摘要:
An integrated interferometric gyroscope and accelerometer device. An example device includes a cantilever beam, a package having a post connected to one end of the beam, a piezoresistor driver, a piezoresistor sensor, and a semiconductor interferometric optical gyro. The piezoresistor driver is incorporated within the beam at a first area proximate to the post. The driver electro-thermally resonates the beam. The piezoresistor sensor is incorporated within the beam at the first area. The sensor piezoresitively senses a signal that relates to an acceleration force out-of-plane of the beam. The semiconductor interferometric optical gyro is also incorporated within the beam at a second area of the beam. The gyro senses rotational motion about an axis approximately equivalent to the acceleration force out-of-plane of the beam. The gyro includes a waveguide, a laser source and a light detector. The beam is formed from a semiconductor substrate.

Techniques to modify a document using a latent transfer surface are described. An apparatus may comprise a document editing subsystem comprising a transfer surface creation module operative to embed a latent transfer surface in the document. A transfer control module may be communicatively coupled to the transfer surface creation module. The transfer control module may be operative to receive a transfer request to transfer media content for the document, and transfer the media content using the latent transfer surface in response to the transfer request. Other embodiments are described and claimed.

A method of operating a glucose test meter is provided. The method can be achieved by storing a plurality of glucose readings to a first memory of the test meter, each of the glucose readings having a time stamp and an order index, the time stamp comprising a date and a time when the glucose reading was performed, the order index indicating an order in which the plurality of glucose readings was saved to the first memory; determining whether successively saved glucose readings have time stamps in chronological order consistent with the order index; and indicating that the date and the time setting in the test meter is incorrect if there are successively saved glucose readings having time stamps inconsistent with the order index.
摘要:
A lightweight information user interface is provided for displaying information about a focused-on (e.g., mouse-over) text item, data item or other object in an electronic document that minimizes interruption of workflow with the electronic document. Upon focus on a word or other object in an electronic document a quick look-up function may be invoked for retrieving information from a local or remote information source about the focused-on item. Retrieved information, for example, translations, dictionary definitions and research information, is displayed in close proximity to the focused-on item in a lightweight information user interface. Information may be displayed according to a variety of media types including text, audio, video, pictures, bitmap images, etc.
摘要:
A mobile CT imaging system comprising: a frame having a center opening, the frame being formed with a uni-body construction; and a CT imaging unit mounted to the frame, wherein the CT imaging unit is adapted to scan anatomical objects located within the center opening and generate images of the same, wherein the CT imaging unit comprises: a rotatable drum assembly rotatably mounted to the frame, concentric with the center opening, wherein at least one bearing is disposed between the rotatable drum assembly and the frame, and further wherein one race of the bearing is formed by a surface of the rotatable drum assembly and the other race of the bearing is formed by a surface of the frame; an X-ray tube mounted on the rotatable drum assembly and configured to emit an X-ray beam; and an X-ray detector mounted on the rotatable drum assembly in alignment with the X-ray beam; and a transport mechanism mounted to the frame, wherein the transport mechanism comprises a fine movement mechanism for moving the CT imaging unit precisely, relative to the patient, during scanning.
摘要:
A graphical user interface for use with a multi-media system, such as those found in vehicles, that includes a rotary knob, a graphics control circuit and a graphics display with a graphical depiction of a portion of the rotary knob. The graphical depiction includes a menu wheel and at least two menu items located near its periphery, where each of the menu items corresponds with a device, system or network (i.e.—satellite radio, navigation system, DVD player, video game system, wireless internet, etc.) with which the multi-media system can interact. Furthermore, rotation of the rotary knob by a user causes a corresponding graphical movement of the menu items along a periphery of the menu wheel.
摘要:
A system for cooling an X-ray tube in a CT machine, wherein the X-ray tube is of the type comprising a rear cylindrical portion, a front cylindrical portion, an annular face formed at the intersection of the rear cylindrical portion and the front cylindrical portion, and an emitter opening formed in the front cylindrical portion for emitting X-rays from the X-ray tube, the system comprising: a heat sink for drawing heat away from the X-ray tube, the heat sink comprising an annular body having an axial opening, and a window extending radially through the annular body, the heat sink being configured to receive the front cylindrical portion of the X-ray tube within the axial opening of the heat sink, with the emitter opening of the X-ray tube being aligned with the heat sink window; and a collimator connected to the heat sink and adapted to collimate the X-rays emitted by the X-ray tube and “focus” those X-rays on an X-ray detector, the collimator comprising a collimator opening, with the collimator being connected to the heat sink such that the collimator opening is aligned with the heat sink window and the emitter opening of the X-ray tube; the heat sink body being formed out of the same material as the emitter of the X-ray tube, such that the emitter opening of the X-ray tube will remain aligned with both the heat sink window and the collimator opening even when the emitter of the X-ray tube undergoes thermal expansion.
摘要:
A piston ventilator is disclosed herein which uniquely includes an oxygen blending module which supplies oxygen enhancement for aiding patients requiring respiratory treatment. The oxygen blending module supplies a preselected enrichment of oxygen to a piston and cylinder assembly wherein the amount of oxygen permitted to flow therein is continuously monitored and controlled according to the volume above the piston in the cylinder as calculated by a controller. The oxygen blending module includes a flow sensor which monitors the flow of supplemental oxygen into the piston and cylinder assembly, and further includes a primary oxygen control valve which restricts the flow of oxygen through the flow sensor to the piston and cylinder assembly depending on the difference between the calculated desired amount of oxygen and the target amount of oxygen provided to the controller.
