Abstract: The present invention is a continuation-in-part of the inventor's prior invention (USPTO application Ser. No. 11/277,502 filed on 26 Mar. 2006), the added feature being a “Grand Staff reference marking” added to a row of the “staff of gray and white pitch stripes” of the prior invention, the said marking comprising one or more set of Grand Staff of five lines, the Grand Staff clef or clefs, with each Grand Staff line pointing or connected to a corresponding correct “white pitch stripe”. Such “Grand Staff reference marking” feature enables the precise identification of the pitch stripes relative to their corresponding keys on the piano keyboard, and in terms of pitch names commonly used by students of music theories. The pitch names of all other pitch stripes can be easily derived from its physical location in relation to those pitch stripes connected to or pointed to by the lines of the “Grand Staff reference marking”.

Abstract: A heat-dissipating structure for a LED lamp includes a heat-dissipating base, a heat-dissipating body and a plurality of heat pipes. The heat-dissipating body has an outer cylinder formed into a hollow cylinder. The inside surface of the outer cylinder is provided with a plurality of accommodating grooves.

Abstract: A multiple-set heat-dissipating structure for a LED lamp for performing the heat dissipation of the LED set includes a heat-conducting base, a plurality of heat pipes and a plurality of heat-dissipating bodies. On end face of the heat-conducting base is used for adhering to and contacting with the LED set. Each heat pipe has a heat-absorbing end and a heat-releasing end, respectively. The heat-absorbing end is connected to the other end face of the heat-conducting base. Each heat-dissipating body has a hollow cylinder. The outer periphery of the cylinder is formed with a plurality of radial heat-dissipating pieces and is connected on the heat-releasing end of each heat pipe. By dispersing each heat pipe and heat-dissipating body, the heat generated by the operation of the LED set can be conducted and dissipated by each heat pipe and heat-dissipating body at multiple points. In this way, the LED set can be continuously operated under a suitable working temperature and thus its life can be elongated.

Abstract: A hinge assembly attaches a cover pivotally to a base of an electronic device and has a pivoting leaf and a stationary leaf. The pivoting leaf is mounted in the cover and has a shaft. The stationary leaf is mounted rotatably around the pivoting leaf, is mounted in the base to allow the cover to pivot relative to the base and has a barrel. The barrel is tightly mounted rotatably around the shaft and has a gudgeon and a slit. The gudgeon is formed coaxially through the barrel. The slit is formed longitudinally through the barrel and communicates with the gudgeon and allows the barrel to expand to fit the shaft. Having the barrel with the slit reduces the size of the hinge assembly so the hinge assembly allows electronic devices to be smaller and thinner.

Abstract: A hinge assembly attaches a cover pivotally to a base of an electronic device and has a stationary leaf, a bushing and a pivoting leaf. The stationary leaf is attached to the base and has a barrel and at least one slot. Each slot is formed in the barrel. The bushing is mounted in the barrel and has two end edges and at least one tab. Each tab is formed from the bushing near the corresponding end edge and is mounted in the corresponding slot. The pivoting leaf is mounted rotatably in the bushing and attaches to the cover. Consequently, the hinge has a small bushing and uses less material so reducing the size and weight of the hinge assembly, and the same of the electronic device.

Abstract: A hinge assembly attaches a cover pivotally to a base of an electronic device such as a notebook computer and has a base bracket, a pintle and a cover bracket. The base bracket is attached to the base and has a gudgeon. The pintle is mounted securely in the gudgeon in the base bracket. The cover bracket is mounted tightly and rotatably around the pintle and securely on the cover of the electronic device, allows the cover to pivot on the base and has a through ring and a pivoting gudgeon. The through ring is mounted tightly around the pintle and has an open slot to prevent the through ring and the pintle from wearing. The pivoting gudgeon is slightly narrower than the through ring, fastens the pintle to position the cover and has an open slot to prevent the pivoting gudgeon and the pintle from wearing.

Abstract: A transversely movable hinge has a central bracket and two tilt hinge assemblies and is mounted between a cover and a base of an electronic device to allow the cover to pivot and rotate relative to the base. Each tilt hinge assembly has a pivoting leaf with a mounting segment, a torque washer and a biasing assembly. The torque washer is rotated relative to the mounting segment and has at least one protrusion. The biasing assembly presses the torque washer so the protrusion rubs against the mounting segment to provide a larger force to hold the cover at any visual angle. Then even if the resilient force of the biasing assembly is reduced to allow the cover to be easily moved transversely relative to the base, the hinge can still provide enough holding force.

Abstract: A pivotal-axis changing hinge has a stationary leaf, a pivoting leaf, a pintle assembly and a cam. The pivoting leaf and stationary leaf are respectively connected securely to a cover having a rear edge and a keyway and a base having an elongated gudgeon. A parabolic edge is formed at an edge near the elongated gudgeon. The pintle assembly is mounted through the keyway and pivotally through the elongated gudgeon to allow the leaves to pivot along a pivotal axis of the pintle assembly. The cam is mounted on the pintle assembly, rotates simultaneously with the pintle assembly and has a protrusion mounted slidably on the parabolic edge to move the pintle assembly and the cover perpendicularly away from the base when the cover is pivoting. Consequently, the proximal edge of the cover is kept from colliding with the base and the rotating angle of the cover is expanded.

Abstract: An improved musical notation system, which uses a staff patterned upon the standard piano keyboard. It replaces the Grand Staff's system of lines and spaces with a system of “pitch stripes” of two colors arranged in the same pattern as the black and white keys of the standard piano keyboard. Music scores, especially those for keyboard music, produced with the art are significantly easier to understand and sight-read. The art further incorporates positional numerical music notes to marry positional notation and numerical notation of music in the same musical score. The art further facilitates a method by which music scores of the same music in different keys can be obtained easily by moving all markings and notes collectively up or down the staff.
