A connector adapter that can be used to directly connect a peripheral device to a host device. The connector adapter is adjustable so as to allow selective reorientation of the peripheral with respect to the host device. The connector adapter includes a limiting mechanism that restricts the degree to which the adapter can be selectively rotated. In addition, the adapter includes an indexing mechanism that allows the position of the adapter to be locked in predetermined positions. In one embodiment, the connector adapter is partially formed from a compliant material so that the adapter can bend when submitted to an external force, and thereby resist breakage. The connector adapter may also have a physical geometry that provides additional strain relief, such as a plurality of serrations formed on the outer surface. An extension spring can be positioned within the connector adapter so as to return the adapter to substantially its original shape when the external force is removed.

A device for the determination of a plane containing the mechanical axis of the femur includes a mechanical member of articulated and or/sliding elements for the determination and memorization of two positions in space (F1 and F2) of the same point (F) of the knee, freely selected, when the knee is in position P1 and P2, relative to a referential system. These positions are obtained by rotation of the inferior limb from position P1 to position P2, about the centre of the femoral head. The orientation of an omega plan perpendicular to the frontal or sagittal plane containing the centre of the femoral head and the centre of the knee can be materialized by a rod contained in this plane, which rod is fixed perpendicularly and in the middle of the arm having at the ends two localization elements for points F1 and F2.

An electric field driven liquid crystal lens cell including a first substrate and a second substrate arranged opposite each other, a first plurality of split electrodes formed on the first substrate, each of the first plurality of split electrodes corresponding to one of a plurality of lens regions, a second electrode formed over an entire first surface of the second substrate, a voltage source to apply differing voltages to the first and second plurality of split electrodes, a spacer formed between the first substrate and the second substrate, the location of the spacer corresponding to the vertex of the lens when voltages are applied to at least one of the first plurality of split electrodes and the second electrode, and a liquid crystal layer disposed between the first substrate and the second substrate.

A femoral caliper having one or more anatomical referencing members for placement against portions of the femur, such as the anterior cortex and posterior portion of the femoral condyles, to measure the femur for sizing of the femoral component. A reference mark positioning guide of the femoral caliper is connected to the anatomical referencing member and is capable of guiding placement of a reference mark on the femur that facilitates positioning of the femoral component. The femoral caliper includes an adjustment mechanism capable of displacing the reference mark positioning guide relative to the anatomical referencing member. This allows adjustment of the position of the reference mark (and hence the femoral component) on the femur to account for the up or down sizing of the femoral component. Preferably, the adjustment mechanism adjusts the reference mark positioning guide in the anterior-posterior direction to allow balancing of the tightness or laxity of the selected component.

A method, system, and program for allowing callers to adjust in position within a call hold queue are provided. An advancement token earned by a caller is detected at a calling queue. The position of the caller within the calling queue is adjusted, in response to redemption of the advancement token, such that the caller is allowed control over the position within the calling queue by earning advancement tokens. In particular, a caller may earn advancement tokens by participation in competitions or surveys or by redemption of membership points.

A mount for attaching a projection device to an overhead structure includes a device interface operably attachable to the projection device and a device orientation adjustment structure operably coupled with the device interface. The device orientation adjustment structure has structure defining up to three independent axes for adjustment of projector pitch, roll, and yaw. A single selectively adjustable friction element may be provided to enable projector position to be fixed about for any one or all of the independent axes. A gear adjustment mechanism may be provided to enable fine adjustment of projector position. Moreover, any one or all of the independent axes may pass through the projector device, preferably proximate its center of gravity so that it is self balanced on the mount to ease adjustment.

A garment including an adjustable weight support mechanism used to shift the weight and position of objects contained within pockets disposed on the garment is provided. The garment has a number of pockets including a storage pouch releasably attached to the rear of the garment. The support mechanism is attached to the garment and includes a pair of strap assemblies which extend from the shoulders of the garment downwardly towards the bottom of front and rear panels forming the garment. The first strap of each assembly is connected between the shoulder of the garment and the front panel. The second strap assembly is connected between the rear panel and the first strap, and is adjustable in length. When the second strap is pulled to shorten the length of the second strap, the second strap pulls the first strap downwardly and forwardly to pull the shoulders and rear panel of the garment upwardly and move the weight contained in the storage pouch upwardly onto the shoulders of the wearer of the garment, and off of the lower back.

A directional coupler uses non-metallic slotted spacers at the edges of a pair of coupled lines. The spacers are adjustable in their vertical position and thereby provide continuous coupling fine-adjustment. The spatial relationship between the coupled lines is therefore adjustable and does not depend upon extremely tight manufacturing tolerances.
