A pointing device incorporates a biometric sensor at a location such that when operating the pointing device in a normal manner, a user's hand rests naturally in a position to place a finger of the user's hand in proximity to and readable by the biometric sensor. In one embodiment, a computer trackball pointing device includes a fingerprint sensor which is equally well suitable for use by either a right-handed or a left-handed user. Along with positional information from a position sensor and user selection information from at least one user-depressable button, the pointing device also conveys to an attached computer system information associated with the user's identity detected by the fingerprint sensor. Such a pointing device is well suited to both transparent verification as well as continuous verification, for if a user removes his or her hand from the natural position when using the device, the user's fingerprint will no longer be detectable by the fingerprint sensor, and the computer system to which the pointing device is attached can be alerted as to the need to re-authenticate any additional attempts at using the pointing device.

The present invention allows computer users to integrate any annotation, including ink, highlighter, text-based notes and audio, directly into a Web-based document (WBD) displayed by a Web browser. This integration enables others to view the personalized annotated WBD, which retains its original active links and properties, over the Internet without the need for specialized software. Annotations are integrated into WBDs by freezing the WBD, overlaying an image file containing the annotations onto the WBD, and enabling browser events to pass through the image layer. Annotations may also be integrated into WBDs by using component object technology. The present invention collects and organizes annotated WBDs, and provides users with an intuitive Web-based interface for accessing, viewing and searching the annotated WBDs. Users may annotate blank WBDs, effectively converting their Web browsers into online notebooks/ scrapbooks. The present invention also provides users with many novel interface techniques, such as dog-ears and its associated navigation tools, splitting pages, turning pages, selecting and copying various portions of a WBD (including shaking out a copy), and marking menus suited for right-handed or left-handed users.

A reflective impedance element is connected to a port of a composite right/left-handed transmission line, and operates at a predetermined operating frequency so that an impedance when the reflective impedance element is seen from the port becomes a pure imaginary number jB. A reflective impedance component is connected to a port of the composite right/left-handed transmission line, and operates at the predetermined operating frequency so that an impedance when the reflective impedance element is seen from the port becomes −jB.

This application relates to slot antenna devices based on Composite Right and Left Handed (CRLH) metamaterial (MTM) structures.

High-frequency couplers and coupling techniques are described utilizing artificial composite right/left-handed transmission line (CRLH-TL). Three specific forms of couplers are described; (1) a coupled-line backward coupler is described with arbitrary tight/loose coupling and broad bandwidth; (2) a compact enhanced-bandwidth hybrid ring coupler is described with increased bandwidth and decreased size; and (3) a dual-band branch-line coupler that is not limited to a harmonic relation between the bands. These variations are preferably implemented in a microstrip fabrication process and may use lumped-element components. The couplers and coupling techniques are directed at increasing the utility while decreasing the size of high-frequency couplers, and are suitable for use with separate coupler or couplers integrated within integrated devices.

Flexible metamaterials and three-dimensional metamaterials operable in the terahertz range are disclosed. Methods are disclosed for fabricating terahertz response metamaterials using microfluidic-jetted techniques. Layers of material including substrate and deposited material are stacked to form three dimensional bulk metamaterials. The fabricated metamaterials act as left-handed metamaterials in the range 0.1 to 3.0 THz.

A friction-stir welding probe tip is disclosed which has right-handed threads on one portion of the probe and left-handed threads on another portion of the probe such that weld material is drawn to the middle of the weld as the friction-stir welding probe is rotated and passed along the joint region of the pieces to be joined. This probe tip is also fitted with a shoulder region for gripping by a rotation means.

A cervical spine brace and traction device incorporates a forwardly open head and jaw brace which is adjustably supported vertically above a forwardly collar member. The brace and the collar member have cooperating lateral wall sections having mating arcuate surfaces that are juxtaposed and which include interengaging means that assure they remain precisely angularly aligned with each other while the vertical spacing between them is being changed. Support of the brace and adjustment is by pairs of laterally extending brackets which interconnect with rotatable rod mechanisms that carry coaxial right-handed and left-handed lead screw surfaces. A miter gear affixed to each rod in a central location mates with a cooperative miter gear affixed to a horizontal shaft that carries a starwheel at one end which permits smooth and accurate patient adjustment.

An ambidextrous mouse is disclosed. The ambidextrous mouse is configured for both left and right handed use. The mouse may include right handed buttons on the front side of the mouse and left handed buttons on the back side of the mouse. The user may change the handedness of the mouse by rotating the mouse about a vertical axis of the mouse such that the left hand can use the left hand buttons and the right hand can use the right hand buttons. The mouse may include a handedness selection system for configuring the mouse for right handed or left handed use even though the mouse has the capability for both right and left hands.

A monitor supporting and rotating structure, by which a monitor is capable of being erected and rotated. The monitor supporting and rotating structure includes a supporting stand and a rotary member pivotally attached to the top of the supporting stand. The supporting stand is capable of being propped outward. It is by propping the supporting stand away from the display that the display is oriented and erected above a plane. Further, the rotary member enables the display to perform left-handed, right-handed, forward, or backward rotations. The monitor supporting and rotating structure both facilitates the mobility of the monitor and its efficient usage of space.

An intubation laryngoscope having reusable and disposable blades adapted for both right and left-handed operation, an illumination system mounted on the laryngoscope handle, and an improved fastening appliance for detachable connection of the blades to the laryngoscope handle.

An aspect of the present invention provides a lens-interchangeable camera which has operability equal to a right-handed user and a left-handed user without necessity of any addition of extra members and without sacrificing a design for a smaller size. Since a camera according to the present invention does not need any extra members, a user-friendly camera which eliminates any disadvantage for a use by left-handed persons at a high level that any conventional cameras have not yet achieved can be achieved. Also, since a camera body can be disposed on a left side as needed even for a right-handed user and the right-handed user can operate the camera body only with his/her left hand, this form is convenient when the user picks up images while the user is operating another apparatus with his/her right hand.

A firearm, in particular a self-loading small-caliber rifle, having a barrel, a breech housing having a breech held in it, with the breech and/or the breech housing being designed such that the firearm can be changed from a first assembled arrangement, which is suitable for right-handed gunners, to a second assembled arrangement which is suitable for left-handed gunners, with the firearm preferably being in the form of a rifle of the Bullpup type.

A protective carrier to hold a loaded spare magazine in a position of readiness for immediate insertion into operative engagement with a firearm. A latch release mechanism is operable wholly independent of the operation of the magazine release mechanism of the firearm, so that a spare magazine will remain in the protective carrier despite release of a magazine from the firearm. The spare magazine can be released from the carrier by pressing a latch release lever located for convenient use by either a left-handed or a right-handed rifleman.
