摘要:
A tile positioning device for height adjusting a tile located on a roof hip or ridge joint, each tile having upper and lower faces. The device comprises two opposing longitudinal spaced apart side members arranged for straddling a roof hip or ridge joint, means for maintaining the longitudinal side members in a substantially parallel configuration, and at least one tile-pressing element mounted between the longitudinal side members. The or each tile-pressing element being arranged to act upon the upper face of a tile located between the longitudinal side members, so as to height position the tile relative to the device.

A method for interfacing a customer with a call center. Information obtained from a Radio Frequency Identification (RFID) tag is transmitted to the call center to provide additional information about the customer and allow the session to be accurately routed within the call center. The call center may be accessed by telephone, computer, or other type of customer premises equipment over a voice or data network. The RFID tag may be an identification tag provided to the customer for access to the call center or may be a tag associated with the customer and not specific to the call center. The call center may route calls based on routing information contained in the RFID tag information, customer identity and previous sessions with that customer, personal and demographic information and statistical support records for other sessions involving customers with similar personal and demographic information, and according to agent statistical support records.

Described is a process for forming an LED structure using a laser lift-off process to remove the growth substrate (e.g., sapphire) after the LED die is bonded to a submount. The underside of the LED die has formed on it anode and cathode electrodes that are substantially in the same plane, where the electrodes cover at least 85% of the back surface of the LED structure. The submount has a corresponding layout of anode and cathode electrodes substantially in the same plane. The LED die electrodes and submount electrodes are ultrasonically welded together such that virtually the entire surface of the LED die is supported by the electrodes and submount. Other bonding techniques may also be used. No underfill is used. The growth substrate, forming the top of the LED structure, is then removed from the LED layers using a laser lift-off process. The extremely high pressures created during the laser lift-off process do not damage the LED layers due to the large area support of the LED layers by the electrodes and submount.

摘要:
LED epitaxial layers (n-type, p-type, and active layers) are grown on a substrate. For each die, the n and p layers are electrically bonded to a package substrate that extends beyond the boundaries of the LED die such that the LED layers are between the package substrate and the growth substrate. The package substrate provides electrical contacts and conductors leading to solderable package connections. The growth substrate is then removed. Because the delicate LED layers were bonded to the package substrate while attached to the growth substrate, no intermediate support substrate for the LED layers is needed. The relatively thick LED epitaxial layer that was adjacent the removed growth substrate is then thinned and its top surface processed to incorporate light extraction features. There is very little absorption of light by the thinned epitaxial layer, there is high thermal conductivity to the package because the LED layers are directly bonded to the package substrate without any support substrate therebetween, and there is little electrical resistance between the package and the LED layers so efficiency (light output vs. power input) is high. The light extraction features of the LED layer further improves efficiency.
摘要:
Devices and techniques for fabricating InAlGaN light-emitting devices are described that result from the removal of light-emitting layers from the sapphire growth substrate. In several embodiments, techniques for fabricating a vertical InAlGaN light-emitting diode structure that result in improved performance and or cost-effectiveness are described. Furthermore, metal bonding, substrate liftoff, and a novel RIE device separation technique are employed to efficiently produce vertical GaN LEDs on a substrate chosen for its thermal conductivity and ease of fabrication.

A low pressure secondary regulator for gaseous fuels for industrial engines that are configured to function on gaseous fuels primarily on propane or natural gas. The GFR (Gaseous Fuel Regulator) is designed to receive gaseous fuel at low pressure (6 oz. or 11 w.c.) and 1. Govern the fuel requirements to the engine, 2. Seal off fuel supply when engine is not in operation. The inventive device includes: Valve Seat Assembly, Control Lever, Magnetic Sensitivity Control, Maximum Fuel Limit Set Screw, and Diaphragm. The valve seat assembly consists of a tapered valve seat and plunger with o-ring. The control lever is long and narrow with one 90 deg. bend. The magnetic sensitivity control involves the use of two magnets. The fuel limit set screw is fabricated from threaded rod. The diaphragm consists of a thin silicon liner with a rigid center and a spring clip.
