Digitally Programmable Rf Mems Filters With Mechanically Coupled Resonators, Hengky Chandrahalim, Sunil Ashok Bhave

AFIT Patents

A digitally-tunable RF MEMS filter includes a substrate and a plurality of mechanically coupled resonators, wherein a first and a last resonator of the plurality of mechanically coupled resonators are configured to be electrostatically transduced. One or more of the plurality of mechanically coupled resonators are configured to be biased relative to the substrate such that the one or more biased resonators may be brought substantially in contact with the substrate. In a method of digitally tuning an RF MEMS filter having a mechanically coupled resonator array, a DC bias voltage is applied to at least a first resonator and …

Mosaic Imager Using Wave Front Control, Mark T. Gruneisen, Matthew B. Garvin, Raymond C. Dymale, James R. Rotge

AFIT Patents

A wave front control system ("WFCS") organizes the object scene into a mosaic comprised of a grid of segments and transmits each segment in a temporal sequence. The WFCS steers the light fronts emanating from each segment, one segment at a time, through a series of optical components that transmit the light fronts respectively emanating from each segment onto a digital imaging sensor. An optical recording device records each sensed segment, and the object scene is composed by assembling the recorded segments. This abstract is provided to comply with the rules requiring an abstract, and is intended to allow a …

Automated Flagger Assistance Devices (Afads), David Jones

Purdue Road School

This presentation discusses the pros and cons of using various Automated Flagger Assistance Devices (AFADs). It reviews both AFADs using STOP/SLOW signs which are currently allowed in Indiana, and Red/Yellow signal faced AFADs that are not allowed in Indiana.

The presentation points out that the principle reason for developing AFADs was to enhance worker safety by enabling flagger/operators to position themselves out of harm's way while controlling work zone traffic. However, the dominant reason for buying them seems to be to save money by only using one flagger/operator.

Various applications using AFADs are reviewed as well as potential changes to …

Alternate Bidding History And Requirements, Tom Duncan, David Holtz

Purdue Road School

On November 18, 2009 the Federal Highway Administration (FHWA) approved the innovative contracting process of the Indiana Department of Transportation (INDOT) for alternate pavement bidding on multiple projects. This process involves only one set of plans with the choice to bid either Portland Cement Concrete Pavement (PCCP), or Hot Mix Asphalt (HMA) Pavement, or both typical pavement sections. A Present Worth (PW) cost was calculated for future maintenance costs of both pavement types using an established Life Cycle Cost Analysis (LCCA) Strategy. This PW cost was added to the respective pay items after the bids were opened, but the PW …
