Patent number: 9438677Abstract: Multiple packets are received that were transmitted by multiple mobile electronic device sensors located in a predefined area. The packets each include data detected by the sensors of multiple mobile electronic devices. At least a portion of the collected data is stored including multiple unique device identifiers that belong to multiple mobile electronic devices. Responsive to determining that at least two of the unique device identifiers are sequential, a set of values based on the at least two unique devices identifiers are associated as belonging to a same one of the mobile electronic devices.Type: GrantFiled: April 15, 2014Date of Patent: September 6, 2016Assignee: Euclid Inc.Inventors: Kenneth Man-Kin Leung, William Tolbert Smith, Steve Lawrence Wilhelm

Patent number: 4478318Abstract: An improved brake control apparatus for a brake system having redundant brake application fluid circuits 30, 32 and a brake retraction fluid circuit 62. A valve assembly 34, including a slidable two position valve element 60 communicates one brake application fluid circuit 30 with the retraction circuit 62, during normal brake actuation. The valve element 60 is biased towards one position by the combination of pressure in the other brake application circuit 32 and a resilient biasing arrangement 68, and biased towards the second position by pressure in the one application circuit 30. In the event of failure in the other application 32 circuit, the loss of biasing fluid pressure causes the valve element to shift to the second position, interrupting fluid communication from the one application circuit to the retraction circuit and drains fluid pressure in the retraction circuit into the failed circuit.Type: GrantFiled: May 14, 1982Date of Patent: October 23, 1984Assignee: Euclid, Inc.Inventor: Ronald D. Hayden

Patent number: 4437530Abstract: A driving axle assembly (10) comprises a differential mechanism (34) driving axle shafts 36, 38, first and second gear reduction (40) are connected to the axle shafts remote from the differential mechanism for driving vehicle wheel assemblies (14, 16). The differential mechanism and gear reductions are supported by an axle assembly support housing comprising a housing frame (50) supporting the differential mechanism and first and second spindle assemblies (52, 54) attached to the frame and projecting to the respective gear reductions.Type: GrantFiled: July 16, 1982Date of Patent: March 20, 1984Assignee: Euclid, Inc.Inventors: Simon A. De Young, Charles C. Gray

Patent number: 4431091Abstract: An automatic purge valve 110 for removing air and/or vapor from a fluid pressure operated brake system. The valve comprises a chamber 120 disposed in a brake assembly that includes a pair of opposed coaxially aligned valve seats 120b, 134b and a valve member 130 disposed in the chamber and engagable with either of the seats. The seat 134b communicates with a brake coolant system 58; the other valve seat 120b communicates with a piston retraction fluid chamber 90. The valve member is biased towards the one valve seat 120b by pressure in the coolant system and is driven toward the other valve seat 134b during brake actuation by fluid pressure in the piston retraction fluid chamber. Air and/or vapor is discharged from the retraction fluid circuit into the coolant circuit as the valve member travels from the seat 120b to the seat 134b each time the brake assembly is actuated.Type: GrantFiled: January 7, 1982Date of Patent: February 14, 1984Assignee: Euclid, Inc.Inventor: Harold R. Scibbe

Patent number: 4140304Abstract: A vehicle ride strut includes first and second tubular housing members having open ends telescoped together. A compression spring is compressed by telescopic movement of the housing members relatively toward each other, and a snubber resiliently resists movement of the housing members in a direction away from each other during ride strut extension.Type: GrantFiled: December 12, 1977Date of Patent: February 20, 1979Assignee: Euclid, Inc.Inventor: Roy W.
