Abstract: A blood collection tube includes a body, a chamber, a vacuum port, and a cap. The cap includes a first septum, a first conduit having an inlet extending from the first septum and an outlet in fluid communication with the chamber, a second septum, and a second conduit extending radially from the second septum to the first conduit. When a fluid source is fluidically connected to the first septum or the second septum, and a vacuum is applied at the port, the vacuum draws fluid from the fluid source, through the first or second septum, and into the first conduit. A blood collection device includes a vacuum pump and a plurality of reservoirs containing concentrated blood additives. The tube and device form a system for collecting blood samples at low vacuum to tubes previously stored at atmospheric pressure. The system prevents risk of misidentification, mislabeling, or incorrect ordering of tubes.

Abstract: A graphical user interface for a computer includes a dial control. The control can be implemented, for example, as a touch-based, pointer-based, pen-based and/or keyboard-based mechanism. The dial control is intended for manipulating a large range of values, such as a menu of items from which a user makes a selection, or a range of continuous or discrete values. A dial control can replace other control types such as a slider, drop down menu or text field. The graphical elements of the dial control include one or more displayed rings and a handle for each ring. Inside the ring, or in another area adjacent the ring, a value can be displayed. The ring can be manipulated by the user to change the value selected by the dial control. In the case of multiple rings, each ring can be manipulated independently.

Abstract: A pipe handling assembly includes a pipe engaging apparatus having a pipe gripping mechanism connectable to a top drive such that the top drive transmits rotational movement and axial movement to the pipe gripping mechanism. A pipe handling device is mounted onto the pipe engaging apparatus, the pipe handling device including a link hanger mounted on the pipe engaging apparatus. A link arm has a first end pivotally connectable to the link hanger and an outboard end selected to carry a pipe into a position to be gripped by the pipe engaging apparatus. A bearing isolates rotational movement to the pipe gripping mechanism from the link hanger. A connection rigidly connects the link hanger to the pipe engaging apparatus during operation of the pipe handling assembly. The connection is selected to substantially prevent the link hanger from rotating with the pipe gripping mechanism should the bearing seize.

Abstract: Disclosed herein is a Invention which communicates physical assistance to steering a conventional two wheel or three wheel motorcycle. As it can be used to fine tune a two wheel motorcycle. The invention when applied to a three wheel motorcycle, or also referred to as a tricycle, quite profoundly eases the steering input necessary by the operator. In a three wheel application, steering becomes harder proportionally as the vehicle is turned from straight a head to its maximum turning angle, right or left. This invention can be adjusted to all but eliminate, the input forces applied by the operator proportionately relevant to steering angle. Ease of installation and steering assist adjust ability plus ease of manufacture are also note worthy.

Abstract: A radiation sensor utilizing a single crystal semiconductor pyro-optical film to modulate a photonic carrier beam with energy in excess of the bandgap of the semiconductor for the purpose of detecting a first source of radiation. Specific implementations described here include a thin film of single crystal semiconductor made part of a suspended microplatform thermally isolated above an underlying substrate. The first source of low level radiation incident upon the microplatform and partially absorbed therein causes an incremental heating of the pyro-optical film. A second source of radiation comprised of a photonic carrier beam is incident on said microplatform and exits by reflectivity means or transmission means and is modulated by the pyro-optical effect with incremental heating of the platform and film. A detector or array of detectors monitors the intensity of the photonic carrier beam exiting the microplatform and thereby provides a sensitive means of monitoring the amplitude of the low level radiation.

Abstract: A thermal sensor or sensor array for detecting including imaging of low level radiation. The sensor utilizes a thin film of pyro-optical material to modulate the reflectivity and/or transmission of a photonic carrier beam. The photonic carrier beam is modulated by the temperature of the pyro-optical film and detected by typically a silicon detector. A slight increase in the temperature of the pyro-optical film due to absorbed low level radiation causes a corresponding change in the electrical resistance of heaters within each pixel of the thermal sensor array. An external fixed amplitude voltage or current source provides power to increase the temperature of the pyro-optical film beyond the heating caused by the absorption of low level radiation alone. This thermal amplification effect provides a radiation sensor with electro-thermal signal gain.

Abstract: This invention is a micromachined sensor pixel structure that can be fabricated either as a discrete sensor or in array form with application to thermal sensing of radiation receive from various wavelength emitters. The transmissivity of a thermally-isolated microplatform is a sensitive function of temperature. This transmissivity is modulated by incident radiation from sources including infrared sources. The transmissivity of a micromachined structure is interrogated by means of an optical carrier. Readout is obtained by means of conventional silicon optical sensors or imagers. A multiplicity of micromachined pixels can be tailored for specific wavelengths permitting the array to operate as a multispectral imager with windows ranging from ultraviolet to millimeter wavelengths.

Abstract: A process for producing a multilayered substrate. In a first step, an adhesive layer is applied to a surface of a support substrate. Then a device substrate is placed into contact with the adhesive surface. Then the adhesive is cured. Then the device substrate is thinned. The device substrate has a hydrogen trap layer inside. The trap layer is formed by ion implantation through a face surface of the device substrate. The adhesive is chosen from compounds that release hydrogen upon curing. Thinning of the device substrate is performed by cleavage along a fragile layer of hydrogen microbubbles. The microbubble layer is formed through gettering of hydrogen released from the adhesive layer upon curing onto the trap layer and evolving the trapped hydrogen into the microbubbles. The substrates are preferably silicon single crystalline wafers and the adhesive is preferably hydrogen-silsesquioxane.
