Abstract:

The invention includes a coil support assembly having an insulator interfacing a surface of a shield disposed within a processing chamber. The insulator has an extension which extends through the shield. A second insulator is disposed between the shield and a coil and contacts a protrusion extending from the coil. A fastener is disposed through the first insulator and extends through the second insulator and into the protrusion. The fastener is electrically isolated from the shield by the first insulator. The invention includes coil assemblies containing the described coil support configuration. The invention further includes a method of supporting a coil within a processing chamber having a shield disposed therein. Insulators are inserted to extend from an outer side of the shield through a thickness of the shield. A coil is mounted within the chamber by inserting fasteners through each insulator into bosses which-protrude outwardly from the coil body.

International Classification:

H02B 1/26

US Classification:

361622

Abstract:

Various embodiments provide safety disconnect systems for a power system. In one aspect, a safety disconnect system includes an enclosure operative to receive a plurality of input power lines into the enclosure and provide a plurality of output power lines out of the enclosure. Each input power line is coupled to and paired with a corresponding one of the output power lines, where each input power line and output power line is operative to provide power from a power source. A plurality of switches are provided in the enclosure, each of these switches coupled between an associated one of the pairs of input power line and output power line, and each switch operative to disconnect the associated input power line from the corresponding output power line.

International Classification:

H04J 316

US Classification:

370458

Abstract:

A method for transmitting packetized data in a cellular communication system uses a dynamic channel assignment scheme. In this aspect of the invention a data control channel is used in addition to the data traffic channel. The mobile end system uses the data control channel to send a request for assignment of a channel for transmission of data--such as a particular frequency/time-slot in a TDMA system. The network responds with the identification of a particular channel that may be used for a particular time period to transmit data. In this aspect of the invention there is no dedicated channel that is used for data transmission. Rather, the network determines a channel that will be free for the specified time period and assigns it for data transmission.

International Classification:

G06F 3/041
G09G 5/12
G06F 3/0488

Abstract:

An electronic device with a touch-sensitive surface displays a user interface of a first software application that is updated at a first display rate. While displaying a first frame of the user interface in accordance with the first display rate, the device detects respective movement of a touch input across the touch-sensitive surface. An application-independent touch processing module of the device selects a respective touch location of the touch input that was detected during the respective movement to identify as a representative touch location for the respective movement based on touch-processing criteria for the first software application, and sends to an application-specific portion of the first software application touch location information for the touch input that identifies the respective touch location as the representative touch location for the respective movement. The first software application updates the user interface in accordance with the touch location information.

International Classification:

G06F 3/041
G09G 5/12
G06F 3/0488

Abstract:

An electronic device, with a touch-sensitive surface and display, displays a user interface at a first display rate. While displaying the user interface, the device detects movement of a touch input across the touch-sensitive surface at a first detection rate that is higher than the first display rate. An application-independent touch processing module sends to an application-specific portion of the first software application touch location information for the touch input that identifies: one or more predicted locations of the touch input on the touch-sensitive surface, and one or more predicted intensity values of the touch input at one or more intensity locations of the touch input on the touch-sensitive surface. The first software application processes the touch location information and updated the user interface accordingly.
