Abstract:
A protection circuit (FIG. 2) for an integrated circuit is disclosed. The protection circuit comprises a protection transistor (MN0) having a current path coupled between a first terminal (VDD) and a second terminal (GND). A current mirror (MP1, MP0, MN2, MN1) has an output terminal coupled to a control terminal of the protection transistor. A delay circuit (R1, C0) is connected between the first and second terminals and has a delay output terminal connected to a first input terminal (MN1) of the current mirror.
Abstract:
Systems and methods are disclosed for securely transferring research data relating to media exposure data, such as radio, television, streaming media and the Internet. A plurality of portable computing devices seek and bond to a collector via Bluetooth in a specific area, such as a household. The collector authenticates itself with each of the portable computing devices and vice versa where the collector arranges a secure research data transfer session with each respective device using exchanged authentication files. As each secure session is made, each portable computing device transmits stored research data during the session.
Abstract:
A computer-implemented system and method for establishing media data exposure, where a media device, such as a computer, radio, television and the like, receive media data and produces research data from it. The research data may be based on computer-based or computer network-based characteristics, ancillary codes or audio signatures. As the research data is being produced, an inductive coupling is sought for nearby portable computer devices. Once a portable computing device inductively couples to the media device, information is transferred, allowing a system to determine and/or verify that specific users were exposed to particular media data.
Abstract:
Holes in semiconductor processing reactor parts are sized to facilitate deposition of protective coatings, such as by chemical vapor deposition at atmospheric pressure. In some embodiments, the holes each have a flow constriction that narrows the holes in one part and that also divides the holes into one or more other portions. In some embodiments, the aspect ratios of the one or more other portions are about 15:1 or less, or about 7:1 or less, and have a cylindrical or conical cross-sectional shape. The holes are coated with a protective coating, such as a silicon carbide coating, by chemical vapor deposition, including chemical vapor deposition at atmospheric pressure.
Abstract:
In an ESD device for fast switching applications based on a BSCR or NLDMOS-SCR, an anode junction control electrode is provided by not connecting the anode electrode to the collector of the BSCR or to the drain of the NLDMOS-SCR, and a cathode junction control electrode is provided by forming an additional n+ region in the BSCR or an additional p+ region in the p-well of the NLDMOS-SCR. The triggering voltage of the ESD device is adjusted after a time delay by controlling one or both of the control electrodes using an RC-timer-driver circuit.
Abstract:
In a SiGe BJT process, a diode is formed by defining a p-n junction between the BJT collector and BJT internal base, blocking the external gate regions of the BJT and doping the emitter poly of the BJT with the same dopant type as the internal base thereby using the emitter contact to define the contact to the internal base. Electrical contact to the collector is established through a sub-collector or by means of a second emitter poly and internal base both doped with the same dopant type as the collector.
Abstract:
A method and system for distributed computing interface are disclosed. According to one embodiment, a computer implemented method comprises accessing a collaborative interface, wherein the collaborative interface comprises persistent shared space, wherein visual representation of the collaborative interface is identical for each client accessing the collaborative interface. In a single action, an object is dragged into the collaborative interface and the object is displayed in real time in the collaborative interface. The object is accessible to other clients in the collaborative interface and the state of the object is continuously synchronized. The object is manipulated in the collaborative interface and other clients accessing the collaborative interface are viewed.

Abstract:
Inserts are used to line openings in parts that form a semiconductor processing reactor. In some embodiments, the reactor parts delimit a reaction chamber. The reactor parts may be formed of graphite. A layer of silicon carbide is deposited on surfaces of the openings in the reactor parts and the inserts are placed in the openings. The inserts are provided with a hole, which can accept another reactor part such as a thermocouple. The insert protects the walls of the opening from abrasion caused by insertion of the other reactor part into the opening.
