Abstract:
A structure includes a substrate having a plurality of balls, a semiconductor chip, and an interposer electrically connecting the substrate and the semiconductor chip. The interposer includes a first side, a second side opposite the first side, at least one first exclusion zone extending through the interposer above each ball of the plurality of balls, at least one active through via extending from the first side of the interposer to the second side of the interposer, wherein the at least one active through via is formed outside the at least one first exclusion zone and wherein no active through vias are formed within the at least one first exclusion zone, and at least one dummy through via extending from the first side of the interposer to the second side of the interposer, wherein the at least one dummy through via is formed within the at least one first exclusion zone.
Abstract:
An error detection method for a computer system includes the steps of: enabling an error-detecting computer to communicate with a keyboard controller of a computer-under-test through a communication interface; enabling the error-detecting computer to issue an error detection command to the keyboard controller that causes the keyboard controller to issue a request command to the basic input/output system (BIOS) of the computer-under-test; enabling the BIOS, in response to the request command, to access the keyboard controller and determine hardware status information that is being requested from the error detection command, and subsequently, to obtain the hardware status information of the computer-under-test, and to transmit the hardware status information to the keyboard controller; and enabling the keyboard controller to transmit the hardware status information received thereby to the error-detecting computer through the communication interface.
Abstract:
A hair dyeing process which utilizes a hair dye in combination with a heat application means. By applying heat to a person's head, immediately after the dye has been applied, the hair can be quickly and efficiently dyed and hair damage is minimized. The heat application means (12) is disclosed in five designs: the first utilizes a conventional, hand-held, hot-air blower (14) in combination with a plastic head cap (18) such as a shower cap (20); the second utilizes the plastic head cap (16) having attached a light flexible hose (24) that is connected to a heat source (26); the third consists of a hot, moistened towel (32); the fourth consists of a corded, electric heating pad (40); the fifth consists of a cordless heating pad (42) that has inserted a multiplicity of heat absorbing elements (50). When the pad (42) is heated in a microwave oven the elements (50) allow the pad (42) to retain heat for an extended period of time.

Abstract:
A color temperature tunable white light emitting device is provided, including a substrate with an ultraviolet light emitting diode, a purple light emitting diode, and a blue light emitting diode provided over the substrate. The UV LED, the purple LED and the blue LED are coated with a phosphor layer. An omnidirectional reflector is disposed over the phosphor layer. A medium layer is disposed between the omni-directional reflector and the phosphor layer. A transparent substrate is disposed over the omnidirectional reflector and an optical diffuser is disposed over the transparent substrate.
