GMC ACADIA / ACADIA DENALI New for 2014: Forward Collision Alert and Lane Departure Warning, standard on Denali and available on SLT-1 and SLT-2 Two charging-only USB ports on the rear of the center console for second-row use 2014 GMC ACADIA HIGHLIGHTS SAFETY, CONVENIENCE FEATURES With its reputation for comfort, performance and efficiency, GMC Acadia has remained a popular choice since it was introduced as the brand’s first crossover SUV in 2007. Its luxury-minded Denali model, which came to market in mid-2010, has widened this midsize crossover’s appeal to customers looking for a high level of style, power and functionality. In 2014, the Acadia focuses on safety with the addition of Forward Collision Alert and Lane Departure Warning, crash-avoidance systems that use a camera and sensors to help detect when the driver is getting too close to a vehicle ahead, or when the vehicle enters another lane without the use of a turn signal. The systems alert the driver with visual cues on the dashboard, as well as audible signals. They complement Side Blind Zone Alert and Cross Traffic Alert, which were added in 2013. The camera technology was recently named a “Top Ten Tech Breakthrough of 2012” by Popular Mechanics. The new model year also brings an additional convenience feature: two charging-only USB ports on the rear of the center console to power up electronics from the second row. Acadia’s lineup for 2014 includes the SLE (with SLE-1 and SLE-2 trims), the SLT (with SLT-1 and SLT-2 trims) and the Denali models, with seven- or eight-passenger configurations. A 3.6L V-6 VVT engine that uses gasoline direct injection technology powers all Acadia models, optimizing performance and fuel economy across the board. The engine is paired with Acadia’s fuel-saving six-speed automatic transmission to help give FWD models an EPA-estimated 24 mpg on the highway. The transmission controls provide quick and consistent shifts for a commanding feel behind the wheel. All-wheel drive is also available. Towing capability for the Acadia is 5,200 pounds (2,364 kg), when...

This Document explains how to edit the flattened route of a Harness Drawing in SolidWorks Electrical 3D. Flattened representations of a SolidWorks Harness can be difficult to read in its default state. With the “Edit Flattened Route” command, a high quality representation of the flattened route can be created with ease. 1) Once the Harness is routed in 3D, there is a new routing sub-assembly in the FeatureManager Design Tree. 2) Right Click the routing sub-assembly and select “Flatten Route.” 888.688.3234 | GOENGINEER.COM 3) Select the type of flatten route (defined below) and select the different drawing options that are required in the Flattened Drawing. Select OK (Green Check Mark). a. Annotation allows the creation of a flattened configuration that is displayed using the standard drawing sheet with views b. Manufacture allows the creation of a flattened configuration that is displayed true size on a formboard. 888.688.3234 | GOENGINEER.COM 4) A flattened harness assembly and a flattened harness drawing is created and opened. The Flattened Harness Drawing will be the file that is displayed. If the Harness assembly is too complex the flattened representation can be cluttered. 5) Open up the Flattened Harness Assembly. Go to Window and select the file. Alternatively, use Cntl+Tab to get to the right document. 888.688.3234 | GOENGINEER.COM 6) Right Click the AnnotateFlattenedRoute# and select “Edit Flattened Route.” 7) There are 5 tools that aid in editing the flattened route a.

An input amplifier for a FM-radio receiver with RF selection (88-108 MHz) has been designed in the radio project. It has about 25 dB gain in the frequency rang 88-108 MHz. Mirror frequency rejection is between 5 dB to 9 dB. Noise figure is about 7 dB at resonant frequency. The amplifier works well, when it is connected to the rest of circuits to receive FM broadcast signals. The input amplifier with RF selection (88-108 MHz) should have low noise, high gain and frequency selection. The specification of the amplifier is as follows:low noise, maximum 2dB more than Fmin gain: Gt ≥ |S21|2 mirror frequency rejection: 20 dB generator impedance: 50Ω load impedance: 50Ω ... In order to fulfill the specification, an appropriate transistor was first chosen and its S-parameters were measured. The input stage has been designed by using a common-emitter amplifier. To compromise between gain and noise, an appropriate operating point is necessary. The amplifier has an inductor tap parallel resonant circuit at its collector to restore the amplifier gain. The frequency of the parallel resonant circuit can be shifted by changing the value of the parallel capacitor. The detail of the project design will be described in chapter 2. Different measurements and results can be found in chapter 3, followed by the conclusion in chapter 4. Chapter 5 is acknowledgement and reference is in chapter 6. In the project, BFR92A transistor is used. It has high power gain, low noise figure and low intermodulation distortion. To compromise between gain and noise, an appropriate operating point should be first considered. From figure 1 (gain as a function of collector current), figure 2 (gain as a function of frequency) and figure 3 (minimum noise figure as a function of frequency), an appropriate operating point was decided. IC = 10mA, VCE = 10V. The values of Fmin and opt for the operating point are not available in the datasheet, but from circles of constant noise figure for other operating points, one can see that Fmin in the project is between 1.7 dB and 2.4 dB.
