A transient blocking unit (TBU) with integrated over-current protection and discrete over-voltage protection. In one example embodiment, the present innovations are embodied as a unit for protecting a circuit from high voltage and high current, comprising a core transient blocking unit with at least one high voltage device wherein the core transient blocking unit is integrated, and wherein the at least one high voltage device is discrete.

A method for fabricating an electrically isolated MEMS device having an outer stationary MEMS element and an inner movable MEMS element is provided that does not use a sacrificial layer. Rather, a pair of spacers are defined on the outer portions of the upper surface of a conductive wafer, and an insulating material is deposited thereon. The spacers are attached to a substrate to define an internal void therein. The wafer is then patterned to form the outer MEMS element as well as a conductive member for the inner MEMS element, separated from the outer MEMS element by a gap. A portion of the insulating layer that is disposed in the gap is then removed, thereby releasing the inner MEMS element from the stationary MEMS element.

Digital control of frequency and/or amplitude modulation techniques of an intracavity and/or extracavity AOM (60) facilitate substantially full extinction of a laser beam (90) to prevent unwanted laser energy from impinging a workpiece (80); facilitate laser pulse amplitude stability through closed-loop control of pulse-to-pulse laser energy; facilitate beam-positioning control including, but not limited to, closed-loop control for applications such as alignment error correction, beam walk rectification, or tertiary positioning; and facilitate employment of more than one transducer on an AOM (60) to perform any of the above-listed applications.

Methods and systems use laser pulses to process a selected structure on or within a semiconductor substrate. The structure has a surface, a width, and a length. The laser pulses propagate along axes that move along a scan beam path relative to the substrate as the laser pulses process the selected structure. The method simultaneously generates on the selected structure first and second laser beam pulses that propagate along respective first and second laser beam axes intersecting the selected structure at distinct first and second locations. The first and second laser beam pulses impinge on the surface of the selected structure respective first and second beam spots. Each beam spot encompasses at least the width of the selected link. The first and second beam spots are spatially offset from one another along the length of the selected structure to define an overlapping region covered by both the first and the second beam spots and a total region covered by one or both of the first and second beam spots. The total region is larger than the first beam spot and also larger than the second beam spot. The method sets respective first and second energy values of the first and second laser beam pulses to cause complete depthwise processing of the selected structure across the width of the structure in at least a portion of the total region.
摘要:
Merged devices for transient blocking. A pass transistor is placed so that its body potential drives the gate of a depletion-mode JFET-type blocking transistor. Thus a transient which appears on an external terminal is very rapidly propagated to shut off the blocking transistor, before large numbers of carriers can be injected. Preferably a shunt device is also used to drop high potentials which may appear at the same time. This connection can be particularly useful in power or data input terminals.

A microelectromechanical system (MEMS) device is used to transfer power from a source generator to a power generator that delivers electrical power to a load, while maintaining electrical isolation between the source generator and power generator for size critical applications where transformers or coupling capacitors would not be practical, but where electrical isolation is desired.

A method of delivering advertising in an online environment includes determining an intent of a user interacting with an e-commerce website, and determining a hurdle rate that is based at least on the user intent and which identifies a threshold amount to be bid by an advertiser in order to display an advertisement to the user. The method further includes selecting, from a plurality of advertisements, an optimal advertisement having an advertiser bid that exceeds the hurdle rate, and displaying the optimal advertisement to the user in an interface of a client computer system.

A method of delivering advertising in an online environment includes determining an intent of a user interacting with an e-commerce website and determining a hurdle rate, based at least on the intent of the user, that identifies a threshold amount to be bid by an advertiser in order to display an advertisement to the user interacting with the e-commerce website. The method may further include selecting, from a plurality of advertisements, one or more optimal advertisements having a combined advertiser bid that exceeds the determined hurdle rate. The method may further include providing one or more controls in a user interface of a client computer system, each of the controls being associated with a respective advertisement of the one or more optimal advertisements and adapted to enable the user to select one or more of the controls, and providing an element, responsive to an input of the user, that is adapted to display, to the user, the respective advertisements selected by the user.

A convertible self-checkout system includes a base and a stand rotatably mounted to the base. The stand includes an input/output device facing in a first direction and a product scanner, and the stand is positionable relative to the base in at least a first angular position and a second angular position. The input/output device is an interactive video display, and the interactive video display has a first mode corresponding to the first angular position and a second mode corresponding to the second angular position. A sensor determines an angular position of the stand relative to the base and communicates the angular position to the interactive video display. The stand further includes a video display facing in a second direction substantially opposite from the first direction.
