摘要:
Disclosed herein are methods and apparatuses for the transmission of audio information from a bone-conduction headset to a user. The bone-conduction headset may be mounted on a glasses-style support structure. The bone-conduction transducer may be mounted near where the glasses-style support structure approach a wearer's ears. In one embodiment, an apparatus has a bone-conduction transducer with a diaphragm configured to vibrate based on a magnetic field. The magnetic field being based off an applied electric field. The apparatus may also have an anvil coupled to the diaphragm. The anvil may be configured to conduct the vibration from the bone-conduction transducer. Additionally, the anvil may be anvil may include at least one component configured to change properties to enable the bone-conduction headset to couple to the head of a user with greater than a threshold amount of force.
摘要:
A method of printing spots with high spot placement accuracy using print heads with random/unevenly spaced ejector locations and coarse alignment of the multiple print heads. This is performed by accurately determining the spot positions from all the print heads using a vision system and printing at high addressability. The spot placement accuracy will be determined by the addressability as long as the ejected drop position is reproducible and other system errors are negligible.
摘要:
An electronic apparatus, e.g., a lap top computer, has an enclosure which on its inner surface is coated with a phase-change material, e.g., in micro encapsulated form, preferably mixed with paint which is used to coat the inner surface of the enclosure. The phase change material absorbs heat generated by components in the electronic apparatus and maintains the components in the apparatus at a reasonable temperature.
摘要:
A hybrid pin-fin micro heat pipe heat sink consists of a plurality of heat pipes secured to a base. The heat pipes have a generally hollow cross-section which transitions from a first cross-sectional shape (e.g., circular) to a second cross-sectional shape (e.g., triangular). A heat transfer medium (e.g., saturated steam) is sealed within the heat pipes. Cooling plates may be disposed over the base with the heat pipes in physical contact with and passing through the cooling plates. The method of manufacturing the heat pipes consists of passing a heat transfer medium through a pipe section having a first cross-sectional shape while transitioning to a second cross-sectional shape (e.g., by way of a rolling die press), then crimping the ends closed to seal the heat transfer medium therein.

Disclosed is a semiconductor package and method in which a semiconductor chip is mounted within the opening of a lead frame by bonding wires extending between the active front side of the chip and bonding pads of the lead frame, and the lead frame/chip assembly is encased within a plastic molded body, with the inactive back side of the chip exposed and facing outside the package.

摘要:
An apparatus for positioning an object, for example, a solar energy capture device, can include a frame, the object, a joint, and at least two linear actuators. The joint connects the object to the frame and allows the object to rotate relative to the frame. The first and second linear actuators are coupled to the object. When the first and second actuators are actuated in combination, the object rotates about a pitch axis. When the first and second actuators are actuated differentially, the object rotates about a roll axis.
