Embodiments of a stand are provided with continuous adjustability within a range of travel. In one embodiment, a stand includes a movement mechanism adapted to allow a tray to move along a range of travel relative to a stand base. The movement mechanism is in some embodiments further adapted to position the tray at an infinite number of locations along the range of travel.

Embodiments include a balance mechanism having a first cam and a second cam configured to convert a variable force exerted by the energy storage member into a substantially constant force applied to a mounting portion. The balance mechanism may be useful for balancing forces such that a user can set the height of an electronic display and/or other equipment attached to the balance mechanism at a number of heights within the range of travel allowed by the mechanism. Lift mechanisms, display positioning apparatuses, and height adjustable desks incorporating a multi-cam balance mechanism are also provided. A method of positioning a display is also provided.

Embodiments include an apparatus for positioning items such as an electronic display, a keyboard, and/or a work surface. The apparatus can be attached proximate an edge of a generally planar support member to provide a multi-position workstation. In some cases the apparatus includes a display mount coupled to a support column and configured to support an electronic display and a keyboard. The support column may be movable with respect to support member between a sitting position and a standing position. Methods for positioning an electronic display and a keyboard are also included.

摘要:
The intervertebral implant is in the form of a three-dimensional structure (10) comprising (a) a top side (1) and an underside (2) which are designed to rest against the end plates of two adjacent vertebras, (b) a left side face (3) and a right side face (4), (c) a front face (5) and a rear face (6), (d) a horizontal center plane situated between the top side (1) and the underside (2), (e) a vertical center plane (8) situated between the left side face (3) and the right side face (8) and (f) a plurality of boreholes (9) passing through the implant structure (10) that are designed to receive longitudinal affixation elements (20), the axes (19) of said elements intersecting the horizontal center plane (7). At least one of the boreholes (9) is designed in a manner that the affixation element (10) received in it can be rigidly connected to the intervertebral implant. Said connection is implemented using a thread or by matching conical surfaces.

A system for evacuating a reactor chamber includes a main evacuation line connected at one end thereof to the reactor chamber and at another end thereof to a means for creating a partial vacuum. A valve in the main evacuation line divides the line into a chamber side and a vacuum side. A second line is connected at one end to the vacuum side of the main evacuation line and at another end to a fluid supply source. As the valve in the main evacuation line is opened, fluid is supplied through the second line to the main evacuation line to prevent rapid, turbulence-inducing pressure drops in the reactor chamber.
摘要:
A method of adaptively predicting blood-glucose level by collecting biometric and activity data with a user portable device utilizes a portable computing device carried by a user to collect movement data and biometric data about and from the user. Collected data is processed by a blood glucose prediction formula generation algorithm in order to produce multiple blood glucose level prediction formulas. Based on the activity level measured by the device, a corresponding blood glucose prediction formula is used to predict blood glucose levels for a certain period of time. The prediction formulas recursively provide feedback and change for successive iterations and new formulas are generated as new data is collected.
摘要:
A display positioning apparatus is provided for lifting, supporting, and/or positioning a load, such as a display. The apparatus includes a base and a lift arm adapted to couple to a display, the lift arm pivotally coupled to the base providing a range of travel. A balance mechanism is operatively coupled to the lift arm and the base to counterbalance the lift arm and display. In some cases the balance mechanism includes a torquing spring member to counterbalance the lift arm and an attached display along the range of travel.
