A spectrophotometric transillumination method and apparatus are directed to non-invasive, continuous, atraumatic, in vivo, in situ monitoring of metabolism in a body organ. In the described applications, measuring and reference wavelengths within the near infrared region, i.e., 700-1300 nm, are util ...
In the process of recovering minerals, such as hydrocarbons from shallow tar sands, and the like, one method is to create a shallow horizontal fracture within the tar sand. The size and shape of the perimeter is determined, and one or more secondary boreholes are drilled to the formation inside of t ...
A speech analyzer with improved pitch period extraction and improved accuracy of voiced/unvoiced decision comprises circuits for calculating autocorrelation coefficients forwardly and backwardly with respect to time. Reference members for the forward and the backward calculation are those successive ...
An improved telemetry transmission system for transmitting electrocardiographic information, indications of the occurrence of the pacing pulse and for transmitting digitally encoded information from an implanted pacemaker, an implanted drug dispensing device, or other implanted device, to a remote r ...
A portable instant bar code reader including a hand-held reader unit having a flash type illuminator. The flash type illuminator is triggered to illuminate a bar code label positioned adjacent to a light receiving window of the reader. Reflections from the bar code label are transmitted through the ...
A mirror assembly capable of providing an image of high or low brightness is pivotally supported by a housing or other stationary support, for movement between two operating positions to provide the high and low brightness images. For automatic actuation of the mirror assembly, a light sensitive ele ...
An RF-excited radial-flow, cylindrical plasma reactor (10) includes a toroidal waveguide (17) of rectangular cross-section connected to a microwave source (21). One of the reactive species (37) is flowed through the waveguide and pre-ionized, thus, permitting independent control over the activation ...
Tobacco smoke filters comprising a rod of tobacco smoke filtering material, such as cellulose acetate tow including a thread incorporated therein or a tape wrapped therearound, the thread or tape carrying a smoke-modifying agent, such as a flavoring material and methods and apparatus for forming suc ...
Webs which are to be converted into wrappers for filter rod sections, cigars, cigarillos or cigarettes, or the wrappers of such articles, are perforated by one or more laser beams in the machine wherein the articles are produced. The permeability of wrappers can be changed by increasing or reducing ...
