A system for reducing noise when detecting the capacitance value of a capacitor in a touch display that operates in a potentially noisy environment. A capacitance sensor is provided for determining the size of the capacitor in the touch screen display and includes a charging circuit that charges the capacitor and a discharge circuit that resets the charge of the capacitor to substantially zero. A control circuit controls the capacitance sensor and the operation of the charge and discharge circuits in accordance with a predetermined charging/discharging algorithm to resolve the value of the capacitor and output such value in a sampling operation. The operation of the control circuit and the charging/discharging algorithm is subject to errors as a function of the noisy environment, which errors will be reflected in the output value. A noise reduction circuit is provided to modify the operation of the control circuit to reduce noise.

A forklift attachment is shown and described. The forklift attachment, has a mounting sleeve which includes a base, at least one sidewall, and an open end. The mounting sleeve fits and slides over a tine of a forklift. A plurality of braces is disposed along a top surface of the mounting sleeve defining a channel which extends parallel to, and forward from, the mounting sleeve. The channel includes a first end and a second end and an elongated rod is pivotally secured to the plurality of braces at the second end of the channel. The elongated rod extends parallel to, and forward from, the plurality of braces. A lock selectively secures the elongated rod in a position parallel to the tine of the forklift.

In a flat flex cable, signal lines are surrounded by logic ground planes above and below which are viaed together left and right. The ground planes coupled with the flex cable dielectric determine characteristic the impedance and attenuation of the cable and provide differential signal EMI shielding. All signal layers and logic ground planes are enclosed within the two outermost shield layers which are viaed together left and right and around the connectors to enclose both signal layers and logic ground planes to provide common mode EMI shielding.

A gardening tool may have a handle coupled to a head by way of a connector. The head may comprise a detachable, double-edged blade having a plurality of spikes. The head may include a second blade with a plurality of prongs of varying lengths. The smaller size of the gardening tool relative to many conventional tools may improve efficiency for the use, transportation, and storage of the tools.

A touch panel scan system is disclosed for detecting a change in mutual capacitance on the surface of a touch panel. A first touch detect device is provided having a transmitter for transmitting a transmit signal to a select one of a plurality of first lines on a first edge of a touch panel to facilitate a single line scan operation. A second touch detect device is interfaced with a select one or ones of second lines on a second edge of the touch panel having a receiver for receiving therefrom and processing thereof transmit signals coupled thereto from the select one or ones of the first lines to detect changes in a mutual capacitance associated with the select one or ones of the second lines and the first line. At least one of the first or second touch detect devices functions as a master and the other functions as a slave, with the master coupled to the slave and generating a SYNC signal to initiate a single scan operation of a select one of the first lines.

A system, method, and fluid analysis module are provided for the real-time analysis of multiphase fluids. The system generally comprises a sampling system for directing a fluid stream from a flow line to a fluid analysis module, a processor and communicator. The fluid analysis module comprises a sensor for measurement of at least one property of the fluid. The processor processes the measurement data from the sensor, and the communicator communicates the processed data to a central acquisition unit or computer.

An integrated circuit includes a current-based digital-to-analog converter (IDAC) including a clock input and including an output. The integrated circuit further includes a sample synchronization generator to provide a clock signal to a clock output terminal and a first timing signal related to the clock signal to the clock input of the IDAC. The sample synchronization generator controls the clock signal and the first timing signal to communicate a control signal to a peripheral module.
