Abstract: Methods and apparatus are disclosed for directing optical radiation to make multiple passes across an extended region of an electro-optic material, where during each pass the electro-optic material converts a portion of the optical radiation into terahertz radiation, and where the optical radiation is directed into the electro-optic material to cause an amplitude of the terahertz radiation generated from one or more earlier passes of the optical radiation to be constructively enhanced by the terahertz radiation generated from a later pass of the optical radiation.

Abstract: The invention is a handheld device for puncturing oil filters and thus allowing more retained oil to drain from used filters. An oil filter has several internal chambers filled with oil which do not drain by gravity from the filter unless the sidewall of the filter is punches. The device of the invention punches the sidewall of the filters, and provides a rack for draining the oil filters.

Abstract: A passive centralizer for stably centering within a well. The centralizer may be of a retracted profile for advancement within the well and deployable for centralization upon reaching an operation site. Deployment may be achieved in an automated manner without the requirement of operator interaction therefor. Furthermore, the centralizer may be truly passive in that energy for deployment may be stored entirely within the passive centralizer prior to its insertion within the well. The passive centralizer may also be compressed following centralization by any number of downhole restrictions. In this manner the passive centralizer may also be readily withdrawn from the well.

Abstract: The present technology relates to tamper evident films, systems and methods for detecting tamper events in films or film packages. The present technology is especially useful in applications for detecting tamper events with individually packaged goods, as well as with bulk packaging or wrapped pallets in circumstances where visual inspection is hampered or prevented. In one or more preferred systems, films and methods of the present technology utilize a conductive pattern, a sensor and/or alarm circuit, and a wrapping film, such as a stretch film, shrink wrap, bagging or stretchhooder. In at least one particularly preferred embodiment, films of the present technology are stretch films having conductive ink patterns applied thereto that remain conductive when the films are stretched to a percent stretch of about 1% or greater. In other embodiments, a conductive material can be separately wrapped and/or cowrapped in conjunction with a film.
