摘要:
A method for magnetic resonance (MR) imaging or spectroscopy on a MR scanner to detect tissue physiological parameters in one or more tissue areas in a human or non-human subject includes administering to the subject a contrast enhancing physiologically tolerable amount of a sugar that is non-labeled, subjecting the subject to an MR procedure capable of generating MR signals encoding at least one tissue area in the subject in which the sugar either passes or is taken up, detecting a temporal variation in the MR signals in the at least one tissue area after the administering the sugar, determining at least one tissue-related parameter from the temporal variation, and ascertaining whether the at least one tissue-related parameter is abnormal.

A vaginal speculum apparatus includes a portable illumination assembly that is releasably attached to one of the upper blade and lower blade of a disposable vaginal speculum. The portable illumination assembly is defined by a housing that retains at least one LED and a portable power supply. The portable illumination assembly can be energized by an externally accessible member after the illuminator has been attached to the speculum.

A setup and calibration unit for a barrier operator is operable to communicate with the operator's own controller. The calibration unit includes a control circuit connected to a visual display and to a set of switches controlled by switch actuators for placing the operator controller in a controller run mode or calibration mode, scrolling through selected actions displayed on the display in one direction or the other, a set/clear function and display backlighting for user interaction with the setup and calibration unit. The setup and calibration unit is particularly adapted for use with upward acting sectional and roll-up doors and other types of barriers movable between open and closed positions by motorized operators. The calibration unit may be operably connected to the operator controller via hard wiring, a radio frequency link or an infrared or visible light transmission link.

A vaginal speculum includes an upper blade member and a lower blade member that is movably connected with respect to the upper blade. The lower blade member includes an integrated handle portion having a receiving cavity configured for interchangeably receiving one of a first illumination assembly and a substantially different second illumination assembly. The first illumination assembly differs from the second illumination assembly by at least one structural and/or functional aspect, such as the form of power supply, the type of light source and physical size of the assembly housing.
摘要:
An articulation mechanism for a vaginal speculum enables selective relative movement between an upper blade member and a lower blade member to affect vertical and angular spacing. The mechanism selectively enables quiet or clicking articulation according to at least one version.

A control unit for a moveable barrier, such as a garage door, includes a microcontroller connected to a motor speed detector, motor current sensor or a sensor for determining forces exerted on or by the barrier. A user interface includes user actuatable switches for setting a first maximum force value to be exerted on or by the barrier when moving in one direction and the microcontroller automatically sets the value of a second maximum force to be exerted on or by the barrier when moving in the opposite direction. The second force value may be based on the force value set by the user or the second force value may be a preset value. Both force limits may be automatically set as a function of a maximum force exerted on said barrier during movement thereof, during a force learning operation.

A garage door opener remote controller unit is mountable on the handlebar of a motorcycle or other handlebar steered vehicle and includes a radio frequency transmitter and a push button actuator for sending a door control signal. The controller unit includes a housing and opposed mounting parts for mounting the controller unit on a handlebar assembly. The controller unit is mounted on a handlebar assembly by screw type fasteners which secure the controller unit housing and mounting parts in assembly. At least one of the mounting parts may include a recess or channel for training vehicle control cables and electrical conductors therethrough and along the handlebar.
