International Classification:

H04B 726

US Classification:

701213, 701 27, 701 35, 340438, 340439, 455 121, 455 331, 455 571, 455 581

Abstract:

A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. Each fleet vehicle has an assigned time slot to transmit its reporting information over a communications network without interfering with transmissions from other vehicles in their own respective time slots. A timing control phase lock loop (PLL) provides precise time synchronization for timing corrections from a global positioning system (GPS) based time reference. A dual band full-duplex interface of the network has TDMA on one-half and broadcast on the other half. Microprocessor time processing units in components of the network perform precise clock synchronization. Space diversity performed on received vehicle transmitted messages avoids data corruption.

Abstract:

A vehicle fleet management information system for identification of location and direction of movement of each vehicle in the fleet in real-time and automatic communication directly with management offices to report its location and heading, and status of predetermined events in which the vehicle may be engaged. One example is a cement delivery truck which monitors location, speed and status information such as start pour, pouring, end pour, wash and leave job, and automatically transmits this information with a management office without requiring affirmative action by the vehicle operator.

International Classification:

B28C 5/42

US Classification:

701 35, 366 61, 366349, 180209

Abstract:

A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager. One aspect relates to automated reporting of status of a ready mix slurry material truck having a mixer drum. A sensor detects the begin pour event by detecting the mixer drum being run in a discharge direction.

International Classification:

G06F 15/16

US Classification:

709230000

Abstract:

A wireless gateway is provided that connects mobile and remote assets or employees to business enterprise users through multiple wireless networks and the Internet by using web served applications. The central core of the gateway is a location aware business component that sends and receives location based information to and from remote and mobile assets and applies business logic to the location data to enhance and automate business applications run by the enterprise user. This functionality considerably exceeds that of a traditional wireless gateway, which simply manages messages passed through multiple wireless networks but does nothing with the content of the messages. The business logic component provides a common interface and protocol for handling location information and allows applications that follow the protocol to interface with the gateway to take advantage of location information by using location data to trigger events or to tag events, messages, or other data.

A vehicle fleet management information system identifies location and direction of movement of each vehicle in a fleet in real-time, and automatically reports such information, as well as status of predetermined events in which the vehicle is engaged, directly to the fleet manager.

A dual band full-duplex interface of the network has TDMA on one-half and broadcast on the other half. Microprocessor time processing units in components of the network perform precise clock synchronization. Space diversity performed on received vehicle transmitted messages avoids data corruption. Different vehicles have different periodic transmission intervals, by dynamically allocating the slots for various update rates. Auxiliary reporting slots enable prompt reporting of important data by the respective vehicle transmitters independent of the slower periodic transmission intervals.

International Classification:

H04B 138
H04M 100

US Classification:

455562

Abstract:

In a system for interconnecting a plurality of radio channel units in a single trunk group with a plurality of directional antennas and/or antenna beams, each radio channel unit has a receive section and a transmit section and the system dynamically connects the receive and transmit sections of each one of the radio channel units with any one of the plurality of antennas which, on average during a sampling period, is best suited for receiving and transmitting RF signals at the operating frequency of the radio channel unit. The system further includes traffic distribution monitor for monitoring, storing and displaying information on a periodic basis indicative of the usage of each antenna and/or antenna beam. The specific antenna or antenna beam being utilized by a radio channel unit is monitored on a periodic basis during communications between the radio channel unit and a mobile radio unit, and this information is stored in a memory associated with the radio channel unit.

International Classification:

H03B 2900

US Classification:

381 71

Abstract:

An electronic muffling device is disclosed for suppressing the noise emitted by an outlet of an exhaust pipe of an engine. The device comprises a housing having an outlet and a plurality of audio transducers. The transducers supply anti-noise to cancel detected unwanted noise. A microphone appropriately positioned to detect residual noise is coupled to a cancellation signal generator, which controls the anti-noise generated by the transducers. Anti-noise and unwanted engine noise propagate through a front volume within the housing so that exhaust gases are transmitted through the housing, but engine noise is canceled before leaving the housing. Exhaust gas may be transmitted into the housing, or may be passed through the housing without leaving the exhaust pipe. In either embodiment, engine noise enters the front volume and is canceled.
