A notebook computer with a detachable keyboard has an independent keyboard module that connects to the main body of the computer through a conductive line. The keyboard module has a bottom section equipped with at least one support bracket. When in use, the keyboard module may be detached from the main body, and through the support bracket raised to a desired angle to conform to ergonomics so that users may comfortably operate the keyboard without becoming fatigued.

This clamp facilitates the firm tying of ice and roller skates by clamping the two sides of the skate boot and holding them. This makes it easy for children and adults to produce a more uniform tightness while reducing hand fatigue and string-burn. By reducing the friction normally caused by the yanking of strings through the eyelets, string life will be prolonged. An alternate use of this clamp is to facilitate the firm tying of other clothing items with laces. Another alternative use of this clamp is to facilitate the firm tying of other non-clothing items with laces.

The striking member for use with a percussion instrument is a vibration-inducing and flexing variation of a conventional unitary or one-piece drum stick, drum mallet or the like. The striking member includes a stick having opposed first and second ends, and a hollow shell having an opening formed through a lower end thereof. The first end of the stick is adapted for grasping by the user, and the second end is inserted through the opening, into an open interior region of the hollow shell. The hollow shell is secured to the stick, and flexes when striking a surface, such as a drum, for example. An elastic material may further be received within the hollow shell, and may at least partially fill the open interior region thereof in order to provide further elastic properties for the head of the striking member.

An improved hand-held implement is provided with a body having external surfaces that define contours which match and ergonomically engage the surfaces of a user's thumb and fingers when the user grasps the implement, so as to provide a large surface area of contact between the user's hand and the implement. The increased area of contact between the user's hand and the implement, compared to traditional designs, decreases the required level of applied unit area pressure, and also provides for greater control consequently facilitating manipulation of the implement. The exterior of the implement is sufficiently small so that, while in use, the body of the implement does not extend outside or beyond the hand of the user. The cartridge includes a coaxial retention ring device which readily fits into the body of the implement by the resilient engagement of the ring into the coaxial recessed groove in the implement body. The implement is further provided with a spring operated mechanism for extending and retracting the tip from the cartridge. The outer surfaces of the implement, having relatively smooth flat surface, are well-suited for application of art work, logos and graphics for advertising and promotional purposes.

An embodiment in accordance with the present invention provides a tracking system architecture for tracking surgical tools in a surgical field. The system architecture is integrated into a mask placed directly on the face of the patient. The system can combine multiple imaging and range finding technologies for tracking the eye and the surgical instrumentation. The system can be used to generate a three dimensional scene for use during the surgical procedure. Additionally, the system can incorporate a modular design to account for variable anatomy. The system described is for eye surgery applications. However, the system could also be used for other procedures such as cochlear implant or craniotomy.

The quick heat ice cream scoop is an improved heat ice cream scoop that includes a ceramic heating element and an ergonomic grip. The ceramic heating element is built into the ice cream scoop and quickly heats up the ice cream scoop, and conversely shall quickly cool down when turned off. The ice cream scoop is mounted to an ergonomic grip that reduces hand fatigue of the end user while providing a location to store powering means for powering the ceramic heating element.

An improved ergonomic hand-held instrument is provided with a housing having external surfaces defining contours which ergonomically engage surfaces of a user's thumb, index finger and middle finger when the user grasps the instrument, to provide a large surface area of contact between the user's hand and the instrument. The increased area of contact, compared to traditional designs, decreases the required level of applied unit area pressure, and also provides for greater control in manipulating the instrument by a wide range of users. The housing holds a removable cartridge having a working end or tip. The working end may be a pen, pencil, scalpel, knife, stylus, brush or similar tool. The top outer surface of the instrument includes an index finger compression surface for placement of the user's index finger. Base for storage of the instrument and at least one removable cartridge is also disclosed.

Adjustable hand rest attachment for a musical instrument, wherein the hand rest post is constructed to provide multiple adjustments of the position of the hand rest on which the hand or hands of the musical performer rest when playing a musical instrument, such as a bassoon or contrabassoon. The adjustable hand rest attachment incorporates an articulated hand rest post to allow for varying angles of adjustment. The adjustable positioning of the hand rest achievable through adjustment of the articulated and adjustable hand rest post, reduces discomfort for the player and reduces injury with overuse. The adjustments of the hand rest and the hand rest post may then be secured into a fixed position. A bassoon is equipped with a key mechanism that is constructed using a tube that consists of a tenor joint, a boot (also known as a double) joint, a long joint, and a bell joint. A bassoon weighs approximately 8 pounds and is over 4 feet in length so that support of the instrument by the hands while playing without undue discomfort or fatigue is a significant concern. A contrabassoon is equipped with a key mechanism and is constructed using a tube of approximately double the length of the bassoon.
