A cervical intervertebral prosthesis includes lower and upper anchoring plates with a prosthesis core arranged between them to create an articulated connection. The anchoring plates are designed to bear with their anchoring plate surfaces on adjacent vertebral bodies. At least one anchoring plate surface has a rib-like projection thereon which can be used to engage in the vertebral body with a form fit. In order to produce a corresponding recess in the vertebral body, an instrument having a handle, a stem, a head part and an excavating element that can be retracted into the head part may be used. This permits considerably improved securing of the cervical intervertebral prosthesis against unintended movement. The medullary canal running along the posterior margin of the vertebral column is in this way protected from damage.

A handheld projector is provided with an image stabilization system that acts to reduce (or even eliminate) unwanted motion of the projected image due to unintended movement of the projector. In certain preferred embodiments, a solid-state motion sensor provides input to an image stabilization system that computes a corrective signal. In embodiments having optical image stabilization, the corrective signal is supplied to a mechanical actuator that moves one or more optical elements within the projector. Other embodiments have electronic image stabilization. In these embodiments, the corrective signal from the image stabilization system is used by the image generator to shift the image so as to compensate for movement of the projector.

A method is provided for image stabilization in an optical instrument (1, 101) with observation optics (3) that have an optical axis (OA) and at least one optical element with adjustable refractive power (7, 7A, 7B, 177), an unintended movement taking place between the observation optics (3) and an observation object (4) along the optical axis (OA). The unintended movement along the optical axis (OA) is determined and on the basis of the movement determined, at least one control variable for the adjustable optical element (7, 7A, 7B, 177) is determined, which represents the refractive power of the optical element with adjustable refractive power (7, 7A, 7B, 177) necessary for optical compensation for the movement along the optical axis (OA). An adjustment of the optical element with adjustable refractive power (7, 7A, 7B, 177) is carried out on the basis of the control variable.

An operation lever lock device reliably prevents unintended movement of a fork without obstructing a forward field of view. The valve input section (22) of a hydraulic control valve (20) disposed below a floor panel (FL) and a corresponding operation lever (10) are coordinated with each other by a link member (60), and a hydraulic control valve (20) is moved by moving the link member (60) in the vertical direction through the operation lever (10). An operation lever lock device is provided with: an engagement member (70) below the link member (60) and a floor panel (FL); and a stopper plate (80). The stopper plate (80) is disposed so as to be capable of moving between an engaged position at which an engagement section (83) engages with the engagement member (70) and a disengaged position at which the engagement section (83) is disengaged from the engagement member (70). When the stopper plate (80) is disposed at the engaged position, the stopper plate (80) prevents the link member (60) from moving in the vertical direction.

A radially expandable trocar, port or cannula system is provided for use in minimally invasive surgeries. The cannula creates a port access with an initial small internal diameter. The passage of thecannula devices is defined by a plurality of elongate rigid members. A number of mechanisms are provided for expanding the passage of the cannula devices, by moving the plurality of elongate rigid members towards a larger radial location, thereby creating a larger internal diameter for the port. The elongate rigid members can be prevented from unintended movement when the system is at the un-expanded state, during expansion and when it is expanded to the desired larger diameter. Example embodiments include methods of preventing gas loss from the tissue that would occur through the gaps createdduring expansion.

The present invention is a simple-to-use IV placement assist device with a base, finger interfaces extending from the base, and mechanical means to engage a needle hub. A catheter advancer is slidably integrated with the base to guide advancement of a catheter linearly along the insertion plane defined by the orientation of the base.

To eliminate or otherwise reduce unintended movement of a probe tip of a probe assembly being held by a probe arm, the probe assembly includes one or more resilient members that compensate for the contraction or expansion of the probe arm in accordance with the coefficient of thermal expansion of the material from which the probe arm is made. Thus, the probe tip can remain in contact with a sample being measured at the desired location on the sample, during an automated full or wide scale temperature range sweep.

A steering apparatus is provided which can suppress unintended movement of a steering wheel when a clutch is engaged. When a power switch is turned off and a steering wheel is steered, a reaction force control circuit makes a reaction force motor to generate a steering reaction force stronger than a normal steering reaction force to give a driver an appropriate feeling of response according to a steering torque. The strong steering reaction force is applied to a steering shaft to suppress steering of the steering wheel. A steering operation control circuit executes steering operation control, that is, control that makes an actual steered angle equal to a target steered angle based on a steering angle, and then a clutch is engaged. The clutch is engaged after confirmation of an immovable state of steered wheels, and thus rotation of the steering wheel unintended by the driver is suppressed.

A consumable product use tracking system includes a consumable product handling apparatus having a first marker is moveable relative to a date indicia, wherein the first marker selectively identifies a distinct date from the date indicia, and a second marker is moveable relative to a time indicia, wherein the second marker identifies a distinct time from the time indicia. A marker positioning mechanism is associated with the first and second markers, the apparatus, or both, for securely holding the markers so as to identify the distinct date and time and prevent accidental or unintended movement of the markers to another date and time. The markers are selectively moved to identify the distinct date and time after each use or for a future use of the consumable product handling apparatus.

Substantially elevated movement sensitivity of a mouse enables improved control and finer manipulation of an object, for example a pointer, displayed on a display device. However, the elevated movement sensitivity also results in unintended movement of the mouse, generated when a button of the mouse is operated, being translated into displacement of the pointer on the display device. An embodiment of the invention describes a method for transducing movement occurring during an interval into signals in response to the button being operated. The signals are for use in manipulating the object. The method is further for comparing properties of the displacement with pre-defined reference properties to determined whether the movement is intended or unintended. The signals are subsequently terminated to impede manipulation of the object when the movement is determined to be unintended to thereby correct the unintended movement.

Unintended movement governor for limiting the movement of a moving object, which unintended movement governor comprises a pulley (1), a part (2), coupling means (5), with which the part (2) is connected to the pulley (1), for rotating the part (2) via the coupling means along with the pulley (1), and means (3) that can be switched into a state limiting the movement of the part (2). When the means (3) are in the state limiting the movement of the part (2) they are arranged to impair the rotation of the part (2) along with the pulley (1) such that relative movement is caused between the part (2) and the pulley (1) if the pulley (1) rotates, and that when the part (2) is in the limited state in terms of its movement it is arranged to stop the rotation of the pulley (1) or at least essentially decelerate the rotation after the part (2) and the pulley (1) have moved a predetermined amount (A, B) with respect to each other. The elevator according to the invention comprises an unintended movement governor as defined in the preceding.
