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.

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. Each fleet vehicle is assigned a unique time slot to transmit its reporting information over a communications network without substantially interfering with transmissions from other vehicles in their own respective time slots. Precise time synchronization is provided by a timing control PLL which provides timing corrections as necessary from GPS based time reference. The network includes a dual band full-duplex interface with TDMA on one-half of the interface and broadcast on the other half. Additionally, time processing units of microprocessors in components throughout the network perform precise clock synchronization.

Abstract: An analog signal gain circuit includes an input receiving an analog input signal defined by an ac signal component due to a driving force and a dc offset component independent of the driving force and an output providing an analog output signal defined by an amplified representation of the analog input signal and a dc offset component corresponding to a reference signal. A digital/analog feedback circuit includes a comparator having the reference signal as a switching threshold connected to an up/down counter having a number of digital outputs. The outputs of the up/down counter are connected to a D/A converter which converts the digital count to an analog feedback signal. The feedback signal is provided to the input of the analog signal gain circuit to minimize variations in the dc offset signal component of the analog output signal by compensating for the dc offset signal component of the analog input signal.

Abstract: A media-compatible sensing structure (210) that employs strain-sensing elements (222) formed in or on a silicon chip (212). The sensor (210) generally includes a metal body (214) having a diaphragm (216) and an edge (226) formed by an abrupt change in the thickness of the metal body (214) in a direction normal to the diaphragm (216). The silicon chip (212) is secured directly to the metal diaphragm (216) and has at least one strain-sensing element (222) aligned with the edge (226) of the body (214) in the direction normal to the diaphragm (216), such that movement of the diaphragm (216) induces strain in the silicon chip (212) that is localized at the strain-sensing element (222).

Abstract: A method for making and vacuum packaging a silicon micromachined motion sensor, such as a gyroscope, at the chip level. The method involves micromachining a trench-isolated sensing element in a sensing chip, and then attaching a circuit chip to enclose the sensing element. Solder bumps serve to attach the circuit chip to the sensing chip, form a hermetic seal to enable vacuum-packaging of the sensor, and electrically interconnect the sensing chip with the circuit chip. Conductive runners formed on the enclosed surface of the circuit chip serve to electrically interconnect the sensing element with its associated sensing structures.

Abstract: A memory cell having programming voltage margin verification is provided. The memory cell includes a voltage comparator having a differential input with first and second inputs and bias circuitry for generating a differential input voltage. A voltage offset is applied to the second input of the comparator to provide an input offset voltage. A programming voltage is received for programming the memory cell and the memory cell provides an output signal. To verify an unprogrammed state voltage margin of the memory cell, a margin detection circuitry receives a verification check signal and the output is monitored to determine whether the unprogrammed state voltage margin is proper. To verify a proper programmed state voltage margin of the memory cell, current is sensed through the programming input and a determination of a proper programmed state voltage margin is determined as a function of the sensed current.
