc (80) is removably connected to the foot. The foot and disc engage the submerged surface by the suction of the pool pump, and the cleaner is propelled around the pool surfaces by the cyclic pulsation generated by the integrated valves. Debris is removed and ingested into the cleaner by the scrubbing action of the disc, combined with high velocity water flow entering the body under the disc through small passageways. A leaf catching net (96) may be added as an accessory for collecting large debris, such as leaves of plants.Type: GrantFiled: April 22, 1996Date of Patent: August 12, 1997Inventor: Paul C. Chang
